No invasive test will be done without a discussion with the patient about risks and benefits of the procedure. ## Accessibility Help URL: https://www.heartcare4life.com/accessibility Summary: A practical guide to navigating heartcare4life.com: keyboard navigation, skip links, text size, contrast, screen readers and browser support.

Accessibility Statement HeartCare4life is committed to making this website usable by everyone, including people with visual, hearing, cognitive, and motor disabilities. Heart care is not optional information. A patient who cannot read our site cannot learn about their condition, find our offices, or request an appointment. We treat accessibility as part of patient care, not as a legal checkbox. This is our formal conformance statement. For practical instructions on navigating the site, see our Accessibility Help page. Conformance Target We aim to conform to the Web Content Accessibility Guidelines (WCAG) 2.1 at Level AA, published by the World Wide Web Consortium. WCAG 2.1 AA is the standard commonly referenced in connection with the Americans with Disabilities Act and Section 508 of the Rehabilitation Act. We describe our status as partially conformant. That means most of the site meets the standard, and we continue to work on the parts that do not. Measures We Take Accessibility is built into how this site is made, not added afterward. Specifically: - Semantic HTML. Pages use real headings, lists, landmarks, and buttons, in a correct and logical order, so assistive technology can convey the structure of a page. - Keyboard navigation. Every interactive element can be reached and operated with a keyboard alone. Focus order follows the visual reading order, and the focused element is always visibly outlined. - Skip link. A "Skip to content" link is the first focusable item on every page, letting keyboard and screen reader users bypass the navigation. - Text alternatives. Meaningful images carry descriptive alternative text. Decorative images are marked so screen readers pass over them. - Color contrast. Text and interface colors are chosen to meet the WCAG 2.1 AA contrast ratios of 4.5 to 1 for normal text and 3 to 1 for large text. - Color is never the only cue. Links, errors, and states are distinguished by more than color alone. - Responsive, reflowing layout. Content reflows to a single column and remains readable at 200 percent zoom without horizontal scrolling. - Labeled forms. Every form field has a programmatically associated label, and error messages are described in text. - Reduced motion support. Animation is suppressed for visitors whose devices request reduced motion. - Descriptive page titles and link text. Links make sense when read out of context. Known Limitations We are candid about where we fall short. Some third-party content embedded in this site, including video players and mapping widgets, is not fully under our control. We choose accessible providers where we can and work around the gaps where we cannot. Some older documents and patient forms available for download may not be fully tagged for screen readers. If you need any form or document in an accessible format, call us and we will provide it another way at no cost to you. How We Review Accessibility is checked as part of building and updating the site. We use automated testing, manual keyboard testing, and review with screen readers. We re-check pages when they change rather than auditing once and moving on. Report an Accessibility Problem If you encounter a barrier on this website, please tell us. Your report helps us fix it for everyone. Tell us the page address, what you were trying to do, and what happened. If you can, mention the browser and any assistive technology you were using. That detail helps us reproduce the problem quickly. - Bonita and South San Diego: (619) 585-0476 - Redding and Northern California: (530) 433-5427 - Online: use our contact page We aim to respond to accessibility reports within five business days. If we cannot fix a problem right away, we will tell you and give you another way to get the information or service you need in the meantime. Office hours are Monday through Thursday, 9:00 am to 5:00 pm, and Friday, 9:00 am to 12:00 pm. Feedback We welcome comments on how to make this site work better for you. Accessibility work is never finished, and reports from the people who use the site are the most useful input we get. ## Appointments URL: https://www.heartcare4life.com/appointments Summary: Compare online booking, telehealth, concierge and international care, see office hours in Bonita, San Diego and Redding, and what to bring to a first visit. There is more than one way to see Dr. Nanavati, and the right one depends on why you are coming and where you are. Choosing How to Book Booking online is the fastest route for most people. Request a time, tell us briefly why you want to be seen, and the office will call to confirm and to sort out any referral or authorization your plan requires. Telehealth suits follow-up visits, reviewing test results, medication adjustments, and second opinions where the records tell most of the story. It does not suit a first evaluation of chest pain or a new murmur, because those need an examination and testing in person. Concierge care is for patients who want direct access, longer appointments, and closer coordination of their cardiac care over time. International patients need coordination a normal booking does not cover, including records review before you fly and scheduling that accounts for your trip. Where You Will Be Seen We see patients in Bonita and South San Diego, in North San Diego, and in Redding. Selected Saturdays are available in Redding by appointment. See our locations for addresses and directions. Call (619) 585-0476 for the San Diego area or (530) 433-5427 for Redding. Office hours are Monday through Thursday, 9:00 am to 5:00 pm, and Friday, 9:00 am to 12:00 pm. Before You Book Check two things first. Whether your plan requires a referral from your primary care physician, and whether the test you have been sent for needs prior authorization. Our insurance page explains both. Sorting them out in advance is what makes an appointment go smoothly. What to Bring Your insurance card, a photo ID, a current list of medications with doses, and any prior cardiac records you have. Old ECGs, echocardiograms, stress tests, and catheterization reports are genuinely valuable. A previous tracing can turn an ambiguous finding into a clear one. If you are unsure which visit type fits, call and describe the situation. Urgent Symptoms If you have chest pain, pressure, shortness of breath, fainting, or you think you may be having a heart attack, do not book an appointment. Call 911. ## Concierge URL: https://www.heartcare4life.com/appointments/concierge Summary: Dr Vimal Nanavati, a cardiologist at HeartCare4life in Redding, Bonita and Chula Vista, CA offers concierge medicine. What is Concierge Medicine? Concierge medicine is a care program whereby a physician charges you an out-of-pocket retainer fee for a range of highly personalized services.

Coronary angiogram showed high-grade long lesion in the native LAD (bypass conduit to LAD was occluded). See BEFORE picture. The patient received two DES stents with complete resolution of the blockage (see AFTER picture). His chest pain resolved after the stent procedure. - - 47y/o diabetic female with chest pain and dysrhythmia showing NSVT and slight elevation in Troponin. Coronary angiogram shows a severe eccentric 95% stenosis ( see BEFORE). She received a single DES stent in LAD with resultant resolution of the stenosis and excellent flow( see AFTER STENT). Her symptoms resolved after flow in the LAD was restored. - - - 73 y/o female with Diabetes, found to have abnormal stress test prior to planned foot surgery. This lead to angiogram and subsequent percutaneous intervention of the ostium( origin) of the branch off the left circumflex artery called obtuse marginal. A single stent was used to open the blockage. - - - 72 y/o female US National traveling from Mexico having chest pain. - - 57 y/o male with chest pain. He had an abnormal stress test which led to a CT angiogram imaging test showing a blockage. This led to the angiogram shown. - - 70 y/o female having “indigestion” which gets better with Sublingual nitroglycerin. Moreover, she had an abnormal stress test. - - - - 73 y/o female presents with accelerating symptoms of angina. Angiogram pictures show Left Anterior Descending artery (LAD) is severely blocked(stenosed). She receives an initial balloon dilatation and finally a drug eluting stent is implanted (see final result). She no longer has chest pain. - - 82 y/o man presents with new, worsening chest pain. He’s had a history of bypass surgery and multiple stents placed in the past. He was referred for coronary angiogram. Findings are seen in the “ Before” picture, followed by the therapeutic stent placed. - - 75 y/o female having chest pain with minimal exertion. After stent, no more chest pain. - - 75 y/o female I placed a stent in her diagonal artery 2008, comes to my office complaining of shortness of breath and chest pain. First picture was X-ray showing silhouette of stent. Second picture shows coronary angiogram showing stent to be widely patent today December 14,2022 (14 years later). - - - These are the 3 pictures of the 41 y/o male I described on earlier post. They show before (the blockages in the coronary arteries look like pinched off area), during and after the stents were successfully implanted. It’s imperative to remain on the anti-platelet medication for at least one year. - - The coronary artery is what shows up in black. Contrast dye during X-ray appears black. The pinched off area in the “ before” picture is the stenosis. The “after” picture no longer shows the stenosis because a balloon opened it followed by a metal stent to prop it open. The balloon is removed, leaving only the metallic stent. - - Women don’t get classic anginal chest pain. This is the perfect example: 82 y/o female who stated she had Right lower abdominal pain which is identical to her pain she had before her stent 10 years ago. After we reopened the stent restenosis, her abdominal pain resolved. She went home the day after her stent. - - 65 y/o male presents with acute chest pain and dizziness. EKG done in Emergency room shows ST elevation. Code STEMI called. The complete blockage was re-opened with a balloon and stent was placed. Symptoms and EKG improved. He went home 2 days later on anti-platelet medication he will need to stay on for one year. - - An 58 y/o man presented with chest pain while traveling through San Diego. Before picture shows the tight blockage and “After” shows the results after emergency stent procedure performed by Dr. Nanavati.

Read more. Understanding your options Most cardiology decisions come down to a choice between two reasonable paths. Stent or medication. Treadmill test or nuclear scan. Wrist access or groin access. Patients are often handed these choices during a stressful appointment, then go home and try to make sense of them alone. These pages exist for that moment. Each one takes a common decision and lays it out plainly: what each option involves, where it is done, what anesthesia is used, how long recovery takes, and which patients each option suits best. We try to be genuinely balanced. Where good evidence favors one option, we say so, even when it points toward surgery rather than a catheter procedure, or toward medication rather than any procedure at all. Where the evidence is close, we say that too, because in those situations your anatomy, your other medical conditions, and your own priorities carry real weight. Nothing here replaces an examination. The same symptom can mean different things in different people, and the right answer depends on your test results, your history, and a conversation with a physician who has reviewed them. Dr. Vimal Nanavati, MD, FACC is board certified in cardiology and interventional cardiology, with 32 years in practice. He founded HeartCare4life in 1997 and sees patients in South San Diego (Bonita), North San Diego, and Redding.

The short answer Angioplasty and bypass surgery both restore blood flow to heart muscle starved by blocked arteries. Angioplasty is a catheter procedure. A doctor threads a thin tube through an artery in your wrist or groin. A balloon opens the narrowing. A small metal mesh stent usually stays behind to hold it open. Bypass surgery is open heart surgery. A heart surgeon builds new routes around the blockages. The new routes use blood vessels borrowed from your chest, arm, or leg. For one blocked artery, or two in a simple pattern, angioplasty is usually a reasonable first choice. For left main disease, for three vessel disease, and especially for people with diabetes, bypass surgery has the stronger long term survival record. The right answer depends on which arteries are narrowed and how well your heart pumps. It also depends on your other health problems, and on what matters most to you. Neither option cures the disease itself. Both work best alongside medicine and lifestyle change. How they differ at a glance | | Angioplasty with stenting | Bypass surgery (CABG) | | --- | --- | --- | | What it involves | A balloon opens the narrowed segment from inside the artery. A stent usually holds it open. | A surgeon grafts healthy vessels onto the coronary arteries beyond the blockages. That creates new channels for blood. | | Where it is done | Hospital cardiac catheterization lab. Dr. Nanavati performs these at affiliated hospitals. | Hospital operating room, by a cardiac surgeon. Dr. Nanavati refers and coordinates, he does not perform surgery. | | Anesthesia or sedation | Local anesthetic at the access site plus light conscious sedation. You are awake but relaxed. | General anesthesia. You are fully asleep and on a breathing machine. | | Typical recovery | Same day discharge or one night. Most people resume light activity within a week. | Four to seven days in hospital. Six to twelve weeks before full activity, longer if the breastbone was divided. | | Best suited for | One or two vessel disease, favorable anatomy, an acute heart attack, or higher surgical risk from age or frailty. | Left main disease, three vessel disease, reduced pumping function, diabetes with multi vessel disease, or blockages unsuitable for a catheter. | Angioplasty in detail Angioplasty reopens a narrowed artery from the inside. Doctors also call it percutaneous coronary intervention. The balloon step has a name of its own, PTCA, short for percutaneous transluminal coronary angioplasty. In nearly all modern cases, a drug eluting stent goes in during the same session. A stent is a tiny metal scaffold. Its coating releases medicine that makes scar tissue less likely to grow back. Our coronary stenting page describes the device itself. The appeal is speed and gentleness. There is no chest cut, no heart lung machine, and no divided breastbone. Angioplasty is the treatment of choice when a heart attack comes from a suddenly blocked artery. Minutes of delay mean heart muscle lost for good. MedlinePlus describes it as the standard emergency approach in that setting. The tradeoff is how long the result lasts at the treated spot. Stented segments can narrow again. You will also need dual antiplatelet medicine afterward, usually aspirin plus a second drug. Your doctor sets how long you take it. Skipping those pills early raises the risk of a clot forming inside the stent. Bypass surgery in detail Coronary artery bypass grafting routes blood around blockages instead of through them. For the main vessel, surgeons prefer an artery from inside the chest wall, the internal mammary artery. Artery grafts stay open for decades. Vein grafts from the leg cover the other targets. The NHLBI overview of bypass grafting explains the operation and its risks in plain language. A graft attaches beyond the diseased segment. So bypass protects the whole area downstream, not just one narrowed point. That is why it holds up better when disease is spread out or full of calcium. Randomized trials, summarized in American College of Cardiology guidelines, show a survival advantage for surgery in patients with diabetes and multi vessel disease. The same holds for most left main disease with complex anatomy. That is a real finding, and it points away from the catheter based option. Dr. Nanavati will tell you so directly when your arteries fit that picture. The cost is a harder recovery. Expect several days in hospital and weeks of limited lifting. Expect a stretch of fatigue and broken sleep as well. Feeling foggy in the first weeks is common, and it usually passes. How Dr. Nanavati decides which is right for you The decision starts with a picture of your arteries. That picture comes from a coronary CT angiogram or a catheter angiogram. From there, several things carry weight. Blockage pattern matters most. Left main narrowing, and disease in all three major vessels, tilt strongly toward surgery. Single spots in one or two vessels usually favor stenting. Pumping strength is the second factor. An echocardiogram measures it as the ejection fraction. When that number is low, trials have generally shown better long term results with surgery. Diabetes changes the math. In diabetes, coronary disease tends to be spread out and to move faster. That is why guidelines favor bypass for multi vessel disease in this group. The shape of the blockage counts too. Heavy calcium, long segments, and fully blocked vessels make a lasting stent result harder. So do vessels that branch right at the blockage. Finally, other risks matter. Older age, frailty, past chest surgery, severe lung disease, or weak kidneys can make an operation riskier than the disease. In coronary artery disease, the goal is the option that gives you the most good years. It is not the most aggressive one. Medicine first is a real third path. It fits stable symptoms when the anatomy is not high risk. Our stent vs medication page covers that comparison. Complex cases deserve a heart team review. That means a cardiologist and a cardiac surgeon reading your films together. Ask for one. Questions to ask your cardiologist - Which arteries are blocked, how severely, and where exactly are the narrowings? - Is my anatomy simple or complex, and does a surgeon agree with that read? - Given my diabetes status and my ejection fraction, what does the trial evidence favor? - If we stent, how long will I need dual antiplatelet therapy, and can I take it safely? - What would happen if we treated this with medicine and lifestyle change first? - Has a cardiac surgeon reviewed my images, and can we hold a heart team discussion?

Dr Vimal Nanavati explains, at HeartCare4life in San Diego and Redding, CA. The short answer Every interventional cardiologist is also a cardiologist. The reverse is not true. Think of two kinds of heart doctor. The first trains in internal medicine, then does a heart fellowship. This is the general or clinical cardiologist. They spend a career finding heart disease and keeping it under control. Their tools are office visits, tests, and pills. The second does all of that training, then adds a year or more. That extra year covers treatment through thin tubes called catheters. It earns a second board certificate in interventional cardiology. That work includes opening blocked arteries with balloons and stents. Neither role is better. They answer different needs. A general heart doctor handles most heart problems alone. That includes high blood pressure, cholesterol, heart failure, and stable chest pain. You need the second kind when a blockage may need catheter treatment. Many heart doctors, including Dr. Nanavati, hold both certificates. One doctor can then carry the case from start to finish. How they differ at a glance | | General cardiologist | Interventional cardiologist | | --- | --- | --- | | What it involves | Internal medicine residency, then a heart fellowship. Diagnosis, medicine, prevention, and reading tests. | The same training, plus an extra fellowship and a second board certificate in catheter treatment. | | Where it is done | Office visits, hospital rounds, and testing rooms with no cuts. | The same places, plus the hospital lab where catheter procedures are done. | | Anesthesia or sedation | None. Office visits, echocardiograms, stress tests, and monitors are awake and painless. | None for office care. Procedures use numbing medicine at the entry site, plus light sedation that keeps you awake. | | Typical recovery | None. Follow up is set around medicine changes and repeat testing. | None after office visits. After a catheter procedure, hours of watching and several days of limited activity. | | Best suited for | Risk factors, cholesterol, blood pressure, heart failure, palpitations, murmurs, and stable symptoms. | Known or suspected blockages needing catheter tests or treatment, heart attack care, and structural procedures. | The general cardiologist in detail A general heart doctor works out what is wrong and keeps it under control. Most of that work is talking, examining, and reading tests. It is also where most heart outcomes are decided. The tests need no cuts. An echocardiogram shows the valves and pumping strength. An EKG shows the electrical pattern. A treadmill stress test shows how the heart acts under effort. Holter monitoring records the rhythm for a full day. Advanced lipid testing sharpens the cholesterol risk. The treatments are mostly drugs. Statins, blood pressure pills, diabetes control, blood thinners for atrial fibrillation, heart failure drugs, quitting smoking, and steady exercise all change long term outcomes. They change them more than any single procedure does. The CDC and the American Heart Association both stress that risk factor care is the core of heart care. Heart care has other branches too. A rhythm doctor, or electrophysiologist, treats rhythm problems with ablation and implanted devices. Heart failure doctors manage a badly weakened pump. Imaging doctors focus on advanced scans. The interventional cardiologist in detail This is the procedure branch of heart care. For short, we will say procedure doctor here. After the standard heart fellowship, this doctor trains further in catheter skills. Then comes a separate board exam. The daily work includes coronary angiography, a dye test of the heart arteries. It also includes angioplasty, coronary stenting, and emergency care for heart attacks. The tube goes in at the wrist or the groin. Our transradial vs transfemoral angiogram page compares those two routes. Many of these doctors also treat leg arteries and veins. Some do structural heart procedures. Two points deserve plain words. First, a procedure doctor still does general heart care. Prescribing statins and adjusting blood pressure pills is part of the job. It is not a lesser task handed to someone else. Second, being able to do a procedure is no reason to have one. For stable heart artery disease, medicine often works as well as a stent at preventing heart attacks. Our stent vs medication page covers that point. A good procedure doctor says no often. Heart surgery is a separate field. Bypass operations are done by heart surgeons. A procedure doctor refers and coordinates when surgery is the better answer. See angioplasty vs bypass surgery. How Dr. Nanavati decides which is right for you In practice, patients rarely have to choose. The referral usually comes from a primary care doctor. The heart doctor then decides what the case needs. Symptoms set the direction. Chest pain with effort, shortness of breath, palpitations, or an odd EKG start with an office visit and tests that need no cuts. Test results then decide the next step. A strongly abnormal stress test moves the case toward catheter testing. So does imaging that shows real coronary artery disease. So does a rising cardiac blood test. Urgency beats everything. Chest pain at rest, or a suspected heart attack, means calling 911 and going to an emergency room. Do not book an office visit. Details are on our chest pain page. Staying with one doctor has real value. That doctor may run the tests, read the angiogram, do the procedure if you need one, and manage the pills after. Less is then lost between handoffs. Complex cases sometimes need a wider team. A heart surgeon, a rhythm doctor, or a vein and artery doctor may be the right person. A good heart doctor says so. MedlinePlus has background reading on heart conditions. Questions to ask your cardiologist - What are your board certifications, and when did you last renew them? - Will you manage my medicines yourself, or hand that back to my primary care doctor? - If I need a procedure, will you do it, and where? - If my case needs surgery or a rhythm doctor, how does that referral work? - Who reads my test results, and how soon will I hear? - What can be done at your office, and what needs a hospital?

Dr Vimal Nanavati explains when each heart test fits best, at HeartCare4life in San Diego and Redding, CA. The short answer Both tests show the coronary arteries, but they get to the picture very differently. A coronary CT angiogram is a scan. You lie in a CT machine, and contrast dye goes in through an arm vein. A computer then builds the arteries in three dimensions. Nothing enters your heart. An invasive angiogram is a catheter procedure. A thin tube is guided from your wrist or groin to the mouth of each coronary artery. Dye is injected right there, and live X ray images are recorded. Say you have new chest pain, no known heart disease, and low to intermediate risk. The CT scan is usually the better first test then. It is very good at ruling disease out. Now say you have unstable symptoms, a heart attack, strongly abnormal stress testing, or known severe disease. The catheter study is the right choice then. It both confirms the problem and allows immediate treatment. How they differ at a glance | | Coronary CT angiography | Invasive coronary angiogram | | --- | --- | --- | | What it involves | A CT scanner images the heart while iodine contrast flows through an arm vein. Often a beta blocker slows your heart rate first. | A catheter is threaded through a wrist or groin artery to the coronary openings. Contrast is injected directly and filmed on X ray. | | Where it is done | Hospital or outpatient imaging center, ordered and read through the cardiology office. | Hospital cardiac catheterization lab. Dr. Nanavati performs these at affiliated hospitals. | | Anesthesia or sedation | None. You lie still and hold your breath for a few seconds. | Local anesthetic at the access site plus light conscious sedation. You stay awake. | | Typical recovery | None. You go home right away and drive yourself. | Two to six hours of observation. Wrist access allows sitting up sooner. Avoid heavy lifting for several days. | | Best suited for | Ruling out coronary disease in stable chest pain, unclear stress tests, and younger patients with low calcium burden. | Unstable symptoms, heart attack, high risk stress results, and any situation where a stent may be placed in the same visit. | Coronary CT angiography in detail Coronary CT angiography maps the arteries in detail without entering one. Its greatest strength is what doctors call negative predictive value. When the scan shows clean arteries, that result is highly reliable. The chest pain workup can then move on to other causes. The 2021 chest pain guideline framework summarized by the American College of Cardiology supports CT angiography as a first line test for stable chest pain. It applies to patients at intermediate risk who have no prior coronary disease. That is a meaningful nod to the test that stays outside the artery. There are limits. Heavy calcium in the artery wall creates glare on the images. That glare can make a narrowing look worse than it is. A fast or irregular rhythm blurs the pictures, so atrial fibrillation is a practical obstacle. The scan uses ionizing radiation and iodine contrast. Contrast calls for care when kidney function is reduced. General background on CT imaging is available from MedlinePlus. Most importantly, a CT scan cannot treat anything. If it finds a severe blockage, you still need a catheter procedure. Invasive angiography in detail An invasive coronary angiogram is still the reference standard for mapping the coronary arteries. One route is the radial artery at the wrist, described on our transradial angiogram page. The other is the femoral artery in the groin, described on our transfemoral angiogram page. Our transradial vs transfemoral page compares the tradeoffs. Live imaging shows the narrowing and the blood flow through it. A pressure wire can be added to test whether a borderline spot really limits flow. If a major blockage is confirmed, coronary stenting can often be done in the same procedure. That spares you a second appointment. The risks are small but real, and they are not zero. Bleeding or bruising at the access site is the most common. Contrast can stress the kidneys. Rare problems include artery injury, arrhythmia, and stroke. The American Heart Association and the National Heart, Lung, and Blood Institute describe the procedure and its risks in detail. How Dr. Nanavati decides which is right for you Urgency comes first. Chest pain at rest, rising troponin blood tests, or EKG changes that suggest an active blockage all mean one thing. Go straight to the catheterization lab. Details are on our chest pain page. In stable cases, the odds of disease shape the choice. A patient with unusual symptoms and few risk factors needs a test that reliably rules disease out. The CT scan fits that job well. Past findings matter. Known coronary artery disease, earlier stents, or earlier bypass grafts make CT less useful. Metal and grafts muddle the images. Kidney function and rhythm are practical filters. Both tests use contrast, but a fast or irregular rhythm affects only the CT. Sometimes a stress test comes first instead. Does the narrowing actually limit blood flow during effort? A stress study may answer that more directly. See our treadmill vs nuclear stress test comparison. One rule guides all of it. Do not enter an artery unless what you learn will change what happens next. Questions to ask your cardiologist - What is the specific question this test needs to answer for me? - Given my risk profile, is a non invasive scan likely to be conclusive? - Does my calcium score or my heart rhythm limit the accuracy of a CT scan? - If the catheter study finds a blockage, would you treat it during the same procedure? - How will my kidney function be protected from the contrast dye? - What happens if the test result is borderline rather than clearly normal or abnormal?

Dr Vimal Nanavati explains what each heart test shows and when you need both, at HeartCare4life in San Diego and Redding, California. The short answer These two tests answer different questions, so one does not replace the other. An EKG records the heart's electrical signals through stickers on your chest, arms, and legs. It is also written ECG, or electrocardiogram. The test takes about five minutes. It shows rhythm problems, signs of a past heart attack, and patterns of electrical strain. An echocardiogram is an ultrasound picture of the heart in motion. It shows chamber size, valve function, and the thickness of the muscle walls. It also shows fluid around the heart, and how strongly the heart squeezes. Does your cardiologist want to know how your heart behaves electrically? The EKG answers that. Is the question how your heart is built and how well it pumps? The echocardiogram answers that. Most heart workups start with an EKG, because it is quick and low cost. An echocardiogram is added when structure or pump function is in question. How they differ at a glance | | Electrocardiogram (EKG or ECG) | Echocardiogram | | --- | --- | --- | | What it involves | Ten sticky electrodes record the heart's electrical activity as a tracing on paper or screen. Nothing is injected. | An ultrasound probe with gel moves across your chest. Sound waves create moving images of the heart and its valves. | | Where it is done | In the office, at the bedside, or in an emergency room. Performed in office at HeartCare4life. | In the office ultrasound room. Performed in office at HeartCare4life. | | Anesthesia or sedation | None. You lie still and breathe normally. | None for a standard chest wall study. Sedation applies only to the swallowed probe version, done in hospital. | | Typical recovery | None. You leave immediately and drive yourself home. | None. Gel is wiped off and you resume normal activity. | | Best suited for | Rhythm disturbances, suspected heart attack, conduction blocks, and rapid screening for chest pain. | Heart murmurs, valve disease, heart failure, shortness of breath, and measuring ejection fraction. | Electrocardiogram in detail An electrocardiogram captures the electrical wave that runs through the heart with every beat. Electrodes on the skin sense that wave from twelve angles. That is why it is often called a twelve lead EKG. Its strength is speed and breadth. Within seconds a cardiologist can see whether the rhythm is regular. The tracing shows whether the upper and lower chambers are talking to each other normally. It can suggest that an artery is blocked right now. It can also show the scar left by an old heart attack. In a chest pain workup it is the first test done, because it sorts emergencies from everything else. The American Heart Association describes this role in detail. Its limit is the snapshot. An EKG records perhaps ten seconds. If your palpitations come twice a week, the tracing will very likely be normal. A wearable monitor is the answer then. Our Holter vs event monitor page and the arrhythmias page cover those devices. An EKG also says little about valves. A leaking valve can produce a perfectly normal tracing. Echocardiogram in detail An echocardiogram uses sound waves rather than radiation. We do the standard version in our offices, transthoracic echocardiography. The probe simply rests on the outside of the chest. It produces a live moving image. Doppler settings add color and sound to show the direction and speed of blood flow. That is how valve leaks and narrowings are graded. The most quoted result is the ejection fraction. It is the share of blood the left ventricle pushes out with each beat. A normal value sits roughly between 55 and 70 percent. The American Heart Association echocardiogram page explains what the numbers mean. The scan also finds fluid around the heart and clots inside the chambers. It finds thickened muscle from years of high blood pressure, and heart defects present from birth. Its limit is that it does not read rhythm. It also depends on picture quality. That quality can be poor in patients with lung disease or a larger body. Another imaging test may be needed then. How Dr. Nanavati decides which is right for you The symptom drives the test. Palpitations, fainting, or an irregular pulse point to the electrical side, so the EKG comes first. Shortness of breath, ankle swelling, a murmur heard on exam, or known valve disease point to ultrasound. Order matters more than choice. Almost every new heart patient gets an EKG, because it is fast and it changes decisions. The echocardiogram follows when your history, your exam, or the EKG itself raises a question about structure. An abnormal EKG often triggers an echocardiogram. Examples are voltage that suggests thick walls, a pattern of past heart attack, or a new bundle branch block. Each one justifies imaging the muscle directly. Neither test measures blood flow under stress. If chest pain comes on with effort, a stress study is the right next step. Our treadmill vs nuclear stress test page explains those options. Both tests are safe, painless, and free of radiation. So the order usually comes down to cost and to what each test can tell us, not to risk. General background on heart testing is available from MedlinePlus and the National Heart, Lung, and Blood Institute. Questions to ask your cardiologist - Which specific question are we trying to answer with this test? - Will an EKG alone be enough, or should we image the heart structure too? - What is my ejection fraction, and is it in the normal range? - If my symptoms come and go, would a longer rhythm monitor be more useful? - Do my results need to be repeated, and if so, how often? - Does anything in these results change my medicines?

Dr Vimal Nanavati explains how symptom frequency decides which heart rhythm recorder you need, in San Diego and Redding, CA. The short answer The choice comes down to one question: how often do your symptoms happen? A Holter monitor records every heartbeat without a break, usually for 24 or 48 hours. It is the right tool when palpitations, dizziness, or skipped beats happen most days. A short recording window will then almost certainly catch an episode. An event monitor is worn much longer, commonly two to four weeks. But it saves only selected stretches rather than everything. Some versions record when you press a button. Others detect abnormal rhythms on their own. That design suits symptoms that arrive once a week or once a month. Wear a two day Holter for a monthly symptom and you usually get a normal result that proves nothing. Wear a month long monitor for daily symptoms and you do more work than the answer requires. Match the recording window to how often your symptoms come. The test is then far more likely to be useful. How they differ at a glance | | Holter monitor | Event monitor | | --- | --- | --- | | What it involves | Chest electrodes wired to a small recorder, or a sticky patch. Every beat is stored without a break. | A patch or small wearable worn for weeks. It stores rhythm strips triggered by your symptoms or by automatic detection. | | Where it is done | Fitted in the office at HeartCare4life, then worn at home during normal activity. | Fitted in the office, then worn at home. Some models send data wirelessly for review. | | Anesthesia or sedation | None. It is entirely external. | None for wearable models. An implantable loop recorder requires only a local anesthetic. | | Typical recovery | None. You return the device or mail the patch back when the recording ends. | None. Skin irritation under adhesive is the most common complaint. | | Best suited for | Daily or near daily palpitations, monitoring rate control, counting how many abnormal beats occur in a day. | Infrequent palpitations, unexplained fainting, and confirming or excluding intermittent atrial fibrillation. | Holter monitoring in detail Holter monitoring is continuous ambulatory electrocardiography. Because nothing is missed, it answers counting questions that no other test can. How many premature beats do you have in a day? What were your slowest and fastest heart rates overnight? Do pauses happen while you sleep? Is your rate control medicine working? You keep a symptom diary while wearing it. That diary is the point of the test. You note "felt fluttering at 3:15 pm." Matching that note to the tracing at 3:15 pm turns a recording into a diagnosis. The National Heart, Lung, and Blood Institute explains this link clearly. The limit is the short window. A standard 24 or 48 hour study captures only those particular days. A completely normal Holter does not rule out an arrhythmia. It simply means nothing happened while you wore it. Patients often assume otherwise, and that mistake delays diagnosis. A standard resting EKG covers only about ten seconds. So a Holter is already a large step up in coverage. Event and extended monitoring in detail Event monitoring stretches the watching window. Our 7 to 10 day ambulatory rhythm monitor is a common middle ground. It is a single sticky patch worn without a break for over a week. It is comfortable enough to sleep and shower in. Longer wearable monitors reach about 30 days. Many use looping memory. The device holds the rhythm in a rolling buffer, then permanently saves the seconds before and after a trigger. That matters when an episode makes you faint, because you cannot press a button while unconscious. Symptoms that come only every few months may need an implanted device. Loop recorder implantation and interrogation places a small monitor under the skin of the chest. It can watch for up to about three years. It is used mainly for fainting with no known cause. It also searches for silent atrial fibrillation after a stroke of unknown cause. Longer monitoring has costs. The adhesive can irritate skin, there is more data to review, and implants need a minor procedure. Descriptions of the rhythm disorders these devices look for are available from MedlinePlus and the American Heart Association. How Dr. Nanavati decides which is right for you How often symptoms come drives the decision more than anything else. Daily symptoms point to a Holter. Weekly or monthly symptoms point to extended monitoring. Symptoms a few times a year may justify an implanted recorder. How bad the symptoms are raises the stakes. Brief flutters are a nuisance. Fainting without warning is a safety issue, above all while driving or on stairs. It justifies longer and firmer monitoring sooner. The clinical question also matters. Say you have known arrhythmias and want to check whether a medicine controls your rate. A short continuous recording is ideal for that. If the goal is proving that atrial fibrillation exists at all, longer monitoring finds many more episodes. Stroke history changes the threshold. After a stroke with no known cause, long monitoring is standard. Finding atrial fibrillation switches treatment from antiplatelet drugs to blood thinners. Blood thinners are hard for some people to tolerate. Our left atrial appendage closure vs blood thinners page covers what comes next. Structure is a separate question. Rhythm monitors say nothing about valves or pump function. That is why an ultrasound is often ordered alongside. See echocardiogram vs EKG. Practical fit counts too. Sensitive skin, job demands, and comfort with technology all shape which device you will actually wear for the full period. Questions to ask your cardiologist - How long should the recording run to give a real chance of catching my symptoms? - If this monitor comes back normal, what does that rule out and what does it not? - Does this device detect abnormal rhythms on its own, or only when I press the button? - Can I shower, exercise, and sleep normally while wearing it? - Who reviews the recording, and when should I expect results? - If nothing is captured, what is the next step?

Dr Vimal Nanavati explains what the evidence shows for stable and unstable disease, in San Diego and Redding, CA. The short answer It depends almost entirely on one thing: whether your disease is stable or unstable. During a heart attack, or with unstable chest pain, opening the blocked artery with a stent saves heart muscle. It saves lives. There is no serious debate there. Stable disease is a different picture. Stable means predictable chest pressure that comes with effort and settles with rest. Large randomized trials have found that adding a stent to good medication does not reduce the risk of death or future heart attack for most patients. What a stent does reliably do in stable disease is relieve symptoms. It often does that faster and more fully than pills. So the honest framing is not which option is better. It is what you are trying to achieve. If the goal is living longer, medicine and risk factor control do the heavy lifting. If the goal is walking uphill without chest pain, a stent may be worth it. How they differ at a glance | | Coronary stent | Medical therapy | | --- | --- | --- | | What it involves | A catheter opens the narrowing with a balloon. It leaves a drug coated mesh scaffold in the artery. | Daily medicines: a statin, aspirin, blood pressure control, and antianginal drugs such as beta blockers or nitrates. | | Where it is done | Hospital cardiac catheterization lab. Dr. Nanavati performs these at affiliated hospitals. | At home, guided by office visits, lab work, and periodic testing. | | Anesthesia or sedation | Local anesthetic at the wrist or groin plus light conscious sedation. | None. | | Typical recovery | Same day discharge or one night. Light activity within days. Dual antiplatelet pills for months afterward. | No recovery period. Dose changes and side effect checks over the first few months. | | Best suited for | Heart attack, unstable symptoms, left main or high risk anatomy, or angina that persists despite good medication. | Stable angina, mild to moderate narrowings, and every patient with coronary disease, including those who also get a stent. | Stenting in detail A coronary stent goes in during angioplasty. That is the catheter procedure also known as PTCA. The balloon presses plaque against the artery wall. The stent then holds the channel open so it does not spring shut. In an emergency the benefit is large and immediate. When a coronary artery closes completely, heart muscle starts dying within minutes. Prompt catheter treatment limits that damage. MedlinePlus describes this as the preferred emergency approach. In stable disease the benefit is symptom relief, not longer life. That is still worth a lot. Angina that stops you climbing stairs or working in the yard is a real loss of life quality. A stent often fixes that quickly. A stent also carries duties. You will take two antiplatelet medicines for a period your cardiologist sets. Stopping them early risks a clot inside the stent. The stent treats one segment of one artery. It does nothing for plaque elsewhere. That is why medicine continues either way. Medical therapy in detail Optimal medical therapy is not a placeholder while you wait for a procedure. It is the treatment that changes the course of coronary artery disease. A high intensity statin lowers LDL cholesterol. It also steadies plaque so it is less likely to rupture. Aspirin reduces clotting. Blood pressure control lowers strain on the arteries. Beta blockers, calcium channel blockers, and long acting nitrates cut how often angina appears. Diabetes control, quitting smoking, and steady exercise through cardiac rehabilitation all add measurable benefit. The NHLBI guidance on coronary heart disease and the CDC both put these steps at the center of treatment. The drawback is patience. Pills work slowly, and doses need adjusting. Side effects such as fatigue or muscle aches take time to sort out. Some patients keep having angina on a full drug regimen. That group is exactly where stenting earns its place. How Dr. Nanavati decides which is right for you The first question is urgency. Chest pain at rest, pain that is new and getting worse, or an abnormal troponin blood test all call for an urgent catheter strategy. A trial of pills is not the answer then. Details are on our chest pain page. For stable symptoms, the next question is how much heart muscle is at risk. A nuclear stress test or other advanced stress testing shows how large an area is short of blood. A small area argues for medicine. A large area raises concern, and so does a drop in blood pressure during exercise. Location matters. A major left main narrowing is treated differently from a spot in the middle of a vessel. So is severe disease at the start of the left anterior descending artery. Multi vessel disease may point toward surgery instead. Our angioplasty vs bypass surgery page covers that choice. How you respond to medicine is the practical test. Many patients improve a great deal once the doses are right. The stent conversation then quietly ends. Bleeding risk is the counterweight. If you cannot safely take dual antiplatelet therapy, a stent becomes riskier. Guideline frameworks from the American College of Cardiology weigh that explicitly. Your own priorities count. Some patients accept daily pills to avoid a procedure. Others want the fastest route back to activity. Both are reasonable. Questions to ask your cardiologist - Is my coronary disease stable right now, or is this an unstable situation? - How much heart muscle is at risk based on my stress test or imaging? - Would a stent here improve my survival, or mainly my symptoms? - Have my medicines been pushed to full doses before we consider a procedure? - How long would I need dual antiplatelet therapy, and is my bleeding risk acceptable? - If I choose medicine first, what specific symptoms should make me call you?

Dr Vimal Nanavati compares transradial and transfemoral angiograms, in San Diego and Redding, CA. The short answer These are two routes to the same destination. In both, a thin catheter is guided to the openings of the coronary arteries. Dye is then injected and the arteries are filmed. The difference is where the catheter goes in. Transradial access starts at the radial artery in the wrist. Transfemoral access starts at the femoral artery in the groin. For most routine coronary angiograms today, the wrist is the preferred first choice. It bleeds less, and it lets you sit up and walk sooner. Patients generally find it more comfortable. The groin still has clear roles. It gives a larger, straighter vessel. That matters for bulky equipment, complex blockages, structural heart procedures, and peripheral artery work. The groin is also the fallback when a wrist artery is too small, already used, or hard to navigate. Your arteries, and what the procedure needs to do, decide the route. How they differ at a glance | | Transradial (wrist) | Transfemoral (groin) | | --- | --- | --- | | What it involves | A sheath is placed in the radial artery at the wrist. Catheters travel up the arm and across the aortic arch to the heart. | A sheath is placed in the femoral artery in the groin. Catheters travel up the aorta to the heart. | | Where it is done | Hospital cardiac catheterization lab. Dr. Nanavati performs these at affiliated hospitals. | Hospital cardiac catheterization lab, same setting and same imaging equipment. | | Anesthesia or sedation | Local anesthetic at the wrist plus light conscious sedation. A medication is given to prevent artery spasm. | Local anesthetic at the groin plus light conscious sedation. You remain awake and responsive. | | Typical recovery | A compression band on the wrist for one to two hours. You can usually sit up and walk almost right away. | Two to six hours lying flat while the puncture seals. Avoid lifting and straining for several days. | | Best suited for | Routine diagnostic angiography, most stenting, patients at higher bleeding risk, and those who cannot lie flat. | Large bore equipment, complex or calcified blockages, structural heart procedures, and unsuitable wrist anatomy. | Transradial angiography in detail A transradial angiogram uses an artery that sits just under the skin, right over bone. That anatomy is the whole advantage. If bleeding starts, a band pressed against the wrist stops it easily. Any bruising shows up at once, rather than hiding deep in the pelvis. The result is fewer serious problems at the access site. Randomized trials, reflected in American College of Cardiology guideline resources, support radial access as the default in acute coronary syndromes. Less bleeding there has been linked to better outcomes. Recovery is easier too. Lying flat for hours is hard for patients with back pain, heart failure, or breathing trouble. The wrist route avoids that entirely. The limits are physical. The radial artery is small, so very large catheters may not fit. It can go into spasm, which makes the forearm ache during the procedure. The path through the arm and shoulder winds more. So unusual anatomy sometimes forces a switch to the groin partway through. A small share of radial arteries close off afterward. That usually causes no symptoms, because the hand has a second blood supply through the ulnar artery. Transfemoral angiography in detail A transfemoral angiogram uses a much larger vessel. The route to the heart is shorter and straighter. Catheter control is therefore steadier, which is why it remains standard for demanding cases. Some procedures all but require it. Large bore devices, mechanical circulatory support, valve procedures, and many peripheral vascular interventions need a vessel the wrist cannot supply. Complex coronary work often benefits from the extra support of the groin route. That includes chronic total occlusions, and heavily calcified lesions treated with atherectomy. The tradeoff is bleeding risk and recovery. The artery lies deep, so a bleed can collect out of sight before anyone sees it. Problems at the access site are more common than with wrist access. Lying flat afterward is the price of a safe seal. Closure devices can shorten that time, but you still need a period of observation. The American Heart Association and the National Heart, Lung, and Blood Institute describe cardiac catheterization and its risks in more detail. How Dr. Nanavati decides which is right for you Checking your pulse comes first. Both wrist arteries are examined, and blood flow to the hand is checked before the wrist route is chosen. What the procedure is for matters next. A diagnostic study suits the wrist well. So does a straightforward angioplasty with coronary stenting. Expected complexity shifts the balance toward the groin. Bleeding risk is weighted heavily. Anticoagulant medicine, low platelet counts, obesity, and older age all favor the wrist. Bleeding there is easier to see and control. Your history counts. Three things rule out an arm: an earlier radial catheterization, a dialysis fistula, or a plan to use that radial artery as a bypass graft. Past bypass surgery with certain grafts sometimes favors the groin, for reach. Body shape and comfort matter. Patients who cannot lie flat do far better with wrist access. So do those with severe back or hip problems. Finally, plans change mid procedure. If the anatomy will not cooperate, switching routes is routine. It is not a complication. The purpose is a complete, safe study of your coronary artery disease. Our angioplasty vs bypass surgery page covers how the treatment decision follows. Still deciding whether an invasive study is needed at all? See CT angiography vs invasive angiogram. Questions to ask your cardiologist - Which access site do you plan to use for my procedure, and why that one? - Has the circulation to my hand been checked before choosing the wrist? - Given my medicines, which route carries less bleeding risk for me? - How long will I need to stay still afterward, and when can I go home? - If a stent is needed, does the planned access site still work? - What would make you switch from one site to the other during the procedure?

Dr Vimal Nanavati explains accuracy, radiation and who needs imaging, at HeartCare4life in San Diego and Redding, CA. The short answer A plain treadmill test and a nuclear stress test look for the same thing. Both hunt for coronary artery blockages that only show up when the heart works hard. The difference is whether pictures are taken. In a treadmill test, the data are your EKG tracing, your blood pressure, your symptoms, and how long you last. In a nuclear study, a small amount of radioactive tracer is injected. A camera then photographs blood flow in the heart muscle at rest and at peak stress. The treadmill test is simpler, cheaper, and free of radiation. It is perfectly adequate for many patients who walk well and have a normal resting EKG. The nuclear study is more accurate. It shows exactly which wall of the heart is short of blood, which matters when the stakes are higher. Your ability to exercise and your baseline EKG usually decide which one you need. How they differ at a glance | | Treadmill exercise stress test | Nuclear stress test | | --- | --- | --- | | What it involves | You walk on a treadmill at rising speed and incline. EKG, blood pressure, and symptoms are recorded throughout. | A radioactive tracer is injected through an IV. A camera images blood flow at rest and at peak stress, with exercise or medication. | | Where it is done | In the office at HeartCare4life, with a physician present throughout. | A nuclear imaging suite, because a gamma camera and licensed tracer handling are required. | | Anesthesia or sedation | None. | None. If you cannot walk, a medication such as regadenoson or dobutamine simulates exertion. | | Typical recovery | None. Roughly 30 to 45 minutes total, then you drive yourself home. | None, but plan on two to four hours because of rest and stress imaging sets. Drink fluids afterward. | | Best suited for | Patients who can walk on a treadmill and have a readable resting EKG. | Patients who cannot exercise, have an abnormal baseline EKG, or need the location and size of ischemia measured. | Treadmill stress testing in detail The treadmill stress test follows a staged protocol. Speed and slope increase every three minutes. You continue until you reach a target heart rate, develop symptoms, or ask to stop. It measures more than the EKG. How far you can walk is one of the strongest predictors of heart outcomes. Your blood pressure response carries information too. So does how fast your heart rate settles afterward, and whether chest pain appears. The American Heart Association explains what is being watched. The weakness is in reading the result. The test compares your exercise EKG with your resting one. Some resting tracings cannot support that comparison. Examples are left bundle branch block, a paced rhythm, marked left ventricular thickening with repolarization changes, and certain medication effects. The exercise EKG cannot then be read reliably, so a picture based test is needed instead. False positives are also more common in women, and in patients with resting ST segment abnormalities. That sometimes leads to follow up testing you did not need. Nuclear stress testing in detail A nuclear stress test compares blood delivery to the heart muscle in two states. It is sometimes called myocardial perfusion imaging. Muscle fed by a narrowed artery takes up less tracer at peak stress than at rest. That difference shows up as a defect on the images. This adds three things a treadmill test cannot give you. It pins the problem to the area fed by one artery. It estimates how much muscle is affected, which weighs heavily on whether a procedure is worthwhile. And it tells reversible ischemia apart from fixed scar left by an old heart attack. The National Heart, Lung, and Blood Institute outlines both formats. Perhaps you cannot walk far because of arthritis, lung disease, or being out of shape. A medicine can then widen the coronary arteries or raise the heart rate instead. That option is part of our advanced stress testing program. The tradeoffs are time, cost, and a radiation dose. You must avoid caffeine beforehand when a vasodilator drug is used, because caffeine blocks it. How Dr. Nanavati decides which is right for you Can you exercise? This is the first and most important question. Walking gives information that no drug can copy. So exercise is preferred whenever possible. Is your baseline EKG readable? An abnormal resting tracing pushes the decision toward imaging, no matter how well you walk. How likely is disease? Say the odds of coronary artery disease are low and you walk normally. The treadmill test is often enough then. Higher odds favor imaging, because a normal treadmill result would not be reassuring enough. What will the result change? Say you already have known blockages or earlier stents. The useful question is then how much muscle is at risk, and that takes imaging. Sometimes the arteries themselves are the better target. When the question is what they look like, not how they perform, our CT angiography vs invasive angiogram comparison covers those options. And when the worry is structure or rhythm rather than blood flow, see echocardiogram vs EKG. Your symptom pattern also guides urgency. Chest pain at rest is not a stress test situation. It needs prompt evaluation. Questions to ask your cardiologist - Is my resting EKG normal enough for a plain treadmill test to be readable? - Can I walk far enough to reach a diagnostic heart rate? - If imaging is added, how much radiation is involved and is that justified here? - Would a stress echocardiogram give the same answer without radiation? - What would an abnormal result actually change about my treatment? - Should I hold any medicines or avoid caffeine before the test?

Dr Vimal Nanavati compares recovery and results, at HeartCare4life in San Diego and Redding, CA. The short answer Both procedures treat the same problem. A leg vein has one way valves, and those valves have failed. So blood pools instead of returning to the heart. Vein stripping is the older surgical answer. The surgeon makes cuts at the groin and lower leg, then pulls the faulty vein out. Venous ablation is the catheter based answer. A thin fiber or catheter goes inside the vein, guided by ultrasound. The vein is then sealed shut from within, using heat, a medical adhesive, or a chemical agent. Your body reroutes the blood through healthy deeper veins. For most people with reflux in the great or small saphenous vein, ablation has become the preferred first approach. Results are comparable, while pain, bruising, and time away from work are substantially lower. Stripping remains useful for particular anatomy. And for many patients, compression and conservative care should come first. How they differ at a glance | | Venous ablation | Vein stripping | | --- | --- | --- | | What it involves | A catheter or fiber goes inside the vein through a needle puncture. Heat, adhesive, or a sclerosing agent seals the vein closed. | The vein is tied off and physically removed through incisions at the groin and lower leg. | | Where it is done | In the office procedure room, guided by ultrasound. No hospital stay. | A hospital or surgical center operating room, performed by a vascular or general surgeon. | | Anesthesia or sedation | Local anesthetic, usually with dilute tumescent anesthesia along the vein. You stay awake. | General or spinal anesthesia in most cases. | | Typical recovery | Walking immediately. Compression stockings for a period afterward. Most people return to desk work within a day or two. | One to three weeks before normal activity. More bruising, more soreness, and incisions that need wound care. | | Best suited for | Saphenous vein reflux with suitable vein size and a reasonably straight course. | Very large, tortuous, or aneurysmal veins, veins lying very close to the skin, and some recurrent cases after prior treatment. | Venous ablation in detail Venous ablation closes the diseased vein rather than removing it. Once sealed, the vein slowly shrinks into a fibrous cord and is absorbed. Blood that used to pool there returns through the deep veins. Those deep veins carry the great majority of leg blood flow anyway. Heat based methods use radiofrequency energy or laser light. They need tumescent anesthesia. That is a watery numbing solution injected around the vein. It numbs the vein and shields nearby nerves and skin. Methods without heat use a medical adhesive or a chemical agent, and need less injected numbing medicine. The advantages hold up across studies. There is less pain afterward, less bruising, a faster return to work, and fewer wound problems. Closure rates and symptom relief are comparable to surgery. The National Heart, Lung, and Blood Institute describes these minimally invasive options alongside traditional surgery. Ablation has limits. It treats the leaking trunk vein underneath. The visible surface veins often need more treatment, such as sclerotherapy or a small phlebectomy. Possible problems include skin staining along the treated vein, and short lived nerve irritation that causes numbness. Rarely, a clot spreads toward the deep veins. That is why a follow up ultrasound is standard. Vein stripping in detail Vein stripping and high ligation ruled varicose vein treatment for most of the twentieth century. And it works. The leaking vein is cut free where it joins the deep system. It is then removed along its length. The vein is physically gone, so it cannot reopen. A sealed vein does reopen in part now and then. Surgeons still choose stripping for veins that are unusually wide, badly twisted, or ballooned out. They also choose it for veins so close to the skin that heating them would risk a burn. It is considered as well when varicose veins come back after earlier procedures. The costs are real. General or spinal anesthesia carries its own risks. Recovery brings more pain and bruising. The cuts need care, and the return to work takes longer. Wound infection and saphenous nerve injury are recognized complications. Plain explanations of both treatment routes are available from MedlinePlus. Stripping is performed by surgeons. Dr. Nanavati checks the veins and performs office based ablation when it fits. When an operation is the better answer, he refers to a surgeon and coordinates the care. How Dr. Nanavati decides which is right for you Everything starts with a map. A venous ultrasound shows which veins are leaking, how large they are, and how deep they run. It also shows whether any clot is present. Treating varicose veins without that study is guesswork. Conservative care comes first for most patients. Graduated compression stockings, raising the legs, weight control, and walking often settle aching, heaviness, and swelling. A trial of that is reasonable before any procedure. For some people it is the whole treatment. Symptoms have to justify treatment. Aching, throbbing, night cramps, swelling, thickened skin, and healed or open ulcers near the ankle are medical findings. Appearance alone is a different conversation. Anatomy then narrows the options. Vein width, twisting, depth under the skin, and nearness to nerves all shape whether ablation will work well and safely. Other causes must be ruled out. Leg swelling can come from heart failure, kidney disease, or the lymph system rather than the veins. When the heart is suspected, an office echocardiogram helps sort it out. Clot history changes the plan. A past deep vein thrombosis changes how the deep system works, and treatment has to account for that. Background on venous clotting is available from the American Heart Association and MedlinePlus. Not sure who should check your legs in the first place? See our cardiologist vs interventional cardiologist comparison. Questions to ask your cardiologist - Does my ultrasound actually show reflux, and in which specific veins? - Are my symptoms medical, or is my main concern the appearance of the veins? - Have I given compression therapy a fair trial first? - Is my vein a good candidate for ablation, or does its size or course argue for surgery? - Will I need more treatment for the surface veins after the main vein is treated? - What follow up imaging is done afterward, and what would it be checking for? Talk it through with a cardiologist Dr. Vimal Nanavati, MD, FACC is board certified in cardiology and interventional cardiology, with 32 years in practice. He founded HeartCare4life in 1997.

Dr Vimal Nanavati explains who qualifies, at HeartCare4life in San Diego and Redding, Calif. The short answer For most people with atrial fibrillation who need stroke protection, a blood thinner is the first choice. And it should stay the first choice. Blood thinners, also called anticoagulants, have decades of randomized trial evidence behind them. They also protect against clots wherever those clots form. Left atrial appendage closure is a catheter procedure. It seals off a small pouch on the left atrium. Most atrial fibrillation clots start in that pouch. The best known device is called the Watchman. Closure is not a general purpose replacement for blood thinners. It exists mainly for patients who have a real reason they cannot stay on them long term. Examples are repeated serious bleeding, a bleeding condition that cannot be fixed, or a high risk of falls with head injury. If you tolerate your blood thinner well, closure usually offers no advantage. If you truly cannot take one, closure gives you a stroke prevention option you would otherwise not have. How they differ at a glance | | Left atrial appendage closure | Anticoagulant medication | | --- | --- | --- | | What it involves | A catheter passes from a leg vein into the right atrium. It crosses to the left atrium and places a small device that seals the appendage. | A daily pill, either a direct oral anticoagulant such as apixaban or rivaroxaban, or warfarin with regular blood testing. | | Where it is done | Hospital catheterization lab, with ultrasound imaging from inside the esophagus or the heart to guide placement. | At home, with office follow up and periodic lab work. | | Anesthesia or sedation | General anesthesia or deep sedation, because a swallowed ultrasound probe is usually used for guidance. | None. | | Typical recovery | Usually one overnight stay. Light activity within days. Follow up imaging at about 45 days confirms the seal. | No recovery period. Ongoing checks for bleeding, and dose changes for kidney function or interactions. | | Best suited for | Non valvular atrial fibrillation in patients who cannot safely stay on long term anticoagulation. | Nearly all patients with atrial fibrillation and elevated stroke risk who can tolerate the medication. | Anticoagulant medication in detail In atrial fibrillation, the upper chambers quiver instead of squeezing. Blood then moves sluggishly, and clots can form. If a clot travels to the brain, it causes a stroke. Blood thinners cut that risk sharply, and they remain the foundation of treatment. The National Heart, Lung, and Blood Institute and the American Heart Association both call this standard care for patients above a set level of stroke risk. Direct oral anticoagulants have made things much simpler. They need no routine blood testing. They clash with fewer foods than warfarin does. Several have also shown lower rates of bleeding inside the brain. Warfarin is still needed for mechanical heart valves, and for moderate to severe mitral stenosis. The newer drugs are not appropriate there. The real drawback is bleeding. Any blood thinner that works raises bleeding risk somewhere. Three situations most often make it impossible to continue. They are repeated bleeding in the gut, past bleeding into the brain, and frequent falls. Practical guidance for patients is available from MedlinePlus. Taking the pills as prescribed also matters. These medicines protect only while they are in your system. Missed doses leave you unprotected. Left atrial appendage closure in detail Left atrial appendage closure treats the anatomy rather than the blood. The appendage is a small pouch off the left atrium. It has no known essential job. In non valvular atrial fibrillation, it is the source of the large majority of clots that cause stroke. Sealing it removes that reservoir. The procedure goes through a vein in the leg. No artery is punctured, and no chest cut is made. Imaging guides the device into the mouth of the appendage. There it expands and stays for good. Being honest about the caveats matters here. Closure does not treat atrial fibrillation itself. Your rhythm, your heart rate, and your symptoms stay the same. It does not remove stroke risk, since clots can form elsewhere. You will still need some clot preventing medicine for a period after the device goes in, while tissue grows over it. So it is not an immediate exit from all blood thinners. The procedure also carries its own risks. They include fluid collecting around the heart, the device moving, a clot forming on its surface, and leaks around the edges. Trial evidence supports closure as an alternative in appropriate patients. That is why it appears in the American College of Cardiology guideline resources. But it is an option for a specific group, not a general upgrade. How Dr. Nanavati decides which is right for you Stroke risk is worked out first. Scoring systems weigh age, sex, heart failure, high blood pressure, diabetes, vascular disease, and past stroke. If your calculated risk is low, neither option may be needed. Bleeding history decides it for most candidates. Some findings move closure onto the table. They include a documented major bleed on a blood thinner, past bleeding in the brain, a bleeding disorder, or repeated gut bleeding that cannot be fixed. Next, can the problem be solved another way? Sometimes bleeding comes from an ulcer or polyp that can be treated. Sometimes another drug, or too high a dose, is to blame. Fixing that beats giving up the blood thinner. Anatomy has to cooperate. The appendage must be a shape and size the device can seal. No clot can already be sitting in it. Imaging confirms this before scheduling. The basic check starts with an office echocardiogram. Confirming the rhythm matters too. If atrial fibrillation is suspected but not proven, longer rhythm recording comes first. Our Holter vs event monitor page and the arrhythmias page explain those tools. Holter monitoring is performed in the office. Your values count. Some patients accept a daily pill readily. Others, after a serious bleed, will not restart one under any circumstances. The CDC outlines what is at stake on the stroke side of that decision. Questions to ask your cardiologist - What is my calculated stroke risk, and what is my calculated bleeding risk? - Is there a correctable reason for my bleeding before we abandon anticoagulation? - Would a different blood thinner, or a dose change, solve the problem? - If I have the appendage closed, what medicine will I still need, and for how long? - What are the specific risks in my case, and what does follow up imaging involve? - Does closure change anything about my heart rhythm or my other medicines?

It works around the clock pumping blood to various parts of the body through the network of blood vessels. The normal adult heart weighs between 200- 425 grams (7 to 15 ounces) and is about the size of your fist. Learning about your heart and its functions can help you understand the various conditions that may affect your heart as well to take precautions to prevent them. Know More - ## Arrhythmias Arrhythmia is a disorder characterized by abnormal heartbeat such as beating too fast, too slow or irregularly. During an arrhythmia, as the heart is not able to pump enough blood to the body, it can lead to organ dysfunction or damage. Most arrhythmias are harmless, however, some are more serious and life-threatening. Know More - ## Atrial Fibrillation Atrial fibrillation (AF) is a heart condition characterized by an irregular and rapid heartbeat that hampers blood supply to the body. In atrial fibrillation, the upper chambers (atria) and the lower chambers (ventricles) of the heart lack coordination, causing a rapid and irregular heart rhythm. People with atrial fibrillation may experience palpitations, shortness of breath, and fatigue or lack of energy. Know More - ## Coronary Artery Disease Coronary artery disease (CAD) usually occurs when cholesterol and plaque accumulate inside the coronary arteries (blood vessels supplying oxygen-rich blood to heart muscles) and block the flow of oxygen-rich blood to the heart muscles. The plaque can sometimes break off and form a blood clot that can completely block the vessels, leading to permanent heart damage. Know More - ## Aortic Aneurysm Aortic aneurysm is a condition characterized by an abnormal bulging of a section of the large blood vessel called the aorta. The aorta is the major blood vessel that carries oxygenated blood from the heart to the different parts of the body. Know More - ## Chest Pain Chest pain can present as a sharp, stabbing pain or a dull ache accompanied by discomfort in your chest. It is not a disease, but a symptom of an underlying heart problem like coronary heart disease. The degree of chest pain depends on the intensity, duration and person. Know More - ## Ventricular Arrhythmias Ventricular arrhythmias are abnormal heart rhythms that originate in the ventricles, the lower chambers of the heart. These arrhythmias can disrupt the heart’s ability to pump blood effectively, potentially leading to serious complications, including cardiac arrest. An arrhythmia happens when there is an issue with the electrical system of the heart that is supposed to maintain a stable heartbeat. With an impaired electrical system, your heart may beat too slow, too fast, or irregularly. Know More - ## Heart Murmur A heart murmur is a swishing or whooshing sound produced by your heart due to abnormal or turbulent blood flow in or near your heart. It may occur due to a defect in your heart valves or any condition that causes your heart to pump more blood than normal. Your doctor can detect a heart murmur with the help of a stethoscope. It is heard as an extra sound other than the usual ‘lub-dup’ sounds caused due to the closing of heart valves during normal blood circulation. Know More - ## Ventricular Tachycardia Ventricular tachycardia, also called V-tach or VT, is a fast, abnormal heart rhythm (arrhythmia) that originates in the ventricles (the lower chambers of the heart). It is characterized by a heart rate of 100 beats per minute or more and can be life-threatening if sustained or if it deteriorates into ventricular fibrillation, leading to cardiac arrest. Know More - ## Heart Palpitations Heart palpitations refer to the unusual sensations that feel like your heart is beating abnormally. They may be felt like an accelerated heartbeat, a flutter or a missed heartbeat. The common sites for experiencing symptoms of heart palpitations are the chest, neck or throat.

What is an aortic aneurysm? An aortic aneurysm is a bulge in the wall of the aorta. The aorta is the large artery that carries blood from your heart to the rest of your body. One section of the artery wall weakens and stretches outward. It looks a little like a worn spot on a garden hose. Aneurysms are named for where they sit. A thoracic aortic aneurysm forms in the chest. An abdominal aortic aneurysm, often shortened to AAA, forms in the belly. Most grow slowly and cause no symptoms. Many are found by accident on a scan ordered for something else. The concern is that a large aneurysm can tear or burst. That is a life threatening emergency. Size predicts that risk. So cardiologists measure a known aneurysm on a schedule. They also control the blood pressure and cholesterol that drive it. Smoking, older age, high blood pressure and a family history raise risk the most, according to the National Heart, Lung, and Blood Institute. Symptoms to watch for Most aortic aneurysms are silent. When symptoms do appear, they are often vague and easy to dismiss. Call the office if you notice any of these: - A deep, steady ache in your belly, side or lower back that does not go away. - A pulsing or throbbing feeling near your navel. - Dull pain in the chest or upper back. - Hoarseness, a new cough or trouble swallowing, which a chest aneurysm can cause by pressing on nearby structures. Call 911 immediately if you have any of the following. These can mean the aneurysm is tearing or has burst: - Sudden, severe, ripping or tearing pain in the chest, back or abdomen. - Pain with sweating, clammy skin, fainting or near fainting. - A racing pulse with sudden weakness, confusion or shortness of breath. A ruptured aneurysm is a true emergency. Do not drive yourself. The American Heart Association stresses that survival depends on how fast treatment begins. How Dr. Nanavati diagnoses it Diagnosis starts with a history and a careful exam. Imaging then measures the aorta in millimeters. That measurement drives every decision that follows. - Vascular ultrasound is the usual first test for an abdominal aortic aneurysm. It uses sound waves, takes minutes and involves no radiation or dye. - Arterial ultrasound looks at the arteries beyond the aorta. Aneurysm disease and blockage often travel together. - Transthoracic echocardiography images the heart and the first portion of the aorta as it leaves the chest. - Transesophageal echocardiography gives a more detailed look at the thoracic aorta. It is used when the standard echocardiogram view is limited. - CT angiography of the aorta provides precise cross sectional measurements of the chest and abdominal aorta. This is a different scan from the coronary CT angiography used to image the heart arteries. A hospital imaging department arranges it. - Ankle brachial index testing screens for peripheral artery disease, which is common in the same patients. - Advanced lipid testing clarifies cholesterol risk beyond a standard panel. Echocardiography, vascular ultrasound and ABI testing are all performed in the office. See the full list of cardiology services available at each location. Treatment options Small aneurysms are usually watched, not operated on. The plan has three layers. Surveillance. Dr. Nanavati sets an imaging interval once an aneurysm is measured. That interval reflects its size and how fast it has changed. Keeping those appointments is the single most important thing you can do. Risk factor control. Quitting smoking matters more here than in almost any other heart condition. Blood pressure control lowers stress on the weakened wall. The American Heart Association recommends treating elevated readings with both lifestyle and medication. Statin therapy and diet changes follow the same logic used for coronary artery disease. Cardiac rehabilitation can help you exercise safely if you also have heart disease. Medication. Blood pressure medicines such as beta blockers and ACE inhibitors are common. Cholesterol medicines are added when lipid testing supports it. Repair. Repair is recommended when an aneurysm reaches a threshold size, grows quickly or causes symptoms. That happens at an affiliated hospital. It is either open surgery or an endovascular repair through a small groin artery puncture. Dr. Nanavati coordinates the referral, the pre procedure workup and your follow up care. What to expect at your visit Bring a full list of your medications and doses. Also bring any prior imaging reports or discs and the name of your primary care physician. Your visit includes a discussion of symptoms and family history. It also includes a physical exam, blood pressure in both arms and an electrocardiogram when indicated. An ordered ultrasound is usually done in the office. For an abdominal study you may be asked not to eat beforehand, and the office will tell you when you schedule. You will leave knowing the measurement and what it means. You will also know when the next scan is due and which numbers you are working to change. Questions are welcome. The FAQs page covers what most patients ask before a first appointment. When to see a cardiologist Ask for an evaluation if an aneurysm was mentioned on any scan. Ask if a parent or sibling had an aortic aneurysm. Ask if you are a current or former smoker over 65. Anyone with known coronary artery disease or unexplained chest pain should also be assessed. You can request an appointment online or call the Bonita office at (619) 585-0476.

Other Related Diseases ## Arrhythmias URL: https://www.heartcare4life.com/conditions/arrhythmias Summary: Irregular heartbeat evaluation with in-office ECG, Holter and extended rhythm monitoring from Dr. Vimal Nanavati, MD, FACC in Bonita, San Diego and Redding. What is an arrhythmia? An arrhythmia is an abnormal heart rhythm. Your heartbeat is set by an electrical signal. That signal starts in the upper chambers of the heart and travels down to the lower chambers. It tells the muscle when to squeeze. The signal can start in the wrong place, move along the wrong path or get blocked. The beat then becomes too fast, too slow or irregular. Doctors group arrhythmias by speed and origin. Tachycardia means a resting rate above 100 beats per minute. Bradycardia means a rate below 60. Premature beats are early extra beats that feel like a skip or a thud. Atrial fibrillation is the most common sustained arrhythmia, and it comes from the upper chambers. Ventricular rhythms come from the lower chambers and are more dangerous. Many arrhythmias are harmless. Others raise the risk of stroke, fainting or cardiac arrest. That is why the National Heart, Lung, and Blood Institute advises having a persistent irregular rhythm evaluated. Symptoms to watch for Some arrhythmias produce no symptoms at all and turn up on a routine tracing. When they are felt, patients describe them in a few consistent ways. Call the office to be seen if you have: - Fluttering, pounding, racing or skipping beats that keep coming back. - A pulse that feels persistently fast or unusually slow. - Shortness of breath with ordinary activity. - Unusual fatigue, lightheadedness or a brief woozy spell. - A racing heartbeat that starts and stops abruptly. Call 911 if you have: - Chest pain or pressure along with a racing or irregular heartbeat. - Fainting, or a near faint where you lost awareness. - Severe shortness of breath at rest. - Sudden weakness on one side, trouble speaking or a drooping face, which are stroke warning signs. If someone collapses and is not breathing normally, call 911 and start CPR. The American Heart Association notes that immediate CPR can double or triple survival from cardiac arrest. How Dr. Nanavati diagnoses it Rhythm problems are intermittent. The goal is to record your heart during a symptom. Dr. Nanavati selects the monitor that matches how often your symptoms occur. - Electrocardiogram (ECG or EKG) takes about ten seconds and captures the rhythm at that moment. It is done in the office at the first visit. - Holter monitoring records every beat for 24 to 48 hours. That suits daily symptoms. - 7 to 10 day ambulatory rhythm monitoring covers symptoms that come only a few times a week. - Loop recorder implantation and interrogation uses a small device under the skin for rare events or unexplained fainting. It can watch for years. - Echocardiogram shows the pumping strength and valves. A weak or thickened heart muscle can drive arrhythmias. - Treadmill stress testing reveals rhythms that appear only with exertion. Advanced stress testing is used when a plain treadmill study is not enough. - Pacemaker interrogation and defibrillator interrogation download stored rhythm data if you already have a device. - Advanced lipid testing and blood work help identify contributing causes such as thyroid or cholesterol problems. Treatment options Treatment depends on the type of arrhythmia, your symptoms and your stroke risk. Many patients need only the first step. Lifestyle. Caffeine, alcohol, stimulants, decongestants and poor sleep all trigger extra beats. Treating sleep apnea often reduces episodes on its own. So does treating untreated high blood pressure. The habits in Life's Essential 8 apply here directly. Medication. Beta blockers and calcium channel blockers slow a fast rate. Antiarrhythmic drugs help hold a normal rhythm. An anticoagulant may be recommended if you have atrial fibrillation. It lowers stroke risk, following current American College of Cardiology guidelines. Procedures. Cardioversion resets a fast rhythm. Catheter ablation treats the tissue causing it. A pacemaker corrects a rhythm that is too slow. An implantable defibrillator protects against dangerous ventricular arrhythmias. A temporary pacemaker may be used in urgent situations. Some patients with atrial fibrillation cannot stay on blood thinners. For them, left atrial appendage closure is an alternative. Procedures are performed at affiliated hospitals. Your evaluation and follow up are handled in the office. What to expect at your visit Bring your medication list, including supplements and over the counter cold remedies. Note when your episodes happen, how long they last and what you were doing. Recordings from a smart watch are useful, so bring them. Your visit includes an exam, a blood pressure check and an ECG. Staff place any ordered monitor before you leave. They also explain how to mark symptoms. When the recording is read, you get a plain language explanation of what your heart was doing and what happens next. Common questions are answered on the FAQs page. When to see a cardiologist See a cardiologist for repeated palpitations or a persistently irregular pulse. Unexplained fainting is another reason. So are palpitations with chest pain or breathlessness. A family history of sudden cardiac death deserves prompt evaluation. Request an appointment online or call the Bonita office at (619) 585-0476.

Other Related Diseases ## Atrial Fibrillation URL: https://www.heartcare4life.com/conditions/atrial-fibrillation Summary: Atrial fibrillation diagnosis, stroke risk assessment and treatment from Dr. Vimal Nanavati, MD, FACC at HeartCare4life in Bonita, San Diego and Redding, CA. What is atrial fibrillation? Atrial fibrillation is an irregular and often rapid heart rhythm. It begins in the two upper chambers of the heart. Most people call it AFib or AF. The upper chambers quiver instead of squeezing in a steady, coordinated way. Blood is still pumped, but less efficiently. The lower chambers respond at an uneven pace. That is why the pulse feels chaotic. AFib may come in short bursts that stop on their own. It may also become the heart's everyday rhythm. Some people feel every episode. Others feel nothing and learn about it during a routine exam. The most important consequence is stroke. Blood can pool while the upper chambers quiver. A clot then forms and travels to the brain. The National Heart, Lung, and Blood Institute identifies AFib as a major stroke risk factor. AFib is also treatable, and treatment lowers that risk substantially. Symptoms to watch for AFib feels different from person to person. Roughly a third of patients have no symptoms at all. Call the office if you notice: - A fluttering, quivering or galloping heartbeat. - A pulse that is irregular when you check it at your wrist. - Shortness of breath with stairs or light activity. - Fatigue that is new or out of proportion to what you are doing. - Lightheadedness, or a feeling of pressure in the chest with an episode. Call 911 right away if you have: - Chest pain or pressure that lasts more than a few minutes. - Sudden face drooping, arm weakness or trouble speaking, the stroke warning signs. - Fainting, or severe shortness of breath at rest. Stroke symptoms are time critical. Treatment works best in the first hours. Call 911 rather than driving to a hospital. How Dr. Nanavati diagnoses it AFib has to be captured on a tracing to be confirmed. Episodes come and go. So the choice of monitor matters as much as the test itself. - Electrocardiogram (ECG or EKG) confirms AFib in seconds when you are in the rhythm during your visit. - Holter monitoring records 24 to 48 hours of beats. It suits symptoms that occur most days. - 7 to 10 day ambulatory rhythm monitoring catches episodes that appear only occasionally. It also measures how much of the time you are in AFib. - Loop recorder implantation and interrogation provides long term monitoring. It is used after a stroke of unknown cause or for very infrequent episodes. - Transthoracic echocardiography measures the size of the upper chambers. It also checks the valves and reports pumping strength. - Transesophageal echocardiography looks directly for clot in the left atrial appendage before cardioversion or ablation. - Advanced lipid testing plus thyroid and metabolic blood work identifies reversible drivers. - Treadmill stress testing shows how well your rate is controlled with exertion. Monitoring and echocardiogram studies are performed in the office at all three sites. Treatment options AFib care has two separate jobs. It prevents stroke and manages the rhythm itself. Both are addressed at every visit. Stroke prevention. Your risk is scored using age, blood pressure, diabetes, heart failure, vascular disease and prior stroke. An anticoagulant is prescribed when the score warrants it. That follows American College of Cardiology guidelines. Some patients cannot take long term blood thinners. For them, left atrial appendage closure seals the pouch where most AFib clots form. Lifestyle. Weight loss, treating sleep apnea, limiting alcohol and cutting stimulants all reduce how often AFib returns. So does controlling blood pressure. These steps are part of the American Heart Association approach. They are as effective as some medications. Rate and rhythm medication. Beta blockers and calcium channel blockers slow the heart rate. Antiarrhythmic drugs work to hold normal rhythm. Procedures. Electrical cardioversion resets the rhythm with a brief, sedated shock. Catheter ablation isolates the tissue triggering AFib. A pacemaker is added when the rate runs too slow. It is checked at follow up by pacemaker interrogation. These procedures take place at affiliated hospitals. Cardiac rehabilitation helps you rebuild activity safely afterward. What to expect at your visit Bring every medication bottle or an accurate list. Also bring any tracings from a smart watch or home device. Be ready to describe when episodes start, how long they last and what triggers them. Your appointment includes an exam, a blood pressure and pulse check and an ECG. Echocardiography and monitor placement are typically arranged the same day. You will leave with a clear answer on three points. You will know whether you need a blood thinner and how your rate will be controlled. You will also know the plan if AFib returns. The FAQs page answers common questions about preparing for a first visit. When to see a cardiologist Make an appointment if your pulse is irregular. Do the same if a watch or blood pressure cuff has flagged an irregular rhythm. Unexplained palpitations, breathlessness or fatigue are also reasons. AFib often accompanies coronary artery disease and high blood pressure, so a full cardiac assessment is worthwhile. Request an appointment online or call the Bonita office at (619) 585-0476.

Other Related Diseases ## Chest Pain URL: https://www.heartcare4life.com/conditions/chest-pain Summary: Chest pain and angina evaluation with in-office ECG, stress testing and echocardiography from Dr. Vimal Nanavati, MD, FACC in Bonita, San Diego and Redding. Call 911 now if you have chest pain with shortness of breath, sweating, nausea or vomiting. Call 911 if pain spreads to your arm, back, neck or jaw. Call 911 for chest pressure that lasts more than a few minutes, or that goes away and comes back. Do not drive yourself. Do not wait to see if it passes. These are heart attack warning signs, and treatment works best in the first minutes. Women, older adults and people with diabetes often have milder or unusual symptoms. Call anyway if something feels wrong. What is chest pain? Chest pain is any discomfort felt between the neck and the upper abdomen. It is a symptom, not a diagnosis, and it has many possible causes. The one that must be ruled out first is reduced blood flow to the heart muscle. A narrowed coronary artery starves the heart of oxygen during exertion. The result is angina: pressure, squeezing, tightness or burning that comes on with activity and eases with rest. A heart attack happens when that flow stops completely. The discomfort is then usually more intense, and it does not ease. Not all chest pain is cardiac. Acid reflux, muscle strain, rib inflammation, anxiety and pneumonia all cause it. So does inflammation of the sac around the heart. The difficulty is that these can feel alike. That is why the American Heart Association advises treating unexplained chest pain as an emergency until a clinician says otherwise. Symptoms to watch for Cardiac chest pain is more often described as pressure or heaviness than as sharp pain. Pay attention to the pattern. Call 911 immediately for: - Chest pressure, squeezing or fullness lasting more than a few minutes. - Pain radiating to the arm, shoulder, back, neck or jaw. - Chest discomfort with cold sweat, nausea, or shortness of breath. - Sudden severe pain with fainting or a feeling that something is badly wrong. Call the office to be seen soon for: - Chest tightness that reliably appears with walking or stairs and stops with rest. - Discomfort that has been happening for weeks without getting worse. - Chest pain that comes with palpitations or unusual fatigue. - Pain that is clearly reproduced by pressing on the chest wall or by certain foods. Angina that is new, more frequent or now occurring at rest is called unstable. The National Heart, Lung, and Blood Institute treats that as an emergency. How Dr. Nanavati diagnoses it The goal is to answer one question first. Is your heart muscle getting enough blood? Testing is chosen for your symptoms and risk profile. - Electrocardiogram (ECG or EKG) is performed in the office at the first visit. It shows evidence of strain or prior injury. - Treadmill stress testing records the heart while you walk. It reproduces the conditions that bring on your symptoms. - Nuclear stress testing adds imaging that shows which region of muscle is short of blood. - Advanced stress testing is used when you cannot walk a treadmill. It also helps when a standard study is inconclusive. - Echocardiogram and transthoracic echocardiography assess pumping strength, valves and the sac around the heart. - Coronary CT angiography images the coronary arteries themselves without a catheter. - Ischemic heart disease evaluation brings these findings together into one assessment. - Advanced lipid testing measures the cholesterol particles driving plaque. The non invasive results may point to a significant blockage. A transradial angiogram through the wrist then follows, or a transfemoral angiogram. Both are performed at an affiliated hospital. Treatment options Treatment follows the cause. Care moves through three levels when the cause is coronary artery disease. Lifestyle and risk factors. Stop smoking. Control your blood pressure and blood sugar, move daily and eat for heart health. These steps lower the frequency of angina. The heart healthy living guidance from NHLBI is the practical starting point. Every patient also reviews the seven risk factors for heart attack. Medication. Nitrates relieve angina. Beta blockers and calcium channel blockers reduce the heart's oxygen demand. Statins stabilize plaque. Aspirin or other antiplatelet drugs reduce clotting risk. Procedures. A severe narrowing is opened with a balloon. That is angioplasty, also called PTCA. A coronary stenting procedure then holds the artery open. Some patients are better served by bypass surgery. These are hospital based procedures. The office arranges them and follows up. Cardiac rehabilitation afterward improves stamina and lowers the chance of another event. What to expect at your visit Bring a medication list. Also bring any records from an emergency room or urgent care visit for the same pain. Be ready to describe what brings the pain on and how long it lasts. Say what relieves it and whether it has changed. Your visit includes an exam, blood pressure and an ECG. Stress testing and echocardiography are done in the office. Staff explain how to prepare, including whether to hold caffeine or a particular medication. You leave with an explanation of the likely cause and the tests being ordered. You also get clear instructions on when to call 911 in the meantime. More preparation details are on the FAQs page. When to see a cardiologist Schedule an evaluation for chest discomfort with activity. Do the same for pain that has been dismissed but keeps returning. An emergency room visit that did not find an answer is another reason. Anyone with a family history of early heart disease, diabetes, high cholesterol or aortic aneurysm should be assessed.

Other Related Diseases ## Coronary Artery Disease URL: https://www.heartcare4life.com/conditions/coronary-artery-disease Summary: Coronary artery disease testing and treatment, from stress testing to stenting, with Dr. Vimal Nanavati, MD, FACC in Bonita, San Diego and Redding, CA. What is coronary artery disease? Coronary artery disease, or CAD, is the buildup of cholesterol rich plaque inside the coronary arteries. These are the vessels that deliver oxygen rich blood to the heart muscle. Plaque forms slowly over decades. As it thickens, the channel narrows. The muscle downstream then receives less blood than it needs during exertion. That shortfall causes angina. Angina is the pressure or tightness people feel when they climb stairs or hurry. A plaque can also rupture. A clot then forms on top of it and blocks the artery completely. The result is a heart attack and permanent muscle damage. CAD is the most common form of heart disease. Heart disease remains the leading cause of death in the United States, according to the Centers for Disease Control and Prevention. The encouraging part is that CAD responds well to treatment. Cholesterol control, blood pressure control and stopping smoking all slow or halt its progression. Symptoms to watch for CAD can be present for years without a single symptom. Symptoms usually start with exertion and fade with rest. Call the office if you have: - Chest pressure, tightness or burning when you walk uphill, hurry or carry groceries. - Shortness of breath with activity you used to handle easily. - Jaw, neck, shoulder or upper back discomfort that comes on with exertion. - Unusual fatigue, or a drop in what you can do without stopping. - Nausea or lightheadedness during exercise. Call 911 immediately for: - Chest pressure lasting more than a few minutes, or that returns. - Chest discomfort with sweating, nausea, or shortness of breath. - Pain radiating into the arm, back, neck or jaw. - Sudden severe weakness, fainting or a cold sweat. Women often have less typical symptoms, such as breathlessness or extreme fatigue. The American Heart Association advises calling 911 rather than waiting for classic chest pain. How Dr. Nanavati diagnoses it Diagnosis combines your risk profile with testing. The testing shows whether the heart muscle is getting enough blood. - Electrocardiogram (ECG or EKG) is done in the office. It can reveal prior injury or ongoing strain. - Treadmill stress testing measures how your heart behaves under controlled exertion. - Nuclear stress testing shows the specific regions of muscle that are short of blood. - Advanced stress testing is used when walking is not possible. It also helps when the picture is unclear. - Echocardiogram measures pumping strength. It also finds wall segments damaged by an earlier event. - Coronary CT angiography visualizes plaque in the coronary arteries without a catheter. - Ischemic heart disease evaluation pulls the findings into a single treatment plan. - Advanced lipid testing goes beyond a routine panel to size up cholesterol risk. - Carotid ultrasound Doppler and the ankle brachial index check the neck and leg arteries for plaque. Testing sometimes suggests a significant blockage. A transradial angiogram through the wrist then provides the definitive answer at an affiliated hospital. Treatment options Every patient with CAD receives medical therapy. Procedures are added when symptoms or test results call for them. Lifestyle. Stopping smoking is the highest impact change. Regular activity and a diet low in saturated fat make up the rest. So do weight management, blood sugar control and sleep. The Life's Essential 8 framework organizes these. Your visit also covers the seven risk factors for heart attack. Medication. Most patients take more than one heart medicine. Each one has a specific job. Statins lower LDL cholesterol and stabilize plaque, following American College of Cardiology guidelines. Aspirin or another antiplatelet reduces clot risk. Beta blockers, nitrates and ACE inhibitors ease symptoms. They also protect the heart muscle. Blood pressure and diabetes medicines are adjusted alongside. Procedures. Angioplasty, also called PTCA, opens a narrowed artery with a balloon. A coronary stenting procedure props it open with a small mesh tube. Multi vessel disease may be better treated with bypass surgery. These are performed at affiliated hospitals. Cardiac rehabilitation afterward is supervised exercise and education. It measurably improves recovery. What to expect at your visit Bring your medications and recent lab results. Also bring any prior stress test, catheterization or hospital records. Expect a conversation about what you can and cannot do physically. Exercise tolerance is a key clue. The visit includes an exam, blood pressure and an ECG. Stress testing, echocardiography and lipid testing are performed in the office. Staff will tell you how to prepare, including any food, caffeine or medication instructions. You leave with your LDL target, a medication plan and a clear next step. The office explains any recommended hospital procedure and arranges the scheduling for you. Common questions are covered on the FAQs page. When to see a cardiologist See a cardiologist for exertional chest pain or declining exercise tolerance. An elevated coronary calcium score is another reason. Evaluation is also worthwhile if you have diabetes, high cholesterol or high blood pressure. The same applies if a parent or sibling had early heart disease. Request an appointment online or call the Bonita office at (619) 585-0476.

Other Related Diseases ## Heart Anatomy URL: https://www.heartcare4life.com/conditions/heart-anatomy Summary: A plain-language guide to heart anatomy and how each part can fail, with in-office testing from Dr. Vimal Nanavati, MD, FACC in San Diego and Redding, CA. How the heart works The heart is a muscular pump about the size of your fist. It sits between the lungs in the middle of the chest. It has four chambers. The two upper chambers, the atria, receive blood. The two lower chambers, the ventricles, pump it out. The right side sends oxygen poor blood to the lungs. The left side pumps oxygen rich blood to the whole body. Four valves keep blood moving in one direction. They snap shut to stop it flowing backward. The heart muscle feeds itself through the coronary arteries, which wrap around the outside. An electrical system sets the pace. It starts at the sinus node and spreads through the muscle, so the chambers squeeze in order. A healthy adult heart beats roughly 60 to 100 times a minute at rest. That range is described by the National Heart, Lung, and Blood Institute. The four chambers and four valves Blood returning from the body enters the right atrium. It passes through the tricuspid valve into the right ventricle. It then leaves through the pulmonary valve to the lungs. Oxygenated blood returns to the left atrium. It crosses the mitral valve into the left ventricle. It exits through the aortic valve into the aorta. The left ventricle is the thickest chamber because it does the hardest work. Valves fail in two ways. They can stiffen and fail to open fully, called stenosis. They can leak and let blood wash backward, called regurgitation. Either creates turbulence. A stethoscope picks that turbulence up as a heart murmur. The American Heart Association notes that valve problems are often silent for years before symptoms appear. The coronary arteries and the electrical system Two main coronary arteries branch off the aorta. They divide across the heart's surface. Plaque can narrow them. The muscle then runs short of oxygen during exertion. That is coronary artery disease, and it is the reason for exertional chest pain. The electrical system is separate. The signal starts in the sinus node. It pauses at the AV node, then spreads to the ventricles. Interruptions anywhere along that path produce arrhythmias. These include atrial fibrillation from the upper chambers and ventricular arrhythmias from the lower ones. Symptoms to watch for Knowing the anatomy makes symptoms easier to interpret. Call the office if you notice chest tightness with exertion, breathlessness climbing stairs, ankle swelling, palpitations, or fatigue that is new for you. Call 911 for chest pressure lasting more than a few minutes, chest discomfort with sweating or nausea, pain radiating to the arm or jaw, fainting, or sudden severe shortness of breath. Face drooping, arm weakness or slurred speech are stroke signs and also require 911. How Dr. Nanavati diagnoses heart problems Each structure has a test that examines it directly. - Echocardiogram and transthoracic echocardiography use ultrasound to show the chambers and the valves. They also give the ejection fraction, the percentage of blood the left ventricle pushes out with each beat. - Transesophageal echocardiography provides a closer view of the valves and upper chambers. It is used when a standard study is limited. - Electrocardiogram (ECG or EKG) maps the electrical system in about ten seconds. - Holter monitoring records the rhythm continuously for a day or two. - Treadmill stress testing and nuclear stress testing show whether the coronary arteries deliver enough blood under load. - Coronary CT angiography images the coronary arteries themselves. - Vascular ultrasound and carotid ultrasound Doppler examine the arteries beyond the heart. Echocardiography, ECG, stress testing and vascular ultrasound are all performed in the office. The complete list of cardiology services shows what is available. Treatment options Treatment is matched to the part of the heart that is affected. Narrowed coronary arteries are treated with cholesterol and blood pressure medication. When needed, an affiliated hospital adds angioplasty and coronary stenting. Electrical problems are treated with rate control medication, ablation, or a pacemaker. That device is checked by pacemaker interrogation. Valve disease is monitored with serial echocardiograms. It is referred for repair or replacement when it becomes severe. Weak pumping is treated with medications that protect and unload the heart muscle. Underlying all of it is prevention. That work is guided by heart healthy living plus advanced lipid testing. Cardiac rehabilitation helps after an event. What to expect at your visit Bring your medication list, recent labs and any prior heart test reports. Your appointment includes a history and an exam. Dr. Nanavati places the stethoscope on several spots to hear each valve. The visit also includes blood pressure and an ECG. If an echocardiogram is ordered, expect to lie on your side. A technologist takes images for about half an hour. Dr. Nanavati will show you what the pictures mean using your own anatomy. You can review other patient education videos or read the FAQs page beforehand. When to see a cardiologist See a cardiologist if you have a murmur, an abnormal ECG, exertional breathlessness or palpitations. A family history of early heart disease is another reason. Screening also makes sense if you have high blood pressure, high cholesterol or diabetes. Request an appointment online or call the Bonita office at (619) 585-0476.

Other Related Diseases ## Heart Murmur URL: https://www.heartcare4life.com/conditions/heart-murmur Summary: Heart murmur evaluation with in-office echocardiography from Dr. Vimal Nanavati, MD, FACC at HeartCare4life in Bonita, San Diego and Redding, California. What is a heart murmur? A heart murmur is an extra swishing or whooshing sound a doctor hears through a stethoscope. Turbulent blood flow in or near the heart makes that sound. A murmur is a sound, not a disease. Normal blood flow is smooth and quiet. Blood becomes turbulent and audible when it speeds up, squeezes through a narrowed valve, or leaks backward through one that does not close. Murmurs are sorted into two groups. Innocent murmurs occur in structurally normal hearts. They are common in children, in pregnancy, with fever, and with anemia or an overactive thyroid. Abnormal murmurs signal a real problem. Most often a valve has stiffened or started to leak. Doctors grade a murmur by loudness and describe when it occurs in the heartbeat. The stethoscope alone cannot settle the question. An ultrasound of the heart is what distinguishes a harmless murmur from valve disease, as the American Heart Association explains. Symptoms to watch for Most murmurs cause no symptoms and are found during a routine exam. Symptoms usually mean the underlying valve problem has progressed. Call the office if you have a known murmur along with: - Shortness of breath with activity, or when lying flat. - Swelling in the ankles, feet or abdomen. - Fatigue or reduced stamina that is new for you. - Palpitations or a persistently irregular pulse. - Lightheadedness with exertion - Unexplained fevers, which can signal an infection of a valve. Call 911 if you have: - Fainting, especially during exercise - Chest pain or pressure lasting more than a few minutes. - Severe shortness of breath at rest, or waking gasping for air. - Coughing up pink, frothy sputum. Fainting during exertion with a known murmur can indicate severe narrowing of the aortic valve. It requires emergency care. The MedlinePlus overview of valve disease describes how these symptoms develop. How Dr. Nanavati diagnoses it The exam is the starting point, and ultrasound gives the answer. Dr. Nanavati listens over each valve area. He listens standing and sitting, and uses maneuvers that change how loud a murmur sounds. - Transthoracic echocardiography is the definitive test. It shows each valve moving in real time. It measures how much blood leaks or how tight a narrowing is, and it reports the pumping strength. - Echocardiogram studies are performed in the office. They take about 30 minutes and use no radiation. - Transesophageal echocardiography gives a much closer view. It is used when the standard study is inconclusive or when infection of a valve is suspected. - Electrocardiogram (ECG or EKG) checks for chamber enlargement and rhythm problems caused by a leaking or narrowed valve. - Treadmill stress testing measures your true exercise capacity. It helps when symptoms and valve measurements do not match. - Holter monitoring is added if you also have palpitations or suspected atrial fibrillation, which valve disease can cause. Treatment options Many murmurs need nothing more than reassurance and a repeat listen. When a valve problem is confirmed, treatment follows its severity. Watchful waiting. Mild to moderate valve disease is monitored with echocardiograms at set intervals, often yearly. The purpose is to catch the moment the valve becomes severe. That has to happen before the heart muscle is damaged. Keeping that schedule is the treatment. Risk factor management. Blood pressure control reduces the load on a leaking valve. Cholesterol treatment guided by advanced lipid testing protects the heart muscle overall. So do the habits in Life's Essential 8. Good dental hygiene lowers the risk of a valve infection. Medication. Diuretics relieve fluid buildup. Blood pressure medicines reduce strain. Rate control or anticoagulation is added if AFib develops. Medication does not fix a valve. It does manage symptoms and protect the heart. Repair or replacement. Severe valve disease is treated with surgical repair, surgical replacement, or a catheter based valve procedure. These happen at an affiliated hospital. Dr. Nanavati handles the evaluation, timing and referral, then follows you afterward. Cardiac rehabilitation supports recovery. What to expect at your visit Bring the note or report that mentioned the murmur. Also bring your medication list and any previous echocardiogram results for comparison. Your appointment includes a full cardiac exam, blood pressure and an electrocardiogram. If an echocardiogram is ordered, you lie on your left side. A technologist moves a probe over your chest with gel. It is painless and involves no needles. Dr. Nanavati reviews the images with you. He tells you plainly whether the murmur is innocent. If it is not, he tells you which valve is involved and when the next study is due. The FAQs page covers what to bring. When to see a cardiologist Get evaluated if a clinician mentions a murmur you have never had checked. Get evaluated if a known murmur sounds louder. The same goes for a murmur that comes with breathlessness, swelling or fainting. Children with murmurs should be assessed, as should adults with a bicuspid aortic valve or a family history of valve disease. So should anyone with an aortic aneurysm.

Other Related Diseases ## Heart Palpitations URL: https://www.heartcare4life.com/conditions/heart-palpitations Summary: Find out what is causing your palpitations with in-office ECG and wearable rhythm monitoring from Dr. Vimal Nanavati, MD, FACC in San Diego and Redding, CA. What are heart palpitations? Heart palpitations are the sensation of feeling your own heartbeat. People describe fluttering, pounding, racing, thumping, or a skip followed by a heavy thud. You may feel it in the chest, the throat or the neck. Palpitations are a symptom, not a diagnosis. They are also extremely common. Many come from ordinary triggers: caffeine, alcohol, nicotine, stress, poor sleep, dehydration, exercise, fever, hormonal changes and some cold or asthma medications. Others come from premature beats. These are early extra beats that make the following beat feel forceful. A smaller group comes from a true arrhythmia. That may be atrial fibrillation or a fast rhythm from the lower chambers. Thyroid problems, anemia and low blood counts also cause palpitations. Most palpitations are harmless. Still, the National Heart, Lung, and Blood Institute advises evaluation when they are frequent, prolonged, or paired with other symptoms. Symptoms to watch for The company palpitations keep is what matters most. Isolated flutters in an otherwise healthy person are usually benign. Call the office to be seen if you have: - Palpitations that happen most days, or last more than a few minutes. - A pulse that feels irregular when you check it at your wrist. - Palpitations with mild lightheadedness or breathlessness. - Episodes that start and stop abruptly, like a switch. - Palpitations that began after a new medication or supplement. Call 911 if palpitations come with: - Chest pain or pressure - Fainting, or nearly passing out. - Severe shortness of breath at rest. - Confusion, or sudden weakness on one side of the body. Fainting with palpitations is never something to watch and wait on. The American Heart Association treats it as a warning sign of a serious rhythm problem. How Dr. Nanavati diagnoses it The whole task is capturing your heart on a recording while you feel the symptom. Dr. Nanavati matches the monitor to how often your episodes happen. - Electrocardiogram (ECG or EKG) is done in the office. It documents the rhythm at that moment. - Holter monitoring records continuously for 24 to 48 hours. It is ideal when symptoms come daily. - 7 to 10 day ambulatory rhythm monitoring is used when episodes occur a few times a week. - Loop recorder implantation and interrogation places a small monitor under the skin for rare episodes or unexplained fainting. It can record for years. - Echocardiogram rules out a structural cause such as a valve problem or weak pumping. - Treadmill stress testing is used when palpitations appear specifically with exercise. - Advanced lipid testing and routine blood work check thyroid function, electrolytes, blood count and cholesterol. - Pacemaker interrogation or defibrillator interrogation retrieves stored recordings if you already have a device. Monitors are fitted in the office. Readings from your smart watch are reviewed alongside them. Treatment options Most patients are treated by removing a trigger rather than by taking a new drug. Treatment follows the recording. Lifestyle first. Cut back caffeine and alcohol. Stop nicotine, improve sleep, stay hydrated and address stress. Check labels on decongestants, energy drinks, diet aids and pre workout supplements. Stimulants are a frequent hidden cause. Treating sleep apnea reduces palpitations for many people. So does controlling blood pressure. The Life's Essential 8 habits give a practical framework. Correct the underlying cause. An overactive thyroid, anemia, dehydration, fever or a medication side effect all have specific fixes. Reassurance itself is treatment when the monitor shows a normal rhythm. Knowing the beats are harmless makes them far less distressing. Medication. A low dose beta blocker often settles premature beats that are frequent and bothersome. If the recording shows atrial fibrillation, rate control and stroke prevention become the priority. Some patients cannot take blood thinners. For them, left atrial appendage closure is considered. Procedures. Catheter ablation can cure certain fast rhythms. It is done at an affiliated hospital. Cardiac rehabilitation helps patients regain confidence with exercise after an event. What to expect at your visit Keep a short symptom diary before you come. Note the time, the duration, what you were doing and what you had eaten or drunk. Bring your medication list including supplements, and any smart watch tracings. The visit includes an exam, blood pressure, pulse check and an ECG. If a monitor is ordered, staff apply it before you leave. They also show you how to log symptoms. When the report comes back you get a direct answer about what your heart was doing during each episode. The FAQs page explains what to bring. When to see a cardiologist Get evaluated for palpitations that are frequent or worsening. Do the same for palpitations with chest pain, breathlessness or fainting. Evaluation is also warranted if you have known heart disease or a heart murmur. A family history of sudden cardiac death at a young age is another reason.

Other Related Diseases ## Ventricular Arrhythmias URL: https://www.heartcare4life.com/conditions/ventricular-arrhythmias Summary: PVCs and ventricular arrhythmia evaluation with in-office ECG, monitoring and stress testing from Dr. Vimal Nanavati, MD, FACC in San Diego and Redding, CA. What are ventricular arrhythmias? Ventricular arrhythmias are abnormal heart rhythms that start in the ventricles. The ventricles are the two lower pumping chambers. Normally the electrical signal begins in the upper chambers and travels down. Sometimes it fires from the ventricles instead. The beat then arrives early, or the rhythm runs away at high speed. There are three main types. Premature ventricular contractions, or PVCs, are single early beats that feel like a skip or a thump. They are common even in healthy hearts. Ventricular tachycardia is a run of fast beats from the ventricles that can drop blood pressure. Ventricular fibrillation is chaotic electrical activity in which the heart cannot pump at all. It causes cardiac arrest within seconds. Risk depends heavily on the underlying heart. Occasional PVCs in a structurally normal heart are usually benign. The same beats in a weakened heart matter far more, as the National Heart, Lung, and Blood Institute explains. Symptoms to watch for Many ventricular arrhythmias are felt as a skipped beat followed by a forceful one. Others cause no sensation and appear only on a tracing. Call the office if you have: - Frequent skipped beats, thumps or a flip flop feeling in the chest. - Palpitations that increase with rest, caffeine or stress. - New shortness of breath or reduced exercise tolerance. - Mild lightheadedness with an episode. - Known heart disease and any new palpitations. Call 911 for any of these: - Fainting, or nearly fainting, with a racing heartbeat. - Chest pain or pressure with palpitations. - A sustained racing heartbeat that will not slow down. - Severe shortness of breath, confusion or gray, clammy skin. If someone collapses and is unresponsive without normal breathing, call 911. Begin CPR and use an AED if one is nearby. The American Heart Association notes that immediate bystander CPR can double or triple the chance of survival. How Dr. Nanavati diagnoses it Two questions guide the workup. What is the rhythm? Is the heart muscle underneath it normal? Both must be answered. - Electrocardiogram (ECG or EKG) identifies the shape of the extra beats. It also screens for prior heart muscle injury. - Holter monitoring counts how many PVCs occur in 24 to 48 hours. The burden, as a percentage of total beats, guides treatment. - 7 to 10 day ambulatory rhythm monitoring captures episodes that are less frequent. - Loop recorder implantation and interrogation is used for unexplained fainting or very rare events. - Echocardiogram measures the ejection fraction. It also looks for scar, weakness or a thickened muscle. - Treadmill stress testing shows whether the beats increase or suppress with exercise. That is an important clue. - Nuclear stress testing and advanced stress testing look for reduced blood flow as the trigger. - Ischemic heart disease evaluation is used when coronary artery disease is the suspected cause. - Defibrillator interrogation downloads stored episodes if you already have a device. Blood work rounds out the evaluation. It covers electrolytes, magnesium, thyroid function and advanced lipid testing. Treatment options Treatment depends on the burden of extra beats. It also depends on your symptoms and the strength of your heart muscle. Correct the triggers. Low potassium or magnesium can provoke ventricular beats. So can caffeine, alcohol, nicotine, stimulants and decongestants. Poor sleep and untreated sleep apnea do the same. Correcting them often reduces the burden substantially. The heart healthy living steps from NHLBI support the rest. Observation. Infrequent PVCs with a normal echocardiogram usually need no drug at all. Periodic monitoring confirms the burden stays low. Medication. Beta blockers are the usual first choice for symptomatic PVCs. Antiarrhythmic drugs are reserved for higher burden or sustained rhythms. Treating the underlying disease matters as much as the antiarrhythmic itself. That disease may be coronary artery disease, high blood pressure or a weak heart muscle. This approach keeps with American College of Cardiology guidelines. Procedures. Catheter ablation can eliminate the focus producing frequent PVCs or ventricular tachycardia. An implantable defibrillator is recommended when the risk of sudden cardiac arrest is high. That is typically the case with a significantly weakened pumping function. Both are done at affiliated hospitals, with cardiac rehabilitation afterward to rebuild exercise capacity safely. What to expect at your visit Bring your medication list, recent blood work and any prior ECGs or monitor reports. Those older records allow direct comparison. Describe when the beats occur. Say whether rest or exercise makes them worse, and whether you have ever fainted. The visit includes an exam, blood pressure and an ECG. Monitors are fitted in the office and echocardiography is performed on site. You leave knowing your PVC burden if it has been measured. You also learn whether your heart muscle is normal and what your risk actually is. Vague reassurance is not the goal. The FAQs page covers preparation. When to see a cardiologist See a cardiologist for frequent skipped beats or fainting of unknown cause. Come in for palpitations with any chest pain or breathlessness. Also come in for PVCs found on an ECG when you have known heart disease. A family history of sudden death before age 50 warrants prompt evaluation.

Other Related Diseases ## Ventricular Tachycardia URL: https://www.heartcare4life.com/conditions/ventricular-tachycardia Summary: Ventricular tachycardia evaluation and treatment, from rhythm monitoring to defibrillator care, with Dr. Vimal Nanavati, MD, FACC in San Diego and Redding. What is ventricular tachycardia? Ventricular tachycardia is a fast heart rhythm that starts in the ventricles. The ventricles are the heart's two lower pumping chambers. Doctors often shorten the name to VT. VT means three or more beats in a row from the ventricles at a rate above 100 beats per minute. The signal bypasses the heart's normal wiring. The chambers do not fill properly between beats, so less blood reaches the body with each contraction. Short runs lasting a few seconds are called non sustained VT and may cause only a flutter. Runs lasting longer than 30 seconds are called sustained VT. So is any run that drops your blood pressure. Sustained VT is a medical emergency. VT most often occurs in a heart scarred by a previous heart attack, weakened by cardiomyopathy, or affected by an inherited electrical disorder. Untreated sustained VT can deteriorate into ventricular fibrillation and cardiac arrest. That is why the American Heart Association classifies it among the most serious arrhythmias. Symptoms to watch for VT often announces itself abruptly. How it feels depends on two things. One is how fast it runs. The other is how strong your heart muscle is. Call the office if you have: - Brief flutters or a run of rapid beats that stops on its own. - Palpitations with mild dizziness that resolve quickly. - Reduced exercise tolerance or new fatigue. - Known heart disease and any new rhythm sensation. - Shocks or beeping from an implanted defibrillator, which need prompt review. Call 911 immediately for: - A sustained racing heartbeat that does not slow down. - Fainting or near fainting - Chest pain or pressure with a racing heart. - Severe shortness of breath, confusion or clammy, gray skin. - More than one defibrillator shock in 24 hours. If someone collapses and is not breathing normally, call 911. Start CPR and use an AED. Survival from cardiac arrest depends on how quickly CPR and defibrillation begin. How Dr. Nanavati diagnoses it VT must be documented on a tracing. The heart muscle underneath it must also be assessed. Both parts drive treatment. - Electrocardiogram (ECG or EKG) captures the rhythm. It also shows evidence of a prior heart attack that could be the source. - Holter monitoring records every beat for 24 to 48 hours. It finds non sustained runs. - 7 to 10 day ambulatory rhythm monitoring extends the search for episodes that are less frequent. - Loop recorder implantation and interrogation monitors long term after unexplained fainting. - Echocardiogram measures the ejection fraction. That is the single most important number for judging risk. - Nuclear stress testing and advanced stress testing look for reduced blood flow that provokes the rhythm. - Ischemic heart disease evaluation assesses coronary artery disease as the underlying cause. - Defibrillator interrogation and pacemaker interrogation read stored episodes. They also check device settings. A transradial angiogram defines the coronary anatomy when a blockage is suspected. It is done at an affiliated hospital. Electrolyte, magnesium and thyroid testing complete the picture. So does advanced lipid testing. Treatment options Treatment has two aims. It stops episodes and prevents sudden cardiac arrest. Nearly every patient needs both addressed. Reverse the triggers. Low potassium and magnesium can provoke VT. So can stimulants, alcohol and certain decongestants. Some prescription drugs that prolong the QT interval do the same. Reviewing every medication and supplement is part of the first visit. Treat the underlying heart. Ischemia is sometimes the cause. Blood flow is restored with angioplasty and coronary stenting. That removes the trigger. Other medications strengthen and protect a weakened heart muscle. They reduce episodes over time, following American College of Cardiology guidelines. Medication. Beta blockers are the foundation. Antiarrhythmic drugs such as amiodarone or sotalol are added for recurrent episodes. Dr. Nanavati monitors them closely. Devices and ablation. An implantable cardioverter defibrillator monitors your rhythm continuously. It delivers a shock to stop a lethal rhythm. It is the standard protection for patients with a significantly weakened pumping function. Catheter ablation targets the scar tissue circuit driving VT. It can markedly reduce episodes and shocks. A temporary pacemaker may be used in urgent hospital settings. Cardiac rehabilitation follows, so you can return to activity under supervision. What to expect at your visit Bring your medication list, any hospital discharge paperwork and prior ECGs. Bring your device card too if you have a pacemaker or defibrillator. Describe every episode. Say how it started, how long it lasted, whether you fainted and what stopped it. The visit includes an exam, blood pressure and an ECG. Device interrogation and echocardiography are performed in the office. You will leave with a specific plan. It covers medication, monitoring, activity limits and exactly when to call 911. Family members are welcome, and CPR training is encouraged. The FAQs page answers common questions. When to see a cardiologist Seek prompt evaluation after any fainting episode or a documented run of VT. Do the same after a defibrillator shock. Also call for palpitations with chest pain or breathlessness. Get assessed if you have had a prior heart attack or have a weakened heart muscle. The same applies to a family history of sudden death before age 50. The ventricular arrhythmias page covers related rhythms. Request an appointment online or call the Bonita office at (619) 585-0476.

We recommend contacting our office prior to your visit so our staff can help verify insurance participation and benefits. What should I bring to my first appointment? To help ensure a thorough and efficient visit, please bring: - A list of all current medications (or the medications themselves) - Any recent medical records or test results - A list of known allergies - Insurance information and photo identification - A summary of recent hospitalizations or procedures, if applicable Medication Safety & Heart Health Why are medication errors dangerous? A medication error is any preventable mistake in prescribing, dispensing, or taking a drug. The U.S. Food and Drug Administration reviews reports of medication errors involving regulated drug products. Some errors cause no harm, but others lead to serious injury. Cardiovascular patients are especially vulnerable because heart medications are complex. Many require exact doses, careful timing, and regular monitoring. How do medication errors occur? Medication errors can happen at several points in your care: - At home, due to missed doses, incorrect timing, or confusion between medications - At the pharmacy, due to labeling or dispensing errors - In the hospital, during transitions of care or medication changes Clear communication between patients, physicians, and pharmacists is critical. How can I reduce my risk of medication errors? HeartCare4Life recommends: - Bringing all medications to every doctor visit (including supplements) - Keeping an updated medication list with dosages - Reviewing medication changes carefully after hospital discharge - Asking questions if instructions are unclear - Informing your physician of side effects or concerns promptly MedlinePlus offers further patient guidance on avoiding medication errors. Importance of Regular Doctor Visits Why are routine cardiology visits important? Regular doctor visits allow early detection of heart disease, monitoring of existing conditions, and timely adjustment of medications or treatment plans. Preventive care plays a critical role in reducing the risk of heart attack, stroke, and sudden cardiac events. Smoking & Heart Disease How dangerous is cigarette smoking for heart patients? Smoking damages the heart and blood vessels. Cigarette smoke carries more than 7,000 chemicals, and the FDA explains how smoking affects heart health. Smoking contributes to coronary heart disease, high blood pressure, and stroke. Public health agencies do not consider any level of smoking safe. For patients who already have heart disease, stopping is one of the most important steps available. MedlinePlus reviews the wider health effects of smoking. What makes cigarettes so hard to quit? Nicotine is the ingredient that keeps people using tobacco, as the FDA describes in why tobacco products are addictive. That addiction is why many patients keep smoking even after a cardiac event. Quitting lowers cardiovascular risk, and counseling or medication improves the odds. See MedlinePlus on quitting smoking for methods that work. Healthy Dining & Heart-Smart Choices How can I eat heart-healthy when dining out? HeartCare4Life encourages home-cooked meals whenever possible. The tips below follow heart-healthy eating guidance from the American Heart Association and the National Heart, Lung, and Blood Institute. When dining out: - Avoid appetizers and fried foods - Limit bread and butter - Choose fish such as salmon or halibut, prepared without butter - Select vegetables or baked potatoes instead of fries - Avoid heavy sauces, bacon, and creamy dressings - Choose vinaigrette on the side - Skip dessert or opt for fruit or sorbet - Avoid sugary beverages and added sugars Mindful choices at the table support long-term heart health. MedlinePlus has more on building a balanced diet. ## Feedback URL: https://www.heartcare4life.com/feedback Summary: We are trying to make our website as helpful and informative as possible, so we need your feedback.

Open Payments Database Notice We provide this notice so our patients know the federal Open Payments database exists and know how to use it. What Open Payments Is Open Payments is a national disclosure program run by the federal Centers for Medicare and Medicaid Services, or CMS. It was created by the Physician Payments Sunshine Act, passed by Congress in 2010. Reporting began in 2013. The law requires manufacturers of drugs, medical devices, and biologics to report any payment or transfer of value worth more than about ten dollars made to a physician or a teaching hospital. CMS publishes that data in a free, searchable public database. Congress did not prohibit these payments. It required that they be visible. Why You Might Want to Look Financial ties between industry and medicine are ordinary and often necessary. They are also worth knowing about. A patient advised to consider a particular stent, device, or medication may reasonably want to know whether the physician recommending it has a financial relationship with the company that makes it. Looking is not an accusation. The database exists so that you can check without having to ask. What Gets Reported - Consulting and speaking fees for advising, lecturing, or serving on a panel - Research payments, including funding for clinical trials - Food and beverage, often a modest meal at an educational program - Travel and lodging for a meeting or device training - Education, including textbooks and journal reprints - Royalties, licensing, grants, and gifts - Ownership or investment interest held by a physician or immediate family member What the Numbers Do and Do Not Mean An entry means one thing. A manufacturer reported a payment or transfer of value. It does not mean the payment was improper, or that the physician was paid to prescribe or implant anything. Much of the database is meals at conferences and travel to training on a new device. Physicians who teach, lecture, or run clinical trials show larger totals, because that work is compensated. The data has limits. Manufacturers submit it, and entries are sometimes attributed to the wrong physician, especially with common names. Treat what you find as a starting point for a conversation with your doctor, not as a verdict. Look Up Any Physician Search the federal database yourself, free and without an account: https://openpaymentsdata.cms.gov/ You can search by physician name, by city or state, or by manufacturer. Results cover all physicians and teaching hospitals nationwide. Ask Us If you have a question about anything you find, ask. Call the Bonita office at (619) 585-0476 or the Redding office at (530) 433-5427. ## Patient Info URL: https://www.heartcare4life.com/patient-info Summary: New patient forms, what to bring, bill payment, insurance verification and short videos explaining cardiac tests, so your visit is spent with the doctor. This section covers the practical side of being a patient here. It is the paperwork, the coverage questions, the billing, and the plain-language explanations of what a test actually involves. None of it is clinical advice. All of it is the sort of thing that makes a cardiology visit go smoothly instead of anxiously. Where to Start If you are a new patient with an appointment booked, start with the patient forms. Completing your history, medication list, and insurance details before you arrive means your appointment time is spent with the doctor rather than at a clipboard. Bring your insurance card, a photo ID, a current list of medications and doses, and any prior cardiac records, ECGs, or imaging reports you can get hold of. Records from a previous cardiologist are especially useful. If you are unsure whether we take your plan, go to the insurance page. It explains how to verify coverage, what to have ready when you call your insurer, the difference between a referral and a prior authorization, and why Medicare Advantage plans follow different rules than Original Medicare. It does not list payers, because plan networks change and the only reliable answer comes from calling us. If a test has been ordered and you do not know what it is, the education videos explain cardiac anatomy, common conditions, and the tests and procedures we perform. Watching a three-minute animation of an echocardiogram or a stress test is usually more reassuring than reading about it. If you have received a statement, the bill payment page sets out your options. If a charge does not make sense, call before you assume it is wrong. Hospital-based procedures generate several separate bills, which surprises people. Questions the Website Cannot Answer Anything specific to you needs a phone call or a visit. Call (619) 585-0476 for Bonita and South San Diego, or (530) 433-5427 for Redding. Office hours are Monday through Thursday, 9:00 am to 5:00 pm, and Friday, 9:00 am to 12:00 pm. If you are having chest pain, shortness of breath, or symptoms you think may be a heart attack, call 911. ## Bill Payment Options URL: https://www.heartcare4life.com/patient-info/bill-payment Summary: Bill Payment Options | HeartCare4life, Dr. Vimal Nanavati, Board Certified in Cardiology and Interventional Cardiology, Bonita, Redding, San Diego, CA Payments can be made in person at either office at the time of your visit. To make a payment, ask about your balance, or discuss a payment arrangement, please call the office that provided your care: - South San Diego (Bonita) and North San Diego: (619) 585-0476 - Northern California (Redding): (530) 433-5427 We accept most insurance plans; see Medical Insurance Information. Online bill payment will be added to this page when it becomes available. ## Medical Insurance Information URL: https://www.heartcare4life.com/patient-info/insurance Summary: How to verify your cardiology coverage before the visit: what to ask your insurer, referral versus prior authorization, and why network status can change. Cardiology involves office visits, diagnostic testing, and sometimes hospital-based procedures. The same plan can cover each of those differently. A little work before your visit prevents most billing surprises. Call our office to confirm we participate with your specific plan before you come in. Bonita and South San Diego: (619) 585-0476. Redding and Northern California: (530) 433-5427. Verify Coverage Before Your Appointment Do not rely on a plan name alone. Insurers sell many products under one brand, and networks differ between them. Two people with cards from the same company can have very different coverage. Call the member services number on the back of your card. Ask for a reference number for the call. Then call our office so we can verify from our side. What to Have Ready When You Call - Your member ID number and group number - The plan name exactly as printed, including any suffix such as HMO, PPO, EPO, or Advantage - The subscriber's name and date of birth, if the policy is not in your name - Our practice name and address, so they can check network status - The specific test or procedure name, and the symptom or diagnosis prompting it That last item matters. An insurer answers very differently about an office visit, an echocardiogram, and a cardiac catheterization. Ask about the exact service. In-Network Versus Out-of-Network In-network means the practice has a contract with your plan. Rates are pre-negotiated, and you generally pay your plan's normal copay, coinsurance, and deductible. Out-of-network means no such contract exists. Your plan may pay a smaller share, apply a higher separate deductible, or pay nothing. Some plans, particularly HMOs, cover out-of-network care only in an emergency. Network status can change from year to year. Confirm it each plan year. Referrals Versus Prior Authorizations These are two different things, and cardiology often involves both. A referral comes from your primary care physician and authorizes you to see a specialist. HMO and many Medicare Advantage plans require one before a cardiology consultation. PPO plans usually do not. Without a required referral, the visit may be denied outright. A prior authorization comes from your insurer and approves a specific test or procedure before it is performed. Advanced cardiac imaging, nuclear stress testing, CT angiography, and most catheterization-based procedures commonly require one. Routine office visits and basic ECGs usually do not. Prior authorization takes time. Allow several business days, longer if the insurer asks for additional records. Questions Worth Asking Your Insurer - Is this practice in network for my specific plan? - Do I need a referral from my primary care physician? - Does this test or procedure require prior authorization? - What is my remaining deductible for this plan year? - What is my copay or coinsurance for a specialist visit, and for diagnostic testing? - Is there a separate facility fee if the service is done at a hospital? Medicare and Medicare Advantage Are Not the Same Original Medicare, Parts A and B, generally does not require a referral to see a cardiologist. Part B typically covers medically necessary cardiac testing after your deductible, and you owe coinsurance unless a supplement plan covers it. Medicare Advantage, or Part C, is a private plan. It must cover what Medicare covers, but it sets its own network, referral rules, and prior authorization requirements. Those rules often look more like a commercial HMO. Treat an Advantage plan as a commercial plan when you call. What to Expect on Your Bill For a diagnostic test done in our office, such as an ECG, echocardiogram, or treadmill stress test, you will usually see one bill from the practice. It may list a technical component for performing the study and a professional component for interpreting it. For a hospital-based procedure, such as an angiogram, angioplasty, or stenting, expect more than one bill. The hospital bills a facility fee. The physician bills separately for professional services. Anesthesia and radiology may bill on their own. Each bill is processed against your benefits independently, so several statements for one procedure is normal, not an error. Coverage questions are easier to answer than to guess at. Call the office before your visit.

Privacy Policy and HIPAA Notice Effective Date: 7th July 2026 HeartCare4life, the cardiology practice of Dr. Vimal Nanavati (Advanced Heart Care, Inc.), respects your privacy. This policy explains two related things. First, how we handle your protected health information as a HIPAA covered entity. Second, how we handle the information you give us or generate when you use this website. By using our website, you acknowledge that you have read and understood this Privacy Policy. We Are a HIPAA Covered Entity HeartCare4life is a health care provider that transmits health information electronically in connection with covered transactions. That makes us a covered entity under the Health Insurance Portability and Accountability Act of 1996 and its implementing regulations, together known as HIPAA. HIPAA requires us to keep your protected health information private. It requires us to give you notice of our legal duties and privacy practices. It requires us to follow the terms of the notice currently in effect. We take those duties seriously. You can read the federal rules for yourself at hhs.gov/hipaa. What Protected Health Information Means Protected health information, often shortened to PHI, is individually identifiable health information that we create or receive. It covers your past, present, or future physical or mental health. It covers the care you receive from us. It covers payment for that care. In practice, PHI includes your name, address, date of birth, telephone number, and email address when they are tied to your care. It includes your medical record number, insurance and account numbers, appointment history, test results, images, diagnoses, medications, and clinical notes. Not everything on this website is PHI. Anonymous website analytics that cannot be linked to you as a patient are not PHI. Where the two overlap, we treat the information as PHI. Website Forms Are Not a Secure Patient Portal Please read this section before you send us anything. The contact forms, appointment request forms, feedback forms, and general email addresses on this website are convenience tools. They are not a secure, encrypted patient portal. Ordinary email is not secure either. Use these forms only to tell us who you are, how to reach you, and when you would like to be seen. Do not include detailed medical history. Do not include test results, imaging reports, medication lists, symptom narratives, or anything else you would consider sensitive. If you need to send clinical information, call the office and we will tell you a secure way to do it. If your situation is urgent, call the office. If it is an emergency, call 911. Once your information reaches us and becomes part of your record, it is protected as PHI under HIPAA. The risk sits in the transmission, not in our handling afterward. How We Use and Disclose Health Information We use and disclose your health information for treatment, for payment, and for our health care operations. HIPAA permits these uses without your separate written authorization. Treatment means using your information to provide, coordinate, and manage your care. This includes sharing information with other physicians, hospitals, laboratories, imaging centers, and pharmacies involved in your care. Payment means using your information to bill and collect for the care we provide. This includes verifying coverage, obtaining prior authorization, and submitting claims to your health plan. Health care operations means the business activities that keep the practice running. This includes quality review, staff training, credentialing, audits, and administration. We may also use or disclose your information where the law requires or permits it. Examples include public health reporting, court orders, and reporting suspected abuse or neglect. For most other uses, including marketing and any sale of your information, we will ask for your written authorization first. You may revoke that authorization in writing at any time. Your HIPAA Rights HIPAA gives you specific rights over your health information. You have the right to: - Access and inspect your record. You may ask to see and get a copy of the health information we hold about you. We may charge a reasonable, cost-based fee for copies. - Request an amendment. If you believe information in your record is incorrect or incomplete, you may ask us to amend it. We may deny the request in limited circumstances, and we will explain the reason in writing if we do. - Receive an accounting of disclosures. You may ask for a list of certain disclosures we have made of your health information. Disclosures for treatment, payment, and health care operations are generally excluded from this list. - Request restrictions. You may ask us to limit how we use or disclose your information. We are not required to agree to every request. We must agree when you pay for a service in full out of pocket and ask us not to share that information with your health plan. - Request confidential communications. You may ask us to contact you at a particular address or phone number. - Receive a paper copy of the Notice of Privacy Practices. You have this right even if you agreed to receive the notice electronically. - Be notified of a breach. We will notify you if a breach compromises the privacy or security of your health information. To exercise any of these rights, contact the office. We may ask you to put the request in writing and to verify your identity before we act on it.

Learn how the patch works, how to wear it, and what results mean. What is a 7-10 Day Ambulatory Rhythm Monitor? A 7 to 10 day ambulatory rhythm monitor is a small wearable device. It records every heartbeat for a week or more while you go about your normal life. It is usually a single adhesive patch worn on the left side of the chest. Some versions are a compact recorder connected to two or three sticky electrodes. The monitor follows your heart's electrical signals without interruption. Brief rhythm changes are common, and a short in-office test would miss them. This longer test still captures them. You press a button whenever you feel a symptom. Your cardiologist can then line up what you felt with what your heart was doing. The device is painless, worn under clothing, and does not limit most daily activity. At the end of the recording period, the data becomes a report showing your heart rate range, any abnormal rhythms, and how often they occurred. Dr. Vimal Nanavati then reviews that report with you. Why Dr. Nanavati may recommend this An abnormal heart rhythm is called an arrhythmia. It simply means the heart is beating too fast, too slowly, or unevenly. The cause is a problem in the heart's electrical system. The American Heart Association explains arrhythmias as a broad group of conditions. Some are harmless extra beats, and others are rhythms that need prompt treatment. The catch is that many arrhythmias come and go. A standard electrocardiogram records only about ten seconds of heart activity. A Holter monitor covers one or two days. Symptoms that happen weekly rather than daily can easily slip past those shorter tests. Dr. Nanavati may recommend a 7 to 10 day monitor if you have: - Heart palpitations, fluttering, or a racing sensation that comes in episodes. - Dizziness, lightheadedness, or fainting with no clear cause. - Suspected atrial fibrillation, including after a stroke of unknown origin. - Unexplained shortness of breath or episodes of chest discomfort. - A need to check whether a rhythm medication is working. - A known arrhythmia that needs a longer look before treatment decisions are made. How to prepare Preparation is simple. Nothing about your usual routine has to change. - Shower or bathe before your appointment. Clean, dry skin helps the adhesive hold for the full week. - Skip lotions, oils, powders, and body sprays on your chest that morning. - Wear a loose top that buttons or zips in front. That makes placement easier. - Men with chest hair may need a small area shaved. Shaving helps the electrodes make good contact. - Keep taking all of your medications unless Dr. Nanavati specifically tells you otherwise. Bring your current list. - Tell the staff if you have ever had a skin reaction to bandages or adhesive tape. - Allow about 20 to 30 minutes for the visit where the monitor is applied. - Plan how you will keep a simple symptom diary, either on paper or on your phone. What happens during the procedure There is no procedure in the surgical sense. Placement is quick, painless, and done in the office. A member of the clinical team cleans and lightly buffs a small area of skin on your chest. This removes surface oil so the recording is clear. The patch or the electrodes are then pressed into place. If a recorder is used, it clips to your waistband or hangs on a lanyard. You are shown how to press the symptom button and how to note the time and what you were doing. That diary is genuinely useful, so do not skip it. Then you go home and live normally. Walk, work, cook, and sleep as usual. Most modern patches tolerate showering, though you should follow the specific instructions you are given. Avoid soaking in a bath, hot tub, or pool unless you are told the device allows it. If an electrode loosens, press it back down rather than pulling it off. Call the office if it will not stay put. Recovery and results There is nothing to recover from. When the recording period ends, you return the device to the office or mail it back in the prepaid packaging you were given. The recorded data is processed and summarized into a report. This usually takes several days to a couple of weeks, depending on the device and the volume of data. Dr. Nanavati reviews the full report along with your symptom diary. He then discusses the findings with you at a follow-up visit or by phone. Results fall into a few broad groups. The recording may be normal, which is reassuring and helps rule out a dangerous rhythm as the cause of your symptoms. It may show benign extra beats that need no treatment. The National Heart, Lung, and Blood Institute notes that many arrhythmias are harmless and need only monitoring. Or it may show a rhythm such as atrial fibrillation, or a fast rhythm from the lower chambers. Findings like these may lead to medication, blood thinning, or further imaging such as an echocardiogram. They may also lead to a referral for a rhythm procedure. Risks and safety This is one of the safest tests in cardiology. The monitor only listens. It does not send any energy into your body, and it uses no radiation, no dye, and no needles. The most common problem is skin irritation under the adhesive. Some people get redness, itching, or a mild rash. That usually fades within a few days after the patch comes off. Tell the office if the irritation is painful or spreading. Less commonly, an electrode falls off or the device stops recording. Either problem can mean repeating the study. Rarely, a week of monitoring still does not capture the symptom, especially if episodes are months apart. In that case a longer-term option such as an implanted loop recorder may be considered. The monitor does not alert anyone in real time. Call 911 if you have severe chest pain, fainting, or trouble breathing while wearing it. Do not wait for the report.

Preparation and results. What is Advanced Lipid Testing? Advanced lipid testing is a blood test that looks deeper than a standard cholesterol panel. A routine panel reports total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides. Advanced testing adds more measures, such as apolipoprotein B, usually written ApoB. It counts the cholesterol-carrying particles that can lodge in an artery wall. The panel may also include lipoprotein(a), written Lp(a), which is an inherited risk marker. It can add LDL particle number and particle size. Another measure is apolipoprotein A1, or ApoA1, which reflects protective cholesterol. These extra numbers matter. Some people have a normal LDL cholesterol level and still carry a high number of harmful particles. Others reach their LDL goal on medication. They can still remain at higher risk than the standard panel suggests. The test itself is an ordinary blood draw from a vein in the arm. It takes only a few minutes. Dr. Vimal Nanavati uses the results to sharpen your risk estimate and guide treatment. Why Dr. Nanavati may recommend this Cholesterol is carried through the blood inside particles. The damage to an artery is not only about how much cholesterol is present. It also depends on how many particles are knocking against the artery wall. That is the gap advanced testing is designed to close. Dr. Nanavati may suggest advanced lipid testing if you have: - A family history of early heart attack or stroke, especially in a parent or sibling before age 55 for men and 65 for women. - A normal or borderline LDL cholesterol but other risk factors such as diabetes, high blood pressure, or a history of smoking. - Known coronary artery disease or plaque found on a coronary CT angiogram or carotid ultrasound. - High triglycerides, low HDL, obesity, or metabolic syndrome. - LDL cholesterol at goal on a statin, but ongoing concern about residual risk. - A risk estimate that sits in a gray zone where the decision to start medication is not obvious. The American Heart Association explains how cholesterol contributes to plaque. The National Heart, Lung, and Blood Institute reviews blood cholesterol testing and treatment goals in plain language. How to prepare - Ask the office whether you need to fast. Some advanced panels can be drawn without fasting. If fasting is requested, it is usually 9 to 12 hours of water only. - Keep taking your medications, including statins and other cholesterol drugs, unless you are told otherwise. Stopping a statin before the draw gives a misleading picture. - Bring a full list of medications and supplements, including fish oil, niacin, and red yeast rice. - Avoid alcohol for 24 hours before the draw. Alcohol can raise triglycerides sharply. - Postpone the test if you have an active infection or have recently had surgery. The same applies after a heart attack in the last several weeks. Illness temporarily distorts lipid results. - Drink water beforehand. Being well hydrated makes the blood draw easier. - Allow about 15 to 20 minutes for the visit. What happens during the procedure There is no procedure to undergo. Advanced lipid testing is a standard venous blood draw. You sit in a chair and rest your arm on a support. A soft band goes around your upper arm, and the skin is cleaned. A thin needle then goes into a vein at the inside of the elbow. One or more tubes are filled. The needle comes out. Someone holds pressure for a minute, and a small bandage goes on. The whole draw takes about two to five minutes. Most people feel a brief pinch and nothing more. Have you fainted during blood draws in the past? Say so in advance, and you can lie down instead of sitting. You can eat, drive, work, and exercise immediately afterward. If you fasted, bring a snack for the trip home. Recovery and results There is nothing to recover from. A small bruise may appear at the puncture site and fade within a few days. Advanced lipid panels are processed at a specialized laboratory. Results typically take several days to about a week, longer than a basic cholesterol panel. Dr. Nanavati reviews the numbers in the context of your blood pressure, blood sugar, weight, family history, and any imaging you have had. What happens next depends on the pattern. A high ApoB or LDL particle number often leads to more intensive cholesterol lowering, even when LDL cholesterol looks acceptable. An elevated Lp(a) is largely genetic, and it does not respond much to diet or to statins. So it is used mainly to justify treating every other risk factor more aggressively, and to prompt screening of close relatives. Favorable numbers may support staying the course with lifestyle measures and periodic rechecks. Repeat testing is common about 6 to 12 weeks after a treatment change, then at longer intervals once you are stable. Risks and safety A blood draw is very low risk. The realistic downsides are a brief sting, a small bruise, and occasionally lightheadedness. Rarely, a vein is difficult to access and a second attempt is needed. Infection at the site is very uncommon. There is no radiation, no contrast dye, and no recovery period. The more meaningful caution is about interpretation. Lipid numbers move with illness, pregnancy, thyroid disease, alcohol intake, and recent weight change. So a single abnormal result is not a diagnosis. Advanced testing also does not replace a good risk conversation. It refines an estimate. Numbers are one input alongside your symptoms, examination, and family history. That is why you should review the results with your cardiologist rather than read them in isolation. You can do that at any of our three office locations.

How to prepare, what to expect, and results. What is Advanced Stress Testing? Advanced stress testing is a noninvasive imaging test. It shows how well blood reaches your heart muscle, first at rest and then under stress. The test uses positron emission tomography combined with computed tomography. That combination is usually shortened to PET/CT. You receive a small amount of a radioactive tracer through a vein. The scanner then maps where that tracer travels in the heart muscle. Most patients who need this test cannot exercise hard enough. So the stress phase uses a medication rather than a treadmill. That medication widens the coronary arteries and increases blood flow. Some areas may receive less blood during stress than at rest. Those areas suggest a narrowed artery. Cardiac PET produces sharper images than older nuclear scans. It also works better in people who are overweight, and it often uses a lower radiation dose. The whole visit usually takes about one to two hours. You go home the same day. Why Dr. Nanavati may recommend this Advanced stress testing answers a specific question. Is any part of your heart muscle being shortchanged on blood flow? That matters for chest pain and for shortness of breath. It also guides the decision about whether a blockage needs treatment. Dr. Nanavati may recommend it if you have: - Chest pain, pressure, or jaw and arm discomfort that could be cardiac. - Unexplained shortness of breath or a sharp drop in exercise tolerance. - Known or suspected coronary artery disease that needs to be graded before deciding on treatment. - An abnormal or inconclusive treadmill stress test or electrocardiogram. - Difficulty walking on a treadmill because of joint disease, lung disease, or general deconditioning. - A body habitus or breast tissue that degraded the images on a previous nuclear scan. - A need for cardiac clearance before major noncardiac surgery. The American Heart Association describes coronary artery disease and its warning signs. It is also worth reading the National Heart, Lung, and Blood Institute overview of heart tests. How to prepare Preparation for this test is stricter than for most. Skipping a step can invalidate the result. - Avoid all caffeine for at least 12 to 24 hours before the test. That means coffee, tea, soda, energy drinks, chocolate, and decaf, which still contains a little caffeine. Caffeine blocks the stress medication and can make the scan useless. - Do not eat for about four to six hours beforehand. Plain water is usually allowed. - Ask specifically about theophylline, aminophylline, and dipyridamole. These often need to be stopped days in advance. - Ask whether to hold beta blockers, nitrates, or diabetes medications on the morning of the test. Bring your medications with you so you can take them after. - Wear a comfortable two piece outfit and leave jewelry at home. You will need to be bare from the waist up under a gown. - Tell the office if you have asthma or emphysema, are pregnant or breastfeeding, or have had a reaction to a stress agent before. - Allow up to two hours. Arrange a ride if you are told you may receive sedation. What happens during the procedure You lie flat on a padded table. The table slides into the open ring of the scanner. It is not a closed tunnel, and you can see out. Electrodes go on your chest so the team can watch your heart rhythm continuously. A blood pressure cuff goes on your arm. A small intravenous line is started in a vein, usually in the arm. The rest images come first. A tracer goes in through the line. The scanner then records images for a few minutes while you lie still and breathe normally. You feel nothing from the tracer itself. Next comes the stress phase. The stress medication goes in through the same line over a short period. Many people feel warm, flushed, or briefly short of breath. Some notice a headache or a fluttering in the chest. This is expected, and it usually passes within a minute or two after the infusion ends. Tell the staff what you feel. A reversing medication can be given if the sensation is unpleasant. A second dose of tracer is given at peak stress. The scanner then records the stress images. The intravenous line comes out, and the team watches you briefly before you leave. Recovery and results Most people feel back to normal within minutes of the stress phase ending. You can eat and drink right away. Unless you were sedated, you can usually drive yourself home and return to work the same day. Drinking extra water for the rest of the day helps clear the tracer. The tracer leaves your body naturally within hours. A physician trained in cardiac imaging reads the images. The report typically reaches Dr. Nanavati within a few days. He then discusses the findings with you at a follow-up visit or by phone. A normal scan is strong reassurance that no major artery is significantly narrowed, and often means the next step is prevention rather than procedures. A mildly abnormal scan may be managed with medication, cholesterol control, and lifestyle change, sometimes supported by advanced lipid testing. A clearly abnormal scan may involve a large area of heart muscle. That can lead to a coronary angiogram and, if needed, angioplasty or coronary stenting. Risks and safety Cardiac PET/CT stress testing is considered safe, and it is done thousands of times a day in the United States. Still, it is not risk free. The stress medication commonly causes brief flushing, headache, chest tightness, shortness of breath, or nausea. These effects fade quickly. Vasodilator medications can trigger wheezing in people with asthma or significant emphysema. That is why your lung history matters. Serious reactions such as a heart attack or a dangerous rhythm are rare. The test also runs with continuous monitoring and emergency equipment on hand. The test involves ionizing radiation. The dose from cardiac PET is generally lower than from older nuclear stress tests. We use it because the information gained outweighs the small theoretical long term risk. Tell your care team if you are or might be pregnant, since the test is usually deferred in pregnancy. Call 911 if you develop severe chest pain or fainting after you get home. Do not wait for the report.

Learn why it is done, how to prepare, and what recovery looks like. What is Angioplasty? Angioplasty is a catheter-based procedure that reopens a heart artery narrowed by plaque. Plaque is the mix of cholesterol, calcium, and fibrous tissue that builds up inside artery walls. Doctors also call the procedure percutaneous coronary intervention, or PCI. There is no chest incision. A cardiologist numbs a spot at the wrist or the groin, then passes a thin flexible tube called a catheter into the artery. Live X-ray pictures guide it to the heart. Next the cardiologist steers a soft wire across the blockage. A tiny balloon travels over that wire and inflates for a few seconds. The balloon presses the plaque outward and stretches the artery open, so blood can flow freely again. In most cases the team then places a small metal mesh tube called a stent to hold the artery open. Angioplasty takes place in a hospital catheterization laboratory, not in the office. Many patients go home the same day. Why Dr. Nanavati may recommend this The goal of angioplasty is to restore blood flow to heart muscle that is not getting enough. That relieves symptoms, and during a heart attack it also saves muscle. Dr. Nanavati is board certified in interventional cardiology. He may recommend angioplasty if you have: - An active heart attack, where opening the artery quickly is the priority. The American Heart Association explains the warning signs of a heart attack. Calling 911 is always the right first step. - Chest pain or pressure with exertion that has not settled with medication. - A severe narrowing found on a coronary CT angiogram or a coronary angiogram. - A large area of poor blood flow on advanced stress testing. - Shortness of breath or reduced stamina traced to coronary artery disease. Angioplasty is not right for every blockage. Some patients do better with medication alone, and others are better served by bypass surgery. That decision depends on how many arteries are involved, where the narrowings sit, and your overall health. How to prepare - Expect blood tests, an electrocardiogram, and often an echocardiogram beforehand. In an emergency these steps are compressed or skipped. - Do not eat or drink after midnight, or as instructed. Small sips of water with essential pills are usually allowed. - Ask specifically about blood thinners, diabetes medications, and metformin, which is often held around contrast dye. Do not stop anything on your own. - Report any allergy to contrast dye, shellfish, latex, or medications, and tell the team about kidney disease. - Arrange for an adult to drive you home and, ideally, stay with you the first night. - Pack an overnight bag in case you stay, along with your medication list and insurance card. - Leave jewelry and valuables at home, and wear something easy to change out of. - Plan to be at the hospital for most of the day, even for a same-day discharge. What happens during the procedure You lie on a narrow padded table under a movable X-ray camera. Sticky electrodes monitor your heart, a cuff checks blood pressure, and a clip on your finger tracks oxygen. An intravenous line delivers fluids and medication. You are awake but relaxed. Most patients receive a mild sedative, so the experience often feels hazy afterward. The team cleans the wrist or groin and covers it with sterile drapes, and local anesthetic numbs the skin. You may feel pressure at that spot, but not sharp pain. The cardiologist threads the catheter through the artery to the heart. You will not feel it moving, because arteries have no sensory nerves inside. He injects contrast dye so the arteries show up on screen, and you may feel a brief warm flush. The balloon is then inflated at the blockage, usually for several seconds at a time. Some people feel chest pressure during inflation, which passes as the balloon deflates. Tell the team what you feel. A stent is usually placed and expanded into the artery wall, where it stays permanently. At the end, the catheter comes out, and a device or firm pressure closes the access site. Recovery and results If the wrist was used, a band applies pressure for a few hours. You can usually sit up right away. If the groin was used, you lie flat for several hours to prevent bleeding. Many stable patients go home the same day. After a heart attack, expect a hospital stay of several days. The result is known immediately. Your cardiologist can see the artery open on the screen before the procedure ends. He will explain what was found and what was done. At home, keep the access site clean and dry. Avoid heavy lifting, straining, and strenuous exercise for about a week. Most people return to desk work within a few days. Chest pain related to the blockage often improves quickly. The most important part of recovery is medication. If you received a stent, you will take aspirin plus a second antiplatelet drug. Together they keep the stent from clotting. Do not stop these without talking to your cardiologist. Cardiac rehabilitation is strongly encouraged, and MedlinePlus describes how cardiac rehabilitation improves long term outcomes. Risks and safety Angioplasty is common and generally safe. It is still a procedure on the heart, and it carries real risks that deserve honest discussion. More common problems include bruising, bleeding, or soreness at the access site. Contrast dye can also cause a temporary drop in kidney function. That is more likely when kidney disease or diabetes is already present. Allergic reactions to dye can occur and are usually treatable. Less common risks include an abnormal heart rhythm, injury or tearing of the artery, and stroke. The procedure can also trigger a heart attack or create a need for emergency bypass surgery. Serious complications are uncommon in stable patients, and more likely in emergencies or in people who are already very ill. Over time, an artery can narrow again inside or around the stent, a process called restenosis. Modern drug-coated stents have made this much less frequent. A stent can also clot suddenly, which is why the antiplatelet medications matter so much. Call 911 for new severe chest pain. Call the office for bleeding, swelling, fever, or a spreading bruise at the access site.

Painless, 15 to 30 minutes, results same day. What is the Ankle-Brachial Index? The ankle-brachial index, or ABI, is a simple painless test. It compares the blood pressure measured at your ankle with the blood pressure measured at your arm. In a healthy circulation the two pressures are close to equal. When arteries in the legs are narrowed by plaque, pressure at the ankle drops. The ratio between the two numbers then falls below normal. That is why the ABI is the standard first test for peripheral artery disease, often shortened to PAD. In that condition, the arteries carrying blood to the legs become narrowed. The test uses ordinary blood pressure cuffs and a small handheld Doppler ultrasound probe. The probe listens to the pulse. Nothing is injected, no radiation is used, and no needles are involved. The test is done in the office in roughly 15 to 30 minutes. Dr. Vimal Nanavati can review the numbers with you the same day. Why Dr. Nanavati may recommend this Peripheral artery disease is common, often silent, and an important marker of risk elsewhere in the body. Someone with narrowed leg arteries frequently has narrowing in the heart and neck arteries too. The American Heart Association describes peripheral artery disease and its symptoms, and MedlinePlus offers a plain language overview. Screening for PAD is part of our broader cardiology services. Dr. Nanavati may recommend an ABI if you have: - Cramping, aching, or heaviness in the calf, thigh, or buttock that starts with walking and eases with rest, a symptom called claudication. - Leg pain at rest, especially at night, or pain that improves when you dangle your leg over the bed. - A sore, ulcer, or wound on the foot or toes that is slow to heal. - Cold feet, weak or absent foot pulses, hair loss over the shins, or shiny skin on the legs. - Diabetes, kidney disease, high blood pressure, or a history of smoking. - Known coronary artery disease or narrowing found on a carotid ultrasound. - A need to check how well treatment for PAD is working over time. How to prepare Very little preparation is needed, and you can eat normally. - Wear loose clothing, or pants that can be rolled above the knee. You may be asked to change into shorts or a gown. - Skip knee-high compression stockings on the day of the test. - Avoid nicotine and caffeine for a few hours beforehand. Both temporarily tighten blood vessels and can shift the reading. - Take your regular medications, including blood pressure pills, unless told otherwise. Bring your list so the results can be read in context. - Tell the office if you have a wound, graft, or recent surgery on an arm or leg. Mention a mastectomy with lymph node removal too, since a cuff may need to be placed differently. - Plan to rest quietly for about 10 minutes before the measurements begin. Walking in from the parking lot right before the test can lower the numbers. - Allow about 30 minutes, or up to an hour if exercise testing is added. What happens during the procedure You lie flat on your back on an exam table, with your head and heels supported. You rest quietly for several minutes so your blood pressure settles. Blood pressure cuffs are placed on both upper arms and both ankles. A small amount of clear gel goes over the pulse points. A handheld Doppler probe is then held gently against the skin. The probe turns blood flow into an audible whooshing sound. That sound tells the technician exactly when flow returns as the cuff deflates. Each cuff is inflated briefly and then released. You feel the familiar squeeze of a blood pressure cuff and nothing more. Several readings are taken at each site, including two different arteries at each ankle. The highest ankle pressure on each side is divided by the higher of the two arm pressures. That ratio is your ABI, calculated separately for the right and left leg. Sometimes the test is repeated after walking on a treadmill for a few minutes. Exercise can unmask a narrowing that looks normal at rest. If your arteries are stiff and hard to compress, a toe pressure may be measured instead. Recovery and results There is no recovery. The gel is wiped off and you get dressed. You can drive, work, and exercise immediately. Results are available right away, because the calculation is simple arithmetic. In general, a resting ABI between about 1.0 and 1.4 is normal, 0.91 to 0.99 is borderline, and 0.90 or lower supports a diagnosis of peripheral artery disease. Lower numbers suggest more severe narrowing. A value above 1.4 usually means the arteries are calcified and too stiff to compress. That pattern is common in diabetes and kidney disease, and it calls for a toe-brachial index instead. Dr. Nanavati interprets the number alongside your symptoms and examination. Mild disease is usually managed with a structured walking program and smoking cessation. Cholesterol and blood pressure control and diabetes care matter just as much. More significant findings may lead to an arterial Doppler ultrasound to map the narrowing. Occasionally they lead to a catheter-based procedure. Risks and safety The ABI is one of the safest tests available. There are no needles, no dye, no radiation, and no medication. The only real discomfort is the pressure of the cuff. Some people find it briefly uncomfortable, particularly at the ankle. Tell the technician if you have a painful leg ulcer, fragile skin, or a recent bypass graft. The cuff can then be placed carefully, or the test modified. If exercise testing is added, walking may bring on the leg cramping you already experience. The treadmill is stopped as soon as you ask, and the discomfort resolves with rest. The main limitation is accuracy rather than safety. Stiff calcified arteries can produce a falsely normal or falsely high value. So a normal ABI does not always rule out disease when symptoms are convincing. In that situation additional imaging is used rather than relying on the number alone.

Painless, no radiation or dye. What is an Arterial Doppler Ultrasound? An arterial Doppler ultrasound follows blood on its way out from the heart. Arteries are the vessels that carry oxygen-rich blood to the limbs and organs. When plaque narrows one of them, the tissue downstream receives less than it needs. This painless test finds the narrow spot and shows how tight it is. A small handheld device called a transducer is pressed against the skin over the artery. It sends sound waves into the body and listens for the echoes that bounce back. A computer builds two things from those echoes. One is a picture of the vessel. The other is a graph of how fast blood is moving. Color Doppler adds color for the direction of flow, which makes a blocked segment easy to spot. Most requests involve the legs, since that is where poor flow causes symptoms you can feel. The test uses no radiation, no needles, and usually no dye. The study is done in the office by a trained sonographer. It takes roughly 30 to 60 minutes, depending on how much of the body is examined, and needs no recovery time. Arterial studies are one branch of the wider vascular ultrasound family. The neck arteries have a study of their own, the carotid ultrasound and Doppler. The veins are checked with a venous ultrasound, which hunts for different problems entirely. Why Dr. Nanavati may recommend this Arterial Doppler ultrasound answers two practical questions. Is blood flow to a limb or organ reduced? If so, exactly where is the problem? Dr. Nanavati may recommend it if you have: - Leg cramping or aching that begins with walking and stops with rest, the classic symptom of peripheral artery disease. The American Heart Association explains peripheral artery disease and why it matters. - An abnormal or borderline ankle-brachial index that needs to be mapped in more detail. - A foot or leg wound that will not heal, or foot pain at rest. - Coldness, numbness, weakness, or color change in an arm or leg. - A pulsating mass in the abdomen, or screening for an aortic aneurysm, which is a bulge in a weakened artery wall. - Suspected narrowing of a kidney artery in someone with hard to control blood pressure. - Follow-up of a previous bypass graft, stent, or dialysis access to make sure it is still open. The National Heart, Lung, and Blood Institute reviews how reduced circulation is diagnosed and treated. How to prepare Preparation depends on which arteries are being studied, so follow the instructions the office gives you. - For arm and leg studies, no fasting is needed. Eat, drink, and take your medications as usual. - For studies of the abdominal aorta or the kidney arteries, expect to skip food for about 8 hours beforehand. Gas and food in the bowel obscure the picture. Sips of water with pills are generally fine. - Do not smoke or use nicotine for at least two hours before the test. Nicotine narrows blood vessels and can distort the measurements. - Wear loose, two piece clothing that is easy to remove. You may be given a gown. - Leave necklaces and other jewelry at home when the neck or chest is being scanned. - Keep taking blood thinners and blood pressure medications unless specifically instructed otherwise. - Allow about an hour for the appointment. What happens during the procedure Where the probe travels depends on which artery is in question. The study is shaped around your symptoms. For a leg study you lie on your back. The leg is straightened and rolled slightly outward. The sonographer starts high, at the groin, and works downward. The femoral artery in the thigh comes first. Next is the popliteal artery behind the knee, which usually means bending or turning the leg. After that come the vessels running down the calf toward the ankle. Each segment is sampled in turn. A leg study is a series of short stops rather than one long sweep. Both legs are usually examined. Comparing the two sides is how mild narrowing on one side becomes obvious. Gel is spread on the skin ahead of the probe. It feels cool, and it clears away the thin layer of air that sound waves cannot cross. Listen to the speakers. A healthy leg artery makes a sharp, snapping sound with each heartbeat. Past a tight segment that sound flattens into a softer hum. The tracing on the screen changes shape along with it. Your sonographer is listening for exactly that change. Arm studies follow the same idea, working down from the shoulder. Abdominal studies are different. There the probe presses in more firmly to push bowel gas out of the way. You may be asked to take a breath and hold it while an image is captured. That pressure can feel uncomfortable, but it should not be painful. Say something if it is. This scan often runs alongside an ankle-brachial index, which compares the blood pressure at your ankle with the pressure at your arm. The two tests answer different halves of one question. The index says how much flow is reduced overall. The ultrasound says where the blockage sits. Recovery and results You are free to go as soon as you are dressed. Normal activity resumes at once, with no limits on driving, work, or exercise. If you fasted for an abdominal study, bring a snack for afterward. A physician reviews and interprets the images. Dr. Nanavati typically has the written report in hand a few days later. In some situations the sonographer can flag an urgent finding right away. Dr. Nanavati then explains the results at a follow-up appointment or by phone. A normal study means the arteries are open and blood is moving at expected speeds. An abnormal study describes where the narrowing sits and how severe it is. Severity is graded by how much the flow speeds up as it squeezes through the tight segment. Mild to moderate disease is usually treated without a procedure. A supervised walking program is the cornerstone. Stopping smoking, controlling cholesterol, and controlling blood pressure come next, and medication is sometimes added. Advanced lipid testing can help when your risk is unclear. Severe disease is handled differently. So is a wound that will not heal, or pain in the foot at rest. Those situations may lead to further imaging and to a catheter-based procedure such as angioplasty. Risks and safety Nothing about this study is invasive. No needle goes in, nothing is swallowed, and no dye is given. There is no radiation, so there is no dose to add up across repeat scans. Comfort depends mostly on where the probe has to go. A leg study is easy for the large majority of people. Tenderness shows up over a bruise, an inflamed vein, or a healing surgical site, and the sonographer can lighten the pressure or work around the spot. Abdominal scanning needs a firmer push and is the part people tend to mention afterward. A full map of both legs can also run close to an hour. That is a long time to lie flat with a sore back or hip, and a pillow under the knees usually solves it. The limits are worth understanding, because they turn up in exactly the patients who need this test. Long standing diabetes and kidney disease can leave artery walls heavily calcified. Calcium reflects sound, so those segments are hard to grade. Open wounds, dressings, and casts sit between the probe and the artery, and the scan cannot see through them. Bowel gas does the same to the abdominal vessels, which is why fasting is asked for. When part of the picture is missing, CT or MR angiography usually fills it in. Remember too that this is a snapshot of one moment at rest. Symptoms that come and go may still need further evaluation.

What it involves, who benefits, and what to expect. What is Cardiac Rehabilitation? Cardiac rehabilitation is a medically supervised program. It helps people recover after a heart attack, a heart procedure, or a diagnosis such as heart failure. It combines three things. The first is monitored exercise that is built around your own capacity. The second is education about medications, nutrition, and risk factors. The third is counseling for the anxiety and low mood that often follow a cardiac event. Sessions take place in a facility with staff trained in cardiac emergencies. Your heart rhythm and blood pressure are watched while you exercise. A typical program runs two or three sessions a week for about 12 weeks, often 36 sessions in total. The length is adjusted to your needs. Cardiac rehabilitation is not simply a gym membership. It is a structured treatment that is proven to reduce hospital readmissions and improve survival. Dr. Vimal Nanavati refers patients to accredited hospital-based programs. He coordinates care with the rehabilitation team throughout. Why Dr. Nanavati may recommend this The weeks after a cardiac event are when habits are most changeable. They are also when the risk of a second event is highest. Rehabilitation uses that window deliberately. The American Heart Association explains what cardiac rehab involves and why it is recommended, and MedlinePlus reviews the evidence behind cardiac rehabilitation. Dr. Nanavati may recommend cardiac rehabilitation after: - A heart attack, whether or not a stent was placed. - Angioplasty or coronary stenting - Coronary artery bypass surgery, valve repair, or valve replacement. - A diagnosis of stable angina or coronary artery disease. - A diagnosis of chronic heart failure with reduced pumping strength. - A heart transplant, or placement of a mechanical support device. - Treatment for peripheral artery disease that causes leg cramping with walking. It is also worth considering if you have become fearful of exertion. Many people are afraid to raise their heart rate after a cardiac event. Doing it under monitoring, with staff nearby, rebuilds confidence faster than anything you can do alone. How to prepare - Get the referral in place before you leave the hospital if you can. Starting within a few weeks of the event gives the best results. - Expect a baseline evaluation. It usually includes a history, an examination, an electrocardiogram, and sometimes an exercise test to set safe target intensities. - Bring a complete list of your medications and doses to the first visit. Bring your recent hospital discharge papers as well. - Wear comfortable athletic clothing and supportive closed-toe shoes. Loose layers make it easier once you warm up. - Bring a water bottle. If you have diabetes, bring a fast-acting carbohydrate and your glucose meter. - Eat a light meal one to two hours before a session. Avoid exercising on an empty stomach or right after a large meal. - Plan your schedule realistically. Sessions usually last about an hour, plus travel time, two or three times a week. - Tell the team about joint problems, balance issues, or lung disease, so the exercise plan can be adapted. What happens during the procedure Cardiac rehabilitation is a program rather than a single procedure. Here is what a typical session looks like. You check in and the staff record your blood pressure, heart rate, weight, and often your blood sugar. They ask how you have felt since the last session. Tell them about any chest discomfort, shortness of breath, dizziness, or swelling. Electrodes are placed on your chest. Your heart rhythm can then be displayed on a monitor while you exercise. You warm up gently and move through a circuit. It may include a treadmill, a stationary bike, a rowing machine, an arm ergometer, and light resistance training. Intensity is set from your baseline test, and it increases gradually as you improve. Staff check in with you continually. They use a simple scale to ask how hard the work feels. A cool-down and stretching period follows. Many sessions include a short education segment. Topics include reading food labels, sodium, cholesterol, medication adherence, smoking cessation, or managing stress. Some programs also offer individual dietitian and psychology visits. Nothing about the session should feel punishing. Steady, repeatable effort is the goal. Recovery and results Progress in cardiac rehabilitation is measured in weeks, not days. Most people notice they can walk further with less breathlessness within three to four weeks. Strength, sleep, and mood usually follow. The team tracks objective measures such as exercise capacity, blood pressure, weight, and cholesterol. They also repeat an exercise assessment near the end of the program. That report is sent back to Dr. Nanavati. He uses it to adjust medications and to set your long term activity plan. Graduating from the program is the beginning rather than the end. You will leave with a written home exercise prescription and target heart rate or effort ranges. You will also have a plan for continued follow-up. Many programs offer a maintenance phase you can continue at lower cost. Keeping up the routine matters, because the benefits fade if activity stops. Ongoing risk factor work continues through our office, including advanced lipid testing and blood pressure control. Risks and safety Exercise after a heart event feels risky, and that concern is reasonable. In practice, supervised cardiac rehabilitation is very safe. Serious cardiac events during monitored sessions are rare. The setting is specifically designed to catch problems early, with trained staff, continuous rhythm monitoring, and emergency equipment on site. The common issues are ordinary ones. Muscle soreness, fatigue in the first week or two, and occasional joint aches are typical, and the program adjusts to them. People with diabetes can see blood sugar drop with exercise. That is why glucose is checked and snacks are available. Stop and tell staff immediately if you have chest pressure, unusual shortness of breath, lightheadedness, palpitations, or a cold sweat. Programs are also cautious about starting or continuing sessions when blood pressure is very high or very low. The same is true when an infection is active, or when arrhythmias are unstable. Not everyone can start right away. Unstable angina, uncontrolled heart failure, or a severe valve problem may need treatment first. Dr. Nanavati will tell you when it is safe to begin.

What are Cardiology Services? Cardiology services are the tests, treatments, and ongoing care for the heart and blood vessels. They evaluate problems and then manage them over time. A cardiologist is a physician with additional training in this system. An interventional cardiologist has further training in catheter-based procedures that open blocked arteries. In practice, cardiology care follows a path. It begins with a consultation and a physical examination. Testing comes next, and it measures the heart's electrical activity, structure, and blood supply. A treatment plan follows, and it may involve lifestyle change, medication, a procedure, or a combination. Prevention is a large part of the work. Managing blood pressure, cholesterol, and diabetes prevents more heart attacks than any procedure does. Dr. Vimal Nanavati, MD, FACC, is board certified in both cardiology and interventional cardiology. He has 32 years of experience, and he founded HeartCare4life, also known as Advanced Heart Care, Inc., in 1997. Why Dr. Nanavati may recommend this Some people are referred by a primary care physician. Others come on their own, because something does not feel right. Both are appropriate. Consider seeing a cardiologist if you have: - Chest pain, pressure, or tightness, especially with exertion. Sudden or severe chest pain is an emergency, so call 911. - Shortness of breath with activity, or breathlessness when lying flat. - Heart palpitations, a racing pulse, or a skipped or irregular beat. - Fainting, near-fainting, or unexplained dizziness. - A heart murmur, an extra sound heard on examination. - High blood pressure or high cholesterol that is difficult to control. - Diabetes, which raises cardiovascular risk substantially. - A family history of early heart attack, stroke, or sudden death. - Swelling in the legs or ankles, or a sharp drop in exercise tolerance. - A known heart condition that needs ongoing management. Heart disease remains the leading cause of death in the United States. That is the finding reported by the Centers for Disease Control and Prevention. The American Heart Association outlines the risk factors that can be changed. How to prepare - Bring every medication and supplement you take, in the bottles if possible, including doses. - Bring records of previous heart testing, hospital discharge summaries, and recent laboratory results. - Write down your symptoms in advance. Note what brings them on, how long they last, and what relieves them. - Note your family history, particularly heart disease, stroke, or sudden death in parents or siblings before age 60. - Wear a two piece outfit. You may need to undress from the waist up for an examination or a test. - Ask when you book whether testing may be done the same day. Some tests require fasting or avoiding caffeine. - Write down your questions. It is easy to forget them once the visit starts. - Bring a family member if you would like a second set of ears. What happens during the procedure A first cardiology visit is a conversation followed by an examination, not a procedure. Dr. Nanavati reviews your symptoms in detail, along with your medical history, your medications, and your family history. Habits count too, such as smoking, alcohol, activity, and sleep. Small details matter here. The pattern of a symptom often points to its cause more clearly than any single test. The examination covers blood pressure in both arms, along with your pulse and weight. Dr. Nanavati listens to the heart and lungs. He checks the neck veins and the pulses in the arms, legs, and abdomen, and he looks for swelling. Testing answers a specific question rather than arriving as a package. In-office diagnostics include the electrocardiogram, echocardiography, and stress testing. We also offer vascular ultrasound such as the carotid Doppler, Holter monitoring, and advanced lipid testing. Other procedures happen elsewhere: coronary stenting and left atrial appendage closure are done at affiliated hospitals, not in the office. You leave with an explanation of what is likely going on. You will also know what will be tested and what happens next. Recovery and results There is nothing to recover from after a consultation. You can drive and return to work directly, unless a test that day required sedation. Results arrive on different schedules. An electrocardiogram is read immediately. An echocardiogram or vascular ultrasound is usually reported within a few days. Advanced laboratory panels and monitor downloads can take one to two weeks. You will be told which results to expect and roughly when. Follow-up depends on what is found. Stable, well-controlled conditions are often reviewed every 6 to 12 months. A new symptom, a medication change, or a recent procedure calls for closer follow-up. We coordinate care with your primary care physician, so that everyone works from the same plan. Our Bonita office is at 180 Otay Lakes Rd Ste 110, Bonita, CA 91902, phone (619) 585-0476. We also see patients at 5190 Governor Dr, San Diego, CA 92122. Our Redding office is at 2510 Airpark Drive Ste 205, Redding, CA 96001, phone (530) 433-5427. Details for each are on our locations page. Risks and safety A consultation carries no physical risk. The tests that follow range from completely harmless to modestly invasive. Dr. Nanavati discusses each one with you before it is arranged. Noninvasive tests such as electrocardiography, echocardiography, and vascular ultrasound involve no radiation, no needles, and no recovery. Blood tests carry the small risks of any blood draw. Some imaging tests use radiation or contrast dye. Coronary CT angiography and nuclear stress testing are two examples. They carry a small radiation exposure, plus a small risk of allergic reaction or kidney effects from the dye. Catheter-based procedures carry the highest risk, including bleeding, artery injury, and rarely heart attack or stroke. The honest principle is simple: a test should only be done when its result will change what happens next. Being clear about that keeps risk and cost proportionate to benefit. Ask directly what a proposed test will show, and what will be done with the answer.

Painless, about 30 minutes, no radiation. What is a Carotid Ultrasound? A carotid ultrasound is a painless test of the two large arteries in your neck. These are the carotid arteries. They run up either side of the neck and carry blood to the brain. A small handheld probe rests on the skin over each one. It sends high frequency sound waves into the tissue. The echoes return as a live picture of the artery wall. The same probe also measures how fast the blood is moving. Speed matters here. Blood speeds up as it squeezes through a tight spot. That lets your cardiologist find plaque and judge how much it narrows the channel. Plaque is the fatty deposit that builds up inside artery walls. The test is often called a carotid Doppler. It uses no radiation, no dye, and no needles. It is safe to repeat and safe in pregnancy. The scan takes about 30 minutes, is done in the office, and needs no recovery time. Carotid, arterial, and venous scans all belong to the vascular ultrasound family. What sets this one apart is the target. It looks at the blood supply to your brain, so the question behind it is stroke risk. The arterial ultrasound covers the arms and legs instead. The venous ultrasound covers the veins, which fail in a different way. Why Dr. Nanavati may recommend this Narrowing of a carotid artery is a treatable cause of stroke. Plaque can restrict the flow of blood. Small fragments can also break loose and travel to the brain. Finding this early allows treatment before a stroke happens. Dr. Nanavati may recommend a carotid ultrasound if you have: - A transient ischemic attack, sometimes called a mini-stroke, or a previous stroke. - Sudden temporary weakness, numbness, slurred speech, or loss of vision in one eye. - A bruit, which is a whooshing sound heard through a stethoscope over the neck artery. - Known coronary artery disease, or plaque found elsewhere on an arterial ultrasound. - High blood pressure, high cholesterol, diabetes, or a history of smoking. - A family history of stroke or early heart disease. - A previous carotid procedure that needs periodic surveillance. The American Stroke Association describes stroke warning signs. MedlinePlus provides an overview of carotid artery disease. Stroke symptoms are an emergency. Call 911 rather than waiting for a scheduled test. How to prepare There is almost nothing to do, which is one of the advantages of this test. - Eat and drink normally. No fasting is required. - Take all of your medications as usual, including blood thinners and blood pressure pills. - Wear a shirt with an open collar or no collar. A turtleneck makes the study awkward. - Leave necklaces, scarves, and long dangling earrings at home, or plan to remove them. - Skip perfume, cologne, and heavy moisturizer on the neck that morning. - Tell the office about neck pain, limited neck movement, or recent neck surgery. Positioning can be adjusted. - Allow about 45 minutes for check-in and the scan itself. - Bring your medication list and any prior imaging reports of the neck arteries for comparison. What happens during the procedure Position is the part of this test that people notice most. You lie flat on your back. A pillow often goes under your shoulders. That tips the chin up and opens the space along the side of the neck. Your head is then turned gently away from the side being scanned. The room lights are dimmed so the screen reads clearly. Your collar is folded down, or you change into a gown. The neck has to be bare from the collarbone up to the jaw. Gel goes on one side of the neck at a time. The probe follows a short and well defined route. It starts low, near the collarbone. It travels up along the common carotid artery. It pauses at the fork where that artery splits into its internal and external branches. Plaque tends to collect at the fork, so the sonographer spends extra time there. Sound is part of this study. The speakers carry a pulsing tone that rises and falls with your heartbeat. That is your own blood on its way to your brain. Swallowing and talking move the neck. You may be asked to hold off for a few seconds while a measurement is captured. You may also be asked to turn your head a little further to open the angle. Pressure from the probe stays light throughout. Tell the sonographer if anything hurts. The whole route is then repeated on the other side. The vertebral arteries at the back of the neck are usually checked as well. When the images are complete, the gel is wiped away. Recovery and results Nothing needs to wear off. You wipe away any leftover gel, get dressed, and carry on with your day. Driving, work, and exercise are all fine right away. A physician reads the images. The report usually reaches Dr. Nanavati within a few days. Urgent findings are passed along sooner. He then reviews the results with you and explains what they mean for your care. Carotid results are reported as a percentage range of narrowing. The common bands are less than 50 percent, 50 to 69 percent, and 70 percent or greater. That number drives what happens next. Mild narrowing is usually managed with medication and risk factor control. That means lowering cholesterol, controlling blood pressure and blood sugar, and stopping smoking. Antiplatelet medication is sometimes added. Advanced lipid testing can help guide those choices. Moderate narrowing is watched with repeat ultrasound, often every 6 to 12 months. Severe narrowing is treated differently, especially if you have had symptoms. It may lead to confirmatory imaging. It may also lead to a referral to discuss a procedure to open or bypass the artery. Risks and safety There is essentially nothing to weigh against this test. Sound at diagnostic levels does not harm tissue. Nothing is injected, no dye is used, and no radiation dose is added. You leave with no restrictions of any kind. The complaints we hear are about the neck. Holding your head turned to one side for several minutes can tire a stiff neck or a sore shoulder. The pillow can be moved, and the scan can be done in shorter stretches. Cool gel is the other common complaint, and it wipes off at the end. What matters more is knowing what this scan can miss. Plaque that has hardened with calcium reflects sound instead of letting it pass. That casts a shadow, and the segment hidden behind the shadow cannot be graded. A carotid artery that branches unusually high can also be hard to reach. So can one that sits deep behind a short neck. When part of the artery cannot be seen, or when the pictures do not match your symptoms, CT or MR angiography is the usual next step. A clean carotid study is reassuring, but it answers one question only. Stroke has other causes. Atrial fibrillation throws clots to the brain from the heart rather than from the neck, and it calls for a different workup.

Preparation, procedure, and results. What is Coronary CT Angiography? Coronary CT angiography is a noninvasive imaging test, usually shortened to CCTA or called a heart CT scan. It produces detailed pictures of the coronary arteries, the vessels that supply blood to the heart muscle. A small intravenous line in the arm delivers contrast dye. A CT scanner then takes rapid X-ray images timed to your heartbeat as the dye passes through. A computer assembles those images into a three dimensional picture of each artery. This shows plaque, the buildup inside artery walls, and how much it narrows the channel. Unlike a traditional coronary angiogram, no catheter is threaded to the heart, and there is no incision. The scan itself lasts only seconds, though the full appointment usually runs one to two hours because of preparation. You are awake throughout and go home the same day. Dr. Vimal Nanavati uses the result to decide whether medication or a procedure is the better next step. Why Dr. Nanavati may recommend this CCTA is particularly good at ruling coronary disease out. A normal scan is powerful reassurance, which makes it valuable when symptoms are ambiguous. Dr. Nanavati may recommend it if you have: - Chest pain, pressure, or jaw, neck, or arm discomfort that could be cardiac in origin. - Unexplained shortness of breath or reduced exercise tolerance. - An inconclusive or borderline stress test result. - An intermediate risk of coronary artery disease where the decision to treat is not clear cut. - A need to evaluate the arteries before certain heart or valve procedures. - A previous bypass graft that needs assessment. The American Heart Association explains how coronary artery disease develops and what raises risk. The National Heart, Lung, and Blood Institute reviews coronary heart disease diagnosis. CCTA is not the right test during an active heart attack. That situation calls for emergency care, and usually a catheter procedure such as angioplasty. How to prepare Preparation matters here, since image quality depends on a slow, steady heart rate. - Do not eat for about four hours before the scan. Clear fluids and water are usually allowed and help protect the kidneys. - Avoid all caffeine for 12 hours beforehand, including coffee, tea, soda, energy drinks, and chocolate. Caffeine speeds the heart and blurs the images. - Ask about beta blocker medication. Many patients get a dose before the scan, or at the facility, to slow the heart rate. - Tell the team if you take sildenafil, tadalafil, or a similar medication for erectile dysfunction or pulmonary hypertension. These must not be combined with the nitroglycerin used during the scan. A waiting period is required. - Report any allergy to contrast dye or iodine, any kidney disease, and any history of asthma. A blood test of kidney function is often done first. - Ask about metformin, which is sometimes held after contrast is given. - Wear clothing without metal, leave jewelry at home, and expect to change into a gown. - Tell the team if you are or might be pregnant. Also allow one to two hours for the visit. What happens during the procedure A nurse places a small intravenous line in a vein in your arm. Electrodes go on your chest so the scanner can time its pictures to your heartbeat. The team also checks your heart rate and blood pressure. Your heart rate may be above roughly 60 beats per minute. If so, you are given medication to slow it, either by mouth or through the line. A small nitroglycerin tablet or spray usually goes under the tongue just before the scan to widen the coronary arteries. This commonly causes a brief headache or flushing. You lie on your back on a moving table with your arms above your head. The table slides into a short open ring, not a long tunnel, so most people who dislike enclosed spaces tolerate it well. You practice a breath hold first. When the scan runs, the contrast is injected through the line. You hold your breath for roughly five to ten seconds while the images are captured. The dye often produces a warm rush through the chest and a metallic taste. Many people feel as though they have wet themselves. That sensation is normal and passes in under a minute. The scanning itself is over in seconds. A nurse removes the line afterward. Recovery and results You can return to normal activity immediately, including driving and work. The exception is if you were given a strong sedative. A beta blocker may leave you a little tired or lightheaded for a few hours. Stand up slowly. Drink extra water for the rest of the day. This helps your kidneys clear the contrast. A physician trained in cardiac CT interprets the images. Reports usually reach Dr. Nanavati within a few days. He then reviews them with you. A normal scan means the arteries are open, and the likelihood of a heart attack in the near term is very low. Mild or moderate plaque usually leads to prevention. That means cholesterol lowering, blood pressure and blood sugar control, and exercise. It often means advanced lipid testing to refine risk. A severe narrowing may lead to functional testing such as advanced stress testing. It may also lead to a coronary angiogram and possible coronary stenting. Risks and safety CCTA is safe for most people, but it is not free of risk. The two main considerations are radiation and contrast dye. The scan uses ionizing radiation. Modern scanners and dose-reduction techniques have cut exposure substantially. The dose is comparable to other common medical imaging. A small theoretical long term risk remains, which is why the test is ordered when it will genuinely change management. It is generally avoided in pregnancy. Iodinated contrast can cause an allergic reaction. Most reactions are mild, such as hives or itching. Severe reactions are rare but treatable. Contrast can also stress the kidneys, a greater concern in people with existing kidney disease, diabetes, or dehydration. Kidney function is checked beforehand, and fluids are encouraged. The medications used carry their own minor effects. Beta blockers can slow the heart rate and lower blood pressure. Nitroglycerin frequently causes headache and flushing. Call the office for spreading redness, swelling, or pain at the intravenous site. Call 911 for chest pain or trouble breathing. Related services and conditions - Advanced stress testing when blood flow needs measuring. - Coronary artery disease and chest pain. - IHD evaluation, the broader ischemic workup. - Coronary stenting if a severe narrowing is confirmed. ## Coronary Stenting URL: https://www.heartcare4life.com/services/coronary-stenting Summary: A coronary stent is a small mesh tube that holds a heart artery open after angioplasty. Why it is placed, how to prepare, recovery, and the medications after. What is Coronary Stenting? Coronary stenting places a small expandable metal mesh tube inside a heart artery, where it holds the vessel open after a blockage has been widened. A tiny balloon stretches the blockage open first, a step called angioplasty. The stent then travels to the same spot on a balloon catheter, and it expands until it presses firmly into the artery wall, where it stays permanently. Within weeks the artery lining grows over the mesh, making it part of the vessel. Most stents used today are drug-eluting. That means they carry a medication coating, released slowly to discourage scar tissue from narrowing the artery again. Stenting is done through a catheter inserted at the wrist or groin, so there is no chest incision. The work happens in a hospital catheterization laboratory rather than in the office. Dr. Vimal Nanavati is board certified in interventional cardiology, and he performs these procedures at affiliated hospitals. Why Dr. Nanavati may recommend this A stent restores blood flow through a narrowed artery. It also keeps that artery from closing back down after the balloon is removed. Dr. Nanavati may recommend coronary stenting if you have: - An active heart attack, where reopening the artery quickly limits damage to the heart muscle. The American Heart Association describes heart attack warning signs, and calling 911 is always the first step. - Chest pain with exertion that persists despite medication. - A severe narrowing shown on a coronary angiogram or on coronary CT angiography. - A large area of reduced blood flow on stress imaging. - Symptoms of coronary artery disease that limit your daily life. Not every blockage needs a stent. For stable symptoms, medication and risk factor treatment often work just as well. Bypass surgery is sometimes the better treatment for multi-vessel disease. The National Heart, Lung, and Blood Institute reviews the treatment options for coronary heart disease. Dr. Nanavati will explain why a stent is or is not the right choice in your case. How to prepare - Expect preliminary testing, which usually includes blood work, an electrocardiogram, and imaging of the heart. - Do not eat or drink after midnight, or follow the specific instructions you are given. Essential pills may be taken with a sip of water. - Ask about blood thinners, diabetes medication, and metformin. Some are held, and some are deliberately continued. Never adjust them on your own. - Report allergies to contrast dye, iodine, shellfish, latex, or any medication, and tell the team about kidney disease. - Arrange for an adult to drive you home and stay with you for the first night. - Pack an overnight bag, your medication list, and your insurance information in case you stay. - Leave jewelry at home. - Plan to spend most of the day at the hospital. What happens during the procedure You lie on a narrow table beneath a movable X-ray camera. Monitors track your heart rhythm, blood pressure, and oxygen, and an intravenous line goes in for fluids and medication. You stay awake but relaxed. A mild sedative is usual, so many people remember little afterward. The team cleans, drapes, and numbs the wrist or groin with local anesthetic. You may feel pressure while the sheath is placed, but not sharp pain. A thin catheter is guided through the artery to the heart. This is not painful, because arteries have no internal sensory nerves. Contrast dye is then injected so the arteries appear on the screen, and you may feel a brief warm flush. A soft guidewire is passed across the blockage. The balloon inflates to open the narrowing. Some people feel this as several seconds of chest pressure that fades as the balloon deflates. The stent sits collapsed on a second balloon, and it is advanced to the same spot and expanded into place. The balloon is deflated and removed. The stent stays. Final pictures confirm the artery is open. The catheter is withdrawn, and a closure device or firm pressure seals the access site. Recovery and results If the wrist was used, a compression band stays on for a few hours, and you can sit up soon after. If the groin was used, you lie flat for several hours to prevent bleeding. Stable patients often go home the same day, while a heart attack usually means several days in the hospital. The result is known immediately. Your cardiologist sees the open artery on screen, and will explain what was found and what was done. At home, keep the access site clean and dry, and avoid heavy lifting, straining, and vigorous exercise for about a week. Many people return to desk work within a few days. Chest pain related to the blockage often improves quickly. The most important part of recovery is medication. You will take aspirin plus a second antiplatelet drug. Together these are known as dual antiplatelet therapy. You stay on them for a period your cardiologist specifies. Stopping these early is the single biggest cause of sudden stent clotting. Never stop them without checking first, including before dental work or surgery. Cardiac rehabilitation is strongly recommended afterward. Modern coronary stents are generally considered safe for MRI scanning. The rules vary, though, by device and by how recently the stent was placed. Always tell the MRI facility that you have a stent and when you received it. Risks and safety Coronary stenting is common and generally safe. Even so, the risks deserve a plain description. Bruising, bleeding, or soreness at the access site is the most frequent problem. Contrast dye can temporarily reduce kidney function. That is a greater concern with existing kidney disease or diabetes. The dye can also cause allergic reactions, which are usually mild and treatable. Other risks are less common but more serious. They include an abnormal heart rhythm, tearing or injury of the coronary artery, and a heart attack triggered by the procedure. Stroke is possible, and rarely emergency bypass surgery is needed. Serious complications are uncommon in stable patients. They are more likely during emergencies, or in people who are already critically ill. Two longer term issues are specific to stents. Restenosis is gradual renarrowing from scar tissue inside the stent. It is now much less frequent with drug-eluting stents. Stent thrombosis is a sudden clot inside the stent. It is rare but dangerous. That is why the antiplatelet medications matter so much. Call 911 for new severe chest pain. Call the office for fever, spreading bruising, swelling, or bleeding at the access site.

It reads battery life, lead function, recorded rhythms, and any shocks given. What is Defibrillator Interrogation? Defibrillator interrogation is a painless office check of an implantable cardioverter-defibrillator, usually called an ICD. An ICD is a small device placed under the skin of the chest. It watches your heart rhythm continuously. If a dangerous rhythm develops, it delivers a pacing burst or an electrical shock. Interrogation is the process of reading what that device has recorded. A specialized programmer is held over the skin above the device, and the two communicate wirelessly. The report shows remaining battery life and how well the leads or wires are working. It also lists every abnormal rhythm the device has stored, along with any therapy it delivered. Settings can be adjusted at the same visit if your rhythm or your medications have changed. Nothing is injected and no needle is used. The check takes about 15 to 30 minutes, and you can drive yourself home afterward. Dr. Vimal Nanavati reviews the findings with you before you leave. Why Dr. Nanavati may recommend this An ICD is a safety net, and a safety net needs checking. Interrogation confirms that the device will work when you need it. It also gives a detailed record of what your heart has been doing between visits. Interrogation is recommended: - On a regular schedule, commonly every three to six months, sometimes alternating with remote transmissions from home. - Promptly after the device delivers a shock, or after you hear an audible alert or feel a vibration. - When you have new symptoms such as heart palpitations, dizziness, fainting, or unusual fatigue. - After implantation, generator replacement, or any lead revision. - When remote monitoring flags an abnormal reading. - When battery depletion or a lead problem is suspected. - Before and after surgery, since electrocautery and some equipment can interfere with the device. - After a change in medication that affects heart rhythm, or after a hospitalization. The American Heart Association explains arrhythmias and the devices used to treat them. MedlinePlus provides an overview of pacemakers and implantable defibrillators in plain language. How to prepare Very little is required, and nothing about your routine has to change. - Eat and drink normally. No fasting is needed. - Take all of your medications as usual, and bring an up-to-date list. - Bring your device identification card, which lists the manufacturer and model. This matters, because each manufacturer uses its own programmer. - Wear a top that opens or lifts easily at the upper chest, such as a button-front shirt. - Write down any symptoms since your last check. Include the date and time of anything that felt like a shock. Timing helps match your experience to the stored recordings. - Bring records from any recent hospital visit or emergency department care. - Allow about 30 to 45 minutes for the appointment. - Your device may transmit from home. If so, make sure the bedside or mobile transmitter has been plugged in and working. What happens during the procedure You sit in a chair or lie on an exam table with your chest accessible. Nothing is placed inside your body, and no part of the check is invasive. A wand is positioned over the skin above your device. Newer systems simply use a nearby antenna. Communication is wireless. Within seconds the programmer displays the device data on screen. The technician or physician then reviews several things in order. First comes battery voltage and the estimated time to replacement, then the electrical measurements of each lead. Next is the percentage of time the device has been pacing, and last is the log of arrhythmias it recorded. Any shock or pacing therapy delivered is shown with the rhythm strip that triggered it. That lets us judge the reason for it. Some devices get a brief test, in which small pacing impulses measure thresholds. Most people feel nothing. A few notice a fluttering or a brief awareness of their heartbeat. It stops as soon as the test does. Settings that need to change are reprogrammed there and then, wirelessly. You feel nothing during reprogramming. No shock is delivered during a routine interrogation. Recovery and results There is no recovery period. You get up and go, and you can drive, work, and exercise immediately. Results are available during the visit. Dr. Nanavati explains the battery status and roughly how long it should last. He also covers whether the leads look healthy and what rhythms the device has recorded. If your ICD delivered a shock, he reviews whether it was appropriate or inappropriate. An appropriate shock treated a genuinely dangerous rhythm such as ventricular tachycardia. An inappropriate one responded to something benign, like a fast rhythm from the upper chambers. What happens next depends on the findings. Stable results usually mean returning to your normal schedule of checks. Recorded arrhythmias may lead to a medication change, an echocardiogram, or a referral for an ablation procedure. A battery nearing depletion is scheduled for generator replacement well in advance, so it is never an emergency. A lead abnormality may need imaging and, occasionally, a revision procedure. Risks and safety Interrogation is among the lowest risk things done in cardiology. The device is only being read and reprogrammed. There is no incision, no needle, no dye, and no radiation. The realistic discomforts are minor. Some people feel a brief flutter during threshold testing. Lying still with the chest exposed can be mildly awkward. Anxiety is common, particularly for people who have received a shock in the past. It helps to say so, since the visit can then be paced more slowly. There is a very small chance that a setting change causes a new sensation, such as awareness of pacing. Report it, since settings can be adjusted again. The important safety points are outside the office. Keep your device identification card with you. Tell any physician, dentist, or surgeon that you have an ICD before a procedure. Keep cell phones and strong magnets away from the device. Avoid leaning over a running engine or industrial equipment with strong electromagnetic fields. Ask before having an MRI, since only certain devices are MRI conditional. If you receive a shock and feel well afterward, call the office promptly. If you receive multiple shocks or feel unwell, call 911.

How to prepare, what to expect, and results. What is an Echocardiogram? An echocardiogram, often shortened to an echo, is a painless ultrasound scan of the heart. A small handheld probe called a transducer is pressed against the chest. It sends high frequency sound waves into the body. Then it listens for the echoes that bounce back from the heart's walls, valves, and moving blood. A computer turns those echoes into a live moving picture. The scan shows the size and thickness of each chamber and how strongly the heart squeezes. It also shows whether the valves open and close properly, whether blood is leaking backward, and whether fluid has collected in the sac around the heart. It measures the ejection fraction too, the percentage of blood pumped out with each beat. There is no radiation, no needles in a standard study, and no recovery time. We perform a routine echocardiogram in our office, and it takes about 30 to 60 minutes. Dr. Vimal Nanavati reviews the images and explains what they show. Why Dr. Nanavati may recommend this An echocardiogram answers structural questions that an electrocardiogram cannot. One measures electricity, the other measures anatomy and movement. Dr. Nanavati may recommend an echocardiogram if you have: - Shortness of breath, swelling in the legs, or reduced exercise tolerance. - A heart murmur, which is an extra sound made by turbulent blood flow across a valve. - Chest pain or pressure that needs a structural explanation. - Suspected heart failure, or a known weak heart muscle that needs periodic follow-up. - A previous heart attack, to see how much muscle was affected. - Suspected valve disease, including narrowing or leaking. The American Heart Association explains heart valve problems and disease. - Heart palpitations or an arrhythmia that may have a structural cause. - A congenital heart difference, or a family history of an inherited heart muscle condition. - Monitoring during chemotherapy that can affect the heart muscle. There are several forms of the test. A transthoracic echocardiogram is the standard scan through the chest wall. A stress echocardiogram compares images at rest and immediately after exercise. A transesophageal echocardiogram uses a probe passed into the esophagus. It gives a closer view when the standard scan is not detailed enough. How to prepare For a standard echocardiogram, preparation is minimal. - Eat and drink normally. No fasting is needed for a routine transthoracic study. - Take all of your medications as usual unless you are specifically told otherwise. - Wear a two piece outfit. You will undress from the waist up and wear a gown. A bra will need to be removed. - Skip lotion, oil, or powder on the chest that morning. These interfere with the gel and the probe. - Leave necklaces at home or plan to remove them. - Bring previous echocardiogram reports so changes over time can be compared. - Allow about an hour for the appointment. - A stress echocardiogram or a transesophageal study has different, stricter instructions, and they typically include fasting. Follow the specific directions you are given. What happens during the procedure You change into a gown and lie on an exam table. Usually you lie on your left side, with your left arm tucked under your head. That position brings the heart closer to the chest wall and improves the images. A wedge or pillow supports your back. Three small sticky electrodes are placed on your chest. They record your heart rhythm alongside the images. The room lights are dimmed so the sonographer can see the screen clearly. Warm water-based gel is applied to your chest. The probe is then moved across several positions, below the collarbone, between the ribs, under the breastbone, and sometimes at the base of the neck. Firm pressure is used at times to get past the ribs and lungs. That can feel uncomfortable, but it should not be painful. You will be asked to breathe in, breathe out, hold your breath briefly, or roll further onto your side. You will hear whooshing and pulsing sounds from the speakers. That is Doppler recording of blood flow, and it is expected. Sometimes the images are unclear. A contrast agent made of tiny gas-filled microbubbles may then be given through a small intravenous line to outline the heart chambers more sharply. When the study is finished, the gel is wiped off and the electrodes removed. Recovery and results There is no recovery. You dress and leave. You can drive, work, and exercise immediately. If contrast was used, the intravenous line is removed before you go. No special precautions are needed. The images are measured and interpreted by a physician. Reports usually reach Dr. Nanavati within a few days. He then reviews the results with you and explains them in context. A normal echocardiogram shows normal chamber sizes and normal wall thickness. The valves open and close cleanly, and the ejection fraction is normal, generally in the range of about 55 to 70 percent. The National Heart, Lung, and Blood Institute overview of heart tests explains what each measurement means. Abnormal findings guide the next step. A reduced ejection fraction leads to heart failure medication and close follow-up. A thickened wall or an abnormal valve may lead to repeat imaging at set intervals, a transesophageal study, or a referral. Wall motion abnormalities suggesting reduced blood supply may prompt advanced stress testing or coronary CT angiography. Risks and safety A standard echocardiogram is one of the safest tests in medicine. Diagnostic ultrasound has been used for decades with no evidence of tissue harm at the energy levels used. There is no ionizing radiation. The test can be repeated as often as needed, and it is safe during pregnancy. The discomforts are minor. The gel feels cool, and the probe pressure can be tender over the ribs. The electrode stickers may leave temporary redness or briefly pull the skin when removed. Ultrasound contrast, when used, is generally well tolerated. Allergic reactions are rare, and the agent clears from the body within minutes. Tell the team if you have had a reaction to it before or have a known right-to-left heart shunt. The main limitation is image quality rather than risk. Lung disease, obesity, chest wall shape, and previous chest surgery can make the heart harder to see. Sometimes the pictures are inadequate. Another approach such as a transesophageal echocardiogram or cardiac MRI may then be recommended.

Painless, no shocks, results read right away. What is an Electrocardiogram? An electrocardiogram, written ECG or EKG, is a quick painless test that records the electrical activity of your heart. Every heartbeat begins as an electrical signal in the sinoatrial node, the heart's natural pacemaker. From there it spreads through the muscle to make it contract. Ten small sticky electrodes placed on the chest, arms, and legs pick up those signals from the skin surface. A machine translates them into the familiar tracing of peaks and dips. It views the heart from twelve different angles. The pattern shows how fast the heart is beating and whether the rhythm is regular. It also shows whether the electrical signal is traveling normally, and whether any part of the heart muscle is thickened, strained, or short of blood. The recording itself takes about ten seconds, and the whole visit takes only a few minutes. No electricity is sent into your body. The machine only listens, so there is no possibility of a shock. Why Dr. Nanavati may recommend this The ECG is the first test in cardiology for good reason. It is fast, inexpensive, harmless, and it can identify an emergency within seconds. Dr. Nanavati may order an ECG if you have: - Chest pain, pressure, or tightness, where an ECG helps identify a heart attack quickly. - Heart palpitations, a racing pulse, or a skipped beat. - Dizziness, fainting, or near-fainting - Shortness of breath or unexplained fatigue. - High blood pressure, diabetes, high cholesterol, or a smoking history. - A known arrhythmia that needs periodic checking. - A new medication that can affect heart rhythm. - An upcoming surgery requiring cardiac clearance. - A pacemaker or defibrillator, as part of routine follow-up. The American Heart Association explains how arrhythmias are identified and treated, and the National Heart, Lung, and Blood Institute reviews the arrhythmias an ECG can reveal. How to prepare There is essentially nothing to do. That is part of why this test is so useful. - Eat and drink normally. No fasting is required. - Take all of your medications as usual, and bring an up-to-date list. Many medications change the tracing. - Avoid heavy exercise and caffeine right before the test if you can. Both raise heart rate. - Skip lotion, oil, and powder on your chest, arms, and legs that morning. Electrodes will not stick to slick skin. - Wear a two piece outfit. You will need to expose your chest. Your ankles and wrists must be reachable. - Leave off pantyhose and tight compression sleeves, since electrodes go directly on the skin. - Tell the staff if you have an allergy to adhesives, or if you have a pacemaker or defibrillator. - Bring copies of any previous ECG tracings. Comparison with an older tracing often matters more than the new one alone. - Allow about 10 to 15 minutes. What happens during the procedure You undress from the waist up and put on a gown. Then you lie flat on your back on an exam table. Your arms rest at your sides. The technician cleans small areas of skin and may lightly buff them with an abrasive pad. Excess chest hair is sometimes shaved in small patches so the electrodes make firm contact. Ten disposable electrodes are then applied. Six go across the chest in a precise pattern, and one goes on each arm and leg. The exact positions matter, because misplaced electrodes change the tracing. You are asked to lie still, relax your shoulders, breathe normally, and avoid talking. Muscle movement adds noise to the recording. A few seconds of stillness produces a much cleaner result. If you are shivering or tense, say so. The machine records for about ten seconds and prints a tracing. Sometimes a second recording is taken if the first is unclear or if an electrode came loose. The electrodes are then peeled off, which may sting slightly, and you can dress. Some people are asked to stay for a repeat tracing later. Others stay for continuous monitoring if a rhythm problem is suspected. Recovery and results There is no recovery. You can drive, work, and exercise immediately. Results are quick. The machine prints a computer-generated interpretation right away. That automatic reading is not the final word. A physician must review the tracing, because the software often over-calls or misses subtle findings. When an ECG is done in the office, Dr. Nanavati usually reviews it during the same visit and tells you what it shows. A normal ECG is reassuring but limited. It captures only ten seconds, so an intermittent rhythm problem can easily be missed. A normal tracing also does not exclude coronary artery disease. That is why symptoms that come and go often lead to Holter monitoring or a longer 7 to 10 day ambulatory rhythm monitor. An abnormal ECG points the way to the next test rather than settling the question by itself. Depending on the finding, that may be an echocardiogram for structure, a stress test for blood flow, or blood tests. Changes suggesting an active heart attack lead to emergency treatment immediately. Risks and safety A standard resting ECG has no medical risks. It is entirely passive. The electrodes read electrical signals that your heart already produces. No current passes from the machine into your body. There is no radiation, no needle, no dye, and no medication. The only real discomforts are minor. The electrode adhesive can cause brief redness or itching. A small number of people develop a mild rash that fades in a day or two. Removing electrodes from hairy skin can sting. Shaving small patches of chest hair leaves temporary stubble. Lying flat can be uncomfortable if you have back pain or trouble breathing when supine. The table can usually be raised slightly. The meaningful caution is interpretive. A single normal tracing does not rule out heart disease. A mildly abnormal tracing is often a harmless variant, particularly in young athletes. The tracing must be read alongside your symptoms, examination, and history. That is why it belongs in a cardiology visit rather than as an isolated result. If you have chest pain now, or pain with sweating, nausea, or breathlessness, call 911 rather than waiting for an office appointment.

Preparation, wearing it, and results. What is Holter Monitoring? A Holter monitor is a small portable recorder that captures every heartbeat for 24 to 48 hours. You wear it while you go about your ordinary day. It is essentially a continuous electrocardiogram. Several sticky electrodes go on your chest. Thin wires connect them to a recorder about the size of a deck of cards, which clips to your belt or hangs from a strap. Some newer versions are a single adhesive patch with no wires at all. The recording runs without interruption. That means it captures rhythm changes while you are working, climbing stairs, arguing, eating, or asleep. Those are moments a ten second office tracing will never see. You also keep a diary of symptoms and activities. Your cardiologist can then match what you felt to what your heart was doing at that exact minute. The test is painless, involves no radiation, and does not restrict most daily activity. Why Dr. Nanavati may recommend this A standard electrocardiogram is a snapshot. A Holter monitor is a full day of film. If your symptoms happen most days, a day or two of recording is usually enough to catch them. Dr. Nanavati may recommend Holter monitoring if you have: - Heart palpitations, fluttering, pounding, or a sense of skipped beats. - Dizziness, lightheadedness, or unexplained fainting. - Episodes of unexplained shortness of breath or chest discomfort. - A suspected slow heart rate, or pauses in the heartbeat. - Suspected atrial fibrillation, or known atrial fibrillation where the heart rate needs assessing. - A pacemaker or defibrillator whose function needs checking against symptoms. - A new rhythm medication that needs evaluation. - Follow-up after an ablation or other rhythm procedure. The American Heart Association explains atrial fibrillation and why the rhythm matters. The National Heart, Lung, and Blood Institute reviews the range of arrhythmias. If your symptoms occur only weekly or monthly, a longer 7 to 10 day ambulatory rhythm monitor is usually a better choice. How to prepare - Shower or bathe before your appointment. Most traditional recorders cannot get wet once the monitor is on, so this may be your last shower for a day or two. - Do not apply lotion, oil, powder, or body spray to your chest that morning. Adhesive will not hold on treated skin. - Wear a loose top that buttons or zips in front. Layers make the recorder easier to hide. - Men may need small patches of chest hair shaved for firm electrode contact. - Continue all of your medications unless told otherwise, and bring your list. The point is to record your heart as it usually behaves. - Tell the office about any adhesive allergy or sensitive skin. - Plan a normal day or two. Do not take time off and rest, because unusual quiet can hide the very problem we are looking for. - Bring a pen and paper, or plan to use your phone, for the symptom diary. - Allow about 20 to 30 minutes for the fitting appointment. What happens during the procedure There is no procedure in the surgical sense. Fitting the monitor is quick and painless. A member of the clinical team cleans several small areas of skin on your chest. They gently buff each spot to remove surface oil. Then they press the electrodes firmly into place and connect the lead wires. Finally they switch the recorder on and secure it at your waist or on a shoulder strap. We show you how to press the event button when you feel a symptom, and how to write the time and the symptom in your diary. That diary is the most valuable part of the test, so please complete it carefully. Note when you sleep, exercise, and feel anything unusual. Then you go home and live normally. Walk, work, cook, drive, and sleep as usual. Avoid soaking in a bath, swimming, or showering with a wired recorder. If an electrode peels up, press it back down rather than removing it. After 24 or 48 hours, you return the monitor to the office or follow the mailing instructions you were given. Recovery and results There is nothing to recover from. Once the electrodes are removed, your skin may look pink for a day. You can shower normally right away. Specialized software processes the recording first. A technician and a physician then review it. They compare the rhythm to the times noted in your diary. That takes several days to about two weeks. Dr. Nanavati then discusses the findings with you at a follow-up visit or by phone. A normal report is genuinely useful. It shows your heart rate range through the day and night. It also confirms that no dangerous rhythm occurred while you were symptomatic. Perhaps you felt palpitations during the recording and the rhythm was normal at that moment. That is strong reassurance. Other results guide the next step. Frequent extra beats may need only observation or a small medication change. Atrial fibrillation raises the question of stroke prevention and may prompt an echocardiogram. A slow rate with pauses may lead to a pacemaker discussion. If the recording is normal but symptoms continue, longer monitoring is the usual next move. Risks and safety Holter monitoring carries essentially no medical risk. The device only listens. It sends no current into your body, uses no radiation, and involves no dye, needles, or medication. The most common problem is skin irritation beneath the electrodes. Redness, itching, or a mild rash can occur, and it usually settles within a few days of removal. Tell the office if you have reacted to adhesives before, since we can use hypoallergenic electrodes instead. Practical annoyances are more likely than harm. The recorder is bulky under fitted clothing. Sleeping with wires takes some getting used to, and not showering for a day or two is inconvenient. Electrodes can also loosen with sweat. That is the usual reason a study has to be repeated. The main limitation is timing. Your symptoms may not occur during the recording window. The study can then look normal even though a real problem exists. That is a limitation of the test, not a clean bill of health. The monitor does not alert anyone in real time. Call 911 if you have severe chest pain, fainting, or serious trouble breathing while wearing it.

What is an IHD Evaluation? An IHD evaluation is the organized workup used to find out whether your heart muscle is getting enough blood. IHD stands for ischemic heart disease, which means the coronary arteries that feed the heart have narrowed, usually from plaque. Plaque is the fatty and calcified deposit that builds up inside artery walls. When a narrowed artery cannot deliver enough blood during exertion, the heart muscle becomes starved of oxygen. That is ischemia, and it often shows up as chest pressure, breathlessness, or unusual fatigue. The evaluation is a sequence rather than a single test. It starts with your history and examination, then adds blood work and an electrocardiogram. Imaging or stress testing then answers two questions. Is blood flow actually reduced, and if so, how much heart muscle is affected? The answers determine whether medication, lifestyle change, or a procedure is the right treatment. Dr. Vimal Nanavati coordinates the whole sequence for you. Why Dr. Nanavati may recommend this Ischemic heart disease is the most common form of heart disease, and it is often treatable long before a heart attack occurs. The National Heart, Lung, and Blood Institute describes coronary heart disease and its causes. The American Heart Association explains the warning signs of a heart attack. Dr. Nanavati may recommend an evaluation if you have: - Chest pain, pressure, tightness, or burning, especially when it comes on with exertion and eases with rest. - Discomfort spreading to the jaw, neck, shoulder, arm, or upper back. - Shortness of breath with activity, or a clear drop in stamina. - Nausea, sweating, or unusual fatigue with exertion, which are common presentations in women and in people with diabetes. - Several risk factors together, such as high blood pressure, high cholesterol, diabetes, smoking, or a strong family history. - An abnormal electrocardiogram or an incidental finding of coronary calcium on another scan. - A previous heart attack, stent, or bypass, where recurring symptoms need reassessment. Sudden severe chest pain is an emergency, especially with sweating, nausea, or breathlessness. Call 911 rather than booking an appointment. How to prepare The evaluation involves several tests, so preparation depends on which ones are scheduled. - Bring every medication and supplement you take, with doses, plus records of previous cardiac testing. - Write down your symptom pattern before the visit. What brings it on, how long it lasts, what relieves it, and whether it is changing. - Note your family history, particularly heart attack or sudden death in a parent or sibling before age 60. - For fasting blood work, expect 9 to 12 hours of water only if you are told to fast. - For stress testing, avoid caffeine for 12 to 24 hours. Wear walking shoes and comfortable clothing, and ask which medications to hold that morning. - For CT imaging, expect a period without food. Report any allergy to contrast dye and any kidney problems. - Ask whether you will need a driver, which is usually only the case if sedation is planned. - Allow extra time. Several appointments across a few weeks is normal. What happens during the procedure An IHD evaluation is a series of steps rather than one procedure. Not everyone needs all of them. It begins with a consultation. Dr. Nanavati takes a detailed history and examines you. He checks blood pressure in both arms, and listens to the heart, lungs, and major arteries. Blood tests follow. These typically include cholesterol and triglycerides, blood sugar or hemoglobin A1c, and kidney and liver function. Thyroid function and a blood count are usually checked as well. Advanced lipid testing may be added when risk is unclear. An electrocardiogram records the heart's electrical activity and can show evidence of a prior heart attack or ongoing strain. An echocardiogram shows chamber size, valve function, and pumping strength. It can also reveal areas of muscle that move poorly because of reduced blood supply. Functional testing comes next when needed. A treadmill or medication-based stress test shows whether blood flow falls short under demand. Imaging is sometimes added, such as advanced stress testing. Anatomic imaging such as coronary CT angiography pictures the arteries directly. If the findings suggest a severe blockage, a coronary angiogram in a hospital catheterization laboratory maps the arteries precisely. It also allows treatment during the same procedure. Recovery and results Most of the evaluation involves no recovery at all. You can drive, work, and exercise immediately after blood tests, an electrocardiogram, an echocardiogram, or a stress test. The exception is if you were sedated or told otherwise. Results arrive at different speeds. An electrocardiogram is read the same day. Routine blood work usually returns in a day or two, while advanced panels take longer. Imaging reports generally reach Dr. Nanavati within a few days. He then puts the pieces together and explains the overall picture rather than sending isolated numbers. The outcome falls into three broad paths. Testing may come back normal. The focus then shifts to prevention and to finding another explanation for your symptoms. Mild to moderate disease calls for medication, cholesterol and blood pressure control, and diabetes management. Smoking cessation and structured exercise matter just as much, and together these steps are highly effective. A severe blockage changes the conversation. The discussion turns to a procedure such as angioplasty or bypass surgery, followed by cardiac rehabilitation. Risks and safety The evaluation as a whole is low risk. Each step carries its own small and specific risks. Blood draws cause a brief sting and occasional bruising. Electrocardiography and echocardiography carry no risk at all, since both are passive tests and neither one uses radiation. Stress testing carries a small risk, because it deliberately makes the heart work harder. Chest discomfort, breathlessness, and fatigue are expected. Serious events such as a heart attack or a dangerous rhythm are rare. Testing is always supervised, with monitoring and emergency equipment on hand. Tests using contrast dye can cause allergic reactions, usually mild ones. The dye can also affect kidney function for a time. That matters most in people with kidney disease or diabetes. CT imaging and nuclear scans involve radiation exposure. We keep the dose as low as possible, and the information gained justifies it. Coronary angiography is the most invasive step. It carries small risks of bleeding at the access site and artery injury, and rarely heart attack or stroke. The guiding principle is simple. Each test should be ordered only when its result will change what happens next.

What is Left Atrial Appendage Closure? Left atrial appendage closure is a catheter-based procedure that seals off a small pouch attached to the left upper chamber of the heart. That pouch is the left atrial appendage, often shortened to LAA. It serves no essential function in adults, but atrial fibrillation changes that. In this irregular rhythm the upper chambers quiver rather than contract, so blood can pool inside the pouch and form a clot. A clot that escapes can travel to the brain and cause a stroke. Closing the pouch removes the most common site where these clots form. The procedure is done through a vein in the leg, so there is no chest incision. A small self-expanding implant is guided to the mouth of the appendage and released. Heart tissue then gradually grows over it. The goal is to lower stroke risk in people who cannot safely stay on long-term blood thinning medication. Why Dr. Nanavati may recommend this Atrial fibrillation substantially raises the risk of stroke, which is why blood thinning medication is the standard treatment. The American Heart Association explains atrial fibrillation and its link to stroke. The National Heart, Lung, and Blood Institute reviews how it is treated. Some people, however, cannot take anticoagulants safely. LAA closure exists for them. Dr. Nanavati may discuss this procedure if you have: - Atrial fibrillation not caused by a heart valve problem, with a stroke risk high enough to warrant treatment. - A history of serious bleeding on a blood thinner, such as gastrointestinal or brain bleeding. - A condition or occupation that makes bleeding especially dangerous, such as frequent falls. - Anemia or a bleeding disorder that makes long-term anticoagulation impractical. - A stroke or clot that occurred despite taking anticoagulation correctly. This is not a treatment for the arrhythmia itself. Your heart will still be in atrial fibrillation afterward. You may still need rate or rhythm medication. We perform the procedure at an affiliated hospital rather than in our office. The decision involves a careful weighing of your bleeding risk against your stroke risk. How to prepare - Expect imaging beforehand, usually a transesophageal echocardiogram or a CT scan. It measures the appendage and confirms no clot is already present. - Expect blood tests, an electrocardiogram, and a kidney function check. - Follow the specific instructions about your blood thinner. Some are continued and some are adjusted. Never decide this on your own. - Do not eat or drink after midnight, or as directed. Essential medications may be taken with a small sip of water. - Report allergies to contrast dye, iodine, latex, anesthesia, or any medication. - Arrange for an adult to drive you home, and plan for an overnight hospital stay. - Pack a small bag with your medication list, insurance information, and comfortable clothing. - Tell the team about sleep apnea, breathing problems, or previous difficulty with anesthesia. What happens during the procedure You lie on a table in a catheterization laboratory. Monitors track your heart rhythm, blood pressure, and oxygen. General anesthesia is commonly used, so most people are asleep and remember nothing. The team cleans, drapes, and numbs the skin over a vein in the groin. A sheath is placed into the vein. Thin catheters then travel up to the right side of the heart. Live X-ray images guide every step. Reaching the left atrium takes one more step. A small controlled puncture is made in the thin wall between the two upper chambers. This is a routine step in many heart procedures. The opening typically closes on its own over time. Ultrasound imaging from inside the esophagus or the heart shows the exact size and shape of the appendage. Contrast dye adds further detail. The implant is selected to match, then advanced in a collapsed state and positioned at the mouth of the pouch. Before it is released, the team tugs on it gently and re-images the appendage. This confirms the implant is stable, correctly sized, and sealing well. Only then is it detached. The catheters are removed, and pressure is applied at the groin. The procedure usually takes one to two hours. Recovery and results You wake in a recovery area and lie flat for several hours so the groin site can seal. Most people stay in the hospital overnight and go home the next day. Mild groin soreness and bruising are common for a few days. A sore throat from the breathing tube or ultrasound probe is also common. Avoid heavy lifting, straining, and strenuous activity for about a week, and keep the site clean and dry. Many people return to light activity and desk work within a few days. Blood thinning medication usually continues for a period after the implant is placed. That period is commonly around 45 days, while tissue grows over the device. Follow-up imaging is then done to confirm the appendage is sealed. If it is, the anticoagulant is often stopped. Antiplatelet medication such as aspirin takes its place, sometimes with a second agent for a while. Your exact medication plan depends on the imaging result and your bleeding history, and you must follow it precisely. You will need regular follow-up with your cardiologist afterward. Risks and safety This is a real heart procedure, and the risks deserve straightforward description. For most candidates the risk of a serious complication is low. It is not zero. One of the most significant risks is bleeding into the sac around the heart. This is called pericardial effusion, and it sometimes needs to be drained. Other risks include bleeding or injury at the groin access site. Stroke can occur during or shortly after the procedure. The device can also move out of position, which is rare but may require removal. A clot can occasionally form on the surface of the implant before tissue covers it. That is why the medication schedule and follow-up imaging matter so much. General anesthesia carries its own small risks. Contrast dye can affect kidney function or cause an allergic reaction. Tell any dentist or surgeon about the implant before procedures. Preventive antibiotics may be advised for a period. Call the office for fever, groin swelling, or new bleeding. Call 911 for chest pain, sudden weakness, difficulty speaking, or loss of vision.

What is an implantable loop recorder? An implantable loop recorder is a small heart monitor that sits just under the skin of the chest. The device is roughly the size of a small USB stick. It records the electrical activity of your heart continuously for up to three years. It has no wires and never touches the heart itself. Placement is a short outpatient procedure, done with numbing medicine through a tiny incision. Interrogation is the follow-up step. A wireless reader collects the stored recordings, and your cardiologist reviews what the device captured. A loop recorder listens for years rather than days. So it catches rhythm problems that a short-term monitor never sees, because they appear too rarely for a brief test to find. Doctors use it most often for unexplained fainting, infrequent palpitations, and stroke with no clear cause. The recorder does not treat your heart. It gathers evidence, so the right treatment can be chosen with confidence. Doctors also call the device an ILR, an insertable cardiac monitor, or simply a loop recorder. All of these names describe the same tool. Why Dr. Nanavati may recommend this A loop recorder is useful when symptoms are real but rare. Short-term testing works well for daily symptoms. An electrocardiogram captures only a few seconds of rhythm. Holter monitoring covers a day or two, and a 7 to 10 day ambulatory rhythm monitor covers a week or more. Your episodes may happen once a month or once a year. None of those tests is likely to be recording at the right moment. Dr. Nanavati may suggest a loop recorder when you have: - Fainting or near-fainting with no explanation after standard testing. - Heart palpitations that come and go unpredictably. - A stroke with no identified cause, where hidden atrial fibrillation is a possibility. - Suspected slow heart rhythms, pauses, or other arrhythmias. - A need to confirm whether rhythm control is holding after a prior treatment. Atrial fibrillation is a common irregular rhythm that raises stroke risk, and it often causes no symptoms at all. The National Heart, Lung, and Blood Institute explains why finding it matters even when a patient feels well. How to prepare Preparation is simple, and a few steps make the day easier. - Ask which medicines to hold. Blood thinners and anti-inflammatory drugs are the usual questions. Never stop a prescription on your own. - Expect a short fast. Most patients are asked not to eat or drink for about four to six hours beforehand. - Tell the team about allergies to latex, adhesives, antibiotics, or local anesthetic. - Shower the morning of the procedure, and skip lotion, powder, and perfume on your chest. - Wear a comfortable two-piece outfit with a loose top that opens in front. - Arrange a ride home, since you may receive mild sedation. - Allow two to three hours at the facility. The placement itself is brief. What happens during the procedure Placement usually takes about fifteen to twenty minutes. You stay awake and comfortable throughout. You lie flat on a procedure table, and a small intravenous line may be started. The skin over the left side of your upper chest is cleaned, then numbed with local anesthetic. You will feel a brief sting from the numbing medicine, and after that you feel pressure rather than pain. A tiny incision is made near the breastbone, often less than half an inch. The device is slipped into a small pocket just under the skin. There are no leads to thread into the heart, so nothing enters your bloodstream. The recorder is then switched on and programmed. Your team sets the heart rate limits that trigger automatic recording. The incision is closed with dissolvable stitches or surgical adhesive, and a small dressing covers it. Before you leave, staff show you how to use the patient assistant. Press it during a symptom. That tags the moment, so your cardiologist can look directly at it later. Recovery and results Most patients go home the same day. Keep the site clean and dry for the time your team specifies, usually about five to seven days. Mild soreness and bruising are normal for a week. Avoid heavy lifting and vigorous arm exercise for roughly two weeks, so the pocket heals well. Everyday walking and light activity are encouraged right away. Data reaches your care team in two ways. A bedside or smartphone transmitter sends recordings automatically, often overnight. You also come in for interrogation visits, where a wireless programmer reads the device in a few minutes. That visit is painless and needs no preparation. Results are reviewed alongside your symptom diary. A normal rhythm recorded during a fainting spell is genuinely useful information. It rules the heart out and points elsewhere. An abnormal rhythm may lead to medication, a pacemaker, or an anticoagulant to lower stroke risk. Dr. Nanavati will explain the findings in plain language, and he will outline the options at your follow-up visit. You can request an appointment online. Risks and safety Loop recorder placement is a low-risk minor procedure, and serious complications are uncommon. Possible problems include: - Bruising or a small collection of blood under the skin. - Soreness at the site for several days. - Skin irritation from the dressing or adhesive. - Infection, which is rare and may require removing the device. - The device shifting slightly under the skin. Call the office for spreading redness, drainage, fever, or worsening pain. Most current recorders are safe in an MRI scanner under specific conditions, so tell any imaging center that you have one. MedlinePlus offers a plain-language overview of the rhythm problems these monitors are designed to catch. The device does not shock you and does not pace your heart. Airport security, microwaves, and household electronics do not harm it.

Learn how to prepare, what the scan feels like, and how results are read. What is a nuclear stress test? A nuclear stress test shows how well blood reaches your heart muscle, both at rest and under stress. A very small amount of radioactive tracer is injected into a vein in your arm. The tracer travels in the blood and collects in heart muscle that is getting a good supply. A special camera then takes pictures of your heart. Two sets of images are recorded, one at rest and one after your heart has been made to work harder. That is done either by walking on a treadmill or by a medicine that mimics exercise. Comparing the two sets reveals areas that receive less blood when demand rises. That pattern points to a narrowed coronary artery. The test is also called myocardial perfusion imaging, or MPI. It does not open blockages. It tells your cardiologist whether a narrowing is actually limiting flow. It also shows how much heart muscle is affected. The cameras used are SPECT or PET scanners. Both are open at the sides, so the scan feels nothing like a closed MRI tube. Why Dr. Nanavati may recommend this The main reason is suspected coronary artery disease. That is a buildup of fatty plaque, and it narrows the arteries feeding the heart. Coronary artery disease remains the most common form of heart disease in the United States, according to the Centers for Disease Control and Prevention. Dr. Nanavati may order this study when: - You have chest pain, pressure, jaw or arm discomfort, or unusual shortness of breath. - A treadmill stress test was inconclusive, or your baseline ECG is hard to interpret. - You cannot exercise enough for a standard treadmill study. - Symptoms return after a stent or bypass surgery. - Your cardiologist needs to know whether a known narrowing is severe enough to treat. - Risk needs to be measured before major non-cardiac surgery. Imaging adds detail that an exercise test alone cannot provide. That is why it is often part of a broader ischemic heart disease evaluation. How to prepare Preparation matters here, because caffeine and some medicines can blunt the test. - Do not eat or drink for about four hours before the appointment, unless told otherwise. - Avoid all caffeine for at least twenty four hours. That includes coffee, tea, soda, energy drinks, chocolate, and decaf, which still contains a little. - Ask which heart medicines to hold. Beta blockers and some other drugs are commonly paused, but only on your doctor's instruction. - If you have diabetes, ask specifically about insulin and metformin dosing while fasting. - Tell the team if you are pregnant or breastfeeding, or if you have asthma or lung disease. - Wear a comfortable two-piece outfit and walking shoes. Leave lotions, powders, and oils off your chest. - Allow three to four hours. Much of that time is waiting between the injection and the pictures. What happens during the procedure An intravenous line is placed in your arm, and the first tracer dose is given. You then rest for roughly thirty to forty five minutes, so the tracer settles into the heart muscle. The first set of images is taken while you lie still with your arms above your head. Each scan takes about fifteen minutes. Next comes the stress portion. Electrodes on your chest monitor your rhythm, and your blood pressure is checked often. If you can exercise, you walk on a treadmill that gets gradually faster and steeper. If you cannot, a medicine is given through the IV instead. Regadenoson, adenosine, or dobutamine widens the arteries or raises the heart rate. That medicine can cause brief flushing, a headache, or a short feeling of breathlessness. These sensations fade within a few minutes. At peak stress the second tracer dose is injected. After another waiting period, the second set of images is taken. Staff monitor you throughout, and the test can be stopped at any point. Recovery and results There is no sedation, so most patients drive themselves home and return to normal activity the same day. Drink extra water through the day. The tracer leaves your body naturally in urine and stool, and its radioactivity fades quickly on its own. A cardiologist compares the rest and stress images. Your ECG tracing, your blood pressure response, and how long you exercised are all reviewed too. Reading the study carefully takes time, so results usually come back within a few business days rather than the same afternoon. A normal study is reassuring, and it often means medication and risk factor control are the right path. That may include advanced lipid testing to fine tune cholesterol treatment. An abnormal study may lead to coronary CT angiography or a catheter-based angiogram. Both look at the arteries directly. Risks and safety Nuclear stress testing is safe for the great majority of patients, and serious events are rare. The radiation dose is low, and it is comparable to other common medical imaging. Possible effects include: - Flushing, headache, or nausea from the stress medicine. - Brief chest discomfort or shortness of breath during stress. - Temporary irregular heartbeats. - A drop in blood pressure or lightheadedness. - Bruising at the IV site. - Very rarely, a heart attack or a serious rhythm disturbance. Staff trained in cardiac emergencies stay with you the whole time. Tell them right away about chest pain, dizziness, or severe breathlessness. The National Heart, Lung, and Blood Institute reviews how stress testing is used and monitored. Related services and conditions - Treadmill stress test when exercise alone is enough. - Advanced stress testing for more complex questions. - Echocardiogram to assess pumping strength and valves. - Coronary stenting if a significant blockage is confirmed. - Cardiac rehabilitation after a cardiac event or procedure. ## Pacemaker Interrogation URL: https://www.heartcare4life.com/services/pacemaker-interrogation Summary: A pacemaker interrogation is a painless wireless check of your device battery, leads, and stored rhythms. Learn what happens and how often it should be done. What is pacemaker interrogation? Pacemaker interrogation is a painless check of an implanted pacemaker. A handheld wand or wireless programmer is held over your chest, and it communicates directly with the device under your skin. Nothing is inserted, and no needles are used. The check reads three things. First, how much battery life remains. Second, whether the leads are still working properly. Leads are the thin wires connecting the device to your heart. Third, what rhythms the pacemaker has recorded since your last visit, including any fast or slow episodes you may not have felt. Your cardiologist can also adjust settings during the same visit, such as the lowest heart rate the device will allow. The appointment usually takes fifteen to thirty minutes, and you can drive yourself home afterward. Interrogation is how a pacemaker stays matched to your needs as your health changes over the years. Many modern devices also send data from home through a bedside or smartphone transmitter, which reduces the number of in-office visits needed. Why Dr. Nanavati may recommend this Every pacemaker needs regular checks. A pacemaker treats slow or unreliable heart rhythms by sending gentle electrical signals to the heart. The National Heart, Lung, and Blood Institute describes how these devices are monitored over their lifetime. Interrogation is done: - On a routine schedule, typically every three to twelve months depending on your device. - Shortly after implantation, to confirm the settings suit you. - When you have dizziness, fainting, fatigue, breathlessness, or heart palpitations. - If a lead or generator problem is suspected. - After a hospital stay, a heart procedure, or a change in your heart medicines. - Before and after certain scans or surgeries, including MRI. - As the battery approaches replacement, so the timing can be planned calmly. Stored recordings can also reveal silent atrial fibrillation, and that finding may change how stroke risk is managed. How to prepare There is very little to do, which is one of the advantages of this visit. - Eat, drink, and take your medicines normally unless your team says otherwise. - Bring your device identification card. It lists the manufacturer and model, which the programmer needs. - Bring an up-to-date medication list, including anything new started by another doctor. - Wear a two-piece outfit with a top that opens easily at the chest. - Write down any symptoms and the dates they occurred. Matching a symptom to a stored recording is often the most useful part of the visit. - Mention any recent falls, shocks, hospital visits, or planned imaging. - Allow about forty five minutes at the office, including check-in. What happens during the procedure You sit or lie down in an exam chair, and your shirt stays on in most cases. A programming wand is placed over the pacemaker site, or the device connects wirelessly instead. You will not feel the connection. The programmer downloads stored information. Your team reviews battery voltage and projected remaining life. Lead impedance and thresholds are checked next, along with the percentage of time the device has been pacing. Recorded rhythm strips are examined for pauses and fast atrial rhythms. Any arrhythmias that occurred between visits are reviewed too. Brief testing follows. The device may be told to pace slightly faster or slower for a few seconds, which confirms that the leads capture the heart reliably. Some patients feel a fluttering or a mild change in heartbeat during those seconds. It is not painful and it stops immediately. Settings may then be adjusted. Raising the lower rate limit, for example, can leave you less tired with activity. A summary is printed and stored in your chart. Sometimes an electrocardiogram is recorded alongside the interrogation for comparison. Recovery and results There is no recovery. You return to normal activity immediately, including driving and work. Most results are available during the visit itself. Dr. Nanavati will tell you the battery status in plain terms, usually as an estimate in years. He will also say whether the leads look stable. A battery nearing the end of its service means a generator change, scheduled well in advance. That short procedure replaces the device and keeps the existing leads in place when they are working well. Stored recordings may show a new rhythm problem. Next steps could include a medication change or further monitoring such as Holter monitoring. An echocardiogram can check how the heart is pumping. Your next interrogation date is set before you leave. Risks and safety Interrogation is one of the safest procedures in cardiology. Nothing enters the body, there is no radiation, and no sedation is needed. A few small points are worth knowing. During brief testing you may feel a few seconds of fluttering, skipped beats, or a faster pulse. Some patients feel a moment of lightheadedness while pacing settings are tested. These sensations end as soon as the test does. Very rarely, a device needs reprogramming during the visit because a setting is no longer suitable. That is exactly what the check is designed to catch. Between visits, keep your device card with you and avoid resting a mobile phone directly over the generator. Tell every clinician you see that you have a pacemaker.

Learn who needs it, how to prepare, what the procedure feels like, and what recovery involves. What is percutaneous transluminal coronary angioplasty? Percutaneous transluminal coronary angioplasty, or PTCA, is a catheter procedure that reopens a narrowed artery supplying the heart muscle. A thin flexible tube is passed into an artery at the wrist or groin, and X-ray pictures guide it to the heart. A very small balloon at the tip is positioned inside the narrowing, then inflated for a few seconds. The balloon presses the fatty plaque outward and widens the channel, so blood can flow again. In most cases a stent is placed in the same spot to hold the artery open. A stent is a tiny mesh tube. No chest incision is made, and you stay awake with numbing medicine and light sedation. PTCA is often called balloon angioplasty. Together with stenting it forms percutaneous coronary intervention, or PCI. It relieves angina, and during a heart attack it restores flow quickly to limit damage. Dr. Nanavati performs these interventional procedures at affiliated hospitals rather than in the office. Why Dr. Nanavati may recommend this PTCA treats coronary artery disease, the narrowing of heart arteries by plaque. The National Heart, Lung, and Blood Institute explains how this narrowing reduces oxygen delivery to heart muscle. It may be recommended when: - Chest pain or breathlessness continues despite medication. - Testing shows a significant blockage that is limiting blood flow. - You are having a heart attack, where opening the artery quickly is the priority. - Angina is limiting the activities you want to do. - A previously treated artery has narrowed again. Not every blockage needs a balloon. Stable symptoms are often treated first with medicines and risk factor control. Findings from a nuclear stress test or coronary CT angiography then show whether an intervention will genuinely help. Some patients are better served by bypass surgery, particularly when several arteries are involved. How to prepare - Expect to fast from midnight, or for at least six to eight hours, before a planned procedure. - Ask which medicines to hold and which to take with a sip of water. Blood thinners, diabetes drugs, and diuretics all need specific instructions. - Report allergies, especially to contrast dye, shellfish, or latex, and any prior reaction to imaging dye. - Tell your team about kidney problems. Contrast dye is filtered by the kidneys, so extra fluids may be given. - Bring a complete list of medicines and doses, including supplements. - Arrange a driver and someone to stay with you the first night at home. - Bring loose clothing, and plan for an overnight stay in case one is needed. Blood tests, an electrocardiogram, and sometimes a chest X-ray are done beforehand. What happens during the procedure You lie on a padded table in the cardiac catheterization laboratory. Monitoring pads and a blood pressure cuff go on, and an intravenous line delivers mild sedation. You stay awake but relaxed, and many patients remember little of it. Next the access site is numbed. That is either the wrist for a transradial angiogram or the groin for a transfemoral angiogram. A small sheath is placed in the artery. Catheters pass through the sheath without pain, because arteries have no sensory nerves inside. Contrast dye is then injected, so the arteries show up on the X-ray screen. The dye may bring a brief warm flush. The narrowing is then identified. A fine guidewire is passed across it, and the balloon is advanced over the wire. Inflation lasts only seconds. Flow is briefly interrupted, so you may feel pressure or short chest discomfort. Tell the team, because this is expected and manageable. A stent is usually deployed next, and final pictures confirm improved flow. Most procedures take thirty to ninety minutes. Recovery and results The sheath is removed, and the site is sealed with pressure, a band, or a closure device. Wrist access allows sitting up and walking sooner. Groin access requires lying flat for several hours to prevent bleeding. Many stable patients go home the next day. After a heart attack the stay is longer. Bruising at the access site is common, and it fades over one to two weeks. Avoid heavy lifting and strenuous activity for about a week. Follow your specific instructions on driving and returning to work. Dr. Nanavati can usually describe the result immediately after the procedure, often with images. Antiplatelet medication is essential after a stent, typically aspirin plus a second drug. Do not stop these without speaking to your cardiologist, because stopping early raises the risk of a clot forming in the stent. Cardiac rehabilitation is strongly encouraged, and it improves both fitness and long-term outcomes. Risks and safety PTCA is a well established procedure with a strong safety record, but it is still a heart procedure. Possible complications include: - Bleeding, bruising, or a lump at the access site. - Allergic reaction to contrast dye. - Kidney strain from the dye, more likely with existing kidney disease. - Clot formation or re-narrowing inside the treated artery over time. - Damage to the artery wall. - Irregular heart rhythms. - Rarely, heart attack, stroke, or the need for emergency bypass surgery. Risk depends on your age, your kidney function, and how many arteries are involved. It also depends on whether the procedure is urgent. The American Heart Association describes why rapid treatment matters most during a heart attack. Related services and conditions - Angioplasty, the broader term for balloon treatment of arteries. - Coronary stenting, usually performed at the same time. - Ischemic heart disease evaluation before deciding on treatment. - Advanced lipid testing to lower the risk of new blockages. - Coronary CT angiography, a non-invasive look at the arteries. ## Temporary Pacemaker URL: https://www.heartcare4life.com/services/temporary-pacemaker Summary: A temporary pacemaker steadies a dangerously slow heartbeat for hours or days. Learn why it is used, how it is placed, and what usually happens afterward. What is a temporary pacemaker? A temporary pacemaker is a short-term device that keeps the heart beating at a safe rate. Nothing is implanted under the skin, unlike a permanent pacemaker. A small generator, often called a pacing box, sits outside the body and connects to the heart through a thin wire. The wire is threaded through a vein in the neck, chest, or groin, then positioned inside the right side of the heart. The box sends gentle electrical pulses whenever your own heartbeat is too slow or pauses. Temporary pacing is used for hours to days. That is long enough to carry a patient through an emergency, a reaction to medication, or the period after heart surgery. It buys time. The underlying cause is treated or passes, and the wire is then removed. If the slow rhythm proves permanent, a permanent pacemaker is planned instead. Temporary pacing is always done in a hospital setting, where the heart rhythm is watched continuously. Why Dr. Nanavati may recommend this Temporary pacing is used when the heart's own electrical system becomes unreliable. It suits situations expected to be reversible or short lived. The National Heart, Lung, and Blood Institute describes the conduction problems that cause a dangerously slow heartbeat. Common reasons include: - Symptomatic bradycardia, a heart rate so slow it causes fainting, confusion, or low blood pressure. - Complete or advanced heart block, where signals fail to travel from the upper to the lower chambers. - Slow rhythms during or after a heart attack. - Slow rhythms caused by medication effects, high potassium, or infection while treatment takes effect. - Support during and after cardiac surgery, using wires placed on the heart at the time of the operation. - A bridge to a permanent pacemaker when one cannot be implanted immediately. Slow rhythms belong to the broader family of arrhythmias. An electrocardiogram is usually what identifies the problem first. How to prepare Temporary pacing is often urgent, so there may be little time to prepare. When there is time, the following applies. - You will be asked not to eat or drink beforehand. - Blood tests, including electrolytes and kidney function, are checked. - Tell the team about blood thinners and allergies to latex or local anesthetic. Mention any previous neck or groin procedures. - Bring or provide a complete medication list. Some heart medicines slow the pulse and may be paused. - Expect an intravenous line, oxygen monitoring, and continuous rhythm monitoring. - Consent is discussed with you or, in an emergency, with your family. - Plan for at least an overnight hospital stay, usually longer. What happens during the procedure Placement usually takes twenty to forty minutes. You remain awake with local anesthetic, and mild sedation is often given. The skin over a large vein is cleaned and numbed, most often in the neck or under the collarbone. A short sheath is placed into the vein. A pacing wire is then passed through the sheath and guided into the right ventricle, the lower right chamber of the heart. Live X-ray confirms the position, and sometimes ultrasound is used too. You should feel pressure but not sharp pain. The wire is then connected to the external pacing box. Your team tests how much energy reliably triggers a heartbeat, then sets the rate and output with a safety margin. You may briefly feel your heartbeat change during testing. The wire is secured with a stitch and covered with a sterile dressing. In an emergency, external pads on the chest can pace the heart through the skin for a short period. That method is uncomfortable, and it is used only until a wire can be placed. Recovery and results You stay on a monitored unit for as long as the pacing wire is in place. Movement is restricted so the wire does not shift, particularly if it enters through the groin. Nurses check the site, the connections, and the pacing thresholds regularly. The effect is immediate. A steady rate is restored, and blood pressure, alertness, and symptoms such as dizziness usually improve. Your team then works on the underlying cause, adjusting medicines or correcting electrolytes. Removal is quick and done at the bedside, and pressure is held over the site afterward. If your own rhythm returns and holds, no further device is needed. If it does not, a permanent pacemaker is scheduled. You then go home with that device, and regular pacemaker interrogation checks keep the settings right. The original episode may still be unexplained, and longer monitoring such as Holter monitoring may follow. Risks and safety Temporary pacing is generally safe and often lifesaving, but it is an invasive procedure. Possible complications include: - Bleeding or bruising where the vein was accessed. - Infection at the insertion site, which becomes more likely the longer the wire stays in. - The wire moving out of position, causing pacing to fail or become intermittent. - Irregular heartbeats triggered while the wire is being positioned. - Air entering the vein, or a collapsed lung when the chest veins are used. - Rarely, perforation of the heart wall. These risks are why temporary pacing is kept as brief as clinically possible. MedlinePlus provides general information on cardiac pacing devices.

Learn how to prepare, what sedation feels like, and what follows. What is transesophageal echocardiography? Transesophageal echocardiography, or TEE, is an ultrasound study of the heart taken from inside the esophagus. The esophagus is the swallowing tube that runs directly behind the heart. A slim flexible probe carries an ultrasound sensor on its tip. Your throat is numbed and sedation is given. The probe then passes through the mouth and into the esophagus. Only a thin wall separates the probe from the heart, so the pictures are far sharper than those taken through the chest wall. Ribs, lung tissue, and body habitus no longer get in the way. TEE is the preferred test when doctors need fine detail. Examples include looking for a blood clot in the upper chamber, checking an artificial valve, or searching for infection on a valve. It is a diagnostic study, not a treatment. It is also used to guide certain heart procedures in real time. The study is done with continuous monitoring of your heart rhythm, blood pressure, and oxygen level. Why Dr. Nanavati may recommend this A standard echocardiogram is taken through the chest wall, and it answers most questions. TEE is reserved for situations where a clearer view changes decisions. Common reasons include: - Looking for a blood clot in the left atrial appendage before restoring rhythm in atrial fibrillation. - Investigating a stroke of unknown cause, including a possible hole between the upper chambers. - Suspected infection on a heart valve, known as endocarditis. - Assessing a leaking or narrowed valve in detail, or checking a replacement valve. - Evaluating a heart murmur when chest wall images are not clear enough. - Guiding structural procedures such as left atrial appendage closure. - Suspected tear in the aorta, the body's main artery. The American Heart Association explains the valve conditions this test evaluates most often. How to prepare - Do not eat or drink for at least six hours before the test, and follow the exact fasting time you are given. An empty stomach is a safety requirement, not a formality. - Ask which morning medicines to take with a small sip of water. Diabetes medicines and blood thinners need specific instructions. - Tell the team about swallowing difficulty, hiatal hernia, or reflux. Also mention prior esophageal surgery, radiation to the chest, or any history of esophageal narrowing. - Report allergies to latex, anesthetic sprays, and sedatives, and any past reaction to sedation. - Remove dentures, partial plates, and oral piercings before the study. - Arrange a driver. You cannot drive for the rest of the day after sedation. - Allow about two to three hours in total, though the imaging itself is much shorter. What happens during the procedure An intravenous line is placed, and monitoring pads are attached. Your throat is numbed with a spray or gargle, which tastes bitter and makes the back of the mouth feel thick. Sedation is then given through the vein, so you feel drowsy and relaxed. Most patients remember very little afterward. You lie on your left side. A soft mouthpiece protects your teeth and the probe. You are asked to swallow once as the probe is passed. The probe is about the width of a finger, and it slides down the esophagus rather than the windpipe, so breathing is unaffected. A suction tip clears saliva. The cardiologist rotates and angles the probe to view the chambers, valves, and nearby vessels from several directions. Still images and video clips are recorded, and Doppler imaging measures the direction and speed of blood flow. Imaging usually takes fifteen to thirty minutes. The probe is then removed gently. Recovery and results You rest in a recovery area until the sedation wears off, usually about thirty to sixty minutes. Nurses check your breathing, blood pressure, and swallowing. Do not eat or drink until your throat numbness has fully worn off, generally at least an hour. Otherwise food or liquid can go down the wrong way. Start with cool water, then move to soft foods. A mild sore throat for a day is normal. Take the rest of the day off from driving, machinery, and important decisions. Preliminary findings are often shared before you leave. A full report is typically completed within a day or two, and Dr. Nanavati will then review the results and the plan with you. Next steps depend on what is found. They might include a medication change or further rhythm testing such as Holter monitoring. A referral for valve treatment or a scheduled structural procedure is also possible. Risks and safety TEE is a safe test in experienced hands, and serious complications are uncommon. The things to know are: - Sore throat or hoarseness for a day, which is the most common effect. - Nausea or gagging as the probe passes. - Temporary low blood pressure, slow breathing, or drowsiness from sedation. - Minor lip or tooth irritation from the mouthpiece. - Temporary irregular heartbeats. - Rarely, bleeding or injury to the esophagus, which is why swallowing history matters so much. Call the office promptly for chest or abdominal pain, difficulty swallowing, vomiting blood, or fever after the test.

Learn when this route is used, how to prepare, and what recovery needs. What is a transfemoral angiogram? A transfemoral angiogram is an X-ray study of your arteries, performed through the femoral artery in the groin. The skin is numbed first. A thin tube called a catheter is then placed into this large artery near the crease of the leg. The catheter is guided through the body to the heart, the legs, or whichever vessels need to be examined. Contrast dye is injected through it, and an X-ray camera records the flow. Narrowing, blockage, aneurysm, and abnormal connections all become visible on these images. You stay awake with light sedation. The study itself usually takes under an hour. The femoral artery is large, so it accommodates bigger catheters and more complex equipment than the wrist can. That makes this route the preferred choice for many advanced procedures. Treatment can often follow through the same access during the same visit. Doctors also call this femoral access. It is diagnostic imaging, and it guides what treatment follows. Why Dr. Nanavati may recommend this An angiogram is ordered when symptoms and non-invasive testing point toward significant arterial disease, but the details are still unclear. Reasons include: - Ongoing chest pain or breathlessness that suggests reduced blood flow to the heart. - Known or suspected coronary artery disease that may need treatment. - Leg pain with walking, non-healing wounds, or other signs of peripheral artery disease. - An abnormal stress test or vascular study. - Evaluation of an aortic aneurysm or other vessel abnormality. - Planning for a structural heart or vascular procedure that needs larger equipment. The National Heart, Lung, and Blood Institute describes how catheter-based artery studies are performed and used. Groin versus wrist access The alternative is a transradial angiogram through the wrist. Image quality is the same either way, and the tradeoffs are practical. The groin route uses a much larger artery. It accepts larger sheaths and bulkier devices, and it gives a straighter path to certain targets, including the leg arteries and the aorta. Complex and structural procedures often require it. It is also the fallback when arm vessels are too small, too twisted, or already used. Its drawback is recovery. The femoral artery is deep, so bleeding is harder to control. You must lie flat with the leg straight for several hours afterward. Bleeding and bruising complications are more common than with wrist access. A groin bleed can also be more serious, because it can track into the abdomen unseen. Many straightforward heart studies are therefore done through the wrist first. Dr. Nanavati weighs your anatomy, body weight, bleeding risk, kidney function, and the equipment required before choosing. How to prepare - Fast from midnight, or for at least six to eight hours, unless instructed otherwise. - Confirm which medicines to hold. Blood thinners, metformin, and diuretics each need specific direction. - Report allergies to contrast dye, iodine, shellfish, or latex, and any past reaction to imaging dye. - Tell the team about kidney disease. Dye is filtered by the kidneys, and extra fluids may be given. - Mention prior groin surgery, hernia repair, or vascular grafts in the leg. - Do not shave the groin yourself. Staff will clip hair if needed. - Arrange a driver and someone to stay with you the first night. - Allow most of the day, since lying flat afterward takes several hours. What happens during the procedure You lie flat on an X-ray table. Monitoring pads, a blood pressure cuff, and an oxygen sensor go on, and an intravenous line delivers mild sedation. The groin is cleaned and draped, then numbed with local anesthetic. You feel a sting, then steady pressure. A short sheath is placed into the femoral artery, often with ultrasound guidance to find the vessel precisely. Catheters pass through the sheath and travel to the target vessels. This part is painless, because the inside of an artery has no pain nerves. Contrast dye is then injected, and a warm flush through the body is normal and brief. The camera moves around you and takes pictures from several angles. You may be asked to hold your breath for a moment. A significant blockage may be found. Treatment such as angioplasty or coronary stenting can often be done immediately, avoiding a second procedure. Recovery and results At the end the sheath is removed, and firm pressure is held over the site. A closure device may be used to seal the artery instead. You then lie flat with that leg straight, typically two to six hours depending on the method used. Nurses check the site and the pulses in your foot regularly. Walking begins gradually once you are cleared to move. At home, avoid lifting, straining, stairs where possible, and vigorous activity for about a week. Keep the site clean and dry. Bruising is common and can look dramatic before it fades over one to two weeks. Call immediately for sudden swelling, a growing lump, or fresh bleeding. Severe groin or back pain also needs a call, and so does a cold, pale, or numb leg. Dr. Nanavati usually reviews the images with you the same day. The plan depends on the findings, and it may involve medication, stenting, surgery, or cardiac rehabilitation. Risks and safety Diagnostic angiography is low risk for most patients, though it is an invasive test. Possible complications include: - Bruising, bleeding, or a firm lump at the groin. - Pseudoaneurysm, a contained bulge where the artery was entered. - Arteriovenous fistula, an abnormal connection between the artery and a nearby vein. - Allergic reaction to contrast dye. - Kidney strain from dye, especially with existing kidney disease. - Blood clot or injury to the artery. - Rarely, heart attack, stroke, or serious bleeding. The American Heart Association provides background on artery disease outside the heart, which this study often evaluates. Related services and conditions - Transradial angiogram, the wrist access alternative. - PTCA for balloon treatment of a narrowed artery. - Ankle brachial index for non-invasive leg circulation screening. - Vascular ultrasound to assess arteries and veins without dye. - Ischemic heart disease evaluation. ## Transradial Angiogram URL: https://www.heartcare4life.com/services/transradial-angiogram Summary: A transradial angiogram examines your arteries through a small puncture in the wrist. Learn how it compares with groin access, how to prepare, and recovery. What is a transradial angiogram? A transradial angiogram is an X-ray study of your arteries, performed through the radial artery in the wrist. The skin is numbed first. A thin tube called a catheter is then placed into the artery just below the base of the thumb. The catheter is guided up the arm to the heart, or to whichever other vessels need study. Contrast dye is injected through it, and X-ray images capture the dye as it flows. Narrowing, blockage, and abnormal bulges show up clearly on those pictures. You stay awake with light sedation, and the whole study usually takes under an hour. The wrist route lets you sit up and walk soon after. The radial artery is shallow and near the surface, so pressure is easy to apply. Doctors often call this radial access. Treatment can frequently follow through the same catheter during the same visit. Angiography is a diagnostic tool. It shows the anatomy, so the right treatment can be planned. Why Dr. Nanavati may recommend this An angiogram is ordered when non-invasive testing has raised concern but has not settled the question. It remains the most detailed way to look inside the arteries. Reasons include: - Ongoing chest pain, pressure, or breathlessness suggesting reduced blood flow. - An abnormal stress test or imaging study. - Suspected or known coronary artery disease that may need treatment. - An ongoing heart attack, where the blocked artery must be found and reopened. - Return of symptoms after a previous stent or bypass. - Planning before valve or other cardiac surgery. The National Heart, Lung, and Blood Institute explains how catheter-based studies of the heart are used. Wrist versus groin access The alternative is a transfemoral angiogram through the groin. Both give the same picture quality, and the difference is the route. Wrist access has real advantages. Bleeding complications are less common, because the radial artery is small, close to the skin, and easy to compress. Most patients can sit up immediately and walk within a couple of hours. Many find that far more comfortable than lying flat, and recovery time in the hospital is often shorter. The wrist is not always the right choice. The radial artery is narrow and can go into spasm, which causes forearm discomfort. Some catheters and devices are too large for it. The groin usually serves other patients better. That includes people with very small arteries or prior radial procedures. It also includes anyone whose wrist artery may be needed later for dialysis access or bypass grafting. Very tortuous arm vessels can make the route difficult too. Your cardiologist decides based on your anatomy, the equipment needed, and the urgency of the situation, and may switch routes mid-procedure if necessary. How to prepare - Fast from midnight, or for at least six to eight hours, unless told otherwise. - Ask exactly which medicines to hold. Blood thinners, diabetes medicines including metformin, and diuretics all need direction. - Report any allergy to contrast dye, iodine, shellfish, or latex, and any past reaction to imaging dye. - Tell the team about kidney disease, since dye is cleared by the kidneys. - Mention any prior procedures on that wrist or arm, or a dialysis fistula on either side. - Arrange a driver and, ideally, someone to stay with you overnight. - Allow most of the day, even though the procedure itself is short. What happens during the procedure You lie flat on a table with your arm supported on a board. Monitoring pads, a blood pressure cuff, and an oxygen sensor are placed. An intravenous line delivers mild sedation, so you are relaxed but able to follow instructions. The wrist is cleaned and numbed. You feel a sting from the numbing medicine, then pressure. A small sheath goes into the radial artery, and medication is given through it to relax the vessel and prevent spasm. That can feel like a brief warm ache in the forearm. Catheters are advanced through the sheath toward the heart. Arteries have no internal pain nerves, so you will not feel this. Contrast dye is then injected, and the X-ray camera moves around you to take pictures from several angles. The dye often causes a warm flush. You may be asked to take a deep breath and hold it briefly. If a blockage needs treatment, angioplasty or coronary stenting can follow immediately. Recovery and results The sheath is removed at the end, and a compression band is placed around the wrist. The band is loosened in stages over one to three hours. Most patients sit up right away and walk when the band comes off. Keep the wrist still while the band is on, and tell staff about numbness, tingling, or increasing hand pain. At home, avoid lifting anything heavy with that arm for about two to three days, and keep the site clean and dry. Bruising is common and fades over a week or two. Call the office for swelling, bleeding, spreading redness, or a cold or pale hand. Dr. Nanavati can usually describe the images with you the same day. If arteries are clear, treatment focuses on medication and risk factors, which may include advanced lipid testing. If disease is found, options range from medical therapy to stenting to surgery. Cardiac rehabilitation is commonly recommended afterward. Risks and safety Diagnostic angiography is a low-risk procedure for most patients, but it is invasive. Possible complications include: - Bruising or bleeding at the wrist. - Radial artery spasm, causing temporary arm discomfort. - Radial artery occlusion, a blockage of the wrist artery that usually causes no symptoms because the hand has a second blood supply. - Allergic reaction to contrast dye. - Kidney strain from dye, particularly with existing kidney disease. - Irregular heartbeats. - Rarely, heart attack, stroke, or significant vessel injury. The American Heart Association explains why prompt evaluation matters when symptoms suggest a heart attack. Related services and conditions - Transfemoral angiogram, the groin access alternative. - PTCA, balloon treatment of a narrowed heart artery. - Nuclear stress test, often done before an angiogram. - Arterial ultrasound for non-invasive artery assessment. - Ischemic heart disease evaluation. ## Transthoracic Echocardiography URL: https://www.heartcare4life.com/services/transthoracic-echocardiography Summary: A transthoracic echocardiogram uses ultrasound through the chest wall to show your heart working. Learn what it shows, how to prepare, and how results arrive. What is transthoracic echocardiography? Transthoracic echocardiography, usually shortened to TTE, is an ultrasound scan of the heart taken through the chest wall. A small handheld probe called a transducer is pressed against the skin with a layer of gel. It sends harmless high-frequency sound waves into the chest, then listens for the echoes that bounce back from heart muscle, valves, and blood. A computer turns those echoes into moving pictures on a screen. The study shows the size and shape of each chamber, and how strongly the heart squeezes. It also shows whether valves open and close properly, and how blood moves through the heart. It involves no radiation, no needles, and no dye. Nothing is inserted into the body. Most scans take thirty to forty five minutes, and you lie on an exam table throughout. This is the standard echocardiogram. It is the most common heart imaging test performed. The scan can be done in the office, which makes it a practical first look when heart symptoms appear. Why Dr. Nanavati may recommend this An echocardiogram answers questions that a physical exam and an electrocardiogram cannot. It shows structure and pumping function rather than electrical activity. Common reasons include: - Shortness of breath, fatigue, swelling in the legs, or reduced exercise tolerance. - A heart murmur heard during an exam. - Chest pain that needs a broader heart evaluation. - Known or suspected valve disease, and periodic follow-up once it is diagnosed. - Assessment of the heart's pumping strength, reported as the ejection fraction. - Follow-up after a heart attack, or during treatment that can affect the heart, such as some chemotherapy. - High blood pressure that may have thickened the heart muscle. The National Heart, Lung, and Blood Institute describes the range of problems echocardiography can identify. How to prepare Preparation is minimal, which is one reason this test is used so often. - No fasting is needed for a standard study. Eat a light meal rather than a large one, since a full stomach can push against the diaphragm and blur images. - Take your usual medicines unless you are told otherwise. - Shower beforehand, and skip lotions, oils, powders, and body sprays on your chest. They interfere with gel contact. - Wear a two-piece outfit. You will undress from the waist up and wear a gown that opens at the front. - Bring a list of your medicines and any previous heart test results. - Allow about an hour at the office, including check-in and gowning. - Tell the technologist about recent chest surgery, breathing difficulty lying flat, or chest tenderness. What happens during the procedure You lie on an exam table, usually on your back first and then turned onto your left side. Turning to the left brings the heart closer to the chest wall and improves the pictures. Small electrodes are placed on your chest or limbs to track your heartbeat during the scan. Warm gel is applied to the chest. The technologist, called a sonographer, presses the transducer against the skin. The probe moves slowly between the ribs, below the breastbone, and at the base of the neck. Firm pressure is sometimes needed to get a clear window. That can feel uncomfortable but should not be painful. Say so if it is. You will hear whooshing and pulsing sounds. Those are Doppler recordings of blood flowing, and they are a normal part of the test. You may be asked to hold your breath briefly, to breathe out fully, or to stay still while a clip is recorded. The room is often dim, so the sonographer can see the screen clearly. Recovery and results There is no recovery period. The gel is wiped off, you dress, and you leave. Driving, eating, working, and exercise are all fine immediately. The sonographer records the images, but a cardiologist interprets them. Measurements are compared against normal ranges, and the moving clips are reviewed frame by frame. A written report is usually available within one to a few business days. Dr. Nanavati will explain the findings in practical terms. He will say how strongly the heart is pumping, and whether any valve needs watching. Many findings simply mean a repeat scan in a year. Others lead to further testing. Advanced stress testing follows if reduced blood flow is suspected, and a transesophageal echocardiogram gives a closer view of a valve or the upper chambers. Treatment may involve medication changes, blood pressure control, or referral for valve care. Risks and safety Transthoracic echocardiography is among the safest tests in medicine. Ultrasound at diagnostic levels has no known harmful effects, and the study can be repeated as often as needed. It is safe in pregnancy and safe for children. The only discomforts are minor. Pressure from the transducer can be tender, especially over the ribs or after chest surgery. The gel feels cool at first, though it is often warmed. Some patients find lying on the left side awkward. Electrode stickers occasionally irritate sensitive skin. One honest limitation is worth knowing. Image quality depends on your body's acoustic windows. Lung disease, obesity, chest deformity, or scarring can make pictures harder to obtain. A contrast agent may then be used to brighten the chamber borders, or a different test may be recommended.

Learn how to prepare, what to expect, and what the results mean. What is a treadmill stress test? A treadmill stress test records your heart while you walk, so your cardiologist can see how it responds to physical effort. Sticky electrodes on your chest connect to an electrocardiogram machine, which traces your heart's electrical activity continuously. A cuff checks your blood pressure every few minutes. You start walking slowly on a level treadmill, and every three minutes the belt speeds up and the incline rises. The goal is to reach a target heart rate for your age. You may instead reach the point where symptoms or fatigue stop you. Many heart problems stay hidden at rest and only appear when the heart has to work harder. This test brings them out. It also measures your exercise capacity and blood pressure response. It shows whether symptoms like chest tightness match what the tracing shows. It is also called an exercise stress test or a cardiac stress test. The whole appointment usually runs about an hour, with roughly ten to fifteen minutes on the treadmill. Why Dr. Nanavati may recommend this The main question is whether the heart gets enough blood during exertion. Reduced flow suggests coronary artery disease, the narrowing of heart arteries by plaque. The Centers for Disease Control and Prevention reports that heart disease remains the leading cause of death in the United States. Dr. Nanavati may order a treadmill test when: - You have chest pain, pressure, or unusual shortness of breath with activity. - Your risk factors warrant a closer look, such as diabetes, smoking, or a strong family history. - Symptoms such as palpitations or lightheadedness appear during exercise. - Your exercise capacity needs measuring before starting a program or returning to work. - A known heart condition is being followed over time. - Rhythm changes during exertion need to be documented. A resting electrocardiogram is normal in many people with narrowed arteries, which is exactly why exercise testing exists. How to prepare - Do not eat a heavy meal for about three to four hours beforehand. A light snack is usually acceptable, so confirm with the office. - Avoid caffeine and nicotine on the day of the test. - Ask which medicines to hold. Beta blockers slow the heart rate and can prevent you from reaching the target, but never stop one without instruction. - Wear loose clothing and, most importantly, proper walking shoes. Sandals and dress shoes make the test harder than it needs to be. - Skip lotions, oils, and powders on your chest, since electrodes will not stick to them. - Expect that a small area of chest hair may be clipped so the electrodes hold. - Bring your inhaler if you use one, and bring your medication list. - Allow about one hour at the office. What happens during the procedure You change into a gown that opens at the front. Ten electrodes are placed on your chest, and a blood pressure cuff goes on your arm. A resting tracing and a resting blood pressure are recorded first, standing and lying down. The treadmill starts slowly, at a pace most people describe as an easy stroll. Every three minutes it becomes faster and steeper. Staff talk with you throughout and ask how hard you feel you are working. Hold the handrails lightly for balance rather than leaning on them, since leaning reduces the workload and can affect results. The test stops when you reach your target heart rate, or when you feel you cannot continue. Staff will also stop it if they see a reason to. Fatigue and leg tiredness are the most common reasons, and stopping for those is normal, not a failure. Tell staff immediately about chest pain, severe breathlessness, dizziness, or leg pain. Afterward you slow to a cool-down walk, then sit or lie down. Monitoring continues for several minutes into recovery, because some meaningful changes appear only after exercise stops. Recovery and results There is no downtime. You can eat, drive, and return to normal activity right away, though many people feel pleasantly tired for a few hours. Your cardiologist reviews the ECG tracings at each stage. Your blood pressure response, how long you exercised, the heart rate you reached, and any symptoms you reported are all checked too. A report is usually ready within a few business days, and Dr. Nanavati will discuss it with you. A normal result is genuinely reassuring, and it often shifts the focus to prevention, cholesterol control, and exercise. An abnormal or unclear result usually leads to imaging, such as a nuclear stress test or another form of advanced stress testing, and sometimes to an angiogram. You may already have known heart disease. The results may then guide an exercise prescription through cardiac rehabilitation. Risks and safety Exercise testing is safe for the great majority of patients, and it is performed with trained staff and emergency equipment present. Serious complications are uncommon. Possible effects include: - Fatigue, leg heaviness, or breathlessness during and shortly after the test. - Chest discomfort, which is important information rather than a setback. - Dizziness or a drop in blood pressure. - Irregular heartbeats, usually brief. - Skin irritation from the electrode adhesive. - Very rarely, a heart attack or a serious rhythm problem. Tell the staff about anything you feel. Stopping early is always allowed. The National Heart, Lung, and Blood Institute explains how stress testing is supervised and what the results can show. Related services and conditions - Echocardiogram to assess structure and pumping function. - Ischemic heart disease evaluation for a full workup. - Holter monitoring when rhythm is the main question. - Coronary CT angiography for a non-invasive look at the arteries. - Arrhythmias that may appear with exertion. ## Vascular Ultrasound URL: https://www.heartcare4life.com/services/vascular-ultrasound Summary: Vascular ultrasound uses sound waves to check blood flow in your arteries and veins. Learn what it detects, how to prepare, and how the results guide care. What is a vascular ultrasound? Vascular ultrasound is the umbrella name for a family of painless scans. Vascular simply means relating to blood vessels. The name covers arteries, veins, and the grafts and stents placed inside them. Every study in the family works the same way. A handheld probe called a transducer is pressed against the skin over the vessel. It sends high-frequency sound waves into the body and records the echoes that return. A computer turns those echoes into a picture of the vessel wall. Doppler adds the direction and the speed of the blood inside. Combining the two is why these are called duplex scans. Three things change from one study to the next. The vessel examined, how you are positioned, and what the sonographer looks for. That is why your order names a specific study. This page explains what the whole family has in common. The pages linked below cover each scan in detail. These scans are available in our offices. That allows same-visit evaluation in many cases. Between them they find narrowing from plaque and blood clots. They also find leaking valves in veins, and weakened or bulging vessel walls. There is no radiation, no dye, no needles, and no sedation. Most studies take thirty to sixty minutes, depending on how many vessels are examined. Ultrasound is usually the first test ordered when circulation is in question, because it is safe and repeatable. Why Dr. Nanavati may recommend this The reasons depend on which vessels are involved. Arteries carry blood away from the heart, and veins carry it back. Common reasons include: - Leg pain or cramping that comes on with walking and eases with rest. - Leg swelling, aching, heaviness, skin discoloration, or a wound that will not heal. - Suspected blood clot in a deep vein, especially with sudden one-sided swelling. - Screening for narrowing in the neck arteries, evaluated with a carotid ultrasound and Doppler. - Reduced or absent pulses found during an exam. - Follow-up after a bypass, a stent, or another vascular procedure. - Watching a known aortic aneurysm over time. Peripheral artery disease is common. It is often silent in its early stages. The National Heart, Lung, and Blood Institute explains why. Depending on the question, Dr. Nanavati may order an arterial ultrasound, a venous ultrasound, or an ankle brachial index measurement alongside the scan. How to prepare Most vascular ultrasounds need no preparation at all. A few specific studies do. - For leg and neck studies, eat and drink normally and take your usual medicines. - For abdominal vessel studies, including the aorta, expect to fast for about eight hours. Gas and food in the bowel block the sound waves. - Wear loose, two-piece clothing. You may be asked to change into a gown for better access. - Leave jewelry and watches at home, or plan to remove them near the area being scanned. - Do not apply lotion, oil, or powder to the skin over the area being studied. - Bring your medication list and any prior vascular imaging reports. - Allow up to an hour, longer if both legs or several vessel groups are being studied. What happens during the procedure What every one of these scans shares is quick to describe. You lie on an exam table in a dimly lit room. Gel goes on the skin over the vessel. A probe glides across the gel. Images and flow readings are recorded, and the gel is wiped off at the end. Nothing is injected, and nothing is left behind. What changes between studies is everything that actually matters to you on the day. A carotid ultrasound is done lying flat with your head turned to one side. The neck has to be bare from the collarbone to the jaw. The probe stays light, and you may be asked not to swallow while a measurement is taken. An arterial ultrasound of a leg works down the limb in segments, from the groin to the ankle. Both legs are usually compared against each other. Abdominal arteries need firmer pressure and a held breath, so the sonographer can see past bowel gas. A venous ultrasound is the one where the probe presses down hard on purpose. A normal vein flattens shut under that pressure, while a vein holding a clot does not. The table is often tilted upright first, and part of a reflux study may be done standing. If your appointment letter does not name the vessel, call the office before you come in. Preparation is not the same across the family. An abdominal study needs fasting, and a leg study does not. Recovery and results No study in this family has a recovery period. You dress and leave. Nothing was given that has to wear off. Driving, eating, work, and exercise are all fine right away. The sonographer performs the scan, and a physician interprets it. Findings are compared with established measurements. One example is the speed of blood through a narrowed segment. That speed helps grade how significant the narrowing is. Reports are usually available within a few business days. Urgent findings are handled faster. A suspected deep vein clot is reported the same day so treatment can begin promptly. MedlinePlus describes why prompt treatment of a deep vein clot matters. Dr. Nanavati will explain what was found and what it means for you. Mild findings often lead to monitoring and risk factor treatment, including cholesterol and blood pressure control. Moderate findings may prompt repeat scanning at set intervals. Significant findings can lead to further imaging. They can also lead to a referral for treatment, such as venous ablation or an arterial procedure. Risks and safety Safety is the one place where these studies really are interchangeable. None of them uses radiation. None uses contrast dye. None involves a needle or sedation. The questions that come with a CT scan do not arise here. There is no allergy history to check, no kidney function to clear, and no dose to keep track of. That is why ultrasound is normally the first look at a circulation problem. It is also why a finding can be followed with repeat scans for years. Comfort varies more than safety does. Gel feels cool going on. Probe pressure is felt most in a leg that is already swollen or inflamed. The compression part of a vein study is where people notice it most. Lying still for up to an hour is the real complaint for people with back or hip pain. Tell the sonographer, because the table and the pillows can be adjusted. The shared limitation is simple. Sound has to reach the vessel in order to report on it. Anything in the way weakens the picture. Bowel gas, a cast, a dressing, or an open wound will all block the beam. So will heavy swelling and dense calcium in an artery wall. Depth matters too. A vessel far below the surface is harder to see clearly than one near the skin. Sometimes a scan cannot answer the question. The next step is then a test that does not rely on sound at all. That is most often CT or MR angiography. Moving on to it is a normal part of a workup, not a sign that anything went wrong.

Learn who benefits, how to prepare, what the day involves, and recovery timelines. What is venous ablation? Venous ablation is a minimally invasive treatment that closes a faulty vein in the leg. Healthy leg veins carry blood upward against gravity, and one-way valves stop it from falling back. Leaking valves let blood pool and pressure build, which produces bulging varicose veins, aching, swelling, and skin changes. Ablation seals the leaking vein, so blood reroutes through healthy veins nearby. A thin catheter is placed into the vein through a needle puncture, guided by ultrasound. Heat is delivered through the catheter tip, from either laser or radiofrequency energy. That heat makes the vein wall collapse and scar shut. The body gradually absorbs the closed vein. There is no vein stripping and no surgical incision, just a puncture that often needs no stitch. Most procedures take under an hour and use only local numbing medicine. You are able to walk out the same day. You may hear it called endovenous laser ablation, radiofrequency ablation, or endovenous thermal ablation. Why Dr. Nanavati may recommend this Ablation treats the underlying valve failure, not just the visible veins. Varicose veins are common, and the National Heart, Lung, and Blood Institute notes that they often reflect a problem with vein valves rather than a purely cosmetic issue. It may be recommended when you have: - Aching, throbbing, heaviness, or fatigue in the legs, especially late in the day. - Swelling around the ankle that worsens with standing. - Night cramps or restless, uncomfortable legs. - Itching, dry patches, or brown skin discoloration near the ankle. - Bleeding from a varicose vein, or a hardened tender vein from superficial clotting. - A venous leg ulcer, or skin that looks close to breaking down. - Symptoms that persist despite compression stockings, elevation, and exercise. A venous ultrasound is required first. It maps which veins leak and confirms that the deep veins are open, which is what makes closing a surface vein safe. This mapping is part of the vascular ultrasound testing done in our offices. Artery disease may also be suspected, and an ankle brachial index may then be checked first. Compression stockings are not appropriate when blood flow into the leg is poor. How to prepare - Have your mapping ultrasound completed, and bring the report if it was done elsewhere. - Most patients are asked to eat lightly rather than fast, since sedation is usually not needed. Confirm the instructions for your case. - Ask which medicines to hold, particularly blood thinners and anti-inflammatory drugs. - Report allergies to local anesthetic, latex, or adhesives. - Buy or bring your compression stockings ahead of time, since you will need them immediately afterward. - Shave the leg if instructed, and skip lotion or oil on the leg that day. - Wear loose trousers or shorts you can pull on comfortably over a dressing. - Arrange a ride if you expect to receive any sedation, and plan a walk afterward rather than a long drive. What happens during the procedure You lie on the procedure table with the leg exposed. Ultrasound traces the vein and marks the skin. The area is cleaned and draped. Local anesthetic numbs a small spot, usually near the knee or calf. A needle enters the vein, and a catheter is threaded up inside it under ultrasound guidance. You should feel nothing as it advances, since the inside of a vein has no pain nerves. The catheter tip is positioned a set distance below the groin crease, and its position is checked carefully. Next, dilute numbing fluid is injected along the length of the vein through several small needle sticks. This step is called tumescent anesthesia, and it does two jobs. It numbs the vein, and it pushes surrounding tissue and skin away from the heat. These injections are the part most patients notice, and they feel like brief stings and cold pressure. The energy is then delivered as the catheter is withdrawn slowly. You may feel warmth or a pulling sensation. The catheter is removed, pressure is applied, and a small adhesive dressing goes on. A compression stocking is fitted before you stand up, and you walk immediately. Recovery and results Walking is part of the treatment. Aim for ten to twenty minutes several times a day for the first two weeks, and avoid long periods of sitting or standing still. Keep the leg elevated when resting. Wear the compression stocking exactly as directed, commonly for one to two weeks. Expect some bruising and tightness, plus a pulling or cord-like feeling along the treated vein for two to three weeks. Over-the-counter pain relief is usually enough, and ice for ten minutes at a time helps. Most people return to desk work within a day or two. Avoid heavy lifting, running, and strenuous exercise for one to two weeks. A follow-up ultrasound is typically done within a week to confirm the vein has closed and to check the deep veins. Symptom relief such as reduced aching and swelling often begins within a few weeks. Cosmetic improvement takes longer, and some visible surface veins may still need additional treatment. Dr. Nanavati will review your results and any further steps at follow-up. You can request an appointment online. Risks and safety Venous ablation is a well established outpatient procedure with a good safety record, but no procedure is risk free. Possible complications include: - Bruising, tenderness, or a firm cord along the treated vein. - Temporary numbness or tingling from irritation of a nearby skin nerve. - Skin burn or discoloration over the treatment area, which is uncommon. - Superficial clotting in a nearby vein, causing a tender red streak. - Infection at the puncture site. - Deep vein thrombosis, a clot in a deeper vein, which is uncommon but important. - Recurrence of varicose veins over time, since the underlying tendency remains. Call the office for calf pain and swelling, worsening redness, fever, or sudden breathlessness. MedlinePlus offers a general overview of varicose veins and their treatment options.

Learn how to prepare and how the findings guide care. What is venous ultrasound? Venous ultrasound is a painless scan of the veins, most often in a leg or an arm. Veins are the return route. They carry blood back toward the heart, against gravity, helped along by one-way valves. Two things go wrong in that system. A clot can block the vein. Or the valves can leak and let blood fall backward. This scan is built to answer both questions. A handheld probe called a transducer is moved over the skin with gel. Sound waves go in, and the echoes come back as a picture of the vein wall and the blood inside it. Doppler adds the direction and the speed of flow. Because it pairs a picture with a flow reading, the study is often called a venous duplex scan. One feature sets it apart from an artery scan. The sonographer presses each vein closed on purpose, to see whether it collapses. There are no needles, no dye, and no radiation. Most studies take thirty to sixty minutes, and you can return to normal activity immediately afterward. Vein trouble causes swelling, aching, and skin changes, rather than the walking pain of artery disease. Arteries in the limbs are checked with an arterial ultrasound, and the neck arteries with a carotid ultrasound and Doppler. All three sit under the heading of vascular ultrasound. Why Dr. Nanavati may recommend this The most urgent reason is suspected deep vein thrombosis, a clot in a deep vein. A clot can break loose and travel to the lungs. That is why the testing is done quickly. MedlinePlus explains the warning signs and why prompt diagnosis matters. Other reasons include: - New swelling, pain, warmth, or redness in one leg or arm. - Leg heaviness, aching, or throbbing that worsens through the day. - Varicose veins, skin discoloration near the ankle, or a slow-healing ankle ulcer. - Mapping leaking valves before venous ablation or another vein treatment. - Follow-up after a previous clot or vein procedure. - Checking arm veins around an intravenous line or dialysis access. - Unexplained swelling where the cause is not clear. A dedicated reflux study is a version of this test done standing or sitting. Gravity is needed to reveal leaking valves. It is often combined with broader vascular ultrasound testing. How to prepare Almost no preparation is needed, which is one reason this test can be arranged quickly. - Eat and drink normally. Fasting is not required for leg or arm studies. - Take your usual medicines, including blood thinners, unless told otherwise. - Wear loose, two-piece clothing. You will likely change into shorts or a gown so the whole leg can be reached. - Remove jewelry and watches near the area being scanned. - Skip lotion, oil, and powder on the skin that day, since they interfere with the gel. - Remove compression stockings before the scan, and bring them to put back on afterward. - Tell the office about recent surgery, casts, wounds, or dressings on the limb. - Allow up to an hour, and longer if both legs are being examined. What happens during the procedure Two things make this exam different from an artery scan. The first is gravity. The second is squeezing. Gravity comes first. For a leg study, the head of the table is usually raised. Sitting your upper body up lets blood fill the leg veins the way it does when you stand. A vein that is properly full is far easier to judge. Parts of a reflux study go further and are done standing, because leaking valves only show themselves when blood is asked to travel uphill. Then comes the squeezing, and this is the heart of a clot study. The sonographer sets the probe crosswise over the vein and presses straight down. A normal vein has nothing solid inside it, so the walls meet and the vein vanishes from the screen. A vein holding a clot stays open under that same pressure. The probe then moves down a short distance and presses again. The step repeats from the groin, along the thigh, behind the knee, and into the calf. In a swollen leg this can feel tender. It should not be sharply painful, so speak up if it is. The Doppler part comes last, and it asks the valve question. You will hear flow through the speakers, rising and falling as you breathe. The sonographer may squeeze your calf. You may be asked to bear down as though straining, or to take a deep breath. Blood should surge toward the heart and then settle. Blood that slides back down the leg instead points to a valve that is not sealing. Both legs are often studied even when only one is bothering you. The normal side gives the sonographer something to compare against. Recovery and results Put your compression stockings back on if you wear them, and go. There are no activity limits at all afterward, and nothing needs to wear off. Results are read by a physician. When a clot is suspected, results are prioritized and reported the same day. Treatment with anticoagulation may need to start immediately. Routine reflux and follow-up studies are usually reported within a few business days. Dr. Nanavati will explain the findings clearly. A confirmed deep vein clot leads to blood thinning treatment. It also leads to a conversation about how long that treatment should continue. Leaking valves without a clot point toward chronic venous insufficiency. Management starts with compression stockings, leg elevation, walking, and weight control. When symptoms persist despite those measures, venous ablation may be considered. Sometimes the picture suggests artery disease rather than vein disease. In that case an arterial ultrasound or an ankle brachial index may be added. Risks and safety Nothing is injected, nothing is swallowed, and there is no radiation. So this study can be repeated as often as your care requires. That matters more here than on most pages, because vein problems are often tracked with repeat scans over weeks or months. Patients often ask whether pressing on a leg that may hold a clot is wise. The compression exam is the standard, long established way of looking for a clot, and vascular labs everywhere perform it the same way. The pressure is applied by hand, and it stops the moment you say it hurts. Most of the discomfort comes from that same pressing. A leg that is already swollen, warm, or inflamed is tender before the probe ever touches it. Warmed gel helps. So does telling the sonographer which spots are worst, so pressure there can be eased. Standing for a reflux study leaves a few people lightheaded, and there is always somewhere to sit down. The blind spots are worth stating plainly. Veins deep in the pelvis are hard to compress from the outside. The small veins in the calf can be hard to follow, especially through heavy swelling. Casts, dressings, and open wounds block the probe outright. When a segment cannot be cleared, the usual answer is a repeat scan in a few days to see whether anything has changed. A CT or MR venogram is the other option. The National Heart, Lung, and Blood Institute describes how venous clots are diagnosed and treated.

A heart attack is a potentially disastrous situation in a person's life, irrevocably changing his or her life forever. Indeed, a heart attack can take your life. This year 4 to 5 million people will be evaluated in US Emergency Rooms for chest pain. Of these, 2 million will be diagnosed with acute coronary syndrome (chest pain arising from active coronary disease). 1.5 million will experience an acute heart attack. Of the 1.5 million patients suffering an acute heart attack, one-half million will die, with 50% of these deaths occurring within the first hour. Including those who die before reaching the hospital, the first prolonged attack of pain has a 34% fatality rate and in 17% of patients, it is the first, last, and only symptom. Against these staggering odds, is there any way we can prevent this disastrous outcome? Identifying those factors in our life that directly increase the risk of a heart attack is the first step in avoiding this potential 911 call. Family History: A family history of heart disease can increase your risk of a heart attack. If close relatives have experienced cardiac conditions, especially at a younger age, it is important to discuss your family medical history with your doctor to better understand your personal risk. High Blood Pressure: High blood pressure places added strain on the heart and blood vessels, increasing the risk of heart attack over time. Monitoring your blood pressure regularly and managing it through lifestyle changes or medication can help protect your heart. Diabetes: Diabetes affects how the body processes sugar and can damage blood vessels that supply the heart. Poorly controlled blood sugar significantly raises heart attack risk, making proper diabetes management essential for long-term cardiovascular health. High Saturated Fat & Cholesterol Diet: A diet high in saturated fats and cholesterol can lead to plaque buildup in the arteries, restricting blood flow to the heart. Adopting heart-healthy eating habits can help reduce cholesterol levels and lower heart attack risk. Sedentary Lifestyle: A lack of physical activity can weaken the heart and contribute to weight gain and poor circulation. Regular exercise helps strengthen the heart, improve blood flow, and reduce the risk of heart attack. Smoking: Smoking damages blood vessels and reduces oxygen levels in the blood, increasing the likelihood of heart attack. Quitting smoking can rapidly improve heart health and significantly lower cardiovascular risk. Narcotic Drugs: The use of narcotic or illicit drugs can place extreme stress on the heart and disrupt normal rhythms. Avoiding drug use and seeking medical support when needed can greatly reduce the risk of sudden cardiac events. Are you Having a Heart Attack? - Are you having chest tightness? - Chest heaviness? - Shortness of breath? - Arm, jaw or neck pain or tightness? - Indigestion - Palpitations - Light Headness - Feeling like you’re going to pass out? If you are having one or any of these symptoms, you may be having a heart attack. DO NOT WAIT ANOTHER MINUTE. Have it checked out by a Doctor. Call 911 and let the Paramedics do the work. Don’t drive yourself to the Emergency Department. By being always vigilant for these symptoms and getting medical attention promptly, you may be able to avoid a heart attack. ## Tell a Friend URL: https://www.heartcare4life.com/tell-a-friend Summary: Know someone who needs a cardiologist?

Fields marked () are required ## Treatments URL: https://www.heartcare4life.com/treatments Summary: What an echocardiogram, ECG, Holter monitor, stress test and venous ultrasound involve, explained before your test at our Bonita or Redding cardiology office. - ## Echocardiogram An echocardiogram or echo is a type of ultrasound scan that noninvasively assesses the heart’s structure and function. This is done by using a small probe or transducer which sends out high-frequency sound waves that create echoes when they bounce off different parts of the heart. These echoes are picked up by the probe and turned into a moving image on a monitor. Know More - ## Electrocardiogram (ECG / EKG) Electrocardiogram (ECG or EKG) is a medical test that measures and records the electrical activity of the heart. The heart is a muscular organ that beats rhythmically to pump blood throughout the body delivering oxygen to organs and tissues. The sinoatrial node, SA node, is the natural pacemaker of the heart. It sends signals to the muscle fibers of the heart telling them when to contract. Each contraction is one heartbeat. Know More - ## Holter Monitoring A Holter monitoring study, also known as 24-hour ambulatory ECG, is a painless, portable diagnostic test that measures your heart’s activity for 24 to 48 hours while you perform your daily normal routine. Know More - ## Advanced Stress Testing Advanced cardiac stress testing is a non-invasive diagnostic procedure that utilizes Positron Emission Tomography/Computerized Axial Tomography (PET/CT) to provide detailed images of the coronary arteries, at rest as well as under stress (increased blood flow induced by a medication). It determines the ability of the heart to respond to stress and evaluates the adequacy of blood supply to the heart. Know More - ## Advanced Lipid Testing Standard lipid tests may demonstrate a normal LDL and total cholesterol level in patients with a risk of atherosclerotic disease. Moreover, patients with a significant reduction in LDL cholesterol following lipid-lowering therapy may still develop coronary heart disease. Thus standard lipid testing which measures total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides is not sufficient to predict the overall risk for heart attack and strokes. Know More - ## Left Atrial Appendage Closure It is a small ear-like pouch in the wall of the left atrium of the heart. It forms during the fourth week of embryonic development. The function of the LAA is unknown. Know More - ## Venous Ultrasound Venous ultrasound imaging, also known as venous duplex or Doppler ultrasound, is a medical imaging technique that uses high-frequency sound waves to create images of the veins in the body, primarily the extremities (legs and arms). This non-invasive procedure helps healthcare professionals assess the blood flow in veins and detect abnormalities such as blood clots, venous insufficiency, or other vascular conditions. Know More - ## Carotid Ultrasound/Doppler A carotid doppler is an ultrasound imaging technique used to determine the presence of possible blockages in the carotid arteries that run on either side of the neck and carry blood to the brain. A carotid Doppler helps visualize the carotid arteries and the blood flowing through them. Know More - ## Arterial Ultrasound Arterial Doppler ultrasound is a non-invasive imaging test used to visualize the blood flow in the arteries, by bouncing high frequency sound waves(ultrasound) over the circulating blood cells. Know More - ## Angioplasty Arteries, blood vessels that carry oxygen-rich blood to all the parts of the body, are normally flexible and smooth on the inner side, but deposits of cholesterol, calcium, and fibrous tissue (plaque) can build up on the inner walls of the arteries, making them hard, stiff and narrow. This process of thickening and hardening of the arteries is called atherosclerosis. Know More - ## Loop Recorder Implantation and Interrogation Loop recorder placement or implantation is a minor surgical procedure to place a type of heart recording or monitoring device called an implantable loop recorder (ILR) underneath the skin of your chest, overlying the heart. The device functions as an electrocardiogram (ECG), continuously recording electrical activity from your heart for up to 3 years. Know More - ## Treadmill Stress Test The treadmill stress test, also known as an exercise stress test or cardiac stress test, is a diagnostic test that helps determine how well your heart can handle increased physical activity. This test monitors blood pressure, heart rate, and the flow of blood through the different heart chambers. Know More - ## Nuclear Stress Test A nuclear stress test is an imaging technique to evaluate how well blood flows into the heart muscle, both during activity and at rest. The test involves the administration of a small amount of radioactive material, such as thallium or sestamibi, into the bloodstream through a vein and capturing your heart images using a positron emission technology (PET) scanner or single photo emission computed tomography (SPECT) scanner. Know More - ## Ankle Brachial Index (ABI) The ankle-brachial index (ABI) is a non-invasive diagnostic test performed to determine your risk of peripheral artery disease (PAD), a condition of narrowing or blocking of the arteries in your legs or arms. This condition increases the risk of stroke, leads to poor blood circulation, and may cause heart attack and leg pain. The ankle-brachial index is determined by comparing the blood pressures of the ankle and the arm Know More - ## Coronary CT Angiography Coronary computed tomography (CT) angiography or heart CT scan is a non-invasive diagnostic technique that uses contrast material to detect any abnormalities within the coronary arteries. Know More - ## Transfemoral Angiogram Transfemoral angiogram is performed under local anesthesia. It takes about an hour to complete and is an outpatient procedure. Your surgeon makes an incision in your groin and inserts a catheter into the femoral artery, which is guided through the artery with the help of X-ray imaging. Know More - ## Transradial Angiogram Transradial angiogram is performed under local anesthesia. It takes about an hour to complete and is an outpatient procedure. Your surgeon makes an incision over your wrist and inserts a catheter into the radial artery, which is guided through the artery with the help of X-ray imaging. Know More - ## Transesophageal Echocardiography Transesophageal Echocardiography (TEE) uses high-frequency sound waves (ultrasound) to generate high-quality dynamic images of the heart and its blood vessels. TEE employs an ultrasound transducer to produce sound waves and is positioned on an endoscope (long, thin, flexible instrument) that is guided down the throat into your esophagus. Know More - ## Transthoracic Echocardiography Transthoracic echocardiography (TTE) is a noninvasive imaging modality that uses high-frequency sound waves (ultrasound), to examine and obtain images of the heart. A small instrument called a transducer is placed on different locations of the chest wall. The transducer sends ultrasound waves to the deeper internal structures and picks up the echo signals. The computer attached to the echo machine converts them into images that are projected on a monitor. Know More - ## IHD Evaluation Ischemic heart disease (IHD) is a condition characterized by reduced blood supply to the heart. The decrease in blood supply is caused due to the deposition of plaque (waxy substance) along the walls of the artery that supply blood to the heart muscles (coronary artery), leading to narrowing or blockages in the artery. The management of IHD and its symptoms are essential to reduce the risk of heart attack. Know More - ## Temporary Pacemaker The heart is a muscular organ that pumps blood throughout the body. The rhythmic beating of the heart is triggered by electrical signals. A change or interruption in these signals can cause a change in the rhythm of the heart. A pacemaker is a device that stabilizes the heart rhythm. Know More - ## Cardiology Services Cardiology is a branch of medicine that deals with the study, diagnosis, and treatment of disorders related to the heart and the blood vessels – the cardiovascular system. A medical doctor who specializes in cardiology is known as a cardiologist. Know More - ## Cardiac Rehabilitation Cardiac rehabilitation is an active program that facilitates cardiac patients to recover from a heart attack and other forms of disability due to heart ailments or surgeries. Know More - ## Vascular Ultrasound A vascular ultrasound is a non-invasive imaging test used to evaluate blood flow through arteries and veins. It uses high-frequency sound waves to create real-time images of blood vessels and detect abnormalities such as blockages, narrowing, blood clots, or weakened vessel walls.

Because of his vast knowledge and caring attitude, he far supercedes them.. He doesn't make you feel rushed and explains everything in plain talk so you can understand what's going on with your heart. When you' re somewhat fearful because your body needs some serious help; you don't need to have a 'newbie' caring for you! Experience matters.. I strongly encourage anyone who wants to have a 'different' experience with a doctor to make an appointment with him right away! He's definitely someone you want on your team from the get go! The office staff is also a reflection of him - thoughtful and very caring! Calls are answered or returned very quickly if you need anything! You won't be disappointed... - 5/5 (Healthgrades) Very caring and comfortable doctor.i prayed and asked for good doctor I believe prayer was answered. - 5/5 (Healthgrades) Wonderful Experience Dr. Nanavati provided a very professional and comfortable first experience for both my husband and myself. We both felt confident that he is very competent and thorough in his diagnosis and follow up. He was attentive, answered all of our questions, was respectful and pleasant. I can't say enough positive things about our experience. We would highly recommend him based on our experiences. - 5/5 (Healthgrades) A A: The best cardiologist My first appointment with Dr Nanavati was one of the best interactions with a cardiologist during last several years. He was found to be a very knowledgable, caring, friendly physician who pays attention to all of your concerns, listens to you with patience and answers all of your questions. I have been a patient at this center in Redding and am really happy to have Dr Nanavati here to be my cardiologist. - 5/5 (Healthgrades) M T: I would definitely recommend Dr. Nanavati.

I have been very satisfied with his care over the last 3 years. He is very good at listening to his patients. I don't feel like I'm being rushed while I'm at an office visit. He usually reacts rather quickly when I explain a problem I'm having regarding prescriptions or other medical care issues. In other words, Dr. Nanavati does whatever, is needed when I have a question or problem. - 5/5 (Zocdoc) G D: A pleasant experience! - 5/5 (Zocdoc) R J: The doctor was very good as well as informative. - 5/5 (Zocdoc) E A: Me deio mucha confiasa! - 5/5 (Website) My original interaction with Dr. Nanavati came in 2001, when I had begun experiencing chest pains. I was the Vice President of Instruction & Student Affairs/Deputy Superintendent at Shasta College in Redding, California. Because the work was extremely stressful, I figured the pains were from the job itself. When they lingered, I asked the Nursing faculty to recommend a cardiologist. To the person, each one said that I should go to Dr. Nanavati. At my first appointment with him, he diagnosed me with a blocked artery and said I would need heart bypass surgery, which I did. Throughout my recovery and to this day, Dr. Nanavati has been my cardiologist. My wife and I moved to Southern California in 2004, and he relocated to the San Diego area. Even given a three-hour drive from where we currently live to his office, he is the only cardiologist I go to for everything from routine checkups to surgeries and procedures. Primary among why Dr. Nanavati has been my cardiologist of choice since 2001 is that he is the consummate professional. He maintains and continuously expands his knowledge and skills to keep up with the most current cardiological advancements, all to the benefit of his patients. He readily and willingly explains my heart issues to me in terms that leave me no doubt regarding his recommendations for my care. Additionally, his personable and professional style gives me complete confidence that he genuinely cares for me as his patient. He is direct in discussing the care he recommends and equally forthright in ensuring that I know all the options and risks so that together we can make the best choices for my heart health. In addition to my heart bypass, I have had a stent implanted, a pacemaker, a Barostim device, and many heart-related tests. In all instances, Dr. Nanavati has been the cardiologist in whom I have placed my trust and confidence. His knowledge and skills are surpassed only by how much he genuinely cares for and about me as his patient. I know this to be true regarding others of his patients because they have shared with me their deep admiration for him. That I am in the strong heart health I currently enjoy is due exclusively to the care I have received from Dr. Nanavati. I enthusiastically recommend him to anyone who is looking for a first-rate doctor, and I do so without any hesitation whatsoever. Website-reviews - 5/5 (Website) Bruce N: Several years ago I was hospitalized for a catherization procedure. After the procedure I was contacted by my cardiologist who advised me I had severe blockage, and nothing could be done. Needless to say my family and I were devastated. We decided to get a second opinion, and contacted Dr Nanavati at his office by phone. The office was closed as it was after business hours,but Dr Nanavati answered the phone. Dr Nanavati responded to the hospital, met my family, pulled a chair up to my bed, and when told of my results of my catherization, and cardiologist opinion, stated “ that’s not true there is something we can do.” Dr Nanavati spent 30 minutes with me and my family, explaining about medications that could improve my condition. He also contacted San Francisco University to set me up for a heart transplant if necessary, after several visits to San Francisco my condition had improved so much due to the medications Dr Nanavati prescribed I no longer qualified for the transplant. Since that time I have been under Dr Nanavati’s care with positive results. Dr Nanavati is a well qualified, caring,assessable cardiologist. His most important asset is he will listen to his patients. Website-reviews - 5/5 (Website) Harry and Ellen: Dear Dr Nanavati Just wanted to thank you for the check up on the spur of the moment. I know that it was an extra effort and it was greatly appreciated. We traveled to Redding in good weather there and Back . Roads were in god shape all the way. If you and your wife come over to Arcata I want to extend an invitation to go to dinner with us, at the restaurant in Eureka, that serves dishes from India. You might just enjoy it. I saw Dr Lindsey yesterday and she will work with me on this B.P problem. My patient is going to start day care 4 days a week and I’ll get myself into Volunteer work soon Thanks again for your help.

I saw Dr. Vimal Nanavati after being with two other Cardiologist Groups in Shasta county. Because of his vast knowledge and caring attitude, he far supercedes them.. He doesn't make you feel rushed and explains everything in plain talk so you can understand what's going on with your heart. When you' re somewhat fearful because your body needs some serious help; you don't need to have a 'newbie' caring for you! Experience matters.. I strongly encourage anyone who wants to have a 'different' experience with a doctor to make an appointment with him right away! He's definitely someone you want on your team from the get go! The office staff is also a reflection of him - thoughtful and very caring! Calls are answered or returned very quickly if you need anything! You won't be disappointed... - 5/5 (Website) Very caring and comfortable doctor.i prayed and asked for good doctor I believe prayer was answered. - 5/5 (Website) Wonderful Experience Dr. Nanavati provided a very professional and comfortable first experience for both my husband and myself.

We would highly recommend him based on our experiences. - 5/5 (Website) A A: The best cardiologist My first appointment with Dr Nanavati was one of the best interactions with a cardiologist during last several years.

I have been a patient at this center in Redding and am really happy to have Dr Nanavati here to be my cardiologist. - 5/5 (Website) M T: I would definitely recommend Dr. Nanavati.

He is also very caring, extending himself to make sure his patients understand what is doing and why they need to take that procedures he has recommended. I recommend him above any other cardiologist I know of. - 5/5 (Website) R E: The doctor has been my cardiologist since I arrived in Chula Vista. I have been very satisfied with his care over the last 3 years. He is very good at listening to his patients. I don't feel like I'm being rushed while I'm at an office visit. He usually reacts rather quickly when I explain a problem I'm having regarding prescriptions or other medical care issues. In other words, Dr. Nanavati does whatever, is needed when I have a question or problem. - 5/5 (Website) G D: A pleasant experience! - 5/5 (Website) R J: The doctor was very good as well as informative. - 5/5 (Website) E A: Me deio mucha confiasa!
