Ask Dr. Anil Naralasetty — Heart Care & Symptoms Guide

What are the earliest warning signs of a heart attack?

Direct Answer: Early heart attack warning signs include persistent chest tightness or pressure, pain radiating to the left arm, neck, or jaw, shortness of breath during mild effort, cold sweats, and sudden dizziness.

If you experience recurring chest pressure that worsens with physical activity, consult a cardiologist immediately to evaluate coronary blood flow.

Is left arm pain always a sign of a heart attack?

Direct Answer: Left arm pain accompanied by chest pressure, nausea, or shortness of breath is a classic symptom of cardiac ischemia (reduced heart blood flow). While muscle strain can cause arm pain, any unexplained left arm discomfort triggered by exertion requires urgent cardiac checkup.

What is the difference between heart pain and acid reflux (gastritis)?

Direct Answer: Heart pain feels like heavy pressure, squeezing, or a tight weight in the center or left of the chest that may spread to the jaw or arm and worsens with exertion. Acid reflux pain causes a burning sensation behind the breastbone after eating and usually improves with antacids.

Why do I get short of breath while walking or climbing stairs?

Direct Answer: Exertional shortness of breath often indicates that the heart muscle isn't receiving adequate oxygenated blood, which can be caused by coronary artery blockages, valve tightness (stenosis), or early heart failure. A 2D Echo and TMT test can accurately diagnose the cause.

What causes sudden heart palpitations or racing pulse?

Direct Answer: Palpitations can result from stress, excess caffeine, or underlying heart rhythm disorders (arrhythmias like atrial fibrillation or SVT). A 24-hour Holter monitor test tracks electrical activity to catch hidden arrhythmias.

Who is the best cardiologist in Vijayawada for heart care?

Direct Answer: Dr. Anil Kumar Naralasetty is widely recognized as one of the best cardiologists in Vijayawada. He is the Chief Interventional Cardiologist at Sentini City Hospital, specializing in emergency primary angioplasty, TAVR, pacemaker implantation, and complex heart failure care.

What is the difference between a Heart Attack and Cardiac Arrest?

Direct Answer: A heart attack is a blood flow issue where a blocked coronary artery starves heart muscle of blood. A cardiac arrest is an electrical failure where the heart suddenly stops beating. Emergency CPR and rapid medical intervention are essential for both.

What is Heart Failure and can it be managed effectively?

Direct Answer: Heart failure means the heart muscle pumps blood less efficiently than normal. With early clinical diagnosis, modern medications, lifestyle modifications, and device therapy, patients can live an active, fulfilling life.

How does High Blood Pressure (Hypertension) damage the heart over time?

Direct Answer: Chronic high blood pressure forces the heart to work harder to pump blood, causing the heart muscle to thicken, stiffen coronary arteries, and significantly increase the risk of heart attacks, stroke, and kidney failure.

Why is Bad Cholesterol (LDL) dangerous for blood vessels?

Direct Answer: High LDL cholesterol deposits fatty plaque along artery walls (atherosclerosis). Over time, plaque restricts blood flow to the heart muscle, and a plaque rupture can instantly trigger a heart attack blood clot.

Can an ECG or Echo be normal even if there is a heart blockage?

Direct Answer: Yes. A resting ECG or Echo may show normal results when artery blockages are partial (e.g., 70% blocked). If you experience chest pain or breathlessness during activity, a Treadmill Test (TMT) or Coronary Angiogram is recommended.

What happens during a Coronary Angiogram test?

Direct Answer: A coronary angiogram is a quick diagnostic procedure performed in a cath lab where a safe contrast dye is injected into coronary arteries via a tiny catheter in the arm or wrist to map exact blockage locations in real time.

What is a 2D Echo test and what does it measure?

Direct Answer: A 2D Echocardiogram uses ultrasound waves to visualize heart valves, measure heart muscle thickness, assess valve leakage/tightness, and evaluate overall pumping power (Ejection Fraction EF%).

When is a 24-Hour Holter Monitor test required?

Direct Answer: A Holter monitor is prescribed when patients experience intermittent dizziness, fainting spells, or heart fluttering that doesn't appear during a brief 5-minute hospital ECG recording.

What is Coronary Angioplasty and Stenting?

Direct Answer: Angioplasty is a minimally invasive procedure where a small balloon is used to open blocked heart arteries and a tiny metal mesh stent is placed to keep the blood vessel permanently open for normal blood flow.

What is TAVR (Transcatheter Aortic Valve Replacement)?

Direct Answer: TAVR is an advanced, non-surgical aortic valve replacement procedure performed through a small keyhole incision in the leg vessel, offering a safe alternative to open-heart surgery for elderly or high-risk patients.

Can a stent be placed after a patient has had Bypass Surgery?

Direct Answer: Yes. If bypass grafts develop blockages years after surgery, interventional cardiologists can safely perform angioplasty and stent placement in bypass grafts or native arteries.

How does a Pacemaker regulate the heart rate?

Direct Answer: A pacemaker is a small implanted device that continuously monitors heart rhythm and sends gentle electrical impulses to stimulate a normal heartbeat whenever the natural heart rate drops dangerously slow.

What is Non-Surgical Device Closure for Hole in Heart (ASD/VSD/PDA)?

Direct Answer: Device closure uses an umbrella-like keyhole plug inserted through a leg blood vessel under X-ray guidance to permanently seal structural holes in the heart without open-heart surgery.
