A heart attack (myocardial infarction) occurs when blood flow to a part of the heart muscle is blocked — usually by a blood clot forming inside a coronary artery. Without blood supply, the affected muscle begins to die. Warning signs include crushing chest pain, pain radiating to the left arm or jaw, shortness of breath, cold sweats, and nausea. A heart attack is a medical emergency — call 112 immediately. Early intervention with angioplasty or clot-busting drugs can save significant heart muscle.
Heart failure does not mean the heart has stopped — it means the heart muscle is too weak or too stiff to pump blood efficiently around the body. Symptoms include persistent breathlessness (especially when lying flat), swollen ankles or legs, extreme fatigue, and reduced ability to exercise. Heart failure can be managed effectively with medications, device therapy (such as CRT or AICD), and lifestyle changes under expert cardiology care.
Coronary artery disease is the build-up of plaque (cholesterol, calcium, and fatty deposits) inside the coronary arteries that supply blood to the heart. This narrows the arteries and reduces blood flow, causing chest pain (angina), breathlessness, and — if a plaque ruptures — a heart attack. CAD is the leading cause of heart attacks worldwide and can be treated with medications, angioplasty, or bypass surgery.
Cardiac arrhythmia is an abnormal heart rhythm — the heart may beat too fast (tachycardia), too slowly (bradycardia), or irregularly. Common arrhythmias include atrial fibrillation (AF), ventricular tachycardia, and heart block. Symptoms include palpitations, dizziness, fainting, and breathlessness. Treatment options range from medications to ablation procedures or device implantation (pacemaker or AICD).
Valvular heart disease occurs when one or more of the heart's four valves (aortic, mitral, pulmonary, tricuspid) are damaged and do not open or close properly. This forces the heart to work harder, which can eventually lead to heart failure. It may be treated with medication, catheter-based valve repair or replacement, or open-heart surgery, depending on severity.
Angioplasty — medically known as Percutaneous Transluminal Coronary Angioplasty (PTCA) — is a minimally invasive procedure to open blocked or narrowed coronary arteries. A thin flexible tube (catheter) is inserted through the wrist (radial) or groin (femoral), guided to the blocked artery, and a small balloon is inflated to open the blockage. A metal mesh tube called a stent is usually placed to keep the artery open permanently. The procedure typically takes 30–90 minutes and often requires just one or two days of hospitalisation.
Coronary angiography is a diagnostic procedure that uses X-ray imaging and a contrast dye injected through a catheter to visualise the coronary arteries and detect blockages or narrowing. It is the gold standard test for diagnosing coronary artery disease and is usually performed before angioplasty or bypass surgery.
A pacemaker is a small battery-powered device — roughly the size of a matchbox — implanted under the skin near the collarbone. It continuously monitors the heart's rhythm and delivers tiny electrical impulses through leads to the heart muscle whenever it detects that the heart is beating too slowly or missing beats. Pacemakers significantly improve quality of life for patients with bradycardia, heart block, and certain types of heart failure. Modern pacemakers can last 8–12 years before the battery needs replacing.
An AICD (also called ICD) is an implantable device similar to a pacemaker but with the added ability to deliver a high-energy electric shock to the heart if it detects a life-threatening arrhythmia such as ventricular fibrillation or ventricular tachycardia. This shock restores a normal rhythm and can prevent sudden cardiac death. AICDs are recommended for patients who have survived a cardiac arrest, have severely reduced heart function (ejection fraction below 35%), or have inherited conditions that increase the risk of sudden death.
CRT is a specialised type of pacemaker used in patients with heart failure and an electrical conduction problem that causes the left and right sides of the heart to beat out of sync. CRT coordinates the contractions of both sides simultaneously, improving the heart's pumping efficiency. In some patients, CRT is combined with an AICD (called CRT-D), providing both synchronisation and protection from sudden cardiac death.
A coronary stent is a tiny expandable wire-mesh tube placed inside a coronary artery during angioplasty to hold it open after a balloon has widened a blockage. Modern drug-eluting stents (DES) are coated with medication that prevents scar tissue from re-blocking the artery. After stenting, patients are typically prescribed dual antiplatelet therapy (blood-thinning medications) for 6–12 months.
An echocardiogram is an ultrasound scan of the heart that uses sound waves to create real-time images of the heart's structure and function. It shows the heart's size, the strength of the pumping action (ejection fraction), valve function, and any structural abnormalities — without radiation. It is one of the most important and commonly used cardiac diagnostic tools.
A Holter monitor is a portable ECG device worn for 24–48 hours (sometimes longer) to continuously record the heart's electrical activity. It is used to detect intermittent arrhythmias, palpitations, or unexplained dizziness that may not be captured during a standard in-clinic ECG.
Early warning signs of a heart attack include: (1) Chest pain, tightness, pressure, or heaviness lasting more than a few minutes; (2) Pain spreading to the left arm, jaw, neck, or back; (3) Shortness of breath; (4) Cold sweats or sudden nausea; (5) Unexplained fatigue or lightheadedness. Women may experience atypical symptoms such as nausea, jaw pain, or extreme tiredness without classic chest pain. If you experience any of these, call emergency services immediately — do not drive yourself to hospital.
Sudden cardiac arrest occurs when the heart's electrical system malfunctions and the heart stops beating unexpectedly. It is not the same as a heart attack: a heart attack is a plumbing problem (blocked artery), while cardiac arrest is an electrical problem (chaotic or absent rhythm). Cardiac arrest is fatal within minutes without CPR and defibrillation. An AICD can detect and treat this automatically from inside the body.
Key symptoms of heart failure that require immediate medical attention include: sudden worsening of breathlessness, inability to lie flat without breathlessness, rapidly swelling ankles or legs, sudden unexpected weight gain of more than 2 kg in 2–3 days (from fluid retention), persistent cough, reduced urine output, and increasing fatigue.
You should see a cardiologist if you have: chest pain or discomfort; unexplained shortness of breath; palpitations or irregular heartbeat; dizziness or fainting; swollen legs; family history of early heart disease (before age 55 in men, 65 in women); or risk factors such as hypertension, diabetes, high cholesterol, obesity, or smoking. Early detection saves lives
Not always — chest pain can originate from the heart, lungs, oesophagus, muscles, ribs, or anxiety. However, any new, unexplained, or severe chest pain must be evaluated by a doctor promptly. Cardiac chest pain is typically described as a pressure, squeezing, or heaviness, often triggered by exertion and relieved by rest. Never dismiss chest pain without professional assessment.
The major modifiable risk factors for heart disease are: high blood pressure (hypertension), high LDL cholesterol, type 2 diabetes, smoking, obesity, physical inactivity, an unhealthy diet, excessive alcohol, and chronic stress. Non-modifiable risk factors include age, gender (men at higher risk at a younger age), and family history. Managing modifiable risk factors through lifestyle changes and medications can dramatically reduce the risk of heart attack and stroke
Yes — up to 80% of premature heart disease and strokes are preventable through healthy lifestyle habits: eating a balanced diet low in saturated fats and salt, exercising at least 150 minutes per week, not smoking, limiting alcohol, managing weight, controlling blood pressure, cholesterol, and blood sugar, and attending regular cardiac health check-ups.
Obesity increases the risk of hypertension, type 2 diabetes, high cholesterol, sleep apnoea, and coronary artery disease. Excess body fat — especially abdominal fat — triggers systemic inflammation and insulin resistance, both of which directly damage blood vessels and accelerate plaque build-up in the arteries. Even a 5–10% reduction in body weight can significantly lower blood pressure, cholesterol, and cardiac risk.
Chronic stress contributes to heart disease indirectly by raising blood pressure, increasing cortisol levels (which can raise blood sugar and cholesterol), and promoting unhealthy behaviours like smoking, poor eating, and inactivity. Severe acute stress (such as bereavement or shock) can also trigger a real heart attack or a stress-induced cardiomyopathy called Takotsubo syndrome.
In most cases, yes — exercise is actively encouraged for cardiac patients and is a cornerstone of cardiac rehabilitation. The key is to exercise at the right intensity, type, and duration based on your specific condition. Dr. Sukriti Bhalla tailors individual activity guidelines for every patient based on their cardiac assessment and procedure history.

Please bring any previous ECG or Echo reports, blood test results (lipid profile, HbA1c, kidney function), a list of current medications with dosages, any prior discharge summaries or cardiac procedure reports, and your insurance card if applicable. This helps Dr. Bhalla provide the most accurate and personalised assessment.
Cardiologist-guided medical weight loss is a medically supervised programme led by Dr. Sukriti Bhalla that combines a thorough cardiac and metabolic health assessment with a personalised diet, lifestyle, and medical management plan. Unlike generic diet programmes, it is specifically designed to ensure that weight loss is achieved safely — without placing any additional strain on the heart.
The programme is suitable for individuals who are overweight or obese — especially those with heart disease, hypertension, diabetes, high cholesterol, or metabolic syndrome. It is also recommended for patients who have tried conventional dieting without sustainable results, and for anyone who wants to lose weight under proper cardiac supervision.
Losing even 5–10% of body weight can lower blood pressure, improve cholesterol levels, reduce blood sugar, decrease inflammation, and significantly reduce the risk of heart attack, stroke, and heart failure. Under Dr. Bhalla's supervision, weight loss is achieved in a way that actively protects and strengthens cardiovascular function throughout the journey.
Medically approved weight management medications may be considered on a case-by-case basis, only when clinically appropriate and safe for your heart. The primary focus is on sustainable dietary modification, physical activity, and behaviour change — with any medical treatment personalised to your cardiac profile.
A normal resting heart rate for adults is between 60 and 100 beats per minute (bpm). Well-trained athletes may have a resting heart rate as low as 40–50 bpm. A consistently high resting rate (above 100 bpm) or a persistently low one (below 50 bpm with symptoms) warrants medical evaluation.
A normal blood pressure is below 120/80 mmHg. A reading of 120–129/<80 is considered elevated; 130–139/80–89 is Stage 1 hypertension; and 140/90 or above is Stage 2 hypertension requiring treatment. Blood pressure consistently above 180/120 mmHg is a hypertensive crisis — seek emergency care immediately.
Ejection fraction (EF) is the percentage of blood the heart pumps out with each beat. A normal EF is 55–70%. An EF below 40% indicates reduced heart function (heart failure with reduced EF), which significantly increases the risk of dangerous arrhythmias and may require device therapy such as an AICD or CRT device. Regular Echo monitoring helps track EF changes over time.
LDL (low-density lipoprotein) is the 'bad' cholesterol — it deposits plaque in artery walls, causing narrowing and blockages. HDL (high-density lipoprotein) is the 'good' cholesterol — it carries cholesterol away from the arteries back to the liver. High LDL and low HDL are key risk factors for coronary artery disease. Triglycerides are another important fat in the blood that should also be kept in check.
Yes. While heart disease is more common in older adults, heart attacks in people under 40 are increasing — driven by obesity, sedentary lifestyles, uncontrolled diabetes, hypertension, smoking, cocaine use, and genetic conditions such as familial hypercholesterolaemia. Young people often delay seeking help because they do not believe they are at risk — which worsens outcomes. Any chest pain or cardiac symptoms at any age should be evaluated promptly.
Yes, family history is a significant non-modifiable risk factor for heart disease. If a parent or sibling had a heart attack or coronary artery disease before age 55 (in men) or 65 (in women), your own risk is substantially higher. Genetic conditions such as familial hypercholesterolaemia (very high LDL from birth), hypertrophic cardiomyopathy, and certain arrhythmias are also directly inherited. Early screening is strongly recommended if you have a family history.
Cardiac rehabilitation is a medically supervised programme combining structured exercise training, heart-healthy education, and psychological support to help patients recover after a heart attack, angioplasty, bypass surgery, or heart failure admission. Research shows it reduces the risk of a second cardiac event by up to 25% and significantly improves exercise capacity and quality of life. Dr. Sukriti Bhalla incorporates cardiac rehab principles into every patient's personalised post-procedure care plan.
