Heart Attack Symptoms & Warning Signs
Every Person Should Know

Every year, hundreds of thousands of Indians die from heart attacks that could have been treated — if only the warning signs had been recognised in time. A heart attack (myocardial infarction) occurs when blood flow to a part of the heart is blocked, causing heart muscle to begin dying within minutes. Knowing the symptoms and acting fast can save your life or the life of someone you love.

1. Classic Heart Attack Symptoms

The most well-known symptom is chest pain or discomfort — but a heart attack can feel different for different people. Here are the six most common warning signs:

The chest discomfort during a heart attack is often described as a feeling of squeezing, fullness, pressure or pain in the centre of the chest that lasts more than a few minutes, or that goes away and comes back. It may also spread to the left arm, both arms, the back, neck, jaw or stomach.

2. Symptoms in Women Are Different

Women are more likely than men to experience heart attack symptoms that are not chest pain. This is one reason heart attacks in women are frequently missed or diagnosed late. Women may experience:

• Unusual fatigue — extreme tiredness for several days before the attack
• Upper back, shoulder or jaw pain without any chest discomfort
• Nausea, vomiting or indigestion that doesn't improve
• Sleep disturbances in the days leading up to the attack
• Shortness of breath even without physical exertion
• Anxiety or a sense of doom without an obvious cause

Women with diabetes, high blood pressure or a family history of heart disease are at especially high risk and should be extra vigilant about these atypical symptoms.

3. Silent Heart Attacks

A silent heart attack (silent myocardial infarction) causes little or no symptoms — or symptoms so mild they are easily confused with indigestion, muscle pain or fatigue. Many people only discover they have had a silent heart attack during a routine ECG. Silent heart attacks are more common in people with diabetes and are equally dangerous as symptomatic heart attacks. Regular cardiac check-ups are essential if you have any risk factors.

4. When to Call Emergency

Do not drive yourself to hospital. Call for help and chew one aspirin (325mg) if available and you are not allergic — this can help reduce clot formation while waiting for emergency care.

At Charak Hospital, our 24/7 cardiac emergency team can perform primary angioplasty (primary PCI) — the gold-standard treatment for heart attacks — within minutes of arrival. Time is heart muscle. Every minute counts.

5. Who Is at High Risk?

You are at higher risk of a heart attack if you have one or more of the following:

• High blood pressure (hypertension) — damages artery walls over time
• High cholesterol — leads to plaque build-up in arteries
• Diabetes — doubles the risk of heart disease
• Smoking — one of the strongest risk factors
• Obesity — especially abdominal (belly) fat
• Family history — a first-degree relative with heart disease before age 55
• Sedentary lifestyle — physical inactivity significantly increases risk
• Stress — chronic stress raises blood pressure and inflammation
• Age — men over 45, women over 55 are at higher risk

6. Prevention Tips from Our Cardiologists

Diet

Reduce salt, saturated fats and refined sugar. Increase vegetables, fruits, whole grains, nuts and fish. The Mediterranean-style diet has strong evidence for reducing heart attack risk. Avoid fried and processed foods which are common in Indian diets.

Exercise

Aim for at least 150 minutes of moderate exercise per week — brisk walking, swimming or cycling. Even 30 minutes of walking daily makes a significant difference to heart health.

Regular Check-ups

Annual health checks for blood pressure, blood sugar (HbA1c) and lipid profile are essential if you are over 40 or have any risk factor. Early detection of hypertension or high cholesterol allows treatment before heart damage occurs.

Quit Smoking

The risk of heart attack begins to fall within 24 hours of stopping smoking and returns to near-normal within 1–2 years. Our team can help you access cessation support.
