The Silent Epidemic: Why Indians Are at Higher Risk of Sudden Cardiac Arrest – A Wake-Up Call

Have you ever thought a healthy-looking young person could collapse suddenly without warning? It may sound unbelievable, but this is the terrifying reality of Sudden Cardiac Arrest (SCA), a growing and silent epidemic in India.

According to the Indian Heart Association (IHA), India holds nearly 60% of the global burden of heart disease, despite having less than 20% of the world’s population. What’s even more alarming is the sharp 13% increase in sudden cardiac arrest among Indians in their mid-30s to mid-40s, as reported by the American Heart Journal. And in 2025, this upward trend continues, especially among younger adults; driven by modern lifestyle choices, post-COVID complications, and rising health risks like diabetes, obesity, smoking, and stress.

Dr. Biju Govind, MBBS, MD, DM (Cardiology), Senior Consultant Interventional Cardiologist, Sri Sri Holistic Hospitals, Hyderabad, who explains how sudden cardiac arrest occurs and how we can protect ourselves.

What Happens During a Sudden Cardiac Arrest?

Sudden cardiac arrest is not the same as a heart attack. It occurs when the heart’s electrical system fails, causing it to stop beating suddenly. This prevents blood from flowing to the brain and other vital organs.
“The heart normally beats 60–100 times per minute,” says Dr. Biju. “Any major variation, either too fast (tachycardia) or too slow (bradycardia) can be dangerous. These are called arrhythmias and, if not treated within minutes, can at times lead to death.” People with a family history of heart problems, a history of high cholesterol, or increased heart rate should be especially careful.

Why Are Young Indians at Greater Risk?

Today’s lifestyle is a major culprit. The combination of long sitting hours, junk food, and a high- stress levels is damaging the hearts of young Indians.
● Smoking (both active and passive) causes narrowing of blood vessels, making it harder for the heart to function.
● Diabetes and obesity are growing rapidly in India and are closely linked to heart disease.
● Metabolic syndrome, which includes high blood pressure, high blood sugar, high cholesterol, and obesity dramatically raises the risk of heart attacks and SCA.

Genetics also plays a role. “If someone has high LDL cholesterol (above 190) and a family history of heart disease before age 50, they may have a genetic condition called familial hypercholesterolemia,” Dr. Biju explains.

Don’t Ignore These Warning Signs
SCA often comes without any warning. But sometimes, there are signs; although they may be subtle or easily misunderstood.
● Chest pain that lasts more than 10 minutes
● Pain in the jaw or left hand
● Sweating, dizziness, or shortness of breath
● Fatigue or unexplained giddiness, especially in women
● It’s important to remember that 50% of women don’t experience chest pain during a cardiac event. If in doubt, always seek medical help.
So, How Do We Prevent This?
Preventing heart disease starts with regular health check-ups, even for young adults. “After age 18, check your blood pressure once a year. Aim for below 130/80 mmHg,” advises Dr. Biju.
Here are simple lifestyle changes to lower your risk:
● Exercise: Aim to walk at least 10,000 steps a day to improve heart health.
● Healthy Diet: Avoid red meat (high in saturated fat). Choose oils rich in polyunsaturated fats like sunflower or olive oil.
● Stress Management: Practicing yoga and meditation daily can help manage stress—a silent heart killer.
● Cholesterol Control: Keep total cholesterol below 200, and LDL below 100.
● Sugar Monitoring: Ensure your fasting blood sugar is below 100 and your 3-month average (HbA1c) stays under 5.7.
