Why are heart attacks being reported among younger Indians? Apollo Hospitals Group founder and chairman Dr Prathap C Reddy has drawn attention to the long-recognised vulnerability of South Asians, saying people in the region may develop heart disease at a younger age and therefore need to be far more careful.
Speaking in Delhi, Dr Reddy recalled seeing many young patients with heart problems after returning to India. He also referred to the deaths of three Indian doctors in their duty rooms in 1991 and said the episode intensified questions about why apparently young professionals were suffering serious cardiac events.
Dr Reddy linked part of the vulnerability to the possible long-term biological effects of famine and historical deprivation. That statement has attracted attention, but it should not be read as proof that doctors have discovered one final cause of every early heart attack. Modern cardiovascular science points to a combination of ancestry, metabolism, family history, cholesterol, diabetes, blood pressure, smoking, sleep, stress, diet and physical activity.
What Dr Prathap Reddy Said About Early Heart Attacks
Dr Reddy said that when he came to India, he saw many young people with heart problems. He recalled that inactivity, ghee and coconut oil were among the factors blamed after the deaths of the doctors in 1991. He then referred to a theory that a famine centuries ago may have left South Asian populations biologically more vulnerable to heart disease.
His central warning was clear: South Asians can face heart attacks at a younger age and need to take prevention seriously. That broad warning is consistent with a substantial body of research showing that cardiovascular risk can appear earlier among people with roots in India, Pakistan, Bangladesh, Sri Lanka and Nepal.
However, the phrase that famine “altered our genes” needs context. Researchers have studied ideas known as the thrifty gene hypothesis, thrifty phenotype and developmental origins of health and disease. These ideas explore whether generations exposed to undernutrition, or babies who receive inadequate nutrition before birth, may later be more vulnerable to insulin resistance, diabetes and heart disease when food becomes abundant.
Did Doctors Finally Find One Cause of Heart Attacks in Young Indians?
No. There is no single confirmed cause that explains every heart attack in a young Indian. A heart attack usually happens when blood flow through a coronary artery becomes blocked, often after cholesterol-rich plaque ruptures and a clot forms. Why that plaque develops or becomes unstable varies from one person to another.
South Asian ancestry is recognised as a cardiovascular risk enhancer, but ancestry is not destiny. It may interact with several modifiable conditions, including high LDL cholesterol, high blood pressure, diabetes, tobacco use, abdominal fat, inactivity and an unhealthy diet. Some people also inherit conditions such as familial hypercholesterolaemia or elevated lipoprotein(a), which can raise risk even when they appear fit.
The famine explanation is therefore best understood as one possible piece of a much larger scientific puzzle. It does not mean that a famine three centuries ago has been proven to be the direct cause of an individual patient's heart attack today.
Why South Asians Can Develop Heart Disease Earlier
Studies have repeatedly found a higher burden of premature cardiovascular disease in South Asians. Researchers have also found that conventional risk calculators may underestimate that danger because many of the older prediction models included few South Asian participants.
Several patterns can contribute to the earlier risk:
- Type 2 diabetes and insulin resistance may develop at a lower body weight.
- Visceral or abdominal fat can be present even when a person's overall weight looks normal.
- High blood pressure and cholesterol abnormalities can begin before symptoms appear.
- Elevated lipoprotein(a) and inherited cholesterol disorders may run in families.
- Smoking, vaping, poor sleep, inactivity and prolonged work stress add avoidable risk.
- A diet high in refined carbohydrates, deep-fried food, trans fat, excess salt and sugary drinks can worsen metabolic health.

Are Ghee and Coconut Oil the Main Reason?
It is too simple to blame one traditional food. Ghee and coconut oil contain a high proportion of saturated fat, and excessive saturated-fat intake can raise LDL cholesterol in many people. But the total eating pattern matters more than a single ingredient.
Portion size, frequency, overall calorie intake, fibre, vegetables, whole grains, protein choices and the amount of processed or fried food all matter. A person who uses a small quantity of ghee in an otherwise balanced diet does not have the same risk profile as someone who frequently eats fried food, smokes, sleeps poorly and has uncontrolled diabetes.
People with high LDL cholesterol, diabetes or a strong family history should discuss their diet with a qualified clinician or dietitian rather than relying on viral claims that label one oil as either a poison or a cure.
Heart Tests Young Adults Should Discuss with a Doctor
Young adults should not wait for chest pain before learning their basic health numbers. A routine consultation can include blood pressure, weight, waist measurement, fasting glucose or HbA1c and a lipid profile. A doctor will also ask about smoking, exercise, sleep, pregnancy-related complications and heart disease in close relatives.
People with a parent or sibling who had a heart attack at an unusually young age should mention it clearly. Depending on the history, a clinician may consider additional assessment for inherited cholesterol problems or lipoprotein(a). Imaging tests are not automatically required for every healthy young person and should be chosen after a professional risk assessment.

Warning Signs of a Heart Attack at a Young Age
A young age does not rule out a heart attack. Warning signs may include pressure, heaviness, squeezing or burning in the chest; pain spreading to an arm, shoulder, jaw, back or upper abdomen; sudden breathlessness; cold sweating; nausea; unusual weakness; dizziness or fainting.
Symptoms can be less typical in women and people with diabetes. Sudden severe breathlessness, exhaustion, nausea or upper-back discomfort may occur without dramatic chest pain. Anyone with possible heart-attack symptoms should contact emergency medical services immediately. Driving oneself to hospital or waiting for the pain to disappear can waste critical time.
How Young Indians Can Reduce Heart Attack Risk
Prevention begins with consistent habits, not a short detox or one miracle supplement. Adults should build regular movement into the week, combining aerobic activity with strength training according to their health and medical advice. Long sitting periods should be interrupted, especially during desk work.
Meals should emphasise vegetables, pulses, fruit, whole grains, nuts and appropriate sources of protein. Refined carbohydrates, sugary drinks, excess salt, repeated deep-frying and tobacco should be reduced or avoided. Sleep should be treated as part of heart care, not as spare time left after work.
Most importantly, diagnosed high blood pressure, diabetes or cholesterol should be treated consistently. Feeling normal does not mean the condition is harmless. Medicines should never be stopped because a social-media post promises that a home remedy can clean the arteries.
Young Heart Attacks in South Asians FAQs
Did Dr Prathap Reddy discover the final cause of early heart attacks?
No. Dr Reddy highlighted South Asians' vulnerability and discussed a historical famine-related theory. Medical evidence shows that early heart attacks result from several genetic, metabolic, behavioural and environmental factors rather than one final cause.
Can famine affect heart health generations later?
Researchers are studying whether undernutrition before birth and across generations can influence metabolism through developmental and epigenetic pathways. The idea is scientifically plausible, but it does not prove that one historical famine directly causes modern heart attacks.
Can a slim young person have a heart attack?
Yes. Body size alone cannot reveal cholesterol, blood pressure, blood sugar, inherited risk, lipoprotein(a), smoking exposure or coronary plaque. A slim appearance does not replace screening.
At what age should Indians start checking heart risk?
Basic checks such as blood pressure, glucose and cholesterol should begin in early adulthood and may need to start sooner or occur more often when there is diabetes, smoking, obesity or a family history of premature heart disease.
What is the most important step for preventing an early heart attack?
There is no single step for everyone. Knowing and controlling blood pressure, cholesterol and blood sugar, avoiding tobacco, exercising regularly, eating a balanced diet and seeking early medical advice together provide the strongest practical foundation.
What Dr Reddy's Warning Means for Young South Asians
Dr Prathap Reddy's remarks should be treated as a call for earlier prevention, not as a reason for panic or fatalism. South Asians may carry higher risk, but much of the danger can be detected and managed. Young adults should know their family history, check their health numbers, respond quickly to warning signs and build habits that protect the heart for decades.
