A 37-year-old man who reportedly ran 5 kilometres daily, avoided junk food and maintained an active lifestyle still required two heart stents, drawing attention to the hidden role genetics can play in cardiovascular disease.

Health experts say the case is a reminder that fitness alone does not always guarantee protection from heart blockages.

Doctors noted that hereditary risk factors, cholesterol disorders and silent plaque build-up can affect even young and apparently healthy individuals.

Healthy habits are vital, but not everything

Medical specialists stress that regular exercise, balanced diet and avoiding smoking remain crucial for heart health.

However, family history, inherited cholesterol abnormalities and metabolic conditions can still increase risk despite disciplined habits.

Some individuals may develop artery narrowing without obvious warning signs.

Young adults should not ignore screening

Experts increasingly advise adults with a family history of early heart disease to undergo regular health checks.

These may include blood pressure monitoring, cholesterol profile, blood sugar levels and cardiac assessments when recommended.

Early detection can often prevent serious complications such as heart attack.

Symptoms can be subtle

Doctors say chest discomfort, breathlessness, unusual fatigue, jaw pain or reduced exercise tolerance should never be ignored, especially if persistent.

In some cases, people may have significant blockages with minimal symptoms until a major event occurs.

Genetics and lifestyle both matter

Cardiologists emphasise that heart disease usually results from a combination of genetic predisposition and lifestyle factors.

A person who appears fit externally may still need medical evaluation if risk markers are present.

Key takeaway for younger Indians

With heart disease affecting Indians at younger ages, experts say prevention should begin early through exercise, healthy food, stress control and regular screening.

Being active is powerful protection — but knowing family history and checking risk factors can be lifesaving.
