It’s a sight that shakes us to the core: a seemingly fit youngster collapsing mid-dance at a wedding, a gym enthusiast gasping for breath before falling unconscious, or a player dropping on the field. These shocking incidents are a grim reminder that heart attacks are no longer confined to older adults.

Increasingly, young Indians are falling victim, and hidden metabolic risks—particularly rising triglycerides—are playing a dangerous role. According to Prof. Rajeev Narang, Head of Cardiology at AIIMS, elevated triglycerides not only raise the risk of heart attacks but can also trigger pancreatitis, making them a dual threat that cannot be ignored.

Triglycerides are a type of fat (lipid) found in your blood. They are the body’s main form of stored energy. When you eat, your body converts any calories it does not need immediately into triglycerides, which are stored in fat cells. Later, hormones release them for energy between meals.

On the occasion of World Heart Day, which emphasises global awareness about cardiovascular health, experts are urging young adults to take early action to protect their hearts. The theme of this year’s World Heart Day reminds everyone that heart health is a responsibility, not a later-life concern, and that awareness about hidden risks like high triglycerides can save lives.

“What many people overlook is that heart disease gives early warning signals,” Prof. Narang explains.

Chest pain while walking, or angina, can indicate blocked arteries, while breathlessness signals a weakening heart muscle. Swelling in the feet or fatigue during simple activities are other red flags that should prompt immediate medical attention.

While cholesterol often dominates conversations about heart health, triglycerides are just as important. High triglyceride levels can silently raise the risk of heart disease and, in some cases, provoke pancreatitis—a potentially serious inflammation of the pancreas. These abnormalities are commonly seen in people with diabetes or thyroid disorders. “Keeping triglycerides under control is crucial, just like cholesterol. Ignoring them can silently fuel heart problems and pancreatic complications in young adults,” he emphasizes.

Lifestyle factors compound the risk. Diabetes, high blood pressure, smoking, sedentary habits, poor diet low in fruits and vegetables, abdominal obesity, and chronic stress all contribute to arterial damage. “The more risk factors present, the higher the likelihood of a heart attack,” Prof. Narang warns.

Stress, genetics, and undiagnosed conditions add another layer of danger. Chronic stress elevates hormones like epinephrine and norepinephrine, putting additional strain on the heart. A family history of early heart disease increases risk, and certain genetic disorders can disturb cholesterol levels or heart rhythms, sometimes causing sudden cardiac death. Conditions like hypertrophic cardiomyopathy—where the heart muscle thickens—can also prove fatal if undetected.

High blood pressure, the so-called “silent killer,” quietly damages arteries over time until symptoms appear, such as headaches, swelling, or difficulty walking. Left unchecked, it can precipitate heart attacks and strokes, which is why routine monitoring is essential, even for the young and apparently healthy.

Despite these worrying trends, Prof. Narang emphasizes that much of the risk is preventable. 

“A healthy lifestyle, regular exercise, balanced diet, stress management, and routine medical check-ups can dramatically reduce the likelihood of heart disease,” he says.

For young Indians, the warning is urgent, especially on World Heart Day: triglycerides, cholesterol, and lifestyle choices are not issues for the future—they are responsibilities that start now. Monitoring triglycerides is vital, not just for heart health but also to prevent pancreatic complications, giving young adults a real chance to avoid sudden, preventable tragedies.
