Know the Risk Factors which leads to Heart Attack

In India, almost Four people die of heart attack every minute in India and the age group is mainly between 30 and 50. Twenty-five per cent of heart attack deaths occur in people less than 40. Nine hunderd people under 30 die due to heart disease in India every day. Let us look at the most common causes being attributed to heart attack in young persons.


Aging increases your risk of damaged and narrowed arteries and weakened or thickened heart muscle.


Men are generally at greater risk of heart disease. However, women’s risk increases after menopause.

Family history

A family history of heart disease increases your risk of coronary artery disease, especially if a parent developed it at an early age (before age 55 for a male relative, such as your brother or father, and 65 for a female relative, such as your mother or sister)


What begins as a fashion statement in college days later turns out to be an indispensable addiction. It is the single largest risk factor for a young individual developing Myocardial Infarction (MI).

Smokers not only develop MI earlier but are at a two-fold increased risk compared to non-smokers and at a four-fold-increased risk of sudden death due to MI. The corresponding risks are higher in smoking women.

Nicotine constricts your blood vessels, and carbon monoxide can damage their inner lining, making them more susceptible to atherosclerosis. Heart attacks are more common in smokers than in nonsmokers.

Not only smoking, all forms of tobacco consumption are equally dangerous. Tobacco causes the blood vessels to be stiff and less elastic, increases the tendency for blood clot and blocks the flow in the coronary arteries. A common misconception is that people who smoke occasionally are not at risk. Once a person quits smoking, it will take three years for the body and heart to recover from the effects of tobacco, so you can imagine the consequences of the person continuing to smoke.

High cholesterol levels

While some cholesterol is necessary for good health, too much cholesterol is bad. Excess cholesterol deposits enter the inner lining of the coronary arteries gradually, building from tiny crystals into larger deposits making the arteries narrower and consequently blood supply to the heart gets obstructed leading to MI.

Though the total cholesterol levels are a predictor of heart disease, many Indians who develop MI have normal cholesterol levels. This is because even though their total cholesterol levels are normal, they have low levels of good cholesterol (HDL cholesterol) and a very unique, dangerous type of bad cholesterol (LDL) which has a higher blood clot forming tendency.

Diabetes Mellitus

The rampant rise in the incidence of diabetes is a major factor in youngsters developing MI. Compared to non-diabetics, a diabetic with myocardial infarction develops a large MI (a larger portion of the heart is affected), has the risk of sudden cardiac death, responds poorly to treatment and has a higher risk of developing re-infarction.

Diabetics have an increased tendency to form blood clots (similar to smokers), have multiple blocks and may also have involvement of blood vessels supplying the brain and legs.


Changing food habits leading to increased salt consumption, stress and a sedentary lifestyle have all contributed to the rise of young hyper-tensives. Most of us grab snacks such as namkeens and samosas between meals when hungry… not only do they have a high salt content but they are also sources of trans-fat. People with high blood pressure are likely to develop CAD because high BP places an added force on the artery walls and over time, the extra pressure can damage the arteries. These injured arteries are most likely to become narrowed and hardened by fatty deposits.


We are in the grip of an obesity epidemic. Sadly, the divide between the overnourished and the malnourished is deepening in India. Obesity is a combination of poor physical activity, stress and an unhealthy food culture. With obesity comes the risk of developing diabetes, high blood pressure and high cholesterol. Indian obesity is different. We may not be obese overall, but have abdominal obesity… excess fat deposit around the belly. Unfortunately, it is this belly fat, also called ‘apple type obesity,’ which is dangerous because all metabolic byproducts of visceral fat cells easily enter the liver and get stored as fat.

Unhealthy food habits

Junk food joints have become hang-outs for college students and young professionals. We are always under the impression that Indian food is healthy because Indians are largely vegetarians. However, the Indian vegetarian recipe calls for liberal use of milk, ghee, oil and decreased intake of fruits and vegetables, leading to a higher intake of refined carbohydrate, saturated fat and trans-fat.

Physical inactivity

Physical inactivity not only causes heart disease but also hypertension, diabetes and obesity. Physical inactivity starts from school as modern day teaching hardly stresses the importance of physical education.

Eighty per cent of our young population is physically inactive; the remaining 20% that frequents the gyms concentrates on muscle building rather than aerobic training.

Youngsters have to undertake aerobic physical activity for 30-60 minutes a day for at least five days a week.


Many studies reveal that the recent stress in personal or professional lives leads to MI. With most of the work happening from the desk and at unearthly working hours and due to poor sleep quality, young IT professionals and BPO employees have high stress and run the risk of developing heart diseases if they also possess any of the above mentioned risk factors. Management of stress is very often preached, but hardly practised and is difficult to implement.


Indians are genetically prone to heart disease. Even NRIs living abroad for many generations continue to have the risk because of their genes. Indians have relatively small coronary arteries, making them more vulnerable to the disease even with less severe atherosclerotic disease than our western counterparts. The gene, if any, that is responsible for CAD is yet to be decoded.
