Causes of Heart Attack
With advancing age, increased amounts of cholesterol and calcium being deposited in the walls of the coronary arteries (coronary arteries). Such deposits termed plaques. The process termed atherosclerosis (hardening of the arteries). Smoking and cholesterol diet combined with lack of exercise can accelerate this process.
Plaques grow; they begin to inhibit blood flow. Growth of plaque in the inner core is surrounded by a hard shell and soft with cholesterol. Such plaques are likely to crack and expose the interior of cholesterol. Loose pieces of plaque can build. Artery may be partially or completely cut off the loose pieces. Blocked artery is more; most of the damage is on your mind.
Atherosclerosis of the coronary arteries
This is the most common cause of heart attack, and the degree of atherosclerosis increases with the incidence of a number of risk factors. The more risk factors you have, the greater the likelihood that you have atherosclerosis. The most common risk factors are:
Coronary artery disease without atherosclerosis
Coronary arteries can occasionally be blocked for reasons other than atherosclerosis. It may be inflammatory disease of the arteries (vasculitis), damage to blood vessels and diseases that cause thickening of the coronary arteries. Other causes are problems with circulation and oxygen supply due to external influences such as cocaine use. Heart attacks can also come as a complication after bypass surgery or catheterization. Certain heart problems that are present from birth, can also lead to heart attacks.
Overall, however, this small group. Most cases of heart attacks caused by atherosclerosis.

This is the most common cause of heart attack, and the degree of atherosclerosis increases with the incidence of a number of risk factors. The more risk factors you have, the greater the likelihood that you have atherosclerosis. The most common risk factors are:
- Inheritance - accumulation of cases of heart disease in the family
- Men are more prone than women and have a heart attack on average 10 years earlier than women. For both sexes, the risk of myocardial infarction with increasing age
- High cholesterol - especially the high levels of the "bad cholesterol" (LDL, low-density lipoprotein) and low levels of 'good cholesterol (HDL, high-density lipoprotein)
- Cigarette smoking or other tobacco use as cigars, snuff and chewing tobacco. Cigarette use is the most important of the controllable risk factors
- High blood pressure
- Diabetes
- Obesity or overweight
- Physical inactivity, lack of regular exercise
- High fat content in the diet
- Much stress
- Type-A personality - hard-working, perfectionist
