The main causes of heart attack are well known to the average person - smoking, diabetes, hypertension, obesity, low-activity lifestyle.

But there are other reasons that put the heart under attack only in certain circumstances.

Although these situations can not always be avoided, warned - it means armed.

The five unexpected causes of myocardial infarction:.

Reason # 1: extreme cold.

A low temperature causes arteries to narrow, which can lead to a sudden jump in blood pressure. Add here a family quarrel or physical exertion, such as cleaning snow - and you will receive a deadly cocktail for a sick heart.

Every year in the United States raking snow in the cold sends 11,000 people to hospitals, among them at least 1,000 - with cardiovascular diseases.

Reason # 2: sudden load.

Episodes of sudden, strenuous physical activity can cause a heart attack in an untrained or weakened person. It can be quite "harmless" actions, such as transfer with a rebound in basketball or the raising of bags in a supermarket.

People of middle age who are not used to sports loads and physical work in general, should start from a minimum, and not try to beat the records on a par with youth!.

Reason # 3: heavy food.

Festive feast for the future on February 23 and March 8 - a wonderful tradition. But let me remind you that overeating is fraught with serious problems - up to myocardial infarction.

Why can heavy food cause a heart attack? Scientists believe that a rich meal increases the content of adrenaline in the blood, increasing pressure, heart rate and stress on the heart.

If your coronary arteries remember the best times - observe moderation!.

Reason # 4: intense emotions.

Studies have shown that severe anger and grief can cause heart attack. This is probably due to a sudden increase in heart rate and pressure. Since we are all living people, and we live in feelings, it is better to learn how to control them with age.

There is a condition called takotsubo cardiomyopathy (broken heart syndrome), which can simulate a heart attack, but differs from it. This syndrome is more common in women during a period of intense grief and distress. As a result of spasm of the coronary arteries, heart failure develops, which requires a doctor.

Reason # 5: other diseases.

Even if you have a diagnosis of a disease that seems completely unrelated to the heart, the risk of a heart attack can not be ruled out.

Unfortunately, the role of many diseases and conditions in the development of a heart attack is often underestimated.

Among the possible causes of heart attack doctors call:.

• Rheumatoid arthritis, lupus and other diseases that can cause inflammation in the blood vessels.

• Post-irradiation of the chest.

• Sleep apnea (the condition is closely related to cardiovascular diseases).

• Gestational diabetes in pregnancy.

• Pre-eclampsia.
