The heart is one of the hardest working organs in the body,is basically a living pump, it contracts and expands about 100,000 times every day. This permanent stress makes it very vulnerable to diseases.
The risk of heart attack is increased by the lack of C vitamin , but also by smoking,obesity,a high level of cholesterol, lack of exercise, or even genetic predisposition. Other factors of risk can be the air pollutants, chlorinatedwater and other. Another significant cause of ischemic heart disease is the emotional stress, that not only raises the blood pressure, but also increases the quantity of adrenalin.
Concerning the alcohol the opinions are contradictory: some researches show that a glass of red wine or beer a day it’s good for your health,and could also prevent a heart attack. But heavy drinking, however, it’s still consider a cause of cardiovascular diseases.
Recent studies show that the iron contained in red meat is also considered a factor of risk in heart diseases. Moreover, it has been discovered that the mercury is a potent initiator of heart disease.
The prevention of ischemic heart disease or stroke is the same thing as preventing atherosclerosis. We can prevent atherosclerosis eliminating the causes of their injuries, by lowering the level of fats, cholesterol and lipoproteins in the blood.
The strongest protection against heart diseases is a healthy diet. Many studies were made to prove the importance of diet in preventing heart diseases. For example a study showed that the death rate among vegetarian people caused by heart disease is lower. Also people who consumed a large quantity of margarine were more predisposed at a heart attack than people who had a small quantity of margarine. Doctors recommend a diet containing maximum 20% of calories from fat and 10 mg of cholesterol per day(to make a comparison,a hamburger have100 mg of cholesterol).
Another important cause of heart diseases is smoking. In America over 400,000 people die every year killed by smoking and 125,000 of them die from heart diseases. At women who smoke and take oral contraceptives the risk of a heart attack is very high. Passive smoking represents also a danger and may aggravate existing angina.
A very effective way to prevent atherosclerosis are antioxidants. They deactivate free radicals and peroxidized fats preventing them from adhering to existing deposits on the artery walls.
Regular exercise is one of the most important measures in the prevention of heart disease, stroke, hypertension, obesity, and diabetes.
