What people call “heart attack” is one of the chief causes of death in the Western World. In three out of four cases, a victim is a man, and the age is usually between fifty and seventy years. A typical heart attack is often caused by “coronary thrombosis”. In fact, many people simply call it a coronary’. This is because it starts with the coronary arteries, the two blood supply the heart with blood.
When one of these arteries become clogged, the blood supply of a part of the heart is shut off. The tissue in this part of the heart at once to degenerate and die, just the same as if it had been wounded.
When one coronary artery becomes clogged, the smaller branches of the other artery take up the work over a period of time. After a while, most of the areas of the heart that have been cut off receive the blood they need.
If the second artery can carry on the work for both, the person lives. Fortunately, in most cases the second artery can do the job, providing the heart is spared from all strain during this period.
In many patients, a heart attack occurs after seme unusual physical exertion, emotional upset, exposure to extreme cold, eating a heavy meal—or any situation where the heart is called upon to do a bigger job than usual. These things do not actually cause a heart attack, but there is some relationship. In many cases, however, an attack can occur while a person is at rest.
The symptoms of a heart attack usually include pain beneath the breastbone. But the pain may also first be felt in the arms, neck, or left shoulder. There are sweating and shortness of breath. The victim may become pale and be in a state of shock, and the pulse may become weak. A person should immediately call a doctor if such symptoms appear.
