Heart attack, also known as myocardial infarction, is a condition wherein the normal blood supply to a part of the heart is disrupted, which, in turn, causes the cells in this part to die. In simple words, a heart attack is caused as a result of blocked blood flow to the heart. Such a problem can cause serious damage to the individuals health and even result in death at times.
Basically, heart attack is caused as a result of atherosclerosis―a health condition marked by fatty deposits in the arterial walls, which cause the arteries to become narrow. The resultant pressure causes these arteries to rupture and releases some substances in the bloodstream, which, in turn, causes the blood to clot and hampers its flow. Statistics reveal that the total number of deaths attributed to heart attacks in the United States exceeds the total number of cancer-related deaths in the country.
