Heart attack (myocardial infarction).
During a cardiac arrest, a coronary artery or among its smaller sized branches is all of a sudden blocked. This implies that the part of the heart muscle supplied by this artery loses its blood and oxygen supply. Unless the clog is rapidly gotten rid of, this part of the heart muscle is at risk of dying. A cardiovascular disease is often referred to as a myocardial infarction. When part of the heart muscle is damaged, it is said to be infarcted. The term myocardial infarction indicates broken heart muscle.
