Heart attacks

A heart attack is a condition that occurs when the blood flow to the heart is blocked. The blockage happens mainly by the accumulation of substances such as cholesterol and fat, forming plaque coronary arteries that feed the heart muscle. Medically known as myocardial infarction, the blocked coronary artery deprives the heart of oxygen and blood.
