Acute Myocardial Infarction 

An acute process of prolonged myocardial ischemia of sufficient severity and duration to result in permanent damage to heart muscle; commonly known as a “heart attack”. This damage occurs when part of the heart muscle is deprived of blood flow, usually as the result of a blockage that stops flow down one of the major arteries that supply the heart (coronary artery). A scar usually forms in the heart
