Acute Myocardial Infarction (AMI), commonly referred to as a heart attack, is a disorder in which damage to an area of heart muscle occurs because of an inadequate supply of oxygen to that area leading to damage or death of cells. The damaged tissue results in a permanent loss of contraction of this portion of the heart muscle. AMI occurs in approximately 2 out of 1,000 people per year. It is a major cause of sudden death in adults. Currently there is an interest for the earliest possible determination of AMI for patients admitted to the emergency room with chest pains, both to determine which patients can be safely sent home and which need further care, and because for those how suffered an AMI, treatment with thrombolytic therapy is most beneficial the earlier after an AMI the treatment is instituted.
