Overview
Acute myocardial infarction (AMI or MI), more commonly known as a heart attack, is a medical condition that occurs when the blood supply to a part of the heart muscle or myocardium is interrupted. The resulting ischemia or oxygen shortage causes damage and / or irreversible death (necrosis) of the myocardium (heart muscle). It is a medical emergency, and the leading cause of death for both men and women worldwide, particularly in developed countries.[1] The term myocardial infarction is derived from myocardium (the heart muscle) and infarction (tissue death due to oxygen starvation). The phrase "heart attack" is sometimes used incorrectly to describe sudden cardiac death, which may or may not be the result of acute myocardial infarction.
There are two types of acute MI: ST elevation myocardial infarction (STEMI), the topic of this chapter and non ST elevation MI (NSTEMI) which is discussed in another chapter of WikiDoc. ST elevation myocardial infarction refers to an electrocardiographic pattern in which the ST segments are elevated reflecting complete epicardial vessel occlusion. Once the vessel is opened by percutaneous coronary angioplasty, the ST segments can remain elevated due to absence of perfusion or flow into the myocardium itself. At this point in the evolution of the ST elevation MI, the epicardial artery is open, but the capillary network is occluded due to swelling, embolization, and / or vasospasm.
Non ST elevation myocardial infarction refers to a disease state in which the epicardial artery is open, but there is inadequate blood flow to the myocardium which results in an electrocardiographic pattern of ST segment depression. While ST elevation reflects transmural injury, ST depression may reflect ongoing subendocardial ischemia. Inadequate blood flow to the muscle may be due to embolization of material downstream into the myocardium or a restriction of blood flow due to severe narrowing of the epicardial artery. [2] [3] [4]
