Myocardial Infarction

Infarction of the lower region of the myocardium: dark red, the necrotic area of the wall of the heart muscle. Myocardial infarction (MI is an abbreviation) is a necrosis (cell death) of a portion of heart muscle. In common parlance, we call most often a heart attack. It occurs when one or more coronary arteries become blocked, cells in the myocardium (the muscle forming the heart) irrigated by this (these) artery (s) are then more oxygen, causing their suffering (pain) and may lead to their death (myocardial scar that usually persist). The area “infarcted” does incur more correctly.
