It occurs when myocardial tissues are abruptly and severely deprived of oxygen. An acute myocardial infarction, also called a heart attack, happens when a blood vessel in the heart suddenly becomes blocked. Blood vessels carry blood and oxygen. When a blood vessel in the heart gets blocked, blood cannot get to part of the heart. This part of the heart does not get enough oxygen. Laboratory tests used in the diagnosis of AMI include the following: Cardiac biomarkers/enzymes: The American College of Cardiology/American Heart Association (ACC/AHA) and the European Society of Cardiology (ESC) guidelines recommend that cardiac biomarkers should be measured at presentation in patients with suspected MI, and that the only biomarker that is recommended to be used for… MYOCARDIAL INFARCTION MI is defined as a diseased condition which is caused by reduced blood flow in a coronary artery due to atherosclerosis & occlusion of an artery by an embolus or thrombus.
