Myocardial infarction Heart attack Biology essay
Myocardial infarction MI, also called heart attack, is a myocardial injury caused by myocardial ischemia. the fourth Universal Definition of Myocardial Infarction emphasized the difference between acute myocardial infarction AMI and myocardial injury and divided MI into five types, 2, 3. Myocardial infarction MI is commonly referred to as a “heart attack.” Myocardial ischemia is an inadequate perfusion to the myocardium resulting from a partial or complete blockage of blood and oxygen to the heart. The leading cause of heart attack is coronary artery disease. In an emergency, when the cells lose oxygen, ischemia, myocardial infarction MI, colloquially known as 'heart attack', is caused by reduced or complete cessation of blood supply to part of the myocardium. Myocardial infarction can be 'silent' and go unnoticed, or it can be a catastrophic event leading to hemodynamic deterioration and sudden death. Most myocardial, myocardial infarction. A myocardial infarction, also called a heart attack, is a disease that affects many organs in our body, these organs are the heart, coronary arteries and lungs. As we know, our heart has four main arteries and two of them are large, branching coronary arteries that supply oxygen-rich blood to the muscles of the coronary arteries. Cardiac troponin T and I isoforms cTnT and cTnI are expressed in myocardial tissue and are by far the most specific and sensitive indicators for the diagnosis of acute myocardial infarction AMI. 1- are only a few studies that have reported the expression of cTnT and cTnI outside the myocardium, especially,
