Heart Attacks

A heart attack occurs when blood supply to a portion of the myocardium is severely diminished or stopped. This occurs when the artery supplying blood to the myocardium is blocked by occlusion. This occlusion may be due to a condition known as atherosclerosis (accumulation of fatty substances along the arterial wall), thrombus or coronary vasospasm, and total occlusion. As part of the blood supply to the heart stops, that area of ​​the heart will no longer receive the oxygen or nutrients necessary to fulfill its function, and will die.

A heart attack is caused by an obstruction that prevents blood from flowing to the heart. A heart attack (or myocardial infarction) means death of myocardial tissue due to insufficient blood supply. Heart attacks can be understood as "circulation" problems. Heart attacks are very serious and sometimes even death

Myocardial infarction or heart attack means that a portion of myocardium died. When the blood supply to the myocardium is blocked, almost always a heart attack occurs. In most cases, a heart attack is an acute event caused by sudden rupture of atherosclerotic plaque in the coronary artery wall of a typical coronary artery disease (CAD) patient. However, there are other conditions that may cause myocardial infarction. In the majority of cases, heart attacks are caused by rupture or erosion of coronary plaque, which immediately leads to local thrombosis (thrombosis) in the arteries. Destruction of plaque formed by thrombus is called acute coronary syndrome or ACS.

Most heart attacks are the result of coronary artery disease (also known as atherosclerosis or "arteriosclerosis"). And it blocks the coronary fat and calcified plaque over time. A typical trigger for a heart attack is usually a thrombus that blocks blood through the coronary arteries. In the early 1980's, researchers blocked the stenotic blood flow due to the sudden formation of thrombus at the top of the plaque (such as scarring), but not nearly all of the ones that triggered a heart attack are the obstructive plaque itself Container This is called "plaque rupture". In contrast to previous observations, physicians now realize that plaques that are not so bad are the cause of most heart attacks.
