Myocardial infarction, also known as a "Heart Attack," occurs when a portion of the heart muscle receives insufficient blood. The longer the heart muscle goes without treatment to restore blood flow, the more damage occurs. Coronary artery disease (CAD) is the most common cause of myocardial infarction. A less common cause is a severe spasm or sudden contraction of a coronary artery, which can cut blood flow to the heart muscle. It is critical to recognize that not everyone suffers from severe chest pain; this is particularly true for many women. This same chest pain is quite often misdiagnosed as indigestion.
The most commonly observed symptoms of Myocardial infarction are:
The leading causes of having a Myocardial infarction are:
CHD is a disorder in which cholesterol deposits known as plaques obstruct the major arteries supplying the heart with blood. Before a heart attack, one of the plaques breaks or ruptures, causing a blood clot to develop at the rupture site. A heart attack could occur if the clot obstructs blood flow to the heart.
Completely or partially occluded coronary arteries may cause heart attacks. An ST-elevation myocardial infarction (STEMI) is indicated by a total blockage. A partial blockage, on the other hand, suggests that you had a non-ST elevation myocardial infarction (NSTEMI).
Another cause of a heart attack is a spasm or contraction of a coronary artery, which cuts off blood supply to a segment of the heart muscle. Drugs like cocaine and cigarettes can produce a fatal spasm.
The most effective way to avoid a Myocardial infarction is to make lifestyle changes. There are three vital steps you can take to help prevent a heart attack or stroke are:
