What causes myocardial?

What causes myocardial?

Causes of myocardial ischemia Myocardial ischemia occurs when blood flow to the heart muscle (myocardium) is obstructed by a partial or complete blockage of a coronary artery by a buildup of plaques (atherosclerosis). If the plaques rupture, you can have a heart attack (myocardial infarction).

What is meant by myocardial?

A heart attack, or myocardial infarction (MI), is permanent damage to the heart muscle. “Myo” means muscle, “cardial” refers to the heart, and “infarction” means death of tissue due to lack of blood supply.

Is myocardial a heart muscle?

Myocardial infarction (MI): The damaging or death of an area of the heart muscle (myocardium) resulting from a blocked blood supply to that area. It’s also the medical term for a heart attack. Coronary thrombosis: Formation of a clot in one of the arteries that supply blood to the heart muscle.

What is the main cause of a myocardial infarction?

The causes of myocardial infarction, or a heart attack, all involve some kind of blockage of one or more of the coronary arteries. The coronary arteries provide the heart with oxygenated blood, and if they become blocked, the heart will become oxygen starved, killing heart tissue and causing a heart attack.

• Blood thinners, such as aspirin, are often used to break up blood clots and improve blood flow through narrowed arteries.
• Thrombolytics are often used to dissolve clots.

Is myocardial infarction fatal?

It is too often deduced that myocardial infarction is due to coronary occlusion and that subsequent death needs no other explanation. But the great majority of myocardial infarctions are not fatal, whether treated or untreated.

Can you have a myocardial infarction and not know it?
