ANATOMY

Detailed explanation-1: -Myocardial infarction (MI): It occurs when an area of the heart muscle (myocardium) is damaged or dies after blood supply is blocked. It’s the classic medical term for a heart attack.

Detailed explanation-2: -If the blood and oxygen supply is cut off, muscle cells of the heart begin to suffer damage and start to die. Irreversible damage begins within 30 minutes of blockage. The result is heart muscle affected by the lack of oxygen no longer works as it should.

Detailed explanation-3: -During a heart attack, a lack of blood flow causes the tissue in the heart muscle to die. A heart attack occurs when the flow of blood to the heart is severely reduced or blocked. The blockage is usually due to a buildup of fat, cholesterol and other substances in the heart (coronary) arteries.

Detailed explanation-4: -Cardiomyopathy (kahr-dee-o-my-OP-uh-thee) is a disease of the heart muscle that makes it harder for the heart to pump blood to the rest of the body. Cardiomyopathy can lead to heart failure. The main types of cardiomyopathy include dilated, hypertrophic and restrictive cardiomyopathy.
