PATHOLOGY

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: -Coronary heart disease This is caused when the heart’s blood vessels-the coronary arteries-become narrowed or blocked and can’t supply enough blood to the heart. It can lead to angina and/or a heart attack.

Detailed explanation-3: -The blood clot is the actual cause of the heart attack. 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-4: -A heart attack happens when one or more areas of the heart muscle don’t get enough oxygen. This happens when blood flow to the heart muscle is narrowed or blocked. This causes areas of the heart muscle to become damaged or die (infarct). A blood clot is the usual cause of a heart attack.
