GENERAL HISTOLOGY

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 too many heart muscle cells are damaged, the heart muscle becomes weakened. In some cases, this process happens very quickly and results in heart failure or even sudden death. More often, the heart tries to heal itself by changing the damaged or dead heart muscle cells into scar tissue.

Detailed explanation-3: -The most common cause is coronary artery disease or heart attack. However, it can also be caused by genetic changes. Hypertrophic cardiomyopathy. This type involves abnormal thickening of the heart muscle, which makes it harder for the heart to work.

Detailed explanation-4: -Once myocardium dies during a heart attack, it is replaced by scar tissue over the course of several weeks. The size, location, composition, structure and mechanical properties of the healing scar are all critical determinants of the fate of patients who survive the initial infarction.
