MICROANATOMY

Detailed explanation-1: -Most myocardial infarctions are due to underlying coronary artery disease, the leading cause of death in the United States. With coronary artery occlusion, the myocardium is deprived of oxygen. Prolonged deprivation of oxygen supply to the myocardium can lead to myocardial cell death and necrosis.

Detailed explanation-2: -A heart attack (medically known as a myocardial infarction) is a deadly medical emergency where your heart muscle begins to die because it isn’t getting enough blood flow. A blockage in the arteries that supply blood to your heart usually causes this.

Detailed explanation-3: -A heart attack, or myocardial infarction, is a medical emergency in which the supply of blood to the heart is suddenly and severely reduced or cut off, causing the muscle to die from lack of oxygen.
