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: -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-3: -Heart Attack (Myocardial Infarction) 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-4: -Cell Death in myocardial infarction In this section, we focus on cardiac myocyte death in the ischemic zone. During myocardial infarction, cardiac myocytes in the ischemic zone die by both apoptosis and necrosis.

Detailed explanation-5: -If too much muscle dies, the heart is not able to pump enough blood to the rest of the body. Damage to the heart cells that regulate the heartbeat may cause fatal heart rhythm problems. Sometimes, the heart muscle weakens and can tear as a result of the damage. This causes a fatal hemorrhage (bleeding).
