**What is Myocardial Infarction?**
**Question: What is Myocardial Infarction?**
**Answer:**
Myocardial infarction, commonly known as a heart attack, occurs when there is an abrupt blockage of blood flow to a portion of the heart muscle. This blockage deprives the heart tissue of oxygen and nutrients, leading to damage or death of the affected cells. Myocardial infarctions are often caused by the buildup of atherosclerotic plaque in the coronary arteries, the blood vessels that supply the heart with blood.
