Image from the CDC
Myocardial infarction (MI) (mi-0-KAR-dee-al) (in-FARK-shun) occurs when the blood flow to the heart is blocked.
A buildup of fat, cholesterol, and other substances, which form a plaque in the coronary arteries is the cause. When a plaque breaks away it can form a clot interrupting blood flow to the heart.
Damage or necrosis (death) of part of the heart muscle can occur. This condition is referred to as a heart attack or myocardial infarction.
