Heart Attack

A heart attack, also called a myocardial infarction, happens when a part of the heart muscle doesn’t get enough blood.
The accumulation of fat, cholesterol and other chemicals in the heart’s (coronary) arteries is typically what causes the obstruction. Plaques are the name given to the fatty, cholesterol-containing deposits. Atherosclerosis is the name for the process of plaque accumulation.
A plaque may occasionally burst and generate a clot that restricts blood flow. Part of the heart muscle can be harmed or destroyed by a lack of blood flow.
