What Is a Heart Attack?

A heart attack, also known as acute myocardial infarction (AMI), is an urgent message from your heart that it’s starved for oxygen. When a clot blocks a heart vessel, oxygen-rich blood can’t reach your heart. As a result, heart muscle begins to die and symptoms of a heart attack begin.

Heart disease is the leading cause of death in men and women. Learn the symptoms of a heart attack so you are better prepared to act in an emergency. Quick access to medical care can minimize damage to the heart muscle and improve the outcome.
