Definition

Noun: 1. A sudden and severe medical emergency involving the heart: A heart attack is a condition where the blood supply to a part of the heart muscle is suddenly blocked, usually by a blood clot. This blockage prevents that part of the heart from getting oxygen, which can damage or destroy the heart tissue. 2.
