Also known as: Myocardial Infarction, MI, Cardiac Arrest
A heart attack occurs when blood flow to part of the heart muscle is blocked, usually by a blood clot forming in a coronary artery narrowed by plaque buildup. Without quick restoration of blood flow, the heart muscle begins to die within minutes. Survival rates have improved dramatically with early treatment, but it remains a leading cause of death worldwide.
