A heart attack or acute myocardial infarction (MI) occurs when one of the arteries that supplies the heart muscle becomes blocked. Blockage may be caused by spasm of the artery or by atherosclerosis with acute clot formation.

Congratulations to Dr. Mehran Moussavian for being in the top 90th percentile at Sharp, and in the nation for the treatment of myocardial infarction (MI).
