Myocardial infarction, another name for a heart attack, is an extremely serious condition caused by inadequate blood flow to your heart muscle. Although there are several potential causes, the most frequent one is a blockage in one or more of the arteries leading to your heart. Without blood supply, the damaged heart muscle will start to degenerate. If blood flow isn't quickly restored after a heart attack, there could be permanent cardiac damage and even death.
A heart attack is an emergency that puts your life in danger. If you think you or someone you're with is having a heart attack, dial 911 immediately (or your local emergency services phone number).
