A heart attack, also known as a myocardial infarction, occurs when an area of heart muscle dies or is permanently damaged due to an inadequate supply of oxygen to that area.
Most heart attacks involve discomfort in the center of the chest that lasts more than a few minutes, or that goes away and comes back. It can feel like uncomfortable pressure, squeezing, fullness or pain.
Discomfort in other areas of the upper body
Symptoms can include pain or discomfort in one or both arms, the back, neck, jaw, or stomach.
Shortness of breath
May occur with or without chest discomfort.
These may include breaking out in a cold sweat, nausea, or lightheadedness.
If you or someone you're with has chest discomfort, especially with one or more of the other signs, don't wait longer than a few minutes (no more than 5) before calling for help. Call 911 or your emergency response number. Get to a hospital right away.
