About every 40 seconds, someone in America has a heart attack. A heart attack is an urgent message that your heart needs oxygen. The most common cause is coronary artery disease. When a blockage or plaque within a coronary artery ruptures or breaks, a blood clot forms around it. This blood clot can block the oxygen-rich blood from getting to the muscle of your heart. That causes the heart muscle to start dying, and you begin to feel the symptoms of a heart attack. Your doctor may also refer to this as, “acute myocardial infarction."
Don’t wait to get help if you have any heart attack warning signs. Some heart attacks are sudden and intense. Others start slowly with mild pain or discomfort. Pay attention to your body and call 911 if you have:
- Chest discomfort. Most people having a heart attack feel discomfort in the center of the chest. It can last more than a few minutes, or it may go away and then return. 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 the:
- Arms (one or both)
