Some heart attacks are sudden and intense but most start slowly, with mild pain or discomfort. Here are signs that can mean a heart attack is happening:
- Chest discomfort. 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 with or without chest discomfort.
- Other signs may include breaking out in a cold sweat, nausea or lightheadedness.
If you experience any of these heart attack symptoms, immediately call 9-1-1.
