Warning Signs of a Heart Attack

The National Heart Attack Alert Program notes these major symptoms of a heart attack:

• Chest discomfort. Most heart attacks involve discomfort in the center of the chest that lasts for more than a few minutes, or goes away and comes back. The discomfort can feel like uncomfortable pressure, squeezing, fullness, or pain.
• Discomfort in other areas of the upper body. This can include pain or discomfort in one or both arms, the back, neck, jaw, or stomach.
• Shortness of breath. This often comes along with chest discomfort. But it also can occur before chest discomfort.
• Other symptoms. These may include breaking out in a cold sweat or feeling nausea or light–headedness.
  If you think that you or someone you know is having a heart attack, you should call 9–1–1 immediately.
