Some heart attacks are sudden and intense, causing someone to gasp dramatically, clutch her heart and drop to the ground. No one has any doubts about what's happening. But most heart attacks start slowly, with mild pain or discomfort. Often the people affected aren't sure what's wrong and wait too long before getting help.
Here are some signs a heart attack may be 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. This feeling may occur with or without chest discomfort.
- Other signs of discomfort. These may include breaking out in a cold sweat, nausea or lightheadedness.
- As with men, women's most common heart attack symptom is chest pain or discomfort. But women are somewhat more likely than men to experience some of the other common symptoms, particularly shortness of breath, nausea/vomiting and back or jaw pain.
If you or someone you are with has chest discomfort, especially with one or more of the other signs, don't wait longer than five minutes before calling 9-1-1 for help."
