Signs and Symptoms of a Heart Attack
A heart attack is a medical emergency and prompt treatment increases the chance for survival. If you suspect that you or someone around you is experiencing a heart attack, seek medical attention immediately.
Symptoms of heart attack vary considerably, even in patients who have experienced a previous heart attack. Heart attack can occur suddenly and cause severe, intense symptoms; however, most begin slowly and cause mild discomfort that may come and go.
Signs of a heart attack include the following:
- Uncomfortable pressure, fullness, squeezing, or pain in the center of the chest that lasts more than a few minutes or that goes away and comes back.
- Pain or discomfort that radiates to other areas of the upper body (e.g., one or both arms, shoulders, back, neck, jaw, or stomach).
- Shortness of breath Often comes along with chest discomfort. But it also can occur before chest discomfort.
- Other symptoms include breaking out in a cold sweat, having nausea and vomiting, or feeling light-headed or dizzy.
