Most heart attacks involve discomfort in the center or left side of the chest. The discomfort usually lasts for more than a few minutes or goes away and comes back. It can feel like pressure, squeezing, fullness or pain. It also can feel like heartburn or indigestion. The feeling can be mild or severe.
Upper body discomfort.
You may feel pain or discomfort in one or both arms, the back, shoulders, neck, jaw or upper part of the stomach (above the belly button).
Shortness of breath.
This may be your only symptom, or it may occur before or along with chest pain or discomfort. It can occur when you are resting or doing a little bit of physical activity. It’s important to note that some people can have few symptoms and be unaware that they’ve had a heart attack. People who have diabetes may have no symptoms or very mild ones and women are more likely to have shortness of breath, nausea and vomiting, unusual tiredness (sometimes for days), and pain in the back, shoulders and jaw.
Call 911 immediately if you or a loved one may be experiencing a heart attack.
