Not all heart attacks begin with the sudden, crushing chest pain that often is shown on TV or in the movies. In one study, for example, one-third of the patients who had heart attacks had no chest pain. These patients were more likely to be older, female, or diabetic. The warning signs and symptoms of a heart attack aren't the same for everyone. Many heart attacks start slowly as mild pain or discomfort. Some people don't have symptoms at all. Heart attacks that occur without any symptoms or very mild symptoms are called silent heart attacks.
Chest Pain or Discomfort The most common heart attack symptom is chest pain or discomfort. This includes new chest pain or discomfort or a change in the pattern of existing chest pain or discomfort.
Most heart attacks involve discomfort in the center or left side of the chest that often lasts for more than a few minutes or goes away and comes back. The discomfort can feel like uncomfortable pressure, squeezing, fullness, or pain. The feeling can be mild or severe.
Heart attack pain sometimes feels like indigestion or heartburn.
Chest pain or discomfort that doesn't go away or changes from its usual pattern (for example, occurs more often or while you're resting) can be a sign of a heart attack.
All chest pain should be checked by a doctor.
Other Common Signs and Symptoms Other common signs and symptoms of a heart attack include new onset of:
- Upper body discomfort in one or both arms, the back, neck, jaw, or upper part of the stomach
- Shortness of breath, which may occur with or before chest discomfort
- Nausea (feeling sick to your stomach), vomiting, light-headedness or sudden dizziness, or breaking out in a cold sweat
- Sleep problems, fatigue (tiredness), or lack of energy
Not everyone having a heart attack has typical symptoms. If you've already had a heart attack, your symptoms may not be the same for another one. However, some people may have a pattern of symptoms that recur.
The more signs and symptoms you have, the more likely it is that you're having a heart attack.
Act Fast The signs and symptoms of a heart attack can develop suddenly. However, they also can develop slowly—sometimes within hours, days, or weeks of a heart attack.
Know the warning signs of a heart attack so you can act fast to get treatment for yourself or someone else. The sooner you get emergency help, the less damage your heart will sustain.
Call 9–1–1 for help right away if you think you or someone else may be having a heart attack. You also should call for help if your chest pain doesn't go away as it usually does when you take medicine prescribed for angina.
Do not drive to the hospital or let someone else drive you. Call an ambulance so that medical personnel can begin life-saving treatment on the way to the emergency room.
