Chest pain or pressure, or a strange feeling in the chest.
Shortness of breath.
Nausea or vomiting.
Pain, pressure, or a strange feeling in the back, neck, jaw, or upper belly, or in one or both shoulders or arms.
Light-headedness or sudden weakness.
A fast or irregular heartbeat.
The more of these symptoms you have, the more likely it is that you're having a heart attack. Chest pain or pressure is the most common symptom, but some people, especially women, may not notice it as much as other symptoms. You may not have chest pain at all but instead have shortness of breath, nausea, or a strange feeling in your chest or other areas.
If you have symptoms of a heart attack, call 911 or other emergency services immediately. After you call 911, the operator may tell you to chew 1 adult-strength or 2 to 4 low-dose aspirin. Wait for an ambulance. Do not try to drive yourself.
