You may not feel all of these symptoms. Some people experience no symptoms -- this is called silent ischemia.
Women may have different symptoms of a heart attack than men. They may not experience chest pain but have other symptoms, such as pain high in the abdomen, jaw, back, or neck.
Call 911 Immediately About a Heart Attack if:
You or someone else shows signs of a heart attack. Seek emergency help right away, without delay.
Your angina (chest pain) no longer responds to medication. This may indicate that a heart attack is beginning.
Your angina attacks become more frequent, prolonged, and severe. As angina worsens the risk of heart attack increases.
Call Your Doctor About a Heart Attack if:
You are taking aspirin to prevent heart attack and your stool appears black and tarry. This may indicate gastrointestinal bleeding and could be a sign that aspirin has thinned your blood too much, problems that can and should be corrected.
