Heart attack symptoms
This picture shows the main symptoms of a heart attack. People who are having a heart attack often have only some of these symptoms. The pain, pressure, and discomfort caused by a heart attack mostly affect the left side of the body (shown in darker red) but can also affect the right. If you think you are having a heart attack, call 9-1-1 for an ambulance. Do not try to get yourself to the hospital.
