At the first signs of a heart attack, call for emergency treatment (911). Do not wait for your symptoms to “go away.” Early recognition and treatment of heart attack symptoms can reduce the risk of heart damage and allow treatment to be started immediately. Even if you’re not sure your symptoms are those of a heart attack, you should still be evaluated by a heart doctor.
The best time to treat a heart attack is within one hour of the onset of the first symptoms. When a heart attack occurs, there’s a limited amount of time before significant and long-lasting damage occurs to the heart muscle. If a large area of the heart is injured during the heart attack, full recovery becomes much more difficult.
Studies show that the people who have symptoms of a heart attack often delay, or wait to seek treatment, for longer than seven hours.
