If you suspect you’re having a heart attack, there is no 10-second trick that can stop it. The most important action is to get emergency medical help immediately.
-
Call your local emergency service now. Don’t wait for symptoms to disappear.
-
Stop activity and sit or lie somewhere safe.
-
If you’re an alert adult with suspected heart-attack symptoms, chewing and swallowing aspirin (162–325 mg) may be appropriate if you are not allergic to aspirin and haven’t been told to avoid it. If you’re unsure, follow the emergency operator’s advice.
-
Do not drive yourself to the hospital.
-
If the person becomes unresponsive and isn’t breathing normally, start CPR and use an AED if available.
Possible heart-attack symptoms include chest pressure or pain, pain spreading to the arm, back, neck or jaw, shortness of breath, sweating, nausea, or lightheadedness.
If these symptoms are happening right now, call emergency services rather than trying a home remedy.
