If you suspect a heart attack, there is no safe home method to “stop” it. Treat it as an emergency:
- Call your local emergency medical service immediately and do not drive yourself.
- Keep the person resting and follow the emergency operator’s instructions. For an alert adult with non-traumatic chest pain, aspirin may be recommended while waiting, but only if there is no aspirin allergy or medical advice against it.
- If the person becomes unresponsive and is not breathing normally, start CPR and use an AED if available.
