Your emergency medical services may tell you how to help the person experiencing symptoms. Do exactly what the operator instructs. Call for help before doing anything else.  Calling 911 (or your emergency services number) will speed up your admittance into the hospital vs. driving to the emergency room yourself. Call an ambulance. Do not drive to the hospital yourself unless you have no other option available.    Treatment for heart attacks is most effective if started within 1 hour of the first appearance of symptoms. Sit down and rest. Try to keep calm by breathing evenly as best as you can. Loosen any tight clothing, such as shirt collars and belts. If you take prescription medication such as nitroglycerin, take your recommended dose while you wait for emergency services to arrive. Do not take prescription medication that has not been specifically prescribed for your use by a physician. Taking someone else's medication could harm you. Chewing and swallowing an aspirin can help break up the blood clot or blockage contributing to the heart attack. Do not take aspirin if you're allergic or have been told by your doctor not to take aspirin. Even if your symptoms improve within five minutes, see your doctor. A heart attack can leave clots in your bloodstream that can cause more health problems, such as a future heart attack or stroke. You need to be evaluated by a medical professional.
