I heard a few stories of people having bad stomach pains just prior or during a heart attack. This also happened to my father. He almost decided not to call the ambulance but my brother called for him. Thank God he called because he was suffering heart failure.
Yeah, just happened to a 39 year old guy at work recently. Eating lunch, felt sick to his stomach and left his friends to go to the bathroom. Unfortunately, no one followed him in and it was a bathroom not often used. Someone found him dead an hour later from a heart attack. Tragic.
