I, too, had a heart attack about 20 years ago. The only symptoms I had was a bad case of heart burn that I couldn't get rid off & being really irritated. My DH saved my life that night cause he said my color wasn't good. He made me go get checked at 1:30 AM & they said I had already had a heart attack the day before (no symptoms at all the day before) & was in the middle of another one then. They told him if he had waited till morning to bring me in, he would have found me dead. I thought the Drs were nuts. They were not able to do a by pass on me as that was the part that was damaged. So have just had to live with limitations.
