I just had symptoms of a heart attack upper abdominal pain (almost chest pain) up through my neck, jaw and teeth. I have been diagnosed with mild heart disease, but have never experienced this pain so prominently before. I took an aspirin and sat down and it is subsiding. If it totally subsides, what should I do. I have an appointment with a cardiologist in about a month for my first appointment. I'm 5'7" and 140 lbs. , but have been under tremendous stress. I have significant plaque build up in my Aorta and will be getting advice on that in a month.
