I am a little confused by your description. IF your heart attack
was caused by a clot, then I would think it should have been considered. If you had a cardiac cath (dye test) that showed no obstruction, but you did have a confirmed heart attack (as opposed to chest pain
or angina- which can happen without muscle damage), I would wonder why.
If your cardiologist is good and you trust him/her, ask about it. Ask why you had the heart attack if you had no obstruction, and address your concern about the meds- Plavix
are very common meds which are used to help prevent further problems. Also, were you screened for cholesterol
and fractions? These are very important for management. You may need to be considered for treatment, but the cardiologist can help you understand.
