I think you should be concerned that your doctor(S) didn't explain and evaluate... prognosticate.
Sounds like you have some problems, but I can't give a specific diagnosis. The angiogram sounds strange, did you undergo a nuclear stress test and that indicated possible blockage?
Ask/demand your doctor put it all together with a forecast on you future health.
I have to agree, I would want more info on why they want an angiogram. While it may be necessary, I would ask for a better explanation.
I have an Adrenal Tumor and the Endocrinologist sent me to the Cardiac Dr. since I have experienced chest pain she wanted to know if I could withstand surgery. I had a Nuclear Test,Echocardiogram,Chemical Stress Test.
I have High Blood Presure,High Cholesterol,Obesity, Pre Diabetes and a former smoker although it has been15 years smoke free.He said it showed a possible blockage and small hole a Patent Foramen Ovale. They did not think they would get any good pictures off a CT Scan. He said it was better to be safe then sorry. I want to know if these sound like bad problems with my heart?
