It is reasonable to assume if something serious was found wrong you'd get a call. That said, I have an experience of nuclear stress giving false positive on blockage. I have never had any blockage as measured by the invasive angiogram.
I always ask for a printout of test results and muss over them, and sometimes call my doctor to discuss. I have never caught an error or omission - but that is really the doctor's responsibility, I am not qualified to do more than ask questions.
Yep, but be proactive. The card is busy and scheduling people are notoriously bad for missing stuff. You might as well call today for your appointment...
