I am 52, I had chest pains a while back, so I had a full workup of my heart 8 years ago, angiogram, echocradiogram etc and everything was normal. The decision to proceed with the angiogram was what I remember was a change or irregularity in an EKG. Recently I had cardiac stress test that was abnormal so now a nuclear stress test was suggested. They base decisions on an EKG, so if I have a (short) history of problems with EKG, could this be a recurring problem when there is no cause for concern. I have closely monitored my health with regular physical exams and ony recently began treatment for HBP, which is now under control and cholestoral which was also recently diagnosed as borderline. Given my history I think I have been proactive in managing my health. My question is if I had a full workup that was normal 8 years ago and have been controlling my health is there cause for concern.
