Cardiac stress test accuracy

[sferias]

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.

Two years ago after having a stent fitted, it was known my LAD was 100% blocked and
my RCA was heavily diseased. I lasted 30 mins on the treadmill which they said was
extremelly good, but no problems were showing up. Even though I endured a lot of discomfort and knowing my arteries are such a mess, it still would have classified me
as fit/normal. So I'll let you be the judge.

The cardiac stress test trumps the EKG in my opinion.  What abnormality did the stress test show?
I've had negative changes in my cardiac condition just weeks from tests and procedures, and eight years is a long time.  Without knowing what the abnormality in the stress test indicated, it's difficult to suggest anything, however.
