Stress Test Results

[Mickey56]

I had a tread mill stress test and a nuclear stress test.  Briefly, the results were: 1) reached 100% target heart rate, no chest pains, no arrhythmia 2) LVEF is 56% 3) moderate size inferior ischemia 4) ECG is positive for ischemia at a good workload (143 heart rate).
I have formed a preliminary impression from my research on the Internet, but would appreciate feedback on the above 4 items.  I havel scheduled a heart catherterization.
Thank you.

You are in very good condition, and it appears all is well except for the positive ECG.  I'm curious why you had both tests?  It is possible to have a vessel lesion without any symptoms but unusual...are you diabetic? I never had any chest pain or warning regarding my CAD until I had a silent heart attack causing congested heart failure 5 1/2 years ago.

Thank you for your comments.  Yes, I am diabetic type 2 with fairly good control through nutrition and exercise, but it is a difficult process, as you know.  I typically have a quarterly physical examination, of my own choosing.  
Last week, I asked my doctor that I wanted to ease my regimens and broaden my nutrition a bit more and requesed basal insulin, which I just started.  Also, in that examination, I requested a stress test, and I think that my doctor felt that I may not cope with the tread mill test, so he included the nuclear stress test.  I felt that I handled the tread mill fine, and I felt that the nuclear stress test would be prudent.
I am 76 years old, 5'10", 177 lbs., 120/70, LDL 70, glucose typically in the 140 range.  I am interested in medical technologies, because I am a former VP in a medical care company, and thus my question.  Again, thanks.
