Thanks for writing in.
I am a qualified and certified cardiologist. I read your mail with diligence.
When you were referred for the treadmill test there must have been suspicion of coronary artery
disease. Due to baseline problem, the doctor is unable to interpret report. Some changes would have been there before you were sent for test other wise why the test was advised? The specificity of treadmill test is about 75% meaning if it is positive then you have that much chances of having a disease. The situation has not changed. If the first doctor was almost sure of coronary artery disease, he/she would have advised you a coronary angiography
which is almost 100% specific. Radionuclide
scan is about 75% to 80% specific, so here one test is being substituted for other. I see no cause for worry. You are only a suspect not a patient of coronary artery disease. Good Luck.
With Best Wishes
