question: Hello doctor,I am 43 years old with PVC and PAC's. Very mildly elevated cholesterol. I had a treadmill test and it said borderline ST segment changes. So, my cardiologist had me do a treadmill with echo (I do not have the results yet). My question is if I get back the treadmill with echo results and everything is normal, can I stop worrying? I have had a coronary calcium score test. Currently, I am taking testosterone replacement and supplements (Magnesium, Zinc, Probiotics, Vitamin D, and Fish oil).
