Hi, I am 37 year old male with no major problems. Recently in two regular helath checkups over 2-3 years, my TMT came positive both the times and the doctor recommended angiography. I doubt if it is really needed, as I can easily walk(brisk) for 45 minutes, climb stairs etc. and have never felt any discomfort during exercises. Also, all other blood tests are normal like trigycerides, cholestrol etc.My question is do I need to take it seriously?
