ON ANGIOGRAM I WAS DIAGNOSED HAVING 80% BLOCK IN CAD CORONARY ARTERHY about a month back.BUT I AM VERY NORMAL AND NOT NOTICING ANY PAIN OR BREATHING PROBLEM .I AM REGULARLY GOING FOR BRISK WALKING FOR ONE HOUR AND CLIMBING THREE FLOORS THREE TIMES A DAY.I am regularly taking the following tablets for the last one year.
1.METOPROLOL 25MG XL;AMLODIPINE2.5mg;NITOGLYCERINE GTN 2.6 sorbitrate twice;TELMISARTAN-20.;ECOSPIRIN 75;
ROSUVASTATIN 5MG ;FENOFIBRATE160MG
Whether CABG /STENT placement is necessary since I am doing all normal activities without any symptoms or strain?
