Hi, I recently had a quadruple bypass, my symptoms were only angina, there were no heart attacks and the need for CABG was determined when I was undergoing an angioplasty. I m 66 years old, very active and fit, and my total cholesterol=164, HDL=48, LDL=101. My doctor has me on ATORVASTATIN 20 MG. With my cholesterol values which seem to be very good, is it really necessary to stay on the statin. My doctor said it s more for preventative of heart attacks in the future. Just would like another opinion.
