My age is 52 yrs. In 2011, when I was 48 I underwent CABG wherein 6 graftings were done. Presently, I am taking Ecosprin 150mg. Atorvastatin 10mg. Telma 20 mg and Cardivas 3.125mg (twice daily). My concern is that I am losing muscle mass. My waist size has reduced from 34 inches to 32 inches I am losing flesh from legs, arms and hips. There has been no significant loss in weight which is more or less constant in all these four years. Every time I visit my cardiologist for follow up visit which is normally every six months, I raise this issue but he assures that there is no need of worry and this may be due to strict diet and morning walk. He assures that this loss of muscle mass will settle down on its own. I consulted other physicians also who also said that it is due to intake of statins. My LFT, Lipid Profile, BSF, BSPP, Thyroid Profile, Kidney profile reports are normal. I have seen so many people who underwent CABG but none of them have become so skinny. They look healthy as before. Please advise what could be reason for this. I would also like to mention here that this loss of muscle mass started much before I underwent CABG, may be from the age of 46 yrs.
