I had a heart attack a little over a year ago. Had a stent in one artery. I take Plavix, Diovan, Metoporol, Crestor and Zetia as well as CoQ10, Omega 3 fish oil, vitamin D3, and a multi vitamin. I also have a vertebrae in my lower back that is out of place and makes excersize and walking painful. I try to be as active as possible. Could my medications be causing me to gain weight?
