| Abstract: | This study investigated bone mineral and body composition changes after coronary artery bypass grafting (CABG) in men. Twenty-six men 50 to 79 years of age underwent CABG for multivessel coronary disease. Dual-energy x-ray absorptiometry was performed before surgery and 3 months and 1 year after treatment to assess bone mineral content (BMC), bone mineral density (BMD), and body composition. Through 3 months after treatment, BMD decreased at the total body, arms, and pelvis. BMC of the arm decreased and losses at the total body and legs approached significance. Fat-free mass decreased in the arms and total body but not in the legs. Neither total body nor regional fat mass changed. At the 1-year follow-up visit, 15 of the initial 26 subjects returned for dual-energy x-ray absorptiometry. Compared with before treatment, BMD decreased at the total body and legs, whereas losses at the arms approached significance. Arm BMC decreased over the 1-year post-treatment period. No changes were observed in body composition. In conclusion, CABG and the ensuing convalescence period results in considerable arm bone mineral losses through 1 year after treatment. |
