Cardiac effects of anabolic steroid use amongst recreational body builders - a CMR study

Background Abuse of anabolic steroids to induce skeletal muscle hypertrophy is widespread amongst recreational bodybuilders, however, the cardiac effects of such drugs have not been systematically documented. The ability of cardiovascular magnetic resonance (CMR) to image the myocardium in any plane and achieve full myocardial coverage renders it the gold standard for assessing LV volumes and mass.We sought to investigate the cardiac effects of anabolic steroid use with CMR hypothesising that significant hypertrophy and distinct LV remodelling would be seen in steroid users relative to non-users.
