Background The present study aimed to investigate the association between low bone mass (LBM) and coronary artery disease (CAD) in male patients. Method and Results The data for 47 men who were screened for osteopenia and osteoporosis with dual energy X-ray absorptiometry and then underwent coronary angiography between February 2005 and May 2006 were retrospectively analyzed. Bone mineral density of the femur neck was stratified as normal (T score >-1.0 SD) or low (T score <-1.0 SD) and CAD was defined as ⪈50% occlusion in at least 1 major coronary artery. Thirty-two patients were found to have angiographically significant CAD. Patients in the LBM group had a significantly higher incidence of CAD. Low bone mass was significantly and positively correlated with the Gensini scores of the patients (r=0.6037, p<0.0001) and was found to be an independent predictor of CAD in multivariate logistic regression analysis (odds ratio: 5.4 [95%confidence interval 1.66 and 17.49]; p=0.0049). Repeated statistical analyses with the acceptance of CAD as coronary artery stenosis >75% confirmed the same results. Conclusion Low bone mass was significantly associated with angiographically documented CAD in males.
