Abstract
Greater bone mineral density was observed after treating hypertension using angiotensin-converting enzyme inhibitor (ACEi). We report decreased rate of bone loss in hypertensive black men using ACEi for 9 years. There may be a gender- and race-specific effect of ACEi in the prevention of age-associated bone loss. PURPOSE: There is evidence of bone mass preservation in patients receiving ACEis, commonly used to treat hypertension. However, limitations of previous studies include being cross-sectional or only including a short-term follow-up of patients using ACEi and including patients with diabetes, which affects bone metabolism. None of the previous studies described effects of ACEi stratified by race. The objective of this study was to investigate differences in changes in bone mineral density (BMD) in older adults who suffer from hypertension and had reported ACEi use during each study visit for at least 9 years during the study, stratified by gender and race. METHODS: We used data from the Dynamics of Health, Aging and Body Composition (HABC) study, which enrolled 3075 community-dwelling older white and black individuals. We compared changes in femoral neck, total hip, and whole-body BMD after either no use of ACEi (n = 580) or long-term use (at least 9 years) of ACEi (n = 239) in HABC participants with hypertension and no known diagnosis of diabetes mellitus. RESULTS: Overall, BMD values significantly decreased for all subgroups over time. In the stratified multivariate analysis, long-term use of ACEi was associated with a reduced rate of decline for all three BMD measures among black men, but no significant effect was observed in the other subgroups. CONCLUSION: Our findings show a gender- and race-specific effect of ACEi in the prevention of age-associated bone loss that warrants further evaluation.
