The association between renin angiotensin aldosterone system blockers and future osteoporotic fractures in a hypertensive population – A population-based cohort study in Taiwan

Research output: Contribution to journalArticle

Abstract

Some cohort studies showed the possibility of renin-angiotensin-aldosterone system (RAAS) blockade in preventing future osteoporotic fractures. The study aimed to evaluate the association between angiotensin converting enzyme inhibitors (ACEIs), angiotensin II receptor blockers (ARBs), and future osteoporotic fracture in a hypertensive population. We queried the Taiwan Longitudinal Health Insurance Database between 2001 and 2012. We used propensity score matching and the total cohort was made up of 57,470 participants (28,735 matched-pairs using or not using RAAS blockers). The mean follow-up period was 6 years. The number of incident fractures was 3757. Hazard ratios (HRs) [95% confidence interval (CI)] of ACEIs and ARBs use with incident fractures were calculated. The incidence of future osteoporotic fracture was significantly lower in the ACEI and ARB user groups but not in the group using an ACEI plus ARB concomitantly, when compared with RAAS blocker nonusers. Comparing ACEI users with RAAS blocker non-users and ARB users with RAAS blocker non-users, the HRs for composite fractures were 0.70 (0.62–0.79) and 0.58 (0.51–0.65), respectively. Sensitivity analysis confirmed a lower incidence of future osteoporotic fracture in patients taking an ACEI for >55 cumulative defined daily doses (cDDDs) and those who received an ARB for >90 cDDDs. These results suggested a lower incidence of future osteoporotic fracture in a hypertensive population who were using an ACEI or ARB compared with RAAS blocker nonusers but not in the group taking an ACEI and ARB concomitantly.
