Abstract:
BACKGROUND: Contemporary guidelines recommend angiotensin-converting-enzyme inhibitors (ACEi) or angiotensin-receptor blockers (ARB) for hypertensive patients with diabetes. However, there is limited data to evaluate the comparison between ACEi and ARB on end stage renal disease (ESRD) and major adverse cardiovascular events (MACE), in Asian diabetic patients. METHODS: We used the Taiwan Longitudinal Cohort of Diabetes Patients Database to perform a population-based dynamic cohort study. The comparison between ACEi and ARB on ESRD and MACE in diabetic patients was examined using the propensity score weighting method. We followed these patients until the occurrence of first study outcomes or end date of the study, whichever came first. RESULTS: There were 6898 and 12,758 patients in ACEi and ARB groups, respectively. The mean follow-up period was about 3.5 years in ESRD and 2.5 years in MACE. The incidence of ESRD was 0.44 % and 0.63 % per person-years in the ACEi and ARB group, respectively. The risk of ESRD was lower in the ACEi group than the ARB group [hazard ratio (HR) 0.69; 95 % confidence interval (CI) 0.54-0.88, P = 0.0025]. Among those without chronic kidney disease (CKD), the incidence of ESRD was 0.30 % and 0.37 % per person-years in the ACEi and ARB group, respectively. ACEi was similar to ARB in preventing ESRD for those without CKD (P = 0.11). Among those with CKD, the incidence of ESRD was 1.39 % and 2.34 % per person-years in the ACEi and ARB group, respectively. The ACEi group had a lower risk of ESRD than the ARB group (HR 0.61; 95 % CI 0.42-0.88, P = 0.008). The incidence of MACE was 9.33 % and 9.62 % per person-years in the ACEi and ARB group, respectively. There was no significant difference in the composite MACE outcome between the two groups (P = 0.42), but the ACEi group was associated with a higher risk of stroke than the ARB group (HR 1.12; 95 % CI 1.02-1.24, P = 0.02). CONCLUSIONS: ACEi compared with ARB was associated with a lower incidence of ESRD, especially in those with CKD. Though ACEi and ARB had a similar risk of composite MACE outcome, ACEi had a slightly higher incidence of stroke than ARB, among the Asian diabetic patients.
