Insertion/deletion polymorphism of the ACE gene and adherence to ACE inhibitors

Abstract

AIMS: We investigated whether the insertion/deletion (I/D) polymorphism of the ACE gene modified the adherence to ACE inhibitors as measured by the discontinuation of an ACE inhibitor, or addition of another antihypertensive drug. METHODS: This was a cohort study among 239 subjects who started ACE inhibitor therapy. A Cox proportional hazard model was used to calculate relative risk (RR). RESULTS: During follow-up there was no significant difference between subjects with the DD, ID or II genotype (DD vs II; RR = 1.17, 95%CI: 0.78, 1.77 and ID vs II; RR = 1.06, 95%CI: 0.73, 1.55) in adherence. CONCLUSIONS: The I/D polymorphism of the ACE gene does not influence the adherence to ACE inhibitors.
