Evidence suggests that the DD-genotype may be a risk factor for cardiac hypertrophy and heart failure, especially in hypertensive subjects. We assessed the relation between the ACE I/D polymorphism and the risk of incident heart failure in normotensive and hypertensive subjects. We investigated 4264 normotensive and 2174 hypertensive participants of the Rotterdam Study, a population based prospective cohort study. All subjects were available for followup from 1990 until 2000. Incidence rates(IR) of heart failure in normotensive subjects were the same over all genotype strata(10 per 1000 person-years). In hypertensive subjects, the IR increased with the number of D-alleles present (II:IR=13, ID: IR=18 and DD:IR=20 per 1000 person-years). Hypertensive subjects carrying the II-genotype did not have an increased risk of heart failure compared to normotensive II subjects. However, hypertensive subjects carrying one or two copies of the D-allele did have a significantly increased risk of heart failure(ID: RR: 1.4(1.1-1.9) and DD: RR: 1.5 (1.2-2.1)). Our findings suggest that the ACE I/D polymorphism may play a modifying role in the development of heart failure in hypertensive subjects.展开更多
