We examined whether the A1166C polymorphism of the angiotensin II type I receptor gene (AGTR1) affects cardiovascular event occurrence in a Japanese prospective cohort study. The 2212 participants who gave informed consent for genetic analysis were enrolled in this study (the Shigaraki Study). The average observation period was 1954 days. Cardiovascular events occurred in 37 individuals (1.7%). The independent factors which specified cardiovascular events were age (hazard ratio (HR)=1.13; 95% confidence interval (CI): 1.10-1.16; p<0.0001) and sex (HR=2.18; 95%CI: 1.23-3.85; p=0.007). However, the A1166C polymorphism of AGTR1 was not a predictive factor for cardiovascular events (HR=1.11; 95%CI: 0.61-2.02; p=0.731).
