<b><i>Aim</i></b>: Peripheral artery disease (PAD), defined as a decreased ankle brachial index (ABI), is a risk factor for cardiovascular disease; however, few studies have assessed the relationship between a low ABI and cardiovascular risks in Asian populations. We herein examined the relationship between the ABI and the development of cardiovascular disease in a Japanese community.<br><b><i>Methods</i></b>: A total of 2,954community-dwelling Japanese individuals without prior cardiovascular disease ≥ 40years of age were followed up for an average of 7.1years. The subjects' ABIs were categorized into the three groups: low (≤0.90), borderline (0.91-0.99) and normal (1.00-1.40). We estimated the relationship between the ABI and cardiovascular risk using a Cox proportional hazards model.<br><b><i>Results</i></b>: During the follow-up period, 134subjects experienced cardiovascular events. The incidence of cardiovascular disease across the ABI values was significantly different (<i>p</i><0.001). After adjusting for confounding factors, namely age, sex, systolic blood pressure, use of anti-hypertensive drugs, diabetes, total cholesterol, high-density lipoprotein cholesterol, obesity, smoking, alcohol intake and regular exercise, individuals with a low ABI were at 2.40-fold (95% confidence interval [CI] 1.14-5.06) greater risk of cardiovascular disease and 4.13-fold (95% CI 1.62-10.55) greater risk of coronary heart disease.<br><b><i>Conclusions</i></b>: Our findings suggest that individuals with an ABI of ≤ 0.90 have an increased risk of cardiovascular events, independent from traditional risk factors, in the general Japanese population.
