OBJECTIVE: To describe the distribution of ankle-brachial index (ABI) among Japanese cardiovascular inpatients and to explore risk factors of peripheral arterial disease (PAD) associated with ABI ≤0.9. MATERIALS AND METHODS: This study was a retrospective analysis using clinical record databases of patients with cardiovascular disease admitted to the Department of Cardiovascular Medicine, Kumamoto University Hospital between 2007 and 2014. RESULTS: Of 3639 patients included in the analysis, male patients accounted for 62.1% and the mean age of patients was 66.1 years. Ischemic heart disease (IHD) was observed in 49.1%. ABI ≤0.9 was observed in 11.3% of all patients, 14.1% in the IHD group and 8.5% in the non-IHD group. Age of ≥65 years (odds ratio [OR]: 2.93, 95% confidence interval [CI]: 2.22-3.86), current smoking (OR: 2.28, 95%CI:1.71-3.04), diabetes (OR: 2.15, 95%CI:1.71-2.71), hypertension (OR: 1.42, 95%CI:1.12-1.81) and chronic kidney disease (OR: 2.52, 95%CI:1.82-3.48) were significantly associated factors with ABI ≤0.9. CONCLUSIONS: This study suggests that PAD is prevalent even in patients without IHD. Active management of risk factors, early detection of PAD based on ABI, and therapeutic intervention could be effective in preventing future cardiovascular events or death.
