Objective To evaluate the feasibility of detecting peripheral artery disease (PAD) using ankle-brachial index (ABI) determined by an electronic sphygmomanometer in patients with type 2 diabetes mellitus (DM). Method The brachial blood pressure and the ankle blood pressure were measured in each upper limbs and lower limbs by the Doppler ultrasound method and the electronic sphygmomanometer method in fifty-nine DM patients who were selected from Department of Geriatric Endocrinology of General Hospital of PLA. ABI was calculated with the formula of ABI = ankle systolic blood pressure/ brachial systolic blood pressure. The measurement data were expressed as x?s. Then the data of systolic pressure and ABI were analyzed by paired Student's t tests and correlations. The related diagnosis criteria of PAD, such as sensitivity, specificity, positive predictive value, negative predictive value, and the global accuracy were calculated. Furthermore, the correlation of brachial blood pressure as measured by the electronic sphygmomanometer and the mercury column sphygmomanometer was compared. Results There were no significant differences but good correlations between the data of systolic pressures and ABI obtained as measured by two methods. The correlation for systolic pressure was right upper limbs 0.92, P
