BACKGROUND AND OBJECTIVES: Ankle-brachial index (ABI) is currently recommended for the screening of @entity3657 . However, this method becomes less reliable in the presence of calcified, incompressible arteries, as they result in an erroneously elevated ABI, and an additional measure termed the @entity11438 ( @entity11438 ) is recommended. The evaluation of ABI, and in particular @entity11438 , typically requires significant technical skill and often involves referral to a vascular laboratory. This present situation reveals the need for a valid and reliable, automatic, noninvasive device that will provide both ABI and @entity11438 at the level of the primary care physician. The aim of this study was to evaluate the accuracy and reliability of such a device, the Vasera VS-1500AT, in the assessment of toe, ankle, and @entity551 . MATERIALS AND METHODS: This study involved the assessment of 80 limbs from 40 normotensive and @entity101 individuals (17 @entity1 and 23 @entity1 ) with a mean age of 45    18 years. RESULTS: There was a statistically significant correlation (r=0.92) between toe systolic blood pressures obtained manually with photoplethysmography compared with those obtained through the automated device. The same significant correlation was also seen between the two with ankle (r=0.87) and @entity551 . CONCLUSION: These strong correlations demonstrate that further investigation of this device is warranted regarding its use as a screening tool for the assessment of @entity3657 . The automation provided by this device could potentially eliminate variability in these measurements thereby allowing for screening and diagnosis to be done without referral to a vascular laboratory.
