[Ankle-brachial index to detect peripheral arterial disease: concordance and validation study between Doppler and an oscillometric device].

Background And Objective: To evaluate the sensitivity and specificity of ankle-brachial index (ABI) determined by oscillometry, using a Doppler ultrasound probe as a gold standard. We also aimed to evaluate the agreement between both methods.

Patients And Method: Right and left ABI measurements (ABIr,ABIl) with oscillometric (OMRON-705-CP) and Doppler (DIADOP-50) devices in hypertensive patients without peripheral arterial disease.
