[Ankle-brachial pressure index as a predictor of future cardiovascular outcomes].

Peripheral arterial occlusive disease is very common in the general population and it is mostly of atherosclerotic origin. About 50%-75% of patients are asymptomatic. Many studies have shown the ankle-brachial pressure index (ABPI) to be a simple and reliable test with high sensitivity (90%) and specificity (98%) in the diagnosis of hemodynamically relevant stenosis of an arterial segment and also in detection of asymptomatic patients.
