Accuracy of One Minute Walking on Treadmill Exercise Test Using Automatic Measurements of Ankle-brachial Pressure Index

Abstract

Accuracy of one minute walking on treadmill exercise test (WT) using automatic measurements of ankle-brachial pressure index (ABI) is not known. Results of 5 and 1 minute WTs were compared with computed tomographic angiography findings in 57 patients who had suspected peripheral arterial occlusive disease (PAD). The sensitivity was 78.8% in both WTs. The specificity was 100% in 5 minute WT, and was 93.8% in 1 minute WT. Since the accuracy of 1 minute WT is almost equal with 5 minute WT, it is useful for a diagnosis of PAD.
