Comparative study of pressure (ankle-brachial pressure index) and flow (strain gauge plethysmography and reactive hyperaemia) measurements in diagnosis of peripheral arterial disease in patients with severe aortic stenosis.

Peak flow at 5 seconds is one of flow value that correlated well with ankle-brachial pressure index in detecting peripheral arterial disease in patients with and without aortic stenosis. Detection of peripheral arterial disease in patients with severe aortic stenosis seems to be less sensitive with flow measurements than with ankle-brachial pressure index.
