Flow-mediated dilatation of the brachial artery was evaluated after reactive hyperemia induced by cuff obstruction of the forearm, using high-resolution ultasonography.
The hyperemic response was measured as the percent change from baseline to the point of maximal reactive hyperemia following release of the forearm cuff occlusion.
High-density lipoprotein cholesterol levels, baseline brachial artery diameter, baseline blood flow and the increase in the blood flow during the reactive hyperemia were also similar.
