Figure 3 (A) Flow-mediated dilation (FMD) (percent change in diameter at 1 min after cuff release) is linearly proportional to systolic wall shear stress during peak hyperemia (WSS_hyp, systolic wall shear stress immediately after cuff release). FMD = 2.9 (WSS_hyp) – 1.1. (B) FMD is also linearly proportional to the change in systolic wall shear stress (WSS, change from baseline to peak hyperemia immediately after cuff release). FMD = 2.5 (WSS) + 5.0.
