Figure 3 Effect of ischemia and reperfusion (IR) on endothelial and smooth muscle function. Flow-mediated dilation (FMD) was 8.7 ± 1.1% at baseline (BL) and was reduced by IR (a) (IR 4.9 ± 1.2%; *p < 0.001 vs. BL, analysis of variance; n = 13). Glyceryl trinitrate (GTN) dilation was 9.3 ± 2.0% at BL, and was unaffected by IR (b) (IR 10.0 ± 2.0%; p = NS, t test; n = 7).
