Figure 1 Endothelium-dependent flow-mediated dilation (A) in diabetic (black bar) and control (white bar) subjects. FMD was significantly reduced in DM compared with control subjects (3.6 ± 0.6% vs. 7.1 ± 0.5%). Endothelium-independent GTN-induced vasodilation (B) was also reduced in DM compared with controls (15.4 ± 1.1% vs. 18.5 ± 0.8%), albeit to a lesser extent than FMD.
