Figure 3 The Effect of DM on the Vasoconstrictions of RA Grafts in Response to High K+ and the Vasorelaxations in Response to CCh

(A) There was no difference in radial artery (RA) contractions in response to high K+ between patients with diabetes mellitus (DM) and nondiabetic patients (p = NS). Values are expressed as median (25th to 75th percentile) and range. (B) The RA from patients with DM had lower relaxations in response to carbachol (CCh) (10^–4 mol/l) compared with nondiabetic patients. Values are expressed as mean ± SEM.
