Vascular compliance during insulin infusion and oral glucose challenge

PWV increased during euglycemic clamp conditions without significant changes in C1 or C2. Oral glucose had less effect on PWV and changes in C1 and C2 were minimal. These data support mechanisms that link insulin and arterial stiffness in vascular physiology and suggest that part of the mechanism of CVD in insulin resistance may relate to insulin's effects on arterial stiffness.
