STRETCH Study: Effect of Distensibility on Endothelial-Dependent Vasoreactivity in Patients With ISH

Summary

Determine whether increasing arterial distensibility by decreasing advanced glycation end-product (AGE) cross-link components of vascular stiffness improves (a) endothelial-mediated vasoreactivity at rest, as assessed by flow-mediated vasodilation (FMD), and (b) endothelial-mediated vasoreactivity after exercise, as assessed by pulse perfusion-mediated vasodilation (PPMV).
