Role of Sympathetic Vasoconstriction on Insulin-Mediated Microvascular Recruitment and Glucose Uptake in Obesity (NCT03318094)
Vanderbilt University Medical Center
🔵 Active, Not Recruiting Phase1 💊 Investigational Drug / Biologic Sponsor: Vanderbilt University Medical Center
🩺 Plain-English Summary (8th-Grade Level)
The purpose of this study is to better understand the contribution of sympathetic vasoconstriction to impaired insulin-mediated vasodilation and subsequently insulin-mediated glucose uptake. The investigators will test the hypothesis that removal of sympathetic vasoconstriction can result in improvement in insulin-mediated vasodilation and subsequently sensitivity to insulin-mediated glucose uptake.
