Role of Angiotensin II in Insulin-induced Microvascular Activity

Not Applicable
Completed
Conditions
Insulin Sensitivity
Microcirculation
Interventions
Registration Number
NCT01024543
Lead Sponsor
Maastricht University Medical Center
Brief Summary

In this study we hypothesize infusion of Angiotensin II improves the insulin-induced microvascular dilatation and therefore insulin-mediated glucose uptake. Objectives: Does infusion of Angiotensin II increase insulin-mediated glucose uptake via enhanced insulin-mediated microvascular function in healthy subjects?
