Characterization of Brachial Arterial t-PA Release, Endothelial Function, Obesity and Inflammation (P1A3B)
Recruitment status was Recruiting
T-PA release is impaired in obese subjects. In order to have a better mechanistic understanding of t-PA release, we will compare t-PA release to Flow Mediated Vasodilation, Radial Artery Tonometry, and other markers of endothelial function and oxidative stress.
Vanderbilt University has indicated that access to an investigational treatment associated with this study is available outside the clinical trial.

Patients will have flow mediated vasodilation and radial artery tonometry performed. They will then receive 0, 10, 20, 40 ng/100cc/min of intrabrachial bradykinin. Strain gauge plethysmography and blood sampling at each dose will be done to evaluate t-PA release. Blood will also be drawn for other biomarkers.
Intrabrachial - 0, 10, 20, 40 ng/100cc/min over 5 minutes at each dose.
