简要总结
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.

研究组 & 干预措施
Bradykinin
Experimental
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.
干预措施: Bradykinin (Drug)
结局指标
主要结局
Peak t-PA Release

次要结局
- Peak FMD(Single Study Day)
- Radial Artery Elasticity(Single Study Visit)
- Lipid Levels, PAI-1 Levels, CRP Levels, F2 Isoprostanes and Other Biomarkers of Inflammation and Obesity.(Single Study Day)
