- Change in flow mediated dilation [ Time Frame: Change from baseline at 15 minutes after ischemia-reperfusion injury ]Flow mediated dilation is a measure of vascular function and is measured as the outcome before and after an injury to the inner lining of the artery.
- Change in low flow mediated constriction [ Time Frame: Change from baseline at 15 minutes after ischemia-reperfusion injury ]low flow mediated constriction is a measure of vascular function and is measured to establish the impact of a vascular injury
