WebJan 16, 2002 · Flow-mediated vasodilation is an endothelium-dependent process that reflects the relaxation of a conduit artery when exposed to increased shear stress. Increased flow, and thereby increased shear stress, through the brachial artery occurs during postocclusive reactive hyperemia. Flow-mediated dilation (FMD) refers to dilation (widening) of an artery when blood flow increases in that artery. The primary cause of FMD is release of nitric oxide by endothelial cells. To determine FMD, brachial artery dilation following a transient period of forearm ischemia is measured using ultrasound. Because the value of FMD can be compromised when improperly applied, attempts have been made to standardize the methodology for measuring FMD. Web2-mediated vasodilatation have been identified. For exam-ple, in human coronary arterioles, mitochondrial respiratory chain- and NADPH oxidase-derived H 2O 2 may be involved in flow-mediated dilatation and bradykinin-induced relaxation, respectively.54,55 3.3 34Regulatory mechanisms of physiologically relevant H 2O 2 porthgain facts
