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. … See more FMD is a noninvasive measure of blood vessel health (endothelial dysfunction ) which (when low) is at least as predictive of cardiovascular disease as traditional risk factors.
