VASCULAR FUNCTION IN OSA

A number of pathophysiological phenomena linked to sleep disordered br eathing are likely to affect vascular function. This report briefly re views current knowledge regarding neurogenic vascular tone and a numbe r of circulating hormones with vascular actions in obstructive sleep a pnea (OSA). New evidence suggesting a role of the vascular endothelium in the development of vascular disease in OSA is also presented.
