Hypertension I: Structure of Small Arteries in Hypertension

Dr. Heagerty (0861)

Robert M.K.W. Lee

If eutrophic inward remodeling, i.e. a permanent reduction of the lumen size is part of the cause of elevated peripheral resistance in essential hypertension, then theoretically, vasodilators should not be able to lower BP in these patients.  But vasodilators do lower BP in these patients.  Is it possible that in hypertension, control of resistence resides somewhere else, e.g. in the muscular arteries upstream?
