Hypertension and a high incidence of cardiovascular morbidity and mortality often accompany end-stage renal disease. Causes of the hypertension include abnormalities of extracellular fluid volume, increased activity of the renin-angiotensin system, dysfunction of the autonomic nervous system, and deficiency of vasodilator substances. Treatment is not detrimental to residual renal function and may enhance the quality of survival. Several types of therapy are available that may be used sequentially or in combination. New antihypertensive drugs and improved blood-cleansing devices allow a more optimistic outlook on long-term survival in end-stage renal disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
