The management of hypertension in hemodialysis and CAPD patients

Abstract

Patients with chronic kidney disease progress to end stage renal disease and about 86% are diagnosed hypertensives. Hypertension is a risk factor for cardiovascular disease which is the main cause of morbidity and mortality in the dialysis population. Pre and post-dialysis blood pressure values of <140/90 mmHg are recommended as the optimal blood pressure. The extra-cellular volume (ECV) expansion is the main pathophysiological determinant of hypertension in dialysis patients. The efforts should be made to correctly estimate and achieve the patients dry body weigh and to limit dietary sodium intake. Angiotensin II receptor antagonists, beta blockers and calcium channel blockers are recommended as first choice drugs. Beta blockers and calcium channel blockers have been associated with reduced cardiovascular mortality and give their protective effects in patients at high risk. Antihypertensive drug therapies can effectively reduce blood pressure and are needed by the vast majority of hemodialysis patients.
