The Effect of CAPO on Hypertension Control: A Report of the National CAPO Registry

Abstract

Hypertension and medication histories were collected on a cohort of 209 randomly selected adult patients from the National CAPD Registry. Seventy-seven percent of the patients had a history of hypertension. Over 92% of hypertensives have a medication history for the problem. Mean reductions in systolic blood pressure of > 11 mm Hg were observed in subsets examined at one month and one year, while diastolic pressure decreases were significant at one month but not at a year. Diuretics were used in 32% of treated hypertensives at baseline, but only 9% of treated patients at one year. With initiation of continuous ambulatory peritoneal dialysis (CAPD), patients are significantly more likely to be classified as normal and less likely to be medically uncontrolled hypertensives. Thirty percent of patients who were receiving antihypertensive medication at baseline were not receiving antihypertensive therapy at one year.
