Diurnal blood-pressure variations in haemodialysis and CAPD patients

60 patients total: 20 hemodialysis patients (10 normotensive, 10 hypertensive), 20 continuous ambulatory peritoneal dialysis (CAPD) patients (11 normotensive, 9 hypertensive), and 20 control patients with normal renal function (9 normotensive, 11 hypertensive). Antihypertensive drugs were discontinued for at least 3 weeks prior to the study.

Ambulatory blood pressure monitoring (day-time and night-time) over a 3-day interdialytic period for hemodialysis patients, and over 24 hours for CAPD patients.

Ambulatory blood pressure monitoring over 24 hours in control patients with normal renal function.
