title: [Long-term development of blood pressure profile in hypertensive hemodialysis patients].
abstract: OBJECTIVE
  The prognostic value of nocturnal blood pressure (BP) in hemodialysis patients has been well established. The aim of this study was to evaluate the long-term outcome of ambulatory BP in hypertensive hemodialysis patients.
  
  
  METHODS
  Medical records of all hemodialysis patients seen for uncontrolled hypertension between 1993 and 1999 and who underwent an ambulatory blood pressure measurements (ABPM) were retrospectively studied. Uncontrolled hypertension was defined as office BP = 140/90 mmHg and 24 h ABP = 125/80 mmHg. Patients who underwent a second ABPM after an interval of at least 1 year were included in the study. Demographic characteristics, medical history, cardiovascular risk factors and treatments were recorded for each patient. A t-test (bilateral) was used to compare BP.
  
  
  RESULTS
  26 patients were included (545 +/- 18.9 years; 14 men). 7 had previous history of cardiovascular disease and 2 were diabetic. At the end of the follow-up (29 +/- 12.8 months), 9 patients (36%) had 24 h BP < 125/80 mmHg. A significant decrease in diurnal and nocturnal BP was observed (p < 0.05). No significant change was observed for office systolic BP and predialytic BP.
  
  
  CONCLUSIONS
  Our data show that a long-term decrease in nocturnal BP can be obtained in hypertensive patients on hemodialysis. With respect to the prognostic value of this criteria, randomised trials could be carried out to determine whether nocturnal BP is superior to office BP as a target for antihypertensive therapy in this population.
