title: [Comparative study of ambulatory blood pressure between renovascular hypertensive and essential hypertensive patients].
abstract: OBJECTIVE
  To compare 24 h ambulatory blood pressure changes between patients with renovascular hypertension and essential hypertension.
  
  
  METHODS
  The 24 h ambulatory blood pressure of patients with age and gender matched renovascular hypertension (RVH, n = 51) was compared with that of patients with essential hypertension (EH, n = 51).
  
  
  RESULTS
  The 24 h, daytime and nighttime systolic blood pressures (SBP), diastolic blood pressures (DBP) and pulse pressures (PP) in RVH were significantly higher than in EH (all P < 0.05), especially the nocturnal SBP (P < 0.05). The SBP and DBP loads in RVH were 58.96% and 35.98% respectively, while blood pressure loads were around 20.00% in EH (P < 0.05). In patients with RVH, The nocturnal blood pressure fall was 5.39%, and only 27.50% patients were dippers, while the nocturnal blood pressure fall was 10.36% and 60.8% patients were dippers in EH.
  
  
  CONCLUSIONS
  RVH patients have higher dynamic BP, PP, BP loads and blunted diurnal rhythm compared to those with EH.
