title: Blood pressure control and recurrence of hypertensive brain hemorrhage.
abstract: OBJECTIVE
  Recent studies have demonstrated that recurrence of hypertensive brain hemorrhage (HBH) is not uncommon. However, risk factors for the recurrence of HBH have not been evaluated systematically.
  
  
  METHODS
  We analyzed 74 patients with HBH who were admitted to our clinic and followed up as outpatients for a mean of 2.8 years. Blood pressure (BP) and other clinical features were compared between the groups of patients with and without rebleeding. We determined the recurrence rate of HBH in relation to BP.
  
  
  RESULTS
  Diastolic BP was significantly higher in the recurrence group than in the nonrecurrence group (88+/-8 versus 82+/-7 mm Hg; P=0.04). Systolic BP and other clinical variables were not different between the groups. The recurrence rate was 10.0% per patient-year in patients with diastolic BP >90 mm Hg and <1.5% in those with lower diastolic BP (P<0.001). No patients with diastolic BP <70 mm Hg experienced rebleeding.
  
  
  CONCLUSIONS
  Higher diastolic BP was related to an increased rate of rebleeding. Diastolic BP >90 mm Hg may be regarded as a factor predictive of the recurrence of HBH.
