Blood Pressure Control and Recurrence of Hypertensive Brain Hemorrhage

BACKGROUND AND PURPOSE: 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 90 mm Hg may be regarded as a factor predictive of the recurrence of HBH.
