Abstract

Background: The optimal treatment of high blood pressure (BP) after acute intra-cerebral hemorrhage (ICH) is controversial.

Summary: The aim of the study was to evaluate the safety and efficacy of early intensive vs. conservative BP lowering treatment in patients with ICH. Randomized controlled trials with active and control groups receiving intensive and conservative BP lowering treatments were identified. The following outcomes were assessed: 3-month mortality and combined death or major disability, 24-h hematoma growth, early neurological deterioration, occurrence of hypotension, severe hypotension, and serious treatment-emergent adverse events. Five trials were included involving 4,350 participants, 2,162 and 2,188 for intensive and conservative treatment groups, respectively. The pooled risk ratio of 3-month death or major disability was 0.96 (0.91-1.01) and the weighted mean difference in absolute hematoma growth was -1.53 (95% CI -2.94 to -0.12) mL in the intensive compared to conservative BP-lowering. There were no differences across the treatments in the incidence rates of 3-month mortality, early neurological deterioration, hypotension, and treatment-related adverse effects other than renal events. Key Messages: The early intensive anti-hypertensive treatment was overall safe and reduced the hematoma expansion in patients presenting with acute-onset spontaneous ICH and high BP levels.
