Background There is persistent uncertainty over the benefits of early intensive systolic blood pressure lowering in acute intracerebral hemorrhage. In particular, over the timing, target, and intensity of systolic blood pressure control for optimum balance of potential benefits (i.e. functional recovery) and risks (e.g. cerebral ischemia). Aims To determine associations of early systolic blood pressure lowering parameters and outcomes in patients with a hypertensive response in acute intracerebral hemorrhage. Secondary aims are to identify the modifying effects of patient characteristics and an optimal systolic blood pressure lowering profile. Methods Individual participant data pooled analyses of two large, multicenter, randomized controlled trials specifically undertaken to assess the effects of early intensive systolic blood pressure reduction on clinical outcomes in acute intracerebral hemorrhage: the Intensive Blood Pressure in Acute Intracerebral Hemorrhage Trial (INTERACT2) and the Antihypertensive Treatment of Acute Cerebral Hemorrhage (ATACH-II) trial. Combined data will include baseline characteristics; systolic blood pressure in the first 24 h; process of care measures; and key efficacy and safety outcomes. Outcomes The primary outcome is functional recovery, defined by an ordinal distribution of scores on the modified Rankin scale at 90 days post-randomization. Secondary outcomes include various standard binary cut-points for disability-free survival on the modified Rankin scale, and health-related quality of life at 90 days. Safety outcomes include symptomatic hypotension requiring corrective therapy and early neurologic deterioration within 24 h, and deaths, any serious adverse event, and cardiac and renal serious adverse events, within 90 days. Discussion A pre-determined protocol was developed to facilitate successful collaboration and reduce analysis bias arising from prior knowledge of the findings.

Multicenter Prospective Observational Study

Background: Little has been investigated about associations between timing of blood pressure lowering and clinical outcome of intracerebral hemorrhage (ICH). Methods: The Stroke Acute Management with Urgent Risk-factor Assessment and Improvement (SAMURAI)-ICH Study is a multicenter, prospective, observational study investigating the safety and feasibility of early (within 3 hours from symptom onset) systolic blood pressure (SBP) reduction to less than 160 mmHg with intravenous nicardipine for acute hypertension in patients with spontaneous ICH. We retrospectively examined the relationship between time from onset, CT imaging, and initiation of antihypertensive treatment to target SBP achievement and hematoma growth in ICH patients. Hematoma growth was defined as an absolute growth of ≥ 6 ml from baseline to second imaging at 24 (±6) hours after the initiation of antihypertensive treatment. Results: Among 211 patients (81 women (38.4%), mean age 66 years), mean baseline hematoma volume was 13 ml and hematoma growth was seen in 36 (17.1%) patients. Time from image to target SBP and time from treatment to target SBP were significantly shorter in patients without hematoma growth than those with ( P = 0.043 and P = 0.032, respectively), whereas there was not significant difference in time from onset to target SBP between the two groups ( P = 0.177). Lower quartiles of time from image to target SBP and time from treatment to target SBP had lower incidences of hematoma growth (P trend = 0.023 and 0.037, respectively, Cochran-Armitage test), whereas there was not significant trend in time from onset to target SBP ( P = 0.074). The lowest quartile of time from image to target SBP was negatively associated with hematoma growth on multivariate logistic regression (odds ratio 0.182, 95% confidential interval 0.038-0.867, P = 0.032). Conclusions: Early achievement to target SBP <160 mmHg was negatively associated with hematoma growth in ICH patients.
