ObjectiveTo study the effect of intensive blood pressure reduction in patients with moderate to severe intracerebral hemorrhage (ICH) within the subjects recruited in Antihypertensive Treatment of Acute Cerebral Hemorrhage 2 trial.DesignRandomized, multicenter, 2 group, open-label clinical trial.SettingA total of 110 sites in the USA, Japan, China, Taiwan, South Korea, and Germany.PatientsA total of 1,000 patients underwent randomization from May 2011 till September 2015.InterventionsWe analyzed the effect of intensive (goal 110-139 mm Hg) over standard (goal 140-179 mm Hg) systolic blood pressure (SBP) reduction using intravenous nicardipine within 4.5 h of symptom onset in moderate to severe grade subjects with ICH in a non-prespecified analysis. Moderate to severe grade was defined by Glasgow Coma Scale score <13 or baseline National Institutes of Health Stroke Scale score ≥10 or baseline intraparenchymal hemorrhage volume ≥30 mL or presence of intraventricular hemorrhage. The primary outcome was death or disability (score 4-6 on the modified Rankin scale) at 3 months after randomization ascertained by a blinded investigator.Measurements And Main ResultsOf a total of 682 subjects who met the definition of moderate to severe grade (mean age 61.9 ± 13.1 years, 62.5% men) with a mean baseline SBP of 174.7 ± 24.8 mm Hg, the frequency of hematoma expansion was significantly lower among subjects randomized to intensive SBP reduction than among subjects randomized to standard SBP reduction (20.4 vs. 27.9%, relative risk [RR]: 0.7; 95% confidence interval [CI]: 0.55-0.96). The primary endpoint of death or disability was observed in 52.5% (170/324) of subjects receiving intensive SBP reduction and 48.9% (163/333) of subjects receiving standard SBP reduction (RR: 1.1; 95% CI: 0.9-1.2).ConclusionsIntensive SBP lowering reduced the frequency of hematoma expansion but did not reduce the rate of death or disability in patients with moderate to severe grade ICH.© 2020 S.
