J-shape relation of blood pressure reduction and outcome in acute intracerebral hemorrhage: A pooled analysis of INTERACT2 and ATACH-II individual participant data.

Objective: The aim of this study was to better define the shape of association between the degree ("magnitude") of early (< 1 h) reduction in systolic blood pressure (SBP) and outcomes in patients with acute intracerebral hemorrhage (ICH) through pooled analysis of the second Intensive Blood Pressure Reduction in Acute Cerebral Hemorrhage Trial (INTERACT2) and second Antihypertensive Treatment of Acute Cerebral Hemorrhage (ATACH-II) datasets.

Methods: Association of the continuous magnitude of SBP reduction described using cubic splines and an ordinal measure of the functional outcome on the modified Rankin scale (mRS) scores at 90 days were analyzed in generalized linear mixed models. Models were adjusted for achieved (mean) and variability (standard deviation, SD) of SBP between 1 and 24 h, various baseline covariates, and trial as a random effect.

Intensive blood pressure lowering with nicardipine and outcomes after intracerebral hemorrhage: An individual participant data systematic review.

Background And Aims: Nicardipine has strong, rapidly acting antihypertensive activity. The effects of acute systolic blood pressure levels achieved with intravenous nicardipine after onset of intracerebral hemorrhage on clinical outcomes were determined.

Methods: A systematic review and individual participant data analysis of articles before 1 October 2020 identified on PubMed were performed (PROSPERO: CRD42020213857).

Regional Differences in the Response to Acute Blood Pressure Lowering After Cerebral Hemorrhage.

Objective: To compare the impact of intensive blood pressure (BP) lowering right after intracerebral hemorrhage (ICH) on clinical and hematoma outcomes among patients from different geographic locations, we performed a prespecified subanalysis of a randomized, multinational, 2-group, open-label trial to determine the efficacy of rapidly lowering BP in hyperacute ICH (Antihypertensive Treatment of Acute Cerebral Hemorrhage [ATACH]-2), involving 537 patients from East Asia and 463 recruited outside of Asia.

Methods: Eligible patients were randomly assigned to a systolic BP target of 110 to 139 mm Hg (intensive treatment) or 140 to 179 mm Hg (standard treatment). Predefined outcomes were poor functional outcome (modified Rankin Scale score 4-6 at 90 days), death within 90 days, hematoma expansion at 24 hours, and cardiorenal adverse events within 7 days.

Sex Differences in Blood Pressure-Lowering Therapy and Outcomes Following Intracerebral Hemorrhage: Results From ATACH-2.

Background And Purpose: Evidence regarding sex differences in clinical outcomes and treatment effect following intracerebral hemorrhage is limited. Using the ATACH-2 trial (Antihypertensive Treatment in Intracerebral Hemorrhage-2) data, we explored whether sex disparities exist in outcomes and response to intensive blood pressure (BP)-lowering therapy.

Methods: Eligible intracerebral hemorrhage subjects were randomly assigned to intensive (target systolic BP, 110-139 mm Hg) or standard (140-179 mm Hg) BP-lowering therapy within 4.

Late Neurological Deterioration after Acute Intracerebral Hemorrhage: A post hoc Analysis of the ATACH-2 Trial.

Background: Neurological deterioration (ND) has a major influence on the prognosis of intracerebral hemorrhage (ICH); however, factors associated with ND occurring after 24 h of ICH onset are unknown.

Methods: We performed exploratory analyses of data from the Antihypertensive Treatment of Acute Cerebral Hemorrhage 2 trial, which compared intensive and standard blood pressure lowering treatment in ICH. NDs were captured on the adverse event case report form.
