Project description:Intracerebral hemorrhage remains a challenging worldwide clinical problem with no proven treatments. In the acute phase of the illness, there has been some controversy regarding the appropriate management of elevated blood pressure. Recently published and ongoing clinical trials are beginning to shed some light on appropriate blood pressure management in acute intracerebral hemorrhage. This brief review focuses on these trials. In the next few years, it is hoped that clinical uncertainty regarding this issue will be obviated after completion of these trials.

Project description:ObjectivesTo investigate the effects of intensive blood pressure (BP) lowering according to baseline BP levels and optimal achieved BP levels in patients with acute intracerebral hemorrhage (ICH).MethodsINTERACT2 was an open, blinded endpoint, randomized controlled trial in 2,839 patients with ICH within 6 hours of onset and elevated systolic BP (SBP) (150-220 mm Hg) who were allocated to receive intensive (target SBP <140 mm Hg within 1 hour, with lower limit of 130 mm Hg for treatment cessation) or guideline-recommended (target SBP <180 mm Hg) BP-lowering treatment. Outcome was physical function across all 7 levels of the modified Rankin Scale at 90 days.ResultsAnalysis of the randomized comparisons showed that intensive BP lowering produced comparable benefits on physical function at 90 days in 5 subgroups defined by baseline SBP of <160, 160-169, 170-179, 180-189, and ≥190 mm Hg (p homogeneity = 0.790). Analyses of achieved BP showed linear increases in the risk of physical dysfunction for achieved SBP above 130 mm Hg for both hyperacute (1-24 hours) and acute (2-7 days) phases while modest increases were also observed for achieved SBP below 130 mm Hg.ConclusionsIntensive BP lowering appears beneficial across a wide range of baseline SBP levels, and target SBP level of 130-139 mm Hg is likely to provide maximum benefit in acute ICH.Classification of evidenceThis study provides Class I evidence that the effect of intensive BP lowering on physical function is not influenced by baseline BP.

Project description:ObjectiveTo assess race-ethnic differences in acute blood pressure (BP) following intracerebral hemorrhage (ICH) and the contribution to disparities in ICH outcome.MethodsBPs in the field (emergency medical services [EMS]), emergency department (ED), and at 24 hours were compared and adjusted for group differences between non-Hispanic black (black), non-Hispanic white (white), and Hispanic participants in the Ethnic Racial Variations of Intracerebral Hemorrhage case-control study. Outcome was obtained by modified Rankin Scale (mRS) score at 3 months. We analyzed race-ethnic differences in good outcome (mRS ≤ 2) and mortality after adjusting for baseline differences and included BP recordings in this model.ResultsOf 2,069 ICH cases enrolled, 30% were white, 37% black, and 33% Hispanic. Black and Hispanic patients had higher EMS and ED systolic and diastolic BPs compared with white patients (p = 0.0001). Although attenuated, at 24 hours after admission, black patients had higher systolic and diastolic BPs. After adjusting for baseline differences, significant race/ethnic differences persisted for EMS systolic, ED systolic and diastolic, and 24-hours diastolic BP. Only ED systolic and diastolic BP was associated with poor functional outcome, and no BP predicted mortality. We found no race-ethnic differences in 3-month functional outcome or mortality after adjusting for group differences, including acute BPs.ConclusionsAlthough black and Hispanic patients had higher BPs than white patients at presentation, we did not find race-ethnic disparities in 3-month functional outcome or mortality. ED systolic and diastolic BP was associated with poor functional outcome, but not mortality, in this race-ethnically diverse population.

Project description:Intracerebral hemorrhage (ICH) is the deadliest type of stroke and up to half of patients die in hospital. Blood pressure management, coagulopathy reversal, and intracranial pressure control are the mainstays of acute ICH treatment. Prevention of hematoma expansion and minimally invasive hematoma evacuation are promising therapeutic strategies under investigation. This article provides an updated review on ICH diagnosis and management in the emergency department.

Project description:Opinion statementIntracerebral hemorrhage is a medical emergency. It is the most deadly and disabling form of stroke, and no individual therapy has been demonstrated to improve outcome. However, it appears that aggressive medical care in general, and management by neuroscience specialists in particular, offers substantial benefit. Therefore, providing the best supportive care based on currently available evidence may well improve outcomes. Airway management and management of blood pressure aimed at maximizing cerebral perfusion while minimizing ongoing bleeding, as well as rapid reversal of anticoagulation, are likely to be important in the early phase. Additionally, efforts should be undertaken to provide careful glucose management and temperature management and to maximize cerebral perfusion pressure. Selected patients are likely to benefit from external ventricular drainage or even hematoma evacuation. Except in rare circumstances, most patients should be managed in a neuroscience intensive care unit during the acute phase. Some patients appear to have no reasonable likelihood of recovery and can be considered for limitations of care such as Do Not Resuscitate orders or Comfort Measures Only orders. However, it can be difficult to accurately predict long-term outcome in the acute phase; formal prognostic tools should be used to offer information to patients and their families. After the hemorrhage has stabilized, efforts to minimize complications include thromboembolism prophylaxis, physical therapy, and acute rehabilitation.

Project description:Background and Purpose- It is unknown whether admission systolic blood pressure (SBP) differs among causes of intracerebral hemorrhage (ICH). We sought to elucidate an association between admission BP and ICH cause. Methods- We compared admission SBP across ICH causes among patients in the Cornell Acute Stroke Academic Registry, which includes all adults with ICH at our center from 2011 through 2017. Trained analysts prospectively collected demographics, comorbidities, and admission SBP, defined as the first recorded value in the emergency department or on transfer from another hospital. ICH cause was adjudicated by a panel of neurologists using the SMASH-U criteria. We used ANOVA to compare mean admission SBP among ICH causes. We used multiple linear regression to adjust for age, sex, race, Glasgow Coma Scale score, and hematoma size. In secondary analyses, we compared hourly SBP measurements during the first 72 hours after admission, using mixed-effects linear models adjusted for the covariates above plus antihypertensive agents. Results- Among 484 patients with ICH, admission SBP varied significantly across ICH causes, ranging from 138 (±24) mm Hg in those with structural vascular lesions to 167 (±35) mm Hg in those with hypertensive ICH (P<0.001). The mean admission SBP in hypertensive ICH was 17 (95% CI, 11-24) mm Hg higher than in ICH of all other causes combined. These differences remained significant after adjustment for age, sex, race, Glasgow Coma Scale score, and hematoma size (P<0.001), and this persisted throughout the first 72 hours of hospitalization (P<0.001). Conclusions- In a single-center ICH registry, SBP varied significantly among ICH causes, both on admission and during hospitalization. Our results suggest that BP in the acute post-ICH setting is at least partly associated with ICH cause rather than simply representing a physiological reaction to the ICH itself.

Project description:BackgroundTo highlight the heterogeneity of acute temporal blood pressure (BP) changes in the ATACH-2 trial (Antihypertensive Treatment of Acute Cerebral Hemorrhage-2) and associations with the outcomes of intracerebral hemorrhage.MethodsOne thousand patients with acute intracerebral hemorrhage, who had been randomized to intensive (110-139 mm Hg) or standard (140-179 mm Hg) systolic BP (SBP) lowering with intravenous nicardipine in ATACH-2 from 2011 to 2015, were analyzed about temporal changes in hourly maximum SBP up to 24 hours after randomization using group-based trajectory modeling. Outcomes included death or disability (modified Rankin Scale score 4-6) at 3 months, neurological deterioration within 24 hours (≥2-point decrease in Glasgow Coma Scale score or ≥4-point increase in National Institutes of Health Stroke Scale score), and acute kidney injury (≥0.3 mg/dL within 48 hours or ≥1.5-fold increase in serum creatinine) within 7 days after onset.ResultsGroup-based trajectory modeling revealed 4 SBP trajectory groups: moderate SBP (from ≈190 mm Hg at hospital arrival to 150-160 mm Hg after randomization; n=298), moderate-to-low SBP (from ≈190 mm Hg to <140 mm Hg; n=395), high-to-low SBP (from >210 mm Hg to <140 mm Hg; n=134), and high SBP (from >210 mm Hg to 160-170 mm Hg; n=173). Patients with intensive treatment accounted for 11.1%, 88.6%, 85.1%, and 1.7% of each group, respectively. Compared with the moderate-to-low SBP group, the high-to-low SBP group showed increased risks of death or disability at 3 months (adjusted odds ratio, 2.29 [95% CI, 1.24-4.26]) and acute kidney injury (adjusted odds ratio, 3.50 [95% CI, 1.83-6.69]), while no increase in neurological deterioration was seen in this group (adjusted odds ratio, 0.48 [95% CI, 0.20-1.13]). The moderate SBP and high SBP groups showed no significant risk differences for such outcomes.ConclusionsData-driven observation using a group-based trajectory modeling approach may be useful to clarify the relationship between antihypertensive treatment, temporal SBP changes, and outcomes in acute intracerebral hemorrhage.RegistrationURL: https://www.Clinicaltrialsgov; Unique identifier: NCT01176565.

Project description:Intraventricular hemorrhage (IVH) extension is common following acute intracerebral hemorrhage (ICH) and is associated with poor prognosis.To determine whether intensive blood pressure (BP)-lowering therapy reduces IVH growth.Pooled analyses of the Intensive Blood Pressure Reduction in Acute Cerebral Hemorrhage Trials (INTERACT1 and INTERACT2) computed tomography (CT) substudies; multicenter, open, controlled, randomized trials of patients with acute spontaneous ICH and elevated systolic BP, randomly assigned to intensive (<140 mm Hg) or guideline-based (<180 mm Hg) BP management. Participants had blinded central analyses of baseline and 24-hour CT. Association of BP lowering to IVH growth was assessed in analysis of covariance.There was no significant difference in adjusted mean IVH growth following intensive (n = 228) compared to guideline-recommended (n = 228) BP treatment (1.6 versus 2.2 ml, respectively; p = 0.56). Adjusted mean IVH growth was nonsignificantly greater in patients with a mean achieved systolic BP ?160 mm Hg over 24 h (3.94 ml; p trend = 0.26).Early intensive BP-lowering treatment had no clear effect on IVH in acute ICH.

Project description:Background In acute intracerebral hemorrhage, both elevated blood pressure (BP) and antithrombotic treatment are associated with poor outcome. Our aim was to explore interactions between antithrombotic treatment and prehospital BP. Methods and Results This observational, retrospective study included adult patients with spontaneous intracerebral hemorrhage diagnosed by computed tomography within 24 hours, admitted to a primary stroke center during 2012 to 2019. The first recorded prehospital/ambulance systolic and diastolic BP were analyzed per 5 mm Hg increment. Clinical outcomes were in-hospital mortality, shift on the modified Rankin Scale at discharge, and mortality at 90 days. Radiological outcomes were initial hematoma volume and hematoma expansion. Antithrombotic (antiplatelet and/or anticoagulant) treatment was analyzed both together and separately. Modification of associations between prehospital BP and outcomes by antithrombotic treatment was explored by multivariable regression with interaction terms. The study included 200 women and 220 men, median age 76 (interquartile range, 68-85) years. Antithrombotic drugs were used by 252 of 420 (60%) patients. Compared with patients without, patients with antithrombotic treatment had significantly stronger associations between high prehospital systolic BP and in-hospital mortality (odds ratio [OR], 1.14 versus 0.99, P for interaction 0.021), shift on the modified Rankin Scale (common OR, 1.08 versus 0.96, P for interaction 0.001), and hematoma volume (coef. 0.03 versus -0.03, P for interaction 0.011). Conclusions In patients with acute, spontaneous intracerebral hemorrhage, antithrombotic treatment modifies effects of prehospital BP. Compared with patients without, patients with antithrombotic treatment have poorer outcomes with higher prehospital BP. These findings may have implications for future studies on early BP lowering in intracerebral hemorrhage.
