<jats:sec><jats:title>Background</jats:title><jats:p>The effect of renal impairment in patients who receive intravenous thrombolysis for acute ischemic stroke (AIS) is unclear. We aimed to determine the associations of renal impairment and clinical outcomes and any modification of the effect of intensive versus guideline-recommended blood pressure (BP) control in the BP arm of the International Enhanced Control of Hypertension and Thrombolysis Stroke Study (ENCHANTED).</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>We conducted a <jats:italic>post-hoc</jats:italic> analysis of the ENCHANTED BP arm, which involved 2,196 thrombolyzed AIS patients.

However, the difference in death or major disability (mRS 3–6) was not significant between groups.

<jats:sec><jats:title>Introduction</jats:title><jats:p> Reports vary on how sex influences the management and outcome from acute intracerebral haemorrhage. We aimed to quantify sex disparities in clinical characteristics, management, including response to blood pressure lowering treatment, and outcomes in patients with acute intracerebral haemorrhage, through interrogation of two large clinical trial databases. </jats:p></jats:sec><jats:sec><jats:title>Patients and Methods</jats:title><jats:p> Post-hoc pooled analysis of the Intensive Blood Pressure Reduction in Acute Cerebral Haemorrhage trials 1 and 2, where patients with a hypertensive response (systolic, 150–220 mmHg) after spontaneous intracerebral haemorrhage (<6 h) were randomised to intensive (target <140 mmHg <1 h) or guideline-recommended (<180 mmHg) blood pressure lowering treatment. The interaction of sex on early haematoma growth (24 h), death or major disability (modified Rankin scale scores 3–6 at 90 days), and effect of randomised treatment were determined in multivariable logistic regression models adjusted for baseline confounding variables. </jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p> In 3233 participants, 1191 (37%) were women who were significantly older, had higher baseline National Institutes of Health Stroke Scale scores and smaller haematoma volumes compared to men. Men had higher three-month mortality (odds ratio 1.48, 95% confidence interval 1.10–2.00); however, there was no difference between women and men in the combined endpoint of death or major disability. There were no significant sex differences on mean haematoma growth or effect of randomised blood pressure lowering treatment. </jats:p></jats:sec><jats:sec><jats:title>Discussion</jats:title><jats:p> Men included in the Intensive Blood Pressure Reduction in Acute Cerebral Haemorrhage trials had more comorbidities, larger baseline haematoma volumes and higher mortality after adjustment for age, as compared with women. </jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p> Men included in the Intensive Blood Pressure Reduction in Acute Cerebral Haemorrhage trials had a greater odds of dying after intracerebral haemorrhage than women, which could not be readily explained by differing casemix or patterns of blood pressure management. </jats:p></jats:sec><jats:sec><jats:title>Clinical trial registration</jats:title><jats:p> The Intensive Blood Pressure Reduction in Acute Cerebral Haemorrhage trials studies are registered with ClinicalTrials.gov (NCT00226096 and NCT00716079). </jats:p></jats:sec>

<jats:sec> <jats:title>Background and Purpose—</jats:title> <jats:p>Intraventricular hemorrhage (IVH) with spontaneous intracerebral hemorrhage indicates a poor prognosis but uncertainty exists over the pattern of association. We aimed to elucidate risk associations of IVH and outcome in the Intensive Blood Pressure Reduction in Acute Cerebral Hemorrhage Trial (INTERACT2) data set.</jats:p> </jats:sec> <jats:sec> <jats:title>Methods—</jats:title> <jats:p>INTERACT2 was an international prospective, open-blinded end point, randomized controlled trial in 2839 patients with intracerebral hemorrhage (<6 hours) with elevated systolic blood pressure randomly assigned to intensive (target systolic blood pressure <140 mm Hg) or guideline-based (systolic blood pressure <180 mm Hg) blood pressure management. Associations of baseline IVH in 740 of 2613 (28%) patients and poor outcomes (death and major disability defined on the modified Rankin Scale) at 90 days were determined in linear and logistic regression models.</jats:p> </jats:sec> <jats:sec> <jats:title>Results—</jats:title> <jats:p> Patients with IVH were significantly older and with greater neurological impairment, history of ischemic stroke, and larger hematomas more often deep hemisphere located at presentation, after adjustment for other baseline variables. Death or major disability occurred in 66% with IVH versus 49% in intracerebral hemorrhage–alone patients (adjusted odds ratio, 1.68; 95% confidence interval, 1.38–2.06; <jats:italic>P</jats:italic> <0.01). Associations of IVH volume and clinical outcomes were strong and near continuous. Adjusted analyses by thirds of IVH volume indicate thresholds of ≈5 and 10 mL for significantly increased odds of death and death or major disability, respectively. </jats:p> </jats:sec> <jats:sec> <jats:title>Conclusions—</jats:title> <jats:p>A strong association exists between the amount of IVH and poor outcome in intracerebral hemorrhage. An IVH volume of 5 to 10 mL emerges as a significant threshold for decision making on prognosis in these patients.</jats:p> </jats:sec> <jats:sec> <jats:title>Clinical Trial Registration—</jats:title> <jats:p> URL: <jats:ext-link xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="uri" xlink:href="http://www.clinicaltrials.gov">http://www.clinicaltrials.gov</jats:ext-link> .

Involvement of the posterior limb of the internal capsule, thalamus, and infratentorial sites were each associated with poor EQ-5D utility score (≤0.7 [median]; OR 1.87, 2.14, and 2.81, respectively). Posterior limb of internal capsule involvement was strongly associated with low scores across all health-related quality of life domains.

<jats:sec> <jats:title>Background and Purpose—</jats:title> <jats:p>Infratentorial intracerebral hemorrhage (ICH) has a poor outcome but is rarely analyzed by cerebellar versus brain stem location. We evaluated this relationship and clinical outcomes among participants of the INTERACT 1 and 2 (Intensive Blood Pressure Reduction in Acute Cerebral Hemorrhage Trials).</jats:p> </jats:sec> <jats:sec> <jats:title>Methods—</jats:title> <jats:p>Participants with brain stem and cerebellar ICH were compared. Logistic regression models were used to compare outcomes of death or major disability and quality of life.</jats:p> </jats:sec> <jats:sec> <jats:title>Results—</jats:title> <jats:p>Of 195 included patients, 92 (47%) and 103 (53%) had brain stem and cerebellar ICH, respectively. Patients with brain stem ICH were younger (mean [SD] age, 59±13 versus 70±11 years), less female (28.3% versus 50.5%), with higher admission National Institutes of Health Stroke Scale scores (median [interquartile range], 6 [4–10) versus 3 [2–8]), less prior ICH (3% versus 17%), smaller ICH volumes (1.6 mL [1.0–2.8 mL] versus 5.1 mL [2.6–10.7 mL]), and less intraventricular extension (3% versus 39%) than those with cerebellar ICH. Brain stem ICH had higher mortality (odds ratio, 37.1; 95% CI, 1.99–692.27) and worse scores in the European Quality of Life Scale (EQ-5D) pain domain (odds ratio, 3.36; 95% CI, 1.38–8.20).</jats:p> </jats:sec> <jats:sec> <jats:title>Conclusions—</jats:title> <jats:p>Cerebellar and brain stem ICH differ in their clinical characteristics and prognosis, with the latter being associated with higher case fatality and worse EQ-5D scores in the pain domain.</jats:p> </jats:sec> <jats:sec> <jats:title>Clinical Trial Registration—</jats:title> <jats:p> URL: <jats:ext-link xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="uri" xlink:href="https://www.clinicaltrials.gov">https://www.clinicaltrials.gov</jats:ext-link> .
