Item Associations with health-related quality of life after intracerebral haemorrhage: pooled analysis of INTERACT studies(BMJ Publishing Group, 2017) Delcourt, Candice; Zheng, Danni; Chen, Xiaoying; Hackett, Maree; Arima, Hisatomi; Hata, Jun; Heeley, Emma; Al-Shahi Salman, Rustam; Woodward, Mark; Huang, Yining; Robinson, Thompson; Lavados, Pablo; Lindley, Richard I; Stapf, Christian; Davies, Leo; Chalmers, John; Anderson, Craig; Sato, Shoichiro; INTERACT InvestigatorsBACKGROUND AND PURPOSE: Limited data exist on health-related quality of life (HRQoL) after intracerebral haemorrhage (ICH). We aimed to determine baseline factors associated with HRQoL among participants of the pilot and main phases of the Intensive Blood Pressure Reduction in Acute Cerebral Haemorrhage Trials (INTERACT 1 and 2). METHODS: The INTERACT studies were randomised controlled trials of early intensive blood pressure (BP) lowering in patients with ICH (<6 hours) and elevated systolic BP (150-220 mm Hg). HRQoL was determined using the European Quality of Life Scale (EQ-5D) at 90 days, completed by patients or proxy responders. Binary logistic regression analyses were performed to identify factors associated with poor overall HRQoL. RESULTS: 2756 patients were included. Demographic, clinical and radiological factors associated with lower EQ-5D utility score were age, randomisation outside of China, antithrombotic use, high baseline National Institutes of Health Stroke Scale (NIHSS) score, larger ICH, presence of intraventricular extension and use of proxy responders. High (≥14) NIHSS score, larger ICH and proxy responders were associated with low scores in all five dimensions of the EQ-5D. The NIHSS score had a strong association with poor HRQoL (p<0.001). Female gender and antithrombotic use were associated with decreased scores in dimensions of pain/discomfort and usual activity, respectively. CONCLUSIONS: Poor HRQoL was associated with age, comorbidities, proxy source of assessment, clinical severity and ICH characteristics. The strongest association was with initial clinical severity defined by high NIHSS score.Item Intracerebral hemorrhage location and outcome among INTERACT2 participants.(American Academy of Neurology, 2017) INTERACT2 Investigators; Delcourt, Candice; Sato, Shoichiro; Zhang, Shihong; Sandset, Else Charlotte; Zheng, Danni; Chen, Xiaoying; Hackett, Maree L.; Arima, Hisatomi; Hata, Jun; Heeley, Emma; Al-Shahi Salman, Rustam; Robinson, Thompson; Davies, Leo; Lavados, Pablo; Lindley, Richard I.; Stapf, Christian; Chalmers, John; Anderson, CraigOBJECTIVE: To clarify associations between intracerebral hemorrhage (ICH) location and clinical outcomes among participants of the main phase Intensive Blood Pressure Reduction in Acute Cerebral Hemorrhage Trial (INTERACT2). METHODS: Associations between ICH sites and poor outcomes (death [6] or major disability [3-5] of modified Rankin Scale) and European Quality of Life Scale (EQ-5D) utility scores at 90 days were assessed in logistic regression models. RESULTS: Of 2,066 patients included in the analyses, associations were identified between ICH sites and poor outcomes: involvement of posterior limb of internal capsule increased risks of death or major disability (odds ratio [OR] 2.10) and disability (OR 1.81); thalamic involvement increased risks of death or major disability (OR 2.24) and death (OR 1.97). 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. ICH encompassing the thalamus and posterior limb of internal capsule were associated with death or major disability, major disability, and poor EQ-5D utility score (OR 1.72, 2.26, and 1.71, respectively). CONCLUSION: Poor clinical outcomes are related to ICH affecting the posterior limb of internal capsule, thalamus, and infratentorial sites. The highest association with death or major disability and poor EQ-5D utility score was seen in ICH encompassing the thalamus and posterior limb of internal capsule.

We determined associations of computed tomographic radiological manifestations of cerebral SVD and outcomes, and in terms of any differential effect of early intensive blood pressure-lowering treatment, in the large-scale Intensive Blood Pressure Reduction in Acute Cerebral Hemorrhage Trial (INTERACT2). METHODS: We graded WML (van Swieten scale), the presence of lacunes, and brain atrophy (2 linear measurements and visual rating) for 2069 of 2839 patients with available baseline brain computed tomography (<6 hours of intracerebral hemorrhage onset) by 3 independent neurologists blind to clinical data. RESULTS: WML grade and 2 linear measurements of brain atrophy were associated with death or major disability at 90 days: multivariable-adjusted odds ratios for WML (grade 3 and 4 versus 0), frontal ratio, and third ventricle Sylvian fissure distance (most versus least severe atrophy quartile) were 1.42 (95% confidence interval, 1.02-1.98), 1.47 (1.08-1.99), and 1.64 (1.21-2.22), respectively (all P for trend <0.05). There was no association between lacunes and outcomes. There were no significant differences in the effects of intensive blood pressure-lowering across subgroups of cerebral SVD. CONCLUSIONS: Preexisting cerebral SVD manifestations of WML and brain atrophy predict poor outcome in acute intracerebral hemorrhage. There is no apparent hazard of early intensive lowering of blood pressure according to the INTERACT2 protocol, in patients with underlying cerebral SVD.Item Significance of Hematoma Shape and Density in Intracerebral Hemorrhage: The Intensive Blood Pressure Reduction in Acute Intracerebral Hemorrhage Trial Study(American Heart Association, Inc., 2016) Delcourt, Candice; Zhang, Shihong; Arima, Hisatomi; Sato, Shoichiro; Salman, Rustam; Wang, Xia; Davies, Leo; Stapf, Christian; Thompson, Robinson; Lavados, Pablo; Chalmers, John; Heeley, Emma; liu, Ming; Lindley, Richard; Anderson, Craig; INTERACT2 investigatorsBACKGROUND AND PURPOSE: In patients with acute intracerebral hemorrhage (ICH), the shape and density of the hematoma are associated with its subsequent growth, but the impact of these parameters on clinical outcome is uncertain. METHODS: Baseline computed tomographic scans and clinical data were obtained in the Intensive Blood Pressure Reduction in Acute Intracerebral Hemorrhage Trial (INTERACT2). Three independent neurologists blind to clinical data assessed ICH for shape and density using a previously described scale. Shape was defined as irregular when the ICH had ≥2 extra lesions added to the ellipsoid-shaped ICH. Density was heterogeneous when there were ≥3 low-density lesions within the ICH. Outcome measures were death and major disability (modified Rankin scale score of 3-5), combined and separate at 90-day postrandomization. Multivariable logistic regression models were used to determine the significance of hematoma characteristics on outcome. RESULTS: There were 2066 patient computed tomographic scans included in the analysis, with 46% and 38% having irregular and heterogeneous ICH, respectively. Irregular shape was independently associated with death/major disability (adjusted odds ratio, 1.60; 95% confidence interval [CI], 1.29-1.98) and major disability alone (adjusted odds ratio, 1.60; 95% CI, 1.31-1.95), but not with death alone (adjusted odds ratio, 0.97; 95% CI, 0.68-1.39). Heterogeneous density was not associated with clinical outcomes (adjusted odds ratio, 1.06; 95% CI, 0.85-1.33), 1.04 (95% CI, 0.73-1.48), and 1.14 (95% CI, 0.93-1.39), respectively, for death/major disability, death alone, and disability alone). CONCLUSIONS: Irregular shape, but not heterogeneous density, is independently associated with poor outcome after ICH. CLINICAL TRIAL REGISTRATION: URL: http://www.clinicaltrials.gov.
