ABSTRACT: Introduction
The aim of this study was to determine the risk of recurrent intracerebral haemorrhage (ICH), ischaemic stroke, all stroke, any vascular event and all-cause mortality in 30-day survivors of ICH, according to age and sex.Patients and methods
We linked national hospital discharge, population and cause of death registers to obtain a cohort of Dutch 30-day survivors of ICH from 1998 to 2010. We calculated cumulative incidences of recurrent ICH, ischaemic stroke, all stroke and composite vascular outcome, adjusted for competing risk of death and all-cause mortality. Additionally, we compared survival with the general population.Results
We included 19,444 ICH-survivors (52% male; median age 72 years, interquartile range 61-79; 78,654 patient-years of follow-up). First-year cumulative incidence of recurrent ICH ranged from 1.5% (95% confidence interval 0.9-2.3; men 35-54 years) to 2.4% (2.0-2.9; women 75-94 years). Depending on age and sex, 10-year risk of recurrent ICH ranged from 3.7% (2.6-5.1; men 35-54 years) to 8.1% (6.9-9.4; women 55-74 years); ischaemic stroke 2.6% to 7.0%, of all stroke 9.9% to 26.2% and of any vascular event 15.0% to 40.4%. Ten-year mortality ranged from 16.7% (35-54 years) to 90.0% (75-94 years). Relative survival was lower in all age-groups of both sexes, ranging from 0.83 (0.80-0.87) in 35- to 54-year-old men to 0.28 (0.24-0.32) in 75- to 94-year-old women.Discussion
ICH-survivors are at high risk of recurrent ICH, of ischaemic stroke and other vascular events, and have a sustained reduced survival rate compared to the general population.Conclusion
The high risk of recurrent ICH, other vascular events and prolonged reduced survival-rates warrant clinical trials to determine optimal secondary prevention treatment after ICH.

Project description:ObjectiveThe concept of the 'self-fulfilling prophecy' is well established in intracerebral haemorrhage (ICH). The ability to improve prognostication and prediction of long-term outcomes during the first days of hospitalisation is important in guiding conversations around goals of care. We previously demonstrated that incorporating delayed imaging into various prognostication scores for ICH improves the predictive accuracy of 90-day mortality. However, delayed prognostication scores have not been used to predict long-term functional outcomes beyond 90 days.Design, setting and participantsWe analysed data from the ICH Deferoxamine trial to see if delaying the use of prognostication scores to 96 hours after ICH onset will improve performance to predict outcomes at 180 days. 276 patients were included.Interventions and measurementsWe calculated the original ICH score (oICH), modified-ICH score (MICH), max-ICH score and the FUNC score on presentation (baseline), and on day 4 (delayed). Outcomes assessed were mortality and poor functional outcome in survivors (defined as modified Rankin Scale of 4-5) at 180 days. We generated receiver operating characteristic curves, and measured the area under the curve values (AUC) for mortality and functional outcome. We compared baseline and delayed AUCs with non-parametric methods.ResultsAt 180 days, 21 of 276 (7.6%) died. Out of the survivors, 54 of 255 had poor functional outcome (21.2%). The oICH, MICH and max-ICH performed significantly better at predicting 180-day mortality when calculated 4 days later compared with their baseline equivalents ((0.74 vs 0.83, p=0.005), (0.73 vs 0.80, p=0.036), (0.74 vs 0.83, p=0.008), respectively). The delayed calculation of these scores did not significantly improve our accuracy for predicting poor functional outcomes.ConclusionDelaying the calculation of prognostication scores in acute ICH until day 4 improved prediction of 6-month mortality but not functional outcomes.Trial registration numberClinicalTrials.gov Registry (NCT02175225).

Project description:ObjectivesOverwork-related cerebrovascular and cardiovascular diseases (CCVDs) constitute a major occupational and public health issue worldwide. However, to our knowledge, few studies have reported the underlying pathophysiological mechanisms. We aimed to determine whether patients with extreme workload have a greater risk of developing hypertensive intracerebral haemorrhage (ICH) located in the deep brain areas than patients without extreme workload. We also determined the association between the number of hours of overtime work and the risk of developing hypertensive ICH.DesignUnmatched case-control study.SettingDatabase of patients claiming compensation for overwork-related CCVDs in Japan.ParticipantsA total of 1215 patients who claimed overwork-related ICH in Japan, of whom 621 had their compensation claim approved (patients with extreme workload) and 622 did not.Primary and secondary outcome measuresLogistic regression analysis was performed to calculate the risk of developing hypertensive ICH in patients with extreme workload compared with those without extreme workload, adjusted for confounders such as age, occupation, smoking status, alcohol consumption and medical history. We also calculated the risk of developing hypertensive ICH in compensated patients by average monthly overtime working hours.ResultsPatients with extreme workloads had a significantly higher odds ratio (OR) for developing hypertensive ICH (1.44, 95% CI: 1.10 to 1.88) than those without extreme workloads. ORs for developing hypertensive ICH according to overtime working hours showed a dose-response relationship; an overtime of 100 hours/month was associated with a significantly higher OR (1.31, 95% CI: 0.89 to 1.91; 1.41, 95% CI: 0.95 to 2.11; and 1.50, 95% CI: 1.01 to 2.22 for 60-79.9, 80-99.9 and≥100 hours/month, respectively) than that for workloads of less than 60 hours/month.ConclusionsRegarding Japanese workers, overtime work could be associated with the risk of developing hypertensive ICH, and hypertension may play an important role in overwork-related ICH.

Project description:Late seizures after intracerebral haemorrhage occur after the initial acute haemorrhagic insult subsides, and represent one of its most feared long-term sequelae. Both susceptibility to late seizures and their functional impact remain poorly characterized. We sought to: (i) compare patients with new-onset late seizures (i.e. delayed seizures), with those who experienced a recurrent late seizure following an immediately post-haemorrhagic seizure; and (ii) investigate the effect of late seizures on long-term functional performance after intracerebral haemorrhage. We performed prospective longitudinal follow-up of consecutive intracerebral haemorrhage survivors presenting to a single tertiary care centre. We tested for association with seizures the following neuroimaging and genetic markers of cerebral small vessel disease: APOE variants ?2/?4, computer tomography-defined white matter disease, magnetic resonance imaging-defined white matter hyperintensities volume and cerebral microbleeds. Cognitive performance was measured using the Modified Telephone Interview for Cognitive Status, and functional performance using structured questionnaires obtained every 6 months. We performed time-to-event analysis using separate Cox models for risk to develop delayed and recurrent seizures, as well as for functional decline risk (mortality, incident dementia, and loss of functional independence) after intracerebral haemorrhage. A total of 872 survivors of intracerebral haemorrhage were enrolled and followed for a median of 3.9 years. Early seizure developed in 86 patients, 42 of whom went on to experience recurrent seizures. Admission Glasgow Coma Scale, increasing haematoma volume and cortical involvement were associated with recurrent seizure risk (all P < 0.01). Recurrent seizures were not associated with long-term functional outcome (P = 0.67). Delayed seizures occurred in 37 patients, corresponding to an estimated incidence of 0.8% per year (95% confidence interval 0.5-1.2%). Factors associated with delayed seizures included cortical involvement on index haemorrhage (hazard ratio 1.63, P = 0.036), pre-haemorrhage dementia (hazard ratio 1.36, P = 0.044), history of multiple prior lobar haemorrhages (hazard ratio 2.50, P = 0.038), exclusively lobar microbleeds (hazard ratio 2.22, P = 0.008) and presence of ? 1 APOE ?4 copies (hazard ratio 1.95, P = 0.020). Delayed seizures were associated with worse long-term functional outcome (hazard ratio 1.83, P = 0.005), but the association was removed by adjusting for neuroimaging and genetic markers of cerebral small vessel disease. Delayed seizures after intracerebral haemorrhage are associated with different risk factors, when compared to recurrent seizures. They are also associated with worse functional outcome, but this finding appears to be related to underlying small vessel disease. Further investigations into the connections between small vessel disease and delayed seizures are warranted.

Project description:Intracerebral haemorrhage causes 1 in 10 strokes, but has the worst overall outcomes of all stroke subtypes. Baseline haematoma volume is a key prognostic factor and early complications - such as haematoma expansion, obstructive hydrocephalus and perihaematomal oedema - may worsen outcome. There is evidence that withdrawal of care may occur more often in intracerebral haemorrhage than ischaemic stroke independent of premorbid health and stroke severity. However, recent evidence shows that reversal of anticoagulants, intensive blood pressure lowering and surgery in carefully selected cases may improve outcomes. Ongoing research may also provide evidence for new medical treatments and minimally invasive approaches to surgery. Effective implementation of evidence-based care to intracerebral haemorrhage patients can be difficult but quality improvement methodology can help to achieve maximal benefit.

Project description:Intracerebral haemorrhage (ICH) accounts for half of the disability-adjusted life years lost due to stroke worldwide. Care pathways for acute stroke result in the rapid identification of ICH, but its acute management can prove challenging because no individual treatment has been shown definitively to improve its outcome. Nonetheless, acute stroke unit care improves outcome after ICH, patients benefit from interventions to prevent complications, acute blood pressure lowering appears safe and might have a modest benefit, and implementing a bundle of high-quality acute care is associated with a greater chance of survival. In this article, we address the important questions that neurologists face in the diagnosis and acute management of ICH, and focus on the supporting evidence and practical delivery for the main acute interventions.

Project description:AimsLittle is known about the performance of the maximally treated intracerebral hemorrhage (max-ICH) score in predicting unfavorable long-term functional outcome and death in patients with intracerebral hemorrhage (ICH) in China. We aimed to validate the performance of the max-ICH score and compared it with other recognized scores.MethodsWe derived data from the China National Stroke Registry (CNSR). Receiver-operating characteristic (ROC) analysis and Hosmer-Lemeshow test were used to measure the score performance. We compared the performance of max-ICH score with six recognized models, including the ICH score, ICH functional outcome score (ICH-FOS), Essen-ICH score, modified intracerebral hemorrhage (MICH) score, intracerebral hemorrhage grading scale (ICH-GS), and functional outcome (FUNC) score.ResultsA total of 2581 patients with spontaneous ICH were enrolled in the study. The max-ICH score was similar or superior to the six existing scores in predicting long-term unfavorable functional outcome after ICH with good discrimination (AUC 0.83, 95% confidence interval [CI] 0.81-0.84) and calibration (Hosmer-Lemeshow P = 0.19). For predicting death, the AUC of max-ICH was 0.81 (95% CI 0.79-0.83).ConclusionsThe easy-to-use max-ICH score is a reliable tool to predict unfavorable long-term (12-month) functional outcome and death after intracerebral hemorrhage in the Chinese population.

Project description:BackgroundOutcome after spontaneous (non-traumatic) intracerebral haemorrhage (ICH) is influenced by haematoma volume; up to one-third of ICHs enlarge within 24 hours of onset. Early haemostatic therapy might improve outcome by limiting haematoma growth. This is an update of a Cochrane Review first published in 2006, and last updated in 2009.ObjectivesTo examine 1) the effectiveness and safety of individual classes of haemostatic therapies, compared against placebo or open control, in adults with acute spontaneous intracerebral haemorrhage, and 2) the effects of each class of haemostatic therapy according to the type of antithrombotic drug taken immediately before ICH onset (i.e. anticoagulant, antiplatelet, or none).Search methodsWe searched the Cochrane Stroke Trials Register, CENTRAL; 2017, Issue 11, MEDLINE Ovid, and Embase Ovid on 27 November 2017. In an effort to identify further published, ongoing, and unpublished randomised controlled trials (RCT), we scanned bibliographies of relevant articles and searched international registers of RCTs in November 2017.Selection criteriaWe sought randomised controlled trials (RCTs) of any haemostatic intervention (i.e. pro-coagulant treatments such as coagulation factors, antifibrinolytic drugs, or platelet transfusion) for acute spontaneous ICH, compared with placebo, open control, or an active comparator, reporting relevant clinical outcome measures.Data collection and analysisTwo authors independently extracted data, assessed risk of bias, and contacted corresponding authors of eligible RCTs for specific data if they were not provided in the published report of an RCT.Main resultsWe included 12 RCTs involving 1732 participants. There were seven RCTs of blood clotting factors versus placebo or open control involving 1480 participants, three RCTs of antifibrinolytic drugs versus placebo or open control involving 57 participants, one RCT of platelet transfusion versus open control involving 190 participants, and one RCT of blood clotting factors versus fresh frozen plasma involving five participants. We were unable to include two eligible RCTs because they presented aggregate data for adults with ICH and other types of intracranial haemorrhage. We identified 10 ongoing RCTs. Across all seven criteria in the 12 included RCTs, the risk of bias was unclear in 37 (44%), high in 16 (19%), and low in 31 (37%). Only one RCT was at low risk of bias in all criteria.In one RCT of platelet transfusion versus open control for acute spontaneous ICH associated with antiplatelet drug use, there was a significant increase in death or dependence (modified Rankin Scale score 4 to 6) at day 90 (70/97 versus 52/93; risk ratio (RR) 1.29, 95% confidence interval (CI) 1.04 to 1.61, one trial, 190 participants, moderate-quality evidence). All findings were non-significant for blood clotting factors versus placebo or open control for acute spontaneous ICH with or without surgery (moderate-quality evidence), for antifibrinolytic drugs versus placebo (moderate-quality evidence) or open control for acute spontaneous ICH (moderate-quality evidence), and for clotting factors versus fresh frozen plasma for acute spontaneous ICH associated with anticoagulant drug use (no evidence).Authors' conclusionsBased on moderate-quality evidence from one trial, platelet transfusion seems hazardous in comparison to standard care for adults with antiplatelet-associated ICH.We were unable to draw firm conclusions about the efficacy and safety of blood clotting factors for acute spontaneous ICH with or without surgery, antifibrinolytic drugs for acute spontaneous ICH, and clotting factors versus fresh frozen plasma for acute spontaneous ICH associated with anticoagulant drug use.Further RCTs are warranted, and we await the results of the 10 ongoing RCTs with interest.

Project description:IntroductionThe role of intracerebral haemorrhage location in haematoma expansion remains unclear. Our objective was to assess the effect of lobar versus non-lobar haemorrhage on haematoma expansion and clinical outcome.Patients and methodsWe analysed data from the prospective PREDICT study where patients with intracerebral haemorrhage presenting to hospital under 6 h of symptom onset received baseline computed tomography (CT), CT angiogram, 24 h follow-up CT, and 90-day mRS. Intracerebral haemorrhage location was categorised as lobar versus non-lobar, and primary outcomes were significant haematoma expansion (>6 ml) and poor clinical outcome (mRS > 3). Multivariable regression was used to adjust for relevant covariates. The primary analysis population was divided by spot sign status and the effect of haemorrhage location was compared to haematoma expansion in exploratory post hoc analysis.ResultsAmong 302 patients meeting the inclusion criteria, lobar haemorrhage was associated with increased haematoma expansion >6 ml (p = 0.003), poor clinical outcome (p = 0.011) and mortality (p = 0.017). When adjusted for covariates, lobar haemorrhage independently predicted significant haematoma expansion (aOR 2.2 (95% CI: 1.1-4.3), p = 0.021) and poor clinical outcome (aOR 2.6 (95% CI: 1.2-5.6), p = 0.019). Post hoc analysis showed that patients who were spot sign negative had a higher degree of haematoma expansion with baseline lobar haemorrhage (lobar 26% versus deep 11%; p = 0.01). No significant associations were observed in spot-positive patients (lobar 52% versus deep 47%; p = 0.69).Discussion and conclusionHaematoma expansion is more likely to occur with lobar intracerebral haemorrhage and haemorrhage location is associated with poor clinical outcome. As expansion is a promising therapeutic target, hemorrhage location may be helpful for prognostication and as a selection tool in future ICH clinical trials.

Project description:Intracerebral haemorrhage accounts for about 10-15% of all strokes and is associated with high mortality and morbidity. No successful phase 3 clinical trials for this disorder have been completed. In the past 6 years, the number of preclinical and clinical studies focused on intracerebral haemorrhage has risen. Important advances have been made in animal models of this disorder and in our understanding of mechanisms underlying brain injury after haemorrhage. Several therapeutic targets have subsequently been identified that are now being pursued in clinical trials. Many clinical trials have been based on limited preclinical data, and guidelines to justify taking preclinical results to the clinic are needed.
