ABSTRACT: Objective
To investigate the radiographic features, temporal evolution, and outcome of patients who develop non-traumatic intracerebral hemorrhage (ICH) while hospitalized for other causes.Methods
We retrospectively reviewed consecutive Emergency Department ICH (ED-ICH) and in-hospital ICH (IH-ICH) over an 8-year period. Variables including demographics, medical history, lab values, lead time to diagnosis, defined as time from last known well to first CT scan, and clinical characteristics, follow-up CT scan, as well as the frequency of withdrawal of life support were compared in the two groups. Mortality in correlation with ICH score was assessed.Results
Sixty-One IH-ICH and 216 ED-ICH patients were compared. History of cardiac disease, cancer, coagulopathy and higher SOFA score at time of diagnosis were significantly higher in the IH-ICH group (all P< 0.01). Time from symptom onset to diagnosis was shorter in the IH-ICH group (median 95 versus 117 minutes, P=0.011). Thirty six percent of IH-ICH fell into a worse ICH category when recalculated 6 hours from initial scan time, compared to only 10% of the ED-ICH. ICH score was well calibrated in ED-ICH when assessed both at diagnosis and 6 hours later, but underestimated actual mortality in the IH-ICH, particularly at ICH scores 0 to 3. End of life measures were pursued in 69% of IH-ICH group compared to 19% in the ED-ICH group.Conclusions
IH-ICH, is associated with higher overall mortality rates and often times heralds withdrawal of life sustaining therapies in patients. In addition, IH-ICH in comparison to ED-ICH, significantly changes in severity metrics within the first 6 hours. ICH score is not accurate and not calibrated to reflect reasonable stratification of mortality in IH-ICH. Prospective validation and investigation of variables accounting for higher IH-ICH mortality are needed.

Project description:Background Non-traumatic intracerebral hemorrhage (ICH) accounts for 10–15% of all strokes and leads to a higher rate of mortality as compared to ischemic strokes. We aimed to find out whether the thrombin generation assay (TGA) could predict outcomes in patients with ICH. Patients and methods In this prospective, observational study, 87 consecutive patients with ICH and 164 healthy controls were included. Computed tomography (CT), detailed clinical investigation, and laboratory investigations were performed from patients on admission. TGA was performed using stored platelet poor plasma obtained on admission. Lag time, endogen thrombin potential (ETP), peak thrombin, and time to peak parameters were calculated. Short- and long-term outcomes of ICH were defined at 14 days and 3 months post-event according to the NIHSS and the modified Rankin Scale (mRS), respectively. Results Peak thrombin was significantly higher in patients as compared to controls (397.2 ± 93.9 vs. 306 ± 85.3 nM, p < 0.0001). Lag time, ETP, and time to peak parameters showed a significant positive correlation with CRP in both groups. In patients with worse long-term functional outcomes, peak thrombin was significantly higher as compared to those with favorable outcomes [mRS 2–6 median: 402.5 (IQR:344.8–473.8) vs. mRS 0–1: 326.4 (294.2–416.1) nM, p = 0.0096]. Based on the statistically optimal threshold of 339.1 nM peak thrombin, the sensitivity and specificity of this parameter to determine mRS 2–6 as an outcome were 80.8 and 64.7%, respectively. In a binary logistic regression model including age, sex, BMI, smoking status, NIHSS on admission, D-dimer, and peak thrombin (>339.1 nM), only NIHSS and the peak thrombin parameters remained in the model as significant, independent predictors of poor outcome. Lag time and time to peak showed a modest, significant negative correlation with intracerebral bleeding volume on admission (r = −0.2603, p = 0.0231 and r = −0.3698, p = 0.0010, respectively). During the follow-up of patients, estimated hemorrhage volumes on day 90 showed significant positive association with the ETP and peak thrombin parameters (r = 0.3838, p = 0.0363 and r = 0.5383, p = 0.0021, respectively). Conclusion In patients with ICH, TG was increased as compared to healthy controls, which might be explained by the presence of higher inflammatory parameters in patients. Peak thrombin measured on admission might be a useful tool to predict outcomes in patients with ICH.

Project description:ImportanceAlthough the use of factor Xa (FXa) inhibitors has increased substantially over the past decade, there are limited data on characteristics and outcomes of FXa inhibitor-associated intracerebral hemorrhage (ICH).ObjectiveTo investigate the association between prior oral anticoagulant use (FXa inhibitors, warfarin, or none) and in-hospital outcomes among patients with nontraumatic ICH.Design, setting, and participantsThis is a cohort study of 219 701 patients with nontraumatic ICH admitted to 1870 hospitals in the Get With The Guidelines-Stroke registry between October 2013 and May 2018. Data analysis was performed in December 2019.ExposuresAnticoagulation therapy before ICH.Main outcomes and measuresThe primary outcome was in-hospital mortality. Secondary outcomes were a composite measure of in-hospital mortality or discharge to hospice, discharge home, independent ambulation, and modified Rankin Scale (mRS) score at discharge.ResultsOf 219 701 patients (mean [SD] age, 68.2 [15.3] years; 104 940 women [47.8%]), 9202 (4.2%) were taking FXa inhibitors, 21 430 (9.8%) were taking warfarin, and 189 069 (86.0%) were not taking any oral anticoagulant before ICH. Patients taking FXa inhibitors or warfarin were older and had higher prevalence of cardiovascular risk factors. Compared with those not taking an oral anticoagulant (42 660 of 189 069 patients [22.6%]), the in-hospital mortality risk was higher for both FXa inhibitors (2487 of 9202 patients [27.0%]; adjusted odds ratio [aOR], 1.27; 95% CI, 1.20-1.34; P < .001) and warfarin (7032 of 21 430 patients [32.8%]; aOR, 1.67; 95% CI, 1.60-1.74; P < .001). Both FXa inhibitors (3478 of 9202 patients [37.8%]; aOR, 1.19; 95% CI, 1.13-1.26; P < .001) and warfarin (9151 of 21 430 patients [42.7%]; aOR, 1.50; 95% CI, 1.44-1.56; P < .001) were associated with higher odds of death or discharge to hospice compared with not taking oral anticoagulation (58 022 of 189 069 patients [30.7%]). Although the rates of discharge home, independent ambulation, mRS scores of 0 or 1, and mRS scores of 0 to 2 were numerically lower among patients taking FXa inhibitors, these differences were not significant compared with patients not taking oral anticoagulants. In contrast, patients taking FXa inhibitors were less likely to die (aOR, 0.76; 95% CI, 0.72-0.81; P < .001) or to experience death or discharge to hospice (aOR, 0.79; 95% CI, 0.75-0.84; P < .001), more likely to be discharged home (aOR, 1.18; 95% CI, 1.10-1.26; P < .001), and had better mRS scores at discharge (eg, mRS scores of 0-1: aOR, 1.24; 95% CI, 1.09-1.40; P < .001) than those treated with warfarin. Concomitant warfarin and antiplatelet therapy (either single or dual) was associated with worse outcomes compared with taking warfarin alone (eg, in-hospital mortality for dual-antiplatelet agents: aOR, 2.07; 95% CI, 1.72-2.50; P < .001). However, such incremental risk was not significant in patients taking FXa inhibitors.Conclusions and relevanceIn this cohort study, FXa inhibitor-associated ICH was associated with higher risk of mortality or death or discharge to hospice than not taking an oral anticoagulant, but patients taking FXa inhibitors had better outcomes than those with warfarin-related ICH.

Project description:Background: Non-traumatic intracerebral hemorrhage (ICH) accounts for 10-15% of all strokes and results in a higher rate of mortality as compared to ischemic strokes. In the IRONHEART study, we aimed to find out whether a modified in vitro clot lysis assay method, that includes the effect of neutrophil extracellular traps (NETs) might predict ICH outcomes. Patients and Methods: In this prospective, observational study, 89 consecutive non-traumatic ICH patients were enrolled. Exclusion criteria included aneurysm rupture, cancer, liver- or kidney failure or hemorrhagic diathesis. On admission, detailed clinical and laboratory investigations were performed. ICH volume was estimated based on CT performed on admission, day 14 and 90. A conventional in vitro clot lysis assay (CLA) and a modified CLA (mCLA) including cell-free-DNA and histones were performed from stored platelet-free plasma taken on admission. Clot formation and lysis in case of both assays were defined using the following variables calculated from the turbidimetric curves: maximum absorbance, time to maximum absorbance, clot lysis times (CLT) and area under the curve (CLA AUC). Long-term ICH outcomes were defined 90 days post-event by the modified Rankin Scale (mRS). All patients or relatives provided written informed consent. Results: Patients with more severe stroke (NIHSS>10) presented significantly shorter clot lysis times of the mCLA in the presence of DNA and histone as compared to patients with milder stroke [10%CLT: NIHSS 0-10: median 31.5 (IQR: 21.0-40.0) min vs. NIHSS>10: 24 (18-31.0) min, p = 0.032]. Shorter clot lysis times of the mCLA showed significant association with non-survival by day 14 and with unfavorable long-term outcomes [mRS 0-1: 36.0 (22.5.0-51.0) min; mRS 2-5: 23.5 (18.0-36.0) min and mRS 6: 22.5 (18.0-30.5) min, p = 0.027]. Estimated ICH volume showed significant negative correlation with mCLA parameters, including 10%CLT (r = -0.3050, p = 0.009). ROC analysis proved good diagnostic performance of mCLA for predicting poor long-term outcomes [AUC: 0.73 (0.57-0.89)]. In a Kaplan-Meier survival analysis, those patients who presented with an mCLA 10%CLT result of >38.5 min on admission showed significantly better survival as compared to those with shorter clot lysis results (p=0.010). Conclusion: Parameters of mCLA correlate with ICH bleeding volume and might be useful to predict ICH outcomes.

Project description:Background and purposeKnowledge about different etiologies of non-traumatic intracerebral hemorrhage (ICH) and their outcomes is scarce.MethodsWe assessed prevalence of pre-specified ICH etiologies and their association with outcomes in consecutive ICH patients enrolled in the prospective Swiss Stroke Registry (2014 to 2019).ResultsWe included 2,650 patients (mean±standard deviation age 72±14 years, 46.5% female, median National Institutes of Health Stroke Scale 8 [interquartile range, 3 to 15]). Etiology was as follows: hypertension, 1,238 (46.7%); unknown, 566 (21.4%); antithrombotic therapy, 227 (8.6%); cerebral amyloid angiopathy (CAA), 217 (8.2%); macrovascular cause, 128 (4.8%); other determined etiology, 274 patients (10.3%). At 3 months, 880 patients (33.2%) were functionally independent and 664 had died (25.1%). ICH due to hypertension had a higher odds of functional independence (adjusted odds ratio [aOR], 1.33; 95% confidence interval [CI], 1.00 to 1.77; P=0.05) and lower mortality (aOR, 0.64; 95% CI, 0.47 to 0.86; P=0.003). ICH due to antithrombotic therapy had higher mortality (aOR, 1.62; 95% CI, 1.01 to 2.61; P=0.045). Within 3 months, 4.2% of patients had cerebrovascular events. The rate of ischemic stroke was higher than that of recurrent ICH in all etiologies but CAA and unknown etiology. CAA had high odds of recurrent ICH (aOR, 3.38; 95% CI, 1.48 to 7.69; P=0.004) while the odds was lower in ICH due to hypertension (aOR, 0.42; 95% CI, 0.19 to 0.93; P=0.031).ConclusionsAlthough hypertension is the leading etiology of ICH, other etiologies are frequent. One-third of ICH patients are functionally independent at 3 months. Except for patients with presumed CAA, the risk of ischemic stroke within 3 months of ICH was higher than the risk of recurrent hemorrhage.

Project description:Background and purposeStatin use may be associated with improved outcome in intracerebral hemorrhage patients. However, the topic remains controversial. Our analysis examined the effect of prior, continued, or new statin use on intracerebral hemorrhage outcomes using the ERICH (Ethnic/Racial Variations of Intracerebral Hemorrhage) data set.MethodsWe analyzed ERICH (a multicenter study designed to examine ethnic variations in the risk, presentation, and outcomes of intracerebral hemorrhage) to explore the association of statin use and hematoma growth, mortality, and 3-month disability. We computed subset analyses with respect to 3 statin categories (prior, continued, or new use).ResultsTwo thousand four hundred and fifty-seven enrolled cases (mean age, 62 years; 42% females) had complete data on mortality and 3-month disability (modified Rankin Scale). Among those, 1093 cases were on statins (prior, n=268; continued, n=423; new, n=402). Overall, statin use was associated with reduced mortality and disability without any effect on hematoma growth. This association was primarily driven by continued/new statin use. A multivariate analysis adjusted for age and major predictors for poor outcome showed that continued/new statins users had good outcomes compared with prior users. However, statins may have been continued/started more frequently among less severe patients. When a propensity score was developed based on factors that could influence a physician's decision in prescribing statins and used as a covariate, continued/new statin use was no longer a significant predictor of good outcome.ConclusionsAlthough statin use, especially continued/new use, was associated with improved intracerebral hemorrhage outcomes, this effect may merely reflect the physician's view of a patient's prognosis rather than a predictor of survival.

Project description:PurposeThe aim of this study was to investigate the temporal evolution of perihematomal blood-brain barrier (BBB) compromise and edema growth and to determine the role of BBB compromise in edema growth.MethodsSpontaneous intracerebral hemorrhage patients who underwent computed tomography perfusion (CTP) were divided into five groups according to the time interval from symptom onset to CTP examination. Permeability-surface area product (PS) maps were generated using CTP source images. Ipsilateral and contralateral mean PS values were computed in the perihematomal and contralateral mirror regions. The relative PS (rPS) value was calculated as a ratio of ipsilateral to contralateral PS value. Hematoma and perihematomal edema volume were determined on non-contrast CT images.ResultsIn the total of 101 intracerebral hemorrhage patients, the ipsilateral mean PS value was significantly higher than that in contralateral region (z = -8.284, p < 0.001). The perihematomal BBB permeability showed a course of dynamic changes including an increase in the hyperacute and acute phases, a decrease in the early subacute phase and a second increase in the late subacute phase and chronic phase. Perihematomal edema increased gradually until the late subacute phase and then slightly increased. There was a relationship between rPS value and edema volume (β = 0.254, p = 0.006).ConclusionThe perihematomal BBB permeability is dynamic changes, and edema growth is gradually increased in patients following intracerebral hemorrhage. BBB compromise plays an essential role in edema growth. The quantitative assessment of BBB compromise may provide valuable information in therapeutic interventions of intracerebral hemorrhage patients.

Project description:Background and Purpose- We investigated the prognostic significance of spontaneous intracerebral hemorrhage location in presence of severe intraventricular hemorrhage. Methods- We analyzed diagnostic computed tomography scans from 467/500 (excluding primary intraventricular hemorrhage) subjects from the CLEAR (Clot Lysis: Evaluating Accelerated Resolution of Intraventricular Hemorrhage) III trial. We measured intracerebral hemorrhage engagement with specific anatomic regions, and estimated association of each region with blinded assessment of dichotomized poor stroke outcomes: mortality, modified Rankin Scale score of 4 to 6, National Institutes of Health Stroke Scale score of >4, stroke impact scale score of <60, Barthel Index <86, and EuroQol visual analogue scale score of <50 and <70 at days 30 and 180, respectively, using logistic regression models. Results- Frequency of anatomic region involvement consisted of thalamus (332 lesions, 71.1% of subjects), caudate (219, 46.9%), posterior limb internal capsule (188, 40.3%), globus pallidus/putamen (127, 27.2%), anterior limb internal capsule (108, 23.1%), and lobar (29, 6.2%). Thalamic location was independently associated with mortality (days 30 and 180) and with poor outcomes on most stroke scales at day 180 on adjusted analysis. Posterior limb internal capsule and globus pallidus/putamen involvement was associated with increased odds of worse disability at days 30 and 180. Anterior limb internal capsule and caudate locations were associated with decreased mortality on days 30 and 180. Anterior limb internal capsule lesions were associated with decreased long-term morbidity. Conclusions- Acute intracerebral hemorrhage lesion topography provides important insights into anatomic correlates of mortality and functional outcomes even in severe intraventricular hemorrhage causing obstructive hydrocephalus. Models accounting for intracerebral hemorrhage location in addition to volumes may improve outcome prediction and permit stratification of benefit from aggressive acute interventions.

Project description:IntroductionThe impact of anemia on functional outcome and mortality in patients suffering from non-traumatic intracerebral hemorrhage (ICH) has not been investigated. Here, we assessed the relationship between hemoglobin (HB) levels and clinical outcome after ICH.MethodsOne hundred and ninety six patients suffering from supratentorial, non-traumatic ICH were extracted from our local stroke database (June 2004 to June 2006). Clinical and radiologic computed tomography data, HB levels on admission, mean HB values and nadir during hospital stay were recorded. Outcome was assessed at discharge and 3 months using the modified Rankin score (mRS).ResultsForty six (23.5%) patients achieved a favorable functional outcome (mRS <or= 3) and 150 (76.5%) had poor outcome (mRS 4 - 6) at discharge. Patients with poor functional outcome had a lower mean HB (12.3 versus 13.7 g/dl, P < 0.001) and nadir HB (11.5 versus 13.0 g/dl, P < 0.001). Ten patients (5.1%) received red blood cell (RBC) transfusions. In a multivariate logistic regression model, the mean HB was an independent predictor for poor functional outcome at three months (odds ratio (OR) 0.73, 95% confidence interval (CI) 0.58-0.92, P = 0.007), along with National Institute of Health Stroke Scale (NIHSS) at admission (OR 1.17, 95% CI 1.11 - 1.24, P < 0.001), and age (OR 1.08, 95% CI 1.04 - 1.12, P < 0.001).ConclusionsWe report an association between low HB and poor outcome in patients with non-traumatic, supratentorial ICH. While a causal relationship could not be proven, previous experimental studies and studies in brain injured patients provide evidence for detrimental effects of anemia on brain metabolism. However, the potential risk of anemia must be balanced against the risk of harm from red blood cell infusion.

Project description:BackgroundTo identify whether the risk of intracerebral hemorrhage is higher in patients with coronavirus disease 2019 (COVID-19), we compared the risk factors, comorbidities, and outcomes in patients intracerebral hemorrhage and COVID-19 and those without COVID-19.MethodsWe analyzed the data from the Cerner deidentified COVID-19 data set derived from 62 health care facilities. The data set included patients with an emergency department or inpatient encounter with discharge diagnoses codes that could be associated with suspicion of or exposure to COVID-19 or confirmed COVID-19.ResultsThere were a total of 154 (0.2%) and 667 (0.3%) patients with intracerebral hemorrhage among 85,645 patients with COVID-19 and 197,073 patients without COVID-19, respectively. In the multivariate model, there was a lower risk of intracerebral hemorrhage in patients with COVID-19 (odds ratio 0.5; 95% confidence interval 0.5-0.6; p < .0001) after adjustment for sex, age strata, race/ethnicity, hypertension, diabetes mellitus, nicotine dependence/tobacco use, hyperlipidemia, atrial fibrillation, congestive heart failure, long-term anticoagulant use, and alcohol abuse. The proportions of patients who developed pneumonia (58.4% versus 22.5%; p < .0001), acute kidney injury (48.7% versus 31.0%; p < .0001), acute myocardial infarction (11% versus 6.4%; p = .048), sepsis (41.6% versus 22.5%; p < .0001), and respiratory failure (61.7% versus 42.3%; p < .0001) were significantly higher among patients with intracerebral hemorrhage and COVID-19 compared with those without COVID-19. The in-hospital mortality among patients with intracerebral hemorrhage and COVID-19 was significantly higher compared with that among those without COVID-19 (40.3% versus 19.0%; p < .0001).ConclusionsOur analysis does not suggest that rates of intracerebral hemorrhage are higher in patients with COVID-19. The higher mortality in patients with intracerebral hemorrhage and COVID-19 compared with those without COVID-19 is likely mediated by higher frequency of comorbidities and adverse in-hospital events.

Project description:Methamphetamine use has emerged as a risk factor for intracerebral hemorrhage (ICH). We aim to investigate the clinical characteristics and outcomes of methamphetamine-associated ICH (Meth-ICH) versus Non-Meth-ICH. Patients with ICH between January 2011 and December 2017 were studied. Meth-ICH and Non-Meth-ICH were defined by history of abuse and urine drug screen (UDS). The clinical features of the 2 groups were explored. Among the 677 consecutive patients, 61 (9.0%) were identified as Meth-ICH and 350 as Non-Meth ICH. Meth-ICH was more common in Hispanics (14.6%) and Whites (10.1%) as compared to Asians (1.2%). Patients with Meth-ICH were more often younger (51.2 vs. 62.2 years, p?<?0.001), male (77.0% vs. 61.4.0%, p?<?0.05), and smokers (44.3% vs. 13.4%, p?<?0.001). Non-Meth-ICH was more likely to have history of hypertension (72.61% v. 59%, p?<?0.05) or antithrombotic use (10.9% vs. 1.6%, p?<?0.05). There was no significant difference in clinical severity, hospital length of stay (LOS), rate of functional independence (29.5% vs. 25.7%, p?=?0.534), or mortality (18.0% vs. 24.6%, p?=?0.267) between the 2 groups. Methamphetamine use was not an independent predictor of poor outcome. Despite difference in demographics, Meth-ICH is similar to Non-Meth ICH in hospital course and outcome.
