Abstract
Spontaneous intracerebral hemorrhage (ICH) is the most morbid of all stroke types with a high early mortality and significant early disability burden. Traditionally, outcome assessments after ICH have mirrored those of acute ischemic stroke, with 3 months post-ICH being considered a standard time point in most clinical trials, observational studies, and clinical practice. At this time point, the majority of ICH survivors remain with moderate to severe functional disability. However, emerging data suggest that recovery after ICH occurs over a more protracted course and requires longer periods of follow-up, with more than 40% of ICH survivors with initial severe disability improving to partial or complete functional independence over 1 year. Multiple other domains of recovery impact ICH survivors including cognition, mood, and health-related quality of life, all of which remain under studied in ICH. To further complicate the picture, the most important driver of mortality after ICH is early withdrawal of life-sustaining therapies, before initiation of treatment and evaluating effects of prolonged supportive care, influenced by early pessimistic prognostication based on baseline severity factors and prognostication biases. Thus, our understanding of the true natural history of ICH recovery remains limited. This review summarizes the existing literature on outcome trajectories in functional and nonfunctional domains, describes limitations in current prognostication practices, and highlights areas of uncertainty that warrant further research.

Leveraging the Capabilities of AI: Novice Neurology-Trained Operators Performing Cardiac POCUS in Patients with Acute Brain Injury. Neurocrit Care 2024:10.1007/s12028-024-01953-z. [PMID: 38506968 DOI: 10.1007/s12028-024-01953-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Accepted: 02/01/2024] [Indexed: 03/22/2024]
Abstract
BACKGROUND Cardiac point-of-care ultrasound (cPOCUS) can aid in the diagnosis and treatment of cardiac disorders. Such disorders can arise as complications of acute brain injury, but most neurologic intensive care unit (NICU) providers do not receive formal training in cPOCUS. Caption artificial intelligence (AI) uses a novel deep learning (DL) algorithm to guide novice cPOCUS users in obtaining diagnostic-quality cardiac images. The primary objective of this study was to determine how often NICU providers with minimal cPOCUS experience capture quality images using DL-guided cPOCUS as well as the association between DL-guided cPOCUS and change in management and time to formal echocardiograms in the NICU. METHODS From September 2020 to November 2021, neurology-trained physician assistants, residents, and fellows used DL software to perform clinically indicated cPOCUS scans in an academic tertiary NICU. Certified echocardiographers evaluated each scan independently to assess the quality of images and global interpretability of left ventricular function, right ventricular function, inferior vena cava size, and presence of pericardial effusion. Descriptive statistics with exact confidence intervals were used to calculate proportions of obtained images that were of adequate quality and that changed management. Time to first adequate cardiac images (either cPOCUS or formal echocardiography) was compared using a similar population from 2018. RESULTS In 153 patients, 184 scans were performed for a total of 943 image views. Three certified echocardiographers deemed 63.4% of scans as interpretable for a qualitative assessment of left ventricular size and function, 52.6% of scans as interpretable for right ventricular size and function, 34.8% of scans as interpretable for inferior vena cava size and variability, and 47.2% of scans as interpretable for the presence of pericardial effusion. Thirty-seven percent of screening scans changed management, most commonly adjusting fluid goals (81.2%). Time to first adequate cardiac images decreased significantly from 3.1 to 1.7 days (p < 0.001). CONCLUSIONS With DL guidance, neurology providers with minimal to no cPOCUS training were often able to obtain diagnostic-quality cardiac images, which informed management changes and significantly decreased time to cardiac imaging.

Abstract
OBJECTIVES To examine the proportions of unemployment, decreased household income, and newly acquired disability, and their impact on long-term mortality after intensive care unit (ICU) admission due to nontraumatic intracranial hemorrhage (IH). MATERIALS AND METHODS This nationwide population-based retrospective cohort study enrolled adult patients admitted to the ICU because of nontraumatic IH between 2010 and 2018 in South Korea. Patients who were alive ≥365 days after ICU admission were defined as nontraumatic IH survivors. RESULTS In total, 104,086 nontraumatic IH survivors were included in the final analysis. Among them, 7,225 (6.9 %) experienced job loss, 25,709 (24.7 %) experienced decreased household income, and 20,938 (20.1 %) had newly acquired disabilities, of whom 14,188 (13.6 %) had newly acquired brain disabilities. Male sex, increased duration of intensive care unit stay, comorbid status, hospital admission through the emergency room, nontraumatic intracerebral hemorrhage, receipt of surgery, mechanical ventilatory support, and increased total cost of hospitalization were associated with job loss, decreased household income, and newly acquired disabilities. However, these changes were not significantly associated with 2-year all-cause mortality (adjusted hazard ratio: 1.00, 95 % confidence interval: 0.95, 1.06; P = 0.997). CONCLUSIONS Many nontraumatic IH survivors experienced unemployment, decreased household income, and newly acquired disability one year after ICU admission in South Korea. Some factors were potential risk factors for these changes, but the changes were not associated with 2-year all-cause mortality.

Abstract
Elevated pulse pressure is commonly observed in cardiovascular diseases and serves as an independent risk factor and predictor of cardiac mortality. However, the role of pulse pressure in patients with spontaneous intracerebral hemorrhage (ICH) remains uncertain. This study aimed to investigate the association between admission pulse pressure and clinical characteristics, including in-hospital outcomes, in ICH patients. We retrospectively analyzed the data of 292 ICH patients, categorizing them into two groups based on admission wide pulse pressure: > 100 mmHg (n = 60) and ≤ 100 mmHg (n = 232). Clinical characteristics and in-hospital outcomes were compared between the groups, and multivariate logistic regression was performed to identify independent factors. Patients with wide pulse pressure were older, had lower Glasgow Coma Scale, larger intraparenchymal hematomas, more pronounced midline shifts, and higher rates of intraventricular hematoma extension and hydrocephalus. These patients also experienced higher frequencies of craniotomy or craniectomy and longer hospital stays. Multivariate logistic regression revealed that pulse pressure > 100 mmHg was significantly associated with increased in-hospital mortality (odds ratio 4.31, 95% confidence interval 1.12-16.62, p = 0.03), but not with a modified Rankin Scale score of 4-6. In conclusion, our investigation demonstrates a significant relationship between admission pulse pressure and severe clinical characteristics in ICH patients. Importantly, a wider pulse pressure is linked to heightened in-hospital mortality. These results underscore the necessity for customized strategies to predict patient outcomes in this population. Further research is essential to explore potential therapeutic interventions targeting pulse pressure to improve clinical outcomes for ICH patients.

J Clin Med 2023; 12:6608. [PMID: 37892746 PMCID: PMC10607334 DOI: 10.3390/jcm12206608] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2023] [Revised: 10/14/2023] [Accepted: 10/17/2023] [Indexed: 10/29/2023] Open
Abstract
BACKGROUND The neuroprotective effect of statins has become a focus of interest in spontaneous intracerebral hemorrhage (sICH). The purpose of this study was: (1) to evaluate the effect of statin use by the analyzed patients with sICH in the period preceding the onset of hemorrhage on their baseline neurological status and baseline neuroimaging of the head; (2) to evaluate the effect of statin use in the acute period of hemorrhage on the course and prognosis in the in-hospital period, taking into account whether the statin was taken before the hemorrhage or only after its onset; (3) to evaluate the effect of continuing statin treatment after in-hospital treatment on the functional performance and survival of patients up to 90 days after the onset of sICH symptoms, taking into account whether the statin was taken before the onset of sICH. MATERIAL AND METHODS A total of 153 patients diagnosed with sICH were analyzed, where group I were not previously taking a statin and group II were taking a statin before sICH onset. After lipidogram assessment, group I was divided into patients without dyslipidemia and without statin treatment (Ia) and patients with dyslipidemia who received de novo statin treatment during hospitalization (Ib). Group II patients continued taking statin therapy. We evaluated the effect of prior statin use on the severity of hemorrhage; the effect of statin use during the acute period of sICH on its in-hospital course; and the effect of statin treatment on the severity of neurological deficit, functional capacity and survival of patients up to 90 days after the onset of sICH symptoms. RESULTS There was no effect of prior statin use on the severity of hemorrhage as assessed clinically and by neuroimaging of the head. At in-hospital follow-up, subgroup Ia was the least favorable in terms of National Institutes of Health Stroke Scale (NIHSS) score. This subgroup had the highest percentage of deaths during hospitalization. In the post-hospital period, the greatest number of patients with improvement in the NIHSS, modified Rankin Scale (mRS) and Barthel scales were among those taking statins, especially group II patients. At 90-day follow-up, survival analysis fell significantly in favor of subgroup Ib and group II. CONCLUSIONS 1. The use of statins in the pre-sICH period did not adversely affect the patients' baseline neurological status or the results of baseline neuroimaging studies. 2. Continued statin therapy prior to the onset of sICH or the inclusion of statins in acute treatment in patients with sICH and dyslipidemia does not worsen the course of the disease and the in-hospital prognosis. Statin therapy should not be discontinued during the acute phase of sICH. 3. To conclude the eventual beneficial effect on the functional performance and survival of patients after sICH onset, comparability of the analyzed groups in terms of clinical, radiological and other prognostic factors in spontaneous intracerebral hemorrhage would be needed. Future studies are needed to confirm these findings.

Abstract
BACKGROUND The association between white blood cell (WBC) counts and mortality in patients with intracerebral hemorrhage (ICH) has not been established. The aim of this study is to determine whether higher WBC is associated with mortality at 90 days. METHODS A retrospective observational study was conducted at two medical hospitals in China. Baseline WBC count on admission served as the primary predictor variable. Longitudinal WBC counts within the first week after admission were collected to assess the effects of WBC trajectory and the median and maximum WBC counts on outcomes following ICH. Associations of WBC count with outcomes were evaluated in multivariable regression analyses. RESULTS We identified 3613 patients with ICH who met the inclusion criteria. After adjusting primary confounding variables, patients with increased WBC count had a significantly higher risk of 90-day mortality (p < 0.001 for trend). In the receiver operating characteristic analyses, the capacity for all-cause mortality prediction by WBC count on admission (area under the ROC curve (AUC) = 0.65) was superior to other important inflammatory markers, including neutrophil (AUC = 0.64) , lymphocyte (AUC = 0.57), albumin (AUC = 0.57), and platelet count (AUC = 0.53), p < 0.001 for WBC vs. neutrophil, and the median WBC count (AUC = 0.66) within the first week after admission was a better marker than admission WBC count (p = 0.02). CONCLUSIONS In patients with ICH, WBC count on admission was associated with all-cause mortality at 90 days. Additionally, the median and maximum WBC counts within the first week after admission showed better predictive ability for the 90-day mortality compared with the WBC count on admission.

Abstract
Multinomial logistic regression (MLR) is often used to model the association between a nominal outcome variable and one or more covariates. The results of MLR are interpreted as relative risk ratios (RRR) and warrant a more coherent interpretation than ordinary logistic regression. Some authors compare the results of MLR to ordinal logistic regression (OLR), irrespective of the fact that these estimate different quantities. We aim to investigate the time trends in the use and misuse of MLR in studies including stroke patients, specifically the extent to which (1) the results are denoted as anything other than RRR, (2) comparisons are made of results with results of OLR and (3) results have been interpreted coherently. Secondarily, we examine the use of model validation techniques in studies with predictive aims. We searched EMBASE and PubMed for articles using MLR on populations of stroke patients. Identified studies were screened, and information pertaining to our aims was extracted. A total of 285 articles were identified through a systematic literature search, and 68 of these were included in the review. Of these, 60 articles (88%) did not denote exponentiated coefficients of MLR as relative risk ratios but rather some other measure. Additionally, 63 articles (93%) interpreted the results of MLR in a non-coherent manner. Two articles attempted to compare MLR results with those of OLR. Nine studies attempted to use MLR for predictive means, and three used relevant validation techniques. From these findings, it is clear that the interpretation of MLR is often suboptimal.

Abstract
Differences exist between genders in intracerebral hemorrhage cause, epidemiology, and outcomes. These gender differences are in part attributable to physiologic differences; however, demographic, social/behavioral risk factors, along with health care system variation and potential family and/or clinician bias play a role as well. These factors vary from region to region and interact, making comprehensive and definitive conclusions regarding sex differences a challenging task. Differences between the genders in intracerebral hemorrhage epidemiology and extensive differences in underlying pathophysiology, intervention, risk factors, and outcome are all discussed.

Abstract
OBJECTIVE This study aims to evaluate the prognostic value of blood-based biomarkers and their combinations, in particular the glucose-albumin ratio (GAR), in patients with spontaneous intracerebral hemorrhage (ICH). METHODS A retrospective observational study on 2481 patients from one hospital was conducted and validated with 602 patients from another. We assessed 15 biomarkers and focused on GAR to elucidate its prognostic and predictive value for outcomes in both cohorts. The primary outcome was mortality at 90 days. RESULTS The ratio of glucose-to-albumin, defined as GAR, was superior to other biomarkers for predicting mortality at 90 days in patients with ICH (AUC = 0.72). High GAR (using the best cutoff value of 0.19) was associated with increased mortality at 90 days (odds ratios of 1.90, 95% CI 1.54-2.34) and all-cause mortality in the first 3 years after admission (hazard ratio of 1.62, 95% CI 1.42-1.86). All aforementioned findings for GAR were successfully validated in an external independent cohort. CONCLUSIONS GAR may be a valuable biomarker for predicting the mortality of patients with ICH.

Abstract
BACKGROUND Intracerebral haemorrhage (ICH) has high mortality in the acute phase and poor functional outcome in the majority of survivors. ICH recurrence is a major determinant of long-term prognosis and is the most feared complication of antithrombotic treatment. On the other hand, ICH patients are at high risk of future ischaemic vascular events. METHODS This narrative review provides a critical analysis of the current knowledge on the topic. We performed a Pubmed search with the following terms 'intracerebral haemorrhage', 'stroke', 'outcome', 'secondary prevention', 'anticoagulation' and 'atrial fibrillation', including only English written studies with no time restrictions. RESULTS Blood pressure management is the cornerstone of secondary ICH prevention, regardless of ICH location or underlying cerebral small vessel disease. Resumption of antiplatelet and anticoagulation therapy is often challenging, with limited evidence from randomized trials. Clinical and imaging predictors can inform the stratification of ICH recurrence risk and might identify patients at very high probability of future haemorrhagic events. This narrative review provides a summary of the main diagnostic tools and therapeutic strategies available for secondary prevention in ICH survivors. CONCLUSION Appropriate recognition and treatment of modifiable risk factors for ICH recurrence might improve outcomes in ICH survivors. Ongoing randomized trials might provide novel insights and improve long-term management.

Abstract
Background The association between cancer types and specific bleeding events in patients with atrial fibrillation has been scarcely investigated. Also, the performance of bleeding risk scores in this high-risk subgroup of patients is unclear. We investigated the rate of any bleeding, intracranial hemorrhage, major bleeding, and gastrointestinal bleeding according to cancer types in patients with atrial fibrillation. We also tested the predictive value of HAS-BLED, ATRIA, and ORBIT bleeding risk scores. Methods and Results Observational retrospective cohort study including hospitalized patients with atrial fibrillation and cancer from the French National Hospital Discharge Database (Programme de Medicalisation des Systemes d'Information) from January 2010 to December 2019. Major bleeding was defined according to Bleeding Academic Research Consortium definitions. Patients with HAS-BLED ≥3, ATRIA ≥5, or ORBIT ≥4 were classified as at high bleeding risk. Receiver operating characteristic analysis for each score against any bleeding, major bleeding, gastrointestinal bleeding, and intracranial hemorrhage was performed. Areas under the curve (AUCs) were then compared. We included 399 344 patients. Mean age was 77.9±10.2 years, and 63.2% were men. The highest intracranial hemorrhage rates were found in leukemia (1.89%/year), myeloma (1.52%/year), lymphoma and liver (1.45%/year), and pancreas cancer (1.41%/year). Receiver operating characteristic analysis showed that ORBIT score predicted best for any bleeding. In addition, ORBIT score ≥4 had the highest predictivity for major bleeding (AUC, 0.805), followed by HAS-BLED ≥3 and ATRIA ≥5 (AUCs, 0.716 and 0.700, respectively). HAS-BLED and ORBIT performed best for intracranial hemorrhage (AUCs, 0.744 and 0.742 for continuous scores, respectively), better than ATRIA (AUC, 0.635). For gastrointestinal bleeding, ORBIT ≥4 had the highest predictivity (AUC, 0.756), followed by the HAS-BLED ≥3 (AUC, 0.702) and ATRIA ≥5 (AUC, 0.662). Conclusions Some cancer types carry a greater bleeding risk in patients with atrial fibrillation. The identification and management of modifiable bleeding risk factors is crucial in these patients, as well as to flag up high bleeding risk patients for early review and follow-up.

Abstract
IMPORTANCE Patients with stroke due to nontraumatic (spontaneous) intracerebral hemorrhage (ICH) often harbor vascular risk factors and comorbidities, but it is unclear which major adverse cardiovascular events (MACEs) occur more frequently among patients with a prior ICH than the general population. OBJECTIVE To evaluate the risk of a MACE for patients with a prior ICH compared with the general population. DESIGN, SETTING, AND PARTICIPANTS This cohort study identified 8991 patients with a first ICH in the Danish Stroke Registry from January 1, 2005, to June 30, 2018, who were aged 45 years or older and survived more than 30 days after an ICH. Patients in this ICH cohort were matched 1:40 on age, sex, and ICH-onset date with a comparison cohort of 359 185 individuals from the general population without a prior ICH. Both cohorts were followed up for 6 months or more until December 31, 2018, for outcomes using registry data. Data were analyzed from October 1, 2021, to July 19, 2022. EXPOSURES Intracerebral hemorrhage identified by a nationwide clinical database. MAIN OUTCOMES AND MEASURES The main outcomes were ICH, ischemic stroke, myocardial infarction, and a composite of MACEs. For each outcome, a case-control study nested within the cohorts was also performed, adjusting for time-varying exposures and potential confounders. Crude absolute event rates per 100 person-years, adjusted hazard ratios (aHRs) and 95% CIs and, in the nested case-control analyses, crude and adjusted odds ratios and 95% CIs were calculated. RESULTS The ICH cohort (n = 8991; 4814 men [53.5%]; mean [SD] age, 70.7 [11.5] years) had higher event rates than the comparison cohort (n = 359 185; 192 256 men [53.5%]; mean [SD] age, 70.7 [11.5] years) for MACEs (4.16 [95% CI, 3.96-4.37] per 100 person-years vs 1.35 [95% CI, 1.33-1.36] per 100 person-years; aHR, 3.13 [95% CI, 2.97-3.30]), ischemic stroke (1.52 [95% CI, 1.40-1.65] per 100 person-years vs 0.56 [95% CI, 0.55-0.57] per 100 person-years; aHR, 2.64 [95% CI, 2.43-2.88]), and ICH (1.44 [95% CI, 1.32-1.56] per 100 person-years vs 0.06 [95% CI, 0.06-0.07] per 100 person-years; aHR, 23.49 [95% CI, 21.12-26.13]) but not myocardial infarction (0.52 [95% CI, 0.45-0.60] per 100 person-years vs 0.48 [95% CI, 0.47-0.49] per 100 person-years; aHR, 1.12 [95% CI, 0.97-1.29]). Nested case-control analyses returned risk estimates of similar magnitude as the cohort analyses. CONCLUSIONS AND RELEVANCE The findings of this cohort study suggest that Danish patients with a prior ICH had statistically significantly higher rates of MACEs than the general population, indicating a need for attention to optimal secondary prevention with blood pressure lowering and antithrombotic and statin therapies after an ICH in clinical research and practice.

Abstract
Optimal antithrombotic management after intracerebral hemorrhage remains one of the central unresolved issues for patients who survive, especially for those patients with atrial fibrillation. Given the observational nature of the studies regarding anticoagulation resumption after intracerebral hemorrhage, there is uncertainty regarding resumption of oral anticoagulation therapy and its timing. There is limited high-quality evidence to guide clinical practice, leading to significant practice variation and uncertainty for patients and providers. Here, we aim to provide the key elements to guide clinicians in their individual decision: whether or not to start or resume anticoagulation in patients with a history of intracerebral hemorrhage.

Abstract
Cardiovascular events after primary intracerebral hemorrhage (ICH) have emerged as a leading cause of poor functional outcomes and mortality during the long-term recovery after an ICH. These events encompass arterial ischemic events such as ischemic stroke and myocardial infarction, arterial hemorrhagic events that include recurrent ICH, and venous thrombotic events such as venous thromboembolism. The purpose of this review is to summarize the cardiovascular complications after ICH, epidemiology and associated risk factors, and their impact on ICH outcomes. Additionally, we will highlight possible pathophysiological mechanisms to explain the short- and long-term increased risks of ischemic and hemorrhagic events after ICH. Finally, we will highlight potential secondary stroke and venous thrombotic prevention strategies often not considered after ICH, balanced against the risk of ICH recurrence.

Abstract
Spontaneous intracerebral hemorrhage (ICH) constitutes 10-15% of all strokes, and is a significant cause of mortality and morbidity. Survivors of ICH, especially those with atrial fibrillation (AF), are at risk for both recurrent hemorrhagic and ischemic cerebrovascular events. A conundrum in the field of vascular neurology, neurosurgery, and cardiology has been the decision to initiate or resume versus withhold anticoagulation in survivors of ICH with AF. To initiate anticoagulation would decrease the risk of ischemic stroke but may increase the risk of hemorrhage. To withhold anticoagulation maintains a lower risk of hemorrhage but does not decrease the risk of ischemic stroke. In this narrative review, we discuss the evidence for and against the use of antithrombotics in ICH survivors with AF, focusing on recently completed and ongoing clinical trials.

Abstract
Objective The quality of life and activities of daily living (ADL) are generally poor among dialysis patients after intracerebral hemorrhaging, and their precise clinical course remains unclear. In addition, the association between the severity of cerebral hemorrhaging and the long-term prognosis in these patients has not been fully elucidated. This study aimed to evaluate the subsequent prognosis of hemodialysis patients who survived the acute phase of intracerebral hemorrhaging. Methods We included hemodialysis patients who were admitted to Nagasaki University Hospital between 2007 and 2015 for intracerebral hemorrhaging treatment. After excluding cases of in-hospital death, survivors were classified using the 5-point modified Rankin Scale (mRS), which specifically measures the ADL in patients with cerebrovascular diseases. The patients were followed up at the medical facilities to which they were transferred in the same medical zone until 2017. Results Out of 91 patients with cerebral hemorrhaging (65±11 years old, 66% men, hemodialysis duration 108±91 months), 62 survived until discharge. Twenty-one patients died during observation, largely due to infectious diseases, such as sepsis and pneumonia (n=16, 76%). Compared to patients with mRS 0-4 (n=31), those with mRS 5 (n=31) showed a significantly poorer prognosis. The hazard ratio adjusted for age and antiplatelets was 13.7 (95% confidence interval: 3.88-63.7, p<0.001). Conclusion Hemodialysis patients with intracerebral hemorrhaging who were bedridden showed poor outcomes. The major causes of death were infections. Therefore, these patients should be carefully monitored for infections in order to improve their prognosis.

Abstract
PURPOSE OF REVIEW To critically appraise literature on recent advances and methods using "big data" to evaluate stroke outcomes and associated factors. RECENT FINDINGS Recent big data studies provided new evidence on the incidence of stroke outcomes, and important emerging predictors of these outcomes. Main highlights included the identification of COVID-19 infection and exposure to a low-dose particulate matter as emerging predictors of mortality post-stroke. Demographic (age, sex) and geographical (rural vs. urban) disparities in outcomes were also identified. There was a surge in methodological (e.g., machine learning and validation) studies aimed at maximizing the efficiency of big data for improving the prediction of stroke outcomes. However, considerable delays remain between data generation and publication. Big data are driving rapid innovations in research of stroke outcomes, generating novel evidence for bridging practice gaps. Opportunity exists to harness big data to drive real-time improvements in stroke outcomes.

Abstract
BACKGROUND AND PURPOSE The impact of arterial ischemic events after intracerebral hemorrhage (ICH) on outcomes is unclear. This study aimed to evaluate the risk of death among ICH survivors with and without an incident arterial ischemic event. METHODS We performed a retrospective cohort study using claims data from Medicare beneficiaries with a non-traumatic ICH from January 2008 to October 2015. Our exposure was an arterial ischemic event, a composite of acute ischemic stroke or myocardial infarction (MI), identified using validated ICD-9-CM diagnosis codes. The outcome was mortality. We used marginal structural models to analyze the risk of death among ICH patients with and without an arterial ischemic event, after adjusting for confounders as time-varying covariates. RESULTS Among 8,804 Medicare beneficiaries with ICH, 2,371 (26.9%) had an arterial ischemic event. During a median follow-up time of 1.9 years (interquartile range, 0.7-3.9), ICH patients with an arterial ischemic event had a mortality rate of 21.7 (95% confidence interval [CI], 20.4-23.0) per 100 person-years compared to a rate of 15.0 (95% CI, 14.4-15.6) per 100 person-years in those without. In the marginal structural model, an arterial ischemic event was associated with an increased risk of death (hazard ratio [HR], 1.8; 95% confidence interval [CI], 1.6-1.9). In secondary analyses, the mortality risk was elevated after an ischemic stroke (HR, 1.7; 95% CI, 1.5-1.8), and MI (HR, 3.0; 95% CI, 2.4-3.8). CONCLUSIONS We found that elderly patients who survived an ICH had an increased risk of death after a subsequent ischemic stroke or MI.

Abstract
Hemorrhagic stroke accounts for a significant proportion of mortality and confers a poor quality of life with high dependency among survivors. Surgical evacuation of hematoma has the advantage of rapidly controlling the increased intracranial pressure, halting the ongoing herniation syndrome, and mitigating the secondary cascades of events mediated by the inflammatory and blood degradation products. The advantage is hindered by the concurrent insult to the healthy brain tissue while passing through the normal brain tissue. Therefore, minimally invasive approaches to evacuate the hematoma are employed, but the need for an expensive surgical armamentarium and the expert multidisciplinary team is the bottleneck for their application, particularly in low-income nations. We herein performed a study upon the role of mini craniotomy open surgical method of evacuating hematoma in selected patients with supratentorial intracerebral hemorrhage. We found a significant reduction in the surgery length, minimized risk of post-surgery complications, shortened intensive care unit stay, and reduced mortality compared to the full-fledged craniotomy and endoscopy-guided surgery. There is a need for a large-scale randomized multicenter prospective study to verify the advantages of minimally invasive approaches in the management of symptomatic supratentorial intracerebral hemorrhages.
