Abstract
INTRODUCTION Intracerebral haemorrhage (ICH) is a neurological emergency with high morbidity and mortality, and current treatment is limited. Emerging evidence has reported that statins can exert neuroprotective effects in cerebrovascular diseases. However, most of the published clinical studies are retrospective. Therefore, it is important to conduct a prospective randomised controlled trial to further validate the efficacy and safety of statins in patients with ICH. METHODS AND ANALYSIS The present study is performed at Xuan Wu Hospital Capital Medical University, Beijing Fengtai You'anmen Hospital and Shunping County Hospital, Hebei Province. The target number of patients is 98. Eligible patients are randomly assigned in a 1:1 ratio to the statins group or the control group. The primary outcome is the perihaemorrhagic oedema to haematoma ratio at 7 days. Secondary outcomes include mortality at 30 days, haematoma resolution rate at 7 days, National Institute of Health stroke scale (NIHSS) score at 7 days or discharge, ordinal distribution of modified Rankin scale (mRS) score at 90 days, the proportion of patients with an mRS score of 0-2 on day 90, the proportion of patients with an mRS score of 0-3 on day 90, absolute haematoma volume changes between initial and 7-day follow-up CT scan, absolute perihaematomal oedema changes between initial and 7-day follow-up CT scan. ETHICS AND DISSEMINATION The trial has been approved by the ethics committees of Xuan Wu Hospital Capital Medical University, Beijing Fengtai You'anmen Hospital and Shunping County Hospital, Hebei Province. The results will be disseminated in a peer-reviewed journal and in conference reports. TRIAL REGISTRATION NUMBER NCT04857632.

Relationship between prior statin therapy and radiological features and clinical outcomes of intracerebral hemorrhage. J Stroke Cerebrovasc Dis 2023; 32:107378. [PMID: 37837803 DOI: 10.1016/j.jstrokecerebrovasdis.2023.107378] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Accepted: 09/16/2023] [Indexed: 10/16/2023] Open
Abstract
OBJECTIVES A post-hoc analysis of the ICH Deferoxamine (i-DEF) trial was performed to examine any associations pre-ICH statin use may have with ICH volume, PHE volume, and clinical outcomes. MATERIALS AND METHODS Baseline characteristics were assessed. Various ICH and PHE parameters were measured via a quantitative, semi-automated method at baseline and follow-up CT scans 72-96 h later. A multivariable logistic regression model was created, adjusting for the variables that were significantly different on univariable analyses (p < 0.05), to assess any associations between pre-ICH statin use and measures of ICH and PHE, as well as good clinical outcome (mRS ≤2), at 90 and 180 days. RESULTS 262 of 291 i-DEF participants had complete data available for analysis. 69 (26.3 %) used statins prior to ICH onset. Pre-ICH statin users had higher prevalences of hypertension, diabetes, and prior ischemic stroke; higher concomitant use of antihypertensives and antiplatelets; and higher blood glucose level at baseline. On univariable analyses, pre-ICH statin users had smaller baseline ICH volume and PHE volume on repeat scan, as well as smaller changes in relative PHE (rPHE) volume and edema extension distance (EED) between the baseline and repeat scans. In the multivariable analysis, none of the ICH and PHE measures or good clinical outcome was significantly associated with pre-ICH statin use. CONCLUSION Pre-ICH statin use was not associated with measures of ICH or PHE, their growth, or clinical outcomes. These findings do not lend support to either overall protective or deleterious effects from statin use before or after ICH.

Abstract
Background Current studies indicate a contradictory relationship between decreased mortality risks of spontaneous intracerebral hemorrhage (sICH) and elevated low-density lipoprotein cholesterol (LDL-C) levels. Thus, this meta-analysis was designed to examine the involvement of high LDL-C levels in a lower mortality risk of sICH patients. Methods PubMed, Cochrane, and Embase databases were searched up to the date of August 3rd, 2022. Pooled odds ratio (OR) with a 95% confidence interval (CI) was estimated for the higher vs. lower serum LDL-C level groups. Subgroup and sensitivity analyses were also carried out. Egger's test was applied to detect any potential publication bias. Results Of 629 citations reviewed, 8 eligible cohort studies involving 83,013 patients were enrolled in this meta-analysis. Compared with lower serum LDL-C levels containing patients, higher serum LDL-C patients exhibited significantly decreased risks of 3-month mortality (OR: 0.51; 95%CI: 0.33-0.78; I2 = 47.8%); however, the LDL-C level change wasn't significantly associated with in-hospital mortality risks (OR: 0.92; 95%CI: 0.63-1.33; I2 = 91.4%) among sICH subjects. All studies included were classified as high-quality investigations. Conclusions This meta-analysis suggests a higher LDL-C level may decrease the mortality risk in sICH patients. LDL-C level increase is inversely associated with the 3-month mortality risks in these patients but not significantly correlated with the in-hospital mortality risks. Further well-designed prospective studies with extended follow-up periods are needed to confirm these findings and explore underlying cross-talks.

Abstract
OBJECTIVES We examined the relationship between statin use during hospitalisation and mortality in patients with intracerebral haemorrhage (ICH). DESIGN Retrospective propensity-matched cohort study. SETTING Patients with ICH (≥18 years old) admitted to Beth Israel Deaconess Medical Center (Boston, Massachusetts, USA) from 2001 to 2012 registered in the Medical Information Mart for Intensive Care III database. PARTICIPANTS 1043 patients with ICH (≥18 years) were evaluated for the relationship between statin use during hospitalisation and mortality. INTERVENTIONS Statin use. PRIMARY AND SECONDARY OUTCOME MEASURES The primary outcome was 90-day mortality. We used multivariable Cox regression analyses to calculate the adjusted HR with 95% CI and used propensity score analysis and an inverse probability weighting (IPW) model to ensure the robustness of our findings. RESULTS We included 1043 patients with ICH (362 and 681 were statins and non-statin users, respectively) between 2001 and 2012. The overall 90-day mortality was 29.8% (311/1043); it was 33.3% (227/681) and 23.2% (84/362) for non-statin and statin users, respectively. After adjusted for potential confounders, we found that statin use was associated with 29% lower of 90-day mortality (HR=0.71, 95% CI 0.52 to 0.97, p<0.05). IPW also demonstrated a significantly lower 90-day mortality in statin users. The HR was 0.69 (95% CI 0.54 to 0.88, p<0.01). The results remain stable in subgroup analyses and propensity score matching. CONCLUSION Statin use during hospitalisation may be associated with reduced risk-adjusted mortality in patients with ICH. Further randomised controlled trials are needed to clarify this association.

Abstract
Stroke is the second highest cause of death globally, with an increasing incidence in developing countries. Intracerebral hemorrhage (ICH) accounts for 10-15% of all strokes. ICH is associated with poor neurological outcomes and high mortality due to the combination of primary and secondary injury. Fortunately, experimental therapies are available that may improve functional outcomes in patients with ICH. These therapies targeting secondary brain injury have attracted substantial attention in their translational potential. Here, we summarize recent advances in therapeutic strategies and directions for ICH and discuss the barriers and issues that need to be overcome to improve ICH prognosis.

Abstract
Intracerebral hemorrhage (ICH) is a common subtype of stroke and places a great burden on the family and society with a high mortality and disability rate and a poor prognosis. Many findings from imaging and pathologic studies have suggested that cerebral ischemic lesions visualized on diffusion-weighted imaging (DWI) in patients with ICH are not rare and are generally considered to be associated with poor outcome, increased risk of recurrent (ischemic and hemorrhagic) stroke, cognitive impairment, and death. In this review, we describe the changes in cerebral blood flow (CBF) and DWI lesions after ICH and discuss the risk factors and possible mechanisms related to the occurrence of DWI lesions, such as cerebral microangiopathy, cerebral atherosclerosis, aggressive early blood pressure lowering, hyperglycemia, and inflammatory response. We also point out that a better understanding of cerebral DWI lesions will be a key step toward potential therapeutic interventions to improve long-term recovery for patients with ICH.

Abstract
Intracerebral hemorrhage (ICH) is a fatal disease with high mortality and poor prognosis that triggers multiple severe brain injuries associated with an inflammatory cascade response that cannot be treated with any effective medication. Atorvastatin (ATO) suppresses inflammation, alleviates brain trauma, and eliminates subdural hematoma. Dexamethasone (DXM) also has the capacity to inhibit inflammation. Thus, we combined ATO with low-dose DXM to treat ICH mice in vivo to examine whether the combined treatment can inhibit secondary inflammation around the cerebral hemorrhage and decrease overall mortality. Compared to the monotherapy by either ATO or DXM, the combined treatment significantly improves the survivorship of the ICH mice, accelerates their recovery of impaired neurological function, and modulates the circulating cytokines, oxidative products, and apoptosis. Moreover, the benefit of ATO-DXM combination therapy was most pronounced on day 3 after dosing compared to ATO or DXM alone. Thus, early administration of ATO combined with low-dose-DXM promotes better survival of ICH and improves neurological function by reducing neuroinflammation and brain edema in their early phase.

Abstract
Objective In order to explore whether the application of statins can improve the prognosis of patients with intracerebral hemorrhage. Methods Studies of patients with intracerebral hemorrhage taking statins published in English until December 2021 were searched based on limited search terms, the retrieved literature was screened out based on inclusion and exclusion criteria, and the quality assessment and data extraction were carried out independently by two investigators. The extracted clinical data were then meta-analyzed. Results A total of 17 literatures were included in this study, with a sample size of 16,988 cases, including 3,001 cases in the statin group and 13,487 cases in the control group. MRS score of mortality was used as the prognostic index to evaluate cerebral hemorrhage. According to the Newcastle-Ottawa Scale (NOS), the score of literature quality evaluation scale was 6-8, indicating good literature quality. Meta-analysis of clinical data extracted from the literature showed that the statin group reduced overall mortality after intracerebral hemorrhage compared with the nonstatin group (P < 0.01). In terms of improving functional prognosis, the statin group improved functional prognosis 90 days after intracerebral hemorrhage (P=0.01). There was no significant difference between the statin and nonstatin groups in reducing the number of intracerebral hematomas. Conclusions Statins can reduce the total mortality after ICH and improve the survival rate (90 d), without increasing the amount of hematoma.

Abstract
INTRODUCTION The objective of the study was to analyze the risk factors for worsening of the disease progression in patients with chronic subdural hematomas (CSDH) during wait-and-observation treatment regimen and conservative treatment with atorvastatin. METHODS A total of 196 patients with CSDH were recruited (98 in the atorvastatin group and 98 in the blank placebo group). Receiver operating characteristic (ROC) curve analysis was used to identify the optimal cutoff for the hematoma volume by testing surgical and nonsurgical outcomes. Other measures, including univariate and multivariate analyses, were performed to identify the potential significant factors indicative of the outcome of therapeutic efficacy of conservative treatment through the characteristics of the baseline indicators at enrollment. RESULTS Over a median treatment duration of 2 months, lower total cholesterol, higher hematoma volume, and more midline shift were independent risk factors for worse outcomes of atorvastatin treatment for CSDH, and only a higher hematoma volume was an independent risk factor for spontaneous absorption in the placebo group. ROC analysis of all of the data showed that the optimal threshold of hematoma volume was 68.5 ml (sensitivity 73.5%, specificity 74%) in response to the greatest chance of switching to surgery. CONCLUSIONS Critical independent predictors of atorvastatin monotherapy treatment success included higher total cholesterol, lower hematoma volume, and less midline shift in atorvastatin monotherapy, and higher hematoma volume was the only independent risk factor in close follow-up observation patients without any pharmacotherapy. Initial hematoma volume more than 68.5 ml may help clinicians to determine individual risk assessments and to make optimal treatment decisions. TRIAL REGISTRATION http://www. CLINICALTRIALS gov .

Abstract
BACKGROUND/OBJECTIVE Diffusion weighted imaging (DWI) lesions have been well described in patients with acute spontaneous intracerebral hemorrhage (sICH). However, there are limited data on the influence of these lesions on sICH functional outcomes. We conducted a prospective observational cohort study with blinded imaging and outcomes assessment to determine the influence of DWI lesions on long-term outcomes in patients with acute sICH. We hypothesized that DWI lesions are associated with worse modified Rankin Scale (mRS) at 3 months after hospital discharge. METHODS Consecutive sICH patients meeting study criteria were consented for an magnetic resonance imaging (MRI) scan of the brain and evaluated for remote DWI lesions by neuroradiologists blinded to the patients' hospital course. Blinded mRS outcomes were obtained at 3 months. Logistic regression was used to determine significant factors (p < 0.05) associated with worse functional outcomes defined as an mRS of 4-6. The generalized estimating equation (GEE) approach was used to investigate the effect of DWI lesions on dichotomized mRS (0-3 vs 4-6) longitudinally. RESULTS DWI lesions were found in 60 of 121 patients (49.6%). The presence of a DWI lesion was associated with increased odds for an mRS of 4-6 at 3 months (OR 5.987, 95% CI 1.409-25.435, p = 0.015) in logistic regression. Using the GEE model, patients with a DWI lesion were less likely to recover over time between 14 days/discharge and 3 months (p = 0.005). CONCLUSIONS DWI lesions are common in primary sICH, occurring in almost half of our cohort. Our data suggest that DWI lesions are associated with worse mRS at 3 months in good grade sICH and are predictive of impaired recovery after hospital discharge. Further research into the pathophysiologic mechanisms underlying DWI lesions may lead to novel treatment options that may improve outcomes associated with this devastating disease.

Neuroprotective Therapies for Spontaneous Intracerebral Hemorrhage. Neurocrit Care 2021; 35:862-886.

Abstract
Patients who survive the initial ictus of spontaneous intracerebral hemorrhage (ICH) remain vulnerable to subsequent injury of the perilesional parenchyma by molecular and cellular responses to the hematoma. Secondary brain injury after ICH, which contributes to long-term functional impairment and mortality, has emerged as an attractive therapeutic target. This review summarizes preclinical and clinical evidence for neuroprotective therapies targeting secondary injury pathways following ICH. A focus on therapies with pleiotropic antiinflammatory effects that target thrombin-mediated chemotaxis and inflammatory cell migration has led to studies investigating statins, anticholinergics, sphingosine-1-phosphate receptor modulators, peroxisome proliferator activated receptor gamma agonists, and magnesium. Attempts to modulate ICH-induced blood-brain barrier breakdown and perihematomal edema formation has prompted studies of nonsteroidal antiinflammatory agents, matrix metalloproteinase inhibitors, and complement inhibitors. Iron chelators, such as deferoxamine and albumin, have been used to reduce the free radical injury that ensues from erythrocyte lysis. Stem cell transplantation has been assessed for its potential to enhance subacute neurogenesis and functional recovery. Despite promising preclinical results of numerous agents, their outcomes have not yet translated into positive clinical trials in patients with ICH. Further studies are necessary to improve our understanding of the molecular events that promote damage and inflammation of the perihematomal parenchyma after ICH. Elucidating the temporal and pathophysiologic features of this secondary brain injury could enhance the clinical efficacy of neuroprotective therapies for ICH.

Abstract
Aim The effect of statins is well established in cardiac and cerebrovascular diseases. However, its impact on intracerebral hemorrhage (ICH) is unclear. We aim to identify an association of pre-ICH statin treatment and statin use during admission for ICH with functional outcome at discharge and 30-day mortality. Material and methods A retrospective cohort study was held in patients with ICH admitted to our stroke unit over a year period. Demographic characteristics, risk factors and cardiovascular diseases, Glasgow Coma Scale (GCS), National Institutes of Health Stroke Score (NIHSS), systolic blood pressure (SBP) at admission, cholesterol levels and radiologic findings were analyzed to explore the association between pre-ICH and inpatient statin use with outcomes. The primary endpoint was functional outcome defined as modified Rankin Score (mRS) at discharge and 30-day mortality. We performed a univariate analysis and the variables with statistical significance were included in a multivariate analysis to control for confounding covariates. Results The study included 78 patients, 33 (42.31%) had previous statin intake history, of which 13 (39.39%) maintained statin intake during hospitalization. Regarding functional outcome we did not report a statistically significant difference between groups. In the “pre-ICH statin use” group a decreased 30-day mortality (6.06%, p = 0.009) was observed. In this group it was also noted higher antiplatelet medication use (33.33%, p = 0.006), higher GCS at admission (13-15: 84.38%, p = 0.018) and deep ICH (81.82%, p = 0.030). However, 30-day mortality had no impact in multivariate regression (Odds ratio (OR) 4.535, 95% Confidence Interval (CI) = 0.786-26.173, p = 0.091). In the group that maintained statin treatment during hospitalization no deaths were registered (p = 0.020) and there was no association with functional status. Multivariate regression analysis was not performed due to sample size. Conclusion The only association demonstrated in this study was lower 30-day mortality with pre-ICH statin use and continued statin treatment during admission. However, this was not confirmed by multivariate regression analysis. There were no differences between groups concerning cholesterol values, results that can be explained by the pleiotropic and immunomodulatory effect of statins. However, prospective studies are needed to prove the benefit of the statins in ICH.

Association between Serum Lipid and Hematoma Expansion after Spontaneous Intracerebral Hemorrhage in Chinese Patients. J Stroke Cerebrovasc Dis 2020; 29:104793. [PMID: 32224203 DOI: 10.1016/j.jstrokecerebrovasdis.2020.104793] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2020] [Revised: 02/22/2020] [Accepted: 02/26/2020] [Indexed: 01/05/2023] Open
Abstract
OBJECTIVES Although several studies have shown that interventions to lower blood lipid concentration may reduce the risk of coronary arterial disease and ischemic stroke, the correlation between serum lipid levels and hemorrhagic stroke remains controversial. To clarify any possible association between serum lipid and hematoma expansion, we examined various serum lipid indices in patients with and without early hematoma expansion. METHODS Data of 572 intracerebral hemorrhage (ICH) patients from the cerebral small vessel disease cohort of Peking Union Medical College Hospital were retrospectively analyzed. Patients who finished the baseline brain computed tomography (CT) examination within 6 h post-ictus and the follow-up CT within 48 h after initial CT were included in the study. Hematoma expansion was delimited as an enlargement of hemorrhage volume over 33% or 12.5 mL between baseline and subsequent CT. Both uni- and multivariate logistic regression analyses were conducted to explore the association between early hematoma growth and various serum lipid indices, including triglycerides, total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), non-HDL-C, ratios of LDL-C/HDL-C and LDL-C/TC, as well as other demographic and clinical features. RESULTS Out of 157 patients included in the analysis, hematoma growth occurred in 45 (28.7%). Only higher baseline systolic blood pressure was found to be correlated with an increased risk of hematoma growth based on both univariate (odds ratio [OR] 1.014, 95% confidence interval [CI]: 1.002-1.026, P = .024) and multivariate logistic regression analyses (OR 1.022, 95%CI: 1.008-1.037, P = .003). No associations were detected between the various serum lipid indices examined and other clinical features with a likelihood of early hematoma growth between groups or within various subgroups defined by different characteristics including age, gender, baseline Glasgow Coma Scale score, systolic blood pressure, intraventricular extension, and hematoma location. CONCLUSIONS No association between various indices of serum lipid and hematoma growth was identified among patients and subgroups with spontaneous ICH in the Chinese population; these findings may help to guide lipid management after ICH. However, further multi-centered, larger scale studies are expected to verify our results.

Abstract
Statins are effective cholesterol-lowering drugs for reducing the risks of mortality and morbidity of cardiovascular diseases. Increasing evidence has shown that statin use is associated with a significant beneficial effect in patients with ischemic stroke. Both pre-stroke and post-stroke statin use has been found to be beneficial in ischemic stroke. Furthermore, good adherence is associated with a better clinical outcome, and statin withdrawal is associated with a poor functional outcome in patients with ischemic stroke. High-intensity statin therapy is advocated for the treatment of ischemic stroke. However, there are concerns regarding the adverse effects associated with statin use in ischemic stroke such as intracranial hemorrhage. In this review, we summarize the beneficial effect of statin use in ischemic stroke and discuss the potential risks associated with statin therapy.

Abstract
Background and Purpose- Previously, murine models Krit1 +/- Msh2 -/ - and Ccm2 +/ - Trp53 -/ - showed a reduction or no effect on cerebral cavernous malformation (CCM) burden and favorable effects on lesional hemorrhage by the robust Rock (Rho-associated protein kinase) inhibitor fasudil and by simvastatin (a weak pleiotropic inhibitor of Rock). Herein, we concurrently investigated treatment of the more aggressive Pdcd10/Ccm3 model with fasudil, simvastatin, and higher dose atorvastatin to determined effectiveness of Rock inhibition. Methods- The murine models, Pdcd10 +/ - Trp53 -/ - and Pdcd10 +/ - Msh2 -/ -, were contemporaneously treated from weaning to 5 months of age with fasudil (100 mg/kg per day in drinking water, n=9), simvastatin (40 mg/kg per day in chow, n=11), atorvastatin (80 mg/kg per day in chow, n=10), or with placebo (n=16). We assessed CCM volume in mouse brains by microcomputed tomography. Lesion burden was calculated as lesion volume normalized to total brain volume. We analyzed chronic hemorrhage in CCM lesions by quantitative intensity of Perls staining in brain sections. Results- The Pdcd10 +/ - Trp53 -/ - /Msh2 -/ - models showed a mean CCM lesion burden per mouse reduction from 0.0091 in placebos to 0.0042 ( P=0.027) by fasudil, and to 0.0047 ( P=0.025) by atorvastatin treatment, but was not changed significantly by simvastatin. Hemorrhage intensity per brain was commensurately decreased by Rock inhibition. Conclusions- These results support the exploration of proof of concept effect of high-dose atorvastatin on human CCM disease for potential therapeutic testing.

Abstract
Statins, a common drug class for treatment of dyslipidemia, may be neuroprotective for spontaneous intracerebral hemorrhage (ICH) by targeting secondary brain injury pathways in the surrounding brain parenchyma. Statin-mediated neuroprotection may stem from downregulation of mevalonate and its derivatives, targeting key cell signaling pathways that control proliferation, adhesion, migration, cytokine production, and reactive oxygen species generation. Preclinical studies have consistently demonstrated the neuroprotective and recovery enhancement effects of statins, including improved neurologic function, reduced cerebral edema, increased angiogenesis and neurogenesis, accelerated hematoma clearance, and decreased inflammatory cell infiltration. Retrospective clinical studies have reported reduced perihematomal edema, lower mortality rates, and improved functional outcomes in patients who were taking statins before ICH. Several clinical studies have also observed lower mortality rates and improved functional outcomes in patients who were continued or initiated on statins after ICH. Subgroup analysis of a previous randomized trial has raised concerns of a potentially elevated risk of recurrent ICH in patients with previous hemorrhagic stroke who are administered statins. However, most statin trials failed to show an association between statin use and increased hemorrhagic stroke risk. Variable statin dosing, statin use in the pre-ICH setting, and selection biases have limited rigorous investigation of the effects of statins on post-ICH outcomes. Future prospective trials are needed to investigate the association between statin use and outcomes in ICH.

Long-Term Follow-Up of Cerebral Amyloid Angiopathy-Associated Intracranial Hemorrhage Reveals a High Prevalence of Atrial Fibrillation. J Stroke Cerebrovasc Dis 2019; 28:104342. [PMID: 31521517 DOI: 10.1016/j.jstrokecerebrovasdis.2019.104342] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2019] [Revised: 06/17/2019] [Accepted: 08/06/2019] [Indexed: 12/13/2022] Open
Abstract
GOAL Cerebral amyloid angiopathy (CAA) is the second-most common cause of nontraumatic intracerebral hemorrhages (ICH), surpassed only by uncontrolled hypertension. We characterized the percentage, risk factors, and comorbidities of patients suffering from CAA-related ICH in relation to long-term outcomes. MATERIAL AND METHODS We performed retrospective analyses and clinical follow-ups of individuals suffering from ICH who were directly admitted to neurosurgery between 2002 and 2016. FINDINGS Seventy-four of 174 (42%) spontaneous nontraumatic lobar ICH cases leastwise satisfied the modified Boston criteria definition for at least "possible CAA." Females suffered a higher risk of CAA-caused ICH (42 of 74, 56.8%, P= .035). Atrial fibrillation as a major comorbidity was observed in 19 patients (25.7%). Recovery (decrease of modified Rankin scale [mRS]) was highest during hospitalization in the acute clinic. One-year mortality was as follows: 14 of 25 patients (56%) with probable CAA without supporting pathology, 6 of 18, and 8 of 31 patients with supporting pathology and possible CAA, respectively. Only 10 of 74 (13.6%) had favorable long-term outcomes (mRS ≤2). Increasing numbers of lobar hemorrhages, low initial Glasgow Coma Scale, and subarachnoid hemorrhage were significantly associated with poor survivability, whereas statins, antithrombotic agents, an intraventricular hemorrhage, and midline shift played seemingly minor roles. CONCLUSIONS Symptomatic ICH is a serious stage in CAA progression with high mortality. The high incidence of concurrent atrial fibrillation in these patients may support data on more widespread vascular pathology in CAA.

Abstract
BACKGROUND AND AIMS Intracerebral hemorrhage (ICH) has a higher mortality than ischemic stroke. Statin is beneficial for stroke, but high potency statin treatment has been associated with the risk of hemorrhagic stroke. The aim of this study was to assess the impact of initiating statin therapy after ICH on cardiovascular outcomes. METHODS Dyslipidemic patients were retrieved from the ICH population from the National Health Insurance Research Database in Taiwan. We retrospectively compared patients prescribed with and without statin treatment after ICH. Outcomes of interest were mortality, myocardial infarction, ischemic stroke, and hemorrhagic stroke during 5 years of follow-up. RESULTS Of 17,980 adult patients with ICH and dyslipidemia, 8927 were eligible for analysis over the study period, including 1613 patients receiving statin therapy and 7314 patients not taking statins. After propensity score matching, the mean age was 61.2 ± 12.2 years in the statin group and 61.6 ± 13.0 years in the non-statin group. Hypertension was dominant, followed by diabetes mellitus, and the mean estimated NIHSS score was 12.9. The patients who received statin therapy were associated with lower risks of all-cause mortality (12.7% vs. 21.3%; hazard ratio [HR], 0.54; 95% confidence interval [CI], 0.45-0.65), cardiovascular death (4.0% vs. 7.1%; HR, 0.54; 95% CI, 0.39-0.75) and ICH (5.4% vs. 8.5%; HR, 0.62; 95% CI, 0.46-0.83) compared to those who did not receive statins. CONCLUSIONS Initiating statin therapy after ICH was associated with a decreased risk of recurrent ICH and mortality for dyslipidemia patients.

Abstract
OBJECTIVE Whether statins increase the risk of intracerebral haemorrhage (ICH) in patients with a previous stroke remains uncertain. This study addresses the evidence of statin therapy on ICH and other clinical outcomes in patients with previous ischaemic stroke (IS) or ICH. METHODS A systematic literature review and meta-analysis was performed in conformity with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to assess observational and randomised studies comparing statin therapy with control (placebo or no treatment) in patients with a previous ICH or IS. The risk ratios (RR) for the primary outcome (ICH) and secondary outcomes (IS, any stroke, mortality and function) were pooled using random effects meta-analysis according to stroke subtype. RESULTS Forty-three studies with a combined total of 317 291 patient-years of follow-up were included. In patients with previous ICH, statins had no significant impact on the pooled RR for recurrent ICH (1.04, 95% CI 0.86 to 1.25; n=23 695); however, statins were associated with significant reductions in mortality (RR 0.49, 95% CI 0.36 to 0.67; n=89 976) and poor functional outcome (RR 0.71, 95% CI 0.67 to 0.75; n=9113). In patients with previous IS, statins were associated with a non-significant increase in ICH (RR 1.36, 95% CI 0.96 to 1.91; n=103 525), but significantly lower risks of recurrent IS (RR 0.74, 95% CI 0.66 to 0.83; n=53 162), any stroke (RR 0.82, 95% CI 0.67 to 0.99; n=55 260), mortality (RR 0.68, 95% CI 0.50 to 0.92; n=74 648) and poor functional outcome (RR 0.83, 95% CI 0.76 to 0.91; n=34 700). CONCLUSIONS Irrespective of stroke subtype, there were non-significant trends towards future ICH with statins. However, this risk was overshadowed by substantial and significant improvements in mortality and functional outcome among statin users. TRIAL REGISTRATION NUMBER CRD42017079863.

Abstract
BACKGROUND AND AIMS The relationship between serum uric acid (UA) and the risk of intracerebral hemorrhage (ICH) remains controversial. The aim of our systematic review and meta-analysis was to ascertain the association between serum UA concentrations and the risk of ICH. METHODS We systematically searched databases of Embase, Pubmed, Web of Science and Cochrane Library up to December 30, 2017, and additional papers were identified through a manual search. Mean difference (MD) for serum UA levels with 95% confidence intervals (CI) was calculated. Six studies, including 345 ICH patients, 574 ischemic stroke patients and 535 healthy controls, were identified for meta-analysis. RESULTS Our results revealed no statistically significant differences in the comparison of UA between ICH and healthy controls (95% CI = -9.04-15.61); UA levels in patients with ischemic stroke were significantly higher than those in healthy controls (95% CI = 3.91-56.32); further subgroup analysis of age showed higher UA levels in ICH patients over 65 years than healthy controls (age≥65: 95% CI = 1.44-35.96). Subgroup of ethnicity (Asians: CI = -9.06-21.00; Caucasians: 95% CI = -68.43-8.43), gender (Men: 95% CI = -56.08-4.73; Women: 95% CI = -27.19-35.91) and sample size (large samples: 95% CI = -20.54-41.05; small samples: 95% CI = -25.41-13.78) with respect to UA levels between ICH and healthy controls did not change these results. CONCLUSIONS This meta-analysis showed that serum UA levels did not increase the risk of ICH probably because of the dual roles of UA, i.e. pro-oxidant and antioxidant, in the progression of atherosclerosis. However, serum UA may be a potential risk factor for ICH in the elderly. There were no race-specific differences in UA levels between Asians and Caucasians as well as gender-related differences between men and women in the risk of ICH.

Abstract
OBJECTIVE To examine the association between statin exposure in a dose-dependent manner and intracerebral hemorrhage (ICH) in a large nationwide study. METHODS The computerized database of the largest health care provider in Israel was used to identify diagnosed ICH among new users of statins, who started statin treatment between 2005 and 2010. We assessed a dose-response relationship between ICH and statins, using the average atorvastatin equivalent daily dose (AAEDD). Multivariable Cox proportional hazard regression models, adjusted for baseline disease risk score, were applied to estimate the hazard ratio of ICH. RESULTS Of the 345,531 included patients, 1,304 were diagnosed with ICH during a median follow-up of 9.5 years (interquartile range 7.6-11.0). Overall, 75.3% of patients had AAEDD <10 mg/d, 19.0% had AAEDD 0-19.9 mg/d, and 5.7% had AAEDD ≥20 mg/d. The corresponding proportions were 81.0%, 15.0%, 4.0% among ICH cases, and 75.3%, 19.0%, 5.7% among non-ICH cases. Compared to those with AAEDD <10 mg/d (reference), the adjusted hazard ratio (HR) for ICH was 0.68 (95% confidence interval [CI] 0.58-0.79) in those with AAEDD 10-19.9 mg/d, and 0.62 (0.47-0.81) in those with AAEDD ≥20 mg/d. Compared to the lowest baseline total cholesterol quartile, the adjusted HR for ICH was 0.71 (95% CI 0.62-0.82), 0.55 (0.47-0.64), and 0.57 (0.49-0.67) in those in the second, third, and highest quartiles, respectively. The results were similar and robust among highly persistent statin users and after controlling for the change in cholesterol level. CONCLUSIONS This study confirms that the risk of ICH decreases with increasing cholesterol levels, but suggests that statin use might be associated with decreased risk of ICH.

Abstract
BACKGROUND AND AIMS The relationship between lipoprotein levels, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and clinical outcome after intracerebral hemorrhage (ICH) remains controversial. We sought to evaluate the association of lipoprotein cholesterol levels and statin dosage with clinical and neuroimaging outcomes in patients with ICH. METHODS Data on consecutive patients hospitalized with spontaneous acute ICH was prospectively collected over a 5-year period and retrospectively analyzed. Demographic characteristics, clinical severity documented by NIHSS-score and ICH-score, neuroimaging parameters, pre-hospital statin use and doses, and LDL-C and HDL-C levels were recorded. Outcome events characterized were hematoma volume, hematoma expansion, in-hospital functional outcome, and in-hospital mortality. RESULTS A total of 672 patients with acute ICH [(mean age 61.6 ± 14.0 years, 43.6% women, median ICH score 1 (IQR: 0-2)] were evaluated. Statin pretreatment was not associated with neuroimaging or clinical outcomes. Higher LDL-C levels were associated with several markers of poor clinical outcome and in-hospital mortality. LDL-C levels were independently and negatively associated with the cubed root of hematoma volume (linear regression coefficient -0.021, 95% CI: -0.042--0.001; p = 0.049) on multiple linear regression models. Higher admission LDL-C (OR 0.88, 95% CI 0.77-0.99; p = 0.048) was also an independent predictor for decreased hematoma expansion. Higher admission LDL-C levels were independently (p < 0.001) associated with lower likelihood of in-hospital mortality (OR per 10 mg/dL increase 0.68, 95% CI: 0.57-0.80) in multivariable logistic regression models. CONCLUSIONS Higher LDL-C levels at hospital admission were an independent predictor for lower likelihood of hematoma expansion and decreased in-hospital mortality in patients with acute spontaneous ICH. This association requires independent confirmation.

Abstract
OBJECTIVES Clinical outcome after intracerebral hemorrhage (ICH) remains poor. Definitive phase-3 trials in ICH have failed to demonstrate improved outcomes with intensive systolic blood pressure (SBP) lowering. We sought to determine whether other BP parameters-diastolic BP (DBP), pulse pressure (PP), and mean arterial pressure (MAP)-showed an association with clinical outcome in ICH. METHODS We retrospectively analyzed a prospective cohort of 672 patients with spontaneous ICH and documented demographic characteristics, stroke severity, and neuroimaging parameters. Consecutive hourly BP recordings allowed for computation of SBP, DBP, PP, and MAP. Threshold BP values that transitioned patients from survival to death were determined from ROC curves. Using in-hospital mortality as outcome, BP parameters were evaluated with multivariable logistic regression analysis. RESULTS Patients who died during hospitalization had higher mean PP compared to survivors (68.5 ± 16.4 mm Hg vs. 65.4 ± 12.4 mm Hg; P = 0.032). The following admission variables were associated with significantly higher in-hospital mortality (P < 0.001): poorer admission clinical condition, intraventricular hemorrhage, and increased admission normalized hematoma volume. ROC analysis showed that mean PP dichotomized at 72.17 mm Hg, provided a transition point that maximized sensitivity and specific for mortality. The association of this increased dichotomized PP with higher in-hospital mortality was maintained in multivariable logistic regression analysis (odds ratio, 3.0; 95% confidence interval, 1.7-5.3; P < 0.001) adjusting for potential confounders. CONCLUSION Widened PP may be an independent predictor for higher mortality in ICH. This association requires further study.

Low cholesterol level associated with severity and outcome of spontaneous intracerebral hemorrhage: Results from Taiwan Stroke Registry. PLoS One 2017; 12:e0171379.

Abstract
The relationship between cholesterol level and hemorrhagic stroke is inconclusive. We hypothesized that low cholesterol levels may have association with intracerebral hemorrhage (ICH) severity at admission and 3-month outcomes. This study used data obtained from a multi-center stroke registry program in Taiwan. We categorized acute spontaneous ICH patients, based on their baseline levels of total cholesterol (TC) measured at admission, into 3 groups with <160, 160–200 and >200 mg/dL of TC. We evaluated risk of having initial stroke severity, with National Institutes of Health Stroke Scale (NIHSS) >15 and unfavorable outcomes (modified Rankin Scale [mRS] score >2, 3-month mortality) after ICH by the TC group. A total of 2444 ICH patients (mean age 62.5±14.2 years; 64.2% men) were included in this study and 854 (34.9%) of them had baseline TC <160 mg/dL. Patients with TC <160 mg/dL presented more often severe neurological deficit (NIHSS >15), with an adjusted odds ratio [aOR] of 1.80; 95% confidence interval [CI], 1.41–2.30), and 3-month mRS >2 (aOR, 1.41; 95% CI, 1.11–1.78) using patients with TC >200 mg/dL as reference. Those with TC >160 mg/dL and body mass index (BMI) <22 kg/m2 had higher risk of 3-month mortality (aOR 3.94, 95% CI 1.76–8.80). Prior use of lipid-lowering drugs (2.8% of the ICH population) was not associated with initial severity and 3-month outcomes. A total cholesterol level lower than 160 mg/dL was common in patients with acute ICH and was associated with greater neurological severity on presentation and poor 3-month outcomes, especially with lower BMI.

Abstract
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 ε2/ε4, 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 ε4 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.

Abstract
INTRODUCTION Although statin therapy is beneficial to patients with ischemic stroke, statin use, and intracerebral hemorrhage (ICH) remain a concern. ICH survivors commonly have comorbid cardiovascular risk factors that would otherwise warrant cholesterol-lowering medication, thus emphasizing the importance of assessing the characteristics of statin therapy in this population. METHODS We performed a cohort study by using 10 years of data collected from the National Health Insurance Research Database in Taiwan. We enrolled 726 patients admitted for newly diagnosed ICH from January 1, 2001 to December 31, 2010. The patients were categorized into high- (92), moderate- (545), and low-intensity (89) statin groups, and into hydrophilic (295) and lipophilic (431) statin groups. The composite outcomes included all-cause mortality, recurrent ICH, ischemic stroke, transient ischemic attack, and acute coronary events. RESULTS The patients in the low-intensity group did not differ significantly from the patients in the high-intensity group in risk of all-cause mortality (adjusted hazard ratio [aHR] = 0.65, 95% confidence interval [CI] = 0.28-1.55) and recurrent ICH (aHR = 0.66, 95% CI = 0.30-1.44). In contrast, the patients in the hydrophilic group had a significantly lower risk of recurrent ICH than did those in the lipophilic group (aHR = 0.69, 95% CI = 0.48-0.99). We determined no significant differences in other composite endpoints between hydrophilic and lipophilic statin use. CONCLUSION Hydrophilic statin therapy is associated with a reduced risk of recurrent ICH in post-ICH patients. The intensity of statin use had no significant effect on recurrent ICH or other components of the composite outcome. Additional studies are required to clarify the biological mechanisms underlying these observations.

Abstract
While statins play an indisputable role in primary and secondary prevention of ischemic cardiovascular and cerebrovascular disease, a concern exists regarding a possible association between low lipoprotein levels and statin use on the risk of intracerebral hemorrhage (ICH). While these data may incline physicians to discontinue statins after ICH, an increasing amount of preclinical and clinical evidence suggests that statins might have a beneficial effect on outcome and recovery in this context that goes beyond lipid lowering effects. Different etiologies of ICH and the related risk of recurrence should also be taken into account when deciding about statin use/avoidance in patients with high risk of ICH. The problem is compounded by paucity of data from randomized controlled trials and well-designed prospective observational studies. This review will discuss the existing evidence on potential interactions between statins and risk of ICH as well as outcomes in order to provide practical recommendations for clinical decision-making.

Abstract
Hemorrhagic stroke is a disease with high incidence and mortality rates. In addition to the mass lesions that result from hemorrhagic stroke, substances such as the blood-derived products (BDP) (hemoglobin (Hb), heme and iron) induce a potent inflammatory response and exert direct toxic effects on neurons, astrocytes, and microglia. In the present review, we discuss the mechanisms of brain injury secondary to hemorrhagic stroke, focusing on the involvement of BDP as major players of cellular redox imbalance, inflammation, and glutamate excitotoxicity. Potential natural mechanisms of protection against free Hb and heme such as haptoglobin and hemopexin, respectively, are highlighted. We finally discuss the experimental and clinical trials targeting free iron and heme scavenging as well as inflammation, as potential new therapies to minimize the devastating effects of hemorrhagic stroke on brain structure and function.

Abstract
BACKGROUND Growing evidence demonstrates the neuroprotective effects of statins, and the risk to develop an intracerebral hemorrhage (ICH) using statins has been refuted. However, some controversy remains regarding their role in the acute phase after ICH onset. Therefore, we performed a systematic review to investigate this issue. METHODS We searched in MEDLINE, Web of Knowledge, and Scopus databases for studies examining the outcome in patients with spontaneous ICH and statin use. The analysis was performed for short-term (≤3 months) and long-term outcome (≥6 months) and a further subanalysis considered studies seeking for the effects of the discontinuation of statin after ICH onset. A random-effect model was applied, and country was used as a cofactor for meta-regression; odds ratios (ORs) with 95% confidence intervals (CIs) are offered. RESULTS A total of 17 studies were included, only 1 pseudo cohort trial assessed the new use of statin after ICH onset and 3 studies evaluated the suspension of statin after ICH onset, the rest of the studies focused on the effect of the regular use of statin before ICH onset. The number of patients with an ICH exposed and not exposed to statins were 3455 and 11,821, respectively. The absolute short-term mortality was 27.3% in statin users and 33% in nonusers that represented a significant risk reduction of mortality (OR, .73; 95% CI, .54-.97). For long-term mortality, the effect was less evident (OR, .71; 95% CI, .43-1.15). The analysis of the 3 studies assessing the discontinuation of statins suggested a reduction of mortality risk by continuing statin (OR, .14; 95% CI, .1-.20). CONCLUSIONS The current evidence suggests that continuing statin after ICH onset might be highly related to improvement of the outcome of patients with ICH. Despite this strong suggestion, randomized controlled trials should be performed to further investigate this association.

Abstract
BACKGROUND Nonrandomized observational studies have been conducted to evaluate the effects of statins on clinical outcomes in patients with intracerebral hemorrhage. Several studies on the effects of statin administration in patients with intracerebral hemorrhage have been published recently, but the findings are inconsistent. AIM To evaluate the effects of statins administered prior to hospital admission and during hospitalization on mortality and functional outcomes in patients with intracerebral hemorrhage. SUMMARY OF REVIEW We searched for relevant literature using multiple comprehensive databases and performed a systematic review and meta-analysis. Sixteen studies met our selection criteria. Preintracerebral hemorrhage statin use was not associated with mortality (odds ratio: 0·90, 95% confidence interval: 0·63-1·28). However, patients who used statins prior to intracerebral hemorrhage had a decreased risk of mortality at three-months following symptom onset (odds ratio: 0·47, 95% confidence interval: 0·32-0·68) and an increased probability of good functional outcomes (odds ratio: 1·49, 95% confidence interval: 1·01-2·19), as compared with those who did not. In-hospital use of statins was associated with a low risk of mortality (odds ratio: 0·34, 95% confidence interval: 0·26-0·44) irrespective of preadmission statin use or postadmission time-points. Additionally, we were unable to pool the data on statin withdrawal because of differences in study methodologies. CONCLUSIONS Although careful interpretation is necessary due to several study limitations, we have demonstrated that statin use in patients with intracerebral hemorrhage is likely associated with improved mortality and functional outcomes.

Abstract
Statins are used in primary and secondary prevention of cardiovascular episodes. Most of recent studies regard ischemic stroke. There are more emerging results of studies suggesting usefulness of these drugs in the other types of stroke e.g. intracerebral hemorrhage (ICH) and subarachnoid hemorrhage (SAH). Searching for new methods of treatment is important, because both ICH and SAH lead to poor prognosis and severe psychomotor disability. The unquestionable role of inflammatory factors in the pathogenesis of these disorders justifies considering statin treatment. Previous results are contradictory, thus in present study we review results of studies and try to explain the potential pathomechanism of statin use in hemorrhagic strokes.

Perihematoma cerebral blood flow is unaffected by statin use in acute intracerebral hemorrhage patients. J Cereb Blood Flow Metab 2015; 35:1175-80. [PMID: 25757757 PMCID: PMC4640272 DOI: 10.1038/jcbfm.2015.36] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/12/2014] [Revised: 01/19/2015] [Accepted: 01/30/2015] [Indexed: 11/09/2022]
Abstract
Statin therapy has been associated with improved cerebral blood flow (CBF) and decreased perihematoma edema in animal models of intracerebral hemorrhage (ICH). We aimed to assess the relationship between statin use and cerebral hemodynamics in ICH patients. A post hoc analysis of 73 ICH patients enrolled in the Intracerebral Hemorrhage Acutely Decreasing Arterial Pressure Trial (ICH ADAPT). Patients presenting <24 hours from ICH onset were randomized to a systolic blood pressure target <150 or <180 mm Hg with computed tomography perfusion imaging 2 hours after randomization. Cerebral blood flow maps were calculated. Hematoma and edema volumes were measured planimetrically. Regression models were used to assess the relationship between statin use, perihematoma edema and cerebral hemodynamics. Fourteen patients (19%) were taking statins at the time of ICH. Statin-treated patients had similar median (IQR Q25 to 75) hematoma volumes (21.1 (9.5 to 38.3) mL versus 14.5 (5.6 to 27.7) mL, P=0.25), but larger median (IQR Q25 to 75) perihematoma edema volumes (2.9 (1.7 to 9.0) mL versus 2.2 (0.8 to 3.5) mL, P=0.02) compared with nontreated patients. Perihematoma and ipsilateral hemispheric CBF were similar in both groups. A multivariate linear regression model revealed that statin use and hematoma volumes were independent predictors of acute edema volumes. Statin use does not affect CBF in ICH patients. Statin use, along with hematoma volume, are independently associated with increased perihematoma edema volume.

Abstract
BACKGROUND AND PURPOSE Despite extensive studies of supratentorial intracerebral hemorrhage (ICH), limited data are available on determinants of hematoma volume in infratentorial ICH. We therefore aimed to identify predictors of infratentorial ICH volume and to evaluate whether location specificity exists when comparing cerebellar to brainstem ICH. METHODS We undertook a retrospective analysis of 139 consecutive infratentorial ICH cases (95 cerebellar and 44 brainstem ICH) prospectively enrolled in a single-center study of ICH. ICH volume was measured on the CT scan obtained upon presentation to the Emergency Department using an established computer-assisted method. We used linear regression to identify determinants of log-transformed ICH volume and logistic regression to evaluate their role in surgical evacuation. RESULTS Median ICH volumes for all infratentorial, cerebellar, and brainstem ICH were nine [interquartile range (IQR), 3-23], ten (IQR, 3-25), and eight (IQR, 3-19) milliliters, respectively. Thirty-six patients were on warfarin treatment, 31 underwent surgical evacuation, and 65 died within 90 days. Warfarin was associated with an increase in ICH volume of 86 % [β = 0.86, standard error (SE) = 0.29, p = 0.003] and statin treatment with a decrease of 69 % (β = -69, SE = 0.26, p = 0.008). Among cerebellar ICH subjects, those on warfarin were five times more likely to undergo surgical evacuation (OR = 4.80, 95 % confidence interval 1.63-14.16, p = 0.005). CONCLUSIONS Warfarin exposure increases ICH volume in infratentorial ICH. Further studies will be necessary to confirm the inverse relation observed between statins and ICH volume.

Abstract
BACKGROUND AND PURPOSE Controversy persists over statins and risk of intracerebral hemorrhage. We determined associations of premorbid lipid-lowering therapy and outcomes among participants of the Intensive Blood Pressure Reduction in Acute Cerebral Hemorrhage Trials (INTERACT). METHODS The pooled data of INTERACT 1 and 2 (international, multicenter, prospective, open, blinded end point, randomized controlled trials of patients with intracerebral hemorrhage [<6 hours] and elevated systolic blood pressure) were analyzed with regard to associations of baseline lipid-lowering treatment and clinical outcomes of 3184 participants in a multivariate model. Associations of lipid-lowering therapy and hematoma growth (baseline to 24 hours) in computed tomographic substudies participants (n=1310) were estimated in ANCOVA. RESULTS Among 204 patients (6.5%) with baseline lipid-lowering treatment, 90-day clinical outcomes were not significantly different after adjustment for confounding variables including region and age. In the computed tomographic substudy, 24-hour hematoma growth was greater in 124 patients (9%) with, compared with those without, prior lipid-lowering therapy. However, this association was not significant between groups (9.2 versus 6.8 mL; P<0.13), after adjustment for prior antithrombotic therapy. CONCLUSIONS No independent associations were found between lipid-lowering medication and adverse outcomes in patients with intracerebral hemorrhage.

Abstract
BACKGROUND AND PURPOSE Statin therapy is beneficial for primary and secondary prevention of ischaemic stroke, but its influence in patients with intracerebral hemorrhage (ICH) is unclear. An assessment was made of the effect of early statin therapy on patients with acute ICH. METHODS Taiwan's National Health Insurance Research Database was screened for patients without prior statin therapy admitted from January to December 2008 for newly diagnosed ICH. Patients taking statins during hospitalization or within 3 months post-discharge were the early statin group (n = 749); patients who were not were the control group (n = 7583). The study end-points were recurrent ICH and all-cause mortality during follow-up. RESULTS All eligible patients were followed up until 31 December 2010. During the follow-up, 69 (9.2%) patients in the early statin group and 677 (8.9%) control group patients had recurrent ICH. Cox proportional hazards analyses showed that early statin use did not increase the risk of recurrent ICH (adjusted hazard ratio 1.044; 95% confidence interval 0.812-1.341). During the same period, 90 (12.0%) of the early statin group and 1519 (20.0%) control group patients died. All-cause mortality was lower in the early statin group (adjusted hazard ratio 0.742; 95% confidence interval 0.598-0.919) than in the control group. Matched propensity score analyses were consistent with findings in Cox proportional hazards analyses. CONCLUSIONS Early statin group patients with acute ICH did not have a higher recurrent risk of ICH and might have lower all-cause mortality during follow-up. It is concluded that statin therapy might be beneficial for patients with ICH.

Abstract
The concept of platelets as important players in the process of atherogenesis has become increasingly accepted due to accumulating experimental and clinical evidence. Despite the progress in understanding the molecular details of atherosclerosis, particularly by using animal models, the inflammatory and thrombotic roles of activated platelet s especially in the human system remain difficult to dissect, as often only the complications of atherosclerosis, i.e., stroke and myocardial infarction are definable but not the plaque burden. Platelet indices including platelet count and mean platelet volume (MPV) and soluble mediators released by activated platelets are associated with atherosclerosis. The chemokine CXCL4 has multiple atherogenic activities, e.g., altering the differentiation of T cells and macrophages by inhibiting neutrophil and monocyte apoptosis and by increasing the uptake of oxLDL and synergizing with CCL5. CCL5 is released and deposited on endothelium by activated platelets thereby triggering atherogenic monocyte recruitment, which can be attenuated by blocking the corresponding chemokine receptor CCR5. Atheroprotective and plaque stabilizing properties are attributed to CXCL12, which plays an important role in regenerative processes by attracting progenitor cells. Its release from luminal attached platelets accelerates endothelial healing after injury. Platelet surface molecules GPIIb/IIIa, GP1bα, P-selectin, JAM-A and the CD40/CD40L dyade are crucially involved in the interaction with endothelial cells, leukocytes and matrix molecules affecting atherogenesis. Beyond the effects on the arterial inflammatory infiltrate, platelets affect cholesterol metabolism by binding, modifying and endocytosing LDL particles via their scavenger receptors and contribute to the formation of lipid laden macrophages. Current medical therapies for the prevention of atherosclerotic therapies enable the elucidation of mechanisms linking platelets to inflammation and atherosclerosis.

Abstract
AIMS To examine the relationship between statin use in Chinese patients with intracerebral hemorrhage (ICH) during their hospitalization and the outcomes. METHODS Data were collected from the China National Stroke Registry. Good functional outcome was defined by a modified Rankin Scale score between 0-2. Functional outcome and rate of mortality at 3 months and 1 year were compared between ICH patients on statin and those without it during their hospitalization. Odds ratios (ORs) with 95% confidence intervals (CI) were calculated using the multivariable logistic regression model adjusted for baseline risk factors. RESULTS Among 3218 consecutive ICH patients from 2007 to 2008, 220 (6.8%) were on statin during their hospitalization. Compared with those without statin, patients on statin were younger, had more stroke risk factors but lower stroke severity. ICH patients on statin had better functional outcome at 3 months (OR 2.24, 95% CI 1.49-3.36) and at 1 year (OR 2.04, 95% CI 1.37-3.06). They also had lower rate of mortality at 3 months (OR 0.44, 95% CI 0.22-0.87) and 1 year (OR 0.49, 95% CI 0.27-0.86). CONCLUSIONS In-hospital statin use in ICH patients is associated with better functional outcome and lower mortality at 3 months and 1 year.

Abstract
BACKGROUND AND PURPOSE We aimed to investigate the association of statin treatment with outcomes in patients with acute ischemic stroke. METHODS Over a 4.5-year period (starting November 2007), 12 781 patients (mean age, 72·8 ± 12·6 years; 48·6% women) with acute ischemic stroke from 15 hospitals in Schleswig-Holstein, Germany, were enrolled in a population-based study and prospectively evaluated. The primary outcomes were the mortality during hospitalization and the disability (modified Rankin Scale score ≥2) at discharge from hospital. The secondary outcomes were the mortality and disability at three-months after discharge. RESULTS A total of 7535 patients (59%) with acute ischemic stroke were treated with statins. During hospitalization (mean, nine-days), the in-hospital mortality rate (4·7%; 95% confidence interval, 4·3-5·1%) was lower in patients treated with statins than in those without statins (2·3% vs. 7·9%, respectively; P < 0·001). At three-months after discharge, the mortality rate (6·9%; 95% confidence interval, 6·4-7·5%) was lower in patients treated with statins than in those without statins (5·0% vs. 10·6%, respectively; P < 0·001). Adjusted logistic regression analysis showed that statin treatment was associated with reduced rates of in-hospital mortality (odds ratio, 0·39; 95% confidence interval, 0·31-0·48; P < 0·001) and three-month mortality (odds ratio, 0.47; 95% confidence interval, 0·34-0·63; P < 0·001). A comparison of the patient groups revealed that patients on statins were likely to have lower disability rates at discharge (59% vs. 67%, respectively; P < 0·001) and after three-months (33% vs. 42%, respectively; P < 0·001) in patients who had survived the stroke. CONCLUSION Statin treatment may improve the outcomes in patients with acute ischemic stroke. Further studies are necessary to confirm this finding.

Abstract
BACKGROUND AND PURPOSE Accumulating evidence suggests that statins exert neuroprotective effects, but whether their use affects the outcomes of intracerebral hemorrhage (ICH) remains controversial. Therefore, we performed a systematic review and meta-analysis to investigate whether statin use before spontaneous ICH affects unfavorable functional outcome or mortality. METHODS We searched the Cochrane Library, MEDLINE, EMBASE and China National Knowledge Infrastructure databases for studies examining the effects of pre-ICH statin use on unfavorable functional outcome, mortality or neuroimaging outcomes in consecutively recruited patients with spontaneous ICH, regardless of the duration or dose of statin treatment. RESULTS A total of 12 studies were included that examined the effects of pre-ICH statin use on post-ICH outcomes in 1652 subjects in the favors pre-statin group and 5309 in the favors no pre-ICH statin group. Meta-analysis of 11 studies suggested that pre-ICH statin use did not significantly affect mortality across all three time points tested [in-hospital, 30 days, 90 days; odds ratio (OR) 0.85, 95% confidence interval (CI) 0.70-1.03]. However, meta-analysis of seven studies showed that pre-ICH statin use did significantly decrease 90-day mortality (OR 0.72, 95% CI 0.59-0.88). Meta-analysis of six studies showed that pre-ICH statin use was not associated with significant changes in unfavorable functional outcome. Moreover, pre-ICH statin use did not significantly affect admission hematoma volume (standardized mean difference 7.75, 95% CI -5.59 to 21.09). CONCLUSION Available evidence suggests that statin use before spontaneous ICH does not increase short-term mortality, unfavorable functional outcome or post-ICH hematoma volume at admission.

Long-term improvement in outcome after intracerebral hemorrhage in patients treated with statins. J Stroke Cerebrovasc Dis 2013; 22:e541-5.

Abstract
BACKGROUND Intracerebral hemorrhage (ICH) is a severe type of stroke for which there is currently no specific medical therapy. We hypothesized that statins reduce immediate inflammatory injury and improve long-term recovery from increased neurogenesis and angiogenesis. We conducted a large retrospective cohort study to assess the influence of statin therapy on patient death and disability at 12 months after ICH. METHODS This was a retrospective analysis of a prospectively collected database at a tertiary care medical center. Patients were grouped based on statin use, and poor outcome was assessed as dead or alive with dependency (modified Barthel Index≤14). RESULTS We compared outcomes in 190 patients exposed to statins to 236 patients who were not exposed to statins. Univariate analysis found that statin use was associated with decreased mortality in-hospital and at 12 months (P=.001). Multivariable analysis found that statin use was associated with a decreased odds of death or disability at 12 months after ICH (odds ratio 0.44; 95% confidence interval 0.21-0.95). CONCLUSIONS Statin use is associated with improved long-term outcome at 12 months after ICH. This finding supports previous clinical studies that have shown the short-term benefits of statin therapy. In addition, this study correlates with animal studies supporting the possible long-term recovery benefits of statins.

Abstract
BACKGROUND AND PURPOSE It is unclear whether blood lipid profiles and statin use before intracerebral hemorrhage (ICH) are associated with its outcome. METHODS The Helsinki ICH Study, a single-center observational registry of consecutive ICH patients, was used to study the associations between premorbid statin use, baseline lipid levels, and clinical outcome. RESULTS The registry includes 964 ICH patients. Statin users (n=187; 19%) were significantly older, had more frequent comorbidities and medication, lower lipid levels, and higher admission Glasgow Coma Scale compared with nonusers. Modified Rankin Scale at discharge or mortality did not differ between statin users and nonusers. Compared with survivors, significantly lower total cholesterol and low-density lipoprotein cholesterol levels were observed in patients who died in hospital (median, 4.1 mmol/L [interquartile range, 3.6-4.4] versus 4.5 [3.8-5.1]; P<0.01; 1.9 mmol/L [1.4-2.5] versus 2.4 [1.8-3.0]; P<0.001, respectively), at 3 or 12 months. After adjusting for known ICH prognostic factors based on univariate analysis that is, age, National Institutes of Health Stroke Scale, Glasgow Coma Scale, ICH volume, and intraventricular location, lower low-density lipoprotein levels were independently associated with in-hospital mortality (odds ratio, 0.54 [95% confidence interval, 0.31-0.93]; P=0.028). CONCLUSIONS Premorbid statin use did not affect the outcome of ICH, but lower low-density lipoprotein levels were associated with higher in-hospital mortality.

Abstract
BACKGROUND AND PURPOSE Although experimental data suggest that statin therapy may improve neurological outcome after acute cerebral ischemia, the results from clinical studies are conflicting. We performed a systematic review and meta-analysis investigating the relationship between statin therapy and outcome after ischemic stroke. METHODS The primary analysis investigated statin therapy at stroke onset (prestroke statin use) and good functional outcome (modified Rankin score 0 to 2) and death. Secondary analyses included the following: (1) acute poststroke statin therapy (≤ 72 hours after stroke), and (2) thrombolysis-treated patients. RESULTS The primary analysis included 113 148 subjects (27 studies). Among observational studies, statin treatment at stroke onset was associated with good functional outcome at 90 days (pooled odds ratio [OR], 1.41; 95% confidence interval [CI], 1.29-1.56; P<0.001), but not 1 year (OR, 1.12; 95% CI, 0.9-1.4; P=0.31), and with reduced fatality at 90 days (pooled OR, 0.71; 95% CI, 0.62-0.82; P<0.001) and 1 year (OR, 0.80; 95% CI, 0.67-0.95; P=0.01). In the single randomized controlled trial reporting 90-day functional outcome, statin treatment was associated with good outcome (OR, 1.5; 95% CI, 1.0-2.24; P=0.05). No reduction in fatality was observed on meta-analysis of data from 3 randomized controlled trials (P=0.9). In studies restricted to of thrombolysis-treated patients, an association between statins and increased fatality at 90 days was observed (pooled OR, 1.25; 95% CI, 1.02-1.52; P=0.03, 3 studies, 4339 patients). However, this association was no longer present after adjusting for age and stroke severity in the largest study (adjusted OR, 1.14; 95% CI, 0.90-1.44; 4012 patients). CONCLUSIONS In the largest meta-analysis to date, statin therapy at stroke onset was associated with improved outcome, a finding not observed in studies restricted to thrombolysis-treated patients. Randomized trials of statin therapy in acute ischemic stroke are needed.
