Impact of cerebral microbleeds on cognitive functions and its risk factors in acute cerebral infarction patients

ABSTRACT Background Cerebral microbleeds (CMBs) are subclinical lesions of the brain parenchyma and an important marker for the clinical diagnosis of central nervous system vascular disease. However, the relationship between CMBs and cerebral infarction, cerebral hemorrhage, and cognitive impairment remains unclear. Methods In order to explore the cognitive function and risk factors of patients with acute cerebral infarction (ACI) complicated with cerebral microbleeds, 190 patients with ACI were collected. The patients were divided into groups with CMBs (n = 108) and groups without CMBs (n = 82) according to the presence or absence of CMBs. The general data, various examination indicators, Montreal Cognitive Assessment Scale (MoCA) scores of the two groups of patients were analyzed. Sixty healthy controls who underwent physical examination in our hospital during the same period were included as the healthy control group. Results ACI patients with CMBs had significantly higher rates of leukoaraiosis, hyperhomocysteinemia, hypercholesterolemia, and hypertension. Cognitive function was significantly lower in ACI patients with CMBs. Serum D-dimer, serum high-sensitivity C-reactive protein, serum neuron-specific enolase, and serum S100β of ACI patients with CMBs were all negatively correlated with their MoCA scores. Conclusion ACI patients with CMBs tended to have lower cognitive abilities than ACI patients without CMBs.

The uptake pattern of 18F-sodium fluoride radioligand in brain tissue after cerebral infarction

Positron emission tomography with 18F-sodium fluoride (NaF) radioligand has been actively investigated in atherosclerosis research because it is known to detect microcalcification activity within atheroma. We studied whether NaF shows any uptake in the brain tissue of patients with acute ischemic stroke. This is a post-hoc analysis of previously reported cerebral atherosclerosis research with positron emission tomography which applied the two radioligands, 18F-fluorodeoxyglucose and NaF for the detection of culprit atheroma among 20 acute cerebral infarction patients (mean age = 75.1 ± 9.0 years; 10 women). In this study, we measured the maximum and mean standardized uptake value (SUVmax and SUVmean) of NaF uptake level in the cerebral infarct region between lesions with and without diffusion weighted image (DWI) positivity, indicating acute ischemic cell death. Correlation analysis was performed between NaF uptake levels and imaging and clinical variables, including neurological severity. The NaF uptake levels were significantly higher in DWI positive lesions than in negative lesions (SUVmax: 2.0 [0.60–4.2] versus 0.20 [0.10–0.40], p = 0.021 by Mann–Whitney U test). The intensity of NaF uptake (SUVmax) was significantly correlated with the initial neurological severity (Spearman's ρ = 0.579, p= 0.007) and white blood cell count (Spearman's ρ = 0.626, p p 0.003). During ischemic stroke NaF was concentrated in brain tissue undergoing acute cell death and its uptake intensity was correlated with neurological severity, suggesting that NaF could reflect acute ischemic cell death after stroke.

Lymphocyte-to-Monocyte Ratio Is Independently Associated with Progressive Infarction in Patients with Acute Ischemic Stroke.

From April 2017 to December 2020, we retrospectively recruited 477 patients with acute ischemic stroke (within 48 hours after onset). Progressive infarction was defined as an increase of ≥1 point in motor power or ≥2 points on the total National Institutes of Health Stroke Scale (NIHSS) within 7 days after admission and extension of the original infarction were further confirmed by diffusion-weighted imaging. Demographic characteristics, clinical information, and neuroimaging characteristics were evaluated after admission. All blood draws and initial imaging were completed within 24 hours of admission. PI occurred in 147 (30.8%) patients. Univariate analysis comparing the two groups revealed that hypertension, initial NIHSS score, discharge NIHSS score, modified Rankin scale score at 90 days, monocyte level, creatinine level, fasting glucose level, LMR, monocyte-to-high-density lipoprotein ratio (MHR), and lesion location were significantly different (P < 0.05). Multivariate logistic regression analysis showed that the odds ratio of PI increased as the quartile of LMR increased, with the lowest quartile as the reference value. Subgroup analyses showed that a high LMR was an independent predictor of PI only in large artery atherosclerosis (LAA) patients. The receiver operating characteristic (ROC) curve was drawn to estimate the predictive value of LMR for PI. For all cases, the area under the curve was 0.583 (95% CI 0.526-0.641), and the best predictive cutoff value was 3.506, with a sensitivity of 53.1% and a specificity of 63.9%. In patients with LAA, the area under the curve was 0.585 (95% CI 0.505-0.665), and the best predictive cutoff value was 3.944, with a sensitivity of 48.7% and a specificity of 72.8%. LMR was an independent predictor for progressive infarction in patients with acute ischemic stroke, especially in LAA cerebral infarction patients.

Exploring the Mechanism of the Baishao Luoshi Formula against Poststroke Spasticity by Network Pharmacology and Experimental Validation.

Post-stroke spasticity (PSS) is a major cause of disability, leading to severely impaired upper-limb flexibility and ability to walk and move, significantly affecting the quality of life of cerebral infarction patients. There is currently no recognized effective therapy. Alternatively, Chinese traditional medicine has shown promise for PSS treatment. In this regard, the BSLSF has been reported to be effective; however, its underlying mechanism remains unclear. The objective of this study is to clarify the main targets and pathways of Baishao Luoshi Formula (BSLSF) during PSS treatment, laying the foundation for further research on its pharmacological effects. In this study, network pharmacology and experimental verification were conducted to explore the potential mechanism of BSLSF systematically. After obtaining active ingredients of BSLSF from the TCMSP database, SwissTarget-Prediction and PharMapper were used to uncover BSLSF targets. PSS-related targets were gathered with GeneCards and Online Mendelian Inheritance in Man. The differentially expressed genes between BSLSF and PSS were identified by a Venn plot. The drugactive ingredient-target interaction network and Protein-protein interaction (PPI) were constructed using Cytoscape and further analyzed using the MCC algorithm of CytoHubba plugin. Then, Pathway enrichment and GO biological process enrichment analyses were performed. Subsequently, a mice model of middle cerebral artery occlusion (MCAO) was established for the in vivo experiments. We found that AKT1, TNF, CASP3, VEGFA, and CREB1 were potential targets during PSS treatment. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses showed that the mechanism of PSS was closely related to synaptic plasticity. And the immunohistochemical staining showed that BSLSF protected against ischemic stroke via the CCR5/CREB signaling pathway and probably affected synaptic plasticity. our study validated that treatment with BSLSF protected against ischemic stroke via the CCR5/CREB signaling pathway and could affect synaptic plasticity. In a sense, this study provides the basis for further extensive and in-depth analysis of BSLSF, enabling the quest for new drug targets at the same time.

Brain symmetry index predicts 3-month mortality in patients with acute large hemispheric infarction.

Quantitative electroencephalography data are helpful to predict outcomes of cerebral infarction patients. The study was performed to evaluate the value of brain symmetry index by quantitative electroencephalography in predicting 3-month mortality of large hemispheric infarction. We studied a prospective, consecutive series of patients with large supratentorial cerebral infarction confirmed within 3 days from the onset in 2 intensive care units from August 2017 to February 2020. The electroencephalography was recorded once admission. The brain symmetry index (BSI) which is divided into BSIfast and BSIslow were calculated for each electrodes pair. The outcome was mortality at 3 months after the onset. A total of 38 patients were included. The subjects were divided into the mortality group (15 patients) and survival group (23 patients). Of the BSIfast and BSIslow at each electrodes pair, higher BSIfastC3-C4, higher BSIslowC3-C4, and higher BSIslowO1-O2 were noticed in the mortality group than that in the survival group at 3 months (P = .001; P = .010; P = .009). Multivariable analysis indicated that BSIfastC3-C4 was an independent predictor of 3-month mortality (odds ratio = 1.059, 95%CI 1.003, 1.119, P = .039). BSIfastC3-C4 could significant predict 3-month mortality (area under curve = 0.805, P = .005). And when we combined BSIfastC3-C4, Glasgow Coma Scale and infarct volume together to predict the 3-month mortality, the predicted value increased (area under curve = 0.840, P = .002). BSIfastC3-C4 could independently predict the 3-month mortality of large hemispheric infarction. The combination marker which includes Glasgow Coma Scale, infarct volume, and BSIfastC3-C4 has a better diagnostic value. Further clinical trials with a large sample size are still needed.

Risk factors of acute cerebral infarction in patients with primary hypertension.

To explore the risk factors of acute cerebral infarction (ACI) in patients with primary hypertension. Patients diagnosed with primary hypertension and ACI and confirmed by MRI, who were admitted to Honghuagang District people's Hospital, Zunyi City, from January 2020 to December 2020, were selected. Concurrent patients with primary hypertension were selected as the control group. The risk factor including sex, age, smoking, drinking, laboratory examination, and other complications was analyzed. Three hundred patients with hypertensive ACI and 117 cases with hypertension were included. The laboratory examination comparison between the two groups showed that patients in the ACI group had higher glycosylated hemoglobin, D-dimer and FDPs then patients of the control group (P < 0.05). There was significant association between diabetes mellitus and acute cerebral infarction in patients with primary hypertension (OR = 1.452, P = 0.004). Poor control of blood glucose in pre-morbid diabetes mellitus may be related to the occurrence of ACI. Diabetes mellitus is an independent risk factor in ACI patients with primary hypertension.

Analysis of Hospitalization Costs in Patients Suffering from Cerebral Infarction along with Varied Comorbidities.

This study aimed to study the influence of comorbidities on hospitalization costs for inpatients with cerebral infarction. The data from the medical records pertaining to 76,563 inpatients diagnosed with cerebral infarction were collected from public hospital records for the period between 1 January 2020 and 30 December 2020 in Gansu Province. EpiData 3.1 software was used for data collation, and SPSS 25.0 was used for data analysis. Numbers and percentages were calculated for categorical variables, the chi-squared test was used to compare differences between groups, and multiple independent-sample tests (Kruskal-Wallis H test, test level α = 0.05) and multiple linear regression were used to analyze the influence of different types of comorbidity on hospitalization costs. Among the 76,563 cerebral infarction inpatients, 41,400 were male (54.07%); the average age of the inpatients was 67.68 ± 10.75 years (the 60~80-year-old group accounted for 65.69%). Regarding the incidence of varied chronic disease comorbidities concomitant with cerebral infarction, hypertension was reported as the most frequent, followed by heart disease and chronic pulmonary disease. The average hospitalization cost of cerebral infarction inpatients is US $1219.66; the hospitalization cost increases according to the number of comorbidities with which a patient suffers (H = 404.506, p &lt; 0.001); Regarding the types of comorbidities, the hospitalization cost of cancer was the highest, at US $1934.02, followed by chronic pulmonary disease (US $1533.02). Regarding the cost of hospitalization for combinations of comorbidities, cerebral infarction + chronic pulmonary disease was the most costly (US $1718.90), followed by cerebral infarction + hypertension + chronic pulmonary disease (US $1530.60). In the results of multiple linear regression analysis, cerebral infarction with chronic pulmonary disease had significant effects on hospitalization costs (β = 0.181, p &lt; 0.001), drug costs (β = 0.144, p &lt; 0.001) and diagnosis costs (β = 0.171, p &lt; 0.001). Comorbidities are significantly associated with high hospitalization costs for cerebral infarction patients. Furthermore, relevant health departments should build preventative and control systems to reduce the risk of comorbidities, as well as to improve hospital clinical pathway management and to strengthen and refine the cost-control management of cerebral infarction from the perspective of comorbidities.

Serum 4-hydroxynonenal associates with the recurrence of patients with primary cerebral infarction.

4-Hydroxynonenal (4-HNE), an α, β-unsaturated hydroxyalkenal, has been found to be associated with aspirin resistance, which is a risk factor for recurrent cerebral infarction. However, its effect on recurrent cerebral infarction is less defined. We designed this study to investigate the association between 4-HNE and increased risk of recurrent cerebral infarction. We recruited 189 patients with primary cerebral infarction from 2017 to 2019. According to the recurrence of cerebral infarction during the 3-year follow-up period, they were divided into two groups, namely, the non-recurrence group (n = 93) and the recurrence group (n = 96). All patients were analyzed to explore the risk factors for the recurrence of primary cerebral infarction and the predictive value of serum 4-HNE for the recurrence of cerebral infarction. The levels of serum 4-HNE in patients of the recurrence group were significantly higher than that in patients of the non-recurrence group. There was a positive correlation between serum 4-HNE levels and the serum levels of triglyceride (r = 0.448, p = 0.008) and low-density lipoprotein cholesterol (LDL-C; r = 0.442, p = 0.002) in primary cerebral infarction patients. Cox proportional hazards modeling showed that demographic and certain clinical parameters, such as age, serum triglyceride levels, the National Institutes of Health Stroke Scale (NIHSS) scores, and serum 4-HNE levels, were independent factors for the recurrence in patients. The results of the receiver operating characteristic (ROC) curve showed that the area under the curve (AUC) value of serum 4-HNE in patients with cerebral infarction recurrence was 0.703, and when the cutoff value of serum 4-HNE was set at 42.34 ng/ml, the sensitivity and specificity values of serum 4-HNE in predicting recurrent cerebral infarction were 79.20 and 52.70%, respectively. Serum 4-HNE is an independent risk factor for the recurrence of patients with primary cerebral infarction, and it may become a new intervention way to prevent the recurrence of patients with cerebral infarction.

The relationship between severe extracranial artery stenosis or occlusion and cerebral small vessel disease in patients with large artery atherosclerotic cerebral infarction.

Extracranial artery stenosis (ECAS) is associated with the presence of individual markers of cerebral small vessel disease (CSVD). Here, we investigated the relationship between severe extracranial artery stenosis or occlusion and CSVD in patients with large artery atherosclerotic (LAA) cerebral infarction. A total of 128 patients with LAA cerebral infarction who met our specific inclusion criteria were selected, including 92 males and 36 females. These patients were divided into three groups based on whether they had severe symptomatic extracranial arterial stenosis or occlusion, severe asymptomatic extracranial artery stenosis or occlusion, or severe extracranial artery stenosis or occlusion (both symptomatic and asymptomatic). Intra-group comparisons were then performed to examine whether there were any differences in the total CSVD scores and Fazekas scores. Patients with severe extracranial arterial stenosis or occlusion and those with severe asymptomatic extracranial arterial stenosis or occlusion had a significantly higher total CSVD score (P < 0.05), but there were no significant differences between the groups in terms of Fazekas scores. Furthermore, there were no significant difference in the total CSVD scores and Fazekas scores when compared between patients with or without severe symptomatic extracranial arterial stenosis or occlusion. Severe stenosis or occlusion of the contralateral extracranial artery may increase the incidence of CSVD in patients with LAA cerebral infarction. Active and effective clinical intervention following comprehensive evaluation should be undertaken for unilateral cerebral infarction patients with severe stenosis or occlusion of the contralateral extracranial arterial.

Clinical significance of asymmetric venous vasculature on minimum-intensity projection in patients with moyamoya disease.

This study analyzed the clinical significance and characteristics of asymmetric venous blood flow in patients with Moyamoya disease (MMD) using minimum intensity projection (minIP) susceptibility-weighted imaging. The minIP views of 30 patients diagnosed with MMD were retrospectively analyzed using clinical features, brain magnetic resonance angiography, electroencephalography, and brain single-photon emission computed tomography (SPECT). Simultaneously, differences between patients with acute cerebral infarction and non-MMD causes were analyzed. Twelve (40.0%) of the 30 patients had asymmetrical venous flow, which is usually seen in patients with acute cerebral infarction (P = .146). They also had significantly higher Suzuki stages than symmetric patients (P = .014), with five (41.7%) and three (25.0%) of them in stages 4 and 5, respectively. When the Suzuki stages of both hemispheres were different, more veins were found in the stenotic hemisphere (88.9%). Brain SPECT showed more severe hypoperfusion on the side with prominent vascularity in the minIP view (100.0%). Additionally, asymmetric blood flow was observed in 66.7% of the patients with cerebral infarction caused by MMD, whereas only 11.1% of the children with cerebral infarction caused by non-MMD had asymmetry (P = .005). Patients with MMD showed asymmetric hypointensity of the cortical veins with a minIP appearance. The venous structure showed greater signal loss on SWI and was more prominent in the hemisphere where stenosis was advanced or infarction occurred in other examinations. Cerebral infarction in patients with MMD tended to occur with asymmetrically prominent venous patterns with damaged areas in minIP images, which had distinct characteristics from those of patients without MMD.

The Association of Blood Urea Nitrogen to Creatinine Ratio and the Prognosis of Critically Ill Patients with Cerebral Infarction: A Cohort Study.

Background To evaluate the association between blood urea nitrogen (BUN) to creatinine (Cr) (BUN/Cr) ratio and the in-hospital mortality of critically ill patients with cerebral infarction in intensive care unit (ICU). Methods In this cohort study, the data of 3059 participants with cerebral infarction were collected from the Medical Information Mart for Intensive Care (MIMIC)-III and the MIMIC-IV database. After propensity score matching (PSM) on age and gender, 2085 people were involved in and divided into the alive group (n = 1390) and the dead group (n = 695) based on the results of follow-up. Multivariate logistic analyses were applied to identify the confounders and the association between BUN/Cr and mortality of cerebral infarction. Results The median follow-up time was 10.5 days. Among 2778 participants, 695 were dead at the end of follow-up. Univariate analysis revealed that BUN/Cr [risk ratio (RR) = 1.01, 95% confidence interval (CI): 1.01-1.02] might be associated with the in-hospital mortality of cerebral infarction patients. After adjusting for respiratory failure, malignant cancer, anticoagulation, liver disease, white blood cell (WBC), red cell distribution width (RDW), glucose, bicarbonate, and temperature, BUN/Cr had week correlation with the increased risk of in-hospital mortality of cerebral infarction patients (RR = 1.01, 95% CI: 1.01-1.02). Conclusion This study evaluated the association between BUN/Cr and the in-hospital mortality of cerebral infarction patients in ICU and found that BUN/Cr had weak correlation with the increased risk of in-hospital mortality of patients with cerebral infarction in ICU especially in males and those with respiratory failure, malignant cancer, and without liver disease, as well as those receiving anticoagulation.

Cholecystectomy reduces the risk of myocardial and cerebral infarction in patients with gallstone-related infection

We compared the risk of myocardial infarction (MI) or cerebral infarction (CI) in patients with or without-gallstone-related infection (GSI) and change in the risk following cholecystectomy. GSI (n = 84,467) and non-GSI (n = 406,800) patients with age- and sex-matched controls (n = 4,912,670) were identified from Korean population based data. The adjusted hazard ratios (aHRs) of MI or CI were analyzed in both groups treated with or without cholecystectomy. Subgroup analysis was performed for both sexes and different ages. The risk of MI or CI was higher in the GSI group than in the non-GSI group (aHR for MI; 1.32 vs. 1.07, aHR for CI; 1.24 vs. 1.06, respectively). The risk reduction rate of MI following cholecystectomy was 11.4% in the GSI group, whereas it was 0% in the non-GSI group. The risk of CI after cholecystectomy was more reduced in the GSI group than in the non-GSI group (16.1% and 4.7%, respectively). The original risk of MI or CI in patients with gallstones and risk reduction rates following cholecystectomy were higher in females and younger patients than in males and older patients. Increased risk of MI or CI and greater risk reduction following cholecystectomy were seen in patients with GSI.

Silent cerebral infarcts in patients with atrial fibrillation: Clinical implications of an imaging-adjusted CHA2DS2-VASc score.

BackgroundThe CHA2DS2-VASc score does not include silent infarcts on neuroimaging in stroke risk estimation for patients with atrial fibrillation (AF). The inclusion of silent infarcts into CHA2DS2-VASc scoring and its impact on stroke prophylaxis recommendations in patients with AF has not been previously studied. The present study sought to quantify the prevalence of silent infarcts in patients with AF and describe potential changes in management based on magnetic resonance imaging (MRI) findings.MethodsParticipants from the Mayo Clinic Study of Aging with AF and brain MRI were included. Silent infarcts were identified. “Standard” CHA2DS2-VASc scores were calculated for each subject based on clinical history alone and “imaging-adjusted” CHA2DS2-VASc scores based on evidence of cerebral infarction on MRI. Standard and imaging-adjusted scores were compared.ResultsOne hundred and forty-seven participants (average age 77, 28% female) were identified with AF, MRI, and no clinical history of stroke. Overall, 41 (28%) patients had silent infarcts on MRI, corresponding with a 2-point increase in CHA2DS2-VASc score. Of these participants, only 39% (16/41) with silent infarct were on anticoagulation despite having standard CHA2DS2-VASc scores supportive of anticoagulation. After incorporating silent infarcts, 13% (19/147) would have an indication for periprocedural bridging compared to 0.6% (1/147) at baseline.ConclusionsIncorporation of silent infarcts into the CHA2DS2-VASc score may change the risk-benefit ratio of anticoagulation. It may also increase the number of patients who would benefit from periprocedural bridging. Future research should examine whether an anticoagulation strategy based on imaging-adjusted CHA2DS2-VASc scores could result in a greater reduction of stroke and cognitive decline.

Impact of Treatment Timing on the Risk of Cerebral Infarction in Patients with Aneurysmal Subarachnoid Hemorrhage

Cerebral infarction is a major contributor to poor outcome in patients with aneurysmal subarachnoid hemorrhage (aSAH). Timing of treatment has been discussed as a possible contributor. We aimed to analyze the impact of treatment timing on the risk of cerebral infarction and poor outcome following aSAH. Consecutive aSAH cases treated at our institution between 01/2003 and 06/2016 were included. The cohort was divided into two groups, depending on the treatment during (day 4 - 14 after ictus) or beyond the vasospasm phase. Statistical assessment included a 1:1 propensity-score matching analysis and multivariable logistic regression analysis within the whole cohort. Out of 943 aSAH patients included, 111 individuals underwent treatment in the vasospasm phase. In the propensity-score matching analysis, patients treated during the vasospasm phase were at higher risk of vasospasm requiring intra-arterial spasmolysis (IAS) (p<0.0001), cerebral infarction distal to the treated vessel (p<0.0001), and poor outcome (mRS>2) at 6 months follow-up (p=0.025). In the multivariable analysis, aneurysm treatment in the vasospasm phase was independently associated with higher risk of cerebral vasospasm necessitating IAS (p<0.0001; aOR=3.62), cerebral infarction distal to the treated aneurysm (p=0.01; aOR=2.02) and poor outcome (p=0.03; aOR=2.05). Our data confirm a considerable risk of cerebral infarction and poor outcome in case of aneurysm treatment between day 4 and 14 post-aSAH. A more intense surveillance and prophylactic treatment of cerebral vasospasm might be necessary in case of aneurysm treatment in the "vasospasm phase".

Effect of Xingnao Kaiqiao acupuncture on safety of rt-PA intravenous thrombolysis in patients with cerebral infarction: a randomized controlled trial

To assess the effect of Xingnao Kaiqiao (regaining consciousness and opening orifices) acupuncture on the efficacy and safety of intravenous thrombolysis with recombinant tissue plasminogen activator (rt-PA) in patients with cerebral infarction. A total number of 142 patients of cerebral infarction undergoing rt-PA intravenous thrombolysis were randomized into an acupuncture-medication group (71 cases) and a western medication group (71 cases, 1 case dropped off). In the western medication group, rt-PA intravenous thrombolysis was given. In the acupuncture-medication group, besides the intervention as the control group, Xingnao Kaiqiao acupuncture was provided at Shuigou (GV 26), Neiguan (PC 6), Sanyinjiao (SP 6), Jiquan (HT 1), etc. once daily. One treatment session contained 6 treatments and 1 session was required. Before and after treatment, the score of the National Institute of Health stroke scale (NIHSS), the levels of the relevant indexes of symptomatic intracerebral hemorrhage (sICH) (platelet [PLT], D-dimer and fibrinogen), the incidences of sICH and adverse effect were compared between groups. The efficacy was assessed in two groups. After treatment, NIHSS scores and the levels of D-dimer were reduced compared with those before treatment in both groups (P<0.05), and those in the acupuncture-medication group were lower than the western medication group (P<0.05). The level of fibrinogen in the acupuncture-medication group was increased in comparison with that before treatment (P<0.05), and also higher than the western medication group (P<0.05). The incidence of sICH was 0% (0/71) in the acupuncture-medication group, lower than 8.6% (6/70) in the western medication group (P<0.05). The effective rate was 97.2% (69/71) in the acupuncture-medication group, higher than 87.1% (61/70) in the western medication group (P<0.05). The incidence of adverse effect was 2.8% (2/71) in the acupuncture-medication group, lower than 12.9% (9/70) in the western medication group (P<0.05). Xingnao Kaiqiao acupuncture may improve the efficacy of rt-PA intravenous thrombolysis in the patients with cerebral infraction and decrease the incidences of sICH and adverse effect. The mechanism may be related to the regulation of fibrinogen and D-dimer levels.
