RESUMO
OBJECTIVE: Aim: of our study was the analysis of the blood hypercoagulation risk in patients with ischemic atherotrombotic stroke depending of the VDR gene polymorphisms. PATIENTS AND METHODS: Materials and Methods: Blood of 170 patients with ischemic atherothrombotic stroke (IATS) and 124 healthy individuals (control group) was used for genotyping. Four polymorphisms (FokI, BsmI, ApaI, TaqI) of gene VDR were examined with PCR-RFLP methodology. Statistical analysis was performed by using SPSS-17.0 program. RESULTS: Results: Among patients with IATS who are carriers of the f/f genotype, FokI polymorphism of VDR gene by high thrombin time and a decrease in the rate of spontaneous fibrinolysis was registered. In individuals with the B/B genotype homozygous for the polymorphic variant, BsmI had significantly lower mean values of prothrombin and thrombin time and increased the rate of spontaneous fibrinolysis. The homozygotes for the A-allele ApaI polymorphism have 2.7 times higher risk of developing blood hypercoagulation than homozygotes for the a-allele was found. CONCLUSION: Conclusions: Biochemical signs of hypercoagulation syndrome among patients with IATS who are carriers of the f/f genotype of the FokI polymorphic variant and among B/B homozygotes of the BsmI polymorphic variant and homozygotes for the A-allele of the AÑaI polymorphism of the VDR gene were registered.

Background and Objectives: Stroke is currently the second most common cause of death and disability-adjusted life years worldwide. Previous studies have determined that cardioembolic stroke is associated with higher mortality. Our aim is to compare the long-term outcome and mortality of atherothrombotic, cardioembolic stroke patients and patients taking direct oral anticoagulants (DOACs), and to demonstrate that adequate treatment with DOACs is associated with better results. Materials and Methods: In our retrospective study, we collected the data of ischemic stroke patients who were treated at P. Stradins Clinical University Hospital, Riga, Latvia, Stroke Unit, in the year 2017. In the present study, we analyzed this information to assess the patients' demographic and clinical data, vascular risk factors, functional and neurological evaluation results, and the use of anticoagulant therapy. Stroke survivors were followed-up via telephone at 30/90/180/365 days and 4 years after being discharged from the hospital. The Latvian version of the National Institutes of Health Stroke Scale (NIHSS-LV) was used to evaluate patients' neurological outcomes at discharge, and patients' functional outcomes were evaluated using the modified Rankin scale (mRS). The collected data of the patients were separated into three groups according to the stroke subtype and use of direct oral anticoagulants. Results: A total of 654 ischemic stroke patients were admitted to the hospital in the year 2017. Of all the strokes included in the study, 262 presented an atherothrombotic etiology and 392 presented a cardioembolic etiology. The median age of the patients in the study was 76 years (IQR: 67-83). The median age of patients in the atherothrombotic stroke group was 71 years (IQR = 64-79), in the cardioembolic stroke group it was 79 (IQR = 72-84), and in the DOAC group it was 75 years (IQR = 69-82), respectively. At the period of four years, of all the atherothrombotic stroke survivors 14 (10.5%) had a severe disability, and 64 (48.1%) did not survive. However, 12 (4.1%) of the cardioembolic stroke survivors were severely disabled and 37 (12.5%) had died. In the group of patients taking DOACs 6 (4.5%) had a severe disability and 17 (12.9%) did not survive. In all the patient groups, the leading cause of death was due to severe disability (22%), followed by recurrent cardioembolic events (8%). Conclusions: Previous studies until now have concluded that cardioembolic stroke is associated with higher mortality and an unfavorable functional outcome. In our study, the cardioembolic stroke group and the DOAC group had a statistically significant higher percentage of patients with congestive heart failure and older age, but their long-term mortality was lower and they achieved independence more often than the atherothrombotic stroke patients. The proper use of anticoagulants shows great improvement in long-term survival rate and functional outcome.

Background and Purpose: Collateral flow in acute ischemic stroke is known as a predictor of treatment outcome and long-term prognosis. However, factors determining the initial collateral flow remain unclear. We investigated factors related to collateral flow in patients with acute ischemic stroke caused by large vessel occlusion (AIS-LVO) and further analyzed the results according to stroke etiology. Methods: This was a retrospective study using prospective stroke registry data from a single university hospital from October 2014 to May 2021. AIS-LVO with middle cerebral artery M1 occlusion identified by pre-treatment multiphasic computed tomography angiography was included. Collateral flow score was graded on a 6-point ordinal scale according to pial arterial filling. Results: A total of 74 patients [cardioembolism (CE): 57; large artery atherosclerosis (LAA): 17] was included. The mean age of all patients was 72.2 ± 11.7 years, and 37.8 % (n = 28) were men. Multivariate regression analysis showed that initial SBP [odds ratio (OR): 0.994; 95% confidence interval (CI): 0.990-0.998; p = 0.002] and stroke etiology (OR: 0.718; 95% CI: 0.548-0.940; p = 0.019) were independent factors of the collateral flow grade. Collateral flow grade was independently associated with initial SBP in the CE group (OR: 0.993; 95% CI: 0.989-0.998; p = 0.004) but not in the LAA group (OR: 0.992; 95% CI: 0.980-1.004; p = 0.218). Initial SBP was significantly correlated with NIHSS score in the CE group but not in the LAA group (r 2= 0.091, p = 0.023; r 2 = 0.043, p = 0.426, respectively). Conclusions: Elevated initial SBP was associated with poor cerebral collateral flow and more severe symptoms in the CE group, but not in the LAA group in patients with AIS-LVO. These findings suggest differential effects of initial SBP elevation on collateral flow by stroke subtypes.
RESUMO
Atherosclerosis is responsible for 20% of ischemic strokes, and the plaques from the internal carotid artery the most frequently involved. Lipoproteins play a key role in carotid atherosclerosis since lipid accumulation contributes to plaque progression and chronic inflammation, both factors leading to plaque vulnerability. Carotid revascularization to prevent future vascular events is reasonable in some patients with high-grade carotid stenosis. However, the degree of stenosis alone is not sufficient to decide upon the best clinical management in some situations. In this context, it is essential to further characterize plaque vulnerability, according to specific characteristics (lipid-rich core, fibrous cap thinning, intraplaque hemorrhage). Although these features can be partly detected by imaging techniques, identifying carotid plaque vulnerability is still challenging. Therefore, the study of circulating biomarkers could provide adjunctive criteria to predict the risk of atherothrombotic stroke. In this regard, several molecules have been found altered, but reliable biomarkers have not been clearly established yet. The current review discusses the concept of vulnerable carotid plaque, and collects existing information about putative circulating biomarkers, being particularly focused on lipid-related and inflammatory molecules.

AIMS: To understand the different influences of statins on the incidence rate of each stroke subtype in association with low-density lipoprotein (LDL) cholesterol levels, we performed a post hoc analysis on the data from the Japan Statin Treatment Against Recurrent Stroke (J-STARS) study. METHODS: Subjects (n=1,578) were divided into three groups according to their mean postrandomized LDL cholesterol level (ï¼100, 100-120, and ≥ 120 mg/dL) until the last observation before the event or the end of follow-up. A Cox proportional hazard model for time to events was used for calculating adjusted hazard ratios, 95% confidence intervals, and the trend tests. RESULTS: The event rates for atherothrombotic stroke did not decrease in accordance with the postrandomized LDL cholesterol level subgroups of either the control or the pravastatin group (p=0.15 and 0.33 for the trend, respectively). In the control group, however, no atherothrombotic stroke event was observed in the subgroup of the low postrandomized LDL cholesterol level (less than 100 mg/dL). The event rates for atherothrombotic stroke were lower in the middle postrandomized LDL cholesterol level subgroup (100-120 mg/dL) of the pravastatin group than that of the control group. The event rates for lacunar stroke decreased in the lower postrandomized LDL cholesterol level subgroup of the control group but not of the pravastatin group (p=0.004 and 0.06 for the trend, respectively). CONCLUSIONS: Statins showed different influences on the risks of atherothromobotic and lacunar stroke according to postrandomized LDL cholesterol levels.

Background and Purpose- Due to chronic hypoperfusion, cervical atherosclerosis may promote cerebral collateral circulation. We hypothesized that patients with ischemic stroke due to cervical carotid atherosclerosis have a more extensive collateral circulation and better outcomes than patients with cardioembolism. We tested this hypothesis in a population of patients who underwent endovascular treatment for large vessel occlusion. Methods- From the MR-CLEAN Registry (Multicenter Randomized Controlled Trial of Endovascular Treatment for Acute Ischemic Stroke in the Netherlands), we selected consecutive adult endovascular treatment patients (March 2014 to June 2016) with acute ischemic stroke due to anterior circulation large vessel occlusion and compared patients with cervical carotid artery stenosis >50% to those with cardioembolic etiology. The primary outcome was collateral score, graded on a 4-point scale. Secondary outcomes included the modified Rankin Scale (mRS) score and mortality at 90 days. We performed multivariable regression analyses and adjusted for potential confounders. Results- Of 1627 patients in the Registry, 190 patients with cervical carotid atherosclerosis and 476 with cardioembolism were included. Patients with cervical carotid atherosclerosis were younger (median 69 versus 76 years, P<0.001), more often male (67% versus 47%, P<0.001), more often had an internal carotid artery terminus occlusion (33% versus 18%, P<0.001), and a lower prestroke mRS (mRS score, 0-2; 96% versus 85%, P<0.001), than patients with cardioembolism. Stroke due to cervical carotid atherosclerosis was associated with higher collateral score (adjusted common odds ratio, 1.67 [95% CI, 1.17-2.39]) and lower median mRS at 90 days (adjusted common odds ratio, 1.45 [95% CI, 1.03-2.05]) compared with cardioembolic stroke. There was no statistically significant difference in proportion of mRS 0-2 (aOR, 1.36 [95% CI, 0.90-2.07]) or mortality at 90 days (aOR, 0.80 [95% CI, 0.48-1.34]). Conclusions- Patients with stroke due to cervical carotid atherosclerosis had a more extensive cerebral collateral circulation and a slightly better median mRS at 90 days than patients with cardioembolic stroke.

Background and objectives: NOTCH3 gene variations play a significant role in cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). However, the role of NOTCH3 gene polymorphisms in the risk of ischemic stroke, and its subtypes such as atherothrombotic or lacunar strokes, remains unclear. Aims: Hence, we carried out a meta-analysis to examine whether the NOTCH3 rs1043994, rs1044009 and rs3815188 polymorphisms are associated with ischemic stroke and its major subtypes. Materials and Methods: All relevant studies were systematically screened and meta-analyzed using Review Manager (Revman) version 5.3. The strength of the association between NOTCH3 polymorphisms and ischemic stroke risk and its subtypes were measured as odds ratios and 95% confidence intervals, under different genetic models. Results: A total of ten studies were identified, five of which considered NOTCH3 rs1043994 (2077 cases/2147 controls), five of which considered NOTCH3 rs1044009 (2315 cases/3053 controls), and nine of which considered NOTCH3 rs3815188 (2819 cases/2769 controls). These studies were meta-analyzed for their association with ischemic stroke risk. Four studies (874 cases/2002 controls) of the NOTCH3 rs3815188 polymorphism and three studies of the NOTCH3 rs1043994 (643 cases/1552 controls) polymorphism were meta-analyzed for lacunar stroke risk. Three studies (1013 cases/1972 controls) of the NOTCH3 rs3815188 polymorphism were meta-analyzed for atherothrombotic stroke risk. The meta-analysis results showed a lack of association between all of the studied polymorphisms and the risk of ischemic stroke and its major subtypes (i.e., atherothrombotic and lacunar). Conclusions: NOTCH3 polymorphisms are not significantly associated with the risk of ischemic stroke and its subtypes (p < 0.05).

Semaphorin 7A (Sema7A), a neural guidance cue, was recently identified to regulate atherosclerosis in mice. However, the clinical relevance of Sema7A with atherosclerotic diseases remains unknown. The aim of this study was to investigate the association between serum Sema7A and the risk of acute atherothrombotic stroke (AAS). We measured serum concentrations of Sema7A in 105 newly onset AAS cases and 105 age- and sex-matched controls, showing that median Sema7A level in AAS cases was over three times of that in controls (5.86 vs 1.66 ng/mL). Adjusted for hypertension, body mass index, fasting blood glucose, total cholesterol, triglyceride, high-density lipoprotein (HDL)-cholesterol, low-density lipoprotein (LDL)-cholesterol, current smoking and alcohol consumption, multivariate logistic regression showed that higher Sema7A was independently associated with the odds of AAS (OR = 6.40, 95% CI: 2.88-14.25). Each 1-standard deviation increase in Sema7A was associated with a threefold higher odds of AAS (OR = 3.42, 95% CI: 1.84-6.35). Importantly, adding Sema7A to a multivariate logistic model containing conventional cardiovascular risk factors improved the area under receiver operating characteristic curves from 0.831 to 0.891 for the association with AAS. In conclusion, elevated serum Sema7A is independently associated with the risk of AAS, suggesting that it may play a potential role in AAS.

BACKGROUND: Ischemic stroke (IS) is considered to be a heterogeneous, multifactorial disease with a strong genetic background. This study aims to determine whether variants in the antisense noncoding RNA in the INK4 locus (ANRIL) gene are associated with IS in Han Chinese, as well as whether there is evidence of a gene-environment interactions. MATERIALS AND METHODS: A case-controlled association study was conducted in which only patients with atherothrombotic stroke (ATS) were enrolled. Multifactor dimensionality reduction model was employed to screen the best interaction combinations among gene and environmental risk factors; RESULTS: A total of 405 subjects (200 cases and 205 controls) and 16 single nucleotide polymorphisms (SNPs) in ANRIL gene were included in this study. The 4 SNPs (rs1537378, rs2184061, rs7044859, and rs7865618) were found to be significantly related to ATS in Chinese Han nationality. In overall people or subjects aged 45 years or older, the GG genotype and G allele of rs1537378, the AA genotype and A allele of rs2184061 and rs7865618, and the AA genotype of rs7044859 increased the risk of ATS. In males, the GG genotype and G allele of rs1537378, the AA genotype and A allele of rs7865618, and the A allele of rs2184061 conferred a susceptibility to ATS. Additionally, the AAAGAGCAAAAAATAG haplotype exhibited an elevated risk of ATS, and a significant interaction was found in ATS susceptibility between ANRIL gene and dyslipidemia; CONCLUSIONS: The ANRIL gene was related to ATS susceptibility in a Han Chinese. Future studies should be performed with larger samples and among different ethnic populations.

BACKGROUND/PURPOSE: The copy number variants (CNVs) contain more genetic information compared with SNPs. The aim of this study was to elucidate whether the CNVs in Chromosome 9p21 region are associated with increased risk of Atherothrombotic stroke (ATS) in a Han Chinese population. METHODS: A case-controlled association study was conducted in which only patients with ATS were enrolled. The CNVs were detected by the method of multiplex competitive amplification. The differences in distribution of CNVs between cases and controls were analyzed using univariate and multivariate logistic regression analysis. Subgroup analyses were also carried out to determine whether the effect of the CNVs was specific to age and gender among the subjects. RESULTS: A total of 274 ATS patients and 282 health controls were included in the present study. 4 genes (ANRIL, CDKN2A, CDKN2B, and MTAP) including eight gene fragments in all were analyzed for CNV. The results showed that the copied number of most CNV in the 4 genes is two. There was no significant difference of CNV frequency between groups. CONCLUSIONS: The obtained data suggested a negative association between CNV of the four genes and ATS. It is necessary to perform sequencing analyses across the entire 9p21 region for detecting rare or uncommon CNV.

BACKGROUND AND PURPOSE: The ankle-brachial index (ABI) has been defined as an important factor associated with vascular events. Our objective was to analyze the prognostic value of the ABI as a predictive factor of new vascular events and functional status at 1 year in patients with non-cardioembolic ischaemic stroke. METHODS: A prospective, longitudinal, observational and multicenter study was performed, including consecutive patients ≥ 50 years old who had suffered from a non-cardioembolic ischaemic stroke. Pathological ABI (PI) was defined when the value was ≤ 0.9. The logistic regression model, survival analysis and the Cox proportional hazard regression model were used to identify factors independently associated with functional outcome and occurrence of new vascular events, including recurrent stroke. RESULTS: In all, 977 patients were evaluated. The mean age was 69.1 ± 9.5 years. 40.5% patients had PI. Stroke recurrence and new vascular events global rates were 9% and 20% respectively at 1 year. PI was independently associated with new vascular events [hazard ratio 1.764 (1.274-2.444), P = 0.001]. A cut-off point of ABI ≤ 0.8 (14% vs. 7%, P = 0.002) independently predicted stroke recurrence in an adjusted regression model [hazard ratio 1.807 (1.102-2.963), P = 0.019]. PI was also associated with functional dependence [odds ratio 1.490 (1.011-2.196), P = 0.044]. CONCLUSIONS: In non-cardioembolic ischaemic stroke patients, PI was an independent predictive factor of new vascular events and functional outcome after 1 year of follow-up.

BACKGROUND AND PURPOSE: Atherothrombotic cerebral infarction [atherothrombotic stroke (ATS)] shares common risk factors and pathophysiological mechanisms with coronary artery disease (CAD), and both diseases appear to have common susceptibility loci. The muscle RAS oncogene homolog gene (MRAS) has been identified as a susceptibility locus for CAD and is implicated in atherosclerosis. The aim of this study was to elucidate whether the single-nucleotide polymorphisms (SNPs) and haplotypes of MRAS are associated with increased risk of ATS in a population of Han Chinese. METHODS: A case-controlled association study was conducted in which only patients with ATS (identified as a major subtype in the Korean modification of the Trial of Org 10172 in Acute Stroke Treatment classification) were enrolled. Subgroup analyses were carried out to determine whether the effect of the MRAS polymorphism was specific to age and gender among the subjects. RESULTS: In total, 194 ATS and 186 control subjects were included in the present study. Two tagging SNPs were identified in MRAS (rs40593 and rs3755751). A multivariate regression analysis revealed a positive association between rs40593 and ATS under dominant and additive models after adjustment for covariates. Subgroup analyses revealed that there were no gender differences with respect to allele or genotype frequencies between the groups. The AG genotype for rs40593 (p=0.028), the CT genotype for rs3755751 (p=0.036), and G-allele carriers (AG plus GG) for rs40593 (p=0.015) exhibited a significant protective effect among those aged ≥45 years. For the haplotype analysis, ATS subjects aged ≥45 years had a higher frequency of the ACAC haplotype (76.0%) than the controls (68.1%; p<0.05); that haplotype was associated with an increased risk of ATS. CONCLUSIONS: The obtained data suggest a positive association between MRAS and ATS among the Han Chinese. Further studies should be performed with larger sample and among different ethnic populations, and gene-gene or gene-environment interactions should be considered.
RESUMO
BACKGROUND: The effects of smoking on clinical outcomes following acute stroke remain controversial. METHODS: We evaluated the influence of smoking on 90-day outcomes after acute atherothrombotic stroke in 292 Japanese men extracted from the database of the Edaravone and Argatroban Stroke Therapy for Acute Ischemic Stroke randomized parallel-group trial that tested the safety and efficacy of edaravone and argatroban therapy in 814 patients in 2004-2008. Smokers were matched with non-smokers of the same age for identical age distribution in the smoker and non-smoker groups. Poor 90-day outcomes (defined as death, Barthel index<60, or modified Rankin score>3) were evaluated using a logistic regression model. Significant variables (P<0.05) in univariate analysis were further evaluated by multivariate logistic regression analysis using a forward-selection method. RESULTS: Body temperature, age, National Institute of Health Stroke Scale score at admission, systolic blood pressure, and smoking status were selected in the final model. Smokers had significantly increased odds of poor 90-day functional outcomes independent of other statistically significant predictor variables (adjusted odds ratio, 2.28; 95% confidence interval, 1.15-4.55; P=0.019). CONCLUSIONS: In Japanese men, smoking leads to poor functional outcomes at 3 months after acute atherothrombotic stroke.

BACKGROUND: Various factors that have been implicated in recovery after the acute phase of stroke have not been well evaluated. METHODS: To identify prognostic factors affecting outcomes at 90 days after stroke from the viewpoint of recovery patterns, we enrolled 660 patients from the Edaravone and Argatroban Stroke Therapy for Acute Ischemic Stroke study database. Fourteen groups of patients were identified based on an analysis of their recovery patterns according to changes in their National Institutes of Health Stroke Scale scores during the first 21 days. These groups were then divided into 2 groups: favorable recovery trend (patterns 1-3; n = 486) and poor recovery trend (patterns 4-14; n = 174). Patterns with >80% of the patients experiencing a favorable outcome (National Institutes of Health Stroke Scale score of ≤ 4 at 90 days) were defined as the favorable recovery trend group, whereas patterns that included ≤ 80% favorable outcomes were defined as the poor recovery trend group. RESULTS: Using the poor recovery trend group, logistic regression analysis found that after controlling for covariates, lower scores at admission, fewer ischemic lesions, and nonsmoking were significant prognostic factors for a favorable outcome at 90 days. CONCLUSIONS: Based on a detailed analysis of the relationship between recovery patterns after stroke and clinical outcomes in the chronic stage of stroke, smoking cessation may improve the prognosis of patients after stroke.

Introducción: la causa más frecuente de enfermedad cerebrovascular isquémica en Cuba es el infarto cerebral de etiología aterotrombótica, que a su vez es más frecuente en el territorio anterior del encéfalo. Objetivo: caracterizar el infarto cerebral aterotrombótico reciente del territorio carotídeo, según la tomografía computarizada. Métodos: estudio descriptivo y transversal en 42 pacientes con diagnóstico clínico de infarto cerebral aterotrombótico de territorio carotídeo, a los que se les realizó tomografía de cráneo. Resultados: la presencia de infarto cerebral de origen aterotrombótico del territorio carotídeo se incrementó con la edad del paciente, alcanzó su pico máximo en los hipertensos mayores de 70 años, con mayor frecuencia en el sexo masculino. El territorio vascular más afectado fue el de la arteria cerebral media en 38 (90,5 %) enfermos, en 23 (54,7 %) pacientes hubo infartos medianos y se observó con mayor frecuencia, 24 (57,2 %) sujetos, la ausencia de infarto antiguo en el territorio anterior del cerebro. Conclusiones: el infarto cerebral aterotrombótico reciente, del territorio carotídeo, se caracteriza por la presencia de infartos medianos que afectan con mayoría casi exclusiva el territorio de la arteria cerebral media con ausencia de la enfermedad cerebrovascular antigua asociada.
Introduction: the most common cause of ischemic stroke in Cuba is atherothrombotic stroke, which, in turn, is more common in the former region of the brain. Objective: to characterize the recent atherothrombotic stroke in the carotid region, according to CT scan. Methods: a descriptive study in 42 patients with clinical diagnosis of atherothrombotic stroke in the carotid region, who underwent cranial CT. Results: the presence of atherothrombotic stroke in the carotid region increased with age. It peaked in hypertensive patients older than 70, and it is much frequently in males. The middle cerebral artery was the most affected in the vascular region in 38 (90.5 %) patients, 23 (54.7 %) patients had middle heart attacks, the absence of previous infarction in the brain anterior region was much frequently observed in 24 (57.2 %) subjects. Conclusions: the recent atherothrombotic stroke in the carotid region is characterized by the presence of middle heart attacks affecting almost exclusively the majority the middle cerebral artery region with absence of previous cerebrovascular disease associated.
