Abstract Background. Stroke is the third leading causes of death and can cause severe disability. Ischemic stroke has a higher prevalence compared to hemorrhage stroke. Hypoxia-inducible factor-1α (HIF-1α) is a transcription factor which maintains cellular homeostasis in response to hypoxia. It can trigger apoptosis while stimulating angiogenesis process and decrease neurological deficit after an ischemic stroke. However, this protein complex has not been widely investigated. Objective. Here, we examined the potential of HIF-1α as a marker for neuroplasticity process after ischemic stroke. Methods. Serum HIF-1α were measured in acute ischemic stroke patients. National Institute of Health Stroke Scale (NIHSS) were assessed on the admission and discharge day (between days 7 and 14). To classify the ischemic stroke, we used (Trial of Org 10172 in Acute Stroke Treatment) TOAST criteria. Statistical significances were calculated with Spearman rank test. Results. A total of 58 patients, 31 with large artery atherosclerosis LVD and 27 with small vessel disease (SVD) were included in this study. HIF-1α level in LVD group was (mean ± SD) 0.5225 ± 0.2459 mg/L and in SVD group was 0.3815 ± 0.121 mg/L. HIF-1α was higher (p = 0.004) in LVD group than in SVD group. The initial NIHSS score in LVD group was (mean ± SD) 15.46 ± 2.61 and discharge NIHSS score was 13.31 ± 3.449. Initial NIHSS score in SVD group was 6.07 ± 1.82 and the discharge NIHSS was 5.703 ± 1.7055. In LVD group, HIF-1α was correlated significantly with initial NIHSS (p = 0.0000) and discharge NIHSS (p = 0.0000, r = 0.93). This was also the case for SVD. We found a significant correlation between the level of HIF-1α with initial NIHSS (p = 0.0000) and discharge NIHSS (p = 0.0383) in SVD group (r = 0.94). Conclusion. HIF-1α has a strong correlation with NIHSS and it may be used as the predictor of acute ischemic stroke outcome.

Introduction: Atrial fibrillation (AF) and large artery diseases (LAD) share several risk factors and often coexist in the same patient. Optimal treatments for acute ischemic stroke (AIS) patients with concomitant AF and LAD have not been extensively studied so far. Objective: This study aimed to compare the effectiveness of the addition of antiplatelet (AP) to oral anticoagulant (OAC) with that of OAC alone in AIS with AF according to the LAD. Methods: Using a multicenter stroke registry, acute (within 48h of onset) and mild-to-moderate (NIHSS score ≤15) stroke patients with AF were identified. Propensity scores using IPTW were used to adjust baseline imbalances between the OAC+AP group and the OAC alone group in all patients and in each subgroup by LAD. The primary outcome was major vascular events, defined as the composite of recurrent stroke, MI, and all-cause mortality at up to 3 months after index stroke. Results: Among the 5469 patients (age, 72±10yrs; male, 54.9%; initial NIHSS score, 4 [2-9]), 79.0% (n=4323) received OAC alone, and 21.0% (n=1146) received OAC+AP. By weighted Cox proportional hazards analysis, a tendency of increasing the risk of 3-months primary composite events in the OAC+AP group vs the OAC alone (HR 1.36 [0.99-1.87], p=0.06), with significant interaction with treatments and LAD (Pint=0.048). Briefly, among patients with moderate-to-severe large artery stenosis, tendency of decrease in 3-months primary composite events of the OAC+AP group, compared with OAC alone group, was observed (HR 0.54 [0.17-1.70]), whereas among patients with complete occlusion, the OAC+AP group markedly increased the risk of 3-months composite events (HR 2.00 [1.27-3.15]), compared with the OAC alone group. No interaction between direct oral anticoagulant and warfarin on outcome was observed (Pint=0.35). Conclusion: In conclusion, treatment with addition of AP to OAC had a tendency to increase the risk of 3-months vascular events, compared with OAC alone in AIS with AF. However, the effects of antithrombotic treatment could be modified according to the LAD, with substantial benefits of OAC alone in subgroup of large artery occlusion. Our results address the need for the further study to tailor the optimal treatment in AIS with concomitant AF and LAD.

Arterial stiffness is an independent predictor of cardiovascular disease and stroke and can be evaluated by measuring pulse wave velocity(PWV) between 2 sites in the arterial tree, with a higher PWV indicating stiffer arteries. Recent studies have demonstrated that arterial stiffness is associated with intracranial large artery disease and the severity of cerebral small vessel disease. The aim of this study is to clarify whether pulse wave velocity value predict initial severity of acute ischemic stroke. We enrolled consecutive patients with acute ischemic stroke. Demographic factors, laboratory data, brain imaging, neurological exam and arterial stiffness measured by brachial ankle PWV (baPWV) were evaluated on admission in all subjects. The subtype of acute ischemic stroke was classified according to the TOAST classification. All patients were categorized into two groups based on the initial severity of stroke, indicated by modified Rankin Scale(mRS). Severe group was defined as a mRS ≥ 3 at admission. Unpaired student’s t-test or Mann-whitney U-test were used to compare maximal and meanbaPWV values between two groups. We enrolled 78 patients. According to the TOAST classification, the etiology of stroke was large artery disease (LAD) in 34 patients, small vessel disease (SVD) in 23 patients, and other subtypes in 12 patients. There were 28 patients with good outcome and 41 patients with poor outcome. The maximal and mean baPWV values were significantly increased in inpatients with high mRS score (2120.17± 527.75, 1999.21 ± 437.46) compared with those with low mRS score (1751.96 ± 363.49, 1723.14 ± 353.02)(p=0.001, p=0.007). In patients with SVD subtype, there was significant difference in maximal and mean baPWVvalues between two groups (p=0.030, p=0.047), whereas there was no significant difference in baPWV in patients with LAD subtype (p=0.141, p=0.172). The main finding of our study is that arterial stiffness indicated by baPWV is associated with the initial severity of acute ischemic stroke. Because initial stroke severity is strongly associated with functional outcome of stroke, this findings suggest that measurement of baPWV may predict long-term outcome in patients with stroke especially in those with TOAST classification confirmed as SVD.

Background and Purpose— In Japan, nearly half of ischemic stroke patients receive edaravone for acute treatment. The purpose of this study was to assess the effect of edaravone on neurological symptoms in patients with ischemic stroke stratified by stroke subtype. Methods— Study subjects were 61 048 patients aged 18 years or older who were hospitalized ≤14 days after onset of an acute ischemic stroke and were registered in the Japan Stroke Data Bank, a hospital-based multicenter stroke registration database, between June 2001 and July 2013. Patients were stratified according to ischemic stroke subtype (large-artery atherosclerosis, cardioembolism, small-vessel occlusion, and cryptogenic/undetermined) and then divided into 2 groups (edaravone-treated and no edaravone). Neurological symptoms were evaluated using the National Institutes of Health Stroke Scale (NIHSS). The primary outcome was changed in neurological symptoms during the hospital stay (ΔNIHSS=NIHSS score at discharge−NIHSS score at admission). Data were analyzed using multivariate linear regression with inverse probability of treatment weighting after adjusting for the following confounding factors: age, gender, and systolic and diastolic blood pressure at the start of treatment, NIHSS score at admission, time from stroke onset to hospital admission, infarct size, comorbidities, concomitant medication, clinical department, history of smoking, alcohol consumption, and history of stroke. Results— After adjusting for potential confounders, the improvement in NIHSS score from admission to discharge was greater in the edaravone-treated group than in the no edaravone group for all ischemic stroke subtypes (mean [95% CI] difference in ΔNIHSS: −0.46 [−0.75 to −0.16] for large-artery atherosclerosis, −0.64 [−1.09 to −0.2] for cardioembolism, and −0.25 [−0.4 to −0.09] for small-vessel occlusion). Conclusions— For any ischemic stroke subtype, edaravone use (compared with no use) was associated with a greater improvement in neurological symptoms, although the difference was small (<1 point NIHSS) and of limited clinical significance.

Background: It is unknown if intraprocedural blood pressure (BP) influences clinical outcomes and what BP parameter best predicts outcomes in acute ischemic stroke (AIS) patients who undergo intra-arterial therapy (IAT) for emergent large vessel occlusion. Methods: We retrospectively reviewed 147 patients who underwent IAT for anterior circulation AIS from January 2008 to December 2012 at our institution. Baseline demographics, stroke treatment variables, and detailed intraprocedural hemodynamic variables were collected. Results: The entire cohort consisted of 81 (55%) females with a mean age of 66.9 ± 15.6 years and a median National Institutes of Health Stroke Scale (NIHSS) score of 16 (IQR 11-21). Thirty-six (24.5%) patients died during hospitalization, 25 (17%) achieved a 30-day modified Rankin Scale score of 0-2, and 24 (16.3%) suffered symptomatic parenchymal hematoma type 1/2 hemorrhage. Patients who achieved a good outcome had a significantly lower admission NIHSS score, a higher baseline CT ASPECTS score, and a lower rate of ICA terminus occlusions. Successful recanalization was more frequent in the good-outcome group, while symptomatic hemorrhages occurred only in poor-outcome patients. The first systolic BP (SBP; 146.5 ± 0.2 vs. 157.7 ± 25.6 mm Hg, p = 0.042), first mean arterial pressure (MAP; 98.1 ± 20.8 vs. 109.7 ± 20.3 mm Hg, p = 0.024), maximum SBP (164.6 ± 27.6 vs. 180.9 ± 18.3 mm Hg, p = 0.0003), and maximum MAP (125.5 ± 18.6 vs. 138.5 ± 24.6 mm Hg, p = 0.0309) were all significantly lower in patients who achieved good outcomes. A lower maximum intraprocedural SBP was an independent predictor of good outcome (adjusted OR 0.929, 95% CI 0.886-0.963, p = 0.0005). Initial NIHSS score was the only other independent predictor of a good outcome. Conclusion: Lower intraprocedural SBP was associated with good outcome in patients undergoing IAT for AIS, and maximum SBP was an independent predictor of good outcome. SBP may be the optimal hemodynamic variable to monitor intraprocedurally during IAT and may predict outcome.

BackgroundNew recommendations for mechanical thrombectomy in acute ischemic stroke suggest that thrombectomy should be considered for eligible patients with a large artery occlusion in the anterior circulation within 6 hours of stroke onset. The resources are unevenly spread and, in order to be able to meet a potentially increased demand, we have estimated the future need for thrombectomy.MethodsThe new treatment recommendations are similar to those that have been in use at the Karolinska University Hospital since 2007. Using our local thrombectomy data (2009–2011), we calculated the proportion of thrombectomies performed at our hospital by level of stroke severity according to the National Institutes of Health Stroke Scale score (0–5, 6–11, 12–19, and 20–35). We then estimated the total number of potential thrombectomies expected in Sweden by extrapolating our treatment proportions to the rest of Sweden through the use of data from the Swedish National Stroke Registry.ResultsThe number of potential thrombectomies would have been more than five times higher (1268 estimated compared with 232 actually reported in the National Stroke Registry) if the new recommendations for thrombectomy in acute ischemic stroke had been implemented in 2013 (the year from which we had the most recent available data from the Swedish Stroke Registry).ConclusionsWhen the new recommendations are implemented broadly, there may be a substantial increase in demand for thrombectomies. Our study highlights the need for policymakers and healthcare professionals to prepare for the increasing demands for advanced endovascular stroke treatment.

Ischemic stroke (IS), the leading neurology cause of death and disability worldwide, is influenced by gene polymorphisms. To explore the association between IS and Apolipoprotein E (APOE) gene polymorphisms, a case–control study containing 513 IS patients and 514 controls without IS was conducted in a Northwest China Han population. MassARRAY iPLEX system was applied to determine the APOE polymorphisms according to the alleles of two single nucleotide polymorphisms (SNPs) of APOE, rs429358, and rs7412. The results showed that rs429358 and rs7412 were in Hardy–Weinberg equilibrium (HWE) in both cases and controls groups. APOE ε4 allele, ε4/ε4 genotype, and ε4-containing genotypes were associated with IS. According to the results of Trial of ORG 10172 in Acute Stroke Treatment (TOAST) classification system, APOE ε2 allele, ε4 allele, and ε4/ε4 genotype were associated with large artery atherosclerosis IS subtypes. In addition, the results also indicated that the ε4 allele related to undetermined IS and ε4/ε4 genotype was related to small vessel disease IS. Compared with subjects with non-ε4-containing genotypes, the total cholesterol (TC) and low-density lipoprotein (LDL) level in blood and the proportion of cardiopath history were higher in all subjects with ε4-containing genotypes. Besides, the triacylglycerides (TG) level in blood was higher in controls with ε4-containing genotypes. In conclusion, in a Northwest China Han population, APOE ε4 allele was associated with blood lipid level. The TC and LDL levels were the independent risk factors for IS. APOE was a risk gene for IS, but not independent, especially for large artery atherosclerosis IS.

Background and Purpose: According to the guidelines for acute ischemic stroke treatment, intravenous tissue plasminogen activator (IV-tPA) administration is the first line treatment and intraarterial thrombolysis (IA-Tx) with retrieval stent is regarded as additional treatment. But recanalization rate of large artery intracranial occlusion disease (LAICOD) after IV-tPA is very low and inconsistent according to the reports. Authors tried to find out the early recanalization rate of IV-tPA in patients with LAICOD. Methods: 278 with anterior circulation occlusion patients were included in this analysis. Brain CT-angiography (CTA) was an initial imaging study and acute stroke MRI was following after the IV-tPA. Recanalization rate was studied with initial CTA and followed MRA image. And other clinical outcomes were compared with IV-tPA, IA-Tx or perfusion/diffusion-mismatching (P/D-mismatching) or not. Results: The overall recanalization rate of LAICOD after IV-tPA was 15.5% (43/278), 86.0% (86/100) in patients treated with IA-Tx after IV-tPA, and 78.7% (48/61) in IA-Tx without IV-tPA. In patients who underwent IA-Tx after IV-tPA, P/D-mismatching patients showed higher recanalization rate (88.2% = 67/76 vs. 66.7% = 16/27, p = 0.020), and higher incidence of favorable outcomes (63.2% = 48/76 vs. 12.5% = 3/27, p = 0.000) compared to P/D-matching patients. Conclusion: This study suggests that recanalization rate after IV-tPA for the patients with acute ischemic stroke due to LAICOD is very low and IV-tPA before IA-Tx does not significantly influence on the neurologic outcomes and complication rates. Bridging treatment is effective, for stroke patient management, but authors would like to propose that IA-Tx might be applied as the first therapy option, just like in the management of acute myocardial infarction patients.

Aim: We sought to determine whether the extent of chronic white matter hyper-intensities (WMH) and white matter hypo-perfusion (WMHP), as markers of cerebral small vessel disease (CSVD), were associated with poor collateral flow in acute ischemic stroke as a potential cause of unfavorable functional outcome. Methods: Acute ischemic stroke patients within 12 hours of symptom onset with complete baseline and follow-up clinical data, who: (1) had large vessel occlusion in anterior circulation, (2) underwent baseline perfusion CT (CTP), (3) had 24-hour MRI were prospectively recruited. The volume of WMH was measured in the unaffected hemisphere on MRI semi-automatically. WMHP was measured as Delay Time (DT)>2s in white matter of unaffected hemisphere on CTP. Quality of Collateral flow was defined by the volume ratio of DT>3s/DT>6s on CTP. Unfavorable functional outcome was 90-day modified Rankin Scale (mRS)>2. The association between volumes of WMH, WMHP, and collateral flow were evaluated using univariate and multivariate generalized linear models. We also assessed the relationship between WMH, WHMP, and functional outcome with logistic regression. Results: There were 96 (66.6±12.81 years old, 35 female) ischemic stroke patients, and 51 were due to large artery atherosclerosis (LAA). In all patients, after multivariate adjustment, WMH volume (5.6±7.11ml) did not correlate with collateral flow (coefficient -0.01, 95% CI -0.03 to 0, P=0.09), although it was marginally associated with unfavorable outcome (Odds Ratio: 1.08, p=0.06, 95% CI 1 to 1.17). In all patients, WMHP volume (8.6±8.54ml) did not correlate with collateral flow (coefficient -0.01, 95% CI -0.01 to 0, P=0.29). However, in the LAA subgroup, WMH volume was strongly related to poorer collateral flow, i.e. lower DT>3s/DT>6s ratio(coefficient -0.03, 95% CI -0.04 to -0.01, P=0.01). WMHP volume was also correlated with poor collateral flow (coefficient -0.01, 95% CI -0.02 to 0, P=0.02). Conclusion: CSVD may contribute to poor collateral flow in acute stroke, especially in patients with LAA. This potentially explains the association between CSVD and poor acute stroke outcomes.

Objective. To explore the associations between type 2 diabetes mellitus (DM) and stroke by evaluating the clinical risk factors, characteristics, and outcomes of acute ischemic stroke (AIS) patients with and without type 2 DM. Methods. A total of 1,156 AIS patients (including 410 with type 2 DM (AIS-DM group)) and 746 without type 2 DM (AIS-NDM group)) were included. Patients’ demographics, auxiliary examinations, clinical manifestations, and treatment outcomes were recorded and analyzed. Results. Among the included AIS patients, 35.46% had type 2 DM. The AIS-DM group had less males (59.76% versus 70.64%), less smokers (33.90% versus 41.96%), more patients with hypertension (72.93% versus 63.94%; p = 0.002 ), higher triglyceride levels (42.93% versus 25.08%; p ≤ 0.01 ), and lower total cholesterol (147.06 mg/dl versus 175.31 mg/dl) than the AIS-NDM group. The proportion of patients with large artery atherosclerosis (LAA) in the AIS-DM group was lower (77.56% versus 85.92%; p < 0.05 ) than that in the AIS-NDM group, and the proportion of patients with small arterial occlusions (SAO) in the AIS-DM group was higher (27.07% versus 13.67%; p < 0.05 ) than that in the AIS-NDM group. The mean National Institutes of Health Stroke Scale (NIHSS) score at admission in the AIS-DM group was lower than that in the AIS-NDM group (4.39 versus 5.00; p = 0.008 ), but there was no significant difference in the NIHSS score or the modified Rankin Scale score between the two groups at discharge. A total of 85 AIS patients underwent intravenous thrombolysis treatment with recombinant tissue plasminogen activator (rtPA). The door-to-needle time (DNT) did not differ significantly between the groups (49.39 ± 30.40 min versus 44.25 ± 15.24 min; p = 0.433 ). In addition, there were no significant differences in the baseline NIHSS score, 7-day NIHSS score, and mRS score at discharge between the groups. After intravenous thrombolysis with rtPA, the AIS-NDM group had better recovery (44.30% versus 29.20%; p = 0.017 ) and a higher ratio of good treatment outcome at discharge (65.60% versus 54.20%; p = 0.762 ). Conclusions. Type 2 DM is associated with AIS and its risk factors, such as dyslipidemia and hypertension. Patients in the AIS-DM group had less LAA and smaller arterial occlusions, and DM could exacerbate the short-term clinical outcomes in AIS patients.
