Background Anemia or low hemoglobin can increase the risk of stroke. However, the association between hemoglobin and outcomes after stroke is uncertain. In this study, we aimed to investigate the association between hemoglobin and clinical outcomes, including mortality, poor functional outcome, stroke recurrence, and composite vascular events at 1 year. Methods and Results We included the patients diagnosed with acute ischemic stroke or transient ischemic attack from the Third China National Stroke Registry. We used the Cox model for mortality, stroke recurrence, and composite vascular events and the logistic model for the poor functional outcome to examine the relationship between hemoglobin and clinical outcomes. In addition, we used the restricted cubic spline to evaluate the nonlinear relationship. This study included 14 159 patients with acute ischemic stroke or transient ischemic attack. After adjusted for potential cofounders, both anemia and high hemoglobin were associated with the higher risk of mortality (hazard ratio [HR], 1.73; 95% CI, 1.39–2.15; HR, 2.71; 95% CI, 1.95–3.76) and poor functional outcome (odds ratio [OR], 1.36; 95% CI, 1.18–1.57; OR, 1.42; 95% CI, 1.07–1.87). High hemoglobin, but not anemia, increased the risk of stroke recurrence (HR, 1.37; 95% CI, 1.05–1.79) and composite vascular events (HR, 1.41; 95% CI, 1.08–1.83). There was a U‐shaped relationship between hemoglobin and mortality and poor functional outcome. Conclusions Abnormal hemoglobin was associated with a higher risk of all‐cause mortality, poor functional outcome, stroke recurrence, and composite vascular events. More well‐designed clinical studies are needed to confirm the relationship between hemoglobin and clinical outcomes after stroke.

Abstract Backgrounds: Single attempt of stent retrieval during endovascular thrombectomy (EVT) seems to be associated with favorable clinical outcomes of patients with acute ischemic stroke (AIS), but the relationship between single attempt and clinical outcomes or complications have not been characterized. In addition, the factors related to single retrieval attempts during EVT are undefined. Here, we investigated the relationship between single attempt of stent retrieval and the clinical outcomes or complications after EVT, and further investigated the factors associated with single attempt of stent retrieval in AIS patients. Methods: This study enrolled consecutive patients with AIS treated by EVT with second-generation stent retriever devices from April 2016 to April 2019. Attempts of EVT were classified as single or multiple attempts of stent retrieval after filtrating all enrolled patients based on inclusion and exclusion criteria. We analyzed the clinical outcomes and complications between single attempt of stent retrieval and multiple attempts of stent retrieval, and the factors independently associated with a single attempt were identified through logistical regression analysis. Results: We enrolled 143 patients, including 69 patients with single attempt of stent retrieval and 74 patients with multiple attempts of stent retrieval. More patients with single attempt of stent retrieval reached favorable clinical outcomes ( p =0.016; adjusted OR [95%CI]: 2.652 [1.204-5.843] ), and patients with single attempts of stent retrieval showed as a lower incidence of symptomatic intracranial hemorrhage (sICH) ( p =0.046; adjusted OR [95%CI]: 0.192 [0.038-0.973] ). Diabetes mellitus ( p =0.026; adjusted OR [95%CI]: 2.871 [1.137-7.249] ) was independently associated with single attempt of EVT with stent retrieval. Conclusions: Single attempt of stent retrieval during EVT can decrease incidence of sICH and improve favorable clinical outcomes of patients with AIS. Those with diabetes mellitus may be more prone to single attempt of stent retrieval during EVT .

AbstractEndovascular treatment (EVT) has been accepted as the standard of care for patients with acute ischemic stroke. The aim of the present study was to compare clinical outcomes of patients who received EVT within and beyond 6 h from symptom onset to groin puncture without perfusion software in Guangdong district, China. Between March 2017 and May 2018, acute ischemic stroke patients who received EVT from 6 comprehensive stroke centers, were enrolled into the registry study. In this subgroup study, we included all patients who had acute proximal large vessel occlusion in the anterior circulation. The demographic, clinical and neuroimaging data were collected from each center. A total of 192 patients were included in this subgroup study. They were divided into two groups: group A (n = 125), within 6 h; group B (n = 67), 6–24 h from symptom onset to groin puncture. There were no substantial differences between these two groups in terms of 90 days favorable outcome (modified Rankin scale [mRS] ≤ 2, P = 0.051) and mortality (P = 0.083), and the risk of symptomatic intracranial hemorrhage at 24 h (P = 0.425). The NIHSS (median 16, IQR12-20, group A; median 12, IQR8-18, group B; P = 0.009) and ASPECTS (median 10, IQR8-10, group A; median 9, IQR8-10, group B; P = 0.034) at baseline were higher in group A. The anesthesia method (general anesthesia, 21.3%, group A vs. 1.5% group B, P = 0.001) were also statistically different between the two groups. The NIHSS and ASPECTS were higher, and general anesthesia was also more widely used in group A. Clinical outcomes were not significantly different within 6 h versus 6–24 h from symptom onset to groin puncture in this real world study.

Abstract Background It has been shown that eosinophils are decreased and monocytes are elevated in patients with acute ischemic stroke (AIS), but the impact of eosinophil-to-monocyte ratio (EMR) on clinical outcomes among AIS patients remains unclear. We aimed to determine the relationship between EMR on admission and 3-month poor functional outcome in AIS patients. Methods A total of 521 consecutive patients admitted to our hospital within 24 h after onset of AIS were prospectively enrolled and categorized in terms of quartiles of EMR on admission between August 2016 and September 2018. The endpoint was the poor outcome defined as modified Rankin Scale score of 3 to 6 at month 3 after admission. Results As EMR decreased, the risk of poor outcome increased (p < 0.001). Logistic regression analysis revealed that EMR was independently associated with poor outcome after adjusting potential confounders (odds ratio, 0.09; 95% CI 0.03–0.34; p = 0.0003), which is consistent with the result of EMR (quartile) as a categorical variable (odds ratio, 0.23; 95% CI 0.10–0.52; ptrend < 0.0001). A non-linear relationship was detected between EMR and poor outcome, whose point was 0.28. Subgroup analyses further confirmed these associations. The addition of EMR to conventional risk factors improved the predictive power for poor outcome (net reclassification improvement: 2.61%, p = 0.382; integrated discrimination improvement: 2.41%, p < 0.001). Conclusions EMR on admission was independently correlated with poor outcome in AIS patients, suggesting that EMR may be a potential prognostic biomarker for AIS.

Background: Mechanical thrombectomy is the standard therapy in patients with acute ischemic stroke (AIS). The primary aim of our study was to compare the procedural efficacy of the direct aspiration technique, using Penumbra ACETM aspiration catheter, and the stent retriever technique, with a SolitaireTM FR stent. Secondarily, we investigated treatment-dependent and treatment-independent factors that predict a good clinical outcome. Methods: We analyzed our series of mechanical thrombectomies using a SolitaireTM FR stent and a Penumbra ACETM catheter. The clinical and radiographic data of 76 patients were retrospectively reviewed. Using binary logistic regression, we looked for the predictors of a good clinical outcome. Results: In the Penumbra ACETM group we achieved significantly higher rates of complete vessel recanalization with lower device passage counts, shorter recanalization times, shorter procedure times and shorter fluoroscopy times (p < 0.001) compared to the SolitaireTM FR group. We observed no significant difference in good clinical outcomes (52.4% vs. 56.4%, p = 0.756). Predictors of a good clinical outcome were lower initial NIHSS scores, pial arterial collateralization on admission head CT angiography scan, shorter recanalization times and device passage counts. Conclusions: The aspiration technique using Penumbra ACETM catheter is comparable to the stent retriever technique with SolitaireTM FR regarding clinical outcomes.

The Relationship

Introduction: Cerebral small vessel diseases (SVDs) i.e. white matter lesion and cerebral microbleeds (CMBs) are related to the patients with stroke more deeply than those without. In general population, in addition to age, hypertension, diabetes chronic kidney diseases (CKD) is well known to be related to SVDs, but it remains unclear in patients with stroke. We investigated the relationship between CKD and the presence of SVDs in patients with acute ischemic stroke. Methods: We enrolled 493 patients with acute ischemic stroke patients or transient ischemic attack patients (mean age 71; 60% male) who had undergone 1.5T MR imaging within a week of the index events from April 2013 to march 2015. We evaluated kidney function by estimated glomerular filtration rate (eGFR) with the modification of diet in Renal Disease. CKD was defined as an eGFR less than 60mil/min/1.73m 2 . CMBs were defined as focal areas of very low signal intensity smaller than 10mm. White matter lesion as Periventricular hyper intensity (PVH)>grade 2 and Deep and Subcortical White Matter Hyper intensity (DSWMH)> grade 2 were defied as advanced PVH and advanced DSWMH, respectively. We investigated relationship between CKD and CMBs, advanced PVH and advanced DSWMH using a logistic regression analysis. Results: We noted CMBs in 173 patients (35%), PVH in 81 (16%), and DSWMH in 151 (31%). An univariate analysis revealed that the age, CKD, history of stroke, and antiplatelet agents were associated with presence of CMBs, advanced PVH and severe DSWMH . The multivariate analysis revealed that CMBs, advanced PVH and advanced DSWMH were associated with age (CMBs: odds ratio(OR) ; 1.32 ; 95% confidence interval(CI), 1.10-1.60, p=0.004, advanced PVH : OR ; 3.00 ; 95% CI, 2.17-4.26, p<0.01, advanced DSWMH: OR ; 1.94; 95% CI, 1.56-2.45, p<0.01 ), history of stroke(CMBs : OR ; 2.01 ; 95% CI, 1.21-3.34, p=0.007, advanced PVH : OR ; 2.25 ; 95% CI, 1.18-4.27, p=0.01, advanced DSWMH: OR ; 1.78 ; 95% CI, 1.03-3.06, p=0.038). CKD was associated with CMBs (OR ; 1.62 ; 95% CI, 1.04-2.52, p=0.03), but PVH and DSWMH were not. Conclusions: It seems that age and history of stroke are related to CMBs, advanced PVH and advanced DSWMH, and that CKD is associates with CMBs but not with either advanced PVH or advanced DSWMH.

BackgroudThe goal of this study was to determine if the choice of imaging paradigm performed in the emergency department influences the procedural or clinical outcomes after mechanical thrombectomy (MT).MethodsThis is a retrospective comparative outcome study which was conducted from the ANGEL-ACT registry. Comparisons were made between baseline characteristics and clinical outcomes of patients with acute ischemic stroke undergoing MT with non-contrast head computed tomography (NCHCT) alone versus patients undergoing NCHCT plus non-invasive vessel imaging (NVI) (including CT angiography (with or without CT perfusion) and magnetic resonance angiography). The primary outcome was the modified Rankin Scale (mRS) score at 90 days. Secondary outcomes included change in mRS score from baseline to 90 days, the proportions of mRS 0–1, 0–2, and 0–3, and dramatic clinical improvement at 24 hours. The safety outcomes were any intracranial hemorrhage (ICH), symptomatic ICH, and mortality within 90 days.ResultsA total of 894 patients met the inclusion criteria; 476 (53%) underwent NCHCT alone and 418 (47%) underwent NCHCT + NVI. In the NCHCT alone group, the door-to-reperfusion time was shorter by 47 min compared with the NCHCT + NVI group (219 vs 266 min, P<0.001). Patients in the NCHCT alone group showed a smaller increase in baseline mRS score at 90 days (median 3 vs 2 points; P=0.004) after adjustment. There were no significant differences between groups in the remaining clinical outcomes.ConclusionsIn patients selected for MT using NCHCT alone versus NCHCT + NVI, there were improved procedural outcomes and smaller increases in baseline mRS scores at 90 days.
