Early Hospital Arrival After Acute Ischemic Stroke Is Associated With Family Members' Knowledge About Stroke

Background and Purpose: Prehospital delay is the major factor limiting intravenous thrombolysis and mechanical thrombectomy in acute ischemic stroke (AIS). This study aimed to: (1) identify factors related to prehospital delay and (2) determine the impact of recognition and behavior of family members on patient delay.Methods: A cross-sectional, multicenter study was conducted at six teaching hospitals in China between December 1, 2018 and November 30, 2019. Patients who experienced AIS within 7 days of onset were interviewed.Results: Of 1,782 consecutive patients (male, 57.97%; mean age, 66.3 ± 9.65 years) who had an AIS, 267 (14.98%) patients arrived within 4.5 h and 722 (40.52%) patients arrived within 6 h of stroke onset. Among patients who arrived within 4.5 h, 103 (38.6%) received thrombolysis. Age over 65 years (OR, 2.009; 95% CI, 1.014–3.982), prior stroke (OR, 3.478; 95% CI, 1.311–9.229), blurred vision (OR, 3.95; 95% CI, 1.71–9.123), and patients deciding to seek medical help (OR, 3.097; 95% CI, 1.417–6.769) were independently associated with late arrival. In contrast, sudden onset of symptoms (OR, 0.075; 95% CI, 0.028–0.196), the National Institutes of Health Stroke Scale 7–15 (OR, 0.093; 95% CI, 0.035–0.251), consciousness disturbance (OR, 0.258; 95% CI, 0.091–0.734), weakness (OR, 0.265; 95% CI, 0.09–0.784), arrival by ambulance (OR, 0.102; 95% CI, 0.049–0.211), decision time <30 min (OR, 0.008; 95% CI, 0.003–0.018), and family member understanding stroke requires early treatment (OR, 0.224; 95% CI, 0.109–0.462) were independently associated with early arrival.Conclusions: The prehospital delay in China lags behind Western countries. Recognition and behavior of stroke patients' family members may play a key role in early arrival.

The Impact

Introduction: Given the recent positive endovascular therapy trials for acute ischemic stroke (AIS), this therapeutic strategy is now being increasingly incorporated into routine clinical practice. Identifying prognostic factors among AIS patients receiving endovascular revascularization treatments (ERT) in the real world could be important for clinicians and patients. While the impact of diabetes mellitus (DM) on IV thrombolytic outcomes after AIS has been extensively investigated, there is a paucity of data assessing effects of DM on ERT outcomes after AIS. We evaluated the impact of comorbid DM on ERT for AIS. Methods: From Jan 2011 to Feb 2016, patients with AIS who underwent ERT for cervicocephalic occlusions were consecutively enrolled into the Acute Stroke due to Intracranial Atherosclerotic occlusion and Neurointervention - Korean Retrospective (ASIAN KR) registry from 3 hospitals. Patients were excluded if onset to puncture time over 8 hours, in-hospital stroke, or unavailable 3-month mRS. DM was diagnosed if a patient had the history, or hemoglobin A1c on admission was over 6.5. Univariate analysis was performed to compare the characteristics between DM and non-DM population. Multiple logistic regression analysis was used to validate the effect of comorbid DM on 3 month outcomes. Results: Of 721 patients, 667 (93%) were finally included, with 233 DM patients and 434 non-DM patients. In the univariate analysis, comorbidity with hypertension (71.2% vs. 58.3%, p=0.001) and dyslipidemia (36.7% vs. 26.7%, p=0.012) were more frequent in the DM population. Periprocedural factors such as target vessels, intravenous thrombolysis, and final reperfusion grades did not differ. Good outcomes with mRS 0-2 were less frequent in the DM population (43.3% vs. 53.7%, p=0.011). In the logistic regression analysis adjusting age, male sex, initial NIHSS, premorbid mRS, hypertension history, atrial fibrillation, intravenous thrombolysis, onset to puncture time and successful reperfusion, DM was an independent predictor of poor outcomes (mRS 3-6; 1.933, 1.274-2.933, p=0.002). Conclusion: In patients receiving ERT for AIS due to cervicocephalic artery occlusions, the presence of DM as a comorbidity confers greater odds of a poor functional outcome.

The Impact

ABSTRACT Stroke is the leading cause of long term disability in developed countries and one of the top causes of mortality worldwide. The past decade has seen substantial advances in the diagnostic and treatment options available to minimize the impact of acute ischemic stroke. The key first step in stroke care is early identification of patients with stroke and triage to centers capable of delivering the appropriate treatment, as fast as possible. Here, we review the data supporting pre-hospital and emergency stroke care, including use of emergency medical services protocols for identification of patients with stroke, intravenous thrombolysis in acute ischemic stroke including updates to recommended patient eligibility criteria and treatment time windows, and advanced imaging techniques with automated interpretation to identify patients with large areas of brain at risk but without large completed infarcts who are likely to benefit from endovascular thrombectomy in extended time windows from symptom onset. We also review protocols for management of patient physiologic parameters to minimize infarct volumes and recent updates in secondary prevention recommendations including short term use of dual antiplatelet therapy to prevent recurrent stroke in the high risk period immediately after stroke. Finally, we discuss emerging therapies and questions for future research.

Abstract Background: It is well known that red blood cell distribution width(RDW)is a parameter reflecting the heterogeneity of red blood cell volume，which recently may be associated with the development of cardiovascular events or mortality in patients after myocardial infarction .However, little is known about the association between RDW and stroke, especially regarding indisputable endpoints such as death. The purpose of the study was to explore the prognostic value of RDW and its effect on mortality among patients with acute ischemic stroke (AIS) undergoing Intravenous thrombolysis (IVT). Methods: We carried out retrospective analysis of acute anterior ischemic strokes cases treated with IVT between January 2016 and March 2018.The effect of RDW on poor outcome (modified Rankin score 3-6) and mortality in 1 year were assessed. Use multivariate logistic regression to explore the predictors. Receiver operating characteristic (ROC) curve was used to evaluate the predictive capability of variables, furthermore, we applied Cox proportional-hazards models to analyze the impact of factors on survival. Results: RDW (Multivariate OR 1.179;95%CI 0.900-1.545,p=0.232) was not associated with clinical outcome. Surviving patients have lower baseline RDW compared with patients who later died. Adding RDW to NIHSS could improve the prediction of the mortality of stroke clinical outcomes. Conclusions: The finding of our study implied that higher RDW was a potential predictive factor of mortality in 1 year in patients with AIS undergoing IVT，but RDW might not be associated with worse survival function among stroke survivors.

The Impact

Background: Sex differences in the structural connectome of the brain are clinically highly relevant, but they have mostly been neglected in stroke trials. We investigated the impact of the interaction sex-by-hemisphere on outcome in stroke patients after intravenous thrombolysis (IVT). Methods: This is an observational study based on consecutively collected supratentorial stroke patients treated with IVT (n = 1,231). The 3-month modified Rankin scale (mRS) was estimated by adjusted binary (mRS 0-2 for good outcome) and ordinal regression analysis. As baseline characteristics differ substantially between the sexes, we aimed for better covariate balance by employing coarsened exact matching. Results: Sex-by-hemisphere predicted good outcome in the entire cohort (726 left, 505 right hemispheric strokes, p valueinteraction 0.032) and in the matched cohort (338 left, 273 right, p valueinteraction 0.003). Ordinal regression suggested a comparable estimate in the matched cohort (p valueinteraction 0.006). Further investigation revealed relevant between-sex and within-sex risk: right hemispheric strokes in men were 1.54 times (95% confidence intervals (CIs) 1.15-2.01) more likely than in women to achieve mRS 0-2. Women with right hemispheric strokes were 0.72 times (95% CI 0.54-0.92) less likely to reach mRS 0-2 than women with left hemispheric strokes. Conversely, men with right hemispheric strokes were 1.35 times (95% CI 1.06-1.70) more likely to achieve mRS 0-2 than men with left hemispheric strokes. Conclusion: This study suggests that outcomes are different in both sexes after IVT when different hemispheres are affected. Further consideration of this hypothesis in clinical trials might help in guiding individualized, injury-specific treatment approaches for acute ischemic stroke.

ObjectiveTo assess the impact of diabetes on neurological outcome and recanalization in acute ischemic stroke (AIS) after intravenous thrombolysis (IVT).MethodsClinical data of 419 consecutive patients with AIS who received IVT between June 2009 and April 2014. Based on the medical history and new diagnosis, the patients were divided into groups with and without diabetes. Neurological outcomes at 24 h, 7 days and 3 months after IVT were evaluated. Favorable outcome was defined as National Institutes of Health Stroke Scale (NIHSS) score decrease ≥4 points from baseline or 0 at 24 h, NIHSS decrease ≥8 points or 0 at day 7, or modified Rankin scale ≤1 at 3 months after IVT. Recanalization on non-invasive imaging was evaluated in patients with large vessel occlusion (LVO) according to thrombolysis in myocardial infarction grades.ResultsAmong 419 patients, 98 (23.4%) had diabetes. Multivariable analyses showed that comorbidity of diabetes was an independent predictor of unfavorable outcome at 24 h (OR=0.534, 95% CI 0.316 to 0.903, p=0.019), at day 7 (OR=0.382, 95% CI 0.220 to 0.665, p=0.001), and at 3 months (OR=0.464, 95% CI 0.266 to 0.808, p=0.007). In patients with LVO, diabetes was an independent predictor of incomplete recanalization 24 h after IVT (OR=0.268, 95% CI 0.075 to 0.955, p=0.042).ConclusionsDiabetic patients with AIS had unfavorable neurological outcome, potentially linked to incomplete recanalization after IVT.
