Procedural Time

Background: Recent single center studies have suggested that “procedural time” independent of “time to procedure” can affect outcomes of acute ischemic stroke patients undergoing endovascular treatment (ET). We performed a pooled analysis from three ET trials to determine the effect of procedural time on angiographic and clinical outcomes. Objective: To determine the relationship between procedural time and clinical outcomes among acute ischemic stroke patients undergoing successful recanalization with ET. Methods: We analyzed data from SWIFT, STAR and SWIFT PRIME trials. Baseline demographic and clinical characteristics, NIHSS score on admission, intracranial hemorrhage rates and mRS at 3 months post procedure were analyzed. TICI scale was used to grade post procedure angiographic recanalization. Procedural time was defined by the time interval between groin puncture and recanalization. We estimated the procedural time after which favorable clinical outcome was unlikely even after recanalization (futile) after age and NIHSS score adjustment. Results: We analyzed 301 patients who underwent ET and had near complete or complete recanalization (TICI 2b or 3). The procedural time (±SD) was significantly shorter in patients who achieved a favorable outcome (mRS 0-2) compared with those who did not achieve favorable outcome (44±25 vs 51±33 minutes, p=0.04). Table 1. In the multivariate analysis (including all baseline characteristics with a p value <0.05 as independent variables), shorter procedural time was a significant predictor of lower odds of unfavorable outcome (OR 0.49, 95% CI 0.28, 0.85, p=0.012). The rates of favorable outcomes were significantly higher when the procedural time was <60 minutes compared with ≥60 minutes (62% vs 45%, p=0.020). Conclusion: Procedural time in patients undergoing mechanical thrombectomy for acute ischemic stroke is an important determinant of favorable outcomes in those with near complete or complete recanalization.

Introduction: Impaired hydration measured by elevated blood urea nitrogen (BUN) to creatinine ratio has been associated with worsened outcome after acute ischemic stroke. Whether hydration status is relevant for patients with acute ischemic stroke treated with mechanical thrombectomy remains unknown. Materials and Methods: We conducted a retrospective review of consecutive acute ischemic stroke patients who underwent endovascular procedures for anterior circulation large artery occlusion at Johns Hopkins Comprehensive Stroke Centers between 2012 and 2017. A volume contracted state (VCS), was determined based on surrogate lab markers and defined as blood urea nitrogen (BUN) to creatinine ratio greater than 15. Endpoints were achievement of successful revascularization (TICI 2b or 3), early re-occlusion, and short term clinical outcomes including development of early neurological worsening and functional outcome at 3 months. Results: Of the 158 patients who underwent an endovascular procedure, 102 patients had a final diagnosis of anterior circulation large vessel occlusion and met the inclusion criteria for analysis. Volume contracted state was present in 62/102 (61%) of patients. Successful revascularization was achieved in 75/102 (74%) of the cohort. There was no relationship between VCS and successful revascularization, but there was a 1.13 increased adjusted odds (95% CI 1.01, 1.27) of re-occlusion within 24 hours for every point higher BUN/creatinine ratio in the subset of patients who underwent radiological testing for pre-procedure planning (n=57). There was no relationship between VCS and clinical outcomes including early neurological worsening and 3 month outcome. Conclusions: Patients with VCS and large vessel anterior circulation stroke may have a higher odds of early re-occlusion after mechanical thrombectomy than their non-VCS counterparts, but no differences in successful revascularization nor clinical outcomes were present in this cohort. These results may suggest an opportunity for the exploration of pre-procedure hydration to improve outcomes.

ABSTRACT Aims: The aim of the study was to determine the effect of left ventricular ejection fraction on clinical outcomes of acute ischemic stroke patients. Study Design: This study design was a prospective cohort observational study. Place and Duration of Study: This study was conducted at Stroke Unit, Neurology Ward, and Cardiology Ward at the Dr. Sardjito Hospital, Yogyakarta, Indonesia, between July and December 2016. Materials and Methods: Hospitalized acute ischemic stroke patients were recruited, with sample was taken by consecutive sampling until reaching amount fulfilling inclusion criterion was 62 persons. In this study, clinical outcomes were measured by National Institutes of Health Stroke Scale (NIHSS) scores as well as dependent variables and left ventricular ejection fraction as independent variables. Logistic regression analyses were performed to discover any potential independent variable that can influence the left ventricular ejection fraction role at the clinical outcomes with NIHSS scores. Results: Multivariate analyses revealed that several variables were significantly interacted with the influence of left ventricular ejection fraction at the clinical outcomes with NIHSS scores. These variables were the left ventricular ejection fraction <48% (95% confidence interval [CI]: 0.691–0.925; P = 0.001), left ventricular ejection fraction + low high-density lipoprotein (HDL) (95% CI: 0.73–0.949; P = 0,001), left ventricular ejection fraction + diabetes mellitus (DM) (95% CI: 0.799–0.962; P = 0,001), and left ventricular ejection fraction + low HDL + DM (95% CI: 0.841–0.98; P = 0,001). Conclusion: The influence of the lower left ventricular ejection fraction to clinical outcome of ischemic stroke patients has a worsening of neurological deficit outcome by considering the combination of several independent variables including the DM and low HDL.

Effect Of Age

BackgroundPatient age and baseline Alberta Stroke Program Early CT score (ASPECTS) are both independent predictors of outcome in acute ischemic stroke patients treated with endovascular therapy (EVT). We assessed the combined effect of age and ASEPCTS on clinical outcome in acute ischemic stroke patients with LVO with and without EVT, and EVT treatment effect in different age/ASPECTS subgroups.MethodsThe HERMES collaboration pooled data of seven randomized controlled trials that tested the efficacy of EVT. Adjusted logistic regression was performed to test for multiplicative interaction of age and ASPECTS with the primary outcome (ordinal mRS) and secondary outcomes (mRS 0–2/0–1/0–3) in the EVT and control arms. Patients were then stratified by age (<75 vs ≥75 years) and ASPECTS (0–5/6–7/8–10), and adjusted effect-size estimates for the association of EVT were derived for the six age/ASPECTS subgroups.Results1735 patients were included in the analysis. There was no multiplicative interaction between age and ASPECTS on clinical outcomes. In the exploratory subgroup analysis, we found a nominally negative point estimate for the association of EVT with clinical outcome in the ASPECTS 0–5/age ≥75, subgroup (acOR 0.36, 95% CI 0.07 to 1.89). The point estimate for moderate outcome (mRS0-3) nominally favored EVT (aOR 1.24, 95% CI 0.16 to 9.84). In all other subgroups, effect size-estimates consistently favored EVT.ConclusionThere was no multiplicative interaction of age and ASPECTS on clinical outcomes in EVT or control arm patients. Outcomes in patients ≥75 years with ASPECTS 0–5 were poor, irrespective of treatment. Further investigation to define the role of EVT and range of acceptable outcomes in this subgroup is warranted.
