Alberta Stroke Program Early Computed Tomography Score, Infarct Core Volume, and Endovascular Therapy Outcomes in Patients With Large Infarct: A Secondary Analysis of the ANGEL-ASPECT Trial.

Importance: Endovascular therapy (EVT) demonstrated better outcomes compared with medical management in recent randomized clinical trials (RCTs) of patients with large infarct. Objective: To compare outcomes of EVT vs medical management across different strata of the Alberta Stroke Program Early Computed Tomography Score (ASPECTS) and infarct core volume in patients with large infarct. Design, Setting, and Participants: This prespecified secondary analysis of subgroups of the Endovascular Therapy in Acute Anterior Circulation Large Vessel Occlusive Patients With a Large Infarct Core (ANGEL-ASPECT) RCT included patients from 46 stroke centers across China between October 2, 2020, and May 18, 2022. Participants were enrolled within 24 hours of symptom onset and had ASPECTS of 3 to 5 or 0 to 2 and infarct core volume of 70 to 100 mL. Patients were divided into 3 groups: ASPECTS of 3 to 5 with infarct core volume less than 70 mL, ASPECTS of 3 to 5 with infarct core volume of 70 mL or greater, and ASPECTS of 0 to 2. Interventions: Endovascular therapy or medical management. Main Outcomes and Measures: The primary outcome was the ordinal 90-day modified Rankin Scale (mRS) score. Results: There were 455 patients in the trial; median age was 68 years (IQR, 60-73 years), and 279 (61.3%) were male. The treatment effect did not vary significantly across the 3 baseline imaging subgroups (P = .95 for interaction). The generalized odds ratio for the shift in the 90-day mRS distribution toward better outcomes with EVT vs medical management was 1.40 (95% CI, 1.06-1.85; P = .01) in patients with ASPECTS of 3 to 5 and infarct core volume less than 70 mL, 1.22 (95% CI, 0.81-1.83; P = .23) in patients with ASPECTS of 3 to 5 and infarct core volume of 70 mL or greater, and 1.59 (95% CI, 0.89-2.86; P = .09) in patients with ASPECTS of 0 to 2. Conclusions and Relevance: In this study, no significant interaction was found between baseline imaging status and the benefit of EVT compared with medical management in patients with large infarct core volume. However, estimates within subgroups were underpowered. A pooled analysis of large core trials stratified by ASPECTS and infarct core volume strata is warranted.

Unsuccessful Recanalization versus Medical Management of Patients with Large Ischemic Core : Analysis of the ANGEL-ASPECT Randomized Trial.

PURPOSE: The outcomes of patients with large ischemic core who fail to recanalize with endovascular therapy (EVT) compared to medical management (MM) are uncertain. The objective was to evaluate the clinical and safety outcomes of patients who underwent EVT in patients with large ischemic core and unsuccessful recanalization. METHODS: This was a post hoc analysis of the ANGEL-ASPECT randomized trial. Unsuccessful recanalization was defined as patients who underwent EVT with eTICI 0-2a. The primary endpoint was 90-day very poor outcome (mRS 5-6). Multivariable logistic regression was conducted controlling for ASPECTS, occlusion location, intravenous thrombolysis, and time to treatment. RESULTS: Of 455 patients 225 were treated with MM. Of 230 treated with EVT, 43 (19%) patients had unsuccessful recanalization. There was no difference in 90-day very poor outcomes (39.5% vs. 40%, aOR 0.93, 95% confidence interval, CI 0.47-1.85, p = 0.95), sICH (7.0% vs. 2.7%, aOR 2.81, 95% CI 0.6-13.29, p = 0.19), or mortality (30% vs. 20%, aOR 1.65, 95% CI 0.89-3.06, p = 0.11) between the unsuccessful EVT and MM groups, respectively. There were higher rates of ICH (55.8% vs. 17.3%, p < 0.001), infarct core volume growth (142.7 ml vs. 90.5 ml, ß = 47.77, 95% CI 20.97-74.57 ml, p < 0.001), and decompressive craniectomy (18.6% vs. 3.6%, p < 0.001) in the unsuccessful EVT versus MM groups. CONCLUSION: In a randomized trial of patients with large ischemic core undergoing EVT with unsuccessful recanalization, there was no difference in very poor outcomes, sICH or death versus medically managed patients. In the unsuccessful EVT group, there were higher rates of any ICH, volume of infarct core growth, and decompressive craniectomy.

Clinical characteristics and prognosis in oldest old patients with ischaemic stroke or transient ischaemic attack in China.

BACKGROUND: Limited data are available about the prognosis of ischaemic stroke or transient ischaemic attack (TIA) in oldest-old patients, especially in China. We aimed to describe the clinical characteristics and prognosis of oldest-old patients with ischaemic stroke or TIA in China. METHODS: Patients with acute ischaemic stroke (AIS) or TIA were recruited between August 2015 and March 2018 in the Third China National Stroke Registry (CNSR-III). Clinical characteristics including demographic data, medical history, medication use and stroke aetiology, were obtained. The outcomes were one-year stroke recurrence, combined vascular events (stroke, myocardial infarction, and cardiovascular death), mortality, and poor functional outcome [modified Rankin scale (mRS) 3-6]. Oldest-old was defined as ≥80 years old. Clinical characteristics and prognosis were compared by different age groups (<65, 65-79, and ≥80 years). The association between age and prognosis was analysed using the multivariable Cox proportional hazards and logistic regression models. RESULTS: A total of 15,166 patients with AIS or TIA were included in this study with 929 (6.13%) oldest-old patients. Oldest-old patients had a higher likelihood of cardioembolic stroke or comorbid cardiac disease than other age groups. When compared with patients aged <65 years, oldest-old patients had higher risk of one-year stroke recurrence [adjusted hazard ratio (HR) 1.36; 95% confidence interval (CI): 1.06-1.73, P=0.014], combined vascular events [adjusted HR, 1.42; 95% CI, 1.13-1.79, P=0.003], mortality [adjusted odds ratio (OR), 4.25; 95% CI: 2.99-6.04, P<0.001] and poor functional outcome (adjusted OR, 4.25; 95% CI: 3.40-5.33, P<0.001) with P for trends <0.001 among age groups. CONCLUSIONS: Oldest-old patients differed from younger patients regarding clinical characteristics, stroke aetiology, and secondary preventive medication persistence with a poor clinical prognosis in China. Current information on profile of the oldest-old stroke patients is crucial to develop specific secondary prevention and treatment strategies.

Treating depressive disorders with the Unified Protocol: A preliminary randomized evaluation.

OBJECTIVES: This study aims to examine the efficacy of the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP) for individuals diagnosed with a depressive disorder. METHOD: Participants included 44 adults who met criteria for major depressive disorder, persistent depressive disorder, or another specified depressive disorder according to the Anxiety Disorder Interview Schedule (ADIS). These individuals represent a subset of patients from a larger clinical trial comparing the UP to single-disorder protocols (SDPs) for discrete anxiety disorders and a waitlist control (WLC) condition (Barlow et al., 2017); inclusion criteria for the parent study required participants to have a principal anxiety disorder. RESULTS: Significant reductions in depressive symptoms were observed within the UP condition across clinician-rated and self-report measures of depression from baseline to post-treatment, as well as to the 12-month follow-up assessment. Compared to the WLC group, individuals in the UP condition demonstrated significantly lower levels on our continuous, clinician-rated measure of depressive symptoms at post-treatment. There were no differences between the UP and SDP conditions on depressive symptoms at post-treatment or at the 12-month follow-up timepoint. CONCLUSIONS: In this exploratory set of analyses, the UP evidenced efficacy for reduction of depressive symptoms, adding to the growing support for its utility in treating depression.
