    Abstract: It is unclear whether patients with different stroke/transient ischemic attack etiologies benefit differently from gene-directed dual antiplatelet therapy. This study explored the efficacy and safety of ticagrelor-aspirin versus clopidogrel-aspirin in transient ischemic attack or minor stroke with different causes in the CHANCE-2 trial (Clopidogrel in High-Risk Patients With Acute Nondisabling Cerebrovascular Events-II). METHODS: This was a prespecified analysis of the CHANCE-2 trial, which enrolled 6412 patients with minor stroke or transient ischemic attack who carried CYP2C19 loss-of-function alleles. Patients with centralized evaluation of TOAST (Trial of ORG 10172 in Acute Stroke Treatment) classification of large-artery atherosclerosis, small-vessel occlusion, and stroke of undetermined cause were included. The primary efficacy outcome was new stroke, and the primary safety outcome was severe or moderate bleeding, both within 90 days. Cox proportional hazards models were used to assess the interaction of TOAST classification with the effects of dual antiplatelet therapy with ticagrelor-aspirin versus clopidogrel-aspirin. RESULTS: A total of 6336 patients were included in this study. In patients administered ticagrelor-aspirin and clopidogrel-aspirin, respectively, stroke recurred in 85 (9.8%) and 88 (10.7%) patients with large-artery atherosclerosis (hazard ratio, 0.86 [95% CI, 0.63–1.18]; P =0.34); 32 (3.6%) and 61 (7.0%) patients with small-vessel occlusion (hazard ratio, 0.51 [95% CI, 0.33–0.79]; P =0.002); and 68 (4.8%) and 87 (5.9%) patients with stroke of undetermined cause (hazard ratio, 0.80 [95% CI, 0.58–1.10]; P =0.17), with P =0.08 for the treatment×cause subtype interaction effect. There were no significant differences in severe or moderate bleeding events in patients with different cause and different treatment. CONCLUSIONS: In this prespecified analysis of the CHANCE-2 trial, the efficacy and safety of ticagrelor-aspirin versus clopidogrel-aspirin in preventing new stroke were consistent in patients with different causes. The influence of stroke cause on benefit of gene-guided antiplatelet therapy should be explored by further trials. REGISTRATION: URL: https://www.clinicaltrials.gov ; Unique identifier: NCT04078737.

    Abstract: In patients undergoing mechanical thrombectomy (MT), adjunctive antithrombotic might improve angiographic reperfusion, reduce the risk of distal emboli and reocclusion but possibly expose patients to a higher intracranial hemorrhage risk. This study evaluated the safety and efficacy of combined MT plus eptifibatide for acute ischemic stroke. Methods: This was a propensity-matched analysis of data from 2 prospective trials in Chinese populations: the ANGEL-ACT trial (Endovascular Treatment Key Technique and Emergency Workflow Improvement of Acute Ischemic Stroke) in 111 hospitals between November 2017 and March 2019, and the EPOCH trial (Eptifibatide in Endovascular Treatment of Acute Ischemic Stroke) in 15 hospitals between April 2019 and March 2020. The primary efficacy outcome was good outcome (modified Rankin Scale score 0–2) at 3 months. Secondary efficacy outcomes included the distribution of 3-month modified Rankin Scale scores and poor outcome (modified Rankin Scale score 5–6) and successful recanalization. The safety outcomes included any intracranial hemorrhage, symptomatic intracranial hemorrhage, and 3-month mortality. Mixed-effects logistic regression models were used to account for within-hospital clustering in adjusted analyses. Results: Eighty-one combination arm EPOCH subjects were matched with 81 ANGEL-ACT noneptifibatide patients. Compared with the no eptifibatide group, the eptifibatide group had significantly higher rates of successful recanalization (91.3% versus 81.5%; P =0.043) and 3-month good outcomes (53.1% versus 33.3%; P =0.016). No significant difference was found in the remaining outcome measures between the 2 groups. All outcome measures of propensity score matching were consistent with mixed-effects logistic regression models in the total population. Conclusions: This matched-control study demonstrated that MT combined with eptifibatide did not raise major safety concerns and showed a trend of better efficacy outcomes compared with MT alone. Overall, eptifibatide shows potential as a periprocedural adjunctive antithrombotic therapy when combined with MT. Further randomized controlled trials of MT plus eptifibatide should be prioritized.

    Abstract: Sex disparities in acute large vessel occlusion (LVO) following endovascular treatment (EVT) have been recently reported. However, there is uncertainty about the effect of sex differences on functional outcomes after EVT, particularly in an Asian population. The present study aimed to compare the clinical and safety outcomes between men and women with anterior circulation LVO treated with EVT. Methods: We analyzed data from the ANGEL-ACT (Endovascular Treatment Key Technique and Emergency Work Flow Improvement of Acute Ischemic Stroke: a Prospective Multicenter Registry Study) Registry, which was conducted at 111 hospitals from 26 provinces in China between November 2017 and March 2019. Men and women with anterior circulation LVO treated with EVT were matched using propensity scores. After a 1:1 propensity score matching, we compared the clinical outcomes including 90-day ordinal modified Rankin Scale distribution (primary outcome), procedure duration, successful reperfusion, symptomatic intracranial hemorrhage, and mortality. Furthermore, we explored sex modification on the primary outcome in subgroup analysis. Results: Of 1321 patients, 483 (36.6%) were women and 838 (63.4%) were men. The mean age for women and men were 68 and 62 years old, respectively. Among 578 patients identified after matching, there were no sex differences (men versus women) in 90-day ordinal modified Rankin Scale distribution (median [interquartile range], 4 [1–5] versus 3 [1–5], P =0.464), successful reperfusion (86.5% versus 91.0%, P =0.089), symptomatic intracranial hemorrhage (6.5% versus 7.9%, P =0.512), and mortality within 90 days (17.7% versus 17.0%, P =0.826). However, men had a longer median procedure duration than women (86 [52–128] versus 72 [48–110] minutes, β=14.51, [95% CI, 4.19–24.84]; P =0.006). Subgroup analysis showed that in patients with National Institutes of Health Stroke Scale score 〈 15, women tended to have a better outcome than men, whereas there was no gender effect in those with National Institutes of Health Stroke Scale score ≥15 ( P for interaction=0.032). Conclusions: Overall, this matched-control study from the ANGEL-ACT study showed similar clinical outcomes between men and women with anterior circulation LVO treated with EVT. However, in the subgroup of patients presenting with lower stroke severity (ie, National Institutes of Health Stroke Scale score 〈 15), women tended to have a better outcome than men highlighting a potential sex disparity for further investigation.

    Abstract: A recent randomized controlled trial DIRECT-MT (Direct Intra-Arterial Thrombectomy to Revascularize AIS Patients With Large Vessel Occlusion Efficiently in Chinese Tertiary Hospitals) compared the safety and efficacy of mechanical thrombectomy (MT) versus combined intravenous thrombolysis (IVT) and MT for acute large vessel occlusion. The current study utilized a prospective, nationwide registry to validate the results of the DIRECT-MT trial in a real-world practice setting. Methods: Subjects were selected from a prospective cohort of acute large vessel occlusion patients undergoing endovascular treatment at 111 hospitals from 26 provinces in China (ANGEL-ACT registry [Endovascular Treatment Key Technique and Emergency Work Flow Improvement of Acute Ischemic Stroke]) between November 2017 and March 2019. All patients eligible for IVT and receiving MT were reviewed and then grouped according to whether prior IVT or not (MT and combined IVT+MT). After a 1:1 propensity score matching, the outcome measures including the 90-day modified Rankin Scale, successful recanalization, door-to-puncture time, symptomatic intracranial hemorrhage, and intraprocedural embolization were compared. Results: A total of 1026 patients, 600 in the MT group and 426 in the combined group, were included. Among 788 patients identified after matching, there were no significant differences in the 90-day modified Rankin Scale (median, 3 versus 3 points; P =0.82) and successful recanalization (86.6% versus 89.3%; P =0.23) between the two groups; however, patients of the MT group had a shorter door-to-puncture time (median, 112 versus 136 minutes; β=−45.02 [95% CI, −68.31 to −21.74]), lower rates of symptomatic intracranial hemorrhage (5.5% versus 10.1%; odds ratio, 0.52 [95% CI, 0.30–0.91] ), and embolization (4.6% versus 8.1%; odds ratio, 0.54 [95% CI, 0.30–0.98]) than those of the combined group. Conclusions: This matched-control study largely confirmed the findings of the DIRECT-MT trial in a real-world practice setting, suggesting that MT may carry similar effectiveness to combined IVT+MT for acute large vessel occlusion patients, despite MT alone seems to be associated with a shorter in-hospital delay until procedure, lower risks of symptomatic intracranial hemorrhage, and embolization.

    Abstract: Whether imaging parameters would independently predict stroke recurrence in low-risk minor ischemic stroke (MIS) or transient ischemic attack (TIA) according to traditional score system (such as ABCD 2 score, which was termed on the basis of the initials of the five factors: age, blood pressure, clinical features, duration, diabetes) remains unclear. We sought to evaluate the association between imaging parameters and 1-year stroke recurrence in patients with TIA or MIS in different risk stratum stratified by ABCD 2 score. Methods: We included patients with TIA and MIS (National Institutes of Health Stroke Scale score ≤3) with complete baseline vessel and brain imaging data from the Third China National Stroke Registry III. Patients were categorized into different risk groups based on ABCD 2 score (low risk, 0–3; moderate risk, 4–5; and high risk, 6–7). The primary outcome was stroke recurrence within 1 year. Multivariable Cox proportional-hazards regression models were used to assess whether imaging parameters (large artery stenosis, infarction number) were independently associated with stroke recurrence. Results: Of the 7140 patients included, 584 patients experienced stroke recurrence within 1 year. According to the ABCD 2 score, large artery stenosis was associated with higher stroke recurrence in both low-risk (adjusted hazard ratio, 1.746 [95% CI, 1.200–2.540]) and moderate-risk group (adjusted hazard ratio, 1.326 [95% CI, 1.042–1.687] ) but not in the high-risk group ( P 〉 0.05). Patients with multiple acute infarctions or single acute infarction had a higher risk of recurrent stroke than those with no infarction in both low- and moderate-risk groups, but not in the high-risk group. Conclusions: Large artery stenosis and infarction number were independent predictors of 1-year stroke recurrence in low-moderate risk but not in high-risk patients with TIA or MIS stratified by ABCD 2 score. This finding emphasizes the importance of early brain and vascular imaging evaluation for risk stratification in patients with TIA or MIS.

    Abstract: The role of stroke etiology subtype in patients with acute large vessel occlusion on the occurrence of hemorrhagic transformation (HT) after endovascular treatment is poorly studied, and which factors mediate their relationship remains largely unknown. We utilized nationwide registry data to explore the association of stroke subtype (cardioembolism versus large artery atherosclerosis) with HT and to identify the possible mediators. Methods: A total of 1015 subjects were selected from the ANGEL-ACT registry (Endovascular Treatment Key Technique and Emergency Work Flow Improvement of Acute Ischemic Stroke)—a prospective consecutive cohort of acute large vessel occlusion patients undergoing endovascular treatment at 111 hospitals in China between November 2017 and March 2019—and divided into large artery atherosclerosis (n=538) and cardioembolism (n=477) according to the Trial of ORG 10172 in Acute Stroke Treatment criteria. The types of HT included any intracerebral hemorrhage (ICH), parenchymal hematoma, and symptomatic ICH within 24 hours after endovascular treatment. The association between stroke subtype and HT was analyzed using a logistic regression model. Mediation analysis was done to assess how much of the effect of stroke subtype on HT was mediated through the identified mediators. Results: Stroke subtype (cardioembolism versus large artery atherosclerosis) was associated with increased risk of any ICH (29.8% versus 16.5%; odds ratio, 2.03 [95% CI, 1.22–3.36]), parenchymal hematoma (14.3% versus 5.4%; odds ratio, 2.90 [95% CI, 1.38–6.13] ), and symptomatic ICH (9.9% versus 4.7%; odds ratio, 2.59 [95% CI, 1.09–6.16]) after adjustment for potential confounders. The more thrombectomy passes in cardioembolism patients had a significant mediation effect on the association of stroke subtype with increased risk of HT (any ICH, 15.9%; parenchymal hematoma, 13.4%; symptomatic ICH, 14.2%, respectively). Conclusions: Stroke subtype is an independent risk factor for HT within 24 hours following endovascular treatment among acute large vessel occlusion patients. Mediation analyses propose that stroke subtype contributes to HT partly through thrombectomy pass, suggesting a possible pathomechanistic link.

    Abstract: The benefit of endovascular treatment (EVT) for large vessel occlusion in clinical practice in developing countries like China needs to be confirmed. The aim of the study was to determine whether the benefit of EVT for acute ischemic stroke in randomized trials could be generalized to clinical practice in Chinese population. Methods: We conducted a prospective registry of EVT at 111 centers in China. Patients with acute ischemic stroke caused by imaging-confirmed intracranial large vessel occlusion and receiving EVT were included. The primary outcome was functional independence at 90 days defined as a modified Rankin Scale score of 0 to 2. Outcomes of specific subgroups in the anterior circulation were reported and logistic regression was performed to predict the primary outcome. Results: Among the 1793 enrolled patients, 1396 (77.9%) had anterior circulation large vessel occlusion (median age, 66 [56–73] years) and 397 (22.1%) had posterior circulation large vessel occlusion (median age, 64 [55–72] years). Functional independence at 90 days was reached in 45% and 44% in anterior and posterior circulation groups, respectively. For anterior circulation population, underlying intracranial atherosclerotic disease was identified in 29% of patients, with higher functional independence at 90 days (52% versus 44%; P =0.0122) than patients without intracranial atherosclerotic disease. In the anterior circulation population, after adjusting for baseline characteristics, procedure details, and early outcomes, the independent predictors for functional independence at 90 days were age 〈 66 years (odds ratio [OR], 1.733 [95% CI, 1.213–2.476] ), time from onset to puncture 〉 6 hours (OR, 1.536 [95% CI, 1.065–2.216]), local anesthesia (OR, 2.194 [95% CI, 1.325–3.633] ), final modified Thrombolysis in Cerebral Infarction 2b/3 (OR, 2.052 [95% CI, 1.085–3.878]), puncture-to-reperfusion time ≤1.5 hours (OR, 1.628 [95% CI, 1.098–2.413] ), and National Institutes of Health Stroke Scale score 24 hours after the procedure 〈 11 (OR, 9.126 [95% CI, 6.222–13.385]). Conclusions: Despite distinct characteristics in the Chinese population, favorable outcome of EVT can be achieved in clinical practice in China.

    Abstract: This study aimed to compare the efficacy of percutaneous drainage (PCD) versus peritoneal lavage (PL) for the treatment for severe acute pancreatitis patients with pancreatic ascites (PAs). Methods Severe acute pancreatitis patients with PAs were randomly assigned within 3 days of onset of symptoms to receive either PL or PCD. The primary end point was a composite of mortality or major complications during hospitalization and within 1 month of discharge. Per-protocol analyses were performed. Results Between September 2011 and June 2014, 86 patients were randomly assigned to intervention with PL or PCD. Ultimately, 41 patients in the PCD group and 39 patients in the PL group completed the study. The primary end point occurred in 15 (36.6%) of 41 patients in the PCD group and in 17 (43.6%) of 39 patients in the PL group (risk ratio, 0.84; 95% confidence interval, 0.49–1.44; P = 0.27). Mortality or major complications did not differ between the groups. Percutaneous drainage reduced intra-abdominal hypertension; however, PL reduced the incidence of deep venous thrombosis and pancreatic encephalopathy and was associated with a reduced need for intervention. Conclusions In our study, the PCD was not superior to the PL in reducing mortality or major complications in severe acute pancreatitis patients with PAs.
