    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: Edaravone dexborneol, comprised of 2 active ingredients, edaravone and (+)-borneol, has been developed as a novel neuroprotective agent with synergistic effects of antioxidant and anti-inflammatory in animal models. The present clinical trial aimed at testing the effects of edaravone dexborneol versus edaravone on 90-day functional outcome in patients with acute ischemic stroke (AIS). Methods: A multicenter, randomized, double-blind, comparative, phase III clinical trial was conducted at 48 hospitals in China between May 2015 and December 2016. Inclusion criteria included patients diagnosed as AIS, 35 to 80 years of age, National Institutes of Health Stroke Scale Score between 4 and 24, and within 48 hours of AIS onset. AIS patients were randomized in 1:1 ratio into 2 treatment arms: 14-day infusion of edaravone dexborneol or edaravone injection. The primary end point was the proportion of patients with modified Rankin Scale score ≤1 on day 90 after randomization. Results: One thousand one hundred sixty-five AIS patients were randomly allocated to the edaravone dexborneol group (n=585) or the edaravone group (n=580). The edaravone dexborneol group showed significantly higher proportion of patients experiencing good functional outcomes on day 90 after randomization, compared with the edaravone group (modified Rankin Scale score ≤1, 67.18% versus 58.97%; odds ratio, 1.42 [95% CI, 1.12–1.81]; P =0.004). The prespecified subgroup analyses indicated that a greater benefit was observed in female patients than their male counterparts (2.26, 1.49–3.43 versus 1.14, 0.85–1.52). Conclusions: When edaravone dexborneol versus edaravone was administered within 48 hours after AIS, 90-day good functional outcomes favored the edaravone dexborneol group, especially in female patients.

    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 dual-antiplatelet therapy with clopidogrel plus aspirin has been demonstrated to substantially decrease the risk of recurrent stroke among patients with minor stroke and transient ischemic attack. We aimed to determine whether the efficacy of clopidogrel-aspirin therapy among patients with minor stroke / transient ischemic attack was influenced by the stratification of CYP2C19 genotype and body mass index (BMI). Methods— CYP2C19 loss-of-function allele (LoFA) carriers were defined as patients with either LoFA of *2 or *3. Low/normal weight and overweight/obesity was defined as BMI 〈 25 and ≥25 kg/m 2 , respectively. Primary outcome was defined as stroke recurrence at 3 months. Results— In a total of 2933 patients, there were 1726 (58.8%) LoFA carriers and 1275 (43.5%) patients with overweight/obesity (BMI ≥25 kg/m 2 ). Stratified analyses by LoFA carrying status and BMI, hazard ratios (hazard ratios 95% CIs) of the clopidogrel-aspirin therapy for stroke recurrence were 0.90 (0.60–1.36), 0.87 (0.56–1.35), 0.65 (0.39–1.09), and 0.40 (0.22–0.71) among subgroups of LoFA carriers with overweight/obesity, LoFA carriers with low/normal weight, LoFA noncarriers with overweight/obesity, and LoFA noncarriers with low/normal weight, respectively, with P =0.049 for interaction. Conclusions— Efficacy of clopidogrel-aspirin therapy in reducing the risk of stroke recurrence is not present in CYP2C19 LoFA noncarriers with overweight/obesity. Our study suggests that BMI significantly influences the correlation between CYP2C19 genotype and efficacy of clopidogrel-aspirin therapy.

    Abstract: Infection occurs commonly in patients with acute ischemic stroke. We aimed to investigate the association of infection with short- and long-term risk of recurrent stroke in patients with ischemic stroke. Methods: Data were derived from ischemic stroke patients in 2 stroke registries: the CSCA (Chinese Stroke Center Alliance) program recorded medical data during hospitalization, and the CNSR-III (Third China National Stroke Registry) recorded the medical data during hospitalization and finished 1-year follow-up. Associations of infection (pneumonia or urinary tract infection) during hospitalization with recurrent stroke in short (during hospitalization) and long term (since 30 days to 1 year after stroke onset) were analyzed. Short-term outcomes were analyzed with logistic models and long-term outcomes with Cox models. Results: In the CSCA (n=789 596), the incidence of infection during hospitalization reached 9.6%. Patients with infection had a higher risk of stroke recurrence during hospitalization compared with patients without infection (10.4% versus 5.2%; adjusted odds ratio, 1.70 [95% CI, 1.65–1.75]; P 〈 0.0001). In the CNSR-III (n=13 549), the incidence of infection during hospitalization was 6.5%. Infection during hospitalization was significantly associated with short-term risk of recurrent stroke (7.4% versus 3.9%; adjusted odds ratio, 1.40 [95% CI, 1.05–1.86]; P =0.02) but not with long-term risk of recurrent stroke (7.2% versus 5.2%; adjusted hazard ratio, 1.16 [95% CI, 0.88–1.52]; P =0.30). Conclusions: Infection was an independent risk factor for high risk of early stroke recurrence during hospitalization, but we have not found its sustained effect on long-term recurrent risk in patients with acute ischemic stroke.

    Abstract: We assessed prospectively whether nonalcoholic fatty liver disease (NAFLD) and its severity predict future ischemic stroke (IS) events in a community-based cohort. Methods: From the Kailuan study, participants free of history of stroke, cancer, or myocardial infarction were enrolled after excluding alcohol abuse and other liver diseases. NAFLD was evaluated through ultrasonography. Participants with NAFLD were further stratified into mild, moderate, and severe groups. The outcome was the first occurrence of IS. The secondary outcomes included myocardial infarction and combined vascular events. We used Cox proportional hazards models to estimate hazard ratios and 95% CIs of incident IS according to presence and severity of NAFLD, adjusting for age, sex, physical activity, body mass index, smoker, history of hypertension, diabetes, hypercholesterolemia, lipid-lowering medication, HDL (high-density lipoprotein), triglyceride, hsCRP (high-sensitivity C-reactive protein), and fasting blood glucose. Results: During a median of 10.34 years of follow-up, we documented 3490 incident stroke cases among 79 905 participants. NAFLD was found in 24 874 (31.18%) participants. Relative to participants without NAFLD at the baseline, those with NAFLD had a 16% higher risk (95% CI, 1.07–1.26) of developing ischemic stroke, after adjusted for confounding variables. The hazard ratios for patients with mild, moderate, and severe NAFLD were 1.15 (95% CI, 1.05–1.25), 1.19 (95% CI, 1.06–1.34), and 1.21 (95% CI, 1.08–1.50), respectively. Conclusions: The severity of NAFLD is associated with a higher risk of future ischemic stroke events.

    Abstract: It is still unclear whether the residual cholesterol and inflammatory risk in the acute phase is associated with prognosis of stroke. We aimed to investigate the proportion and relative contribution of residual cholesterol and inflammatory risk, determined by baseline low-density lipoprotein cholesterol (LDL-C) and high-sensitivity C-reactive protein (hsCRP) levels, to the risk of recurrent stroke and poor functional outcome at 1 year. Methods: In this prospective multicenter cohort study, 10 499 consecutive acute ischemic stroke and transient ischemic attack patients with levels of LDL-C and hsCRP were enrolled. Patients were divided into 4 groups: residual cholesterol risk only (LDL-C ≥2.6 mmol/L and hsCRP 〈 3 mg/L), residual inflammatory risk (RIR) only (LDL-C 〈 2.6 mmol/L and hsCRP ≥3 mg/L), both risk (LDL-C ≥2.6 mmol/L and hsCRP ≥3 mg/L), and neither risk (LDL-C 〈 2.6 mmol/L and hsCRP 〈 3 mg/L). The primary outcomes consisted of stroke recurrence and a modified Rankin Scale score of 2 to 6 within 1 year. Results: The relative proportions of patients with RIR only, residual cholesterol risk only, both risk, and neither were 21.3%, 23.7%, 14.4%, and 40.6%, respectively. RIR only was independently associated with recurrent stroke (adjusted hazard ratio, 1.18 [95% CI, 1.00–1.40]; P =0.05). The association was slightly attenuated after further adjusting for usage of antiplatelet agent and statin during 1-year follow-up in addition to the traditional risk factors (hazard ratio, 1.31 [95% CI, 0.99–1.76]; P =0.07). When applying the LDL-C cutoff value of 1.8 mmol/L in the sensitivity analyses, such association in large-artery atherosclerosis subtype was more significant (adjusted hazard ratio, 1.69 [95% CI, 1.06–2.67]; P =0.03). Patients with RIR only also had increased risk of poor functional outcome (adjusted odds ratio, 1.43 [95% CI, 1.24–1.64]; P 〈 0.0001). Conclusions: In the patients with acute ischemic stroke or transient ischemic attack, RIR only could be predictive for recurrent stroke, especially for those with large-artery atherosclerosis, and poor functional outcome.

    Abstract: Trimethylamine N-oxide (TMAO) has been recognized as a risk factor for cardiovascular disease. However, the role of TMAO in ischemic stroke remains unclear. As we know, ischemic stroke is a heterogeneous disease with variable pathogenesis. Hence, we aimed to investigate the association between TMAO and stroke recurrence according to etiology subtypes. Methods: A total of 10 756 ischemic stroke/transient ischemic attack patients from the Third China National Stroke Registry were enrolled, and 1-year follow-up data for stroke recurrence were analyzed. TOAST (Trial of ORG 10172 in Acute Stroke Treatment) criteria was used to classify the etiology subtypes. Plasma TMAO levels were quantified by liquid chromatography–mass spectrometry. The association between TMAO and stroke outcomes was analyzed using Cox regression models. We also conducted a meta-analysis on the association of TMAO levels and stroke risk. Results: Elevated TMAO level was independently associated with the risk of stroke recurrence (Q4 versus Q1: adjusted hazard ratio, 1.37 [95% CI, 1.15–1.64]) in multivariate Cox regression model. After stratification by TOAST subtypes, there was a significant association between TMAO and stroke recurrence in small artery occlusion subtype (adjusted hazard ratio, 1.43 [95% CI, 1.03–2.00] ) but not in the others subtype (large-artery atherosclerosis, 1.19 [0.95–1.48]; cardioembolism, 1.54 [0.95–2.48] ; others, 1.19 [0.98–1.44]). The meta-analysis reported on stroke recurrence for the highest versus lowest TMAO levels with a pooled hazard ratio of 1.66 (95% CI, 0.91–3.01) and similarly found an increased risk of stroke recurrence. Conclusions: Elevated TMAO level is associated with increased risk of stroke recurrence in patients with small artery occlusion subtype, but this association seems to be attenuated in large-artery atherosclerosis, cardioembolism, and others subtypes.

    Abstract: Lp(a) (lipoprotein(a)) contributes to cardiovascular disease mainly through proatherogenic and proinflammatory effects. Here, we aimed to evaluate whether a residual stroke risk of Lp(a) would remain when the LDL-C (low-density lipoprotein cholesterol) and inflammatory levels are maintained low. Methods: This prospective cohort study included 9899 patients with ischemic stroke or transient ischemic attack from the Third China National Stroke Registry who had measurements of plasma Lp(a) and were followed up for 1 year. Cutoffs were set at the 50 mg/dL for Lp(a). LDL-C was corrected for Lp(a)-derived cholesterol (LDL-Cc [LDL-C corrected]) and cutoffs were set at 55 and 70 mg/dL.The threshold values of IL-6 (interleukin 6) and hsCRP (high-sensitive C-reactive protein) were the median 2.65 ng/L and 2 mg/L. Multivariable-adjusted hazard ratio (HR) were calculated using Cox regression models for each category to investigate the associations of Lp(a) with stroke recurrence within 1 year. Results: Among all patients, those with Lp(a) ≥50 mg/dL were at higher stroke recurrence risk than those with Lp(a) 〈 50 mg/dL (11.5% versus 9.4%; adjusted HR, 1.20 [95% CI, 1.02–1.42]). However, the risk associated with elevated Lp(a) was attenuated in patients with LDL-Cc 〈 55 mg/dL (high Lp(a) versus low Lp(a): 8.9% versus 9.0%; adjusted HR, 0.92 [95% CI, 0.65–1.30]) or IL-6 〈 2.65 ng/L (9.0% versus 7.8%; adjusted HR, 1.14 [95% CI, 0.87–1.49]). Notably, in the group with both low LDL-Cc and inflammation levels, the rate of patients with high Lp(a) did not significantly different from the rate of patients with low Lp(a; LDL-Cc 〈 55 mg/dL and IL-6 〈 2.65 ng/L: 6.2% versus 7.1%; adjusted HR, 0.86 [95% CI, 0.46–1.62]; LDL-Cc 〈 55 mg/dL and hsCRP 〈 2 mg/L: 7.7% versus 7.6%; adjusted HR, 0.97 [95% CI, 0.57–1.66]). However, there was no interaction between the LDL-Cc, IL-6, hsCRP, and Lp(a) levels on stroke recurrence risk. Conclusions: Increased Lp(a) was significantly associated with stroke recurrence risk in patients with ischemic stroke/transient ischemic attack. However, at low LDL-Cc or IL-6 levels, the elevated Lp(a) -associated stroke recurrence risk was attenuated in a secondary prevention setting.
