Objective The predictive value of N-terminal pro-brain natriuretic peptide(NT-proBNP) in patients with stable coronary artery disease(SCAD) in the drug-eluting stent era is not yet clear. We aimed to evaluate the prognostic value of NT-proBNP in SCAD patients after percutaneous coronary intervention(PCI). Methods We examined 4,293 consecutive SCAD patients who underwent PCI between January 2013 and December 2013 in Fuwai Hospital, China. The primary endpoint was all-cause death. NT-proBNP levels were measured before PCI using Elisa kits(Biomedica, Austria). The indication for PCI was based on the degree of coronary stenosis and evidence of ischemia. Results Among 3,187 SCAD patients with NT-proBNP data, after a 2-year follow-up, NT-proBNP levels were predictive for all-cause death in the SCAD population [area under the receiver operating characteristic curve, 0.768; 95% confidence interval(CI), 0.687-0.849; P < 0.001]. At the optimum cutoff point of 732 pg/mL, the sensitivity and specificity of death was 75.0% and 72.3%, respectively. In a multivariable Cox regression model, the death hazard ratio was 6.43(95% CI, 2.99-13.82; P < 0.001) for patients with NT-proBNP levels ≥ 732 pg/mL, compared with < 732 pg/mL. Conclusion NT-proBNP is a strong predictor of 2-year death with SCAD after PCI in the drug-eluting stent era.

Objective To analyze factors associated with unplanned revascularization(UR) risk in patients with coronary artery disease(CAD) who underwent percutaneous coronary intervention(PCI).Methods A total of 10,640 cases with CAD who underwent PCI were analyzed. Multivariate COX regressions and competing risk regressions were *** The patients who underwent UR following PCI in 30 days, 1, and 2 years accounted for 0.3%,6.5%, and 8.7%, respectively. After multivariate adjustment, the number of target lesions [hazard ratio(HR) = 2.320;95% confidence interval(CI): 1.643–3.277;P < 0.001], time of procedure(HR = 1.006;95%CI: 1.001–1.010;P = 0.014), body mass index(HR = 1.104;95% CI: 1.006–1.210;P = 0.036), incomplete revascularization(ICR)(HR = 2.476;95% CI: 1.030–5.952;P = 0.043), and age(HR = 1.037;95% CI:1.000–1.075;P = 0.048) were determined as independent risk factors of 30-day UR. Factors, including low-molecular-weight heparin or fondaparinux(HR = 0.618;95% CI: 0.531–0.719;P < 0.001), secondgeneration durable polymer drug-eluting stent(HR = 0.713;95% CI: 0.624–0.814;P < 0.001), left anterior descending artery involvement(HR = 0.654;95% CI: 0.530–0.807;P < 0.001), and age(HR = 0.992;95%CI: 0.985–0.998;P = 0.014), were independently associated with decreased two-year UR risk. While,Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery score(HR =1.024;95% CI: 1.014–1.033;P < 0.001) and ICR(HR = 1.549;95% CI: 1.290–1.860;P < 0.001) were negatively associated with two-year UR *** Specific factors were positively or negatively associated with short-and medium-long-term UR following PCI.

The growth of dendrites and the side reactions occurring at the Zn anode pose significant challenges to the commercialization of aqueous Zn-ion batteries(AZIBs). These challenges arise from the inherent conflict between mass transfer and electrochemical kinetics. In this study, we propose the use of a multifunctional electrolyte additive based on the xylose(Xylo) molecule to address these issues by modulating the solvation structure and electrode/electrolyte interface, thereby stabilizing the Zn anode. The introduction of the additive alters the solvation structure, creating steric hindrance that impedes charge transfer and then reduces electrochemical kinetics. Furthermore, in-situ analyses demonstrate that the reconstructed electrode/electrolyte interface facilitates stable and rapid Zn^(2+)ion migration and suppresses corrosion and hydrogen evolution reactions. As a result, symmetric cells incorporating the Xylo additive exhibit significantly enhanced reversibility during the Zn plating/stripping process, with an impressively long lifespan of up to 1986 h, compared to cells using pure ZnSO4electrolyte. When combined with a polyaniline cathode, the full cells demonstrate improved capacity and long-term cyclic stability. This work offers an effective direction for improving the stability of Zn anode via electrolyte design, as well as highperformance AZIBs.

Background: The patterns of nonadherence to antiplatelet regimen in stented patients(PARIS) thrombotic risk score are a novel score for predicting the risk of coronary thrombotic events(CTEs) after percutaneous coronary intervention(PCI) with drug?eluting ***, the prognostic value of this score has not been fully evaluated in non?Euro?American PCI ***: We performed a prospective, observational study of 10,724 patients who underwent PCI in Fuwai hospital, China and evaluated the PARIS thrombotic risk score’s predictive value of CTEs in the PCI population. The area under the receiver operating characteristic curve(AUROC) was used to assess the predictive value of the PARIS score for ***: Among 9782 patients without in?hospital events, a total of 95 CTEs occurred during the 2?year follow?up. The PARIS score was significantly higher in patients with CTEs(3.38 ± 2.04) compared with patients without events(2.53 ± 1.70, P < 0.001).According to the risk stratification of the PARIS thrombotic score, the risk of CTEs in the high?risk group was 3.14 times higher than that in the low?risk group(hazard ratio [HR], 3.14; 95% confidence interval [CI], 1.92–5.13; P < 0.001). However, the risk of CTEs in the intermediate?risk and low?risk groups was not significant(HR, 1.39; 95% CI, [0.86–2.24]; P = 0.184). The PARIS score showed prognostic value in evaluating CTEs in the overall population(AUROC, 0.621; 95% CI, 0.561–0.681), the acute coronary syndrome(ACS) population(AUROC, 0.617; 95% CI, 0.534–0.700; P = 0.003), and the non?ACS population(AUROC, 0.647; 95%CI, 0.558–0.736; P = 0.001).Conclusions: In a real?world Chinese population, the PARIS thrombotic risk score shows a modest prognostic value for CTEs in patients after PCI. This score also has a predictive value for CTEs in the ACS and non?ACS subgroup populations.
