Abstract

Background: Fragmented QRS complex (fQRS), an easily evaluated noninvasive electrocardiographic parameter, is associated with worse outcomes in patients with several cardiovascular conditions. The presence of fQRS on ECG may be an indicator of myocardial damage in patients with coronary artery disease (CAD). In this article, we performed a meta-analysis in order to characterize the presence of fQRS on ECG in patients with CAD.Methods: We searched English-language randomized controlled trials involving fQRS on ECG in patients with CAD (n = 3279 patients, 12 trials). Two reviewers independently extracted data. Data on LVEF, LVESD, LVEDD, LVESV, LVEDV, total mortality, stroke, and MACE were collected. fQRS was performed a comparison with non-fQRS, calculating pooled relatives risk (RRs) and weighted mean difference (WMD), and associated 95% confidence intervals (CIs).Results: fQRS was associated with significant increased WMD of LVEDD (WMD, 2.26; 95%CI, 0.92 to 0.36, P = 0.0009), LVESD (WMD, 2.71; 95%CI, 1.23 to 4.19, P = 0.0003), LVEDV (WMD, 31.37; 95%CI, 24.82 to 37.92, P < 0.00001), and LVESV (WMD, 28.45; 95%CI, 22.92 to 33.98, P < 0.00001). As compared to non-fQRS, fQRS increased risk of total mortality (RR, 3.09; 95%CI, 1.76 to 5.44, P < 0.0001) and MACE (RR, 2.85; 95%CI, 1.98 to 4.09, P < 0.00001) in patients with CAD. However, a decreased trend was observed for LVEF (WMD, -3.59; 95%CI, -7.05 to -0.12, P = 0.04). For the incidence of stoke, there was no difference between fQRS and non-fQRS group.Conclusions: Our findings indicate that fQRS is a valuable factor to predict total mortality and MACE in patients with CAD.

Abstract

SnO 2 -based electron transport layers (ETLs) offer outstanding band alignment, excellent chemical and UV stability, high transmittance, high conductivity, and processability at low temperatures. However, unfortunately, the state-of-the-art SnO 2 colloid precursor suffered from agglomeration over time and structural defects such as dangling hydroxyl groups and oxygen vacancies, which deteriorate both the morphology and electronic quality of the resulting ETL. Especially, these trap states near the valence band can hinder charge extraction and transport of electrons to couple with non-radiative recombination loss. Here, we introduce a novel WO 3 @SnO 2 nanocomposite ETL, which is synthesized by in situ peptizations of WO 3 in commercial alkaline SnO 2 colloid nanocrystals. The hydrated (peptized) WO 3 forms H 2 WO 4 (WO 4 2-) to effectively stabilize the SnO 2 nanocrystals in the dispersion and bind to the defect sites. Intriguingly, the H 2 WO 4 converts back to the WO 3 phase to form nano-heterostructured composite with SnO 2 particles during the process of film fabrication, further promoting passivation and charge extraction. Through the novel method, we could achieve molecular level passivation of SnO 2 layer by WO 3 , and a power conversion efficiency of 23.6% for a 0.1 cm2 PSC device with ultra-high FF of 85.8% was demonstrated. Furthermore, a modified detailed balance model was used to verify the drastically lessened surface & bulk defect-induced recombination loss in WO 3 @SnO 2 based devices. Finally, the corresponding unencapsulated cell retained ~91% of its initial efficiency after 2000 h of damp exposure. This work provides a promising method to access the Shockley–Queisser limit of fill factor for single-junction PSC. [Display omitted] • A stable colloidal WO 4 2-/SnO 2 system is prepared by in situ peptizations of WO 3 in the alkaline SnO 2. • The WO 4 2- anions can heal the hydroxyl and oxygen vacancy defects sites. • Upon sintering, H 2 WO 4 dehydrate back to the WO 3 to form nano-heterostructure with SnO 2. • The optimized device delivers an efficiency of 23.6% and ultrahigh FF of 85.8%.
