While single-modality deep neural networks (DNNs) have shown promising performance for detecting cardiac abnormalities, the potential benefits of using DNNs for multimodality risk assessment in patients with IHD have not been reported. The purpose of this study was to investigate the effectiveness of multimodality risk assessment in patients with IHD using a DNN that utilizes 12-lead electrocardiograms (ECGs) and chest X-rays (CXRs), with the prediction of major adverse cardiovascular events (MACEs) being of particular concern.DNN models were applied to detection of left ventricular systolic dysfunction (LVSD) on ECGs and identification of cardiomegaly findings on CXRs. A total of 2107 patients who underwent elective percutaneous coronary intervention were categorized into 4 groups according to the models' outputs: Dual-modality high-risk (n = 105), ECG high-risk (n = 181), CXR high-risk (n = 392), and No-risk (n = 1,429).A total of 342 MACEs were observed. The incidence of a MACE was the highest in the Dual-modality high-risk group (P < 0.001). Multivariate Cox hazards analysis for predicting MACE revealed that the Dual-modality high-risk group had a significantly higher risk of MACE than the No-risk group (hazard ratio (HR): 2.370, P < 0.001), the ECG high-risk group (HR: 1.906, P = 0.010), and the CXR high-risk group (HR: 1.624, P = 0.018), after controlling for confounding factors.The results suggest the usefulness of multimodality risk assessment using DNN models applied to 12-lead ECG and CXR data from patients with IHD.\u0000","PeriodicalId":13711,"journal":{"name":"International heart journal","volume":"7 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139665401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In vivo, inflammatory cytokine (including TNF-α, IL-1β, IL-6, and TGF-β, the level of SOD) expression, superoxide dismutase and hydrogen peroxide levels, and p-IκBα and p65 expressions were detected. In vitro, pulmonary artery smooth muscle cell proliferation and migration, ROS production, and hypoxia-inducible factor-1 expression were also studied.Results: Hydroxycitric acid tripotassium hydrate decreased right ventricular systolic pressure and reduced right ventricular fibrosis and pulmonary vascular remodeling in rats with two kinds of pulmonary hypertension. Moreover, the expression of both inflammatory and oxidative stress factors was effectively reduced, and the p65 signaling pathway was found to be inhibited in this study. Additionally, hydroxycitric acid tripotassium hydrate inhibited human pulmonary artery smooth cell proliferation and migration in vitro.Conclusions: This study shows that hydroxycitric acid tripotassium hydrate can alleviate pulmonary hypertension caused by hypoxia and monocycloline in rats, improve remodeling of the right ventricle and pulmonary artery, and inhibit pulmonary artery smooth muscle cell proliferation and migration. The protective effects may be achieved by regulating inflammation and oxidative stress through the p65 signaling pathway.","PeriodicalId":13711,"journal":{"name":"International heart journal","volume":"65 2","pages":"318-328"},"PeriodicalIF":1.5,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140331689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To silence FABP4 expression and NF-κB signaling in HUVECs, FABP4 inhibitor and NF-κB inhibitor were utilized. To assess cell survival rate and apoptosis, methyl thiazolyl tetrazolium assays and flow cytometry analysis were conducted. Genes related to cholesterol metabolism, including LOX-1, ABCA1, and ABCG1, were subjected to RT-qPCR and western blotting. Moreover, protein levels of apoptotic markers (Bcl-2 and Bax), PPARγ, the phosphorylated levels of NF-κB p65, and angiogenetic markers (ICAM1, VCAM1, and VEGF) were quantified via western blotting. Using an enzyme-linked immunosorbent assay, concentrations of inflammatory cytokines in HUVECs were measured.FABP4 expression was upregulated in LPS-stimulated HUVECs. The silencing of FABP4 lowered LOX-1 and p65 levels while upregulating ABCA1 and ABCG1 expression in the context of LPS. Furthermore, the inhibition of FABP4 or NF-κB signaling promoted the growth of HUVECs, upregulated Bcl-2 and PPARγ protein levels, and reduced Bax levels, angiogenetic markers, and inflammatory cytokines in the context of LPS. The combination of FABP4 inhibitor and NF-κB inhibitor treatment amplified the above-mentioned effects on cell growth, angiogenesis, and inflammation.Inhibition of FABP4 reduces LPS-induced HUVEC cell damage via the inactivation of NF-κB p65 and activation of PPARγ signaling.","PeriodicalId":13711,"journal":{"name":"International heart journal","volume":"65 6","pages":"1153-1160"},"PeriodicalIF":1.2,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142768380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated 1) the diagnostic value of the thoracic aortic calcification (TAC) score for detecting AAP and large complex AAP and 2) the prognostic significance of TAC in patients with chronic coronary syndrome (CCS). The predictors of AAPs with large (≥ 4 mm in thickness) and complex (ulcerated or protruded) morphologies were evaluated in 412 symptomatic patients with CCS who underwent coronary computed tomography angiography and simultaneous assessment of the aortic arch. Receiver operating curve analysis was performed to determine whether the TAC score can improve the diagnostic value of complex large AAP compared with clinical parameters. Multivariate logistic regression analyses revealed that the TAC score was an independent predictor of complex large AAP (odds ratio, 1.46; P = 0.0074). The area under the curve (AUC) for the base model comprising clinical parameters (age ≥ 70 years + current smoking status + systolic blood pressure) was 0.707 (P = 0.0177). The addition of a TAC score of ≥ 978 Agatston units (AUC, 0.744) significantly improved the AUC (AUC, 0.751, P < 0.001) for patients aged ≥ 70 years (AUC, 0.638). The multivariable Cox hazard model revealed that TAC of ≥ 432.4 (hazard ratio [HR], 4.312; P = 0.01) and large complex AAP are independently associated with the incidence of major adverse cardiovascular events (HR, 3.108; P = 0.011). This study demonstrated that TAC and AAP morphology serve as markers of major adverse cardiovascular events.
