Despite these associations, the interplay between TIMP4 and the Th17/Treg ratio remains poorly understood. Our research sought to elucidate the impact of TIMP4 on HF pathogenesis, with a particular emphasis on its influence on Th17 and Treg lymphocyte populations.</p><p><strong>Methods: </strong>Bioinformatics analysis of the GSE196656 dataset was conducted. An isoprenaline-induced Sprague-Dawley rat model of heart failure was used, with rats divided into groups: HF alone, HF with TIMP4 overexpression, and HF with TIMP4 knockdown. Heart failure in primary myocardial cell cultures was induced using Angiotensin II, and exosomes were collected from the culture medium. ELISA, western blot, TUNEL staining, qRT-PCR, RNA extraction analysis the impact of TIMP4 on heart failure. Additionally, purified naïve CD4+ T cells from rats were used in vitro to investigate TIMP4's influence on Th17 and Treg cell differentiation.</p><p><strong>Results: </strong>Analysis of the GSE196656 dataset revealed significant upregulation of TIMP4 in heart failure. Myocardial exosomal TIMP4 was significantly elevated in the heart failure model. In the experimental rat model, TIMP4 overexpression significantly reduced plasma levels of biomarkers related to heart injury as well as inflammation, enhanced indicators of heart function and suppressed cell death in the heart muscle. Furthermore, TIMP4 overexpression decreased IL-17 levels and the Th17 cell proportion while promoting Treg cell differentiation and increasing IL-10 levels. In vitro studies demonstrated that TIMP4 effectively inhibits the differentiation of Th17 cells and promotes the growth of Treg cells. These effects were observed to vary depending on the dosage.</p><p><strong>Conclusion: </strong>TIMP4 overexpression exerts a protective effect in heart failure by inhibiting myocardial injury, inflammation, and apoptosis, and by regulating immune cell balance. These findings imply that targeting TIMP4 could potentially serve as a therapeutic strategy for heart failure, as it has the ability to regulate immune responses and minimize damage to the myocardium.</p>","PeriodicalId":9391,"journal":{"name":"Cardiology","volume":" ","pages":"1-15"},"PeriodicalIF":1.9,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144149595","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}

The ratio of the pulse wave velocity (PWV) to left ventricular global longitudinal strain (GLS) has been established as a reliable noninvasive metric for assessing VAC.</p><p><strong>Aims: </strong>This study aimed to assess VAC noninvasively in heart failure (HF) using the estimated pulse wave velocity (ePWV) to GLS ratio, defined from speckle tracking imaging.</p><p><strong>Methods: </strong>According to the HF stages by the American Heart Association, 131 subjects were divided into four groups: group 1 (n = 36) at risk of developing HF and pre-HF (American College of Cardiology/American Heart Association stages A and B), group 2 (n = 35) having HF with preserved ejection fraction (HFpEF), group 3 (n = 35) having HF with reduced ejection fraction (HFrEF), and group 4 (n = 30) as controls. To determine the ePWV/GLS ratio, the ePWV was calculated based on the previously established formula using age and mean pressure, and the GLS was derived from speckle tracking echocardiography. The study evaluated the VAC in all groups and compared with the established metrics such as arterial elasticity (Ea) and ventricular end-systolic elasticity (Ees) ratios. The correlation between the ePWV/GLS ratio and other parameters obtained by echocardiography was also assessed.</p><p><strong>Results: </strong>Significant differences in the ePWV/GLS ratio were observed among the groups, and the severity of VAC impairment correlated with the HF stage. The lowest ePWV/GLS ratio was observed in the control and stage A-B group (0.530 ± 0.100 vs 0.640 ± 0.10), followed by the HFpEF group (0.992 ± 0.215), whereas the HFrEF group had the highest ratio (1.500 ± 0.369). The ePWV/GLS ratio showed a moderate correlation with the Ea/Ees ratio [r =0.753, (95% CI, 0.665-0.821), P <0.0001], but performed better in distinguishing HF subtypes. A threshold of 0.625 for the ePWV/GLS ratio was established by the ROC curve to detect the impaired VAC, with an AUROC of 0.923 and 95% CI of 0.876-0.969. In addition, the ePWV/GLS ratio was strongly associated with N-terminal pro-B-type natriuretic peptide (NT-proBNP) and moderately correlated with left ventricular mass index (LVMI), end-diastolic volume (EDV), left ventricular ejection fraction (LVEF), age, and E/e'.</p><p><strong>Conclusion: </strong>The ePWV/GLS ratio is an easily accessible parameter for evaluating VAC.

TMAO, a metabolite produced by gut microbiota acting on dietary precursors, is associated with various cardiovascular diseases. In AAA, TMAO is involved in multiple processes. It induces inflammation by promoting macrophage polarization and increasing inflammatory markers in vascular smooth muscle cells. It also participates in apoptosis and extracellular matrix remodeling. TMAO is closely associated with risk factors such as atherosclerosis, hypertension, and diabetes and affects their progression through multiple mechanisms, such as in atherosclerosis, where it promotes foam cell formation and endothelial cell damage. Intervention strategies for TMAO include dietary modification, gut microbiota regulation, and inhibition of key enzymes. Dietary modifications such as the Mediterranean diet can reduce TMAO levels, and probiotics and prebiotics have shown a potential to modulate gut microbiota to affect TMAO synthesis. However, these strategies have limitations and require further study.
