Abstract
Heart failure (HF) is a complex clinical syndrome with impaired ventricular ability due to structural or functional cardiac disorders. A traditional Chinese formula named Xinshubao tablet (XSB) is reported to protect cardiomyocytes and decrease the risk of HF clinically; however, the underlying mechanism of XSB on decreasing HF risk is not elucidated yet. Therefore, our study aimed to investigate the therapeutic efficacy and underlying mechanism of XSB by using HF model rats and H9c2 cells with oxygen glucose deprivation. Echocardiographic and pathological features of animal experiment showed that XSB treatment effectively improved cardiac function and ameliorated myocardial injury after 4 weeks of treatment. Cellular experiments indicated that XSB pretreatment significantly inhibited apoptosis and increased mitochondrial energy metabolism. Furthermore, in vivo and in vitro experiments both demonstrated that XSB suppressed oxidative stress and inflammatory response. Our results further revealed that the potential protective mechanism of XSB was closely associated with the DCN/PPARα/PGC-1α/P300 signaling pathway. Our findings provide novel mechanistic insights for HF treatment and a pharmacological basis for the therapeutic application of XSB against cardiovascular disorders.

Abstract
PURPOSE The normal healthy valve is devoid of inflammatory cells, however background of aortic stenosis (AS) may include inflammatory processes. Moreover, the link between hyperparathyroidism and heart failure is postulated. Simple whole blood analysis with indices is a beneficial tool in cardiovascular diseases' assessment. The purpose of the study was to evaluate correlation between parathyroid hormone (PTH) and simple blood parameters in severe AS. MATERIAL AND METHODS The study included 62 patients with severe AS. Patients with inflammatory or autoimmune co-morbidities were excluded. Blood samples were collected, and clinical and demographic data were analyzed. RESULTS The final study group comprised 55 patients (31 females, 56.4%; mean age 77.13 (SD 6.76)). In 23 patients (41.8%), PTH concentration was markedly increased. The study group was divided into two subgroups according to the PTH concentration. Patients from both groups did not differ significantly in terms of age and co-morbidities. PTH concentration correlated positively with monocyte-lymphocyte ratio (MLR) (p = 0.008, Spearman rho 0.356) and platelet-lymphocyte ratio (PLR) (p = 0.047, Spearman rho 0.269), creatinine level (p = 0.001, Spearman rho 0.425) and glomerular filtration rate (GFR-MDRD) (p = 0.009, Spearman rho -0.349). The multivariable logistic regression with backward analysis revealed MLR (p = 0.029) and GFR (p = 0.028) as independent significant predictors of abnormal PTH values. The receiver operator characteristics (ROC) curve was performed for the model of MLR and GFR-MDRD (AUC = 0.777), yielding the sensitivity of 60.9% and specificity of 90.6%. CONCLUSIONS PTH concentration correlates with monocyte-to-lymphocyte and platelet-to-lymphocyte ratios in calcified AS.

Soluble ST2 levels are related to replacement myocardial fibrosis in severe aortic stenosis. REVISTA ESPANOLA DE CARDIOLOGIA (ENGLISH ED.) 2023; 76:679-689.

Abstract
INTRODUCTION AND OBJECTIVES Patients with aortic stenosis (AS) exhibit left ventricular (LV) remodeling and replacement myocardial fibrosis (RMF). Whether sST2 is associated with RMF measured by cardiac magnetic resonance and with sex remains unknown. METHODS We recruited 79 consecutive patients (73.0 [68.0-78.0] years; 61% men) with severe isolated AS underdoing valve replacement. RMF was identified and quantified by late gadolinium enhancement (LGE). Serum sST2 levels were determined. RESULTS RMF was associated with higher circulating sST2 levels, LV hypertrophy and dilation, and lower LV ejection fraction. All patients with LV dysfunction had RMF. Circulating levels of sST2 ≥ 28.8 ng/mL were associated with RMF and greater LV hypertrophy. LGE mass was correlated with LV remodeling and sST2. Of note, sST2 levels were also associated with the RMF pattern, being higher in midwall than in subendocardial fibrosis. Multivariate analyses showed that only LV ejection fraction and sST2 levels were associated with RMF. Moreover, men had higher levels of sST2 and RMF. RMF was associated with higher LV dilation and hypertrophy only in men and was correlated with LGE mass. CONCLUSIONS SST2 was an independent factor for RMF in patients with severe isolated AS. The presence of RMF was predicted by sST2 ≥ 28.2 ng/mL, and was associated with greater LV hypertrophy. sST2 expression and clinical associations may be sex-specific.

Abstract
ST2 is a member of interleukin 1 receptor family with soluble sST2 and transmembrane ST2L isoforms. The ligand of ST2 is IL-33, which determines the activation of numerous intracytoplasmic mediators following the binding with ST2L and IL-1RAcP, leading to nuclear signal and cardiovascular effect. Differently, sST2 is released in the blood and works as a decoy receptor, binding IL-33 and blocking IL-33/ST2L interaction. sST2 is mainly involved in maintaining homeostasis and/or alterations of different tissues, as counterbalance/activation of IL-33/ST2L axis is typically involved in the development of fibrosis, tissue damage, inflammation and remodeling. sST2 has been described in different clinical reports as a fundamental prognostic marker in patients with cardiovascular disease, as well as marker for the treatment monitoring of patients with heart failure; however, further studies are needed to better elucidate its role. In this review we reported the current knowledge about its role in coronary artery disease, heart failure, heart transplantation, heart valve disease, pulmonary arterial hypertension, and cardiovascular interventions.

Abstract
Allergic asthma is an inflammatory disorder of the bronchi, and as a major health problem, more than 350 million people suffer from asthma in the world. Many cardiovascular disorders resulted in the impairment of the heart's power to pump blood that leads to the HF. More than 25 million people worldwide live with HF. Accordingly, identifying the biomarkers to predict the onset of future asthma and HF is necessary. IL-33 is an inflammatory cytokine that has the main role in pathophysiology of asthma and HF. Also, in IL-33 receptor, the ST2 is involved in cardiac fibrosis and remodelling in HF and pathogenesis of allergic asthma. Increased sST2 in allergic asthma helps to control inflammation during asthma, but increased sST2 in HF is a predictable biomarker to present risk factor of HF during the time of the patients.

Abstract
Natriuretic peptides have been at the forefront of biomarker use in heart disease and have been universally recommended as the ideal biomarker in the setting of heart failure. Soluble ST2 is one such biomarker which has found value as a prognostic marker and can be used individually or along with natriuretic peptides in order to prognosticate patients with heart failure. Leading cardiovascular organisations have recognised this biomarker, though its role as a diagnostic marker is yet to be determined. We aim to investigate the role of sST2 in heart failure in the existing literature.

How Do Cardiovascular Biomarkers Behave in Patients with Severe Aortic Valve Stenosis with and without Echocardiographically Proven Pulmonary Hypertension?—A Retrospective Study of Biomarker Trends before and after Transcatheter Aortic Valve Replacement. APPLIED SCIENCES-BASEL 2022.

Abstract
Background: Since right heart catheterization is rarely performed in patients with severe aortic valve stenosis (AS), echocardiography is currently the tool of choice to determine the presence or absence of pulmonary hypertension (PH). The systolic pulmonary artery pressure (sPAP) has established itself as a reliable measurement value for this purpose. The aim of our study was to evaluate the behavior of plasma-level concentrations of novel cardiovascular biomarkers (sST2, GDF-15, H-FABP, IGF-BP2, and suPAR) in patients with severe AS and an sPAP < 40 mmHg in comparison to patients with an sPAP ≥ 40 mmHg before transcatheter aortic valve replacement (TAVR) and after TAVR (24 h, 96 h, 3 months, and 12 months). Methods: We retrospectively separated 85 patients with echocardiographic evidence of severe AS before TAVR procedure into two groups based on sPAP level. An sPAP of 40 mmHg was considered the cut-off value, with the absence of PH defined by an sPAP < 40 mmH (n = 32) and the presence of PH defined by an sPAP ≥ 40 mmHg (n = 53). Blood samples were drawn from each patient one day before TAVR and 24 h, 96 h, 3 months, and 12 months after TAVR. Plasma concentrations of the cardiovascular biomarkers sST2, GDF-15, H-FABP, IGF-BP2, and suPAR were determined and analyzed with univariate and multivariate binary logistic regression and AUROC curves. Results: Patients with severe AS and an sPAP ≥ 40 mmHg had significantly higher plasma concentrations of H-FABP (baseline: p = 0.022; 24 h: p = 0.012; 96 h: p = 0.037; 3 months: p = 0.006; 12 months: p = 0.030) and IGF-BP2 (baseline: p = 0.029; 24 h: p = 0.012; 96 h: p = 0.001; 3 months: p = 0.015; 12 months: p = 0.022) before and continuously up to 12 months after TAVR than did patients with an sPAP < 40 mmHg sST2, with the exception of the 12-month follow-up. We also consistently found significantly higher plasma concentrations in the sPAP ≥ 40 mmHg group (baseline: p = 0.007; 24 h: p = 0.006; 96 h: p = 0.014; 3 months: p ≤ 0.001; 12 months: p = 0.092), whereas suPAR had significantly elevated values at baseline and after 24 h in patients with echocardiographic evidence of PH and significantly decreased values after 3 months (baseline: p = 0.003; 24 h p = 0.041; 96 h: p = 0.127; 3 months: p = 0.006; 12 months: p = 0.477). Plasma concentrations of GDF-15 were only significantly different after 24 h (baseline: p = 0.075; 24 h: p = 0.016; 96 h: p = 0.101; 3 months: p = 0.244; 12 months: p = 0.090). In a multivariate binary logistic regression, atrial fibrillation, tricuspid annular plane systolic excursion (TAPSE), and sST2 at baseline were found to have a significant p-value < 0.050. Conclusion: In this descriptive study, sST2, H-FABP, and IGF-BP2 emerged as the cardiovascular biomarkers with the greatest potential with respect to echocardiographically PH detection in long-term follow-up after TAVR, as patients with an sPAP ≥ 40 mmHg had significantly continuously higher plasma biomarker concentrations than the corresponding cohort did, with an sPAP < 40 mmHg.

Abstract
Patients with severe aortic valve stenosis and concomitant pulmonary hypertension show a significantly reduced survival prognosis. Right heart catheterization as a preoperative diagnostic tool to determine pulmonary hypertension has been largely abandoned in recent years in favor of echocardiographic criteria. Clinically, determination of echocardiographically estimated systolic pulmonary artery pressure falls far short of invasive right heart catheterization data in terms of accuracy. The aim of the present systematic review was to highlight noninvasive possibilities for the detection of pulmonary hypertension in patients with severe aortic valve stenosis, with a special focus on cardiovascular biomarkers. A total of 525 publications regarding echocardiography, cardiovascular imaging and biomarkers related to severe aortic valve stenosis and pulmonary hypertension were analyzed in a systematic database analysis using PubMed Central®. Finally, 39 publications were included in the following review. It was shown that the current scientific data situation, especially regarding cardiovascular biomarkers as non-invasive diagnostic tools for the determination of pulmonary hypertension in severe aortic valve stenosis patients, is poor. Thus, there is a great scientific potential to combine different biomarkers (biomarker scores) in a non-invasive way to determine the presence or absence of PH.

Circulating Soluble ST2 Predicts All-Cause Mortality in Severe Heart Failure Patients with an Implantable Cardioverter Defibrillator. Cardiol Res Pract 2020; 2020:4375651. [PMID: 33282418 PMCID: PMC7685860 DOI: 10.1155/2020/4375651] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/25/2020] [Revised: 07/24/2020] [Accepted: 10/22/2020] [Indexed: 11/25/2022] Open
Abstract
Background Heart failure (HF) is the terminal stage of all cardiovascular events. Although implantable cardioverter defibrillator (ICD) therapies have reduced mortality among the high-risk HF population, it is necessary to determine whether certain factors can predict mortality even after cardiac device implantation. Growth stimulation expressed gene 2 (ST2) is an emerging biomarker for HF patient stratification in different clinical settings. Aims This study aimed to investigate the relationship between baseline soluble ST2 (sST2) levels in serum and the clinical outcomes of high-risk HF patients with device implantation. Methods Between January 2017 and August 2018, we prospectively recruited consecutive patients implanted with an ICD for heart failure, with LVEF ≤35% as recommended, and analyzed the basic characteristics, baseline serum sST2, and NT-proBNP levels, with at least 1-year follow-up. All-cause mortality was the primary endpoint. Results During a 643-day follow-up, all-cause mortality occurred in 16 of 150 patients (10.67%). Incidence of all-cause mortality increased significantly in patients with sST2 levels above 34.98846 ng/ml (16.00% vs. 5.33%, P = 0.034). After adjusting the model (age, gender, device implantation, prevention of sudden death, LVEDD, LVEF, WBC and CLBBB, hsTNT, etiology, and eGFR) and the model combined with NT-proBNP, the risk of all-cause death was increased by 2.5% and 1.9%, respectively, per ng/ml of sST2. The best sST2 cutoff for predicting all-cause death was 43.42671 ng/ml (area under the curve: 0.72, sensitive: 0.69, and specificity: 0.69). Compared to patients with sST2 levels below 43.42671 ng/ml, the risk of all-cause mortality was higher in those with values above the threshold (5.1% vs. 21.2%, P = 0.002). ST2 level ≥43.42671 ng/ml was an independent predictor of all-cause mortality (HR: 3.30 [95% CI 1.02–10.67]). Age (HR: 1.06 [95% CI: 1.01–1.12]) and increased NT-proBNP per 100 (HR: 1.02 [95% CI: 1.01–1.03]) were also associated with all-cause mortality in ICD patients. Conclusions sST2 level was associated with risk of all-cause mortality, and a threshold of 43.43 ng/ml showed good distinguishing performance to predict all-cause mortality in patients with severe heart failure, recommended for ICD implantation. Patients with sST2 levels more than 43.42671 ng/ml even after ICD implantation should therefore be monitored carefully.
