Objective: Our study was to explore the roles between serum soluble suppression of tumorigenicity 2 (sST2) and N-terminal pro-brain natriuretic peptide (NT-proBNP) while evaluating ventricular function to properly diagnose chronic heart failure (CHF).
Methods: In total, 197 CHF patients were recruited and classified into ventricular function's II, III, and IV groups, and 106 healthy people into normal control group. To detect concentrations of Sst2 and NT-proBNP, ELISA and electro-chemiluminescence immuno assay were implemented. An automatic biochemical analyzer was used to determine the levels of the following: blood urea nitrogen (BUN), creatinine (Cr), alanine aminotransferase (ALT), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and uric acid (UA). A receiver operating characteristic (ROC) curve was adopted to detect the diagnostic value sST2 and NT-ProBNP in CHF and the logistic regression analysis involving the risk factors of CHF.
Results: Serum sST2 and NT-proBNP concentrations were increased significantly in the ventricular function's II, III, and IV groups in a manner dependent on concentration as opposed to the manner the normal control group occupied. The area under the curve (AUC) of sST2, found NT-proBNP and sST2+NT-proBNP to be 0.942 (95% CI: 0.917-0.966), 0.920 (95% CI: 0.891-0.948), and 0.968 (95% CI: 0.953-0.984), respectively. sST2, NT-proBNP, UA, and Cr were verified as important risk factors of CHF.
Conclusion: Serum sST2 and NT-ProBNP could act as diagnostic indicators for CHF.

Changes in sST2 and NT-proBNP levels predict early cardiac arrhythmia in breast cancer patients treated with anthracycline-containing chemotherapies.

Background: Cardiovascular biomarkers are crucial for monitoring cancer therapy-related cardiac toxicity, but the effects on early stage are still inadequate. To screen biomarkers in patients with breast cancer who receive anthracycline-containing chemotherapy, we studied the behavior of six biomarkers during chemotherapy and their association with chemotherapy-related cardiac toxicity.
Methods: In a prospective cohort of 73 patients treated with anthracycline-containing chemotherapy, soluble suppression of tumorigenicity 2 (sST2), high-sensitivity cardiac troponin T, N-terminal pro-B-type natriuretic peptide (NT-proBNP), myoglobin, creatine kinase isoenzyme MB, and heart-fatty acid binding protein were measured at baseline, during chemotherapy cycle (C1-C6).

Background: We explored the link between sST2 and NT-proBNP levels and postoperative atrial fibrillation (POAF) incidence in non-cardiac surgery patients in this study.
Methods: The research involved 302 participants over 40 years old who underwent medium and/or high-risk non-cardiac surgeries. These patients were divided into two groups: those who developed POAF and those who did not.

Backround And Aims: Early evaluation of cardiac remodeling may be useful in predicting heart failure in patients with arterial hypertension. The identification of biomarkers as useful clinical tools in this regard is ongoing. The aim of this study was to evaluate the association of selected cardiac biomarkers levels with parameters of cardiac structure and function in patients with arterial hypertension.

The gold standard for diagnosis is represented by the measurement of LV end-diastolic pressure (LVEDP) during cardiac catheterization, but it has the disadvantage of being an invasive procedure. This study aimed to investigate the correlation between LVEDP and cardiac serum biomarkers such as natriuretic peptides (mid-regional pro-atrial natriuretic peptide [MR-proANP], B-type natriuretic peptide [BNP], and N-terminal prohormone BNP [NT-proBNP]), soluble ST2 (sST2), galectin-3 and mid-regional pro-adrenomedullin (MR-proAMD).

Background: The use of biochemical markers in ADHF is considered valuable both in the diagnosis and treatment of diseases and in follow-up. This study aimed to investigate the prognostic power of serum sST2 and NT-proBNP levels in predicting long-term mortality in patients with ADHF using serial measurement.
Methods: A total of 122 patients with ADHF were included in this prospective study.
