Abstract
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.
