BACKGROUND: A number of circulating biomarkers are currently utilized for the diagnosis of chronic heart failure with preserved ejection fraction (HFpEF). However, due to HFpEF heterogeneity, the accuracy of these biomarkers remains unclear. AIMS: This study aimed to systematically determine the diagnostic accuracy of currently available biomarkers for chronic HFpEF. METHODS: PubMed, Web of Science, MEDLINE and SCOPUS databases were searched systematically to identify studies assessing the diagnostic accuracy of biomarkers of chronic HFpEF with left ventricular ejection fraction (LVEF) ≥50%. All included studies were independently assessed for quality and relevant information was extracted. Random-effects models were used to estimate the pooled diagnostic accuracy of HFpEF biomarkers. RESULTS: The search identified 6145 studies, of which 19 were included. Four biomarkers were available for meta-analysis. The pooled sensitivity of B-type natriuretic peptide (BNP) (0.787, 95% confidence interval [CI] 0.719-0.842) was higher than that of N-terminal pro-BNP (NT-proBNP) (0.696, 95% CI 0.599-0.779) in chronic HFpEF diagnosis. However, NT-proBNP showed improved specificity (0.882, 95% CI 0.778-0.941) compared to BNP (\0.796, 95% CI 0.672-0.882). Galectin-3 (Gal-3) exhibited a reliable diagnostic adequacy for HFpEF (sensitivity 0.760, 95% CI 0.631-0.855; specificity 0.803, 95% CI 0.667-0.893). However, suppression of tumorigenesis-2 (ST2) displayed limited diagnostic performance for chronic HFpEF diagnosis (sensitivity 0.636, 95% CI 0.465-0.779; specificity 0.595, 95% CI 0.427-0.743). CONCLUSION: NT-proBNP and BNP appear to be the most reliable biomarkers in chronic HFpEF with NT-proBNP showing higher specificity and BNP showing higher sensitivity. Although Gal-3 appears more reliable than ST2 in HFpEF diagnosis, the conclusions are limited as only three studies were included in this meta-analysis.
