Association between omentin-1 and heart failure with preserved ejection fraction in Chinese elderly patients
CLINICAL CARDIOLOGY(2024)
Abstract
Background: Omentin-1 is a novel adipokine and is associated with chronic inflammation and cardiovascular diseases. However, it remains unclear whether omentin-1 levels are associated with diagnostic significance in elderly patients with heart failure with preserved ejection fraction (HFpEF). This study aimed to investigate the correlation between omentin-1 and HFpEF in Chinese elderly patients.Hypothesis: Omentin-1 may be invovled in HFpEF and there may be a difference of omentin-1 levels between HFpEF and control.Methods: 217 subjects were selected, including 115 patients with HFpEF and 102 control subjects. Enzyme-linked immuno sorbent assay (ELISA) was used to detect plasma levels of omentin-1, tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6). The receiver operating characteristics (ROC) curve was used to examine the diagnostic performance of omentin-1 in HFpEF.Results: The levels of omentin-1 decreased significantly in the HFpEF group (14.02 +/- 8.35 vs. 19.74 +/- 8.45 ng/mL, p < .001), while NT-proBNP, IL-6, and TNF-alpha levels were significantly increased in the HFpEF group compared with the control group. Spearman correlation analysis showed that omentin-1 levels were negatively correlated with E/e' (r = -.340, p < .001). The multivariate logistic regression analysis indicated that omentin-1 was an independent protective factor for HFpEF (odd ratio = 0.948, 95% confidence interval [CI] 0.905-0.993, p = .025). Omentin-1 levels were negatively correlated with NT-proBNP (r = -.273, p < .001) and TNF-alpha (r = -.221, p = .001). Diagnostic efficiency by ROC curve analysis in the patients with HFpEF showed that the area under the curve (AUC) for omentin-1 was equivalent to NT-proBNP (AUC: 0.734, 95%CI 0.667-0.802; AUC: 0.800, 95%CI 0.738-0.861). Subgroup analysis showed that in the patients between the age of 70 and 80, the predictive capability of omentin-1 was stronger than NT-proBNP (AUC: 0.809, 95%CI 0.680-0.937; AUC: 0.674, 95%CI 0.514-0.833).Conclusions: Omentin-1 levels which were associated with inflammation, were decreased in the HFpEF patients. It could be regarded as a valuable biomarker for the occurrence and development of HFpEF in elderly patients.
