Serum chemerin and Gal-3 expression levels are valuable for predicting patients with atrial fibrillation complicated with left atrial fibrosis
Objective:To explore the predictive value of serum chemerin and Galectin-3(Gal-3)expression levels in atrial fibrillation(AF)complicated with left atrial fibrosis.Methods:A total of 138 patients with AF who underwent radiofre-quency catheter ablation for the first time in our hospital from February 2020 to June 2021 were enrolled.According to the total area of left atrium occupied by low-voltage areas(LVAS),patients were divided into LVAS<10%group(73 cases)and LVAS≥10%group(65 cases).Serum chemerin and Gal-3 levels were detected by enzyme-linked immunosorbent as-say(ELISA),and their relationship with AF complicated with left atrial fibrosis was analyzed.The ROC curve was drawn to analyze their predictive value for AF complicated with left atrial fibrosis.Results:Persistent AF,smoking,drinking,TG,LAD,LVEF,E/A,E/e',serum chemerin,serum Gal-3 were associated with AF complicated with left atrial fibrosis(P<0.05).Pearson correlation analysis showed that serum chemerin and Gal-3 levels were positively correlated with left atrial fibrosis in patients with AF(P<0.01).The results of multivariate Lgistic regression analysis showed that persistent AF,decreased LAD,increased serum chemerin level and serum Gal-3 level were independent risk factors for left atrial fibrosis in patients with AF(OR>1,P<0.05).When the cut-off value of serum chemerin level was 147.26 ng/mL,the area under the ROC curve of predicting AF complicated with left atrial fibrosis was 0.73,and the sensitivity and specificity were 76.25%and 69.33%,respectively.When the cut-off value of serum Gal-3 level was 56.39 pg/mL,the area under the ROC curve for predicting AF complicated with left atrial fibrosis was 0.71,and the sensitivity and specificity were 74.46%and 68.29%,respectively.The area under the ROC curve for predicting AF complicated with left atrial fibrosis was 0.77.The sensitivity and specificity were 79.37%and 69.28%,respectively.Conclusion:Serum chemerin and Gal-3 levels are positively correlated with left atrial fibrosis in patients with AF complicated with left atrial fibrosis,and their levels have a good predictive value for predicting left atrial fibrosis in patients with AF complicated with left atrial fibrosis.
