Objective: To explore whether the serum CCN5 levels associated with atrial fibrosis can predict LVZ in patients with atrial fibrillation. Methods: In this study, 79 patients with sinus rhythm (control group) and 114 patients with atrial fibrillation (atrial fibrillation group) who received radiofrequency cardiac ablation for the first time in Yantai Yuhuangding Hospital between June 2023 and January 2024 were enrolled. General data, biochemistry, electrocardiogram, cardiac ultrasound and other clinical data were collected. Left atrial stroma voltage mapping was performed in patients with atrial fibrillation and LVZ area ratio was calculated. Patients were divided into group A (LVZ < 6%) and group B (LVZ ≥ 6%) according to whether LVZ was greater than 6%. The expression level of CCN5 in peripheral blood was measured by enzyme-linked immunosorbent assay. T test was used to compare the CCN5 expression level between the control group and the atrial fibrillation group. Pearson or Spearman correlation analysis was used to explore the correlation between CCN5 and clinical data. Binary Logistic regression analysis was used to determine the risk factors affecting the LVZ, and receiver operating characteristic (ROC) analysis was down to determine the cut-off value of CCN5 to predict LVZ. Results: The level of CCN5 in patients with atrial fibrillation was lower than in control group (32.43 ± 6.15 vs. 25.46 ± 4.97, P < 0.001). For atrial fibrillation patients with LVZ < 6%, blood CCN5 expression levels were lower in patients with LVZ ≥ 6% (30.10 ± 6.75 vs. 24.75 ± 3.49, P < 0.001). In patients with atrial fibrillation, CCN5 was negatively correlated with BNP level, left atrial diameter and left atrial low-voltage %K 心房颤动， %K 心脏射频消融术， %K CCN5， %K 左房低电压区， %K 生物标志物
