Abstract

Background: Atrial fibrillation (AF) is a common arrhythmia causing serious health complications. Catheter ablation is used to treat AF, but the risk of recurrence is high. The DR-FLASH score, which predicts recurrence, has limited sensitivity and specificity. Left atrial mechanical dispersion (LAMD) is an effective index that reflects the synchronisation of left atrial mechanical movement and the degree of early remodelling.

Objective: This study aimed to assess the predictive value of LAMD and the DR-FLASH score for late recurrence after ablation.

Methods: The general clinical data, structural, and functional parameters of both the recurrence group and the non-recurrence group were collected. Univariate and multivariate logistic regression analysis explored the independent predictors of late recurrence after AF ablation. The ROC curve was used to evaluate the effectiveness of LAMD and DR-FLASH score on recurrence after AF ablation.

Results: The study included 102 AF patients and 31 healthy controls. LAMD was found to be an independent predictor of recurrence, and combining it with the DR-FLASH score improved predictive efficiency, with an area under the curve (AUC) of 0.875, sensitivity of 77.8%, and specificity of 88.0%.

Conclusion: LAMD combined with the DR-FLASH score can help identify high-risk patients and potentially reduce recurrence rates.

实时三维超声心动图评价左房机械离散度结合DR-FLASH评分预测阵发性心房颤动消融后晚期复发

背景：心房颤动是一种常见的心律失常，可引起严重的健康并发症。导管消融用于治疗房颤，但其复发风险高。预测复发的DR-FLASH评分具有有限的敏感性和特异性。左房机械离散度（LAMD）是反映左房机械运动同步性和早期重构程度的有效指标。目的：探讨LAMD及DR-FLASH评分对消融术后晚期复发的预测价值。方法：收集复发组和非复发组的一般临床资料、结构及功能参数。单因素和多因素logistic回归分析探讨房颤消融后晚期复发的独立预测因素。采用ROC曲线评价LAMD和DR-FLASH评分对房颤消融后复发的影响。结果：本研究纳入102例房颤患者和31例健康对照。LAMD是复发的独立预测因子，与DR-FLASH评分结合可提高预测效率，曲线下面积（AUC）为0.875，敏感性为77.8%，特异性为88.0%。结论：LAMD联合DR-FLASH评分有助于识别高危患者，降低复发率。
