Reduced left atrial wall motion velocity measured during AF (LAWMV) indicates left atrial remodeling. The aim of this study was to investigate whether LAWMV assessed with tissue Doppler imaging during atrial fibrillation (AF) predicts sinus rhythm (SR) maintenance after direct current cardioversion (DCCV) for persistent AF. The study included 126 patients who underwent DCCV and were followed for 12 months. At 12 months, maintained SR was reported in 55 patients (43.7%). We noted that LAWMV was higher in patients with maintained SR at 12 months than in those with recurrent AF (3.69 ± 0.84 vs. 2.86 ± 1.09; < 0.001). In the multivariable regression model containing echocardiographic variables, LAWMV was an independent predictor of SR maintenance at 12 months (odds ratio [OR] 1.72, 95% confidence interval [CI] 1.1-2.69; = 0.017). Similarly, LAWMW was an independent predictor of SR maintenance at 12 months (OR 1.81, 95% CI 1.19-2.77; = 0.006) in the multivariate regression model containing both echocardiographic and clinical variables. LAWMV predicts SR maintenance after DCCV for persistent AF. Echocardiographic markers of left atrial mechanical remodeling are better at predicting SR maintenance than markers of structural remodeling.
在房颤期间测量的左心房壁运动速度降低（LAWMV）表明左心房重构。本研究旨在探讨在用组织多普勒成像评估房颤期间的 LAWMV 是否可预测持续性房颤患者直流电复律（DCCV）后窦性心律（SR）的维持。该研究纳入了 126 名接受 DCCV 并随访 12 个月的患者。在 12 个月时，报告有 55 名患者（43.7%）维持 SR。我们注意到，在 12 个月时维持 SR 的患者的 LAWMV 高于复发性房颤患者（3.69±0.84 比 2.86±1.09；<0.001）。在包含超声心动图变量的多变量回归模型中，LAWMV 是 12 个月时 SR 维持的独立预测因子（比值比[OR]1.72，95%置信区间[CI]1.1-2.69；=0.017）。同样，在包含超声心动图和临床变量的多变量回归模型中，LAWMW 是 12 个月时 SR 维持的独立预测因子（OR 1.81，95%CI 1.19-2.77；=0.006）。LAWMV 可预测持续性房颤患者 DCCV 后的 SR 维持。左心房机械重构的超声心动图标志物比结构重构的标志物更能预测 SR 的维持。
