摘　　要：目的 本研究旨在分析左心耳(LAA)收缩期峰值应变率(SSR)与阵发性房颤(PAF)射频消融术(RFA)后复发的关系。方法 选取在RFA术前接受经食道和经胸超声心动图检查的PAF患者,采集各项评估参数,应用单因素和多因素Logistic回归分析,获得阵发性房颤RFA术后复发的独立预测因素。结果 两组间比较左心房前后径(LAD)、内侧壁的收缩期峰值应变率(SSR-M)、外侧壁的收缩期峰值应变率(SSR-L)差异有统计学意义,复发组LAD大于未复发组,复发组SSR-M、SSR-L均小于未复发组;在多因素Logistic回归分析中,调整了混杂因素后,SSR-M和SSR-L是阵发性房颤RFA术后复发的独立预测因素。结论 通过组织多普勒心动图分析LAA应变率有助于阵发性房颤RFA术的临床决策。Objective The aim of this study was to analyze the relationship between systolic strain rate(SSR)of the left atrial appendage(LAA)and recurrence after radiofrequency ablation(RFA)of paroxysmal atrial fibrillation(PAF).Methods In patients who underwent transesophageal and transthoracic echocardiography before RFA of PAF,various assessment parameters were collected,and univariate and multivariate Logistic analyses were applied to obtain independent predictors of recurrence after RAF of PAF.Results The differences in left atrial diameter(LAD),SSR of the medial wall(SSR-M)of LAA and SSR of the lateral wall(SSR-L)of LAA were statistically significant when comparing the two groups,with LAD being greater in the relapse group than in the non-relapse group,and SSR-M and SSR-L being smaller in the relapse group than in the non-relapse group;In multivariate Logistic analysis,after adjusting for confounders,SSR-M and SSR-L of LAA were independent predictors for recurrence after RFA of PAF.Conclusions Analysis SSR of LAA by tissue Doppler echocardiography can be helpful in clinical decision-making for RFA of PAF.
