摘　　要：目的应用二维斑点追踪成像(STI)技术分析左心房应变值与冠状动脉旁路移植术(CABG)术后新发房颤的相关性。方法应用STI技术测量行CABG的42例冠心病患者左房收缩功能,按患者是否新发房颤分为房颤组(n=13)和非房颤组(n=29),对2组相关因素做单因素和多因素分析。结果与非房颤组比较,术后房颤组LAD较大,E较高,A较低,E/A较高,左心室收缩期左心房长轴方向所测整体应变(Ss)及心房收缩期左心房长轴方向整体应变(Sa)和左心房各节段应变率(SRs)均较低,差异有统计学意义(均P<0.05)。结论术前应用STI技术测得的左心房应变值与CABG术后房颤相关。AIM To use ultrasound speckle tracking imaging （STI） in studying the correlation between left atrial strain value and new onset atrial fibrillation （AF） after coronary artery bypass grafting （CABG）. METHODS Changes of left atrial systolic functions were measured by STI technique in 42 coronary heart disease （CHD） patients and 30 normal subjects were used as the control group. RESULTS Compared with those in the control group, LAD was larger, E was higher, A was lower, E/A was higher, and Ss, Sa and SRs were lower in postoperative AF group, with statistically significant difference （P〈0.05）. Compared with those in the control group, no significant difference was found in the above indexes in the postoperative non-AF group. There was statistically significant difference in the above indexes between the postoperative AF group and postoperative non-AF group （P〈0.05）. CONCLUSION Preoperative STI technique used to analyze the value of left atrial strain predicts effectively the occurrence of atrial fibrillation after CABG.
