【摘要】：目的采用二维斑点追踪技术(STE)评价急性心肌梗死(AMI)患者不同冠脉病变部位对左心房功能的影响。方法根据冠状动脉造影显示的犯罪血管将患者分为LAD组,LCX组及RCA组,其中LAD组31例,LCX组22例,RCA组26例。分别在PCI术后72h内行超声检查,检测左心房整体心肌收缩期纵向应变(LS)和应变率(LSR-s)、舒张早期应变率(LSR-e)及舒张晚期应变率(LSR-a)。PCI再通1个月后随访。结果 LCX组左心房LS及LSR-s较LAD组及RCA组明显减低(P0.05)。三组左心室舒张功能、左心房容积及射血分数无显著差异。PCI再通1个月后,三组左心房功能无显著差异。结论 LCX组闭塞患者左心房功能较LAD组及RCA组闭塞患者更加减低,PCI再通后,左心房功能恢复。
[Abstract]:Objective to evaluate the effects of different coronary lesions on left atrial function in patients with acute myocardial infarction (AMI) by using two dimensional speckle tracing technique. Methods according to the criminal vessels displayed by coronary angiography, the patients were divided into LAD group and RCA group. Among them, 31 cases in LAD group and 22 cases in RCA group were examined by ultrasound within 72 hours after PCI. The left atrial systolic longitudinal strain (LSs), strain rate (LSR-S), early diastolic strain rate (LSR-e) and late diastolic strain rate (LSR-aI) and late diastolic strain rate (LSR-A 路PCI) were measured. Results the left atrial LS and LSR-s in LCX group were significantly lower than those in LAD group and RCA group. Left ventricular diastolic function, There was no significant difference in left atrial volume and ejection fraction. There was no significant difference in left atrial function among the three groups one month after PCI recanalization. Conclusion the left atrial function in LCX group is significantly lower than that in LAD group and RCA group.
