摘要:
目的:应用定量组织速度成像(QTVI)技术,评价冠状动脉搭桥(CABG)术前、后,搭桥节段心肌长轴收缩功能的变化。方法:15例冠心病患者CABG术前1d、术后10d、3个月分别测量搭桥心肌长轴方向等容收缩期速度(VIVC,包括正向峰值速度和负向峰值速度)、收缩期峰值速度(Vs),比较手术前、后该参数的变化。结果:搭桥节段心肌术后不同时期VIVC正向峰值速度(VIVC+)和Vs较术前明显增高。术后10d、3个月VIVC+ 变化均较Vs变化显著(术后10d P=0.0499,术后3个月P=0.0427)。结论:QTVI可定量评价局部左室壁动态功能,为无创定量评价CABG术前、后相关节段心肌收缩功能提供一种简单和敏感的方法。
Abstract:
AIM: To investigate the regional myocardial systolic function at risk zone before and after Coronary artery bypass graft (CABG) using quantitative tissue velocity imaging (QTVI). METHODS: 15 patients with coronary artery disease were performed in 1 day before CABG, 10 days and 3 months after CABG with QTVI. Peak of early systolic velocity (Vs), velocity of isovolumic contraction phase (VIVC, including peak positive and peak negative) were measured in longitudinal direction of the apical long axis, apical two chamber or four chamber. RESULTS: The peak positive of VIVC (VIVC+) and Vs at risk zone were remarkably increased in different periods after CABG. VIVC+ changed more significantly compared with Vs in 3 months after CABG (P=0.0381). CONCLUSIONS: QTVI techniques can be useful in the quantitative assessment of regional left ventricular wall dynamics and hence, offers a sensitive and simple non invasive method to analyze regional myocardial systolic function before and after CABG.
