摘要： 目的分析脉冲多普勒组织成像技术(PW-DTI)所测二尖瓣环收缩期平均位移峰值速度(Sa)作为评价冠心病左心室收缩功能指标的临床价值。方法52例冠心病患者分为经皮冠状动脉介入术(PCI)组33例和未行PCI组19例,PCI组于PCI术前5 d及术后5 d、3个月、6个月随访,非PCI组于冠状动脉造影术后2 d及术后6个月随访;均行PW-DTI及常规超声检查,观察Sa的变化情况。PCI组据射血分数(EF)分成两个亚组:EF≥50%亚组和EF 30%～50%亚组;亚组间进行术前、术后比较;分别分析不同心脏功能患者Sa的变化情况。结果6个月后,PCI组平均Sa明显增高(P<0.001)。平均Sa与EF存在相关性(术前r=0.705,术后r=0.770,均P<0.0001)。结论Sa可作为评价冠心病左室收缩功能的指标。

Abstract: Objective To investigate left ventricular systolic function with mitral annulus motion velocity(Sa) with pulsed-wave Doppler tissue imaging(PW-DTI) in patients with coronary arteriosclerosis disease(CAD) after percutaneous coronary intervention(PCI).Methods 52 patients with CAD,who were determined by coronary artery angiography,were divided into two groups,PCI group(n=33) and non-PCI group(n=19).They were followed up with PW-DTI and conventional echocardiography before and 5 d,3 months and 6 months after intervention in PCI ones,before and 6 months after angiography in non-PCI ones.In PCI group,the patients were divided two subgroups: EF≥50% and EF=30%～50%.Results The Sa improved significantly in PCI group 6 months after intervention(P<0.001).EF correlated with Sa(r=0.705,r=0.770 pre-and post-intervention respectively,P<0.0001).Conclusion Sa can be used to evaluate left ventricular systolic function of CAD patients.
