摘　　要：目的:探讨二维斑点追踪显像(2D-STI)技术评价冠状动脉慢性完全闭塞病变(CTO)患者经皮冠状动脉介入治疗(PCI)前后左心室局部及整体功能变化的价值。方法:纳入23例CTO患者,分别于PCI前,术后1天、3个月和6个月行超声心动图检查测左心室射血分数,同时应用2D-STI获得左心室整体纵向应变值(GLS)。结果:与术前左心室射血分数(59.29±12.15)%相比,术后3个月左心室射血分数(60.00±12.35)%及术后6个月左心室射血分数(61.37±11.80)%均升高,差异均有统计学意义(P均<0.05)。与术前GLS(-12.77±1.07)%相比,术后1天GLS(-13.23±1.64)%、术后3个月GLS(-15.67±1.91)%和术后6个月GLS(-16.97±2.07)%均降低,差异均有统计学意义(P均<0.05)。结论:PCI能有效改善CTO患者左心功能。2D-STI技术可早期、定量地评价这一变化。Objective：To explore the value of two-dimensional speckle tracking echocardiographic imaging（2D-STI） for assessing partial and global left ventricular functional changes at pre-and post-percutaneous coronary intervention（PCI） in patients with chronic total coronary occlusion.Methods：Echocardiograph was conducted in 23 chronic total coronary occlusion patients at pre-PCI and 1 day,3,6 months post-PCI to examine left ventricular ejection fraction（LVEF）,meanwhile 2D-STI was applied to obtain the global longitudinal strain（GLS） value of left ventricle.Results：In all 23 patients,for LVEF,compared with pre-PCI（59.29±12.15） %,it was increased at 3 and 6 months post-PCI（60.00±12.35） % and（61.37±11.8） % respectively,all P0.05;for GLS value,compared with pre-PCI（-12.77 d wit） %,it was decreased at 1 day and 3,6 months post-PCI（-13.23ecrea） % and（-15.67ecrea） %,（-16.97ecrea） % respectively,all P〈0.05.Conclusion：PCI could effectively improve left ventricular function in patients with chronic total coronary occlusion,2D-STI technology may quantitatively assess those changes at the early stage.
