    Application of the 3-dimensional speckle tracking imaging on the evaluation of left ventricular wall motion in patients with coronary artery disease before and after PCI

      摘要
    • 摘要: 目的:应用三维斑点追踪显像技术(3D-STI)观察冠心病(CAD)经皮冠状动脉介入术(PCI)治疗前后左心室收缩功能的变化。方法:对50例CAD患者(CAD组)分别于 PCI 治疗前、治疗后3～7 d内、治疗后3个月时,及30名健康体检者(对照组)进行3D-STI分析,测量出左心室壁各心肌节段的圆周应变峰值(CSpeak)。结果:与对照组比较,CAD组PCI治疗前及治疗后的CSpeak均降低;与 PCI治疗前比较,PCI治疗后3～7 d内的CSpeak增高;PCI治疗后3个月上述指标增高变化更为显著(P<0.01)。结论:冠心病患者的心肌变形能力下降,经PCI 治疗后可获得改善,同时3D-STI可以准确定量评价冠心病患者左心室心肌收缩功能的异常。

       

      Abstract: Objective:To observe the systolic function of left ventricular in patients with coronary artery disease(CAD) before and after the percutaneous coronary intervention(PCI) by 3-dimensional speckle tracking imaging(3D-STI).Methods:The 3D-STI data of 50 CAD patients(CAD group) before and after 3 to 7 days and 3 months of PCI and 30 healthy people(control group) were analyzed.The circumferential strain peaks(CSpeak) of each myocardial segment of left ventricular wall were measured.Results:Compared with the control group, the CSpeak in CAD group before and after PCI was decreased.Compared with before PCI, the CSpeak in CAD group after 3 to 7 days of PCI was increased.After 3 months of PCI, changes of the CSpeak in CAD group were significant(P<0.01).Conclusions:The myocardial deformation ability in patients with coronary artery disease is decreased, which can be improved after PCI.The 3D-STI can accurately assess the left ventricular systolic function in patients with coronary artery disease.
