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。

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.
