摘　　要：目的探究四维斑点追踪显像技术(Four-Dimensional Speckle Tracking Imaging,4D-STI)评估急性心肌梗死(Acute Myocardial Infarction,AMI)PCI术后的左心功能的价值。方法收集经皮冠状动脉介入治疗(Percutaneous Coronary Intervention,PCI)的患者33例,将其分为术前组、术后组,另外选择健康志愿者45例作为对照组,对三组分别进行常规超声心动图和4D-STI检查,分别测出用于评估左房和左室相关的心功能参数,对三组测得的左房和左室心功能参数分别进行比较。结果AMI PCI术前组与术后组和对照组相比,差异均具有统计学意义(P<0.05);左室功能相关参数比较,发现AMI PCI术前组左心室舒张末内径、左心室收缩末内径均比术后组和对照组增大,左心室射血分数均比术后组和对照组减小,且差异均具有统计学意义(P<0.05)。结论4D-STI技术可以对AMI患者经PCI术治疗后左房和左室功能的恢复情况进行定量评价,为PCI疗效评定和CHD预后判定提供理论依据。另外,对AMI患者进行及时有效的PCI治疗后患者的左室功能大致可恢复正常。Objective To explore the value of Four-dimensional speckle tracking imaging(4D-STI)in evaluating left heart function after PCI in acute myocardial infarction.Methods 33 patients with percutaneous coronary intervention(PCI)were collected and divided into the preoperative group and the postoperative group,and 45 healthy volunteers were chosen as control group.Conventional echocardiography and 4D-STI examinations were performed in the three groups respectively,and cardiac function parameters used to evaluate left atrial and left ventricular were measured and compared in the three groups respectively.Results Compared with the postoperative group and the control group,the difference of AMI PCI group was statistically significant(P<0.05).Compared with the control group and the postoperative group,the LVEDD and the LVESD of the AMI PCI group were both increased,and the LVEF decreased compared with the postoperative group and the control group,with statistically significant differences(P<0.05).Conclusion 4D-STI technology can quantitatively evaluate the recovery of left atrial and left ventricular functions in patients with acute myocardial infarction after PCI,providing theoretical basis for the evaluation of efficacy of PCI and the prognosis determination of CHD).In addition,the left ventricular function of AMI patients can be restored to normal after timely and effective PCI treatment.
