摘　　要：目的探讨心肌造影联合二维斑点追踪预测心梗PCI术后发生不良心血管事件的价值。方法选择2023年1月-2024年5月本院心内科收治的接受PCI术后患者80例为研究对象。根据心肌灌注评分指数(myocardial perfusionscore index,MPSI)分成两组:MPSI≤1.5为心肌灌注对照组;MPSI>1.5为心肌灌注观察组。比较两组术后1个月左室心肌超声造影结果及二维斑点追踪检测结果指标,分析MPSI、左室整体纵向应变单独及联合预测心梗PCI术后发生不良心血管事件的价值。结果观察组LVEF、左室整体纵向应变和室间隔运动速度均低于对照组(P<0.05),LVIDd、LAD和LAVmax均高于对照组(P<0.05),MPSI、左室整体纵向应变单独预测心梗PCI术后发生不良心血管事件的敏感度和特异度均低于联合检查,且联合检查预测心梗PCI术后发生不良心血管事件的AUC面积大于MPSI、左室整体纵向应变单独检查。结论左室心肌造影联合二维斑点追踪预测心梗患者PCI术后发生不良心血管事件具有较为理想的价值,值得临床重视。Objective To explore the value of myocardial contrast imaging combined with two-dimensional speckle tracking in predicting adverse vascular events after PCI for myocardial infarction.Methods 80 patients who underwent PCI from January 2023 to May 2024 were selected as the research object.According to myocardial perfusion score index(MPSI),they were divided into two groups:MPSI≤1.5 as myocardial perfusion control group;MPSI>1.5 was the observation group of myocardial perfusion.The results of left ventricular myocardial contrast echocardiography and two-dimensional speckle tracking test were compared between the two groups one month after operation,and the value of MPSI and global longitudinal strain of left ventricle in predicting the occurrence of adverse cardiovascular events after PCI of myocardial infarction was analyzed.Results LVEF,left ventricular overall longitudinal strain and interventricular septal velocity in the observation group were lower than those in the control group(P<0.05),while LVIDd,LAD and LAVmax were higher than those in the control group(P<0.05).The sensitivity and specificity of MPSI and global left ventricular longitudinal strain in predicting the occurrence of cardiovascular events after PCI were lower than those in the joint examination,and the AUC area of joint examination in predicting the occurrence of cardiovascular events after PCI was larger than that of MPSI and left ventricular overall longitudinal strain alone.Conclusion Contrast-enhanced left ventricular ultrasound combined with two-dimensional speckle tracking has ideal value in predicting the occurrence of adverse cardiovascular events in patients with myocardial infarction after PCI,which deserves clinical attention.
