摘要: 本研究探讨了斑点追踪超声心动图对急性心肌梗死(AMI)患者接受经皮冠状动脉介入(PCI)术后左心室重构(LVR)的评价作用。收集96例接受急诊PCI术的AMI患者,分为LVR组和未LVR组,比较两组斑点追踪超声心动图参数差异。结果显示,患者PCI术后LVR发生率为35.42%。LVR组术后6个月LVESV、LVEDV较术后24 h增大,LVEF减小(P<0.05)。未LVR组术后6个月LVEF较术后24 h明显提高(P<0.05)。两组PCI术后6个月LVESV、LVEDV、LVEF比较,差异均有统计学意义(P<0.05)。LVR组左心室GLS、GRS、GCS均小于未LVR组,左心室纵向、径向Ts-SD大于未LVR组(P<0.05)。多元Logistic分析显示GLS、GRS、GCS是AMI患者PCI术后LVR的独立预测因素,ROC曲线分析显示,AUC由大到小依次为GLS、GCS和GRS。因此,斑点追踪超声心动图测量GLS、GCS和GRS可有效预测AMI患者PCI术后LVR的发生风险,且GLS预测评估效果最佳。

Abstract: This paper discussed the effect of spot tracking echocardiography on left ventricular remodeling (LVR) after percutaneous coronary intervention(PCI) in acute myocardial infarction(AMI) patients. 96 patients with AMI undergoing emergency PCI were selected and divided into LVR group and non-LVR group, and spot tracking echocardiographic parameters of 24 h and 6 months after PCI were collected. It is found that the rate of LVR after PCI in all patients was 35.42%. Compared with the postoperative parameters of 24 h after PCI, LVESV and LVEDV in LVR group after PCI for 6 months increased but LVEF decreased significantly, while LVEF in non-LVR group after PCI for 6 months was higher significantly (P<0.05). LVESV, LVEDV and LVEF after PCI for 6 months of the two groups had significant differences (P<0.05). Compared with non-LVR group, left ventricular GLS, GRS and GCS in LVR group were lower significantly, left ventricular longitudinal and radial Ts-SD were higher significantly (P<0.05). Multivariate logistic analysis showed that GLS, GRS and GCS were independent predictors of LVR after PCI in AMI patients. ROC curve analysis showed that AUC were gradually decreased as GLS>GCS>GRS. In a word, GLS, GCS and GRS examined by spot tracking echocardiography can objectively predict LVR risk after PCI in AMI patients, and GLS is the most significant predictor.
