【摘要】：目的探讨二维斑点追踪技术(STI)评价急性广泛前壁心肌梗死行经皮冠状动脉介入治疗(PCI)前、后左室心肌运动功能的临床应用价值。方法选择2012年12月—2013年12月佳木斯大学附属第一医院心内科行PCI的急性广泛前壁心肌梗死患者25例为病例组,选择同期30例健康医务人员及患者家属作为对照组。对照组与病例组PCI前及PCI后1、4、12周时行二维超声检查,对比分析两组各心肌节段收缩期纵向应变(LS)、径向应变(RS)、圆周应变(CS)的变化及差异。结果病例组应变-时间曲线杂乱,对照组应变-时间曲线分布均一。病例组PCI后1周LS、RS、CS峰值与术前比较,差异无统计学意义(P0.05);病例组PCI后4、12周LS、RS、CS峰值均较术前、PCI后1周升高,病例组PCI后12周LS、RS、CS峰值均较PCI后4周升高,差异有统计学意义(P0.05)。结论二维STI可以定量评价急性广泛前壁心肌梗死患者行PCI前、后左室心肌的运动功能,可作为评价PCI疗效的参考指标。
[Abstract]:Objective to evaluate the clinical value of two dimensional speckle tracing technique (STI) in evaluating left ventricular motor function before and after percutaneous coronary intervention (PCI) in patients with acute extensive anterior myocardial infarction (AMI).Methods from December 2012 to December 2013, 25 patients with acute extensive anterior myocardial infarction (AMI) treated with PCI in Department of Cardiology, first affiliated Hospital of Jiamusi University were selected as case group, and 30 healthy medical personnel and family members of the patients were selected as control group.Two dimensional ultrasonography was performed before PCI and 12 weeks after PCI in the control group and the case group. The changes and differences of longitudinal strain, radial strain and circumferential strain were compared between the two groups.Results the strain-time curve of the case group was disorderly, and the strain-time curve of the control group was uniform.There was no significant difference in the peak value of PCI 1 week after PCI compared with that before operation, but there was no significant difference between the two groups (P 0.05), but the peak value at 12 weeks after PCI in the case group was higher than that at 1 week after PCI, and the peak value at 12 weeks after PCI in the case group was higher than that at the 4th week after PCI, and the difference was statistically significant (P 0.05).Conclusion Two-dimensional STI can be used to quantitatively evaluate the left ventricular motor function in patients with extensive anterior wall acute myocardial infarction before and after PCI, and can be used as a reference index for evaluating the curative effect of PCI.
