目的 采用应变率成像技术定量评估冠状动脉支架置入术前后左室局部心肌舒张功能的变化.方法 应用应变率成像技术对56例健康体检者和60例冠心病患者冠状动脉支架置入术前后心尖四腔、两腔、左室长轴切面相应节段局部心肌舒张功能进行定量分析.结果 冠心病患者术前缺血节段心肌应变率曲线中舒张期E、A峰值均小于健康体检者相应心肌节段,术后经治疗的缺血节段心肌舒张期E、A峰值较术前明显增加,差异均有统计学意义(P＜0.05).结论 冠状动脉支架置入术可改善心肌缺血,应变率成像技术能定量评价冠状动脉支架置入术前后左室局部心肌舒张功能的变化.
目的 採用應變率成像技術定量評估冠狀動脈支架置入術前後左室跼部心肌舒張功能的變化.方法 應用應變率成像技術對56例健康體檢者和60例冠心病患者冠狀動脈支架置入術前後心尖四腔、兩腔、左室長軸切麵相應節段跼部心肌舒張功能進行定量分析.結果 冠心病患者術前缺血節段心肌應變率麯線中舒張期E、A峰值均小于健康體檢者相應心肌節段,術後經治療的缺血節段心肌舒張期E、A峰值較術前明顯增加,差異均有統計學意義(P＜0.05).結論 冠狀動脈支架置入術可改善心肌缺血,應變率成像技術能定量評價冠狀動脈支架置入術前後左室跼部心肌舒張功能的變化.

Objective To investigate the application of strain rate imaging in quantitative assessment of left ventricular regional diastolic function after intracoronary stent implantation.Methods Fifty-six healthy person and 60 patients with coronary artery disease were performed quantitative assessment of left ventricular regional diastolic function by apical four chamber view,apical two chamber view and left ventricular long axis view before and after intracoronary stent implantation using strain rate imaging.Results Compared with those of normal myocardium,the peaks of strain rate curve at diastole of ischemic myocardium were reduced,and were increased after operation (P ＜ 0.05).Conclusions Intracoronary stent implantation can significantly improve the blood supply to the ischemia myocardium.Strain rate imaging can quantitatively analyze the changes of left ventricular regional diastolic function.
