摘要
目的:评估二维超声(2-DE)检测经皮冠脉介入治疗术(PCI)术后二周存活心肌的价值。方法:18例冠心病患者均行PCI。术前一同内,行常规2-DE检查,并于术后二周及三月复查2-DE。以术后三月2-DE检查结果为评价存活心肌标准。得出PC术前、术后二周,三月射血分数(EF)、室壁运动计分指数(WMSI)数值及存活心肌节段数,并进一步明确三者之问的相互关系。结果:PCI术后EF变化值(ΔEF)与再通血管相关存活心肌节段数呈中度以上正相关(r=0.63),△EF与△WMSI呈中度以上负相关(r=-0.67)。PCI二周2-DE检测存活心肌方面有较高的敏感性(91.1％)、特异性(80％)、准确性(89.9％)。结论:PCI后二周2-DE识别存活心肌有较高的灵敏性。
Objective: To assess the value detecting the viable myocardium by two-dimension echocardiography (2 -DE) after percutaneous coronary intervention two weeks in patients with coronary artery disease (CAD). Methods: Eighteen CAD patients were checked by 2 - DE before PCI and after PCI two weeks and three months again. Detect-ing results of 2 - DE after PCI three months was defined as standard assessing viable myocardium. Results: The changes of ejection fraction (EF), ventricular wall segmentation movement scoring index (WMSI) between pre -PCI. and post - PCI significantly correlated with numbers of viable segments (r = 0. 63) . changes of WMSI (r= - 0. 67) respectively. The sensitively (91.1%)- specificity (80%), accuracy (89.9%). positive predictive value (97. 1 %) in detecting viable myocardium by 2 - DE after PCI two weeks were higher. Conclusion: The value detecting viable myocardium by 2 -DE after PCI two weeks is higher.
