摘　　要：目的　观察一组经正电子发射断层扫描技术 (PET)判别心肌功能状态患者的常规超声资料和病史 ,了解心肌梗死区无存活心肌的患者和有存活心肌患者在常规超声检查中的差异情况。方法　 35名冠心病患者经PET检查 ,根据存活心肌的有无进行分组 :Ⅰ组 ,梗死区有存活心肌 ;Ⅱ组 ,梗死区无存活心肌。对比常规超声检查项目参数在无存活心肌组和有存活心肌组的差异 ,结合病史等临床资料进行分析。结果　所有的常规超声检查参数中 ,Ⅱ组患者的左房 (LA )内径明显大于Ⅰ组患者 [( 4 0 .0 8± 5 .32 )mmvs ( 36 .17± 6 .2 4)mm ,P <0 .0 5 ] ,Ⅱ组患者的病程较Ⅰ组短。结论　左房前后径是心肌梗死后是否存在存活心肌的重要的相关因素。梗死区无存活心肌的患者左房较小 ,病史短 ,与代偿不充分有关 ;而梗死区存在存活心肌的患者左房较大 。Objective To evaluate the difference of clinical materials and routine echocardiographic parameters between patients with and without viable myocardium in the infarcted areas confirmed by positron emission tomography (PET).Methods Thirty five patients with coronary artery disease were divided into two groups according to the status of myocardial viability shown by PET. Echocardiography was performed in a week after or before examination of PET.Results The history was significantly longer and no LV aneurysm happened in group Ⅰ(with viable myocardium in the infarcted area).However,there were no significant differences in all echocardiographic parameters between the two groups except the inner diameter of the left atrium [LA diameter: groupⅠ ( 40.08 ± 5.32 )mm vs group Ⅱ ( 36.17 ± 6.24 )mm,P< 0.05 ],the diameter of LV was significantly higher in groupⅠ.Conclusions Whether or not LA performed a sufficient compensation is of vital importance in the existence of viable myocardium in the infarcted area. There is larger LA and longer history in patients with viable myocardium in the infarcted area.
