2、肌梗死患者行AutoEF重复性研究。结果7O例研究对象中,68例(97%)完成AutoEF测量,其中43例(63%)为完全自动,25例(37%)需手动校正;AutoEF测量时间为(59.28~13.13)s,少于Simpson’s法[(96.67~8.26)s],差异有统计学意义(P3、偏低;在观察者自身和观察者间,AutoEF法测定心肌梗死患者LVEF均有良好的一致性。结论AutoEF法能够简便、及时和快速测量左室容积和LVEF,且经验依赖性较小。关键词超声心动描记术;心肌梗死;心室功能,左;斑点追踪成像[中图法分类号】R542.22;R540.45[文献标识码]AFeasibilityofassessingleftventricularglobalsystolicfunctioninpatientswithmyocardialinfarctionusinganovelautomatedejectionfractionYuJunli,GaoRuifeng,ZhangYu4、anyuan,HeHui,CuiYanhua,ZhangQuanbinDepartmentofUhrasound,GenerMHospitalofTaigang,ShanxiMedicalUniversity,Taiyuan030003,ChinaABSTRACTObjectiveToexplorethefeasibilityandreproducibilityofassessingleftventricular(LV)globalsystolicfunctionofthepatientswithmyocardialinfarctionbyanovelautomatedejectionfr5、action(AutoEF).MethodsThirty—fivepatientswithmyocardialinfarctionand35healthysubjectswereincluded.LVenddiastolicvolume(LVEDV),LVendsystolicvolume(LVESV)andLVejectionfraction(LVEF)measuredbyAutoEF.theresultswerecomparedwitllthoseofbiplaneSimpson’Smethod.Thecorrelationbetweentwomethodswasobserved.206、patien~withmyocardialinfarctionwererandomlyselectedtostudythereproducibility.ResultsAutoEFwasperformedin68patients(97%),43(63%)ofthemwerecompletelyautomatedand25(37%)requiredmanualediting.AutomaticmeasurementrequiredlesstimethanbiplaneSimpson’Smethod【(59.28~13.13sVS.(96.67~8.26)s,P<0.01].Theseries7、LVparametersofthe68cases,whichincludingmyocardialinfarctiongroupandhealthycontrolgrouphadstrongcorrelationinLVEDV,LVESVandLVEFbetweentwomethods(rwere0.947,0.971,0.974,respectively,P
