摘　　要：目的 探讨超声对扩张性心肌病（DCM）与缺血性心肌病（ICM）鉴别诊断的价值.方法 应用二维彩色多普勒（2D-CDFI）观察80例DCM患者、80例ICM患者及80例正常人的心脏形态学血流动力学及心功能三个方面的改变.结果 （1）DCM组心脏呈普遍增大,室壁活动弥漫性减弱,ICM组心脏呈局限性增大,室壁活动阶段性减弱.（2）DCM组瓣膜返流发生率较ICM组高,且返流程度较ICM组重.（3）DCM组主要以收缩功能低下为主,ICM组则以舒张功能障碍为主.结论 超声2D-CDFI是鉴别DCM与ICM的首选方法.Objective To explore the differential diagnosis value of ultrasonographie for DCM and ICM. Methods DCM lacks specificity ehiniaeally, easy to be mixed with ICM,Noninvasive diagnostic approaches to distinguish DCM from ICM with ultrasonographie were made 80 eases of DCM , 80 eases of TCM and80 normalopers ans referring toeardiae morphology hemodynamies and functions. Results （ 1 ） In morphdogy, the heart of DCM patients is mostly enlarge ,the ventrieular wyall motion decreased widely. The ICM heart is limitedly enlarged, the ventrieular wall motion deereaesd segmentally. （2）In hemodynamies,the incidence of valvular regurgitut ion in DCM is much higher than that in ICM, the degree of valular regurgitation in DCM is more severe than that in ICM. （ 3 ） In cardiac functions, DCM is marked by lower ventrieular systolic function,while ICM is mainly characterized by ventrieular diasyolie dysfunction in early stage. Conclusion Uhrasonographie would be the first method for differential diagnosis of DCM and ICM.
