摘　　要：本文旨在研究鉴别缺血性心肌病（ＩＣＭ）与扩张型心肌病（ＤＣＭ）的超声鉴别诊断方法。应用二维超声心动图对７０例ＩＣＭ及７０例ＤＣＭ的心脏形态学结构进行对比研究，优选７项指标建立鉴别ＩＣＭ与ＤＣＭ的Ｆｉｓｈｅｒ判别式。结果两组ＲＶＯＴ、ＡＯ、ＬＡ、ＲＶ、ＩＶＳｄ、ＬＶＰＷｄ和ＬＶＤｄ差别极为显著，以Ｆｉｓｈｅｒ判别式４６（ＲＶＯＴ＋ＲＶ）＋２６１ＬＡ／ＡＯ＋２８８ＬＶＤｄ／（ＩＶＳｄ＋ＬＶＰＷｄ）－３７５８＜０为ＩＣＭ，≥０与ＤＣＭ，判别总符合率达９７８％，Ｆ检验Ｐ＜００１。提示Ｆｉｓｈｅｒ判别式Ｚ＝４６（ＲＶＯＴ＋ＲＶ）＋２６１ＬＡ／ＡＯ＋２８８ＬＶＤｄ／（ＩＶＳｄ＋ＬＶＰＷｄ）－３７５８是鉴别ＩＣＭ与ＤＣＭ的简便、准确、无创的方法。The purpose of this study was to find the differential method for ICM form DCM with two dimensional echocardiography.Two dimensional echocardiography was used to analysis the cardiac morphology in 70 cases of ICM and 70 cases of DCM. Seven indinces were chosen and Fisher discriminative analysis was used to obtain the discriminant.The results showed that ICM and DCM were significantly different in these indices RVOT,AO, LA, RV, LVDd,IVSd and LVPWd.Take Fisher discriminant 4 6 (RVOT+RV)+26 1 LA/AO+28 8 LVDd(IVSd+LVPWd)-375 8 <0 as ICM,≥0 as DCM.The overall diagnostic coincidence rate was 97 8%.F test P<0 01.This result suggests that the Fisher discriminant Z=4 6 (RVOT+RV)+26 1 LA/AO+28 82 VDd/(IVSd+LVPWd) 375 8 was a simple, accuracy, noninvasine differential method for ICM from DCM.
