摘要 目的探讨老年心肌致密化不全与老年扩张型心肌病的超声心动图特征和临床特征。方法通过中国期刊全文数据库检索出2000年1月至2005年7月国内发表且年龄≥60岁的心肌致密化不全(NVM)文献报道共9例,结合同期本院收治年龄≥60岁的NVM患者3例,扩张型心肌病(DCM)23例的超声心动图和临床特征进行回顾性分析。结果(1)NVM组超声心动图可见受累心腔内异常隆突、粗大的肌小梁和其间深陷的隐窝影像,以左房室腔扩大为主,心肌致密化不全层与致密层厚度比>2;DCM组超声心动图可见心室壁变薄及动度弥漫性减弱,右房室内径扩大;(2)DCM组多瓣膜返流发生率较高且程度较重,NVM组多为单瓣膜返流且程度较轻,NVM组室壁节段性运动异常发生率较高(P<0.01);(3)NVM组和DCM组临床均有程度不同的左心功能不全、心律失常等表现,缺乏特征性。结论NVM具有特征性超声心动图改变,可区别于DCM。超声心动图是诊断NVM的重要手段。
