心肌病一般泛指主要发生在心脏肌肉层的病变。1980年世界卫生组织和国际心脏病学联合会工作组发表了关于原发性心肌病(Primary cardiomyopathy)定义和分类的报告:定义为:心肌病是原因不明的心肌疾病。分为①扩张性心肌病(Dilated caldiomyopathy);②肥厚性心肌病(Hypertrophic cardiomyopathy)和③限制性心肌病(Restrictive cardiomyopathy)。还有些未分类的心肌病(Unclassified cardiomyopathy)。此外,作者又与此等并列了特异性心肌疾病(Specific heart muscle disease),也称继发性心肌病,是已知原因或伴有其他系统病变的心肌疾病。本文限于篇幅,仅就前面三种原发性心肌病加以阐述。 Cardiomyopathy generally refers to the lesions that occur primarily in the heart muscle layer. 1980 World Health Organization and the International Federation of Cardiology team published a report on the definition and classification of primary cardiomyopathy: Defined as: Cardiomyopathy is an unexplained cardiomyopathy. Divided into ① dilated cardiomyopathy (Dilated caldiomyopathy); ② hypertrophic cardiomyopathy (Hypertrophic cardiomyopathy) and ③ restrictive cardiomyopathy (Restrictive cardiomyopathy). There are some unclassified cardiomyopathy (Unclassified cardiomyopathy). In addition, the authors rank specific heart muscle disease, also known as secondary cardiomyopathy, as a known cause or a cardiomyopathy with other systemic pathologies. This article is limited to space, only the first three to be described in primary cardiomyopathy.
