定义及分类原因不明的心肌疾患名为心肌病,分为三类:(1)肥厚性(或梗阻性):心肌极度肥厚,心室充盈受阻,心室腔小,并常有左室流出道梗阻,其功能障碍主要为心室肌弹性减退,从而使柔顺性降低、充盈困难,但早期时排血功能良好。(2)充血性:心脏松软而扩张,心肌仅有中度肥厚,流出道无梗阻,其功能障碍主要为严重的排血功能衰竭。(3)闭塞性:典型示例是心内膜心肌纤维化,这是一种热带疾病,心腔由于纤维组织及附壁血栓而渐趋
Defined and classified as unexplained cardiomyopathy known as cardiomyopathy, divided into three categories: (1) hypertrophic (or obstructive): extremely hypertrophic myocardium, ventricular filling blocked, small ventricular cavity, and often left ventricular outflow tract obstruction, Its dysfunction is mainly due to decreased ventricular myoelasticity, thereby reducing the flexibility, filling difficulties, but early drainage function well. (2) congestive: soft heart and expansion, myocardial hypertrophy only moderate, outflow tract obstruction, the main obstacle to dysfunction of hemorrhagic failure. (3) occlusion: A typical example is endocardial myocardial fibrosis, which is a tropical disease, the heart chamber due to fibrous tissue and mural thrombus and gradually
