关于克山病心肌病理变化的研究已有不少报导,本材料拟就克山病心脏病理改变特点;心肌病变演变过程,以及从心肌病角度等方面对克山病的性质进行探讨。病变特点克山病心脏病变可简要归结为以下七项: 1.心脏明显的肌源性扩张、相对增重:克山病是一种心肌原发性损伤导致肌纤维张力降低的低搏出量心肌疾病,心脏增大主要是心肌反覆受损扩张的结果。它以左、右心室普遍的肌源性扩张为特点,不同于外周阻
There have been many reports about the pathological changes of Keshan disease. The material is intended to discuss the characteristics of Keshan’s pathological changes, the evolution of cardiomyopathy, and the characteristics of Keshan’s disease from the perspective of cardiomyopathy. Disease characteristics Keshan disease can be attributed to heart disease in the following seven: 1. Myocardial obvious muscle expansion, the relative weight gain: Keshan disease is a primary myocardial injury leads to decreased muscle fiber tension of the low-volume myocardial output Disease, heart enlargement is mainly the result of repeated myocardial damage and expansion. It is characterized by widespread myogenic expansion of the left and right ventricle, unlike peripheral resistance
