克山病心肌病理学研究结果认为,其病变性质类似缺血、缺氧性的心肌坏死。实验病理学研究证明,亚硝酸盐中毒可以引起动物缺氧性心肌坏死,还发现用克山病病区粮饲养的动物,这种心肌坏死的检出率及坏死面积均较用非病区粮饲养者明显增加,两组间差 Keshan disease cardiomyopathological findings that the nature of the lesion is similar to ischemic, hypoxic myocardial necrosis. Experimental pathology studies have shown that nitrite poisoning can cause hypoxemic myocardial necrosis in animals, but also found that Keshan disease area animal feeding animals, the detection rate of myocardial necrosis and necrosis area than non-ward food Feeders significantly increased, the difference between the two groups
