自身免疫为扩张型心肌病可能的发病机制之一。其中,体液自身免疫发挥了更重要的作用,一系列的自身抗体参与扩张型心肌病的发病。炎症细胞的活化和细胞毒性作用也参与了扩张型心肌病的发病。针对扩张型心肌病的免疫发病机制,可采用免疫吸附、血浆置换、免疫抑制治疗。 Autoimmune is one of the possible pathogenesis of dilated cardiomyopathy. Among them, humoral autoimmunity play a more important role, a series of autoantibodies involved in the pathogenesis of dilated cardiomyopathy. The activation of inflammatory cells and cytotoxicity are also involved in the pathogenesis of dilated cardiomyopathy. For the pathogenesis of dilated cardiomyopathy immunosuppression, plasma exchange, immunosuppressive therapy can be used.
