类风湿性关节炎是以关节炎为主的慢性全身性免疫性疾病,除关节病变外,全身各器官均可受累。目前对类风湿性关节炎的关节外损害报道日渐增多,心血管系统损害的发生率高,死亡率亦随之增高。近代 Lebowitz 等的研究揭示了类风湿性关节炎患者的心脏损害,相继有许多类似报道,但这种损害仅于病理检查时发现,而临床仍无特征性诊断依据。近10年来应用超声心动图(UCG)检查,使类风湿性心脏损害在临床上被认识。类风湿性心脏病的概念 Rheumatoid arthritis is a chronic systemic autoimmune disease dominated by arthritis. Apart from joint disease, all organs of the body can be involved. At present, the reports of extra-articular damage to rheumatoid arthritis are increasing, the incidence of cardiovascular system damage is high, and the mortality rate also increases. Recent studies by Lebowitz et al. Have revealed cardiac damage in patients with rheumatoid arthritis, many of which have been reported in succession, but such lesions have been found only during pathological examination and are still not clinically characterized. In the past 10 years, the application of echocardiography (UCG) examination, so that rheumatic heart damage is clinically recognized. Rheumatic heart disease concept
