甲状腺功能亢进性心脏病

甲状腺功能亢进（甲亢）性心脏病是由于甲亢时过量的甲状腺激素对心脏的直接毒性作用或间接影响而引起的一系列心血管系统症状和体征的一种内分泌代谢紊乱性心脏病。它的发生与患者的年龄、病程、治疗是否规范、低钾、感染和妊娠等因素有关。甲亢性心脏病目前尚无统一的诊断标准，一般认为，甲亢伴心律失常、心脏扩大、心力衰竭常为其必备症状和体征，但需除外其他原因引起的心脏疾患，以减少误诊和漏诊。而且多数甲亢性心脏病可随甲亢的治愈或有效控制而治愈或好转，但也可继续存在，甚至成为永久性后遗症。

Hyperthyroid heart disease

Hyperthyroid heart disease is a series of signs and symptoms of cardiovascular system re- suhing from metabolic disorder,which caused by the direct or indirect toxic actions of excessive thyroid hor-mones. Its pathogenesis is associated with age of patient, course of disease, regular therapy or not,hypopotas-saemia, infection, pregnancy and so on. There is no unified diagnostic standard at present. Heart dilatation, arrhythmia and/or heart failure are thought necessary signs and symptoms. But in order to decrease misdiagnosis and missed diagnosis ,we should exclude heart diseases caused by other reasons. The majority of hyperthy- roid heart disease are often curative or improved companied by the controll of hyperthyroidism, although some patients will hold it all the time, even become permanent sequelae.
