We report a case of dilated cardiomyopathy with hyperthyroidism. A 28-year-old man was admitted because of congestive heart failure and atrial fibrillation, and was newly diagnosed as having hyperthyroidism. Despite administration of antithyroid medication, he developed recurrent congestive heart failure. An echocardiogram revealed a moderately dilated left ventricle with diffuse hypokinesis. Though his thyroid function normalized, the patient's cardiac dysfunction did not improve. Beta-blocker therapy was begun with subsequent improvement in clinical symptoms. This suggests that beta-blocker treatment may be effective in patients with atrial fibrillation associated with cardiomyopathy and hyperthyroidism.
我们报告一例扩张型心肌病合并甲状腺功能亢进症的病例。一名28岁男性因充血性心力衰竭和心房颤动入院，新诊断为甲状腺功能亢进症。尽管给予了抗甲状腺药物治疗，但他仍反复出现充血性心力衰竭。超声心动图显示左心室中度扩张，伴有弥漫性运动减弱。虽然他的甲状腺功能恢复正常，但心脏功能障碍并未改善。开始使用β受体阻滞剂治疗后，临床症状随后有所改善。这表明β受体阻滞剂治疗可能对合并心肌病和甲状腺功能亢进症的心房颤动患者有效。
