Cardiomyopathy is a rare but life-threatening condition in children. Myocarditis is the leading cause of dilated cardiomyopathy (DCM) and prognosis is generally poor without heart transplantation. We report a rare case of hypocalcemic DCM due to primary hypoparathyroidism in a male infant. In our patient, aggressive management of hypoparathyroidism significantly improved the manifestations of DCM. He is currently 10 years old and has no symptoms of exercise intolerance. Latest echocardiogram revealed near-normal cardiac function. Our case emphasizes that early diagnosis of this treatable cause of cardiomyopathy prevents serious sequelae.
心肌病在儿童中较为罕见但危及生命。心肌炎是扩张型心肌病（DCM）的主要病因，若不进行心脏移植，预后通常较差。我们报告一例男性婴儿因原发性甲状旁腺功能减退导致低钙血症性DCM的罕见病例。在我们的患者中，积极治疗甲状旁腺功能减退显著改善了DCM的表现。他目前10岁，没有运动不耐受的症状。最新的超声心动图显示心脏功能接近正常。我们的病例强调，早期诊断这种可治疗的心肌病病因可预防严重后遗症。
