Abstract

Background: Dilated cardiomyopathy (DCM) is a common cause of systolic heart failure, and is the most prevalent type of non-ischemic cardiomyopathy. Primary hyperparathyroidism (PHPT) is characterized by hypercalcemia and excessive secretion of parathyroid hormone (PTH). Generally, PHPT is asymptomatic and is incidentally identified during routine laboratory assessments.

Case summary: This case report details a 52-year-old man diagnosed with DCM and refractory hypercalcemia, who presented with clinical manifestations including dyspnea, recurrent anorexia, and abdominal distention. Laboratory investigations indicated an elevated serum PTH level, and the sestamibi scan suggested the presence of a parathyroid adenoma. Hence, the patient underwent a parathyroidectomy, which pathologically confirmed the diagnosis of a parathyroid adenoma. Postoperatively, the patient's hypercalcemia was corrected, the dimensions of the cardiac chambers were reduced, and there was a marked improvement in cardiac function.

Conclusion: Our findings emphasize the importance of PTH assessment in patients with DCM and concurrent hypercalcemia.

原发性甲状旁腺功能亢进所致可逆性扩张型心肌病1例。
背景:扩张型心肌病(DCM)是收缩期心力衰竭的常见原因,是最常见的非缺血性心肌病类型。原发性甲状旁腺功能亢进(PHPT)以高钙血症和甲状旁腺激素(PTH)分泌过多为特征。一般来说,PHPT是无症状的,在常规实验室评估中偶然发现。病例总结:本病例报告详细介绍了一名52岁男性,诊断为DCM并难治性高钙血症,临床表现为呼吸困难,复发性厌食和腹胀。实验室检查显示血清甲状旁腺激素水平升高,sestamibi扫描提示甲状旁腺瘤的存在。因此,患者接受甲状旁腺切除术,病理证实甲状旁腺瘤的诊断。术后患者高钙血症得到纠正,心室尺寸缩小,心功能明显改善。结论:我们的研究结果强调了PTH评估在DCM合并高钙血症患者中的重要性。
