Necrotizing autoimmune myopathy (NAM) is a rare inflammatory myopathy primarily affecting skeletal muscles. Cardiac involvement has been reported in immune-mediated necrotizing myopathy (IMNM), but its extent remains poorly understood. We present a unique case of a 68-year-old male with anti-signal recognition particle (SRP) antibody-positive NAM initially presenting with elevated troponin levels. Our case demonstrates cardiac involvement as the presenting feature of NAM, which is a unique feature of inflammatory myopathy.
坏死性自身免疫性肌病(NAM)是一种罕见的炎性肌病,主要累及骨骼肌。免疫介导的坏死性肌病(IMNM)中已有心脏受累的报道,但其程度仍知之甚少。我们报告了一例独特的病例,一名68岁男性,抗信号识别颗粒(SRP)抗体阳性的NAM,最初表现为肌钙蛋白水平升高。我们的病例显示心脏受累是NAM的首发特征,这是炎性肌病的一个独特特征。
