We encountered a case of dystrophin-verified Becker muscular dystrophy which exhibited left heart failure as an initial symptom but no subjective muscle weakness. Severe cardiac involvement has been thought to rarely occur in the early stage of this disease, however accurate diagnosis was limited until the dystrophin diagnosis became available. This case suggests that some cases of dilated cardiomyopathy might be Becker muscular dystrophy, and that dystrophin tests should be added to the conventional investigation of patients with dilated cardiomyopathy.
我们遇到一例经肌营养不良蛋白验证的贝克型肌营养不良症，该病例最初表现为左心衰竭，但无主观肌肉无力症状。以往认为严重心脏受累在该疾病早期很少发生，然而在肌营养不良蛋白诊断可用之前，准确诊断一直受限。该病例提示，某些扩张型心肌病病例可能是贝克型肌营养不良症，并且在对扩张型心肌病患者进行常规检查时应增加肌营养不良蛋白检测。
