We present the case of a 50-year-old man presenting with new heart failure symptoms. He had no evidence of any ischaemic cardiomyopathy, however, further cardiac imaging showed a left ventricular non-compaction cardiomyopathy. He was noted to have muscular weakness and an exhaustive search for associated comorbidities yielded a diagnosis of Becker muscular dystrophy. In this report, we review the pathophysiology, comorbidities and diagnostic workup in patients presenting with left ventricular non-compaction in the context of dystrophinopathy. Ultimately, we suggest the consideration of rare cardiomyopathies in all patients presenting with neuromuscular syndromes and vice versa.
我们报告了一例 50 岁男性出现新的心衰症状。他没有任何缺血性心肌病的证据，但进一步的心脏成像显示左心室致密化不全性心肌病。他被发现有肌肉无力，对相关合并症进行详尽的搜索后诊断为 Becker 型肌营养不良症。在本报告中，我们回顾了在肌营养不良症背景下，出现左心室致密化不全的患者的病理生理学、合并症和诊断检查。最终，我们建议所有出现神经肌肉综合征的患者都考虑罕见的心肌病，反之亦然。
