A 52-year-old woman presenting with shortness of breath and having no related past medical history was diagnosed with takotsubo cardiomyopathy. However, she revealed respiratory failure atypical with takotsubo cardiomyopathy. We diagnosed myasthenia gravis with myasthenic crisis by acetylcholine receptor-binding antibody titer with mediastinal tumor. Physical or emotional stress is well known to trigger the onset of takotsubo cardiomyopathy. Similarly, myasthenia crisis is also triggered by stress. Here, we report a case of simultaneous occurrence of takotsubo cardiomyopathy and myasthenia crisis.
一名52岁女性，因气短就诊，既往无相关病史，被诊断为应激性心肌病。然而，她出现了与应激性心肌病不符的呼吸衰竭。我们通过乙酰胆碱受体结合抗体滴度及纵隔肿瘤诊断为重症肌无力伴肌无力危象。众所周知，身体或情绪应激会引发应激性心肌病。同样，肌无力危象也由应激引发。在此，我们报告一例应激性心肌病与肌无力危象同时发生的病例。
