  "abstract": "Cardiac involvement in eosinophilic granulomatosis with polyangiitis (EGPA) strongly influences the prognosis. Takotsubo syndrome (TTS) is a reversible stress-induced cardiomyopathy that has rarely been reported in patients with EGPA. A 39-year-old woman was diagnosed with EGPA based on marked eosinophilia, systemic manifestations, and the histopathological eosinophilic infiltration of multiple organs. After remission with corticosteroids, immunosuppressants, and intravenous immunoglobulin, she suddenly developed chest pain with an ST elevation and severe left ventricular dysfunction, but normal coronary angiography findings. TTS was diagnosed. Her cardiac function recovered. However, an endomyocardial biopsy revealed advanced myocardial injury without eosinophilic infiltration. Therapy (corticosteroids, immunosuppressants, intravenous immunoglobulin, and mepolizumab) achieved long-term survival despite severe cardiac involvement.",
