Cardiogenic shock, asthma, and hypereosinophilia.

Eosinophilic granulomatosis with polyangiitis (EGPA) (formerly Churg-Strauss) is a multisystem syndrome associating asthma, hypereosinophilia,and signs of peripheral vasculitis. We report the case of a 21-year-old man admitted for cardiogenic shock revealing a severe left and right ventricular dysfunction. Hypereosinophilia, history of asthma, and peripheral neuropathy strongly suggested the diagnosis of EGPA. Cardiac magnetic resonance imaging confirmed heart involvement with a diffuse subendocardial late gadolinium enhancement. The patient was successfully treated with systemic corticosteroids, intravenous cyclophosphamide, and inotropes. At 6-month follow-up, the patient is doing well. Cardiac involvement is rare in EGPA and often carries poor prognosis. Specific early steroid therapy may improve hemodynamic at short term, allowing postponing the need for circulatory mechanical support or heart transplantation.
