Eosinophilic Myocarditis: A Diagnostic Challenge and Treatment Dilemma - A Case Report

Eosinophilic myocarditis, a rare and potentially life-threatening condition, can resemble acute coronary syndrome (ACS) and presents diagnostic difficulties. We describe the case of a 32-year-old man initially admitted with ACS-like symptoms, but ultimately diagnosed with eosinophilic myocarditis. Hypereosinophilic syndrome encompasses a diverse group of blood disorders characterized by persistent, unexplained hypereosinophilia leading to tissue damage. Cardiac involvement occurs in around 20% of cases of hypereosinophilic syndrome and marks a critical phase. Our report highlights the importance of considering eosinophilic myocarditis and SHI when evaluating patients with chest pain and hypereosinophilia. It emphasizes the subtleties of diagnosis and the imperative of early identification and appropriate treatment to improve prognosis in cases of eosinophilic myocarditis. This case highlights the diverse clinical manifestations of myocarditis and the essential need for a comprehensive diagnostic approach in the presence of chest pain and hypereosinophilia.
