Cardiac manifestations of idiopathic hypereosinophilic syndrome

BACK GROUND: The aim of our study is to describe the more common cardiac manifestations of idiopathic hypereosinophilic syndrome representing the major cause of mortality. MAIN POINTS: Current therapy consists of corticosteroid, hydroxyurea and interferon alpha. Recent publications confirm the activity of imatinib mesylate, a selective tyrosine kinase inhibitor, in patients with idiopathic hypereosinophilic syndrome. In cases with marked valvular compromise or with endomyocardial thrombosis or fibrosis, cardiac surgery can provide substantial benefits. PERSPECTIVES: A better understanding of the pathophysiology of this syndrome could lead to the development of new therapeutic agents.
