The Underrecognized Cardiac Manifestation of Hypereosinophilic Syndrome

Hypereosinophilic syndrome (HES) is a rare systemic disease in which cardiac manifestations are the leading cause of morbidity and mortality. HES involvement of the heart can often clinically mimic acute coronary syndrome (ACS) with the patient undergoing repeat cardiac catheterizations when no conclusive diagnosis is arrived at, and no effective treatment is suggested to alleviate recurrent symptoms of chest discomfort. Here we present an elusive case of eosinophilic myocarditis (EM) and advocate that a detailed review of history as well as obtaining all medical records be done to avoid unnecessary and repeated invasive investigations in order to provide safe, cost effective, and efficient care for our patients.
