Abstract

Uncontrolled hypereosinophilic syndrome is frequently associated with cardiovascular consequences that cause significant morbidity and mortality. The present article reports on a patient with hypereosinophilic syndrome in whom recurrent, recalcitrant coronary artery spasm and associated cardiac arrest were the predominant cardiac manifestations. No valvular abnormalities, evidence of mural thrombi or other cardiac findings commonly associated with hypereosinophilic syndrome were detected, and cardiac function remained normal. The serum tryptase level was normal, cysteine-rich hydrophobic domain 2 (CHIC2) deletion analysis of bone marrow cells was negative and no evidence of mastocytosis or other hematological disorder was found in the bone marrow. To allow for the reduction of prednisone, interferon-alpha-2b was added to the patient's program, but caused aggravation of chest pain and was discontinued. However, a combination of reduced prednisone dosage, imatinib mesylate and hydroxyurea successfully controlled the eosinophilia, and thereafter, episodes of coronary artery spasm did not recur. The clinical features of the present case suggest that, in some patients, hypereosinophilia may manifest as resistant coronary artery spasm and that aggressive control of eosinophilia is necessary.
