Corticosteroid Therapy was Effective in Controlling Refractory Coronary Vasospasms Complicated by Hypereosinophilia

Abstract

A 48-year-old man suffered from uncontrollable coronary vasospasms, even when taking the maximum dose of vasodilators. The patient had a history of hypereosinophilia, and as the eosinophilia worsened, more frequent and intense coronary spastic angina (CSA) attacks occurred. He was treated with 20 mg/day of oral prednisolone, and the chest symptoms of CSA completely resolved thereafter. We encountered a refractory CSA patient with an allergic predisposition for which the oral administration of corticosteroids was markedly effective. Although the priority of corticosteroid therapy is not clinically high in patients with CSA, it can be effective especially in patients with an allergic background.
