Apical myocardial infarction with bizarre coronary images mimicking left ventricular apical ballooning syndrome: a case report.

Introduction: Although several etiopathogenetic mechanisms have been proposed, the causes of left ventricular apical ballooning syndrome are still controversial.

Case Presentation: A 51-year-old Japanese woman consulted the emergency room complaining of the sudden onset of anterior chest pain while shopping. We initially suspected her disease as left ventricular apical ballooning syndrome based on her clinical background and laboratory examinations.

Corticosteroid therapy was effective in controlling refractory coronary vasospasms complicated by hypereosinophilia.

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.
