  • Abstract
  • Look Inside

A 53-year-old male was admitted to the hospital due to electrocardiographic ST-segment elevation in V1-4 with ST-segment depression in the inferior leads, which suggested acute myocardial infarction. He had a cough and a slight fever without chest pain. Serum creatine kinase and its myocardial band were slightly elevated but creatine kinase value did not exceed twice the normal upper limit. Emergent coronary arteriography (CAG) revealed intact coronary arteries.

The CAG in a chronic stage again revealed intact coronary arteries.
