The postcardiac injury syndrome following percutaneous transluminal coronary angioplasty.

A 57-year-old man, who had suffered an anterior Q-wave myocardial infarction complicated with typical post-cardiac injury syndrome (PCIS) 9 years earlier, underwent percutaneous transluminal coronary angioplasty (PTCA) without any immediate clinical, laboratory, or radiological signs of complications. After 4 days he recognized the recurrence of the earlier symptoms of PCIS. The diagnosis was supported by slight fever, elevated inflammatory parameters, and improvement when oral corticosteroids were given. The observations suggest that milder cardiac injury than previously considered, that is, without demonstrated structural damage to pericardium or myocardium, may precipitate PCIS in predisposed individuals. The case adds a differential diagnosis to chest pain and malaise following PTCA.
