The patients in this series were brought to the emergency department with noncoronary
chest pain but had electrocardiographic abnormalities and/or raised cardiac biomarkers,
consistent with a diagnosis of myocarditis. The study period was 20 months, during
which we saw 15 such patients (14 men, 1 woman). The mean (SD) age was 32 (12)
years; 6 of the patients were smokers. Most (12 patients) had no vascular risk factors, 13
patients had ST segment elevation, and 6 developed heart failure. An electrocardiogram
was recorded in 10 cases; the traces were normal in 8 cases. Cardiac catheterization,
performed in 4 patients, revealed no coronary lesions. In 3 patients the diagnosis of
myocarditis was based on nuclear magnetic resonance imaging.
