Myocarditis--the first symptom of adult Still's disease
Myocardial involvement during the course of adult Still's disease is very rare. We present a case of a 34-year-old man admitted with fever, tachycardia, weakness and chest discomfort. The electrocardiogram showed non-specific diffuse ST-T changes, troponin level was slightly elevated and echocardiography did not reveal any abnormalities. After ruling out other relevant diseases, the adult Still's disease was diagnosed.
