Myocardial infarction - a rare complication in Henoch-Schönlein purpura.

A 29-year-old man with previous Henoch-Schonlein disease presented with multiple systemic emboli and a myocardial infarction. Subsequent investigation by angiography showed normal coronary arteries. This appears to be the first reported case of Henoch-Schonlein disease and myocardial infarction probably due to coronary vasculitis.
