Final diagnosis:
Coronary arteritis secondary to systemic, large vessel vasculitis secondary to
probable systemic lupus erythematosus
Based on clinical, historical, and laboratory features
No biopsy was obtained

Take home points:
General internists need to recognize uncommon causes of common problems
Acute coronary syndromes can result from non-atherosclerotic luminal narrowing which has a
broad differential diagnosis
