Coronary thrombosis postpartum in a young woman with Still's disease

A young woman with Still's disease sustained a small myocardial infarction 12 weeks after the delivery of a healthy male infant. This pregnancy was complicated by late onset proteinuric hypertension. Coronary angiography nine days after infarction revealed intracoronary thrombus which had resolved by 3 months with antithrombotic therapy. The angiographic appearances at 3 months suggested that a local vasculitis may have been the precipitating cause.
