Acquired coronary angiogenesis after myocardial infarction.
Acquired coronary artery microvascular fistulas have been reported in only a few patients after myocardial infarction. We describe 1 patient in whom serial coronary angiography demonstrated the development of coronary angiogenesis at the site of an old myocardial infarction. The area of neovascularity was associated with a large apical left ventricular thrombus. This finding suggests that growth-promoting mitogens are present in myocardium and thrombus and that angiogenesis occurs in some patients following myocardial infarction.
