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 c oronary angiogenesis at the site of an old myocardial infarction. The area of neovascularity was associated with a large apical left ventric ular thrombus. This finding suggests that growth-promoting mitogens ar e present in myocardium and thrombus and that angiogenesis occurs in s ome patients following myocardial infarction.
