Comparison of coronary angiographic findings in acute and chronic first presentation of ischemic heart disease.

Abstract

These very different angiographic findings suggest that unheralded acute myocardial infarction and uncomplicated chronic stable angina do not occur randomly on a common atherosclerotic background but rather that additional factors, such as a varying propensity to thrombosis, may predispose to one or the other of these two clinical syndromes.
