Different angiographic findings between acute MI and stable angina suggest distinct pathophysiological factors, such as thrombosis propensity, drive these syndromes.
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.
Bogaty et al. (Tue,) studied this question.
