Background: Destabilization of the fibrous cap facilitates plaque rupture, thrombus formation, and myocardial infarction. Because systemic stimuli such as lipoproteins infectious agents, and autoantigens, may incite this reaction, one may wonder whether disruption mechanisms are only local or systemic and infarction is caused by an arbitrary plaque event or by a systemic, acute activity of the coronary disease. Methods and Results: Early (3 to 5 days) and late (1 month) peri-infarction coronary angiographic data in 23 patients with first infarction. Were compared with that in 23 similar patients, with angiography performed because of stable angina and repeated after, 1 month before angioplasty. Nonculprit lesion changes at the narrowest point defined progression or regression when exceeding 0.27 mm. In patients with recent infarction we found that 16 had progression, 4 had regression, 1 had both, 2 were steady (values in patients with stable angina being 2 [P
