What are the coronary angioscopic findings in the infarct-related vessel within 1 month of acute myocardial infarction?
Coronary angioscopy reveals that infarct-related lesions take more than 1 month to heal and frequently contain unstable yellow plaques with adherent thrombus, which may explain their higher propensity to occlude.
These results suggest that healing of the infarct-related lesion requires more than 1 month and that an "unstable" yellow plaque with adherent thrombus is common during that period. This finding may partly explain the unique behavior of recent infarct-related lesions, which are more prone to occlude than other lesions.
Belle et al. (Tue,) studied this question.
