Why the study?
Does the pattern of coronary calcification and plaque morphology on IVUS differ between patients with acute myocardial infarction, unstable angina, and stable angina?

Spotty calcification on IVUS, along with fibrofatty plaque and positive remodeling, is a key morphological feature identifying vulnerable culprit plaques in acute myocardial infarction.
No takes yet. Share an insight, caveat, or question.
May flag vulnerable AMI plaques on IVUS; hypothesis-generating, requires prospective validation before clinical use.
Ehara et al. (2004) studied this question.
