Balcer B, et al. - Patients with acute myocardial infarction were examined to assess the association of pericoronary adipose tissue (PCAT) volume and attenuation with culprit lesions in the underlying coronary segment. Findings suggested an inverse correlation between CT-derived pericoronary fat volume and attenuation. Increased pericoronary fat volume was observed around coronary segments with culprit lesions. No differences in CT-derived pericoronary fat attenuation was noted around culprit lesions. Pericoronary fat volume but not attenuation could be predictive of acute coronary syndromes. Findings thereby indicated PCAT volume to have strong and independent association with culprit lesions in the underlying coronary segments in patients with acute myocardial infarction.
