Relationship between smaller calcifications and lipid-rich plaques on integrated backscatter-intravascular ultrasound.
We evaluated the relationship between coronary calcification and plaque characteristics using integrated backscatter-intravascular ultrasound (IB-IVUS), focusing on spotty calcification. Seventy-two patients with culprit plaques containing spotty calcification were evaluated. The average degree of all the spotty calcifications (averaged arc) negatively correlated with the % lipid volume (LV) on IB-IVUS. Multivariate analysis showed the averaged arc was an independent predictor of % LV. Our observations suggest that smaller plaque calcifications are associated with lipid-rich characteristics in patients with a spotty calcification pattern.
