Measurement of vascular remodeling.Vascular remodeling was measured on longitudinal image. Positive vascular remodeling is noted at site of plaque (arrowheads). Degree of vascular remodeling (%) = (A1-A0)/A0 × 100 (A1 = maximum outer diameter of coronary artery at site of plaque, A0 = maximum outer diameter of coronary artery just proximal to plaque).
