Figure 2 (A) Negative remodeling (remodeling index [RI] <0.9) was seen in 60% of the focal in-stent restenosis (ISR) lesions and, in contrast, in only 26% of the diffuse ISR lesions. Conversely, positive remodeling (RI >1.1) was seen in only 16% of the focal ISR lesions and in 30% of the diffuse ISR lesions (p = 0.0456 by the chi-square test). (B) The baseline RI in the diffuse ISR group was significantly larger than that in the focal ISR group (1.03 ± 0.18 vs. 0.88 ± 0.24, p = 0.0159). IR = intermediate remodeling; NR = negative remodeling; PR = positive remodeling.
