Despite the benefits of successful percutaneous coronary interventions (PCIs) for @entity432 ( @entity432 ) lesions, PCIs of @entity432 lesions still carry a high rate of adverse events, including in-stent restenosis (ISR). Because previous reports have not specifically investigated the intravascular ultrasound (IVUS) predictors of ISR in @entity432 lesions, we focused on these predictors. We included 126 @entity1 who underwent successful PCIs, using drug-eluting stents, and post-PCI IVUS of @entity432 lesions. @entity1 and lesion characteristics were analyzed to elucidate the ISR predictors. In each lesion, an average of 1.7    0.7 (mean length, 46.4    20.3 mm) stents were used. At 9 months follow-up, 14 (11%) @entity1 demonstrated ISR, and 8 (6.3%) underwent @entity75 revascularization. Multivariate logistic regression analysis showed that the independent predictors of ISR were the post-PCI @entity5562 ( @entity5562 ) and the stent expansion ratio (SER; minimal stent cross-sectional area (CSA) over the nominal CSA of the implanted stent), measured using quantitative coronary angiography (QCA) and IVUS, respectively. A receiver operating characteristic analysis indicated that the @entity3987 and SER cut-off values for predicting ISR were 2.4 mm (area under the curve [AUC], 0.762; 95% confidence interval (CI), 0.639-0.885) and 70% (AUC, 0.714; 95% CI, 0.577-0.852), respectively. Lesions with post-PCI @entity5562 and SER values less than these threshold values were at a higher risk of ISR, with an odds ratio of 23.3 (95% CI, 2.74-198.08), compared with lesions having larger @entity5562 and SER values. Thus, the potential predictors of ISR, after PCI of @entity432 lesions, are the post-PCI @entity5562 and SER values. The ISR rate was highest in lesions with a post-PCI @entity5562  <=2.4 mm and an SER  <=70%.
