OBJECTIVES To investigate whether negative remodeling(NR) detected by intravascular ultrasound(IVUS) of the side branch ostium(SBO) would affect in-stent neointimal hyperplasia(NIH) at the one-year follow-up and the clinical outcome of target lesion failure(TLF) at the long-term follow-up for patients with left main bifurcation(LMb) lesions treated with a two-stent *** A total of 328 patients with de novo true complex LMb lesions who underwent a 2-stent strategy of percutaneous coronary intervention(PCI) treatment guided by IVUS were enrolled in this study. We divided the study into two phases. Of all the patients, 48 patients who had complete IVUS detection pre-and post-PCI and at the 1-year follow-up were enrolled in phase Ⅰ analysis, which aimed to analyze the correlation between NR and in-stent NIH at SBO at the 1-year follow-up. If the correlation was confirmed, the cutoff value of the remodeling index(RI) for predicting NIH ≥ 50% was analyzed next. The phase Ⅱ analysis focused on the incidence of TLF as the primary endpoint at the 1-to 5-year follow-up for all 328 patients by grouping based on the cutoff value of *** In phase I: according to the results of a binary logistic regression analysis and receiver operating characteristic(ROC) analysis, the RI cutoff value predicting percent NIH ≥ 50% was 0.85 based on the ROC curve analysis, with a sensitivity of 85.7%, a specificity of 88.3%, and an AUC of 0.893(0.778, 1.000), P = 0.002. In phase Ⅱ: the TLR rate(35.8% vs. 5.3%, P 2-stent strategy,and NR with RI ≤ 0.85 is linked to percent NIH area ≥ 50% at the 1-year follow-up and more TLF at the 5-year follow-up.
