Introduction and objectives There are limited data on the usefulness of intravascular ultrasound (IVUS) for long coronary lesions treated with second-generation drug-eluting stents. We evaluated IVUS predictors of major adverse cardiovascular events (MACE) 12 months after implantation of everolimus-eluting stents for long coronary lesions. Methods A total of 804 patients who underwent both postintervention IVUS examination and long everolimus-eluting stent (≥ 28 mm in length) implantation were included from 2 randomized trials. MACE was defined as a composite of cardiac death, myocardial infarction, and target-lesion revascularization. Results MACE occurred in 24 patients (3.0%) over 12 months. On multivariable Cox regression analysis, independent IVUS predictors of MACE included the postintervention minimum lumen area (MLA) at the target lesion (HR = 0.623; 95%CI, 0.433-0.895; P = .010) and the ratio of MLA/distal reference segment lumen area (HR = 0.744; 95%CI, 0.572-0.969; P = .028). The MLA and MLA-to-distal reference segment lumen area ratio that best predicted patients with MACE from those without these events were 5.0 mm 2 and 1.0, respectively. Patients with MLA < 5.0 mm 2 or a distal reference segment lumen area had a higher risk of MACE (HR = 6.231; 95%CI, 1.859-20.891; P = .003) than those without MACE. Conclusions Patients with a postintervention IVUS-measured MLA of < 5.0 mm 2 or a distal reference segment lumen area were at risk for MACE after long everolimus-eluting stent implantation.
