2-Year Outcomes After Stenting of Lipid-Rich and Nonrich Coronary Plaques.

Background: Autopsy studies suggest that implanting stents in lipid-rich plaque (LRP) may be associated with adverse outcomes.

Objectives: The purpose of this study was to evaluate the association between LRP detected by near-infrared spectroscopy (NIRS) and clinical outcomes in patients with coronary artery disease treated with contemporary drug-eluting stents.

Methods: In this prospective, multicenter registry, NIRS was performed in patients undergoing coronary angiography and possible percutaneous coronary intervention (PCI).
