This is a multi-center, investigator initiated study that will prospectively examine treatment strategies and outcomes of patients who underwent clinically-indicated Near Infrared Spectroscopy (NIRS). The information collected will be used to determine the frequency of NIRS imaging performed at the participating sites and to examine the clinical outcomes of the NIRS-detected Lipid Core Plaques (LCPs).

Incidence of major adverse cardiac events
The primary endpoint for both hypotheses is the incidence of major adverse cardiac events. Major adverse cardiac events include the following: * cardiac death * cardiac arrest * acute coronary syndrome * stent thrombosis, repeat coronary angiography * coronary revascularization (either by percutaneous coronary intervention or coronary artery bypass graft surgery). * rehospitalization for progressive angina, attributed to a non-culprit lesion secondary to significant fixed, non-reversible (not-spasm related) lesion progression of more than 20% from the baseline study (confirmed by either serial angiography or by necropsy). Events will be classified as events occurring at the site of stent implantation and events occurring at previously untreated lesions. Moreover, analyses will be performed on a per patient and per LCP basis.
Time frame: 1 to 15 years following clinically indicated Near InfraRed Spectroscopy imaging
