Composition of Target Lesions by Near-Infrared Spectroscopy in Patients With Acute Coronary Syndrome Versus Stable Angina

Target lesions responsible for ACS were frequently composed of LCP; in addition, LCPs often were found in remote, nontarget areas. Both target and remote LCPs were more common in patients with ACS than in those with stable angina. Approximately one half of target lesions in stable patients were also composed of LCP.
