Prevalence and Clinical Significance of Layered Plaque in Patients With Stable Angina Pectoris ― Evaluation With Histopathology and Optical Coherence Tomography ―

Background: Healed plaques are identified as a layered pattern with optical coherence tomography (OCT) imaging, but the exact relationship between healed plaques and the development of significant coronary stenosis in stable angina pectoris (SAP) is not fully understood. Methods and Results: A retrospective clinincal study investigated the OCT characteristics of culprit lesions of SAP patients (n=205), and a prospective study examined the histopathological characteristics of layered plaque in directional ...
