    146 Association of Carotid Arterial Stiffness and Coronary Plaque Characteristics: An Optical Coherence Tomography Study

    Background: The arterial stiffness predicts a higher risk of atherosclerosis. However, the association of arterial stiffness and coronary plaque morphology remains unclear. Optical coherence tomography (OCT) can reveal coronary plaque morphology in detail. In this study, we evaluated the association of carotid arterial stiffness and coronary plaque characteristics assessed by OCT. Methods: Thirty-five patients with angina pectoris were enrolled. Augmentation index (AI), stiffness parameter [beta], and pulse wave velocity (PWV) were measured by carotid ultrasound. At the coronary culprit artery, plaque characterization (lipid, or fibrous plaque), calcification, fibrous cap thickness (FCT), thin cap fibroatheroma (TCFA), and plaque rupture (PR) were ...
