摘要

背景:在横断面和纵向研究中，主动脉硬化与微血管结构性脑损伤和认知功能障碍有关，这可能是由于颈动脉和主动脉交界面处的波反射减少以及过度的血流脉动传递到大脑。本研究调查了年龄相关的近端主动脉硬化是否不成比例地大于颈动脉，以及近端主动脉和颈动脉之间的刚度耦合是否影响界面处的波反射。

P.23 Relationship Between Aortic Stiffness, Aortic, and Carotid Impedance with Vascular Aging in Community-Based Healthy People

Background: Stiffening of the aorta has been associated with microvascular structural brain damage and cognitive dysfunction in cross-sectional and longitudinal studies, probably due to the reduced wave reflection at the interface between carotid and aorta and transmission of excessive flow pulsatility into the brain. The present study investigated whether age-related stiffening of the proximal aorta is disproportionately greater than the carotid arteries and whether the coupling of stiffness between proximal aorta and carotid arteries affects wave reflection at the interface.
