摘要
冠状动脉扩张可定义为冠状动脉局限性或弥漫性扩张,是包括动脉粥样硬化、系统性血管炎症、结缔组织病、先天性异常、感染、中毒、局部损伤、基因异常等众多原发病引起的一种病理过程,是在各种物理、化学及生物学因子的作用下,冠状动脉中层结构和功能削弱,血管壁异常变薄形成的,其发病机制尚不清楚。本文综述近年来冠状动脉扩张发病相关因素的研究进展。
Coronary artery ectasia （CAE） is defined as a localized or diffused non-obstructive lesion of the epicardial coronary arteries with a luminal dilation exceeding 1.5 fold of the diameter of the normal adjacent arterial segment. The underlying etiology is variable and includes atherosclerosis, degenerative, congenital, inflammatory, infectious, toxic, and traumatic causes. The severity of the changes in the media correlates positively with the diameter of ectasia. The exact mechanism of its development is unknown, therefore this review is necessitated.
