摘要 冠心病发病与性激素水平和血管内皮细胞功能的关系是近年来研究的热点之一,大量动物和人体研究显示雌激素可减轻动脉粥样硬化(atherosclerosis,AS),减少女性冠心病的发病,具有心血管保护效应,适宜水平的雄激素也有抗男性AS的作用,与男性冠心病呈负相关.在AS的发生过程中,最早和最有决定性的因素之一是内皮功能紊乱[1].血管内皮是一个大的内分泌器官,分泌多种生物活性物质,对血管张力、凝血与纤溶、抗氧化系统、白细胞粘附、血管生长及脂质代谢等发挥重要调节作用.性激素可通过受体和非受体介导途径影响内皮细胞功能.本文对性激素、性激素受体调节内皮依赖性血管舒张作用及性激素替代治疗作一综述.
