高密度脂蛋白(HDL)是血浆蛋白中的一部分。除具有促进血浆蛋白代谢之外,还有摄取血液中的胆固醇运送到肝脏里进行分解排出的作用。故认为HDL的变化对动脉粥样硬化有着直接的影响。不仅如此,大量的研究还表明,HDL的水平与冠心病、脑血管病病人的发病也存在着十分密切的联系,冠心病人的HDL的平均水平要比健康者的平均水平低,脑力劳动者的HDL水平比体力劳动者的HDL水平较高。也有人报导,HDL的浓度每低于正常 High-density lipoprotein (HDL) is a part of plasma proteins. In addition to the promotion of plasma protein metabolism, but also the intake of cholesterol in the blood transported to the liver decomposition decomposition role. Therefore, the change of HDL has a direct impact on atherosclerosis. Not only that, a large number of studies also show that the level of HDL and coronary heart disease, the incidence of cerebrovascular disease is also very closely linked to the average level of HDL in patients with coronary heart disease is lower than the average level of healthy, mental workers HDL levels higher than manual workers HDL. It has also been reported that the concentration of HDL is lower than normal
