高脂血症是指血中胆固醇(TC)和甘油三酯(TG)升高,或高密度脂蛋白胆固醇(HDL-C)过低而导致的一种全身性疾病。现在科学的叫法是血脂异常。其中高密度脂蛋白胆固醇(HDL-C)可以将多余的胆固醇从动脉中清除,防止动脉粥样硬化形成,减少心血管事件的发生。而低密度脂蛋白胆固醇(LDL-C)含量过多时会钻入破损的动脉壁,沉积成斑块,堵塞血管,引起冠心病、中风等事件。
Hyperlipidemia refers to a systemic disease caused by an increase in blood cholesterol (TC) and triglyceride (TG), or a low HDL-C level. Now the scientific name is dyslipidemia. Among them, high-density lipoprotein cholesterol (HDL-C) can remove excess cholesterol from the arteries to prevent the formation of atherosclerosis and reduce the occurrence of cardiovascular events. However, when LDL-C is too high, it will drill into the damaged arterial wall, deposit into plaque, block the blood vessels and lead to coronary heart disease and stroke.
