健康人抽血测定血清总胆固醇含量时,也应该测定血清高密度脂蛋白(HDL)含量,这是在Bethesda的国家健康研究所专门研究小组提出的建议。高密度脂蛋白经常被称为“有益的胆固醇”,它是一种从血液中清除胆固醇和有损害倾向的脂肪物质的运输分子。科学家们证实HDL含量低于正常值会增加患冠状动脉性疾病的危险,这是由于脂肪物质沉积于冠状动脉造成心脏病发作。上周这个专门研究小组宣称,血清总胆固醇含量测定尚不能充分评价一个人是否易患心脏病。国家胆固醇研究机构认为血清胆固醇含量的理想范围应低于5.2 mmol/L(200 mg/dl)。但是,当对这方面作大量的回顾性研究时,胆固醇专门研究小组认为即使具有理想胆固醇含量的人,如果其血清HDL降到0.91mmol/L(35mg/dl)以下时,他们仍然易患冠状动脉
Determination of serum high-density lipoprotein (HDL) levels should also be used when determining blood levels of total cholesterol in healthy people, as suggested by a panel of Bethesda’s National Institutes of Health. High-density lipoprotein, often referred to as “beneficial cholesterol,” is a transporter that clears cholesterol and has a propensity for fatty substances from the bloodstream. Scientists have shown that lower than normal HDL levels increase the risk of coronary artery disease because of the deposition of fatty substances in the coronary arteries that cause heart attacks. Last week this special group claimed that the determination of serum total cholesterol has not been able to fully assess whether a person is susceptible to heart disease. National Cholesterol Research Institute that the ideal range of serum cholesterol should be less than 5.2 mmol / L (200 mg / dl). However, when making a large number of retrospective studies in this area, the cholesterol panel believes that even those with the desired cholesterol levels are still predisposed to coronary disease if their serum HDL drops below 0.91 mmol / L (35 mg / dl) artery
