动脉硬化指数(AI)是指血清总胆固醇(TC)减去血清高密度脂蛋白胆固醇(HDL-C)与HDL-C的比值。即TC-HCL-C/HDL-C。亦即冠心病危险因素与负性危险因素的比值。比值愈大,缺血性心脑血管病患病数愈高;反之则愈低。本文资料提示:当AI>4或血清甘油三酯(TG)/HDL-C>5时,易导致动脉粥样硬化继而发生缺血性心脑血管病。如能控制AL<3和TG/HDL-C<3时,对予防上述疾病有重要意义。
The arteriosclerosis index (AI) refers to the ratio of serum total cholesterol (TC) minus serum high density lipoprotein cholesterol (HDL-C) to HDL-C. Ie TC-HCL-C / HDL-C. That the risk of coronary heart disease and negative risk factor ratio. The greater the ratio, the higher the number of patients with ischemic cardiovascular and cerebrovascular disease; the other hand, the lower. The data suggest that: when AI> 4 or serum triglyceride (TG) / HDL-C> 5, easily lead to atherosclerosis and subsequent ischemic cardiovascular and cerebrovascular disease. If the control of AL <3 and TG / HDL-C <3, the prevention of these diseases is of great significance.
