目的：探讨低密度脂蛋白胆固醇(LDL-C)与高密度脂蛋白胆固醇(HDL-C)的比值(LDL-C/HDL-C)与脑梗死发生的关系。方法将本院2013年2月~2014年3月接收的136例确诊为脑梗死的患者作为试验组,对照组为110例同期检查的健康体检者,测定并比较两组LDL-C、HDL-C、总胆固醇(TC)、三酰甘油(TG)的含量,计算LDL-C/HDL-C。结果试验组的LDL-C、TC及LDL-C/HDL-C显著高于对照组,HDL-C明显低于对照组,差异有统计学意义(P<0.05),而两组间的TG水平差异无统计学意义(P>0.05)。脑梗死与LDL-C、TC及LDL-C/HDL-C呈正相关(r=0.148、0.106、0.162,P<0.05),与HDL-C呈负相关(r=-0.096,P<0.05),而与TG水平无显著性关系(P>0.05)。结论 LDL-C/HDL-C明显增高与脑梗死发生具有重要的相关性,其可以作为一项生化指标对脑梗死的发生进行预测判断,相对于单一的LDL-C或HDL-C指标具有更高的敏感性和独立性,该比值具有较高的临床价值。%Objective To observe the relationship of low density lipoprotein-cholesterol (LDL-C)/high density lipopro-tein-cholesterol (HDL-C) ratio (LDL-C/HDL-C) to acute cerebral infarction. Methods 136 patients diagnosed as cere-bral infarction in our hospital from February 2013 to March 2014 were selected as test group,and 110 healthy people examined at the same time were selected as the control group,LDL-C,HDL-C,TC,TG and LDL-C/HDL-C were detected and compared. Results The level of LDL-C,TC and LDL-C/HDL-C in test group were higher than those of control group,while the level of HDL-C was lower than that of control group,the differences were significant (P<0.05),there was no significant difference of TG between the two groups (P>0.05).Cerebral infarction was positively correlated to LDL-C, TC and LDL-C/HDL-C (r=0.148,0.106,0.162,P<0.05),was negatively correlated to HDL-C (r=-0.096,P<0.05),and had no relationship with TG (P>0.05). Conclusion The increasing of LDL-C/HDL is closely related to cerebral infarction, can be used as a biochemical indicator to predict the occurrence of cerebral infarction,compared with LDL-C or HDL-C,the ratio of LDL-C/HDL-C is more sensitive and independent,so it’s of great clinical value.
