摘要: 目的  探讨2型糖尿病合并冠心病患者血脂与冠状动脉粥样硬化程度的相关性。方法  选取2型糖尿病患者286例,根据冠状动脉造影情况分为2型糖尿病合并冠状动脉狭窄<50%(A组);2型糖尿病并冠状动脉狭窄≥50%(B组)。比较各组间一般资料及生化等指标。结果  两组糖尿病病程、糖化血红蛋白、低密度脂蛋白胆固醇(LDLC)、高密度脂蛋白胆固醇(HDLC)、LDLC/HDLC比较差异有统计学意义;多元Logistic回归分析显示:LDLC/HDLC是2型糖尿病患者发生冠状动脉粥样硬化的独立危险因素;ROC曲线结果显示:LDLC/HDLC最佳临界点为2.53时敏感度为77.6%,特异度为82.3%。结论  LDLC/HDLC在预测2型糖尿病患者发生冠状动脉病变优于单纯LDLC和HDLC。

Abstract: Objective  To investigate the correlation between blood lipids and the degree of coronary atherosclerosis in patients with type 2 diabetes and coronary heart disease. Methods  According to the status of coronary angiography,  a total of 286 patients with type 2 diabetes were divided into two groups: type 2 diabetes with coronary artery stenosis <50%(Group A),  and type 2 diabetes with coronary artery stenosis≥50% (Group B). General information and biochemical indicators between two groups were compared. Results  There was significant difference between two groups in the course of diabetes,  hemoglobin A1c (HbA1c),  lowdensity lipoprotein cholesterol(LDLC),  highdensity lipoprotein cholesterol (HDLC), and LDLC/HDLC(P<0.05). Logistic multivariate regression analysis showed that: LDLC/HDLC was an independent risk factor for coronary atherosclerosis in patients with type 2 diabetes. The ROC curve results showed that the optimal critical point of LDLC/HDLC was 2.53,  at this time the sensitivity was 77.6%  and the specificity was 82.3%.Conclusion  LDLC/HDLC is better than LDLC and HDLC in predicting coronary artery disease in patients with type 2 diabetes.
