中文摘要：

目的探讨脑卒中高危人群FBG/HDL-C比值与代谢综合征（MetS）的相关性。方法检测405例脑卒中高危人群的血糖、血脂等相关指标,计算FBG/HDL-C比值,分析FBG/HDL-C比值与MetS的相关性。结果根据FBG/HDL-C比值,405例患者分为Ⅰ组（〈3.92）、Ⅱ组（3.92-4.77）和Ⅲ组（〉4.77）,每组135例。三组BMI、FBG、HDL-C和MetS患病率差异均有统计学意义（P〈0.05）。ROC曲线分析,FBG/HDL-C比值诊断脑卒中高危人群MetS的ROC曲线下面积为0.805[95%CI（0.763-0.843）,P〈0.01],取FBG/HDL-C比值4.406为最佳诊断界值,其诊断脑卒中高危人群MetS的灵敏度为83.9%,特异度为70.5%。结论脑卒中高危人群FBG/HDL-C比值与MetS诊断相关。FBG/HDL-C比值有望成为脑卒中高危人群MetS的诊断指标之一。

英文摘要：

Objective To investigate the correlation between the ratio of fasting blood glucose to high density lipoprotein cholesterol（FBG/HDL-C ratio）and metabolic syndrome（MetS）in the people at high risk of stroke.Methods The indicators related to blood glucose and lipids were detected in 405 cases at high risk of stroke.FBG/HDL-C ratio was calculated.The correlation between FBG/HDL-C ratio and MetS was analyzed.Results According to the FBG/HDL-C ratio,405 cases at high risk of stroke were divided into three groups of A（〈3.92）,B（3.92-4.77）and C（〉4.77）with 135 cases each.The differences in body mass index（BMI）,FBG,HDL-C,and the morbidity of MetS were significant among three groups（P〈0.05）. The receiver operating characteristic（ROC）analysis showed that the area under the ROC curve for FBG/HDL-C ratio to diagnose MetS was 0.805[95%CI（0.763-0.843）,P〈0.01],taking 4.406 as a cutoff value,the sensitivity and specificity for FBG/HDL-C ratio to diagnose MetS were 83.9% and 70.5%,respectively.Conclusion FBG/HDL-C ratio is correlated to MetS in the people at high risk of stroke and hopefully becomes one of the indicators in the diagnosis of MetS.
