目的 了解踝臂指数(ABI)与心血管疾病各相关因素之间的关系.方法 对1084例门诊体检人群,检测空腹血糖、血清总胆固醇、三酰甘油、低密度脂蛋白胆固醇、高密度脂蛋白胆固醇、体重指数、收缩压、舒张压,并计算不同性别、不同ABI分组条件下各组的患病率.结果 男性和女性在不同ABI组中的分布不相同(χ~2=52.130,P<0.05).按ABI分组,心血管各危险因素中年龄、体重指数、收缩压、舒张压、总胆固醇、三酰甘油及空腹血糖在三组中比较,差异有统计学意义(F值分别为28.268、24.826、192.950、88.213、7.602、14.802、199.216,P<0.05).其中年龄、血压及空腹血糖随着ABI的减低而逐渐增加.随着ABI分级的增加,同时并存多个危险因素的例数逐渐增加.结论 ABI是预测心血管疾病的重要因子,有利于心血管疾病的发现和监控.

Objective To assess the relationship between ankle-brachial index (ABI) and risk factors of cardiovascular diseases.Methods A total of 1084 health check-up participants were screened for fasting plasma glucose (FBG), serum total cholesterol (TC) , triglyceride (TG), low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, body mass index (BMI), systolic blood pressure, and diastolic blood pressure.Individuals of different genders and ABI were analyzed for the mortality.Results Gender distribution in ABI groups were different (χ~2=52.130,P<0.05).Significant differences of age, BMI, systolic blood pressure, diastolic blood pressure, TC, TG, and FBG were found in three ABI groups (F value was 28.268,24.826,192.950,88.213,7.602,14.802 and 199.216, respectively; all P<0.05).Age, blood pressure, FBG, and the detective rate of risk factors of cardiovascular diseases showed an increasing trend with higher ABI.Conclusion ABI may be an important predictive factor of cardiovascular diseases.
