目的观察踝臂指数（ABI）等危险因素与动脉粥样硬化型脑梗死的相关性。方法选取动脉粥样硬化型脑梗死患者（脑梗死组）300例及定期门诊体检者（对照组）100例，分析高血压史、糖尿病病史、吸烟史、血脂紊乱、肥胖及ABI与动脉粥样硬化型脑梗死的相关性。结果单因素分析显示高血压史、糖尿病病史、吸烟史、血脂紊乱、肥胖及ABI异常在脑梗死组和对照组间存在统计学差异（P＜0.05）；Logistic回归分析显示糖尿病病史、吸烟史、血脂紊乱、ABI异常为动脉粥样硬化型脑梗死的密切相关危险因素。结论糖尿病病史、吸烟史、血脂紊乱与动脉粥样硬化型脑梗死的发生密切相关，ABI异常可作为动脉粥样硬化型脑梗死的预测指标，临床上应重视相关危险因素的筛查与控制。

ObjectiveTo analysis the correlation between the risk factors such as ankle brachial index(ABI) and atherosclerotic cerebral infarction. Methods300 patients with atherosclerotic cerebral infarction (cerebral infarction group) and 100 health checkup people were recruited (control group) in this study. The relative analysis between history of hypertension, diabetes, smoking, dyslipidemia, obesity,ABI and atherosclerotic cerebral infarction was made. ResultsThe single factor analysis showed that the differences in histories of hypertension, diabetes, tobacco use, abnormal blood lipid profile, obesity, and abnormal anklebrachial index between the two groups were statistically significant(P＜0.05). Logistic regression analysis demonstrated that the differences in histories of diabetes, tobacco use, abnormal blood lipid profile and abnormal anklebrachial index were the risk factors for atherosclerotic cerebral infarction. ConclusionsHistory of diabetes, tobacco use, and abnormal blood lipid profile are closely related with the occurrence of atherosclerotic cerebral infarction, abnormal ABI would be a predictor for atherosclerotic cerebral infarction, and we should pay more attentions on screening and controlling such risk factors in clinic.
