摘要:目的:比较不同人群踝肱指数（ABI）的测量值,探讨糖尿病大血管病变的多发性及相关性 。方法: 对2007年2月至2009年5月间在本院住院的49名经冠状动脉造影和/或心肌损伤三项及心电图临床证实心肌梗死的糖尿病患者,及50名经冠状动脉造影和/或心肌损伤三项及心电图临床证实无冠脉病变的糖尿病患者,并另选取50名无糖尿病及冠心病的对照50人共149例行下肢检查,分析各组ABI的特点。结果: 三组间ABI比较均有差异,两两比较有统计学差异(Plt;0.05),且糖尿病并冠心病患者的ABI值较对照组明显下降,两组ABI值比较有统计学差异(Plt;0.01)。 结论: 糖尿病合并冠心病与糖尿病足的发病有相关一致性,ABI降低最明显。Abstract: Objective: To explore the multiplicity and correlation of macroangiopathy in type 2 diabetes,we compared the ankle brachial index(ABI) in different populations. Methods: We analyzed the ankle brachial index(ABI) of lower extremity of 149 people in our hospital from February,2007 to May, 2009:A group,49 diabetes with myocardial infarction diagnosed by coronary angiography and / or myocardial damage check and ECG.B group,50 diabetes without myocardial infarction diagnosed by the same methods. Control group, 50 people without diabetes or coronary heart disease. Results: There were significant differences among three groups, respectively (Plt;0.05). And there was decreased ankle brachial index(ABI)in diabetes with coronary heart disease compared with the control group, with significant difference(Plt;0.01). Conclusion: There was a relation between diabetes with coronary heart disease and the incidence of diabetic foot, with obvious reduction of ankle brachial index(ABI)
