Abstract: Objective To investigate the application of the ankle- brachial index(ABI) in patients with diabetic foot and analyze its influencing factors. Methods 255 patients aged (61.2 + 11.8)years with diabetic foot were evaluated by ABI and the results were compared with results of peripheral vascular Doppler ultrasound (B-ultrasound). Results ABI≤ 0.9 versus ABI＞ 0.9occurred more in age≥60 years (77.3％ vs.53.9％,P=0.036),had higher incidence of both foot ulcer (9.1％ vs.0.5％,P=0.026)and dorsalis pedis pulse weakliness (28.6％ vs.6.4％,P＜0.001)There were more arterial plaques (68.2％ vs. 42.1％,P =0.019) and occlusive (45.5％ vs.22.3％,P=0.016) in patients with ABI≤0.9 versus ABI＞0.9.The logistie regression showed that arterial plaque was positively related to ABI≤0.9 (β- 1.011,P=0.037). Conclusions ABI can be used for determining vascular stenosis in the lower limbs.Patients with age≥60 years and dorsalis pedis pulse weakened should be measured by ABI regularly.
