Risk Factors Associated With Diabetic Foot Ulcers and Its Relationship With ABI and Brachial-Ankle Pulse Wave Velocity.

ABSTRACT

To evaluate the risk factors associated with diabetic foot ulcers (DFUs) and to analyze the relationship of DFUs and the value of Ankle-Brachial Index (ABI) and brachial-ankle pulse wave velocity (baPWV). In this retrospective study, the risk factors associated with DFUs were analyzed, and the value of ABI and baPWV were measured to find its relationship with DFUs. Binary logistic regression analysis indicated that neuropathy and ABI were independent risk factors for DFUs. The patients were divided into 2 groups according to the value of ABI. For patients with DFUs, the value of baPWV decreased with the decrease of ABI. In normal or high ABI group, about a quarter of patients who suffered from DFUs had a higher value of baPWV than the others without DFUs. The pathogenesis of DFUs was multifactorial. Regarding the occurrence and development of foot ulcers, the action of vascular occlusion was more important than vascular sclerosis. ABI measurements should be taken more seriously in patients with DFUs. baPWV should be taken with care in the follow-up of the patients without DFUs. However, in patients with a normal value of ABI, the degree of vascular sclerosis of patients with DFUs may be greater than those without ulceration.
