Patients with type 2 diabetes mellitus are at an increased risk of atherosclerosis including peripheral arterial disease (PAD). The purpose of this study was to examine the possible alteration in pulse wave velocity (PWV) in lower-limb arteries among diabetic patients with PAD.


We measured brachial-ankle PWV (baPWV) using an automatic device in 101 healthy control subjects and 102 type 2 diabetic patients including those with PAD.


Diabetic patients without PAD showed a higher baPWV than the healthy control subjects. There was no significant difference in baPWV between the right and left legs in these groups. In contrast, among diabetic patients with PAD, baPWV was significantly lower in the affected legs than in the non-affected legs, and the reduction in baPWV was greater in those with lower ankle-brachial pressure index (ABI). In the patients with PAD who received percutaneous transluminal angioplasty, both baPWV and ABI were increased following successful vessel dilatation.


These results suggest that baPWV is increased in diabetic patients, whereas it is decreased in the affected legs in diabetic patients with PAD. Widening of the right-left difference in baPWV may be a novel marker of PAD.
