Compliance in largely central arteries of patients with peripheral vascular disease (PVD) has been reported to be reduced. However, the arterial tree is an inhomogeneous system, and there remains uncertainty about whether the peripheral arteries (e.g. the medium-sized muscular radial artery) undergo a similar change to the central arteries. The aim of this study was to investigate the radial artery elasticity in 19 patients with PVD compared with 18 normal subjects of comparable age and sex. Using a noninvasive high-resolution echo-tracking device coupled to a photoplethysmograph (Finapres system) allowing simultaneous arterial diameter and finger blood pressure monitoring, we measured the radial artery compliance by determining the diameter-pressure, compliance-pressure and distensibility-pressure curves. The results showed that the diameter of the radial artery was similar in the two groups, but that the compliance and distensibility were not further reduced in patients with PVD than in the normal controls at 100 mmHg and for a common blood pressure range. The present studies demonstrate that in patients with PVD the radial arterial compliance is not reduced, which indicates that the change in arterial elasticity is not identical. The potential mechanisms involved in this change in radial artery compliance are discussed.
