Abstract-The aim of this study was to establish the relation between noninvasive Doppler ultrasound assessments of aortic compliance, based on "foot-to-foot" aortic pulse wave velocity measurements, and presumed atherosclerotic load in patients with vascular disease and/or diabetes mellitus. One hundred ten patients with vascular disease and/or diabetes mellitus (arteriopaths) underwent measurement of in vivo aortic compliance using Doppler ultrasound. Demographic data on these subjects were recorded along with details of cardiovascular risk factors and events. Aortic compliance values were compared with data from 51 age-matched healthy, asymptomatic subjects putatively free of vascular disease (controls
