Figure 3 Change in Aortic PWV With Age

Change in aortic pulse wave velocity (PWV) with age in a group of 480 normal subjects in a northern urban Chinese community with low prevalence of atherosclerosis (15). The regression line for this group (top) was significantly different from that of another normal Chinese community in Guandong (bottom) with similarly low prevalence of atherosclerosis but low salt intake and lower prevalence of hypertension (16).
