Figure 11 Relationship Between Age and Ascending Aortic Pressure Wave Augmentation

Relationship between age and ascending aortic pressure wave augmentation (A) calculated with SphygmoCor from radial artery tracings in 1,600 patients attending a cardiovascular outpatient clinic, together with values for a group of 4,001 normal U.K. men (red thin line) and women (red dashed line) from McEniery et al. (74) and 534 normal European subjects (men and women combined, thick line) from Wojciechowska et al. (75). (Inset, upper left) Method of calculating aortic pressure augmentation. AIx = augmentation index; PP = pulse pressure.
