Objectives The aortic augmentation index (AI) and aortic pulse wave velocity (PWV) are
known to be indicators of arterial stiffness. However, it is not clear whether aortic AI and PWV
reflect aortic stiffness in similar ways. We investigated the relationship between aortic AI and
PWV by measuring them directly using a catheter technique. Design and methods Forty-one
patients, aged 34–79 years, were studied during diagnostic cardiac catheterization. Aortic
pressures were measured using a catheter-tip manometer at two points, one in the …
