“…The distance between these two sampling sites is then divided by this time delay to arrive at the "PWV" 11 . In addition to the assessment of arterial stiffness, the automated software can also estimate the aortic root pressure (which has a direct impact on the left ventricle) by evaluating specific aspects of the arterial waveform using "pulse wave analysis" (PWA) 12,13 . Alternative techniques such as echo tracking require a great deal of technical expertise and are more time consuming than the PWV.…”

Carotid-femoral pulse wave velocity is considered the gold standard for measurements of central arterial stiffness obtained through noninvasive methods 1. Subjects are placed in the supine position and allowed to rest quietly for at least 10 min prior to the start of the exam. The proper cuff size is selected and a blood pressure is obtained using an oscillometric device. Once a resting blood pressure has been obtained, pressure waveforms are acquired from the right femoral and right common carotid arteries. The system then automatically calculates the pulse transit time between these two sites (using the carotid artery as a surrogate for the descending aorta). Body surface measurements are used to determine the distance traveled by the pulse wave between the two sampling sites. This distance is then divided by the pulse transit time resulting in the pulse wave velocity. The measurements are performed in triplicate and the average is used for analysis.
