1 Αυγ 2002 · This review analyses methods and devices used worldwide to evaluate the arterial stiffness. Three main methodologies are based upon analysis of pulse transit time, of wave contour of the arterial pulse, and of direct measurement of arterial geometry and pressure, corresponding to regional, systemic and local determination of stiffness.
Increased arterial stiffness affects the capacity of the aorta and elastic arteries to adapt to pressure variations during the cardiac cycle. The main markers of arterial stiffness are pulse wave velocity (PWV), augmentation index (AIx) and central aortic pressure. They can be measured noninvasively.
Arterial stiffness can be assessed noninvasively using the following methods: 1) relating change in vessel size (diameter or area) to distending pressure, 2) estimation of pulse wave velocity, 3) pulse waveform analysis.
