Pulse Wave Velocity (PWV)


Pulse Wave is a physiological phenomenon, observable and measurable in the arterial system during blood circulation. We can observe the changes in pressure, blood flow, velocity and profile throughout the whole pulse wave. It can be used for classifying arterial elasticity.

Knowing the condition of the large, small and peripheral arteries is key to the diagnosis, treatment and prevention of cardiovascular related illness. In particular, the stiffness and augmentation of the major arteries is a strong indication of potential health problems including heart attacks, heart failure, sclerosis, and renal complications.

Age and systolic pressure strongly correlate with PWV. In fact, the most important factor contributing to increase in PWV is age because of increased arterial stiffness caused by medial calcification and loss of elasticity. The measurement of Pulse Wave Velocity is useful in the study of the effects of aging, vascular diseases, and vaso-dilating/vaso-constricting agents on arteries.

Pulse Wave Velocity measurement is a convenient method of quantifying arterial stiffness and augmentation. PWV provides invaluable insight into cardiovascular health, management of disease progression and monitoring the effects of medication, treatments, lifestyle and dietary habits. Arterial stiffness indexes (EEI, DDI and DEI) can additionally suggest to healthcare professionals to begin appropriate treatment long before the symptoms or clinical signs appear.
