pulse wave velocity
Non-invasive measurement of arterial stiffness used as a marker of cardiovascular risk and subclinical atherosclerosis.
Full Definition
Pulse wave velocity (PWV) is a non-invasive diagnostic technique that measures the speed at which pressure waves travel through the arterial system, serving as a direct measure of arterial stiffness. Carotid-femoral PWV is considered the gold standard measurement and is recognized as an independent predictor of cardiovascular events. Increased PWV indicates stiffer arteries and higher cardiovascular risk, making it valuable for risk stratification in preventive cardiology. Normal values vary by age, with PWV typically increasing with advancing age and vascular disease.
Usage
Usage note: Often abbreviated as PWV in clinical documentation; specify measurement site when relevant.
