Pulse Wave Velocity
Why It Matters
PWV measures arterial stiffness and is a direct indicator of cardiovascular age. Higher stiffness = greater cardiovascular risk and faster aging. Lower PWV = healthier, more flexible arteries, meaning a younger vascular system.
A 2023 study in Circulation found that PWV is a more accurate predictor of cardiovascular risk than cholesterol levels.
How To Measure It
-
Withings Body Scan
The Withings Body Scan measures Pulse Wave Velocity by detecting subtle weight variations caused by heartbeats to determine the time it takes for blood to travel from the heart to the feet. By analyzing this timing alongside user-specific data like height, the scale calculates PWV, providing insights into arterial flexibility and potential cardiovascular risks.

iHeart Internal Age Health Monitor
This fingertip device measures aortic PWV, providing insights into arterial stiffness and biological age. It also tracks blood oxygen saturation and heart rate, offering a comprehensive view of cardiovascular health.
