What is the Meaning of Pulse Wave Velocity?

Pulse Wave Velocity (PWV) is a non-invasive, quantitative measure of arterial stiffness, representing the speed at which the arterial pressure wave travels between two points in the circulatory system. A higher PWV indicates greater arterial rigidity and is a robust, independent biomarker for increased cardiovascular risk, including hypertension and stroke. It provides a direct assessment of vascular wellness and the physical state of the large arteries.

What is the Origin of Pulse Wave Velocity?

This is a biophysical measurement rooted in fluid dynamics and vascular physiology. The concept emerged from the need for a simple, reproducible clinical metric to assess arterial health beyond blood pressure alone. The measurement has become a key parameter in advanced cardiovascular risk stratification, especially in populations with metabolic and endocrine disorders.

What is the Mechanism of Pulse Wave Velocity?

The velocity of the pulse wave is inversely proportional to the elasticity of the arterial wall. In a healthy, compliant artery, the wave travels slowly; however, when the arterial wall stiffens due to age, hypertension, or chronic inflammation, the wave travels much faster. This stiffening is often due to changes in the extracellular matrix, such as collagen deposition and elastin fragmentation, which reduces the artery's ability to buffer pressure changes and ultimately impairs vascular homeostasis.
