Pulse Wave Velocity

Definition

Pulse Wave Velocity (PWV) is a measure of the speed at which pressure waves move down the vessel. It is an indicator of arterial stiffness, which can affect cardiovascular health.

Scientific / Technical Definition

Pulse Wave Velocity is the velocity at which the blood pressure pulse propagates through the circulatory system. It is often used as a surrogate marker for arterial stiffness and is calculated by measuring the time it takes for the pulse wave to travel between two predetermined points in the body. Higher PWV values indicate greater arterial stiffness and are associated with increased risk of cardiovascular events.

Benefits

• Helps identify arterial stiffness
• Used as a predictor for cardiovascular diseases
• Non-invasive method to assess vascular health

Examples

• Clinical measurement devices
• Cardiovascular health assessments

Additional Information

• Effects: This metric provides insight into arterial health and can help guide lifestyle and dietary modifications for improved cardiovascular outcomes.
