Pulse wave velocity (PWV) is a measure of how quickly pressure waves travel through the arteries. It reflects the stiffness of the arterial walls; stiffer arteries allow pressure waves to move faster. PWV is often assessed using non-invasive techniques, such as ultrasound or tonometry, to monitor cardiovascular health. Higher PWV values can indicate an increased risk of cardiovascular diseases, as they are associated with conditions like hypertension and atherosclerosis. Regular monitoring of PWV can help healthcare providers evaluate the effectiveness of treatments and lifestyle changes aimed at improving heart health.
