Pulse Wave Velocity: Methodology, Clinical Applications, and Interplay with Heart Rate Variability

Area of Science:

• Cardiovascular diagnostics
• Vascular physiology

Background:

• Pulse wave velocity (PWV) is a key biomarker for vascular health and cardiovascular risk assessment.
• It reflects arterial stiffness, crucial for monitoring conditions like hypertension and diabetes.

Purpose of the Study:

• To highlight the clinical significance of PWV in cardiovascular diagnostics.
• To address the challenges in PWV measurement standardization and confounding factors.
• To explore the integration of PWV with other physiological parameters for enhanced cardiovascular care.

Main Methods:

• Review of established measurement techniques including tonometry, Doppler ultrasound, oscillometric analysis, and MRI.
• Discussion of surrogate parameters like pulse arrival and transit times.
• Consideration of confounding factors such as sympathetic tone and heart rate variability (HRV).

Main Results:

• PWV is a valuable indicator of arterial stiffness and cardiovascular risk.
• Methodological variability and lack of standardization hinder consistent PWV assessment.
• A bidirectional relationship exists between HRV and PWV, indicating interplay between autonomic function and vascular health.

Conclusions:

• Standardization of PWV measurement techniques is essential for clinical utility.
• Integrating PWV and HRV with AI offers potential for personalized vascular health management.
• Further research is needed to refine PWV assessment and understand its physiological influences.
