Markers of arterial stiffness in peripheral arterial disease

Area of Science:

• Cardiovascular Physiology
• Vascular Medicine

Background:

• Arterial stiffness, a reduction in arterial wall elasticity, independently predicts cardiovascular risk.
• It is associated with conditions like systolic hypertension and peripheral arterial disease (PAD).

Purpose of the Study:

• To review the physiology of pulse wave propagation and reflection.
• To discuss non-invasive assessment techniques for arterial stiffness.
• To emphasize the importance of arterial pulse wave analysis in PAD management.

Main Methods:

• Review of physiological principles of pulse wave analysis.
• Discussion of non-invasive assessment techniques including carotid-femoral pulse wave velocity.
• Exploration of surrogate markers like central aortic pulse pressure and augmentation index.

Main Results:

• Carotid-femoral pulse wave velocity is the gold standard for assessing arterial stiffness.
• Pulse wave analysis provides insights into wave reflection characteristics.
• Aging and atherosclerosis significantly alter pulse wave dynamics.

Conclusions:

• Understanding arterial pulse wave analysis is vital for vascular specialists and primary care physicians.
• This knowledge aids in the context of peripheral arterial disease (PAD) diagnosis and management.
• Arterial stiffness assessment is critical for cardiovascular risk stratification.
