[Arteriell wall-stiffness: a new important cardiovascular risk factor]

Area of Science:

• Cardiovascular Physiology
• Vascular Diagnostics
• Biomedical Engineering

Background:

• Blood pressure (BP) is a standard cardiovascular risk factor, but assessing arterial function requires additional parameters.
• Augmentation index (AIx) and pulse wave velocity (PWV) are emerging markers of arterial health.
• Early detection of vascular dysfunction is crucial for preventing end-organ damage.

Purpose of the Study:

• To highlight the diagnostic utility of AIx and PWV in assessing arterial function.
• To advocate for the clinical integration of AIx and PWV for early vascular risk identification.
• To compare the variability of AIx and PWV with traditional BP measurements.

Main Methods:

• Utilized AIx and PWV measurements to assess arterial function.
• Compared the diagnostic value of AIx and PWV against traditional risk factors and BP.
• Analyzed the variability of AIx and PWV recordings in hypertensive patients.

Main Results:

• AIx and PWV are independent predictors of vascular risk and end-organ damage.
• These parameters reflect vessel wall elasticity and hemodynamic conditions.
• AIx and PWV demonstrated lower variability in recordings compared to BP in hypertensive patients.

Conclusions:

• AIx and PWV offer a more direct assessment of vascular health than risk scores.
• These techniques are valuable for early risk diagnostics, potentially preceding anatomical changes.
• Implementing AIx and PWV in clinical practice can improve cardiovascular disease management.
