Aortic and large artery stiffness: current methodology and clinical correlations
1Department of Medicine, University of Massachusetts Medical Center, Worcester.
Artery stiffness increases with age and in conditions like diabetes and hypertension. Women experience accelerated stiffening post-menopause, matching men by their seventh decade.
Area of Science:
- Cardiovascular Physiology
- Biomedical Engineering
Background:
- Arterial stiffness is a key indicator of cardiovascular health.
- Aging and various diseases significantly impact large artery properties.
Purpose of the Study:
- To review current methodologies for determining aortic and large artery stiffness.
- To summarize clinical correlations of arterial stiffness with age, sex, and disease.
Main Methods:
- Pulse wave velocity (PWV) measurements for distensibility estimation.
- Imaging techniques (angiography, Doppler ultrasound) to assess fractional diameter changes.
- Windkessel model analysis for compliance determination via volume change.
Main Results:
- Artery stiffness increases progressively with age due to structural changes.
- Women show lower stiffness until menopause, then accelerated stiffening.
- Correlations observed with diabetes, hypertension, and advanced atherosclerosis (calcification).
Conclusions:
- Established methods exist for in vitro assessment of arterial stiffness.
- Arterial stiffness is influenced by aging, sex, and specific pathological conditions.
- Further research may clarify the complex relationship between atherosclerosis and stiffness.
