Comparison of brachial–ankle pulse wave velocity and carotid–femoral pulse wave velocity in association with albuminuria in a community of Beijing: a cross-sectional study

In a community-based population in Beijing, this research was done to investigate and compare albuminuria's relationship with the brachial–ankle pulse wave duration and carotid–femoral pulse wave velocity. Both baPWV and cfPWV were strongly associated with albuminuria in the multivariate logistic regression model adjusted for potential covariates. Both cfPWV and baPWV were positively linked to albuminuria, though baPWV had a greater relationship than cfPWV. Therefore, a baPWV test could be used for the purpose of community health screening.

Improving the accuracy and robustness of carotid-femoral pulse wave velocity measurement using a simplified tube-load model

The gold standard for aortic stiffness is Carotid-femoral pulse wave velocity. Existing algorithms for cfPWV estimation have been shown to have high repeatability and precision, but further testing is required, particularly when signal quality is compromised. The method and its effectiveness were compared to three other existing approaches, with In-vivo cfPWV measurements from 57 subjects and numerical cfPWV results based on a one-dimensional model used to evaluate the procedure and its results. The calculation of cfPWV based on the latest technology allows arterial stiffness to be determined more precisely and robustly.
