Key result
baPWV predicts hypertension better than large artery elasticity, achieving an AUC of ~0.83.
Why the study?
Only a few small studies have compared arterial stiffness indices measured by pulse wave velocity and pulse wave analysis.
Does brachial-ankle pulse wave velocity have a better predictive value for hypertension compared to pulse wave analysis in a general population?

baPWV better discriminates Framingham risk than elasticity indices in this cohort; leaves open superiority for clinical stratification.
Cross-Sectional (n=4,285)
Does brachial-ankle pulse wave velocity have a better predictive value for hypertension compared to pulse wave analysis in a general population?
Effect estimate: AUC 0.834 (95% CI 0.821-0.845)
Absolute Event Rate: 0.834% vs 0.701%
Brachial-ankle pulse wave velocity is a superior method for predicting hypertension compared to large and small artery elasticity measured by pulse wave analysis.
Zhu et al. (2019) conducted a cross-sectional in Hypertension (n=4,285). Brachial-ankle pulse wave velocity vs. Pulse wave analysis (large and small artery elasticity) was evaluated on Area under the receiver operating characteristic curve for predicting hypertension (AUC 0.834, 95% CI 0.821-0.845). Brachial-ankle pulse wave velocity had a significantly larger area under the curve for predicting hypertension (AUC 0.834; 95% CI 0.821-0.845) compared to large artery elasticity (AUC 0.701).
