Key result
Age was strongly correlated with pulse wave velocity (r = 0.901) but poorly correlated with short-term systolic blood pressure variability (r = 0.492) in adults aged 60 years and older.
Why the study?
Studies have separately compared the association of age with blood pressure variability or pulse wave velocity, but their association in the same sample remained to be established.
Population
508 under 60 years and 141 in their sixties (≥ 60)
Comparison
Age < 60 years vs age ≥ 60 years

Supports prioritizing PWV over BPV for age-related vascular assessment; leaves open independent prognostic value in longitudinal studies.

Effect estimate: r = 0.901 (95% CI 0.865-0.928)

Pulse wave velocity metrics are significantly more influenced by age than short-term blood pressure variability.
Silva et al. (2025) conducted a cross-sectional in Hypertension (n=649). Age was evaluated on Correlation between age and oscillometric pulse wave velocity (br-PWV) in adults ≥60 years (r = 0.901, 95% CI 0.865-0.928, p=<0.001). Age was strongly correlated with pulse wave velocity (r = 0.901) but poorly correlated with short-term systolic blood pressure variability (r = 0.492) in adults aged 60 years and older.
