Key result
Aging had a stronger correlation with central aortic pulse wave velocity (r=0.474, P<0.001) than with peripheral radial pulse wave velocity (r=0.224, P=0.003).
Why the study?
Does aging have differing effects on central versus peripheral blood pressures and pulse wave velocity?
Observational (n=175)
Does aging have differing effects on central versus peripheral blood pressures and pulse wave velocity?
Effect estimate: r = 0.474
p-value: p=<0.001
Aging has a greater effect on central rather than peripheral arterial hemodynamics, predominantly affecting central pulse pressure due to central arterial stiffness.

Suggests prioritizing central over peripheral arterial assessment in aging; leaves open causal links to outcomes pending longitudinal data.
Choi et al. (2010) conducted an observational in Undergoing coronary angiography (n=175). Aging was evaluated on Correlation of age with aortic arch-abdominal aorta pulse wave velocity (aoPWV) (r = 0.474, p=<0.001). Aging had a stronger correlation with central aortic pulse wave velocity (r=0.474, P<0.001) than with peripheral radial pulse wave velocity (r=0.224, P=0.003).
