Population
71 healthy men and women aged 20 to 69 years
Design
Cross-sectional
Key result
Advancing age was independently associated with increased aortic input impedance, showing a 37% increase in the frequency of the minimum modulus between the third and seventh decade (P<0.0001).

Age-associated aortic impedance rise may contribute to cardiovascular risk; hypothesis-generating, requiring prospective studies before any clinical application.
Cross-Sectional (n=71)
Effect estimate: r=0.48
p-value: p=<0.0001
Aortic input impedance increases with advancing age in healthy individuals, which may be a mechanism for age-related cardiovascular risk.
Mazzaro et al. (2005) conducted a cross-sectional in Healthy (n=71). Advancing age was evaluated on Frequency of the minimum modulus of aortic input impedance (r=0.48, p=<0.0001). Advancing age was independently associated with increased aortic input impedance, showing a 37% increase in the frequency of the minimum modulus between the third and seventh decade (P<0.0001).
