Key result
Aortic characteristic impedance independently predicted left ventricular mass in women (β = 0.14, P<0.05) and men (β = 0.11, P<0.05), and relative wall thickness in women (β = 0.21, P<0.01).
Why the study?
Is aortic characteristic impedance associated with left ventricular mass and geometry independently of blood pressure in untreated hypertensive individuals?
Population
438 never-treated hypertensive individuals (men 62%, age 48 ± 11 years, BP 147/90 ± 16/10 mm Hg)
Design
Cross-sectional

Is aortic characteristic impedance associated with left ventricular mass and geometry independently of blood pressure in untreated hypertensive individuals?
Effect estimate: β = 0.14
p-value: p=<0.05
Aortic characteristic impedance is associated with left ventricular mass and geometry in untreated hypertension, independent of 24-hour systolic blood pressure.
Pucci et al. (2014) conducted a cross-sectional in Untreated hypertension (n=438). Aortic characteristic impedance (Zc) was evaluated on Left ventricular mass and relative wall thickness (β = 0.14, p=<0.05). Aortic characteristic impedance independently predicted left ventricular mass in women (β = 0.14, P<0.05) and men (β = 0.11, P<0.05), and relative wall thickness in women (β = 0.21, P<0.01).
