Key result
Brachial-ankle pulse wave velocity is moderately correlated with stiffness parameters of the proximal abdominal aorta, such as strain (r=-0.203) and elastic modulus (r=0.304), mainly in normotensive subjects.
Why the study?
Does proximal abdominal aortic stiffness measured by ultrasound correlate with brachial-ankle pulse wave velocity in normotensive and hypertensive subjects?
Population
285 subjects, mean age 58.1 years, 58.9% female, recruited from a hypertension clinic in Seoul, Korea.

Effect estimate: r = -0.203
p-value: p=0.01
Brachial-ankle pulse wave velocity is moderately correlated with ultrasound-measured stiffness parameters of the proximal abdominal aorta, primarily in normotensive subjects.
Lim et al. (2013) conducted a cross-sectional in Hypertension and normal blood pressure (n=285). Proximal abdominal aortic stiffness was evaluated on Correlation between brachial-ankle pulse wave velocity (baPWV) and proximal abdominal aortic strain in normotensive subjects (r = -0.203, p=0.01). Brachial-ankle pulse wave velocity is moderately correlated with stiffness parameters of the proximal abdominal aorta, such as strain (r=-0.203) and elastic modulus (r=0.304), mainly in normotensive subjects.
