Key result
Increased BMI (30-35 kg/m2) was associated with higher arterial stiffness compared to normal BMI (20-25 kg/m2) as measured by carotid-femoral pulse wave velocity (10.1 vs 9.1 m/s, p=0.011).
Why the study?
Do Vicorder PWV and stiffness index (SI) correlate with reference carotid-femoral PWV, and how do these measures relate to age, BMI, and central blood pressure in adults?
Cross-Sectional (n=183)
No

Absolute Event Rate: 10.1% vs 9.1%
p-value: p=0.011
Vicorder PWV is a more reproducible and better-correlated alternative to SphygmoCor for measuring arterial stiffness than the digital stiffness index.

Caution against inferring causality from BMI-PWV association; hypothesis-generating for weight-loss effects on arterial stiffness.
Maniou et al. (2010) conducted a cross-sectional in Healthy adults (n=183). Increased BMI (30-35 kg/m2) vs. Normal BMI (20-25 kg/m2) was evaluated on Carotid to femoral pulse wave velocity (PWVc-f) in m/s (p=0.011). Increased BMI (30-35 kg/m2) was associated with higher arterial stiffness compared to normal BMI (20-25 kg/m2) as measured by carotid-femoral pulse wave velocity (10.1 vs 9.1 m/s, p=0.011).
