Key result
htPWV strongly correlates with cfPWV with no significant difference in mean values.
Why the study?
A novel arterial stiffness index was developed to eliminate transducer placement on carotid and femoral arteries, prompting evaluation of its agreement with carotid-femoral pulse wave velocity.
Does heart-thigh pulse wave velocity (htPWV) agree with carotid-femoral pulse wave velocity (cfPWV) for measuring arterial stiffness in adults?
Population
50 adults (28 men and 22 women) varying widely in age and blood pressure
Comparison

htPWV may simplify arterial stiffness screening; leaves open whether it predicts outcomes as robustly as cfPWV.

Heart-thigh pulse wave velocity is a novel, operator-independent method that shows good agreement with standard carotid-femoral pulse wave velocity for assessing arterial stiffness.
Fico et al. (2019) reported a cross-sectional. Heart-thigh pulse wave velocity (htPWV) vs. Carotid-femoral pulse wave velocity (cfPWV) was evaluated on Pulse wave velocity (cm/s) (r 0.64, p=<0.001). Heart-thigh pulse wave velocity (htPWV) demonstrated a strong linear association with carotid-femoral pulse wave velocity (r=0.64, P<0.001) with no significant difference in mean values (699 vs 713 cm/s, P=0.43).
