Key result
Oscillometric arterial stiffness index positively correlates with carotid-femoral pulse wave velocity in hypertensive patients.
Why the study?
Arterial stiffness is a predictor of cardiovascular events and is commonly measured by carotid-femoral pulse wave velocity, but a convenient upper arm arterial stiffness index was recently developed and requires evaluation in elderly hypertensive patients.
Does the arterial stiffness index measured by computerized oscillometry correlate with established methods of evaluating arterial stiffness in patients with essential hypertension?

Supports oscillometric arterial stiffness index as PWV correlate; leaves open outcome validation before clinical use in hypertension.

Does the arterial stiffness index measured by computerized oscillometry correlate with established methods of evaluating arterial stiffness in patients with essential hypertension?
Effect estimate: r = 0.579
p-value: p=< 0.0001
The arterial stiffness index measured by computerized oscillometry at the upper arm correlates well with established pulse wave velocity measurements, offering a convenient alternative for evaluating arterial stiffness in hypertensive patients.
Kaibe et al. (2002) conducted a cross-sectional in Essential hypertension (n=42). Arterial stiffness index by computerized oscillometry vs. Pulse wave velocity and other arterial stiffness evaluation methods was evaluated on Correlation with pulse wave velocity between the carotid-femoral artery (r = 0.579, p=< 0.0001). Arterial stiffness index measured by computerized oscillometry positively correlated with carotid-femoral pulse wave velocity (r = 0.579, P < 0.0001) in hypertensive patients.
