Key result
Aortic pulse wave velocity measured in the sitting position without prior relaxation (10.58 m/s) did not significantly differ from measurements taken in the supine position after relaxation (10.29 m/s, p=0.857).
Why the study?
Assessing arterial stiffness via pulse wave velocity provides early cardiovascular risk data, but oscillometric measurements needed adaptation for convenient use in outpatient screening examinations.
Can pulse wave velocity measured in the sitting position accurately estimate supine pulse wave velocity for outpatient screening?

Absolute Event Rate: 10.58% vs 10.29%
p-value: p=0.857
Oscillometric measurement of pulse wave velocity in the sitting position can accurately estimate supine values using a derived formula, facilitating convenient outpatient screening for arterial stiffness.
May enable convenient outpatient PWV screening via sitting measurements; leaves open need for outcome validation studies.
Background. Estimation of the parameters of arterial stiffness allows one to make conclusions about the development of CVD long before clinical manifestations of the target organ damage. The determination of the pulse wave velocity (PWV) is the «gold standard» for the arterial wall stiffness assessment. The oscillometric method of PWV measurement has a number of advantages (convenience and high speed) over the most common «two-point» techniques. Objective. The purpose of this work was to adapt the PWV measurement using the oscillometric method for screening outpatient examinations. Using a BPLab Vasotens diagnostic oscillometric system (Russia), PWV was measured in 152 patients, and a formula was obtained for recalculating PWV values in the supine position on the basis of PWV values in the sitting position. Methods. Using a BPLab Vasotens diagnostic system, PWV was measured in 152 patients, and a formula was derived for recalculating PWV values in the supine position on the basis of PWV values in the sitting position. Results. Measuring aortal PWV in the sitting position gave an opportunity of a simultaneous study of the central and peripheral BP parameters and the arterial wall stiffness. The obtained data may be used during patients’ screening in the outpatient setting. Conclusion. The use of the screening procedure for the PWV measurement in the outpatient practice will allow concluding on the CVD development long before clinical manifestations of the target organs damage and will rid the patient of a possibility of a wrong estimation of their cardiovascular risk.

Tkachenko et al. (2019) conducted a cross-sectional in Arterial hypertension, ischemic heart disease, and healthy volunteers (n=152). Oscillometric measurement of pulse wave velocity in sitting position vs. Oscillometric measurement of pulse wave velocity in supine position after 15 minutes of relaxation was evaluated on Aortic pulse wave velocity (PWVao) (p=0.857). Aortic pulse wave velocity measured in the sitting position without prior relaxation (10.58 m/s) did not significantly differ from measurements taken in the supine position after relaxation (10.29 m/s, p=0.857).
