Key result
Age and MAP strongly affect PWV measurements, while female sex increases measurement difficulty.
Why the study?
To facilitate large longitudinal studies using repeated pulse wave velocity measurements by identifying factors that reduce within-subject variability and minimize measurement difficulties across devices.
Do experimental, meteorological, and physiological factors affect short-term repeated pulse wave velocity measurements and measurement difficulties in adults?
RCT (n=35)
Single-blind

Do experimental, meteorological, and physiological factors affect short-term repeated pulse wave velocity measurements and measurement difficulties in adults?
Various physiological, meteorological, and experimental factors significantly affect repeated pulse wave velocity measurements, highlighting the need to standardize measurement protocols to reduce within-subject variability.
No takes yet. Share an insight, caveat, or question.
Standardize PWV protocols for age, MAP, sex, and time of day; extends RCT evidence on reducing arterial stiffness measurement variability.
Podrug et al. (2023) conducted an RCT in Arterial stiffness measurement variability (n=35). SphygmoCor CvMS and Arteriograph devices was evaluated on Factors affecting pulse wave velocity measurements and measurement difficulties. Age and mean arterial pressure strongly affected both carotid-femoral and aortic pulse wave velocity measurements, while female sex significantly increased and afternoon recording decreased measurement difficulties.
