Measurement of pulse wave velocity in normal ageing: comparison of Vicorder and magnetic resonance phase contrast imaging
Why the study?
Does the Vicorder device perform similarly to phase contrast MRI in detecting age-related changes in pulse wave velocity in healthy volunteers?
Population
80 normal healthy volunteers, without cardiovascular disease, aged between 20 and 79 years
Comparison

Implication
Both methods track age-related PWV increases in healthy volunteers; leaves open interchangeability for clinical use given modest correlation and bias.
Structured PICO

P
Population
80 normal healthy volunteers, without cardiovascular disease, aged between 20 and 79 years
I
Intervention
Pulse wave velocity measurement using Vicorder device (derived from carotid and femoral artery waveforms)
C
Comparator
Pulse wave velocity measurement using phase contrast magnetic resonance imaging (MRI) (derived from descending thoracic aorta time velocity curves)
O
Outcome
Age-related changes in pulse wave velocity and agreement between the two measurement techniquessurrogate
Both Vicorder and MRI perform similarly in detecting age-related changes in pulse wave velocity, suggesting the choice of modality can be based on the need for portability versus comprehensive cardiovascular imaging.
