Measurement of pulse wave velocity in normal ageing: comparison of Vicorder and magnetic resonance phase contrast imaging.

ABSTRACT:

Background

Pulse wave velocity is an important measure of cardiovascular risk, and can be measured by several different techniques. We compared age-related changes in pulse wave velocity derived from carotid and femoral artery waveforms using the Vicorder device and descending thoracic aorta time velocity curves using phase contrast magnetic resonance imaging (MRI) in a group of normal healthy volunteers, without cardiovascular disease, aged between 20 and 79 years.

Methods

Eighty subjects underwent same-day measurements of Vicorder and MRI pulse wave velocity measurements.

Results

Both Vicorder and MRI-based pulse wave velocity measurements were significantly increased with age (R = 0.59 and 0.57 respectively, both P < 0.0001). Vicorder and MRI pulse wave velocities
