Supports PWV use by newly trained personnel in elderly; leaves open whether it should change practice or guide outcomes.
Is aortic pulse wave velocity measurement reproducible in elderly patients when performed by newly trained sonographers and readers?
Aortic pulse wave velocity measurement is a reproducible method for assessing arterial stiffness in elderly populations, even when performed by newly trained sonographers and readers.
A 2001 study studied this question.
