Optimization of arterial age prediction models based in pulse wave

Arterial pulse wave velocity and cognition with advancing age.

We hypothesized that carotid-femoral pulse wave velocity (PWV), a marker of arterial stiffness, interacts with age such that the magnitude of associations between PWV and cognitive performance are greater with increasing age and that this interaction is observed despite adjustments for demographic variables, mean arterial pressure, and cardiovascular risk factors. PWV was estimated using applan...

Pulse Wave Propagation in the Arterial Tree

The beating heart creates blood pressure and flow pulsations that propagate as waves through the arterial tree that are reflected at transitions in arterial geometry and elasticity. Waves carry information about the matter in which they propagate. Therefore, modeling of arterial wave propagation extends our knowledge about the functioning of the cardiovascular system and provides a means to dia...

Studies of the arterial pulse wave.

With the technical assistance of William Urban Previous studies have shown abnormalities of the arterial pulse wave in hypertensive subjects of all age groups. The major change has been diminution to disappearance of the dicrotic wave. The pharmacologic differences between epinephrine and norepi-nephrine offer a means of studying the mechanism of this change in the dicrotic wave. In the present...

Use of pulse wave analysis to measure arterial stiffness in old age.

SIR—We read with interest Fantin’s cross-sectional study comparing the influence of age on arterial stiffness using the technique of applanation tonometry with pulse wave analysis (PWA) [1]. Their study is particularly welcome since the literature contains few direct comparisons of different markers of arterial stiffness [2]. The overall PWA completion rate was 66% (302/458) for carotid tonomet...
