Aortic Pulse Wave Analysis Is Not a Surrogate for Central Arterial Pulse Wave Velocity

Central aortic pressure influences pulse wave velocity.

Central Aortic Pressure Influences Pulse Wave Velocity To the Editor: The study reported by Lantelme and colleagues1 suggests that increasing heart rate is independently associated with higher aortic pulse wave velocity (PWV). We are concerned that the authors of this study have neither addressed the impact of central aortic pressure changes on PWV nor the presence of potential bias in their st...

Pulse Wave Analysis and Pulse Wave Velocity

momanometer that provides arterial pressures (brachial systolic and diastolic pressure) is coming under question. The concerns extend well beyond the familiar issue of “white coat” hypertension, home and 24-h blood pressure recordings, and the phase-out of mercury based instruments. These concerns relate to the inaccuracy of all cuff devices for measuring pressure within the brachial artery, th...

Determination of aortic pulse wave velocity from waveform decomposition of the central aortic pressure pulse.

Aortic pulse wave velocity (PWV), calculated from pulse transit time (PTT) using 2 separate pulse recordings over a known distance, is a significant biomarker of cardiovascular risk. This study evaluates a novel method of determining PTT from waveform decomposition of central aortic pressure using a single pulse measurement. Aortic pressure was estimated from a transformed radial pulse and deco...

Arterial pulse wave velocity and heart rate.

Arterial Pulse Wave Velocity and Heart Rate

To the Editor: The concerns raised by Lantelme et al1 about the relationship between heart rate and pulse wave velocity (PWV) properly apply to the method they employed, not to the conventional method, nor to the long-established relationship between PWV and arterial stiffness. Lantelme et al used Complior, as did the 3 other studies (Lantelme references 8, 15, 17), which appeared to show incre...
