Aortic Pulse-Wave Velocity in Chickens and Ducks

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...

Aortic pulse wave velocity in normals and heart failure patients

Background Aortic compliance (AC) can be evaluated noninvasively and its reduction with aortic pathology and age in normals has been demonstrated with both MRI and Doppler echo methods. Aortic pulse wave velocity (PWV), a measurement of the flow pulse traveling along aorta as a surrogate for AC, can be assessed using a single breath-hold phase contrast (PC) imaging technique. Congestive heart f...

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...

Optimized Estimation of Global and Regional Aortic Pulse Wave Velocity

Introduction: Pulse wave velocity (PWV) as a measure of aortic stiffness is an important clinical marker for the presence of atherosclerosis [1,2]. For PWV estimation using Phase contrast (PC) MRI transit-time (TT) methods have been employed which estimate temporal differences in flow waveforms between two locations in the vessel with known distance [3]. However, precision was limited by the ac...
