What is the best path length for aortic pulse wave velocity? Preliminary answer to a stiff question.
A compliant (nonstiffened) aorta enables optimal cardiac function and appropriate transfer of stroke volume without major elevations in left ventricular afterload. Increased aortic stiffness, on the other hand (which commonly occurs with aging and hypertension), impairs ventricular–vascular interaction, decreases cardiac performance through raised afterload, and is a powerful independent predic...

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...
متن کاملWhat Is the Best Research Globally?
Dr. Afshari’s editorial gives insight on human nature (1). Collaborative willingness usually occurs when different sides perceive personal benefit, or when institutions mandate collaboration. This is not unique between higher and lower income countries; many working in global emergency medicine (EM) observe this within wealthier countries. It exists among collaborators in low resource settings....
متن کاملLocation of a reflection site is elusive: consequences for the calculation of aortic pulse wave velocity.
Aortic pulse wave velocity (PWV), a measure of aortic stiffness, is an important indicator of cardiovascular risk. Derivation of PWV from uncalibrated proximal aortic or carotid pressure alone has practical advantages. However, when the time of return of the reflected wave, (Delta)t, is used to calculate PWV, inaccurate data are obtained. With aging PWV increases but (Delta)t hardly decreases, ...
متن کاملAortic length measurements for pulse wave velocity calculation: manual 2D vs automated 3D centreline extraction
BACKGROUND Pulse wave velocity (PWV) is a biomarker for the intrinsic stiffness of the aortic wall, and has been shown to be predictive for cardiovascular events. It can be assessed using cardiovascular magnetic resonance (CMR) from the delay between phase-contrast flow waveforms at two or more locations in the aorta, and the distance on CMR images between those locations. This study aimed to i...
