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...
متن کاملEffects of metabolic syndrome on aortic pulse wave velocity
BACKGROUND The purpose of this study was to compare the value and evaluate the validity of non-invasive methods for the detection of vascular stiffness in never-treated individuals with metabolic syndrome (MetS). METHODS A total of 59 subjects (mean age, 60 ± 12 years; male:female = 35:24) were enrolled in the study and were categorized into the positive MetS (MetS[+]: N = 32) and negative gr...
متن کاملPulse wave velocity measurement
The article deals with the investigation of pulse wave propagation in arteries. A part of work involves also design and realization of devices serving for scanning of pulse wave by reflective photoplethysmography. The work describes a use of microcontroller serving for data flow control, communication and analog signal digitalization using integrated analog to digital converter.
متن کاملPulse 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...
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...
