Aortic Pulse Wave Velocity Measured by Pulse Wave Imaging (pwi): a Comparison with Applanation Tonometry.
BACKGROUND Arterial stiffness is a well-established indicator of cardiovascular disease outcome. Pulse Wave Velocity (PWV) is a surrogate for arterial stiffness that is measured either globally using carotid to femoral applanation tonometry or locally using biomedical imaging methods. Pulse Wave Imaging (PWI) is an ultrasound-based method for both qualitative visualisation of pulse wave propaga...
متن کاملCorrelates of Aortic Pulse wave velocity measured by cardiac MRI
Methods 223 consenting nondiabetic, normotensive volunteers without clinical cardiovascular disease or echocardiographic abnormalities (124 females, 116 hyperlipidemic (42 treated), age: 58.6+/-14.9yrs, BMI: 24.8+/-3.3 (24 with BMI>28) were studied. CMR studies were performed on a 1.5 Tesla MR scanner (Siemens, Germany) using a phased array surface-coil and a spine-coil array. PWV was assessed ...
متن کاملDiurnal Variation of Pulse Wave Velocity Assessed Non-Invasively by Applanation Tonometry in Young Healthy Men
PURPOSE Pulse wave velocity (PWV) is at least partially controlled by vascular tone. Vascular tone and underlying physiological processes such as sympathetic activity, plasma catecholamin, and cortisol levels have been shown to follow diurnal variations. MATERIALS AND METHODS Carotid-to-radial PWV was non-invasively assessed by applanation tonometry in 21 young (26.5+/-2.3 years) healthy men ...
متن کاملRequired temporal resolution for accurate thoracic aortic pulse wave velocity measurements by phase-contrast magnetic resonance imaging and comparison with clinical standard applanation tonometry
BACKGROUND Pulse wave velocity (PWV) is a biomarker for arterial stiffness, clinically assessed by applanation tonometry (AT). Increased use of phase-contrast cardiac magnetic resonance (CMR) imaging allows for PWV assessment with minor routine protocol additions. The aims were to investigate the acquired temporal resolution needed for accurate and precise measurements of CMR-PWV, and develop a...
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...
