Pulse Wave Velocity in Kawasaki Disease

Angiology, 2016
Kawasaki disease (KD) is an acute childhood febrile disease of unknown etiology. It exhibits not only coronary artery aneurysms in some cases but also systemic vasculitis. Whether KD is associated with accelerated atherosclerosis remains debatable. The measurement of pulse wave velocity (PWV) is useful as a simple, noninvasive measurement of arterial ...

Reproducibility of Pulse Wave Analysis and Pulse Wave Velocity in Healthy Subjects

Proceedings of the International Conference on Bio-inspired Systems and Signal Processing, 2014
The hemodynamic parameters extracted from pulse pressure waveform, by pulse wave analysis (PWA) and pulse wave velocity (PWV) are strong independent predictors of cardiovascular morbidity. The aim of this study is to investigate the reproducibility of pulse pressure profile and arterial stiffness indicators, i.e., Augmentation Index (AIx ...

Carotid–femoral pulse wave velocity in the elderly

Journal of Hypertension, 2014
Predictive value of arterial stiffness in cardiovascular disease has been recognized for many decades. Carotid-femoral pulse wave velocity (cfPWV), as a noninvasive measurement, has been recommended as a gold standard of arterial stiffness, and we believe that this surrogate of arterial stiffness has been refined to the point that its utility in ...

[Pulse wave velocity].

Rinsho byori. The Japanese journal of clinical pathology, 2004
Pulse wave velocity (PWV) reflects arterial stiffness. PWV correlates with other markers reflecting the severity of atherosclerosis such as the findings of ultrasound examination of carotid artery. In addition, several studies demonstrated that increased PWV is a predictor of future cardiovascular events in patients with either hypertension or diabetes

Wave Travel and Pulse Wave Velocity

2018
Waves generated by the heart travel down the aorta and major conduit arteries. These waves are pressure waves, flow or velocity waves or diameter waves. The ratio of the distance Δx, and the time it takes for the foot of the wave to travel over this distance, Δt, gives the wave speed or pulse wave velocity, PWV=Δx/Δt.

[A noninvasive method for radial pulse-wave velocity and the determinants of pulse-wave velocity].

Sheng wu yi xue gong cheng xue za zhi = Journal of biomedical engineering = Shengwu yixue gongchengxue zazhi, 2003
An effective experimental method has been proposed and used to determine the pulse-wave velocity (PWV) of 257 radial pulse signals. Experimental results show that, compared with the normal pulse, the wiry pulse has an increased PWV(P < 0.01 or P < 0.05), the thready pulse has a decreased PWV(P < 0.05), but the PWV of the smooth pulse is not ...

[Measurement of the velocity of the pulse wave].

Bollettino della Societa italiana di biologia sperimentale, 1980
Pulse wave transmission rate has been measured "in vivo" in 6 male anaesthetized Wistar rats, by means of cannulae, inserted both in carotid and femoral arteries. The measure has been done by calculating the time delay of several corresponding levels in the two pressure pulses: at the foot, during the ascending phase, at the peak.

[Arteriosclerosis and pulse wave velocity].

Nihon rinsho. Japanese journal of clinical medicine, 2004
Impairment of the arterial compliance or loss of Windkessel effect of elastic arteries causes increased afterload to the heart and increased pulsatile flow to the peripheral vasculatures. The former induces left ventricular hypertrophy or dysfunction and the latter induces small vessel damage or end organ dysfunction.

[Pulse wave velocity(PWV)].

Nihon rinsho. Japanese journal of clinical medicine, 2004
Brachial-ankle pulse wave velocity(baPWV) is a noninvasive and simple method of measuring arterial stiffness and an independent predictor of cardiovascular mortality in some lifestyle-related diseases. We evaluated that baPWV is well correlated with many atherosclerotic risk factors including abdominal visceral obesity and HOMA, and that the ...
