Pulsatile hemodynamics and microcirculation: evidence for a close relationship in hypertensive patients.
The possible relationships between indicators of small resistance artery structure and of arterial stiffness and central hemodynamics have not yet been evaluated. Aim of this study was to assess the relationship between indicators of large arteries stiffness, including carotido-femoral pulse wave velocity and of vascular alterations in small resistance arteries (media/lumen ratio, M/L) in patie...
متن کاملNetwork model of pulsatile hemodynamics in the microcirculation of the rabbit omentum.
GROSS, JOSEPH F., MARCOS INTAGLIETTA, AND BENJAMIN W. ZWEIFACH. Network model of pulsatile lzemodynamics in the microcirculation of the rabbit omentum. Am. J. Physiol. 226(5) : 1117-l 123. 1974.-Pulsatile pressure and red cell velocities were measured throughout the microvasculature of the rabbit omentum as a function of the order of branching. The data were analyzed in terms of a network model...
متن کاملEvaluating microcirculation by pulsatile laser Doppler signal.
Laser Doppler flowmetry (LDF) is a popular method for monitoring the microcirculation, but it does not provide absolute measurements. Instead, the mean flux response or energy distribution in the frequency domain is generally compared before and after stimulus. Using the heartbeat as a trigger, we investigated whether the relation between pressure and flux can be used to discriminate different ...
متن کاملPulsatile hemodynamics in congestive heart failure.
Pulse pressure, an indirect measure of vascular stiffness and pulsatile load, predicts clinical events in congestive heart failure (CHF), suggesting that abnormal pulsatile load may contribute to CHF. This study was designed to assess more direct measures of central pulsatile load in CHF. Noninvasive hemodynamic evaluations were performed in 28 subjects with CHF and 40 controls using calibrated...
متن کاملHemodynamics of gastric microcirculation in rats.
Recently, we described a novel preparation of rat stomach for vascular micropuncture studies. The aim of the present study was to directly measure basic microvascular parameters along the length of the gastric vasculature. Blood vessels were identified, and intravascular pressure was measured with a servo-null transducer, vessel dimensions with videometry, blood flow with microspheres, and plas...
