Radial artery flow-mediated dilatation in heart failure patients: effects of pharmacological and nonpharmacological treatment.
Congestive heart failure (CHF) is associated with an impaired flow-mediated vasodilation that reflects an impaired endothelial function. Limited information is available, however, on whether and to what extent this impairment is improved by pharmacological or nonpharmacological treatment. We measured radial artery diameter and blood flow by an echo-tracking Doppler device both at baseline and a...
متن کاملFlow-mediated dilatation of the basilar artery in vivo.
Flow-mediated dilatation has been described mainly in peripheral conduit arteries. The goal of this study was to examine mechanisms and functional implications of flow-mediated dilatation in large cerebral arteries in vivo. Vessel diameter and velocity of blood flow through the basilar artery were measured using a cranial window in 45 anesthetized rats. Mean blood flow velocity through the basi...
متن کاملReliability of brachial artery flow-mediated dilatation measurement using ultrasound.
OBJECTIVE To determine the reliability of the baseline (BBAB) and post occlusion (POBAD) brachial artery diameters, brachial artery flow-mediated dilatations (BAFMD) measurements, and to quantify the typical error of the measurements (TEM). METHODS Internal consistency (2 measurements on the same day) was determined in 10 volunteers, whereas stability (2 measurements on separate days) was det...
متن کاملFlow-dependent coronary artery dilatation in humans.
To determine the role of endothelium-mediated flow-dependent coronary dilatation in humans, we studied the coronary dilatation exerted by maximal pharmacologic increase of coronary flow in 14 patients with normal coronary arteries. Biplane views of the circumflex (Cx) and left anterior descending (LAD) coronary arteries were obtained before and 80 seconds after inducing a maximal increase in fl...
متن کاملReproducibility of brachial artery flow-mediated and glyceryl trintrate-mediated dilatation by 3Tesla CMR
Intra-observer and inter-study reproducibility of brachial artery flow-mediated dilatation (FMD) and glyceryl trintrate (GTN)-mediated dilatation by CMR at 3Tesla were assessed. Coefficients of variation (CoV) were calculated using the root mean square method. The intra-observer CoV, assessed in 15 subjects, was 15% for both FMD and GTN response. The inter-study CoV, assessed in 17 subjects, wa...
