Improved analysis of brachial artery
ultrasound using a novel edge-detection software system.
The brachial artery
was then allowed to return to normal for ten minutes, and repeat baseline images were obtained.
Interrelationship between noninvasive predictors of atherosclerosis: transthoracic coronary flow reserve, flowmediated dilation, carotid intima-media thickness, aortic stiffness, aortic distensibility, elastic modulus, and brachial artery
4mg sublingual, Nitrolingual sprey, Pohl-Boskamp) of the brachial artery
were assessed by high-resolution ultrasound (7.
Measuring brachial artery
blood flow is a complicated technique.
Caffeine and hot water did not yield significant effects, but there was a 4% peak increase in endothelium-dependent brachial artery
dilatation 30 minutes after the subjects consumed green tea.
Flow-mediated vasodilation of the brachial artery
was measured using ultrasound to assess elasticity of the endothelium (blood vessel lining).
flow-mediated dilation (FMD) was measured prospectively in all patients by using high-resolution ultrasound.
A research team from Harbor-UCLA Medical Center reported a direct relationship between brachial artery
elasticity, as measured by a non-invasive DynaPulse hemodynamic monitor, and coronary artery plaque burden, obtained by Electron Beam Computed Tomography (EBCT), at the American Heart Association's 2001 Scientific Sessions today in Anaheim, California.
All studies assessed endothelial function by measuring the change in brachial artery
flow-mediated dilation after folic acid supplementation, compared with the change following administration of a placebo.
We have designed the Phase IIa LUV study to also evaluate vascular reactivity using brachial artery
ultrasound and inflammatory markers including high sensitivity C-reactive protein, soluble VCAM and soluble ICAM and will include a vascular structure sub-study using magnetic resonance imaging (MRI) of the aorta and carotid arteries," added Dr.
Endothelial dysfunction was identified based on impaired flow-mediated vasodilation of the brachial artery
using high-resolution ultrasound.
