Low-flow mediated constriction is endothelium-dependent: effects of exercise training after radial artery catheterization.
BACKGROUND Radial artery catheterization is associated with endothelial denudation and impaired vasodilator function, while postcatheterization exercise training may enhance artery function. The impact of catheterization and subsequent exercise training on low-flow mediated vasoconstriction (L-FMC) has not previously been studied. The aim of this study was to examine whether radial artery L-FMC...
متن کاملLeukotriene constriction of mouse pial arterioles in vivo is endothelium-dependent and receptor-mediated.
The diameters of pial arterioles of mice were monitored in vivo with an image-splitting technique and television microscopy. Concentrations of leukotriene C4 as low as 10(-7) M constricted the arterioles. The leukotriene C4-D4 receptor blocker ICI 198615 (10(-8) M) inhibited the response. Endothelial injury by helium-neon laser/Evans blue technique eliminated the constriction and unmasked a sli...
متن کاملLow flow-mediated constriction: prevalence, impact and physiological determinant.
Flow-mediated dilation (FMD) is a surrogate marker for endothelial function. In the FMD procedure, arterial response during cuff inflation is not taken into consideration yet studies have demonstrated vasoconstriction, vasodilation and no change in the brachial artery during cuff inflation. The term low flow-mediated constriction (L-FMC) has been introduced to describe the vasoconstriction that...
متن کاملNormal pregnancy is associated with enhanced endothelium-dependent flow-mediated vasodilation.
Normal pregnancy is characterized by reduced systemic vascular resistance, which may be mediated by nitric oxide (NO). We compared endothelial vasomotor function in 71 normal pregnant women (13 in first, 29 in middle, and 29 in last trimester) to 37 healthy age-matched controls. With external ultrasound, brachial artery diameter was measured at rest, during reactive hyperemia [with increased fl...
متن کاملEndothelium-dependent flow-mediated vasodilation of systemic arteries is impaired in patients with myocardial virus persistence.
BACKGROUND Myocardial virus persistence is frequently observed in patients with cardiomyopathy. Endothelial dysfunction in patients with cardiomyopathy is associated with inflammatory immunoresponses in myocardial biopsies. The aim of this study was to investigate the impact of myocardial virus persistence on endothelial function. METHODS AND RESULTS In 124 patients with suspected cardiomyopa...
