Local Shear Stress and Brachial Artery Flow–Mediated Dilation
Endothelium-dependent flow-mediated dilation is a homeostatic response to short-term increases in local shear stress. Flow-mediated dilation of the brachial artery in response to postischemic reactive hyperemia is impaired in patients with cardiovascular disease risk factors and may reflect local endothelial dysfunction in the brachial artery. However, previous studies have largely neglected th...
متن کاملBlood Flow of the Middle Cerebral Artery With Sleep-Disordered Breathing Correlation With Obstructive Hypopneas
Background and Purpose—Epidemiological data link heavy snoring to an increased risk for stroke, an association often ascribed to hypertension and/or sleep apnea. The aim of this study was to determine whether obstructive hypopneas, central apneas, or obstructive apneas during sleep alter blood flow of the middle cerebral artery (MCA). Methods—Doppler sonography of the MCA was performed in conju...

BACKGROUND AND PURPOSE Epidemiological data link heavy snoring to an increased risk for stroke, an association often ascribed to hypertension and/or sleep apnea.

متن کاملEffects of race and hypertension on flow-mediated and nitroglycerin-mediated dilation of the brachial artery.
Black Americans have increased morbidity and mortality rates from cardiovascular disease, greater prevalence of hypertension, and altered responses to vasodilator medications compared with those of white Americans. Hypertension and black race have been linked to impaired vascular function in the microcirculation. To examine these effects and their interaction in the conduit vasculature, we exam...
متن کاملBrachial artery flow-mediated dilation and asymmetrical dimethylarginine in the cardiovascular risk in young Finns study.
BACKGROUND Elevated asymmetrical dimethylarginine (ADMA) is a novel risk factor for atherosclerosis that may impair endothelial function by interfering with endothelial nitric oxide synthesis. To gain insight into the effects of ADMA on systemic endothelial function, we examined the association between ADMA and brachial artery flow-mediated dilation (FMD) in a large population of young adults. ...
