Flow-mediated dilation and cardiovascular event prediction: does nitric oxide matter?
Endothelial dysfunction is an early atherosclerotic event that precedes clinical symptoms and may also render established plaque vulnerable to rupture. Noninvasive assessment of endothelial function is commonly undertaken using the flow-mediated dilation (FMD) technique. Some studies indicate that FMD possesses independent prognostic value to predict future cardiovascular events that may exceed...

Background & Aims : This research was aimed to investigate hypertension Adrenergic Receptor B2 (ADRB2) gene expression and Flow Mediate Dilation (FMD) level in untrained middle-aged men fallowing to eight week regular exercise training. Materials & Methods : This study was a semi-experimental research with a repeated measures design. From 96 volunteer middle-aged men, 20 subject (age range ...
متن کاملLetter to the editor: "Assessment of flow-mediated dilation in humans: a methodological and physiological guideline".
Endothelial dysfunction is now considered an important early event in the development of atherosclerosis, which precedes gross morphological signs and clinical symptoms. The assessment of flow-mediated dilation (FMD) was introduced almost 20 years ago as a noninvasive approach to examine vasodilator function in vivo. FMD is widely believed to reflect endothelium-dependent and largely nitric oxi...
متن کاملUltrasound Assessment of Endothelial Function: A Technical Guideline of the Flow-mediated Dilation Test.
Cardiovascular disease is the primary cause of mortality and a major cause of disability worldwide. The dysfunction of the vascular endothelium is a pathological condition characterized mainly by a disruption in the balance between vasodilator and vasoconstrictor substances and is proposed to play an important role in the development of atherosclerotic cardiovascular disease. Therefore, a preci...
متن کاملAn acute rise in intraluminal pressure shifts the mediator of flow-mediated dilation from nitric oxide to hydrogen peroxide in human arterioles.
Endothelial nitric oxide (NO) is the primary mediator of flow-mediated dilation (FMD) in human adipose microvessels. Impaired NO-mediated vasodilation occurs after acute and chronic hypertension, possibly due to excess generation of reactive oxygen species (ROS). The direct role of pressure elevation in this impairment of human arteriolar dilation is not known. We tested the hypothesis that ele...
