Distinct contributions of skin and core temperatures to flow-mediated dilation of the brachial artery following passive heating
نویسندگان
چکیده
The primary determinant of vascular adaptations to lifestyle interventions, such as exercise and heat therapy, is repeated elevations in shear stress. Whether skin or core temperatures also modulate the adaptation acute exposure unknown, likely due difficulty dissociating thermal hemodynamic responses heat. We found that modify passive heating irrespective magnitude increase

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 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 Following Exercise with Augmented Oscillatory and Retrograde Shear Rate
BACKGROUND Acute doses of elevated retrograde shear rate (SR) appear to be detrimental to endothelial function in resting humans. However, retrograde shear increases during moderate intensity exercise which also enhances post-exercise endothelial function. Since SR patterns differ with the modality of exercise, it is important to determine if augmented retrograde SR during exercise influences p...
متن کاملCan the measurement of brachial artery flow-mediated dilation be applied to the acute exercise model?
The measurement of flow-mediated dilation using high-resolution ultrasound has been utilized extensively in interventional trials evaluating the salutary effect of drugs and lifestyle modifications (i.e. diet or exercise training) on endothelial function; however, until recently researchers have not used flow-mediated dilation to examine the role of a single bout of exercise on vascular functio...
متن کاملReliability of the measurement of the flow-mediated dilation of the brachial artery by ultrasonography.
E-mail: [email protected] Senhor Editor, Lemos com muito interesse o trabalho de Meirelles e cols.1 sobre a confiabilidade da medida da dilatação fluxo-mediada da artéria braquial por meio da ultra-sonografia realizada em 13 voluntários aparentemente saudáveis e não fumantes. Neste trabalho, os autores tiveram o cuidado de utilizar a metodologia padronizada e as recomendações da Internationa...
