Reactive hyperemia and cardiovascular risk.
Since the description of the classical cardiovascular risk factors by the Framingham group some 50 years ago,1 more recent efforts have explored the utility of biomarkers to further refine risk stratification. Although vascular imaging and biochemical markers have shown considerable promise,2 assessment of vascular function has particular appeal. Endothelial dysfunction is an attendant feature ...
متن کاملShort duration of reactive hyperemia in the forearm of subjects with multiple cardiovascular risk factors.
BACKGROUND Peripheral vascular endothelial dysfunction is an independent predictor of cardiovascular events, and can be assessed noninvasively by measuring reactive hyperemia, either by vascular ultrasound measurement of flow-mediated vasodilatation or, less commonly, by measurement of blood flow using plethysmography. In the present study reactive hyperemia was measured using plethysmography i...
متن کاملReactive hyperemia revisited.
To the Editor: We read with great interest Dr Huang’s study, published in Arteriosclerosis, Thrombosis, and Vascular Biology.1 We are in total agreement with the authors about the clinical relevance in the perioperative setting of the hyperemic flow velocity, measured by brachial artery Doppler ultrasound. Dr Huang suggests that reactive hyperemia increases the accuracy of the noninvasive vascu...
متن کاملConway Reactive Hyperemia Resistance and Blood Pressure
T HE increased peripheral resistance associated with hypertension has been demonstrated for the circulation as a whole by measurements of blood pressure and cardiac output.l 2 The site of this resistance has not been precisely identified but it is believed to reside in the smallest arteries and arterioles.3'4 Since the activity of the smooth muscle in these vessels is readily affected by humora...
متن کاملReactive Hyperemia in Human Forearm Vessels
Background The role of nitric oxide (NO) in reactive hyperemia (RH) is not well known. We investigated whether NO plays a role in RH in human forearm vessels by examining the effects of N0-monomethyl-L-arginine (L-NMMA), a blocker of NO synthesis, on reactive hyperemic flow. Methods and Results Forearm blood flow (FBF) was measured by strain-gauge plethysmography with a venous occlusion techniq...
