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 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 کاملCerebral hyperemia in MELAS.
BACKGROUND The pathophysiology of stroke-like episodes in MELAS (mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes) is uncertain. CASE DESCRIPTION We studied a 24-year-old man with MELAS who had fluent aphasia and right hemianopia. Magnetic resonance imaging and computed tomography showed a large infarction in the parietal, temporal, and occipital lobes. We performed ...
متن کاملCerebral ischemia and reactive hyperemia. Studies of cortical blood flow and microcirculation before, during, and after temporary occlusion of middle cerebral artery of squirrel monkeys.
Correlative studies of cortical blood flow measured by the Kr washout technique and observations of the cortical blood vessels of 10 squirrel monkeys subjected to temporary occlusion of the middle cerebral artery are described. During occlusion, cortical blood flow in core areas of ischemia decreased to 0.12 to 0.90 ml/g/min (20 to 50% of preocclusion values) and became pressure dependent with ...
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...
