Reactive Hyperemia in Legs of Dogs: Effects of Temperature and Intravascular Tension.
• After observing that reactive hyperemia (RH) in the human forearm increased in duration and magnitude as the preceding period of arterial occlusion was prolonged, Lewis and Grant suggested that this stasis vasodilatation resulted from progressive accumulation of "normal products of tissue metabolism . . . which are removed normally as fast as they are formed." Although indirect evidence of su...
متن کاملReduction of myocardial reactive hyperemia during oxygen breathing in dogs.
In 7 open-chest anesthetized mongrel dogs the left anterior descending coronary artery was occluded for 20 sec. Myocardial reactive hyperemia was recorded during air and oxygen breathings. The excess blood flow during the reactive hyperemia was smaller and the duration of the reactive hyperemia was shorter during oxygen breathing than during air breathing. It is suggested that the reduction of ...
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 کاملReactive 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 کاملDemonstration of Myocardial Reactive Hyperemia in Man
one subject with isolated, fixed coronary obstruction. Three subjects with variant angina had short episodes of ischemic ST-segment elevation that lasted 20-100 seconds. Thallium scintigrams demonstrated excess uptake in regions judged to be ischemic by angiographic and electrocardiographic criteria. Two subjects, one with variant angina and the other with a fixed coronary lesion, had prolonged...
