Baroreflex sensitivity in renal failure
1. Baroreflex sensitivity was evaluated in 22 non-dialysed patients with chronic renal failure secondary to chronic glomerulonephritis. Baroreflex sensitivity was judged by the slope of the linear regression of the pulse interval on the rise in systolic blood pressure with injection of phenylephrine or reduction by amyl nitrite inhalation. 2. Baroreflex sensitivity was reduced in these patients...
متن کاملBaroreflex sensitivity in hypertension during beta-adrenergic blockade.
Baroreceptor function was measured in 18 patients with essential hypertension by plotting the change in pulse interval against a phenylephrine-induced transient rise in systolic blood pressure. The influence of propranolol (160 mg daily for at least 4 weeks) on this function and on heart rate after maximal exercise was studied and correlated with the plasma propranolol level. In 13 out of the 1...
متن کاملAdrenergic Mediation of Hypoglycemia-Associated Autonomic Failure
OBJECTIVE We tested the hypothesis that adrenergic activation, cholinergic activation, or both, mediate the effect of recent antecedent hypoglycemia to reduce the sympathoadrenal response to subsequent hypoglycemia, the key feature of hypoglycemia-associated autonomic failure in diabetes, in humans. RESEARCH DESIGN AND METHODS Seventeen healthy adults were studied on 2 consecutive days on thr...
متن کاملBaroreflex sensitivity and oxidative stress in adriamycin-induced heart failure.
Adriamycin cardiotoxicity is associated with oxidative stress in the presence of globally depressed cardiac function. It is unknown if there is a similar profile with early diastolic changes and how it relates to baroreflex control of circulation. In this study, we evaluated baroreflex control of circulation in adriamycin-treated Wistar rats compared with controls, using invasive blood pressure...
متن کاملCardiovascular baroreflex sensitivity attenuates by cisplatin-induced toxicity in rats
Introduction: Cisplatin (CP) therapy may disturb cardiovascular system control. The objective of this study was to find baroreflex sensitivity (BRS) in CP-induced nephrotoxicity in rats. Materials and Methods: Eighteen male and female Wistar rats were randomly assigned to two groups treated with CP (2.5 mg/kg/day) and the vehicle, for five consecutive days, and then were subjected to surgical ...
