Afferent renal denervation impairs baroreflex control of efferent renal sympathetic nerve activity.
Increasing efferent renal sympathetic nerve activity (ERSNA) increases afferent renal nerve activity (ARNA), which decreases ERSNA to prevent sodium retention. High-sodium diet enhances ARNA, suggesting an important role for ARNA in suppressing ERSNA during excess sodium intake. Mean arterial pressure (MAP) is elevated in afferent renal denervated by dorsal rhizotomy (DRX) rats fed high-sodium ...
متن کاملBlood pressure responses to renal denervation precede and are independent of the sympathetic and baroreflex effects.
It is still largely unknown whether the neuroadrenergic responses to renal denervation (RD) are involved in its blood pressure (BP)-lowering effects and represent predictors of the BP responses to RD. In 15 treated true resistant hypertensives, we measured before and 15 days, 1, 3, and 6 months after RD clinic, ambulatory and beat-to-beat BP. Measurements included muscle sympathetic nerve traff...

Renal Sympathetic Denervation: Renal Function Concerns To the Editor: We have read the report of the Simplicity HTN-1 investigators on the 2-year durability of blood pressure reduction induced by catheter-based renal sympathetic denervation with great excitement1 because it represents a promising approach for treatment of resistant hypertension.2 However, several concerns arise that require cla...
متن کاملRenal Sympathetic Denervation and Quality of Life
Background: Renal sympathetic denervation (RSD) is a promising strategy in the treatment of resistant hypertension. No studies have assessed the effect of RSD on quality of life in our country, which was the aim of this study. Methods: The EuroQol 5 Dimensions questionnaire (EQ 5D 5L) was chosen to evaluate quality of life in 10 patients undergoing RSD, and it was applied before and 3 months af...
متن کاملBaroreflex 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...
