Key result
Renal denervation significantly decreased aldosterone levels and reduced AT1R mRNA expression by 2.22-fold compared to sham operation in spontaneously hypertensive rats (p < 0.05).
Why the study?
The study was conducted to explore the effect of renal denervation on the renin-angiotensin-aldosterone system in spontaneously hypertensive rats.
Does renal denervation inhibit the renin-angiotensin-aldosterone system in spontaneously hypertensive rats?

Does renal denervation inhibit the renin-angiotensin-aldosterone system in spontaneously hypertensive rats?
Effect estimate: reduced by 2.22-fold (AT1R mRNA)
p-value: p=< .05
Renal denervation reduces intrarenal and circulating RAAS components in spontaneously hypertensive rats, providing a mechanistic basis for its blood pressure-lowering effects.
No takes yet. Share an insight, caveat, or question.
RDN effects on RAAS in rats warrant human mechanistic studies; leaves open clinical relevance in hypertension.
Qin et al. (2021) conducted an RCT in Hypertension (spontaneously hypertensive rats). Renal denervation (RDN) vs. Sham operation (saline) and normotension control (WKY) was evaluated on Aldosterone levels and expression of AT1R mRNA/protein and Ang II protein (reduced by 2.22-fold (AT1R mRNA), p=< .05). Renal denervation significantly decreased aldosterone levels and reduced AT1R mRNA expression by 2.22-fold compared to sham operation in spontaneously hypertensive rats (p < 0.05).
