Key result
High-dose simvastatin normalized renal sympathetic nerve activity in rabbits with pacing-induced chronic heart failure (21.1% vs 39.4% in CHF controls).

Does not support statin use for autonomic modulation in heart failure; leaves open pleiotropic mechanisms for clinical investigation.
Does simvastatin improve autonomic neural control in an experimental rabbit model of heart failure?
Absolute Event Rate: 21.1% vs 39.4%
High-dose simvastatin normalizes sympathetic outflow and reflex regulation in an experimental rabbit model of heart failure, suggesting a non-lipid-lowering mechanism for statin benefits in CHF.
Pliquett et al. (2003) studied Chronic heart failure (experimental). Simvastatin vs. Vehicle (CHF controls) was evaluated on Mean baseline renal sympathetic nerve activity (RSNA). High-dose simvastatin normalized renal sympathetic nerve activity in rabbits with pacing-induced chronic heart failure (21.1% vs 39.4% in CHF controls).
