Effects of finerenone on renal hemodynamics and oxidative stress

The main goal of this mechanistic, prospective, double-blind, placebo controlled, randomized study is to demonstrate the effect of finerenone on the oxidative stress of renal vasculature. Moreover, parameters of renal hemodynamics like renal plasma flow, total renal vascular resistance, filtration fraction, parameters of intraglomerular hemodynamics etc. are analyzed in detail. Finally, the change in renal nitric oxide activity with finerenone treatment is analyzed. The primary objective of this mechanistic study is to analyse: \- the impact of finerenone on the oxidative stress level of renal vasculature by the increase of renal perfusion following vitamin C infusion compared to placebo
