BACKGROUND: The novel nonsteroidal mineralocorticoid receptor (MR) antagonist
finerenone holds promise to be safe and efficient in the treatment of patients
with heart failure and/or chronic kidney disease. However, its effects on
vascular function remain elusive. PURPOSE: The aim of this study was to determine
the functional effect of selective MR antagonism by finerenone in vascular cells
in vitro and the effect on vascular remodeling following acute vascular injury in
vivo. METHODS AND RESULTS: In vitro, finerenone dose-dependently reduced
aldosterone-induced smooth muscle cell (SMC) proliferation, as quantified by BrdU
incorporation, and prevented aldosterone-induced endothelial cell (EC) apoptosis,
as measured with a flow cytometry based caspase 3/7 activity assay. In vivo, oral
application of finerenone resulted in an accelerated re-endothelialization 3 days
following electric injury of the murine carotid artery. Furthermore, finerenone
treatment inhibited intimal and medial cell proliferation following wire-induced
injury of the murine femoral artery 10 days following injury and attenuated
neointimal lesion formation 21 days following injury. CONCLUSION: Finerenone
significantly reduces apoptosis of ECs and simultaneously attenuates SMC
proliferation, resulting in accelerated endothelial healing and reduced neointima
formation of the injured vessels. Thus, finerenone appears to provide favorable
vascular effects through restoring vascular integrity and preventing adverse
vascular remodeling.
