Exploring the role of iNOS in HFpEF-Related myocardial fibrosis: Involvement of PTEN-PI3K/AKT signaling pathway

Heart failure with preserved ejection fraction (HFpEF) is a challenging condition to treat with myocardial fibrosis being a pivotal pathological component. Previous studies have suggested a role for inducible nitric oxide synthase (iNOS) in the progression of this condition, but the precise mechanisms remain unclear. This study aimed to investigate the role of iNOS in HFpEF-related myocardial fibrosis and identify potential therapeutic targets.
