Heart failure with preserved ejection fraction (HFpEF) is one of the most rapidly growing cardiovascular health burden worldwide, but there is still a lack of understanding about the HFpEF pathophysiology. The nitric oxide (NO) signalling pathway has been identified as a potential key element. The aim of our study was to investigate markers of NO metabolism [l‐arginine (l‐Arg), homoarginine (hArg), and asymmetric and symmetric dimethylarginine (ADMA and SDMA)], additional biomarkers [N‐terminal pro‐B‐type natriuretic peptide (NT‐proBNP), endothelin‐1 (ET‐1), mid‐regional pro‐adrenomedullin (MR‐proADM), copeptin, and high‐sensitivity C‐reactive protein (hsCRP)], and the endothelial function in an integrated approach focusing on associations with clinical characteristics in patients with HFpEF.
