Urinary peptides across heart failure (HF) subtypes. (A) Comparison of the sequenced peptides that significantly differ between analysed sub‐groups. (B) Heat map presenting log2 transformed fold‐changes for 20 most significant peptides across HF subtypes and between all patients with HF in comparison to controls (Table  2 ). (C) Correlation of peptides significantly associated with HF with preserved (HFpEF), reduced (HFrEF) and mid‐range (HFmrEF) ejection fraction when comparing the fold‐change observed in HFpEF vs. controls, HFrEF vs. controls and HFmrEF vs. controls. Commonly significant peptides between comparisons were included.
