Relationships between the concentrations of biomarkers in pericardial fluid (in blue) and venous plasma (in red) of cardiovascular disease patients.

Statistically significant correlations between continuous variables are indicated by Spearman correlation coefficient and *, p < 0.05; **, p < 0.01 and ***, p < 0.001. Peptides and proteins are ordered (left to right and top to bottom) according to the molecular weight of their reported most abundant soluble oligomer. N = 139–152. NT-pBNP, N-terminal pro-brain natriuretic peptide; FABP4, fatty acid-binding protein 4; Lcn2, lipocalin-2; NE, neutrophil elastase; Prot3, proteinase-3; hsCRP, high sensitivity C-reactive protein; APN, adiponectin; —, not statistically significant.
