Figure 1 Scatterplots showing the correlation between pulmonary capillary wedge pressure (PCWP) and log B-type natriuretic peptide (BNP) (top) and log N-terminal pro-B-type natriuretic peptide (NT-proBNP) (bottom) in the overall cohort. Values in parentheses indicate raw BNP and NT-proBNP values.

Figure 2 Bar graphs showing B-type natriuretic peptide (BNP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) values (top), and pulmonary capillary wedge pressure (PCWP), cardiac index (CI), and ejection fraction (EF) (bottom) in patients with an estimated glomerular filtration rate (eGFR) >60 ml/min and an eGFR <60 ml/min. Median values are shown in bold, with interquartile ranges shown in parentheses.
