Table 4.

Changes in reference values of NT-proBNP suggested by the ESC 2023 consensus document based on variations in eGFR and BMI.

eGFR (mL/min/1.73 m2)	Changes in reference values of NT-proBNP
eGFR < 30	Increase of 35%
30 ≤ eGFR < 45	Increase of 25%
45 ≤ eGFR < 60	Increase of 15%
BMI (kg/m2)	Changes in reference values of NT-proBNP
30 ≤ BMI < 35	Decrease of 25%
35 ≤ BMI < 40	Decrease of 30%
BMI ≥ 40	Decrease of 40%

Abbreviations: eGFR, estimated glomerular filtration rate; NT-proBNP, N-terminal pro-B-type natriuretic peptide; BMI, body mass index [12].
