Diurnal Variations in Natriuretic Peptide Levels: Clinical Implications for the Diagnosis of Acute Heart Failure

This study hypothesized that diurnal variations in NP concentration might affect their diagnostic accuracy for acute heart failure. Among patients adjudicated to have acute heart failure, BNP, NT-proBNP, and MR-proANP concentrations were comparable among daytime versus evening/nighttime presenters. These differences were not observed for MR-proANP. Diurnal variation of BNP and NT-proBNP with lower evening/nighttime concentration was confirmed in 44 stable individuals (P<0.01). BNP and NT-proBNP, but not MR-proANP, exhibit a daily rhythm that results in even higher diagnostic accuracy among evening/nighttime presenters versus daytime presenters.
