Key result
Stopping diuretics and saline hydration normalizes dehydration-induced natriuretic peptide elevation.
Why the study?
Natriuretic peptide levels can be elevated due to dehydration even in the absence of renal impairment, which may confound heart failure assessment.
Case Report (n=1)
Dehydration can cause elevated natriuretic peptide levels even in the absence of renal impairment, which can be reversed with hydration and stopping diuretics.

May warrant assessing volume status before attributing natriuretic peptide elevation to heart failure; leaves open validation in larger cohorts.
B-type natriuretic peptide is secreted primarily by cardiomyocytes in response to increased ventricular or atrial wall stress reflecting volume or pressure overload. The relationship between natriuretic peptides and the severity of heart failure is well established. We present here a case where natriuretic peptide levels were increased due to dehydration in the abscence of renal impairment. Normalization of natriuretic peptide level was achieved by stopping the diuretics and the administration of normal saline.

Alzand et al. (2011) conducted a case report in Dehydration (n=1). Stopping diuretics and administration of normal saline was evaluated on Normalization of natriuretic peptide level. Stopping diuretics and administering normal saline normalized elevated natriuretic peptide levels caused by dehydration in a patient without renal impairment.
