ANP vs. BNP: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on February 7, 2024
ANP (Atrial Natriuretic Peptide) is a hormone regulating blood pressure and fluid balance, while BNP (Brain Natriuretic Peptide) primarily indicates heart stress and is used to diagnose heart failure.

Key Differences

ANP is a hormone produced by the atria of the heart, playing a crucial role in reducing blood pressure and controlling fluid balance. BNP, however, is mainly released from the ventricles and is a biomarker for cardiac stress and heart failure diagnosis.

The primary function of ANP is to lower blood volume and pressure by increasing sodium and water excretion. In contrast, BNP is elevated in patients with congestive heart failure, as it responds to excessive stretching of heart muscle.

ANP achieves its effects by dilating blood vessels and inhibiting the release of stress hormones like adrenaline. BNP, meanwhile, is used clinically to guide heart failure treatment, as its levels correlate with the severity of the condition.

Both ANP and BNP are part of the body's response to heart and circulatory system stress but differ in their specific roles and production sites. ANP is more involved in everyday regulation of blood pressure, whereas BNP serves as a critical indicator of acute cardiac distress.

In medical practice, ANP levels are less commonly measured than BNP levels, which are a routine part of heart failure evaluation and management.
