Brain Naturetic Peptide (or BNP for short)

BNP is a peptide first discovered in brain tissue, but which is predominanly released from the heart. Small amounts are needed to help regulate thirst and salt and water regulation.

When the heart either weakens or its chambers become 'pressure loaded' in heart failure, BNP is released into the blood stream where is can be measured by a simple blood test.

This phenomenon means that in patients reporting symptoms of heart failure such as breathlessness, fatigue and/ or ankle swelling your GP can test the blood for BNP in order to screen for heart failure.
