NT-proBNP
NT-proBNP is a protein fragment released by the heart muscle when the walls of its chambers are stretched.
NT-proBNP is a protein fragment released by the heart muscle when the walls of its chambers are stretched. The more the heart works against pressure and volume, the more is released, so the level reflects the workload on the heart. It is one of the blood values that relate to heart and blood vessel health.
Levels rise naturally with age and are usually somewhat higher in women. How well the kidneys clear the protein, hard endurance exercise in the days before the test, body weight and some medicines also play a part.
