According the the Cleveland Clinic website article titled, “B-type Natriuretic Peptide (BNP) Blood Test“, the BNP is defined as “a substance secreted from the ventricles or lower chambers of the heart in response to changes in pressure that occur when heart failure develops and worsens. The level of BNP in the blood increases when heart failure symptoms worsen, and decreases when the heart failure condition is stable. The BNP level in a person with heart failure – even someone whose condition is stable – is higher than in a person with normal heart function.”[http://my.clevelandclinic.org/heart/diagnostics-testing/laboratory-tests/b-type-natriuretic-peptide-bnp-bloodtest.aspx]
According the the Cleveland Clinic website article titled, “Blood Tests to Determine Risk of Coronary Artery Disease“, the N-terminal-pro-B-type Natriuretic Peptide (NT-proBNP) is defined as, “Non-traditional” blood protein made in the heart and found in the blood. High levels are associated with increased risks of cardiovascular disease, heart attack and heart failure development. Elevated levels are associated with development of heart failure and worse prognosis.”[http://my.clevelandclinic.org/heart/diagnostics-testing/laboratory-tests/blood-tests-to-determine-risk-of-coronary-artery-disease.aspx]
