What are BNP and NT proBNP tests? Cardiology Basics

BNP and NT-proBNP tests are used for detection of heart failure. When the heart fails, there is stretching of the ventricles which leads to release of BNP from the myocardium. Pro BNP is the precursor of BNP, which is cleaved by enzymes to NT-proBNP and BNP. BNP stands for brain natriuretic peptide or B-type natriuretic peptide. BNP is biologically active while NT-proBNP is not.
Will you estimate BNP or NT-pro BNP in those on ARNI? Is there any limitation for BNP and NT-proBNP in obesity?
