Probnp, N Terminal
N-terminal pro b-type natriuretic peptide (NT-proBNP) used to detect and evaluate heart failure. BNP is actually produced primarily by the left ventricle of the heart (the heart's main pumping chamber). It is associated with blood volume and pressure and with the work that the heart must do in pumping blood throughout the body.When the left ventricle of the heart is stretched, the concentrations of NT-proBNP produced can increase markedly. This situation indicates that the heart is working harder and having more trouble meeting the body's demands. This may occur with heart failure as well as with other diseases that affect the heart and circulatory system. It does not mean that the heart has stopped working; it just means that it is not pumping blood as effectively as it should be. NT-proBNP concentrations will reflect this diminished capacity.
