NPPB and tricuspid valve insufficiency: NT-proBNP is an indicator of cardiac congestion [31] and in our cohort it was associated with higher left ventricular end-diastolic and end-systolic volumes (LVesDiam p = 0.048 and LVedDiam p = 0.050) and a higher degree of mitral, aortic and tricuspid valve insufficiency (MI p = 0.012, AI p = 0.001, TI = 0.037, respectively).
