CS was positively correlated with BNP (r = 0.355), sST2 (r = 0.290), left atrial size (r = 0.317), LVDD (r = 0.187), peak tricuspid regurgitation velocity > 2.8 m/s (r = 0.235), and E/e′ (r = 0.371), and negatively correlated with LVEF (r = − 0.243). Here, NPPB is linked to tricuspid valve insufficiency.
