Correlation between NT-proBNP and Doppler echocardiographic parameters

^*p < 0.05. r: pearson's correlation coefficient. NT-proBNP: N-terminal pro-brain natriuretic, peptide, LVEDD: left ventricular end-diastolic dimension, LA: left atrium, LVOT TVI: left ventricular outflow track time velocity integral, RVSP: right ventricular systolic pressure, PVs: pulmonary vein systolic velocity, PVd: pulmonary vein diastolic velocity, PVs/PVd: ratio of PVs/PVd, E' (average mitral annulus) (m/sec): The average E' of both septal mitral annulus and lateral mitral annulus, E/E': ratio of mitral E-veolicty and mitral annular E' velocity, E/E'(average mitral annulus): ratio of mitral E-velocity and average E'
