LVEDVI, left ventricular end-diastolic volume index; mPCW, mean pulmonary
capillary wedge pressure; LVEDP, left ventricular end-diastolic pressure; t,
time constant of left ventricular relaxation;
b, constant of left ventricular
chamber stiffness; TD, tissue Doppler; E, early mitral valve flow velocity; E0,
early TD lengthening velocity; NT-proBNP, N-terminal-pro brain natriuretic
peptide; BNP, brain natriuretic peptide; E/A, ratio of early (E) to late (A)
mitral valve flow velocity; DT, deceleration time; LVMI, left ventricular mass
index; LAVI, left atrial volume index; Ard, duration of reverse pulmonary
vein atrial systole flow; Ad, duration of mitral valve atrial wave flow.
