Data are presented as mean ± SD. *P < 0.05 compared with HFpEF and HFrEF groups. E/DT: mitral peak early diastolic filling velocity to deceleration time ratio; E/e': mitral peak early diastolic filling velocity and early diastolic velocity by Doppler tissue imaging ratio; HFpEF: heart failure with preserved ejection fraction; HFrEF: heart failure with reduced ejection fraction; LVEDV: left ventricular end diastolic volume; LVEF: left ventricular ejection fraction; LVESV: left ventricular end systolic volume; LVIDd: diastolic left ventricular internal diameter; LVIDs: systolic left ventricular internal diameter; Mitral E wave: peak early diastolic filling velocity; TAPSE: tricuspid annular plane systolic excursion.
