  • * Significance set at p < 0.05. LVEF: left ventricle ejection fraction; E: early diastolic filling velocity; E’: early diastolic filling wave on tissue Doppler imaging; GLS: global longitudinal strain; TAPSE: tricuspidal annulus plane systolic excursion; FAC: fractional area change; S’: peak systolic annular velocity on tissue Doppler imaging; A: late diastolic filling velocity; NS: not significant.
