All LV strain and torsional indices in the heart failure patients were lower than that of the control group (p<0.05): Global longitudinal strain (GLS), twist in the heart failure group was - 11.01 ± 3.82s-1 and 7.94 ± 4.28 degrees; in the control group were - 19.92 ± 2.87s-1 and 16.83 ± 9.87 degrees; In the heart failure group, EF ≥ 50% was - 14.25s-1 ± 4.35 and 10.96 ± 4.74 degrees.
