Comparison of Parameters of Long Axial Strain and Left Ventricular Myocardial Work in Each Group (x ± S)
| Group | No. | GLS (%) | GWI (mmHg%) | GCW (mmHg%) | GWW (mmHg%) | GWE (%) |
|---|---|---|---|---|---|---|
| Control group | 30 | −21.0±1.6 | 2040±193 | 2359±194 | 64±28 | 96.5±1.1 |
| M0 group | 50 | −20.1±1.4 | 2029±165 | 2339±207 | 67±22 | 96.7±0.9 |
| M3 group | 50 | −17.5±2.8 | 1831±301 | 1962±340 | 84±26 | 93.4±2.1 |
| P* | >0.05 | >0.05 | >0.05 | >0.05 | >0.05 | |
| P# | <0.001 | <0.001 | <0.001 | 0.450 | <0.001 |
Notes: GLS is the overall longitudinal peak strain, GWI is the overall work index, GCW is the overall effective work, GWW is the overall ineffective work, GWE is the overall work efficiency; GLS minus sign indicates direction; Compared with control group, *P<0.05; Compared with the group before chemotherapy, #P<0.05.
