Performance of echocardiographic parameters to predict all-cause mortality
| Parameter | Cut-off value | Sensitivity (%) | Specificity (%) | PPV (%) | NPV (%) |
| LVEF | 52% | 58 | 56 | 28 | 82 |
| MCF | 15% | 64 | 44 | 72 | 72 |
| GLS | −10% | 65 | 49 | 29 | 81 |
| GWI | 937 mm Hg/% | 65 | 48 | 29 | 81 |
| GWE | 89% | 64 | 81 | 35 | 87 |
GLS, global longitudinal strain; GWE, global work efficiency; GWI, global work index; LVEF, left ventricular ejection fraction; MCF, myocardial contraction fraction; NPV, negative predictive value; PPV, positive predictive value.
