| Variable | LVEF | Regression coefficient* | Mathematical model** | References |
|---|---|---|---|---|
| ↑GLS | ↑↑ | +0.65/% | - | [6, 9, 27] |
| ↑mwCS | ↑↑↑ | +2.1/% | +3.2/% | [6, 9, 27] |
| ↑EDWT | ↑↑↑ | +2.1/mm | +2.6/mm | [3, 6, 27] |
| ↑LVIDd | ↓↓ | -0.42/mm | -1.2/mm | [6, 27] |

GLS, magnitude (absolute value) of global longitudinal strain; mwCS, magnitude of midwall circumferential strain; EDWT, end-diastolic wall thickness; LVIDd, left ventricular internal diameter in diastole; LV length, left ventricular internal long axis length in diastole
