| LV EF, % | 61 (56–68) | 58 (57–64) | 0.43 |
| Maximum LV wall thickness, mm | 9 (8–10) | 9 (8–9) | 0.84 |
| Regional LV WMA | 0 | 0 | ··· |
| RV EDV, mL/mq | 86 (74–93) | 82 (76–95) | 0.64 |
| RV EF, % | 55 (51–63) | 59 (57–67) | 0.38 |
| Regional RV WMA | 0 | 0 | ··· |
| LV myocardial edema | 0 | 0 | ··· |

Data are given as median (25th–75th percentile) or number (percentage). CMR indicates cardiac magnetic resonance; EDV, end‐diastolic volume; EF, ejection fraction; LGE, late gadolinium enhancement; LV, left ventricular; PVB, premature ventricular beat; RV, right ventricular; VA, ventricular arrhythmia; WMA, wall motion abnormality.
