| LA max (ml) | 67.0 ± 20.0 |
| LA max, indexed (ml/m2) | 35.9 ± 10.0 |
| LA min (ml) | 26.0 (19.9–33.6) |
| LA min, indexed (ml/m2) | 14.1 (10.9–17.9) |

Continuous variables are presented as mean ± SD, skewed variables (defined as -1 < skewness >1) as median (IQR min – IQR max) and binary variables as percentages. LA volumes were measured using the biplane method. BMI, denotes body mass index; LA, left atrium; SV, stroke volume; EF, ejection fraction; BSA, body surface area.
