| Population | AF group (aged 68.8 ± 7.0 years) n = 21 | AF/HF group (aged 67.3 ± 7.8 years) n = 24 | Drug therapy | Catheter ablation | Drug therapy | Catheter ablation |
| All | 9 | 12 | 8 | 16 | Females | 4 | 5 | 0 | 3 | Males | 5 | 7 | 8 | 13 | Mean time between randomization and catheter ablation to first interview (months) | 16.8 ± 11 | 28.3 ± 18.4 | Mean time between first and second interview (months) | 5.9 ± 2.3 | 5.7 ± 1.6 |
