Atrial Fibrillation, Catheter Ablation, Heart Failure, Rate Control
Conditions
Brief summary
To evaluate the efficacy of catheter ablation and rate control in heart failure patients with atrial fibrillation.
Detailed description
All patients received either catheter ablation for rhythm control or rate control before enrollment, and the investigators do not assign specific interventions to the subjects during the study. So this study might be considered to be observational.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Major adverse cardiac events | up to 3 years | composite of all-cause mortality, stroke and unplanned hospitalization due to cardiovascular reasons |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| all-cause mortality | up to 3 years | — |
| stroke | up to 3 years | stroke must be certified by CT scan |
| unplanned hospitalization due to cardiovascular reasons | up to 3 years | Unplanned hospitalization will be present only if the patient is hospitalized unexpectedly because of persisting or increasing complaints of heart failure and ventricular arrhythmias |
