Key Takeaway

Consider cardiac rehabilitation to reduce atrial fibrillation recurrence (RR 0.77) and improve exercise capacity.

This meta-analysis synthesized data from randomized controlled trials involving 1550 patients with atrial fibrillation to evaluate the impact of cardiac rehabilitation (CR). The primary finding was a significant reduction in overall atrial fibrillation recurrence, reported as an RR 0.77 (95% CI [0.67-0.89], p = 0.0003). However, this reduction was not statistically significant in the specific subgroup of patients who underwent ablation (RR 0.86, 95% CI [0.69-1.07], p = 0.17).

Secondary outcomes showed that cardiac rehabilitation significantly improved exercise capacity as measured by a 6-minute walking test (WMD 32.22, 95% CI [21.22-43.23], p < 0.00001). In contrast, no significant differences were observed regarding all-cause mortality (RR 1.04), hospitalization rates (RR 1.00), or a composite outcome of mortality and hospitalization (RR 1.01).

The authors note that the evidence is limited by the need for more high-quality randomized trials to evaluate specific benefits and risks across different types of atrial fibrillation. Clinically, cardiac rehabilitation may be useful for improving exercise capacity and reducing recurrence in the general atrial fibrillation population, though its specific efficacy post-ablation remains uncertain.

How this fits prior evidence

This meta-analysis addresses a gap in understanding non-pharmacological interventions for atrial fibrillation management. While previous evidence highlights that left atrial appendage electrical isolation combined with pulmonary vein isolation reduces recurrent atrial arrhythmia, this study focuses on the role of cardiac rehabilitation. It confirms that CR improves exercise capacity and reduces recurrence in the general population, but it does not provide specific evidence regarding outcomes following procedures like pulsed field ablation or high-power short-duration ablation.

Researchers analyzed data from 1,550 patients with atrial fibrillation (AF) to see if cardiac rehabilitation programs could help manage the condition. The study looked at whether these programs reduced the chances of AF coming back, improved physical fitness, or lowered rates of hospitalization and death.

The results showed that cardiac rehabilitation was linked to a significant reduction in overall cases of AF recurrence. Patients also showed a measurable improvement in their exercise capacity during walking tests. However, the data did not show a statistically significant difference in recurrence for patients who had already undergone an ablation procedure.

While the program helped with heart rhythm and fitness, it did not show a significant impact on all-cause mortality or hospitalization rates. Because this was a meta-analysis of existing trials, more high-quality randomized studies are needed to fully understand the benefits and risks for different types of atrial fibrillation.

What this means for you:

Cardiac rehabilitation may reduce overall atrial fibrillation recurrence and improve exercise capacity in some patients.

Common questions

Can cardiac rehabilitation help prevent my heart rhythm from returning to an irregular state?

The study found a significant reduction in overall cases of atrial fibrillation recurrence among the 1,550 patients studied. However, this specific benefit was not found to be statistically significant for the subgroup of patients who had already undergone an ablation procedure.

Will cardiac rehabilitation improve my physical fitness?

Yes, the study reported a significant improvement in exercise capacity during 6-minute walking tests. This suggests that the program can help patients improve their ability to perform physical activities.

Does cardiac rehabilitation reduce hospital stays or death for heart patients?

The analysis did not find a significant difference in all-cause mortality, hospitalization rates, or a combination of both. These outcomes remained similar between those who received cardiac rehabilitation and the control groups.

BACKGROUND: Cardiac rehabilitation (CR) may benefit patients with atrial fibrillation (AF) in areas such as exercise capacity. However, evidence regarding its impact on AF recurrence, a key clinical outcome, remains inconsistent. This systematic review and meta-analysis of randomized controlled trials (RCTs) aimed to evaluate the effects of CR on AF recurrence, all-cause mortality, hospitalization, and exercise capacity in patients with AF. METHODS: We systematically searched the Cochrane Library, PubMed, and Embase from January 1, 1980, to April 20, 2026. Two reviewers independently screened studies, extracted data, and assessed risk of bias. A total of 1,550 patients from 11 RCTs were included in the meta-analysis based on the predefined inclusion and exclusion criteria. RESULTS: Pooled analysis demonstrated a significant reduction in AF recurrence among patients receiving CR compared with controls (risk ratio (RR) 0.77, 95% confidence interval (CI) [0.67-0.89], = 0.0003, = 20%). However, this effect was not statistically significant in the exploratory subgroup of patients post-ablation (RR 0.86, 95% CI [0.69-1.07], = 0.17, = 0%). Exercise capacity, measured via the 6-minute walking test, significantly improved (weighted mean difference (WMD) 32.22, 95% CI [21.22-43.23], < 0.00001, = 0%). No significant differences were observed in all-cause mortality (RR 1.04, 95% CI [0.74-1.46], = 0.81, = 0%), hospitalization rates (RR 1.00, 95% CI [0.85-1.19], = 0.97, = 0%), or the composite outcome of mortality and hospitalization (RR 1.01, 95% CI [0.90-1.14], = 0.83, = 0%). CONCLUSIONS: CR is associated with a reduction in AF recurrence in the overall AF population, though this benefit was not observed in the exploratory subgroup of patients post-ablation. It significantly improves exercise capacity but does not appear to affect mortality or hospitalization rates. Further high-quality randomized trials are needed to evaluate the benefits and potential risks of CR across different types of AF.
