Background
Atrial fibrillation is often linked to weight, exercise, alcohol, sleep, blood pressure, and other modifiable risks. This review tested whether organized lifestyle clinics improve outcomes beyond usual care.
Patients
3364 adults with atrial fibrillation in 11 randomized trials; mean age 58 to 73 years, 30% female, 18% persistent atrial fibrillation. Excluded: nonrandomized studies and single-risk-factor interventions.
Intervention
Comprehensive lifestyle and risk factor clinics, mostly nurse-led, addressing education, weight, activity, alcohol, smoking, sleep apnea, blood pressure, and medicine adherence.
Control
Usual care, representing available current care in each trial.
Outcome
Primary: atrial rhythm recurrence. Secondary: hospitalizations, cardiovascular death, stroke or mini-stroke, and quality of life, including Short Form 36 Questionnaire (0 to 100; higher is better).
Follow-up Period
3 to 24 months.
Results
| Outcome | Population | Effect |
|---|---|---|
| Atrial rhythm recurrence (primary) | After ablation | OR 0.34 (95% CI 0.23 to 0.51) |
| Atrial fibrillation hospitalization | General population | OR 0.70 (95% CI 0.51 to 0.98) |
| Atrial fibrillation or heart failure hospitalization | General population | OR 0.74 (95% CI 0.59 to 0.91) |
| Quality of life | Short Form 36 trials | Mean difference 8.90 (95% CI 6.91 to 10.90) |
| Heart failure hospitalization; cardiovascular death; stroke or mini-stroke | Reported trial subsets | NS |
Absolute event rates were not pooled, so number needed to treat could not be calculated. The pooled hospitalization benefit was driven by atrial fibrillation-related admissions.
Limitations
Clinic models, duration, and outcomes varied. Participants may have been more motivated than typical patients. Few trials assessed death or stroke, limiting power. Possible small-study bias was detected for recurrence and heart failure hospitalization.
Funding
Scholarship support; no industry funding or disclosed conflicts.
Clinical Application
Refer suitable atrial fibrillation patients, especially after ablation, to structured lifestyle clinics; evidence supports fewer recurrences and admissions, not mortality benefit.
