Arrhythmias & electrophysiology
Social determinants of health and recurrence of atrial fibrillation after catheter ablation: a Danish nationwide cohort study
Authors' conclusion
AF was more likely to recur among patients with lower educational attainment, lower family income, or those living alone.
Study context
- Population
- Patients undergoing first AF ablation after incident hospital AF diagnosis, Denmark, 2005–2018mean age 61 years, 70% men
- Participants
- 9,728 patients
- Exposure
- Lower or medium education, lower or medium income, living alone vs higher education, higher income, not living alone
- Outcome
- Recurrence of AF after ablation
Methodological detailsDanish nationwide registry
- Danish nationwide registry
Main finding
As reported in the abstract
AF recurrence · average 1.37 years after ablation
Hazard ratio (95% CI)
Lower educationvs Higher education
1.09(1.02–1.17)
Medium educationvs Higher education
1.07(1.01–1.14)
Lower incomevs Higher income
1.14(1.06–1.22)
Medium incomevs Higher income
1.09(1.03–1.17)
Living alone
1.07(1.00–1.13)
- AF recurrence in 5881 patients; recurrence rate per 1000 person-years
- 325.7 (95% CI 317.6-334.2)
Observational data: associations, not effects.
Further findings
Interaction of sex or prior HF with social determinants of health (SDOH)
- No evidence of interaction between sex or prior HF with SDOH
Income and AF recurrence, by age (subgroup)
- Association stronger among patients < 65 years than ≥ 65 years
SDOH and AF recurrence, multivariable model (adjusted for comorbidities, antiarrhythmic medication, prior electrical cardioversion)
- Associations did not persist
