Abstract
Background: The long-term effects of catheter ablation (CA) compared with medical therapy on cardiovascular outcomes for atrial fibrillation (AF) remain undetermined.
Objective: Using a population-based cohort, we sought to determine what the association between CA and medical therapy was on these outcomes.
Methods: By use of Alberta administrative data, patients with AF as the primary diagnosis during hospitalization, emergency department visit, or physician visit were included between October 1, 2008, and March 31, 2018. Based on therapy received, patients were assigned to categories of CA, rate control, or rhythm control with medication. The association of treatment with the primary composite outcome of all-cause death, hospitalization for heart failure, or stroke was examined after adjustment for age, sex, comorbidities, and baseline medications.
Results: Of 39,966 treated AF patients, 2077 (5.2%), 29,467 (73.7%), and 8422 (21.1%) were treated with CA, rate control, and rhythm control with medication, respectively. Patients in the CA group had a lower incidence of the primary outcome (4.0/100 person-years) compared with the rate control group (8.7/100 person-years) or the rhythm control with medication group (6.8/100 person-years) during a median follow-up of 6.3 years. In multivariable analysis, compared with CA, both rate control (hazard ratio, 1.28; 95% confidence interval, 1.09-1.50) and rhythm control with medication (hazard ratio, 1.21; 95% confidence interval, 1.03-1.43) were associated with a higher risk of the primary outcome.
Conclusion: In this cohort study, patients who received CA demonstrated a reduction in the risk of long-term adverse cardiovascular outcomes compared with medical therapy in patients with AF, providing some data to indicate the effects of CA in the long-term.
