Patients with atrial fibrillation (AF) and a history of stroke are at high risk of recurrent stroke and cardiovascular complications. A subgroup analysis of the EAST – AFNET 4 trial showed: Early rhythm control therapy is safe and particularly effective in this vulnerable patient group. The results were presented at the World Stroke Congress in Singapore on 26.10.2022 [1], [2].
The EAST – AFNET 4 (Early Treatment of Atrial Fibrillation for Stroke Prevention) trial investigated whether rhythm control therapy – using antiarrhythmic drugs or atrial fibrillation ablation – delivered within one year after AF diagnosis improves outcomes. The main study result, published in 2020 [3], demonstrated that early rhythm control therapy reduced cardiovascular events by 21% in patients with AF and comorbidities: Early rhythm control (ERC) with antiarrhythmic drugs and/or AF ablation reduced the primary outcome, a composite of cardiovascular death, stroke, and hospitalization for worsening heart failure or acute coronary syndrome, in 2789 patients with early AF and cardiovascular risk factors compared to usual care (UC) over a 5-year follow-up time.
