Other: Usual Care -


Other interventions: Early atrial fibrillation ablation
Patients randomised to early atrial fibrillation ablation will undergo pulmonary vein isolation within 2 months after randomisation.

Other interventions: Usual Care
Usual care will consist of optimal AF therapy based on guideline recommendations and local protocols and usage.The choice of therapies and medications follows routine care in line with medical guidelines and local policies at the discretion of the treating physician and should be based on the individual medical status of each study patient.

Summary
Brief summary
EASThigh-AFNET 11 is an international, prospective, randomized, open, blinded endpoint
assessment, multicenter trial (Treatment Strategy trial).

The objective of EASThigh-AFNET 11 is to investigate whether early atrial fibrillation
ablation in patients with atrial fibrillation (AF) and a high comorbidity burden
(CHA2DS2-VASc =4) reduces cardiovascular events (stroke, cardiovascular death, or heart
failure events) compared to usual care.
