Does the early development of atrial fibrillation during follow-up reduce survival in patients with idiopathic dilated cardiomyopathy?
In patients with idiopathic dilated cardiomyopathy, incident atrial fibrillation during follow-up is a marker of poor survival, whereas baseline atrial fibrillation is not.
Atrial fibrillation is relatively frequent in patients with IDCM. The early development of AF during follow-up, but not its presence at baseline, is associated with poor survival.
