Pre-existing AF does not independently raise 30-day ATE or mortality risk in pneumonia hospitalizations; leaves open its prognostic role in other acute settings.
Does pre-existing atrial fibrillation independently increase the risk of arterial thromboembolism and death in patients hospitalized with pneumonia?
In patients hospitalized with pneumonia, the higher crude rates of arterial thromboembolism and death observed in those with pre-existing atrial fibrillation are explained by older age and comorbidities rather than the arrhythmia itself.
