Does symptomatic atrial fibrillation compared to asymptomatic atrial fibrillation affect the risk of major clinical outcomes in individuals with atrial fibrillation?
Symptomatic and asymptomatic atrial fibrillation carry similar risks for major clinical outcomes, though asymptomatic AF is associated with a higher risk of progression to permanent AF.
The risk of major clinical outcomes did not differ between individuals with and without AF-related symptoms. Asymptomatic patients had a greater hazard of progression to permanent AF.
