Temporal trends of cause-specific mortality after diagnosis of atrial fibrillation
Authors' conclusion
After AF diagnosis, cardio/cerebrovascular mortality and hospitalization has declined, whilst hospitalization for non-cardio/cerebrovascular disease has increased.

Event rates by patient features
- Older, more deprived and hospital-diagnosed AF patients experienced higher event rates
