Incidence of clinical atrial fibrillation and related complications using a screening algorithm at a nationwide level
Authors' conclusion
These findings at a nationwide scale confirm the relevance of the subgroups in the EHRA algorithm for identifying a higher risk of AF incidence, showing that older patients (>75 years, regardless of comorbidities) have a higher incidence of AF than those with prior ischaemic stroke.
Study context
- Population
- Patients hospitalized in France in 2012 without a history of atrial fibrillation (AF), with ≥5-year follow-up (FU) (or earlier death)mean age 58.9 y, 64.5% women
- Participants
- 4,526 104 patients
- Exposure
- AF incidence across European Heart Rhythm Association (EHRA) screening algorithm risk groups
- Outcome
- Yearly incidence of AF
- Follow-up
- At least 5-year FU
Methodological detailsnationwide, French administrative hospital discharge database
- Nationwide
- French administrative hospital discharge database
