Polygenic risk scores enhance prediction of atrial fibrillation disease progression: An analysis of the UK Biobank

Heart RhythmPublished

  • analysis of the UK Biobank
  • multivariable Cox regression

Authors' conclusion

AF polygenic risk independently predicts progression from paroxysmal to persistent AF and enhances risk stratification beyond clinical factors.

Study context

Population
Individuals with paroxysmal atrial fibrillation (AF) (based on International Classification of Diseases, 10th Revision, coding) in the UK Biobankindividuals with paroxysmal AF (median age at diagnosis 73 years, 47% women)
Participants
7,128 individuals
Comparison
AF-PRS tertiles, after adjustment for clinical risk factors
Outcome
Time to AF progression (ICD-10 diagnosis of chronic or persistent AF, or requirement for electrical cardioversion)
Follow-up
Median 3.0 years

Main finding
