Latent class analysis-derived patterns of comorbidities in patients with atrial fibrillation, adherence to integrated care and impact on long-term outcomes: an analysis from a prospective cohort

Heart RhythmPublished prospective cohort

Authors' conclusion

Latent class analysis identified distinct AF clinical phenotypes characterized by specific patterns of comorbidities and associated with different risk of adverse outcomes. The absence of significant heterogeneity in the association between integrated care and outcomes across phenotypes supports its potential value across different levels of clinical complexity in AF patients.

Study context

Population
Patients with atrial fibrillation (AF)AF patients included (median age 75 [66–82] years, females 37.5%)

Outcome
Composite of:
  • All-cause death
  • Thromboembolic (TE) events
  • Acute coronary syndrome (ACS)
Follow-up
Median 542 days
Methodological detailslatent class analysis
  • Latent class analysis

Main finding

As reported in the abstract

  • Acute coronary syndrome (ACS)
Each group vs low comorbidityAdjusted hazard ratio (95% CI)
Cardio-metabolic

Elderly comorbid
1.62(1.09–2.42)

Observational data: associations, not effects.

Secondary outcomes

Distribution of LCA-derived phenotypes

Adherence to integrated care and adverse events across phenotypes

Adherence to integrated care varied across phenotypes and was associated with a lower risk of adverse events
  • No evidence of significant heterogeneity across phenotypes (p int=0.157)
