Coexisting atrial fibrillation and cancer: time trends and associations with mortality in a nationwide Dutch study
Authors' conclusion
Atrial fibrillation and cancer were associated bidirectionally and were increasingly coexisting, but AF risk varied by cancer type. Coexisting AF and cancer were negatively associated with survival.
Study context
- Population
- Dutch nationwide population with incident atrial fibrillation (AF) or cancer, 2015–19matched cohorts
- Participants
- 320,139 / 320,135 / 472,745 / 472,741
- Exposure
- Incident AF vs matched controls; incident cancer vs matched controls
- AFn = 320,139
- AF controlsn = 320,135reference
- Cancern = 472,745
- Cancer controlsn = 472,741reference
- Outcome
- Prevalence of cancer/AF at baseline, 1-year risk of cancer/AF diagnosis and time trends; association with all-cause mortality
- Follow-up
- 1 year
Methodological detailsmatched control cohorts, time-dependent Cox regression
- Matched control cohorts
- Time-dependent Cox regression
