Long-Term Risk of Heart Failure in Patients with Postoperative Atrial Fibrillation Following Non-Cardiac Surgery: Insights from a Nationwide Cohort
- Retrospective cohort study
- nationwide registries
- matched cohort (1:3)
Authors' conclusion
Patients with new-onset POAF following non-cardiac surgery had a higher associated long-term rate of incident HF compared to those without POAF, with no significant difference in the rate of incident HF when compared to patients with NVAF.
Study context
- Population
- Patients aged ≥30 years undergoing non-cardiac surgery, Danish nationwide registries, 1996–2020Postoperative AF (POAF) 2270 vs No POAF
- Exposure
- POAF vs No POAF vs non-valvular AF (NVAF)
- No POAFn = 6,810reference
- NVAFn = 5,538reference
- Outcome
- Long-term rate of incident heart failure (HF)
- Follow-up
- Median 7.2 years
