Adverse pregnancy outcomes and risk of atrial fibrillation: findings from the HUNT study
Authors' conclusion
Women with history of HDP or LGA offspring are at higher risk of AF.

HDPwomen aged 45-65
2.03(1.27–3.24)
HDPwomen >65 years

Observational data: associations, not effects.
Further findings
Mediation by post-pregnancy BMI (inverse odds ratio weighting)
- Post-pregnancy BMI might possibly explain share of hypertensive disorders of pregnancy (HDP)/LGA–atrial fibrillation (AF) associations
- ∼45%
