    "abstract": "Adverse pregnancy outcomes, such as preterm delivery and hypertensive disorders of pregnancy, may be associated with higher future risks of heart failure (HF). However, the comparative effects of different adverse pregnancy outcomes on long-term risk of HF, and their potential causality, are unclear.\nThe authors sought to examine 5 major adverse pregnancy outcomes in relation to long-term risk of HF in a large population-based cohort.\nA national cohort study was conducted of all 2,201,638 women with a singleton delivery in Sweden in 1973-2015, followed up for HF identified from nationwide outpatient and inpatient diagnoses through 2018. Cox regression was used to compute HRs for HF associated with preterm delivery, small for gestational age, preeclampsia, other hypertensive disorders of pregnancy, and gestational diabetes, while adjusting for other adverse pregnancy outcomes and maternal factors. Co-sibling analyses assessed for potential confounding by shared familial (genetic or environmental) factors.\nIn 48 million person-years of follow-up, 667,774 women (30%) experienced an adverse pregnancy outcome, and 19,922 women (0.9%) were diagnosed with HF (median age, 61 years). All 5 adverse pregnancy outcomes were independently associated with long-term increased risk of HF. With up to 46 years of follow-up after delivery, adjusted HRs for HF associated with specific adverse pregnancy outcomes were: gestational diabetes, 2.19 (95%\u00a0CI: 1.95-2.45); preterm delivery, 1.68 (95%\u00a0CI: 1.61-1.75); other hypertensive disorders, 1.68 (95%\u00a0CI: 1.48-1.90); preeclampsia, 1.59 (95%\u00a0CI: 1.53-1.66); and small for gestational age, 1.35 (95%\u00a0CI: 1.31-1.40). All HRs remained significantly elevated (1.3- to 3.0-fold) even 30 to 46 years after delivery. These findings were only partially explained by shared familial factors. Women with multiple adverse pregnancy outcomes had further increases in risk (eg, up to 46 years after delivery, adjusted HRs associated with 1, 2, or\u00a0\u22653 adverse pregnancy outcomes were 1.51 [95%\u00a0CI: 1.47-1.56], 2.31 [95%\u00a0CI: 2.19-2.45], and 3.18 [95%\u00a0CI: 2.85-3.56], respectively).\nIn this large national cohort, women who experienced any of 5 major adverse pregnancy outcomes had increased risk for HF up to 46 years later. Women with adverse pregnancy outcomes need early preventive actions and long-term clinical care to reduce the risk of HF.",
