A Systematic Review of Complications Following Pre-eclampsia

IntroductionMost pregnancies are low-risk. However, sometimes women develop pre-eclampsia. The incidence varies based on different studies (Havers-Borgersen et al., 2023, 10.1136/jech-2023-220829).Pre-eclampsia is characterized by elevated blood pressure, protein in the urine, and excessive swelling and occurs after 20 weeks of pregnancy though in the case of severe symptoms, all may not be required for diagnosis (Bajpai et al., 2023). Many strategies exist to identify women with pre-eclampsia and to treat it. There are known immediate risks to both the mother and fetus. Some of these risks extend beyond the immediate postpartum period. Much less is known regarding the long-term risks. Therefore, the purpose of our study was to conduct a systematic review of the long-term complications related to pre-eclampsia.MethodsThe Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) were used to guide this systematic review. PubMed, CINAHL, Medline, Scopus, PschINFO, and Google Scholar were used to identify relevant articles. We focused on articles published within the last 5 years. Search terms were pre-eclampsia and complications, pregnancy-induced hypertension and complications, long-term complications of pre-eclampsia, and long-term follow-up of pre-eclampsia.ResultsTwo hundred and fifty-eight articles were identified; further analysis identified 91 that seemed relevant. After a thorough review, 19 articles were deemed relevant to identify complications women experience following pre-eclampsia.DiscussionCardiovascular disease is a major long-term risk. Early-onset pre-eclampsia contributes the greatest risk. Health promotion interventions that target women following a diagnosis of pre-eclampsia are needed. Inadequate knowledge exists to guide efforts to prevent long-term sequelae from pre-eclampsia. Women who experience pre-eclampsia have significant health risks following the diagnosis. Some risks are immediate (elevated blood pressure) and some risks can take longer to develop (heart disease, diabetes, kidney disease). Because of these risks, it is critical to develop treatment strategies to prevent these risks if possible. There are also risks to the fetus/newborn and these may be amendable to intervention as well.
