Atherosclerosis after pre-eclampsia: systematic review and meta-analysis

Abstract

Objective Pre-eclampsia complicates up to 8% of pregnancies and is associated with increased risk of ischemic cardiac and cerebral disease, which may be prevented through management of cardiovascular risk when early disease stages are detected. This meta-analysis aimed to determine the prevalence of clinical and subclinical atherosclerosis in women after pre-eclamptic vs non-pre-eclamptic pregnancy with advancing maternal age.Methods A systematic search of the literature was conducted in PubMed, Embase and Web of Science for studies reporting on the prevalence of atherosclerosis in women with a previous pre-eclamptic pregnancy and those with a previous uncomplicated pregnancy. Any systemic atherosclerosis documented using ultrasound or computed tomography was included. Random-effects meta-analysis was used to compute the odds ratio (OR) with 95% CI for the association between pre-eclampsia and the presence of atherosclerosis. Subgroup analysis was conducted according to average maternal age at evaluation.Results A total of 11 articles were included (13 217 participants). The average maternal age at evaluation ranged from 32 to 60 years. Within this age range, the pooled OR for the presence of atherosclerotic plaque after pre-eclampsia was 1.57 (95% CI, 1.39-1.78). The pooled OR of developing atherosclerotic plaque after a pre-eclamptic vs non-pre-eclamptic pregnancy increased gradually with advancing maternal age. The OR was not significant in the 30-39-year-old group (0.64 (95% CI, 0.10-4.15)), but the odds of finding an atherosclerotic plaque were significantly increased after pre-eclamptic pregnancy in the 40-49-year-old group (OR, 1.59 (95% CI, 1.34-1.89)) and 50-60-year-old group (OR, 2.00 (95% CI, 1.30-3.08)). At any given age, the percentage plaque prevalence in formerly pre-eclamptic women was roughly equal to that seen 10 years later in women with a previous non-pre-eclamptic pregnancy.Conclusions Women with a previous pre-eclamptic pregnancy exhibit atherosclerosis more frequently and approximately 10 years earlier compared with women with a previous non-pre-eclamptic pregnancy. Targeted primary prevention is required to reduce morbidity and mortality from premature cardiovascular disease in women after pre-eclampsia. (c) 2025 The Author(s).
