Abstract
BackgroundYounger women with previous preeclampsia have an increased risk of coronary atherosclerosis. It is unknown if this risk is associated with the time of onset of preeclampsia. ObjectivesThe aim of the study was to investigate if women with early-onset preeclampsia have a higher risk of coronary atherosclerosis compared to women with late-onset preeclampsia, independent of other perinatal risk factors. Study DesignA total of 911 women with previous preeclampsia aged 35-55 years participated in a clinical follow-up study, including clinical examination, comprehensive questionnaires, and cardiac computed tomography scan 13 years (range 0-28) after index pregnancy. Early-onset preeclampsia versus late-onset preeclampsia was defined as gestational age at delivery < versus ≥ 34+0 gestational weeks, respectively. The primary outcome of the study was the presence of coronary atherosclerosis on the cardiac computed tomography. A logistic regression analysis was performed to investigate the association between time of onset of preeclampsia, perinatal risk factors and the primary outcome. ResultsWomen with early-onset preeclampsia (N=139) were older (46.2±5.7 vs. 44.4±5.5 years, P<0.001), more likely to have hypertension (51.1% vs. 35.1%, P=<0.001), and had a higher body mass index (27.9±6.3 vs. 26.9±5.5 kg/m2, P=0.051) compared to women with late-onset preeclampsia (N=772) at follow-up. The prevalence of the primary outcome coronary atherosclerosis on the cardiac computed tomography was 28.8% vs. 22.2% (P=0.088) with an adjusted OR=1.74, 95% CI (1.01-3.01), P=0.045 after adjustment for maternal age at index pregnancy, pre-pregnancy body mass index, parity, diabetes in pregnancy, smoking in pregnancy, offspring birth weight and sex, and follow-up length. ConclusionsWomen with early-onset preeclampsia had a slightly higher risk of coronary atherosclerosis compared to women with late-onset preeclampsia. However, based on the current evidence it does not seem indicated to limit screening, diagnostic and preventive measures for cardiovascular disease only to women with early-onset preeclampsia.
