Abstract
ObjectiveTo compare nonpregnant blood pressure and circulating metabolic factors between formerly pre‐eclamptic women who did and did not deteriorate to eclampsia.DesignRetrospective observational cohort study.SettingTertiary referral centre.PopulationFormerly pre‐eclamptic women with (n = 88) and without (n = 698) superimposed eclampsia.MethodsWomen who experienced pre‐eclampsia with or without superimposed eclampsia during their pregnancy or puerperium were tested for possible underlying cardiovascular risk factors at least 6 months postpartum. We measured blood pressure and determined cardiovascular and metabolic risk markers in a fasting blood sample. Groups were compared using Mann–Whitney U test, Spearman's Rho test or Fisher's Exact test (odds ratios).Main outcome measuresDifferences in postpartum blood pressures and features of the metabolic syndrome between formerly pre‐eclamptic and formerly eclamptic women.ResultsFormerly pre‐eclamptic women who developed eclampsia differed from their counterparts without eclampsia by a lower blood pressure (P < 0.01) with blood pressure correlating inversely with the likelihood of having experienced eclampsia (P < 0.001). In addition, formerly eclamptic women had higher circulating C‐reactive protein levels than formerly pre‐eclamptic women (P < 0.05). All other circulating metabolic factors were comparable. Finally, 40% of all eclamptic cases occurred in the puerperium.ConclusionsFormerly pre‐eclamptic women with superimposed eclampsia have lower nonpregnant blood pressure compared with their counterparts without neurological sequelae with blood pressure negatively correlated to the occurrence of eclampsia. As about 40% of all eclamptic cases occur postpartum, routine blood pressure monitoring postpartum should be intensified.Tweetable abstractNonpregnant blood pressure of formerly pre‐eclamptic women is negatively correlated to the occurrence of eclampsia.
