Objective: Hypertensive disorders during pregnancy increase cardiovascular risk later in life by 2 to 9 -fold. Endothelial activation is one of the underlying mechanisms of cardiovascular risk. Therefore, we decided to investigate endothelial activation in primiparous women, 2.5 years after a hypertensive pregnancy disorder. Study design: Plasma samples were taken from women 2.5 years after gestational hypertension (GH) or late onset preeclampsia (cases) and from women 2.5 years after a normotensive pregnancy (controls). We studied the effects of patient plasma on the endothelial barrier function of primary human umbilical vein endothelial cells (HUVECs) using Electric Cell-Substrate Impedance Sensing (ECIS) and we measured levels of endothelial activation markers soluble intercellular adhesion molecule 1 (sICAM-1) and soluble endothelial selectin (sE-selectin) in the plasma samples of patients. Results: Plasma from primiparous women with a history of late onset preeclampsia disrupted the endothelial barrier more than plasma from women with a history of GH. Endothelial resistance was reduced by 22% in samples taken after preeclampsia, 16% after normotensive pregnancy and 3% after GH (p <= 0.0001 GH versus preeclampsia and p = 0.0003 versus normotensive pregnancy). We did not find differences in the levels of soluble endothelial activation markers (sICAM-1 p = 0.326 and sE-selectin p = 0.978). However, the BMI >= 25 showed a strong correlation with increased levels of sICAM-1 (p = 0.046) and sE-selectin (p = 0.002). Conclusion: Our results indicate that GH and late onset preeclampsia are distinct disease entities with a different pathogenic mechanism underlying their cardiovascular risk. Furthermore, this study supports the hypothesis that these two diseases are early manifestations of cardiovascular vulnerability due to an unfavorable risk profile, and that obesity plays a main role. Our results suggest that this high-risk female population would be eligible for preventive care. (C) 2018 Elsevier B.V. All rights reserved.
