INTRODUCTION: Women with a history of preeclampsia have increased risk of cardiovascular disease later in life. However, it is unclear if early gestational age at preeclampsia onset is associated with higher cardiovascular disease risk. This study aimed to test the association between gestational age at preeclampsia onset (including the early-onset/late-onset preeclampsia distinction) and subclinical atherosclerosis and arterial stiffness in age-matched women 12 years after index pregnancy MATERIAL AND METHODS: Eligible participants were identified in two Danish registries. Main outcome measures were carotid plaque presence, carotid intima-media thickness, aortic pulse wave velocity, and augmentation index adjusted for heart rate RESULTS: Twenty-four women with previous early-onset preeclampsia, 24 with previous late-onset preeclampsia and 24 with previous normotensive pregnancies were included after matching on age (+/- 2 years) and time since delivery (+/- 1 year). In all outcome measures, the early-onset group had the highest percentage or mean value. In the adjusted analysis, the early-onset group significantly differed from the late-onset group in all outcome measures except aortic pulse wave velocity. The early-onset group also had significantly higher carotid intima-media thickness (average and left) compared to the normotensive group. Noteworthy, gestational age at preeclampsia onset as a continuous variable was significantly associated to both carotid plaque presence and carotid intima-media thickness (average and right) CONCLUSIONS: Gestational age at preeclampsia onset is negatively associated with markers of subclinical atherosclerosis 12 years after delivery. Potentially, gestational age at preeclampsia onset might be helpful in directing cardiovascular disease prevention after preeclampsia. This article is protected by copyright. All rights reserved.
