    Abstract:
    OBJECTIVE: Preeclampsia is associated with cardiovascular atherosclerotic events later in life. However, little is known about earlier subclinical signs of atherosclerosis. We aimed to investigate whether women who recently had preeclampsia show increased intima-media thickness (IMT), as marker of early atherosclerosis, compared with women with normal pregnancies or nulliparous women. METHODS: Intima-media thickness of carotid and femoral arteries measured by ultrasonography, and possible confounding risk factors as body mass index, blood pressure, serum lipids, smoking status, and family history of cardiovascular disease were compared among 22 nulliparous women, 22 primiparous women with normal pregnancy, and 22 primiparous women with early-onset preeclampsia at least 3 months postpartum and 6 weeks after ending lactation RESULTS: Except for slightly higher values for blood pressure, triglycerides, and homocysteine in the formerly preeclamptic women, no other clinical or biochemical differences were observed. The preeclampsia group showed an increased IMT (mean +/- standard deviation, 0.63 +/- 0.14 mm) of the common femoral artery compared with the normal pregnancy group (0.55 +/- 0.06 mm, P = .005) and to the nulliparous group (0.52 +/- 0.06 mm, P < .001). These differences remained significant after correction for possible confounders by multiple linear regression analyses. An increase in IMT of the common carotid artery between the normal pregnancy and the nulliparous group was observed, which became significant after adjustment for confounders. CONCLUSION: Preeclampsia and, to a lesser degree, normal pregnancy are associated with increased IMT. The association between increased IMT and (preeclamptic) pregnancy leads to the question of which comes first, which should be addressed in follow-up studies. LEVEL OF EVIDENCE: II-2.
