Maternal cardiovascular risk profile after placental abruption

Abstract

The prevalence of premature cardiovascular diseases (CVD) is increased in women with a history of maternal placental syndromes, including pregnancy-associated hypertensive disorders (eg, preeclampsia), fetal growth restriction, and placental abruption. Whereas previous studies have shown a high prevalence of CVD risk factors after pregnancies complicated by preeclampsia, this has not been studied for women with a history of placental abruption. To explore the association of placental abruption with CVD risk factors after delivery, we compared 75 women with a history of placental abruption with a control group of 79 women with uneventful pregnancies at 6 to 9 months postpartum for the presence of common CVD risk factors. In a subanalysis, data were stratified according to the presence or absence of concomitant hypertensive disease and further adjusted for potential confounders. Women with previous placental abruption had significantly higher mean systolic blood pressure, body-mass index, fasting blood glucose, C-reactive protein, total cholesterol, high-density lipoprotein-cholesterol, and low-density lipoprotein-cholesterol as compared with controls with only uneventful pregnancies. In the subanalysis, all differences remained significant for women with a history of placental abruption only (ie, without concomitant gestational hypertension), except for the associations with low-density lipoprotein-cholesterol and diastolic and systolic blood pressure. Most likely, the identified CVD risk factors predispose to placental abruption and development of premature CVD later in life. © 2013 American Heart Association, Inc.
