Observational studies have shown an increased lifetime risk of cardiovascular disease (CVD) in women who experienced a hypertensive disorder in pregnancy. This risk is related to the severity of the pregnancy-related hypertensive disease and gestational age at onset. However, it has not been investigated whether these differences in CVD risk factors are already present at postpartum cardiovascular screening. We evaluated postpartum differences in CVD risk factors in 3 subgroups of patients with a history of hypertensive pregnancy. We compared the prevalence of common CVD risk factors postpartum among 448 women with previous early-onset preeclampsia, 76 women with previous late-onset preeclampsia, and 224 women with previous pregnancy-induced hypertension. Women with previous early-onset preeclampsia were compared with women with late-onset preeclampsia and pregnancy-induced hypertension and had significantly higher fasting blood glucose (5.29 versus 4.80 and 4.83 mmol/L), insulin (9.12 versus 6.31 and 6.7 uIU/L), triglycerides (1.32 versus 1.02 and 0.97 mmol/L), and total cholesterol (5.14 versus 4.73 and 4.73 mmol/L). Almost half of the early-onset preeclampsia women had developed hypertension, as opposed to 39% and 25% of women in the pregnancy-induced hypertension and late-onset preeclampsia groups, respectively. Our data show differences in the prevalence of common modifiable CVD risk factors postpartum and suggest that prevention strategies should be stratified according to severity and gestational age of onset for the hypertensive disorders of pregnancy.

INTRODUCTION:Cardiovascular disease (CVD) is the leading cause of mortality and morbidity in women. Epidemiological studies have shown an increased risk of a CVD event in women who have had a hypertensive disorder in one of their previous pregnancies. These data also suggest that these increased risks are associated with severity and time of onset of pre-eclampsia. Risk factors for CVD have not yet been compared between women who experienced early versus late and mild versus severe hypertensive disorders of pregnancy. OBJECTIVES:In this study we compared classic CVD risk factors of postpartum women with previous early-onset preeclampsia (EOPE), late onset pre-eclampsia (LOPE) and pregnancy induced hypertension (PIH). METHODS:A total of 81 women with previous EOPE (delivery required ⩽34weeks), 76 with LOPE (delivery ⩾36weeks) and 229 with PIH were included along with 79 healthy controls. Statistical analyses were performed using generalized linear models in PASW statistics 17.0, SPSS Inc. RESULTS:Adjusted means of blood pressure, fasting plasma glucose levels and LDL levels were significantly increased after all hypertensive disorders of pregnancy compared to controls. This increase of CVD risk factors was significantly correlated with severity and time of onset of the disease (Table 1). The prevalence of metabolic syndrome (BMI>30kg/m(2) and ⩾2 of the following; triglycerides ⩾150mg/dl, HDL cholesterol ⩾50mg/dl, systolic blood pressure ⩾130 or diastolic blood pressure ⩾85 and fasting plasma glucose levels ⩾100mg/dl) did not differ between the study groups; women who had PIH had the highest number of components of the metabolic syndrome (). CONCLUSION:These results further establish the predisposition to CVD in women with previous pre-eclampsia or PIH. EOPE is associated with a more pronounced CVD risk factor profile than LOPE or PIH, which may explain the previously described higher CVD event risk.
