10-Year cardiovascular event risks for women who experienced hypertensive disorders in late pregnancy: the HyRAS study

ABSTRACT: BACKGROUND: Cardiovascular disease is the cause of death in 32% of women in the Netherlands. Prediction of an individual's risk for cardiovascular disease is difficult, in particular in younger women due to low sensitive and specific tests for these women. 10% to 15% of all pregnancies are complicated by hypertensive disorders, the vast majority of which develop only after 36 weeks of gestation. Preeclampsia and cardiovascular disease in later life show both features of "the metabolic syndrome" and atherosclerosis. Hypertensive disorders in pregnancy and cardiovascular disease may develop by common pathophysiologic pathways initiated by similar vascular risk factors. Vascular damage occurring during preeclampsia or gestational hypertension may contribute to the development of future cardiovascular disease, or is already present before pregnancy. At present clinicians do not systematically aim at the possible cardiovascular consequences in later life after a hypertensive pregnancy disorder at term. However, screening for risk factors after preeclampsia or gestational hypertension at term may give insight into an individual's cardiovascular risk profile. METHODS: Women with a history of preeclampsia or gestational hypertension will be invited to participate in a cohort study 2,5 years after delivery. Participants will be screened for established modifiable cardiovascular risk indicators. The primary outcome is the 10-year cardiovascular event risk. Secondary outcomes include differences in cardiovascular parameters, SNP's in glucose metabolism, and neonatal outcome. DISCUSSION: This study will provide evidence on the potential health gains of a modifiable cardiovascular risk factor screening program for women whose pregnancy was complicated by hypertension or preeclampsia. The calculation of individual 10-year cardiovascular event risks will allow identification of those women who will benefit from primary prevention by tailored interventions, at a relatively young age.

Cost-effectiveness analysis of cardiovascular risk factor screening in women who experienced hypertensive pregnancy disorders at term

Objectives: To assess the cost-effectiveness of post-partum screening on cardiovascular risk factors and subsequent treatment in women with a history of gestational hypertension or pre-eclampsia at term. Study design: Two separate Markov models evaluated the cost-effectiveness analysis of hypertension (HT) screening and screening on metabolic syndrome (MetS), respectively, as compared to current practice in women with a history of term hypertensive pregnancy disorders. Analyses were performed from the Dutch health care perspective, using a lifetime horizon. One-way sensitivity analyses and Monte Carlo simulation evaluated the robustness of the results. Results: Both screening on HT and MetS in women with a history of gestational hypertension or pre-eclampsia resulted in increase in life expectancy (HT screening 0.23 year (95% CI -0.06 to 0.54); MetS screening 0.14 years (95% CI -0.16 to 0.45)). The gain in QALYs was limited, with HT screening and MetS screening generating 0.04 QALYs (95% CI -0.12 to 0.20) and 0.03 QALYs (95% CI -0.14 to 0.19), resulting in costs to gain one QALY of is an element of 4228 and is an element of 28,148, respectively. Analyses for uncertainty showed a chance of 74% and 75%, respectively, that post-partum screening is cost-effective at a threshold of is an element of 60,000/QALY. Conclusions: According to the available knowledge post-partum screening on cardiovascular risk factors and subsequent treatment in women with a history of gestational hypertension or pre-eclampsia at term is likely to be cost-effective.

Cardiovascular risk factors in women who had hypertensive disorders late in pregnancy:a cohort study

<p>OBJECTIVE: The purpose of this study was to determine cardiovascular risk factors in women with a history of hypertensive pregnancy disorders at term (HTP) 2.5 years after pregnancy.</p><p>STUDY DESIGN: In a multicenter cohort study in The Netherlands from June 2008 through November 2010, cardiovascular risk factors were compared between women with a history of HTP (HTP cohort, n = 306) and women with a history of normotensive pregnancies at term (NTP cohort, n = 99). HTP women had participated in a randomized, longitudinal trial assessing the effectiveness of induction of labor in women with hypertensive pregnancy disorders at term. All women were assessed 2.5 years after pregnancy for blood pressure, anthropometrics, glucose, glycosylated hemoglobin, insulin, homeostatic model assessment score, total cholesterol, high-density lipoprotein cholesterol, triglycerides, high-sensitivity C-reactive protein, and microalbumin and metabolic syndrome.</p><p>RESULTS: After a mean follow-up period of 2.5 years, hypertension (HTP, 34%; NTP, 1%; P <.001) and metabolic syndrome (HTP, 25%; NTP, 5%; P <.001) were more prevalent in HTP women compared with NTP women. HTP women had significantly higher systolic and diastolic blood pressure, higher body mass index, and higher waist circumference. Glucose, glycosylated hemoglobin, insulin, homeostatic model assessment score, total cholesterol, triglycerides, and high-sensitivity C-reactive protein levels were significantly higher and high-density lipoprotein cholesterol was significantly lower in HTP women.</p><p>CONCLUSION: In women with a history of HTP, hypertension and metabolic syndrome are more common, and they have higher levels of biochemical cardiovascular risk factors 2.5 years after pregnancy.</p>
