Expectant Management of Hypertensive Disorders of Pregnancy and Future Cardiovascular Morbidity.

ABSTRACT:

Objective

To test the hypothesis that a longer length of time between diagnosis of hypertensive disorders of pregnancy and delivery is associated with increased risk of cardiovascular morbidity in the years after delivery.

Methods

This is a retrospective cohort study based in the New York State Inpatient Database. The first delivery for all patients from 2005 to 2014 who delivered preterm with an International Classification of Diseases, 9th Revision, Clinical Modification code for hypertensive disorders of pregnancy (excluding isolated chronic hypertension) was included. The duration between diagnosis and delivery was divided into 7 days or less or more than 7 days. The primary outcome was admission for a composite of cardiovascular disease, stroke, or death after the index delivery through December 31, 2014.

Results

There were 22,594 patients with a median follow-up period of 5.2 years: 19,750 (87.4%) were delivered within 7 days of diagnosis and 2,844 (12.6%) were delivered more than 7 days from diagnosis. The primary outcome occurred in 216 (1.1%) patients in the 0-7 days group (21 events/10,000 person-years) and 67 (2.4%) patients in the more than 7 days group (46 events/10,000 person-years), adjusted hazard ratio 1.45 (95% CI 1.09 to 1.93). The findings were robust in a number of sensitivity analyses.

Conclusions

Prolonged expectant management of preterm hypertensive disorders of pregnancy is associated with an increased risk of maternal cardiac disease in the ensuing years.

Project description:OBJECTIVES:Hypertensive disorders of pregnancy (HDP) affect one in ten pregnancies and often persist postpartum when complications can occur. We aimed to determine the effectiveness and safety of pharmacological interventions, other interventions and different care models for postpartum hypertension management. DESIGN:A systematic review was undertaken. Nine electronic databases, including Medline, were searched from inception to 16 March 2017. After duplicate removal, 4561 records were screened. Two authors independently selected studies, extracted study characteristics and data, and assessed methodological quality. SETTING:Randomised controlled trials, case-control studies and cohort studies from any country and healthcare setting. PARTICIPANTS:Postnatal women with HDP. INTERVENTIONS:Therapeutic intervention for management of hypertension, compared with another intervention, placebo or no intervention. PRIMARY AND SECONDARY OUTCOME MEASURES:Outcome data were collected for maternal mortality and severe morbidity; systolic, diastolic and mean arterial blood pressure (BP) control; and safety data. Secondary outcome data collected included the length of postnatal hospital stay and laboratory values. RESULTS:39 studies were included (n=2901). Results were heterogeneous in terms of intervention, comparison and outcome requiring a narrative approach. There were insufficient data to recommend any single pharmacological intervention. 18 studies reported calcium-channel blockers, vasodilators and beta-blockers lowered BP postpartum. 12 of these reported safety data. Limited data existed regarding management in the weeks following hospital discharge. Neither loop diuretics (three studies) nor corticosteroids (one study) produced clinical benefit. Uterine curettage significantly reduced BP over the first 48?hours postpartum (range 6-13?mm Hg) compared with standard care (eight studies), with safety data only reported by four of eight studies. CONCLUSION:There was insufficient evidence to recommend a particular BP threshold, agent or model of care, but three classes of antihypertensive appeared variably effective. Further comparative research, including robust safety data, is required. Curettage reduced BP, but without adequate reporting of harms, so it cannot currently be recommended.

Project description:BackgroundAdvances in research suggest the possibility of improving routine clinical care for preeclampsia using screening (predictive) and diagnostic tests. The views of women should be incorporated into the way in which such tests are used. Therefore, we explored the views of women with experience of preeclampsia and other hypertensive disorders in pregnancy (HDPs) about predictive and diagnostic tests, treatment risks, and expectant management.MethodEight hundred and seven women with experience of preeclampsia or other HDPs completed an online questionnaire. These women were participants in the Preeclampsia Registry (USA). The questionnaire contained 22 items to elicit women's views about predictive tests (n = 8); diagnostic tests (n = 5); treatment risks (n = 7), and expectant management (n = 2). An optional text box allowed participants to add qualitative open-ended comments. Levels of agreement with the statements were reported descriptively for the sample as a whole, and a preliminary investigation of the role of lived experience in shaping women's views was conducted by comparing subgroups within the sample based on time of HDP delivery (preterm/term). The qualitative data provided in the optional text box was analysed using inductive thematic analysis to examine participants' responses.ResultsWomen generally favored predictive and diagnostic testing, although not because they would opt for termination of pregnancy. Participants generally disagreed that taking daily low-dose aspirin (LDA) would make them nervous, with disagreement significantly higher in the preterm delivery subgroup. A high proportion of participants, especially in the preterm delivery subgroup, would take LDA throughout pregnancy. The majority of participants would be more worried about the possibility of preeclampsia than about the risks of treatments to their health (60%), and that proportion was significantly higher in the preterm delivery subgroup. There were no differences between subgroups in the views expressed about expectant management, although opinion was divided in both groups. Overall, most participants opted to put the baby's interests first.ConclusionWomen with experience of hypertensive disorders were enthusiastic about improved predictive and diagnostic tests. However, varied views about treatment options and expectant management suggest the need for a shared decision-making tool to enable healthcare professionals to support pregnant women's decision-making to maximize the utility of these tests and interventions.

Project description:BackgroundWomen with a history of hypertensive disorders of pregnancy (HDP) are nearly twice as likely to develop cardiovascular disease (CVD) as those who are normotensive during pregnancy. However, the emergence of CVD risk factors after HDP is less well-understood.ObjectiveTo identify associations between HDP and maternal CVD risk factors and chart the trajectory of risk factor development after pregnancy.DesignObservational cohort study.SettingUnited States.Participants58 671 parous NHS II (Nurses' Health Study II) participants who did not have CVD or risk factors of interest at baseline.MeasurementsWomen were followed for self-reported physician diagnosis of chronic hypertension and hypercholesterolemia and confirmed type 2 diabetes mellitus (T2DM) from their first birth through 2013; mean follow-up ranged from 25 to 32 years across these end points. Multivariable Cox proportional hazards models estimated hazard ratios (HRs) and 95% CIs, with adjustment for prepregnancy confounders.ResultsCompared with women who were normotensive during pregnancy, those with gestational hypertension (2.9%) or preeclampsia (6.3%) in their first pregnancy had increased rates of chronic hypertension (HRs, 2.8 [95% CI, 2.6 to 3.0] and 2.2 [CI, 2.1 to 2.3], respectively), T2DM (HRs, 1.7 [CI, 1.4 to 1.9] and 1.8 [CI, 1.6 to 1.9], respectively), and hypercholesterolemia (HRs, 1.4 [CI, 1.3 to 1.5] and 1.3 [CI, 1.3 to 1.4], respectively). Although these women were more likely to develop CVD risk factors throughout follow-up, the relative risk for chronic hypertension was strongest within 5 years after their first birth. Recurrence of HDP further elevated risks for all end points.LimitationParticipants self-reported HDP.ConclusionWomen with HDP in their first pregnancy had increased rates of chronic hypertension, T2DM, and hypercholesterolemia that persisted for several decades. These women may benefit from lifestyle intervention and early screening to reduce lifetime risk for CVD.Primary funding sourceNational Institutes of Health.
