Impact of preventive screening and lifestyle interventions in women with a history of preeclampsia: A micro-simulation study

Health Economic Research Assessing the Value of Early Detection of Cardiovascular Disease: A Systematic Review

INTRODUCTION

Cardiovascular disease (CVD) is the most prominent cause of death worldwide and has a major impact on healthcare budgets. While early detection strategies may reduce the overall CVD burden through earlier treatment, it is unclear which strategies are (most) efficient.

AIM

This systematic review reports on the cost effectiveness of recent early detection strategies for CVD in adult populations at risk.

METHODS

PubMed and Scopus were searched to identify scientific articles published between January 2016 and May 2022. The first reviewer screened all articles, a second reviewer independently assessed a random 10% sample of the articles for validation. Discrepancies were solved through discussion, involving a third reviewer if necessary. All costs were converted to 2021 euros. Reporting quality of all studies was assessed using the CHEERS 2022 checklist.

RESULTS

In total, 49 out of 5552 articles were included for data extraction and assessment of reporting quality, reporting on 48 unique early detection strategies. Early detection of atrial fibrillation in asymptomatic patients was most frequently studied (n = 15) followed by abdominal aortic aneurysm (n = 8), hypertension (n = 7) and predicted 10-year CVD risk (n = 5). Overall, 43 strategies (87.8%) were reported as cost effective and 11 (22.5%) CVD-related strategies reported cost reductions. Reporting quality ranged between 25 and 86%.

CONCLUSIONS

Current evidence suggests that early CVD detection strategies are predominantly cost effective and may reduce CVD-related costs compared with no early detection. However, the lack of standardisation complicates the comparison of cost-effectiveness outcomes between studies. Real-world cost effectiveness of early CVD detection strategies will depend on the target country and local context.

Economic Evaluation of Prenatal and Postpartum Care in Women With Gestational Diabetes and Hypertensive Disorders of Pregnancy: A Systematic Review

OBJECTIVES

This study aimed to summarize evidence on the economic outcomes of prenatal and postpartum interventions for the management of gestational diabetes mellitus and hypertensive disorders of pregnancy (HDP), assess the quality of each study, and identify research gaps that may inform future research.

METHODS

Electronic databases including PubMed/MEDLINE, Embase, the Cochrane Library, and Cochrane Central Register of Controlled Trials were searched from January 1, 2000, to October 1, 2021. Selected studies were included in narrative synthesis and extracted data were presented in narrative and tabular forms. The quality of each study was assessed using the Consolidated Health Economic Evaluation Reporting Standards and Consensus on Health Economic Criteria list.

RESULTS

Among the 22 studies identified through the systematic review, 19 reported favorable cost-effectiveness of the intervention. For prenatal management of HDP, home blood pressure monitoring was found to be cost-effective compared with in-person visits in improving maternal and neonatal outcomes. For postpartum care, regular screening for hypertension or metabolic syndrome followed by subsequent treatment was found to be cost-effective compared with no screening in women with a history of gestational diabetes mellitus or HDP.

CONCLUSIONS

Existing economic evaluation studies showed that prenatal home blood pressure monitoring and postpartum screening for hypertension or metabolic syndrome were cost-effective. Nevertheless, limitations in the approach of the current economic evaluations may dampen the quality of the evidence and warrant further investigation.

Versorgungsrealität von Frauen nach hypertensiver Schwangerschaftserkrankung – eine monozentrische fragebogenbasierte Analyse

Einleitung Frauen nach einer hypertensiven Schwangerschaftserkrankung wird aufgrund ihres signifikant erhöhten kardiovaskulären Risikos zu Screeninguntersuchungen und primärer Prävention geraten. Diese Studie soll einen Beitrag zur Ermittlung der aktuellen Nachsorgepraxis leisten und aufzeigen, wie viele Frauen an den empfohlenen Nachsorgeuntersuchungen mit Beratung zur Reduktion von Risikofaktoren teilnehmen.

Material und Methoden Monozentrische Patientinnenbefragung von 113 Frauen, welche im Zeitraum von 2014 bis 2019 von einer hypertensiven Schwangerschaftserkrankung betroffen waren. Es erfolgte eine deskriptive statistische Auswertung.

Ergebnisse Eine Nachsorgeuntersuchung erfolgte bei 54% der Frauen. Es wurden 47% der Patientinnen im persönlichen Gespräch über ihre Erkrankung informiert und auf mögliche langfristige gesundheitliche Konsequenzen hingewiesen. Von 67 übergewichtigen Frauen (BMI≥25 kg/m2) erhielten 23% eine Empfehlung zur Steigerung der körperlichen Aktivität und 13% wurde zur Gewichtsreduktion geraten. Es stellten sich signifikant mehr Frauen mit höherer Krankheitslast (BMI, p=0,027; arterieller Hypertonus, p=0,016) und gravierender Ausprägung der Erkrankung (Eklampsie, Aufenthalt auf einer Intensivstation, jeweils p=0,049) zu weiteren Untersuchungen vor.

Schlussfolgerung Die vorliegenden Ergebnisse legen nahe, dass die Maßnahmen zur Prävention und Früherkennung von kardiovaskulären Erkrankungen in unserem Patientinnenkollektiv nicht ausgeschöpft wurden. Unabhängig des Ausprägungsgrades der Erkrankung sollten alle Frauen eine Empfehlung zur Teilnahme an Nachsorgeuntersuchung erhalten.

Differences in epidemiology of patients with preeclampsia between China and the US (Review)

Preeclampsia (PE) is a complex complication that occurs during pregnancy. Studies indicated that morbidity from PE exhibits marked variations among geographical areas. Disparities in the incidence of PE between China and the US may be due to differences in ethnicity and genetic susceptibility, maternal age, sexual culture, body mass index, diet, exercise, multiple pregnancies and educational background. These epidemiological differences may give rise to differences between the two countries in terms of diagnostic and therapeutic criteria for PE. PE may be largely attributed to susceptibility genes and lifestyles, such as diet, body mass index and cultural norms regarding sexual relationships. The epidemiologic differences of patients with PE between the two countries indicated that appropriate prevention plans for PE require to be developed according to local conditions.

Awareness of obstetricians for long-term risks in women with a history of preeclampsia or HELLP syndrome

Purpose

Hypertensive disorders of pregnancy are still a leading cause of maternal and neonatal morbidity and mortality worldwide. Women with a history of preeclampsia have an increased risk for future cardiovascular and cerebrovascular disease, renal disease as well as diabetes mellitus. There is little knowledge on postpartum risk management. The aim of this study was to assess follow-up care for patients after pre-eclampsia or HELLP syndrome.

Methods

This questionnaire-based cross-sectional study aimed to evaluate the current recommendations of obstetricians in Austria regarding follow-up care, long-term risk counselling and risk of recurrence in future pregnancies after preeclampsia or HELLP syndrome. Data were collected using a survey, based on recommendations given by three substantial guidelines on hypertensive disorders of pregnancy, which was distributed via e-mail to 69 public obstetric departments in Austria. Each obstetric department was required to answer one questionnaire per local protocol.

Results

Our results revealed that of the 48 participating hospitals most obstetricians are aware of the importance of follow-up care for women after a pregnancy complicated by preeclampsia. Our data show that most physicians counselled patients about the future cardiovascular health risks associated with preeclampsia or HELLP syndrome (79.2%). Most obstetricians recommended lifestyle modification (77.1%) and continued blood pressure measurements (97.9%). All centers stated to counsel about the risk of recurrence (100%). However, counselling regarding follow-up care to exclude kidney damage (37.5%) and underlying diseases like thrombophilia (39.6%) were less prioritized.

Conclusions

We were able to show that counselling concerning the risk of long-term cardiovascular disease and risk of recurrence after a pregnancy complicated by preeclampsia or HELLP syndrome has been established in obstetric departments in public hospitals. Regarding the evaluation of underlying chronic diseases such as thrombophilia or renal disease, as well as counselling on the future risk of renal disease is still improvable according to our data. Further evaluation of follow-up care after hypertensive disorders of pregnancy in the outpatient and private sector and implementation of structured guidelines for follow-up, as well as screening for cardiovascular disease are necessary to ensure adequate risk management and to provide opportunities for prevention.

Pre-eclampsia and long-term health outcomes for mother and infant: an umbrella review

BACKGROUND

Pre-eclampsia is a pregnancy-associated condition with complex disease mechanisms and a risk factor for various long-term health outcomes for the mother and infant.

OBJECTIVE

To summarise evidence on the association of pre-eclampsia with long-term health outcomes arising in women and/or infants.

SEARCH STRATEGY

PubMed, EMBASE, Scopus and ISI Web of Science were searched from inception to July 2020.

SELECTION CRITERIA

Systematic reviews and meta-analyses examining associations between pre-eclampsia and long-term health outcomes in women and their infants.

DATA COLLECTION AND ANALYSIS

Data were extracted by two independent reviewers. We re-estimated the summary effect size by random-effects and fixed-effects models, the 95% confidence interval, the 95% prediction interval, the between-study heterogeneity, any evidence of small-study effects and excess significance bias.

RESULTS

Twenty-one articles were included (90 associations). Seventy-nine associations had nominally statistically significant findings (P < 0.05). Sixty-five associations had large or very large heterogeneity. Evidence for small-study effects and excess significance bias was found in seven and two associations, respectively. Nine associations: cerebrovascular disease (cohort studies), cerebrovascular disease (overall), cardiac disease (cohort studies), dyslipidaemia (all studies), risk of death (late-onset pre-eclampsia), fatal and non-fatal ischaemic heart disease, cardiovascular mortality (cohort studies), any diabetes or use of diabetic medication (unadjusted), and attention deficit/hyperactivity disorder (ADHD) (adjusted) were supported with robust evidence.

CONCLUSION

Many of the meta-analyses in this research field have caveats casting doubts on their validity. Current evidence suggests an increased risk for women to develop cardiovascular-related diseases, diabetes and dyslipidaemia after pre-eclampsia, while offspring exposed to pre-eclampsia are at higher risk for ADHD.

TWEETABLE ABSTRACT

Cardiovascular and cerebrovascular diseases were supported with convincing evidence for long-term health outcomes after pre-eclampsia.

Disparities in Cardiovascular Care and Outcomes for Women From Racial/Ethnic Minority Backgrounds

Purpose of review

Racial, ethnic, and gender disparities in cardiovascular care are well-documented. This review aims to highlight the disparities and impact on a group particularly vulnerable to disparities, women from racial/ethnic minority backgrounds.

Recent findings

Women from racial/ethnic minority backgrounds remain underrepresented in major cardiovascular trials, limiting the generalizability of cardiovascular research to this population. Certain cardiovascular risk factors are more prevalent in women from racial/ethnic minority backgrounds, including traditional risk factors such as hypertension, obesity, and diabetes. Female-specific risk factors including gestational diabetes and preeclampsia as well as non-traditional psychosocial risk factors like depressive and anxiety disorders, increased child care, and familial and home care responsibility have been shown to increase risk for cardiovascular disease events in women more so than in men, and disproportionately affect women from racial/ethnic minority backgrounds. Despite this, minimal interventions to address differential risk have been proposed. Furthermore, disparities in treatment and outcomes that disadvantage minority women persist. The limited improvement in outcomes over time, especially among non-Hispanic Black women, is an area that requires further research and active interventions.

Summary

Understanding the lack of representation in cardiovascular trials, differential cardiovascular risk, and disparities in treatment and outcomes among women from racial/ethnic minority backgrounds highlights opportunities for improving cardiovascular care among this particularly vulnerable population.

Preeclampsia and long-term coronary artery disease: How to minimize the odds?

Preeclampsia (PE) is a hypertensive disorder of pregnancy that can cause detrimental obstetric outcomes if not managed properly. Current evidence demonstrates higher risk for long-term cardiovascular disease in preeclamptic women. Even in uncomplicated pregnancies, the heart work overload often reveals subtle cardiac defects or abnormalities, which otherwise remain undiagnosed in women without a history of pregnancy. Pathophysiologic patterns occurring in PE patients resemble biochemical responses observed in cases of cardiovascular disease. It has been estimated that women with an obstetric history of PE are more likely to develop coronary artery disease in the long run. Currently, additionally to whether any approach could actually contribute to minimizing mortality and morbidity among these affected populations, there is no consensus regarding management for these patients. In this review we summarized the current scientific evidence regarding the correlation between PE and long-term coronary artery disease. Based on this knowledge, we propose postpartum and lifetime management for these high-risk patients in order to minimize morbidity and mortality within this population.
