Abstract
Abstract
Background
Prior evidence has suggested that pregnancy complications are associated with a higher risk of cardiovascular disease in women. However, associations between coexisting multiple pregnancy complications and incident cardiovascular disease remains unclear.
Purpose
To examine the risk of ischemic heart disease (IHD), stroke, atrial fibrillation or heart failure among women after their first pregnancy with a history of multiple pregnancy complications and women with a history of single-pregnancy complications, compared to women without pregnancy complications.
Methods
This retrospective cohort included women aged 16–45 years who had their first pregnancy between 2000 and 2018 in Wales using the Secure Anonymised Information Linkage (SAIL) Databank. Data were extracted from various sources such as Office for National Statistics (ONS) birth and death extracts, hospital admission, outpatient, emergency department and General Practice data sources, and pregnancy related data such as maternal indicators and national community child health. Cox proportional hazard regression was used to evaluate the association between multiple or specific single pregnancy complications and incidence of cardiovascular disease.
Results
A total of 298,515 women were included in the study, of which 64,794 (21.7%) women experienced a single pregnancy complication, and 10,038 (3.38%) women experienced more than one complication during their first pregnancy. During the a median of 9.7 years of follow-up, 2,484 women developed incident cardiovascular disease. IHD had the highest incidence rate among women with multiple pregnancy complications at 9.06 (7.36–11.15) per 10,000 person-years, compared to 4.24 (3.77–4.78) among women with a single pregnancy complication and 2.40 (2.20–2.61) among women without any pregnancy complications. After adjusting for potential confounding factors, compared to no previous pregnancy complications, a history of multiple pregnancy complications was associated with a higher risk of heart failure [hazard ratio (HR) 3.18 (95% confidence interval (CI) 2.34–4.32)], IHD [HR 2.88 (95% CI 2.27–3.67)], stroke [HR 2.03 (95% CI 1.55–2.65)] and atrial fibrillation [HR 1.80 (95% CI 1.20–2.72)]. There was also a consistent trend for a higher risk of all outcomes in women with a history of single-pregnancy complications compared to women without complications during the first pregnancy (Figure 1).
Conclusion
This population-scale study used anonymised individual-level linked data from multiple routinely collected data sources. In almost 300,000 women with a previous pregnancy, multiple pregnancy complications were associated with a higher risk of incident cardiovascular disease, including heart failure, ischaemic heart disease, stroke and atrial fibrillation. Women who experience multiple pregnancy complications may benefit from targeted intervention strategies to reduce their risk of incident cardiovascular disease.

Abstract
Abstract
Background
Previous studies have associated pregnancy complications with a higher risk of cardiovascular disease. However, previous studies have not sufficiently evaluated the impact of broad range of pregnancy complications or common cardiovascular conditions individually. Furthermore, most previous studies have relied on data from hospital admission records only, which may not have adequately accounted for conditions that may not result in an inpatient hospital admission, such as atrial fibrillation.
Purpose
To examine the risk of ischemic heart disease (IHD), stroke, atrial fibrillation or heart failure among women after their first pregnancy with a history of pregnancy complications compared to women without pregnancy complications in a large nationwide study using linked routinely collected data.
Methods
A retrospective cohort study was conducted using the Secure Anonymised Information Linkage (SAIL) Databank and included women aged 16–45 years who had their first pregnancy between 2000 and 2018 in Wales. Data were extracted from various sources such as Office for National Statistics (ONS) birth and death extracts, hospital admission, outpatient, emergency department and General Practice data sources, and pregnancy related data such as maternal indicators and national community child health. Survival analyses were conducted using Cox proportional hazard regression models adjusted for hypertension, diabetes, hyperlipidaemia, congenital and valvular heart diseases, multifetal pregnancy ethnicity, maternal age, calendar year of first birth and index of multiple deprivation.
Results
A total of 298,515 women were included in the study, of which 74,832 (25.1%) had a history of any pregnancy complication during their first pregnancy. During a median of 9.7 years follow-up time, 2,484 women developed at least one cardiovascular condition. Among women with a history of pregnancy complication in their first pregnancy, IHD had the highest incidence rate at 4.94 (95% confidence interval (CI) 4.44–5.49) per 10,000 person-years, and atrial fibrillation was the lowest at 1.92 (95% CI 1.62–2.28). The history of any pregnancy complication during the first pregnancy was associated with a higher risk of all cardiovascular conditions examined, including heart failure [hazard ratio (HR) 1.93 95% CI 1.61–2.31)], IHD [HR 1.82 (95% CI 1.58–2.10)], stroke [HR 1.39 (95% CI 1.20–1.61)] and atrial fibrillation [HR 1.33 (95% CI 1.08–1.65) (Figure 1).
Conclusion
This population-scale study used anonymised individual-level linked data from multiple routinely collected data sources. A history of pregnancy complications during first pregnancy was associated with a higher risk of incident cardiovascular conditions, including heart failure, ischaemic heart disease, stroke and atrial fibrillation. Applying primary preventive measures and risk assessments for cardiovascular disease after the first pregnancy may mitigate the higher risk among these women.

Background
Pregnancy-related complications have been previously associated with incident cardiovascular disease. However, data are scarce on the association between pregnancy-related complications and incident atrial fibrillation (AF). This systematic review examines associations between pregnancy-related complications and incident AF.
Methods
A systematic search of the literature utilising MEDLINE and EMBASE (Ovid) was conducted from 1990 to 6 April 2020. Observational studies examining the association between pregnancy-related complications including hypertensive disorders of pregnancy (HDP), gestational diabetes, placental abruption, preterm birth, low birth weight, small-for-gestational-age and stillbirth, and incidence of AF were included. Screening and data extraction were conducted independently by two reviewers. Inverse-variance random-effects models were used to pool hazard ratios.
Results: Six observational studies met the inclusion criteria
one case-control study and five retrospective cohort studies, with four studies eligible for meta-analysis. Sample sizes ranged from 1,839-1,303,365. Mean/median follow-up for the cohort studies ranged from 7-36 years. Most studies reported an increased risk of incident AF associated with pregnancy-related complications. The pooled summary statistic from four studies reflected a greater risk of incident AF for HDP (hazard ratio (HR) 1.47, 95% confidence intervals (CI) 1.18-1.84; I2 = 84%) and from three studies for pre-eclampsia (HR 1.71, 95% CI 1.41-2.06; I2 = 64%; Figure).
Conclusions
The results of this review suggest that pregnancy-related complications particularly pre-eclampsia appear to be associated with higher risk of incident AF. The small number of included studies and the significant heterogeneity in the pooled results suggest further large-scale prospective studies are required to confirm the association between pregnancy-related complications and AF.

Abstract
Abstract
Background
Anticoagulation is essential to prevent recurrent venous thromboembolism (VTE) during pregnancy in women with a history of preconception VTE. However, information on the safety of anticoagulant drugs in this setting is limited.
Purpose
To investigate the risk of maternal and foetal adverse outcomes associated with anticoagulant exposure during pregnancy.
Methods
Nationwide cohort of all pregnant women in Denmark with preconception VTE, 2000–2017. We linked individual-level data from nationwide registries on anticoagulant exposure, maternal and foetal outcomes.
Results
Among 5,099 pregnancies in 3,246 women with preconception VTE (mean age 31 years, 41% nulliparous), 36.4% were exposed to anticoagulants during first trimester (66.4% low-molecular-weight heparin (LMWH), 31.9% VKA, and 1.8% NOAC (Table). No maternal deaths occurred. Maternal outcomes were comparable among LMWH and unexposed women, whereas recurrent VTE and foetal loss was more prevalent in VKA and NOAC exposed women. Foetal risk was lowest in unexposed and LMWH exposed, whereas preterm birth was prevalent in VKA and NOAC exposed.
Table 1. Maternal and foetal outcomes in pregnant women with preconception VTE according to first trimester anticoagulant exposure Maternal outcomes No anticoagulants LMWH VKA NOAC Total pregnancies/singleton foetuses, N 3,244/2,722 1231/1,124 591/442 33 /26 Recurrent VTE, % (N) 2.7 (89) 3.3 (41) 6.4 (38) – (<5) Antenatal bleeding, % (N) 2.3 (73) 2.7 (33) 1.5 (9) 0 Preeclampsia, % (N) 3.0 (98) 2.1 (26) 4.4 (26) – (<5) Foetal loss, % (N) 13.4 (436) 6.6 (81) 22.2 (131) 21.2 (7) Foetal outcomes in live singleton births, except stillbirth Stillbirth, % (N) 0.6 (17) 0.6 (7) – (<5) 0 Mean gestational age, days/birthweight, gram 246/3,458 246/3,471 238/3,212 243/3,138 Preterm birth (<37 weeks), % (N) 41.1 (1,111) 38.3 (428) 63.2 (277) 57.7 (15) Very preterm birth (<28 weeks), % (N) 0.9 (24) 1.3 (14) 2.7 (12) 0 Small for gestational age, % (N) 4.2 (109) 4.5 (49) 4.8 (20) – (<5) Mean 5-minute Apgar score, (sd) 9.8 (0.8) 9.8 (0.7) 9.8 (1.0) 9.7 (1.0) Congenital defects 8.4 (226) 9.0 (100) 10.0 (44) – (<5) Counts are supressed in cells with <5 observations to prevent disclosure of potentially identifiable information.
Conclusion
Our findings are reassuring and in support of the recommendation of LMWH for pregnant women with prior VTE. Few women were exposed to NOAC during pregnancy, and the safety of NOACs cannot be substantiated with the current level of evidence.
