Lin X, Yong J, Gan M, Tang S, Du J. Impact of low-dose aspirin exposure on obstetrical outcomes: a meta-analysis. J Psychosom Obstet Gynaecol 2024; 45:2344079. [PMID: 38712869 DOI: 10.1080/0167482x.2024.2344079] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2024] [Accepted: 04/12/2024] [Indexed: 05/08/2024] Open
Abstract
OBJECTIVE To assess the impact of low-dose aspirin (LDA) on obstetrical outcomes through a meta-analysis of placebo-controlled randomized controlled trials (RCTs). METHODS A systematic search of the PubMed, Cochrane Library, Web of Science and Embase databases from inception to January 2024 was conducted to identify studies exploring the role of aspirin on pregnancy, reporting obstetrical-related outcomes, including preterm birth (PTB, gestational age <37 weeks), small for gestational age (SGA), low birth weight (LBW, birthweight < 2500g), perinatal death (PND), admission to the neonatal intensive care unit (NICU), 5-min Apgar score < 7 and placental abruption. Relative risks (RRs) were estimated for the combined outcomes. Subgroup analyses were performed by risk for preeclampsia (PE), LDA dosage (<100 mg vs. ≥100 mg) and timing of onset (≤20 weeks vs. >20 weeks). RESULTS Forty-seven studies involving 59,124 participants were included. Compared with placebo, LDA had a more significant effect on low-risk events such as SGA, PTB and LBW. Specifically, LDA significantly reduced the risk of SGA (RR = 0.91, 95% CI: 0.87-0.95), PTB (RR = 0.93, 95% CI: 0.89-0.97) and LBW (RR = 0.94, 95% CI: 0.89-0.99). For high-risk events, LDA significantly lowered the risk of NICU admission (RR = 0.93, 95% CI: 0.87-0.99). On the other hand, LDA can significantly increase the risk of placental abruption (RR = 1.72, 95% CI: 1.23-2.43). Subgroup analyses showed that LDA significantly reduced the risk of SGA (RR = 0.86, 95% CI: 0.77-0.97), PTB (RR = 0.93, 95% CI: 0.88-0.98) and PND (RR = 0.65, 95% CI: 0.48-0.88) in pregnant women at high risk of PE, whereas in healthy pregnant women LDA did not significantly improve obstetrical outcomes, but instead significantly increased the risk of placental abruption (RR = 5.56, 95% CI: 1.92-16.11). In pregnant women at high risk of PE, LDA administered at doses ≥100 mg significantly reduced the risk of SGA (RR = 0.77, 95% CI: 0.66-0.91) and PTB (RR = 0.56, 95% CI: 0.32-0.97), but did not have a statistically significant effect on reducing the risk of NICU, PND and LBW. LDA started at ≤20 weeks significantly reduced the risk of SGA (RR = 0.76, 95% CI: 0.65-0.89) and PTB (RR = 0.56, 95% CI: 0.32-0.97). CONCLUSIONS To sum up, LDA significantly improved neonatal outcomes in pregnant women at high risk of PE without elevating the risk of placental abruption. These findings support LDA's clinical application in pregnant women, although further research is needed to refine dosage and timing recommendations.

[PMID: 39147366 PMCID: PMC11441416 DOI: 10.1097/aog.0000000000005674] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2024] [Accepted: 05/30/2024] [Indexed: 07/18/2024]
Abstract
OBJECTIVE To examine the association between elevated blood pressure (BP) in the early third trimester and cardiometabolic health 10-14 years after delivery. METHODS This is a secondary analysis from the prospective HAPO FUS (Hyperglycemia and Adverse Pregnancy Outcome Follow-Up Study). Blood pressure in the early third trimester was categorized per American College of Cardiology/American Heart Association thresholds for: normal BP below 120/80 mm Hg (reference), elevated BP 120-129/below 80 mm Hg, stage 1 hypertension 130-139/80-89 mm Hg, and stage 2 hypertension 140/90 mm Hg or higher. Cardiometabolic outcomes assessed 10-14 years after the index pregnancy were type 2 diabetes mellitus and measures of dyslipidemia, including low-density lipoprotein (LDL) cholesterol 130 mg/dL or higher, total cholesterol 200 mg/dL or higher, high-density lipoprotein (HDL) cholesterol 40 mg/dL or lower, and triglycerides 200 mg/dL or higher. Adjusted analysis was performed with the following covariates: study field center, follow-up duration, age, body mass index (BMI), height, family history of hypertension and diabetes, smoking and alcohol use, parity, and oral glucose tolerance test glucose z score. RESULTS Among 4,692 pregnant individuals at a median gestational age of 27.9 weeks (interquartile range 26.6-28.9 weeks), 8.5% (n=399) had elevated BP, 14.9% (n=701) had stage 1 hypertension, and 6.4% (n=302) had stage 2 hypertension. At a median follow-up of 11.6 years, among individuals with elevated BP, there was a higher frequency of diabetes (elevated BP: adjusted relative risk [aRR] 1.88, 95% CI, 1.06-3.35; stage 1 hypertension: aRR 2.58, 95% CI, 1.62-4.10; stage 2 hypertension: aRR 2.83, 95% CI, 1.65-4.95) compared with those with normal BP. Among individuals with elevated BP, there was a higher frequency of elevated LDL cholesterol (elevated BP: aRR 1.27, 95% CI, 1.03-1.57; stage 1 hypertension: aRR 1.22, 95% CI, 1.02-1.45, and stage 2 hypertension: aRR 1.38, 95% CI, 1.10-1.74), elevated total cholesterol (elevated BP: aRR 1.27, 95% CI, 1.07-1.52; stage 1 hypertension: aRR 1.16, 95% CI, 1.00-1.35; stage 2 hypertension: aRR 1.41 95% CI, 1.16-1.71), and elevated triglycerides (elevated BP: aRR 2.24, 95% CI, 1.42-3.53; stage 1 hypertension: aRR 2.15, 95% CI, 1.46-3.17; stage 2 hypertension: aRR 3.24, 95% CI, 2.05-5.11) but not of low HDL cholesterol. CONCLUSION The frequency of adverse cardiometabolic outcomes at 10-14 years after delivery was progressively higher among pregnant individuals with BP greater than 120/80 in the early third trimester.

[PMID: 39174670 DOI: 10.1038/s41371-024-00944-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Revised: 07/12/2024] [Accepted: 08/06/2024] [Indexed: 08/24/2024]
Abstract
Chronic hypertension (CH) during pregnancy, identified before or within the first 20 weeks, presents varying risks depending on the timing of diagnosis. This real-world study was conducted from January 2018 to June 2023 and included singleton pregnancies with CH to compare pre-pregnancy CH (Group 1) and newly diagnosed CH (Group 2). There were 565 women in the final analysis, with 307 in Group 1 with pre-pregnancy CH and 258 in Group 2 with new-onset CH. Those in Group 1 more frequently had pre-gestational diabetes and a history of hypertensive disorders in pregnancy, whereas Group 2 had a higher incidence of excessive gestational weight gain. Notably, 56.2% of Group 2 patients did not receive antihypertensive treatment before 20 weeks, while the proportion was 36.2% in Group 1, resulting in a significant difference in baseline blood pressure. The study revealed higher incidences of preterm preeclampsia (44.2% vs. 34.9%) and placental abruption (5.4% vs. 2.0%) in Group 2 compared to Group 1. After adjustment, logistic regression indicated that Group 2 had a 1.8-fold higher risk of preterm preeclampsia than Group 1. These findings suggest that pregnant women newly diagnosed with CH in the first 20 weeks face increased adverse outcomes compared to those diagnosed before pregnancy. Intense monitoring and earlier intervention may help manage women with new-onset CH.

Abstract
OBJECTIVE The American College of Obstetrics threshold for hypertension (≥140/90 mm Hg) differs from those of the American College of Cardiology (ACC) and the American Heart Association (AHA). It is unknown if ACC/AHA hypertension levels are associated with adverse pregnancy outcomes (APOs) after 20 weeks gestation. The purpose of this study is to analyze APOs in women with blood pressure (BP) in the elevated or stage 1 range after 20 weeks gestation. STUDY DESIGN This was a secondary analysis of the nuMoM2b prospective cohort study of 10,038 nulliparous, singleton pregnancies between 2010 and 2014. BP was measured at three visits during the pregnancy using a standard protocol. Women without medical comorbidities, with normal BP by ACC/AHA guidelines (systolic BP [SBP] < 120 and diastolic BP [DBP] < 80 mm Hg) up to 22 weeks, were included. Exposure was BP between 22 and 29 weeks gestation: normal (SBP < 120 and DBP < 80 mm Hg), elevated (SBP: 120-129 and DBP < 80 mm Hg), and stage 1 (SBP: 130-139 or DBP: 80-89 mm Hg). The primary outcome was hypertensive disorder of pregnancy (HDP) at delivery. Secondary outcomes included fetal growth restriction (FGR), placental abruption, preterm delivery, and cesarean delivery. Multivariable-adjusted odds ratio (aORs) and 95% confidence intervals (CIs) were estimated using logistic regression models. RESULTS Of 4,460 patients that met inclusion criteria, 3,832 (85.9%) had BP in the normal range, 408 (9.1%) in elevated, and 220 (4.9%) in stage 1 range between 22 and 29 weeks. The likelihood of HDP was significantly higher in women with elevated BP (aOR 1.71, 95%CI: 1.18,2.48), and stage 1 BP (aOR: 2.79, 95%CI: 1.84,4.23) compared to normal BP (p < 0.001). Stage 1 BP had twice odds of FGR (aOR: 2.33, 95%CI: 1.22,4.47) and elevated BP had three times odds of placental abruption (aOR: 3.03; 95%CI: 1.24,7.39). CONCLUSION Elevated or stage 1 BP >20 weeks of pregnancy are associated with HDP, FGR, and placental abruption. KEY POINTS · Elevated and stage 1 BP increases risk for HDP.. · Elevated BP increases risk for placental abruption.. · Stage 1 BP increases risk for FGR..

Abstract
INTRODUCTION The primary concern for women who have experienced peripartum cardiomyopathy (PPCM) is the safety of a subsequent pregnancy (SSP). To maximie decision-making, facilitate effective patient counselling, and ultimately improve maternal and fetal outcomes as a whole, it is critical to comprehend the outcomes of SSP in women who have previously experienced PPCM. This study aimed to evaluate the outcomes of SSP in women with PPCM. METHODS Three databases (PubMed, Scopus, and ScienceDirect) were used to identify relevant studies prior to 17 October 2023. A total of 662 studies were reviewed. Following the abstract and full-text screenings, 18 observational studies were included, out of which 2 were deemed suitable for inclusion in this meta-analysis. The quality assessment was conducted using the Newcastle-Ottawa Scale. RESULTS This study has a total of 487 SSPs. Although recovered left ventricular (LV) function before entering SSP has the potential to be a beneficial prognostic factor, recovered LV function still has a substantial risk of relapse. The mortality rate of PPCM in an SSP ranged from 0% to 55.5%. Persistent LV dysfunction was significantly associated with an increased mortality rate (OR 13.17; 95% CI 1.54 to 112.28; p=0.02) and lower LV ejection fraction (MD -12.88; 95% CI -21.67 to -4.09; p=0.004). Diastolic and right ventricular functions remained unchanged before SSP and at follow-up. The majority of the SSP was observed alongside hypertension, while pre-eclampsia emerged as the predominant hypertensive complication in most studies. CONCLUSION SSP increases the risk of relapse and mortality in women with a previous history of PPCM. Persistent LV dysfunction prior to the SSP has a higher mortality risk compared with recovered LV function. SSP was also associated with the worsening of LV echocardiography parameters.

Advani R, Chandrasekaran S. Chronic hypertension diagnosed by the American Heart Association and American College of Cardiology criteria is associated with increased risk of developing hypertensive disorders of pregnancy. Am J Obstet Gynecol MFM 2024; 6:101269. [PMID: 38145820 DOI: 10.1016/j.ajogmf.2023.101269] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Revised: 12/19/2023] [Accepted: 12/19/2023] [Indexed: 12/27/2023]
Abstract
BACKGROUND ACOG uses a systolic blood pressure (SBP) ≥140 or diastolic blood pressure (DBP) ≥90 documented at <20 weeks of gestation to define chronic hypertension. In the nonpregnant state, the American Heart Association (AHA) and the American College of Cardiology (ACC) define chronic hypertension using lower diagnostic thresholds of SBP ≥130 or DBP ≥80. It remains unclear whether using more conservative guidelines in pregnancy improves identification of those at risk for gestational hypertension (GHTN) or preeclampsia (PRE). OBJECTIVE We sought to investigate whether subjects with chronic hypertension based on the American Heart Association and American College of Cardiology criteria had an increased risk for gestational hypertension and preeclampsia than those without chronic hypertension. STUDY DESIGN We conducted a retrospective cohort study utilizing a clinical database at a diverse, large urban, safety-net hospital. Subjects aged 18 to 40 years with singleton gestations and first trimester prenatal care were included. We defined subjects that met the criteria for stage 1 chronic hypertension based on first trimester systolic blood pressure and diastolic blood pressure cutoffs satisfying the American Heart Association and American College of Cardiology criteria (systolic blood pressure ≥130 mm Hg or diastolic blood pressure ≥80 mm Hg). Those who did not meet these criteria had a systolic blood pressure <130 mm Hg and a diastolic blood pressure <90 mm Hg. We did not include those with chronic hypertension based on the American College of Obstetricians and Gynecologists criteria in this cohort (systolic blood pressure ≥140 mm Hg or diastolic blood pressure ≥90 mm Hg at <20 weeks); therefore, those who met the American Heart Association and American College of Cardiology criteria solely consisted of subjects with systolic blood pressure of 130 to 139 mm Hg and diastolic blood pressure of 80 of 89 mm Hg. By doing this, we were able to specifically investigate the increased risk for this specific population, which remains unclear. Diagnoses of gestational hypertension and preeclampsia were based on the established American College of Obstetricians and Gynecologists criteria. Preeclampsia included those with and without severe features. Tests for normality were performed. Student t-tests or rank sum tests were performed as appropriate for continuous variables; chi-square or Fisher's exact tests were performed for categorical variables. Generalized linear models were performed to calculate risk ratios while controlling for appropriate confounders. RESULTS Of N=3354 subjects, 18% (n=629) were diagnosed with stage 1 chronic hypertension based on American Heart Association and American College of Cardiology criteria. Those with American Heart Association and American College of Cardiology stage 1 chronic hypertension had increased rates of gestational hypertension (35.4% vs 20%; P<.001) and preeclampsia (22.3% vs 10%; P<.001) than those without Stage 1 chronic hypertension based on these criteria. When controlling for maternal age, race, first trimester body mass index, pregestational diabetes, and substance use, those with the American Heart Association and American College of Cardiology stage 1 chronic hypertension had an almost 1.5-fold higher adjusted risk ratio of experiencing gestational hypertension (adjusted risk ratio, 1.49±0.10; P<.001) and almost 2-fold increased adjusted risk ratio of experiencing preeclampsia (adjusted risk ratio, 1.98±0.19; P<.001). CONCLUSION Our data suggest an increased risk for developing gestational hypertension and preeclampsia for subjects satisfying the American Heart Association and American College of Cardiology cutoff for stage 1 chronic hypertension. Future studies need to consider whether diagnosis of chronic hypertension in pregnancy should conform with American Heart Association and American College of Cardiology criteria, and if those with stage 1 chronic hypertension based on American Heart Association and American College of Cardiology criteria require the same preventative measures and interventions utilized by those diagnosed by American College of Obstetricians and Gynecologists criteria.

Abstract
In recent years, the American College of Cardiology and the American Heart Association have reduced the thresholds for a hypertension diagnosis among nonpregnant adults. This change has led to more individuals with reproductive potential to be labeled as being chronically hypertensive, and some were started on antihypertensive medications. When these individuals become pregnant, the obstetrical care provider will have to decide whether to manage them as individuals with chronic hypertensive when only a few years ago they would have been managed as normotensive individuals and when the evidence regarding treatment of these patients during pregnancy is limited. If implemented widely, the management of patients with stage 1 hypertension similar to the traditional chronic hypertension will likely lead to additional maternal and fetal testing, to an increase in hospital admissions, and potentially to unnecessary interventions, such as preterm birth. Our goal was to compile the existing evidence regarding the pregnancy outcomes among patients with stage 1 hypertension to assist providers in their diagnosis and management of this patient group.

Abstract
OBJECTIVE Prepregnancy optimization of cardiovascular function may reduce the risk of pre-eclampsia. We aimed to assess the feasibility and effect of preconception cardiovascular monitoring, exercise, and beetroot juice on cardiovascular parameters in women planning to conceive. DESIGN AND METHOD Prospective single-site, open-label, randomized controlled trial. Thirty-two women, aged 18-45 years, were allocated into one of four arms (1 : 1 : 1 : 1): exercise, beetroot juice, exercise plus beetroot juice and no intervention for 12 weeks. Blood pressure (BP) was measured at home daily. Cardiac output ( CO ) and total peripheral resistance (TPR) were assessed via bio-impedance. RESULTS Twenty-nine out of 32 (91%) participants completed the study. Adherence to daily BP and weight measurements were 81% and 78%, respectively ( n = 29). Eight out of 15 (53%) of participants did not drink all the provided beetroot juice because of forgetfulness and taste. After 12 weeks, exercise was associated with a reduction in standing TPR (-278 ± 0.272 dynes s cm -5 , P < 0.05), and an increase in standing CO (+0.88 ± 0.71 l/min, P < 0.05). Exercise and beetroot juice together was associated with a reduction in standing DBP ( 7 ± 6 mmHg, P < 0.05), and an increase in standing CO (+0.49 ± 0.66 l/min, P < 0.05). The control group showed a reduction in standing TPR ( 313 ± 387 dynes s cm -5 ) and standing DBP ( 8 ± 5mmHg). All groups gained weight. CONCLUSION Exercise and beetroot juice in combination showed a signal towards improving cardiovascular parameters. The control group showed improvements, indicating that home measurement devices and regular recording of parameters are interventions in themselves. Nevertheless, interventions before pregnancy to improve cardiovascular parameters may alter the occurrence of hypertensive conditions during pregnancy and require further investigation in adequately powered studies.

Perinatal outcomes in women with lower-range elevated blood pressure and stage 1 hypertension: insights from the Kaya health and demographic surveillance system, Burkina Faso. BMC Public Health 2023; 23:2539. [PMID: 38114971 PMCID: PMC10729335 DOI: 10.1186/s12889-023-17424-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Accepted: 12/06/2023] [Indexed: 12/21/2023] Open
Abstract
BACKGROUND The impact of lower thresholds for elevated blood pressure (BP) on adverse perinatal outcomes has been poorly explored in sub-Saharan African populations. We aimed to explore the association between lower BP cutoffs (according to the 2017 American College of Cardiology/American Heart Association [ACC/AHA] criteria) and adverse perinatal outcomes in Kaya, Burkina Faso. METHODS This retrospective cohort study included 2,232 women with singleton pregnancies between February and September 2021. BP was categorized according to the ACC/AHA criteria and applied throughout pregnancy. A multivariable Poisson regression model based on Generalized Estimating Equation with robust standard errors was used to evaluate the association between elevated BP, stage 1 hypertension, and adverse perinatal outcomes, controlling for maternal sociodemographic characteristics, parity, and the number of antenatal consultations, and the results were presented as adjusted risk ratios (aRRs) with corresponding 95% confidence intervals (CIs). RESULTS Of the 2,232 women, 1000 (44.8%) were normotensive, 334 (14.9%) had elevated BP, 759 (34.0%) had stage 1 hypertension, and 139 (6.2%) had stage 2 hypertension. There was no significant association between elevated BP and adverse pregnancy outcomes. Compared to normotensive women, women with elevated BP had a 2.05-fold increased risk of delivery via caesarean section (aRR;2.05, 95%CI; 1.08-3.92), while those with stage 1 hypertension had a 1.41-fold increased risk of having low birth weight babies (aRR; 1.41, 95%CI; 1.06-1.86), and a 1.32-fold increased risk of having any maternal or neonatal adverse outcome (aRR; 1.32, 95%CI; 1.02-1.69). CONCLUSIONS Our results suggest that the risk of adverse pregnancy outcomes is not increased with elevated BP. Proactive identification of pregnant women with stage 1 hypertension in Burkina Faso can improve hypertension management through enhanced clinical surveillance.

Abstract
OBJECTIVE To evaluate the association between maternal blood pressure (BP) below 130/80 mm Hg compared with 130-139/80-89 mm Hg and pregnancy outcomes. METHODS We conducted a planned secondary analysis of CHAP (Chronic Hypertension and Pregnancy), an open label, multicenter, randomized controlled trial. Participants with mean BP below 140/90 mm Hg were grouped as below 130/80 mm Hg compared with 130-139/80-89 mm Hg by averaging postrandomization clinic BP throughout pregnancy. The primary composite outcome was preeclampsia with severe features, indicated preterm birth before 35 weeks of gestation, placental abruption, or fetal or neonatal death. The secondary outcome was small for gestational age (SGA). RESULTS Of 2,408 patients in CHAP, 2,096 met study criteria; 1,328 had mean BP 130-139/80-89 mm Hg and 768 had mean BP below 130/80 mm Hg. Participants with mean BP below 130/80 mm Hg were more likely to be older, on antihypertensive medication, in the active treatment arm, and to have lower BP at enrollment. Mean clinic BP below 130/80 mm Hg was associated with lower frequency of the primary outcome (16.0% vs 35.8%, adjusted relative risk 0.45; 95% CI 0.38-0.54) as well as lower risk of severe preeclampsia and indicated birth before 35 weeks of gestation. There was no association with SGA. CONCLUSION In pregnant patients with mild chronic hypertension, mean BP below 130/80 mm Hg was associated with improved pregnancy outcomes without increased risk of SGA.

Abstract
BACKGROUND Recent studies suggest that low-dose acetylsalicylic acid (ASA) can lower pregnancy-associated morbidity. METHODS This review is based on pertinent publications that were retrieved by a selective search in PubMed, with special attention to systematic reviews, metaanalyses, and randomized controlled trials. RESULTS Current meta-analyses document a reduction of the risk of the occurrence of pre-eclampsia (RR 0.85, NNT 50), as well as beneficial effects on the rates of preterm birth (RR 0.80, NNT 37), fetal growth restriction (RR 0.82, NNT 77), and perinatal death (RR 0.79, NNT 167). Moreover, there is evidence that ASA raises the rate of live births after a prior spontaneous abortion, while also lowering the rate of spontaneous preterm births (RR 0.89, NNT 67). The prerequisites for therapeutic success are an adequate ASA dose, early initiation of ASA, and the identification of women at risk of pregnancy-associated morbidity. Side effects of treatment with ASA in this patient group are rare and mainly involve bleeding in connection with the pregnancy (RR 0.87, NNH 200). CONCLUSION ASA use during pregnancy has benefits beyond reducing the risk of pre-eclampsia. The indications for taking ASA during pregnancy may be extended at some point in the future; at present, in view of the available evidence, it is still restricted to high-risk pregnancies.

Abstract
BACKGROUND Sub-optimal medication adherence in pregnant women with chronic disease and pregnancy-related indications has the potential to adversely affect maternal and perinatal outcomes. Adherence to appropriate medications is advocated during and when planning pregnancy to reduce risk of adverse perinatal outcomes relating to chronic disease and pregnancy-related indications. We aimed to systematically identify effective interventions to promote medication adherence in women who are pregnant or planning to conceive and impact on perinatal, maternal disease-related and adherence outcomes. METHODS Six bibliographic databases and two trial registries were searched from inception to 28th April 2022. We included quantitative studies evaluating medication adherence interventions in pregnant women and women planning pregnancy. Two reviewers selected studies and extracted data on study characteristics, outcomes, effectiveness, intervention description (TIDieR) and risk of bias (EPOC). Narrative synthesis was performed due to study population, intervention and outcome heterogeneity. RESULTS Of 5614 citations, 13 were included. Five were RCTs, and eight non-randomised comparative studies. Participants had asthma (n = 2), HIV (n = 6), inflammatory bowel disease (IBD; n = 2), diabetes (n = 2) and risk of pre-eclampsia (n = 1). Interventions included education +/- counselling, financial incentives, text messaging, action plans, structured discussion and psychosocial support. One RCT found an effect of the tested intervention on self-reported antiretroviral adherence but not objective adherence. Clinical outcomes were not evaluated. Seven non-randomised comparative studies found an association between the tested intervention and at least one outcome of interest: four found an association between receiving the intervention and both improved clinical or perinatal outcomes and adherence in women with IBD, gestational diabetes mellitus (GDM), and asthma. One study in women with IBD reported an association between receiving the intervention and maternal outcomes but not for self-reported adherence. Two studies measured only adherence outcomes and reported an association between receiving the intervention and self-reported and/or objective adherence in women with HIV and risk of pre-eclampsia. All studies had high or unclear risk of bias. Intervention reporting was adequate for replication in two studies according to the TIDieR checklist. CONCLUSIONS There is a need for high-quality RCTs reporting replicable interventions to evaluate medication adherence interventions in pregnant women and those planning pregnancy. These should assess both clinical and adherence outcomes.

Abstract
OBJECTIVE The aim of the study is to determine whether stage 1 hypertension is a risk factor for cesarean at ≥390/7 weeks. STUDY DESIGN This is a retrospective cohort study of nulliparas delivering at ≥390/7weeks. Exposure was defined as stage 1 hypertension and compared with normotension. The primary outcome was unplanned cesarean. Statistical analysis was performed using SPSS 27. RESULTS Two hundred and fifty patients had stage 1 hypertension and 250 had normotension. Thirty-eight percent of the patients with stage 1 hypertension required cesarean as did 22% of controls (risk ratio [RR]=1.55, 95% confidence interval [CI]: 1.23-1.96, p <0.001). This remained significant after controlling for confounders in a logistic regression (odds ratio [OR]=1.61, 95% confidence interval [CI]: 1.02-2.55, p <0.040). Upon secondary analysis, these results were statistically significant for gestational age ≥395/7 weeks (adjusted odds ratio [AOR]=1.89, 95% CI: 1.05-3.39, p=0.033) but not from 390/7 to 394/7weeks (AOR=0.68, 95% CI: 0.31-1.50, p=0.34). CONCLUSION In nulliparas, stage 1 hypertension is an independent risk factor for unplanned cesarean. KEY POINTS · Stage 1 hypertension correlates with more cesareans.. · Unplanned cesarean for nonreassuring fetal status correlates with impaired placental function.. · Stages 1 and 2 hypertension carry similar risks..

Abstract
OBJECTIVE A relationship between the 2017 American College of Cardiology and American Heart Association blood pressure thresholds and adverse pregnancy outcomes has been reported, but few studies have explored the diagnostic test properties of these cutoffs when used within pregnancy. DATA SOURCES Electronic databases were searched (2017-2021) for measurements of blood pressure in pregnancy at >20 weeks, classified according to the 2017 American College of Cardiology and American Heart Association criteria, and their relationship with pregnancy outcomes. Blood pressure was categorized as "normal" (systolic blood pressure of <120 mm Hg and diastolic blood pressure of <80 mm Hg), "elevated blood pressure" (systolic blood pressure of 120-129 mm Hg and diastolic blood pressure of <80 mm Hg), "stage 1 hypertension" (systolic blood pressure of 130-139 mm Hg and/or diastolic blood pressure of 80-89 mm Hg), and "stage 2 hypertension" (systolic blood pressure of ≥140 mm Hg and/or diastolic blood pressure of ≥90 mm Hg). STUDY ELIGIBILITY CRITERIA Studies recording blood pressure at or above 20 weeks gestation were included. METHODS Meta-analyses were used to investigate the strength of the association between blood pressure cutoffs and adverse outcomes, and the diagnostic test properties were calculated accounting for gestation. RESULTS There were 12 included studies. The American College of Cardiology or American Heart Association blood pressure categories were determined from peak blood pressures at any point from 20 weeks of gestation and at specific gestational ages (20-27, 28-32, or 33-36 weeks of gestation), as available. A higher (vs normal) blood pressure category was consistently associated with adverse outcomes. The strength of association between blood pressure categories and adverse outcomes was the greatest with "stage 2 hypertension" (blood pressure of ≥140/90 mm Hg). The results were similar when peak blood pressure was reported either at any time from 20 weeks of gestation or within gestational age groups (as above). No blood pressure category was useful as a diagnostic "rule-out test" for adverse outcomes, as all negative likelihood ratios were ≥0.2. Only "stage 2 hypertension" was useful as a "rule in-test," with positive likelihood ratios of ≥5.0, for maximum blood pressure at >20 weeks of gestation for preeclampsia and blood pressure within any gestational age groups for preeclampsia, eclampsia, stroke, maternal death, and stillbirth. CONCLUSION From 20 weeks of gestation, blood pressure thresholds of 140 mm Hg (systolic) and 90 mm Hg (diastolic) were useful in identifying women at increased risk of adverse pregnancy outcomes, irrespective of the specific gestational age at blood pressure measurement. Lowering the blood pressure threshold for abnormal blood pressure at >20 weeks of gestation would not assist clinicians in identifying women at heightened maternal or perinatal risk. No American College of Cardiology or American Heart Association blood pressure threshold can provide reassurance that women are unlikely to develop adverse outcomes.

Abstract
OBJECTIVES To synthesize the evidence from randomized controlled trials (RCTs) of antihypertensive treatment for mild pregnancy hypertension. METHODS We searched various databases from inception to June 2022, using keywords including hypertension; pregnancy; therapy; treatment; pregnancy outcomes; maternal outcomes; and perinatal outcomes. Only RCTs of antihypertensive treatment for mild hypertension in pregnancy comparing placebo/no therapy were included. We used Review Manager version 5.3 for statistical analyses. RESULTS In all, eight studies were eligible, with a total of 4211 participants. Compared with control, the active treatment significantly prevented preeclampsia (OR 0.55; 95%CI, 0.39-0.78), placental abruption (OR 0.39; 95%CI, 0.17-0.91), severe hypertension (OR 0.35; 95%CI, 0.17-0.71), end-organ dysfunction (OR 0.34; 95%CI, 0.19-0.62) and preterm birth (OR 0.69; 95%CI, 0.59-0.82), with no increased risk of small for gestational age (SGA) (OR 1.25; 95%CI, 0.78-2.00), or admission to the NICU (OR 0.83; 95%CI, 0.54-1.28). Subgroup analyses demonstrated that the tight control group did not show an advantage over the less-tight control group in improving pregnancy outcomes. CONCLUSION In pregnant women with mild pregnancy-induced hypertension or chronic hypertension, antihypertensive treatment still provided precise benefits of improving pregnancy outcomes without increased risk in fetal outcomes.

Abstract
Objective The aim of this study was to evaluate the impact on perinatal outcomes related to placental insufficiency with the application of the new 2017 ACC/AHA guidelines to a group of chronic hypertensive pregnancies during their first-trimester assessment. Study design This retrospective cohort study included pregnancies with preconceptional hypertension and known perinatal outcomes. In the first trimester, a combined screening for preterm preeclampsia (p-PE) was performed, including blood pressure (BP), mean uterine artery Doppler, and maternal characteristics. Patients were divided, according to the 2017 ACC/AHA consensus, into the following groups: elevated or less, Stage 1, and Stage 2. For adverse perinatal outcome assessment, univariate and multivariate regression analyses were performed, considering the "elevated or less" group as a reference. Odds ratios (OR) were compared with linear trend analysis. The main outcomes measured were preterm PE and FGR < 3 rd percentile. Results Of the 130 included patients, 59 (45.4%) were classified as elevated or less, 47 (36.2%) as Stage 1, and 24 (18.4%) as Stage 2. p-PE showed a significant increase according to BP range [7% (OR = 1.0), 19.6% (OR = 3.2), and 21.7% (OR = 3.7)]; trend p = 0.02, for elevated or less, Stage 1, and Stage 2, respectively. There was a non-significant increased trend of FGR < 3 rd percentile according to the BP stage. The best multivariate predictive model for p-PE included a previous PE background (OR = 15) and mean arterial pressure in mmHg (OR = 1.1). Conclusion The use of the 2017 ACC/AHA consensus in pregnancies with chronic hypertension identifies an intermediate risk group for placental-mediated diseases.

American College of Cardiology and American Heart Association blood pressure categories-a systematic review of the relationship with adverse pregnancy outcomes in the first half of pregnancy. Am J Obstet Gynecol 2022; 228:418-429.e34.

Abstract
OBJECTIVE A relationship between the 2017 American College of Cardiology and American Heart Association blood pressure thresholds and adverse pregnancy outcomes has been reported, but few studies have explored the diagnostic test properties of these cutoffs. DATA SOURCES We systematically searched electronic databases (from 2017 to 2021) for reports of blood pressure measurements in pregnancy, classified according to 2017 American College of Cardiology and American Heart Association criteria, and their relationship with pregnancy outcomes. STUDY ELIGIBILITY CRITERIA Studies recording blood pressure at <20 weeks gestation were included. METHODS Meta-analyses were used to investigate the strength of the association between blood pressure cutoffs and adverse outcomes, and the diagnostic test properties were calculated. RESULTS Of 23 studies included, there was a stepwise relationship between the American College of Cardiology and American Heart Association blood pressure category (when compared with normal blood pressure of <120/80 mmHg) and the strength of the association with preeclampsia. The category of elevated blood pressure had a risk ratio of 2.0 (95% prediction interval, 0.8-4.8), the stage 1 hypertension category had a risk ratio of 3.0 (95% prediction interval, 1.1-8.5), and the stage 2 hypertension category had a risk ratio of 7.9 (95% prediction interval, 1.8-35.1). Between-study variability was related to the magnitude of the association with stronger relationships in larger studies at low risk of bias and with unselected populations with multiple routine blood pressure measurements. None of the systolic blood pressure measurements of <120 mmHg, <130/80 mmHg, or <140/90 mmHg were useful to rule out the development of preeclampsia (all negative likelihood ratios >0.2). Only a blood pressure measurement of ≥140/90 mmHg was a good predictor for the development of preeclampsia (positive likelihood ratio, 5.95). The findings were similar for other outcomes. CONCLUSION Although a blood pressure of 120 to 140 over 80 to 90 mmHg at <20 weeks gestation is associated with a heightened risk for preeclampsia and adverse pregnancy outcomes and may assist in risk prediction in multivariable modelling, lowering the diagnostic threshold for chronic hypertension would not assist clinicians in identifying women at heightened risk.

Abstract
The objective of this population-based retrospective study was to determine the effect of the updated hypertension definition by the American College of Cardiology (ACC) and the American Heart Association (AHA) on the prevalence of chronic hypertension (CHTN) diagnosis in pregnancy. The pre-ACC/AHA group (N = 14,505,399) consisted of births between 2013 and 2016 and the post-ACC/AHA group (N = 7,269,010) consisted of births between 2018 and 2019. After adjusting for differences between groups, CHTN diagnosis was more common in the post-ACC/AHA group (p < 0.001). In conclusion, the prevalence of CHTN diagnosis in pregnancy increased after the new ACC/AHA guidelines publication.

Abstract
BACKGROUND Chronic hypertension during pregnancy is associated with increased risk of adverse birth outcomes. In 2017, the American College of Cardiology and American Heart Association (ACC/AHA) lowered thresholds to classify hypertension in non-pregnant adults to SBP ≥ 130 mmHg and DBP ≥ 80 mmHg (ie stage I hypertension), resulting in an additional 4.5-million reproductive-aged women meeting criteria for hypertension. Little is known about effects of pre-pregnancy blood pressure (BP) in this range. OBJECTIVES To examine the effect of pre-pregnancy maternal BP on preterm delivery. METHODS We analysed the data from two waves of the National Longitudinal Study of Adolescent to Adult Health, including participants that had measured BP at Wave IV (2008-09) and a pregnancy that resulted in a singleton live birth between Waves IV and V (2016-18; n = 2038). We categorised BP using ACC/AHA cut-offs: normal (SBP < 120 mmHg and DBP < 80 mmHg), elevated (SBP 120-129 mmHg and DBP < 80 mmHg), hypertension stage I (SBP 130-139 mmHg or DBP 80-89 mmHg) and hypertension stage II (SBP ≥ 140 mmHg or DBP ≥ 90 mmHg). We estimated risk ratios (RR) with log-binomial regression adjusting for maternal demographics, anthropometrics and medication use. RESULTS The prevalence of preterm delivery was 12.6%. A standard deviation (SD) increment in SBP (SD = 12.2 mmHg) and DBP (SD = 9.3 mmHg) was associated with a 14% (95% confidence interval [CI] 2, 27) and 20% (95% CI 4, 37) higher risk of preterm delivery. Compared to normotensive controls, stage I (RR 1.33, 95% CI 1.01, 1.74) and stage II (RR 1.34, 95% CI 0.89, 2.00) hypertension were associated with increased risk. CONCLUSIONS We observed greater risk of preterm delivery among women with higher pre-pregnancy BP. Women with stage I hypertension during pregnancy may benefit from increased BP monitoring. Additional studies on the utility of foetal surveillance in this group are warranted.

Abstract
Chronic hypertension complicates 1% to 2% of pregnancies, and it is increasingly common. Women with chronic hypertension are an easily recognized group who are in touch with a wide variety of healthcare providers before, during, and after pregnancy, mandating that chronic hypertension in pregnancy be within the scope of many practitioners. We reviewed recent data on management to inform current care and future research. This study is a narrative review of published literature. Compared with normotensive women, women with chronic hypertension are at an increased risk of maternal and perinatal complications. Women with chronic hypertension who wish to be involved in their care can do by measuring blood pressure at home. Accurate devices for home blood pressure monitoring are now readily available. The diagnostic criteria for superimposed preeclampsia remain problematic because most guidelines continue to include deteriorating blood pressure control in the definition. It has not been established how angiogenic markers may aid in confirmation of the diagnosis of superimposed preeclampsia when suspected, over and above information provided by routinely available clinical data and laboratory results. Although chronic hypertension is a strong risk factor for preeclampsia, and aspirin decreases preeclampsia risk, the effectiveness specifically among women with chronic hypertension has been questioned. It is unclear whether calcium has an independent effect in preeclampsia prevention in such women. Treating hypertension with antihypertensive therapy halves the risk of progression to severe hypertension, thrombocytopenia, and elevated liver enzymes, but a reduction in preeclampsia or serious maternal complications has not been observed; however, the lack of evidence for the latter is possibly owing to few events. In addition, treating chronic hypertension neither reduces nor increases fetal or newborn death or morbidity, regardless of the gestational age at which the antihypertensive treatment is started. Antihypertensive agents are not teratogenic, but there may be an increase in malformations associated with chronic hypertension itself. At present, blood pressure treatment targets used in clinics are the same as those used at home, although blood pressure values tend to be inconsistently lower at home among women with hypertension. Although starting all women on the same antihypertensive medication is usually effective in reducing blood pressure, it remains unclear whether there is an optimal agent for such an approach or how best to use combinations of antihypertensive medications. An alternative approach is to individualize care, using maternal characteristics and blood pressure features beyond blood pressure level (eg, variability) that are of prognostic value. Outcomes may be improved by timed birth between 38 0/7 and 39 6/7 weeks' gestation based on observational literature; of note, confirmatory trial evidence is pending. Postnatal care is facilitated by the acceptability of most antihypertensives (including angiotensin-converting enzymes inhibitors) for use in breastfeeding. The evidence base to guide the care of pregnant women with chronic hypertension is growing and aligning with international guidelines. Addressing outstanding research questions would inform personalized care of chronic hypertension in pregnancy.

Abstract
OBJECTIVE To determine the clinical efficacy of aspirin combined with labetalol on gestational hypertension (GH) and its influence on serum pregnancy associated plasma protein-A (PAPP-A), adiponectin (APN), and high mobility group box-1 (HMGB1). METHODS A total of 146 patients with GH admitted to the Zibo Central Hospital between April 2018 and January 2020 were analyzed retrospectively. The control group (Con group, n=71) was treated by labetalol monotherapy, and on this basis, the research group (Res group, n=75) was additionally given aspirin. The following criteria of the 2 groups were evaluated: total effectiveness rate, incidence of adverse reactions, blood pressure-associated indices, coagulation function-associated indices, changes in serum PAPP-A, APN, and HMGB1 levels, adverse maternal and infant outcomes, and neonatal Apgar score. RESULTS After therapy, the Res group showed a notably higher total effective rate than the Con group, with no remarkable difference in the incidence of adverse reactions. Additionally, compared to the Con group, the Res group showed notably lower systolic blood pressure (SBP) and diastolic blood pressure (DBP), greatly improved coagulation function, significantly lower levels of serum PAPP-A and HMGB1, and significantly higher level of serum APN. Moreover, the incidence of adverse maternal and infant outcomes in the Res group was much lower than that in the Con group after therapy, and the one- and five-min Apgar scores of neonates in the Res group were both notably higher than those in the Con group after delivery. CONCLUSION For patients with GH, aspirin combined with labetalol can effectively control blood pressure, improve coagulation function and clinical efficacy, lower serum PAPP-A and HMGB1, and increase serum APN, and ameliorate maternal and infant outcome.

Abstract
Gestational hypertensive complications are preceded by deviant hemodynamic adjustments affecting blood pressure. Our objective was to determine the timing and magnitude of changes in blood pressure during singleton normotensive and hypertensive pregnancies. PubMed (NCBI) and Embase (Ovid) databases were searched for relevant studies up to November 2019. Studies reporting original blood pressure measurements during pregnancy together with a non-pregnant reference measurement were included. Studies including women with a history of cardiovascular or metabolic disease, or women using antihypertensive drugs were excluded. Pooled mean differences between pregnant and non-pregnant women, and absolute blood pressure values were calculated for predefined gestational intervals in normotensive and hypertensive pregnancy, using a random-effects model. Meta-regression analysis was used to analyze group differences in adjustments. In early normotensive pregnancy, both systolic and diastolic blood pressure decreased, reaching their maximum reduction of -4 mmHg (95%CI -6 to -1 mmHg) and -4 mmHg (95%CI, -5 to -3 mmHg), respectively in the second trimester. Thereafter, blood pressure gradually increased towards non-pregnant values. All absolute blood pressure measurements throughout normotensive pregnancy were below 130/80 mmHg. In hypertensive pregnancies, only diastolic blood pressure decreased early in pregnancy. In conclusion, this meta-analysis showed a clinically moderate, but significant mid-pregnancy drop in blood pressure during normotensive pregnancy. Reference curves with absolute values underscore the current liberal cut-off limit for gestational hypertension. A lack of a mid-pregnancy systolic blood pressure drop might reflect increased vascular resistance in women destined to develop hypertensive pregnancy complications.

[PMID: 35049195 PMCID: PMC9191338 DOI: 10.1097/md.0000000000027916] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2021] [Accepted: 11/08/2021] [Indexed: 11/26/2022] Open
Abstract
INTRODUCTION Aspirin is widely used to prevent pregnancy related vascular disorders such as preeclampsia (PE), intrauterine growth restriction and maternal disorders. However, the indications for the use of aspirin during pregnancy is currently controversial because the dosage of aspirin used and the sample sizes in various studies differ considerably. Furthermore, women of African ancestry are more likely to have higher rates of PE and more severe cases than those of their Caucasian counterparts. Yet, there are very few studies in this population group. Therefore, the aim of this review will be to determine the effect of low-dose aspirin (LDA) for prevention of PE in women of African ancestry. METHODS AND ANALYSIS This is a protocol for a systematic review and meta-analysis of published studies on the effect of LDA for prevention of PE. Relevant information will be accessed from the following databases; PubMed, Cochrane Central Register of Controlled Trials, Google Scholar, Google, EBSCO Host, and the Web of Science. The studies will be mapped in 2 stages: stage 1 will map studies descriptively by focus and method; stage 2 will involve additional inclusion criteria, quality assessment and data extraction undertaken by 2 reviewers in parallel. Evidence will be synthesized using relevant systematic research tools. Meta-analysis and subgroup analysis will be conducted using RevMan whilst Stata 13 will be used for meta-regressions. We will follow recommendations described in the preferred reporting items for systematic reviews and meta-analyses statement and the Cochrane Handbook for Intervention Reviews. DISCUSSION The use of LDA as a prophylactic treatment has been considered for the prevention of PE. However, studies evaluating the use of LDA in women of African ancestry are few. Therefore, with the increase in the prevalence of PE in the African population, it is critical to further investigate the use of LDA in pregnant women of African ancestry. ETHICS AND DISSEMINATION The review and meta-analysis will not require ethical approval and the findings will be published in peer-reviewed journals and presented at local and international conferences. The findings of this review will inform all stakeholders on current and future guidelines on the use of aspirin in pregnancy, especially in populations of African ancestry. SYSTEMATIC REVIEW REGISTRATION International prospective Register of Systematic Reviews (PROSERO) number: (CRD42020213213).

Abstract
BACKGROUND To explore whether elevated blood pressure and stage 1 hypertension were risks to GH and PE occurrence by a meta-analysis. METHODS Electronic databases were searched systematically up to Dec 2020. Combined risk ratio (RR) and 95%CI were used to evaluate the relationship between two blood pressure groups and GH and PE. RESULTS Seven studies were included in this study. In elevated blood pressure group, the overall RR of GH group is 1.93 and the combined RR is 1.98 in PE group. CONCLUSION Elevated BP and stage 1 hypertension were risk factors of GH and PE occurrence in pregnant women.

Blood pressure thresholds in pregnancy for identifying maternal and infant risk: a secondary analysis of Community-Level Interventions for Pre-eclampsia (CLIP) trial data. LANCET GLOBAL HEALTH 2021; 9:e1119-e1128. [PMID: 34237265 PMCID: PMC8295039 DOI: 10.1016/s2214-109x(21)00219-9] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 01/20/2021] [Revised: 04/15/2021] [Accepted: 04/27/2021] [Indexed: 12/13/2022]
Abstract
Background Blood pressure measurement is a marker of antenatal care quality. In well resourced settings, lower blood pressure cutoffs for hypertension are associated with adverse pregnancy outcomes. We aimed to study the associations between blood pressure thresholds and adverse outcomes and the diagnostic test properties of these blood pressure cutoffs in low-resource settings. Methods We did a secondary analysis of data from 22 intervention clusters in the Community-Level Interventions for Pre-eclampsia (CLIP) cluster randomised trials (NCT01911494) in India (n=6), Mozambique (n=6), and Pakistan (n=10). We included pregnant women aged 15–49 years (12–49 years in Mozambique), identified in their community by trained community health workers, who had data on blood pressure measurements and outcomes. The trial was unmasked. Maximum blood pressure was categorised as: normal blood pressure (systolic blood pressure [sBP] <120 mm Hg and diastolic blood pressure [dBP] <80 mm Hg), elevated blood pressure (sBP 120–129 mm Hg and dBP <80 mm Hg), stage 1 hypertension (sBP 130–139 mm Hg or dBP 80–89 mm Hg, or both), non-severe stage 2 hypertension (sBP 140–159 mm Hg or dBP 90–109 mm Hg, or both), or severe stage 2 hypertension (sBP ≥160 mm Hg or dBP ≥110 mm Hg, or both). We classified women according to the maximum blood pressure category reached across all visits for the primary analyses. The primary outcome was a maternal, fetal, or neonatal mortality or morbidity composite. We estimated dose-response relationships between blood pressure category and adverse outcomes, as well as diagnostic test properties. Findings Between Nov 1, 2014, and Feb 28, 2017, 21 069 women (6067 in India, 4163 in Mozambique, and 10 839 in Pakistan) contributed 103 679 blood pressure measurements across the three CLIP trials. Only women with non-severe or severe stage 2 hypertension, as discrete diagnostic categories, experienced more adverse outcomes than women with normal blood pressure (risk ratios 1·29–5·88). Using blood pressure categories as diagnostic thresholds (women with blood pressure within the category or any higher category vs those with blood pressure in any lower category), dose-response relationships were observed between increasing thresholds and adverse outcomes, but likelihood ratios were informative only for severe stage 2 hypertension and maternal CNS events (likelihood ratio 6·36 [95% CI 3·65–11·07]) and perinatal death (5·07 [3·64–7·07]), particularly stillbirth (8·53 [5·63–12·92]). Interpretation In low-resource settings, neither elevated blood pressure nor stage 1 hypertension were associated with maternal, fetal, or neonatal mortality or morbidity adverse composite outcomes. Only the threshold for severe stage 2 hypertension met diagnostic test performance standards. Current diagnostic thresholds for hypertension in pregnancy should be retained.

Abstract
BACKGROUND In 2017, the American College of Cardiology/ American Heart Association (ACC/AHA) guidelines redefined the threshold of high blood pressure (BP) for non-pregnant adults. Several studies aimed to determine whether lowering these thresholds should be considered for pregnancies to prevent poor neonatal outcomes, but the results were inconclusive. METHODS We perform a systematic review and meta-analysis to evaluate the association between BP groups defined by the 2017 ACC/AHA guidelines and pregnancy outcomes. Relevant literature was searched in PubMed, Google Scholar, Embase, and Web of Science up to 18 May 2021. RESULTS Sixteen eligible studies from twelve articles with a total of 303,131 pregnancies were identified, encompassing 233,084, 20,859, 39,379 individuals with normal BP, elevated BP, and stage 1 hypertension, respectively. When compared with normal BP, the combined odds ratio (95% confidence interval) of elevated BP for adverse pregnancy outcomes was not significant; whereas, that of stage 1 hypertension were 1.25 (1.13-1.39), 1.16 (1.03-1.31), 1.50 (1.28-1.77) and 1.12 (1.00-1.25) for preterm delivery, small for gestational age, low birth weight, and early-term delivery, respectively. CONCLUSION Our results indicated that stage 1 hypertension increased the risk of poor neonatal outcomes, highlighting the importance of recognition of stage 1 hypertension as a risk indicator for poor pregnancy outcomes.

Abstract
OBJECTIVE Pregnant women with chronic hypertension are recommended to deliver at 36-396/7 weeks. The American College of Cardiology and American Heart Association in 2017 lowered the blood pressure cut-off for stage I hypertension to 130/80 mm Hg. METHODS We performed a literature review on studies comparing elective induction of labor versus expectant management in pregnant women with chronic hypertension. In addition, we reviewed fetal and maternal outcomes in pregnant women with blood pressure of 120-139/80-89 or 130-139/80-89 mm Hg. RESULTS We found two randomized clinical trials and one retrospective observational study comparing elective delivery of pregnant women with chronic hypertension versus expectant management. The randomized trials favored expectant management and the observational study favored induction of labor. We found 15 retrospective cohort studies analyzing maternal and fetal outcomes in pregnant women with blood pressure cut-off lower than 140/90 mm Hg. There was a consistent finding of increased risk of any hypertensive disorder of pregnancy, gestational diabetes mellitus, and small-for-gestational-age neonate. CONCLUSION Randomized clinical trials are needed to assess the appropriate timing of delivery for women with stage I hypertension with a blood pressure cut-off of 130/80 mm Hg.

Abstract
OBJECTIVE To evaluate maternal and fetal outcomes among women with a single elevated blood pressure before 20 weeks of gestation. METHODS We conducted a retrospective cohort study of women who delivered at Kaiser Permanente Southern California hospitals between January 1, 2008, and December 31, 2019. Participants were divided into two groups: normotensive (all systolic blood pressures lower than 130 mm Hg and diastolic pressures lower than 80 mm Hg) compared with single elevated blood pressure (single systolic pressure 130 mm Hg or higher, diastolic pressure 80 mm Hg or higher, or both). Women with chronic hypertension were excluded. Maternal comorbidities and maternal and neonatal outcomes were extracted from electronic health records using International Classification of Diseases codes. Adjusted odds ratios (aORs) derived from logistic regression were used to describe the magnitude of association. RESULTS Of 303,689 women who delivered during the study period, 23% had a single elevated blood pressure. Rates of hypertensive disorders of pregnancy differed between the two groups (10.6% for single elevated blood pressure, 4.5% for normotensive group; aOR 2.06, 95% CI 2.00-2.13), as did iatrogenic preterm delivery (3.7% vs 2.7%, respectively; aOR 1.27, 95% CI 1.21-1.33). DISCUSSION Women with a single elevated blood pressure before 20 weeks of gestation are at increased risk for hypertensive disorders of pregnancy and iatrogenic preterm delivery.

Abstract
BACKGROUND Hypertension was redefined in 2017 with lower diagnostic thresholds; elevated blood pressure is defined as systolic blood pressure of 120 to 129 mm Hg with diastolic blood pressure of <80 mm Hg and stage 1 hypertension as systolic blood pressure of 130 to 139 mm Hg or diastolic blood pressure of 80 to 89 mm Hg. These guidelines did not include pregnant women. There is limited information on stage 1 hypertension and pregnancy outcomes. OBJECTIVE This study aimed to determine whether elevated blood pressure and stage 1 hypertension as newly defined by the 2017 American College of Cardiology and the American Heart Association guidelines are associated with an increased risk of hypertensive disorders of pregnancy and other adverse maternal and neonatal outcomes. STUDY DESIGN In this retrospective cohort study, 18,801 women with singletons from 2013 to 2019 were categorized as normotensive, prehypertensive (elevated blood pressure), stage 1 hypertensive, or chronic hypertensive. Women with ≥2 systolic blood pressures of 120 to 129 mm Hg before 20 weeks' gestation were classified into the elevated blood pressure group. Women with ≥2 systolic blood pressures of 130 to 139 mm Hg or ≥2 diastolic blood pressures of 80 to 89 mm Hg before 20 weeks' gestation were assigned to the stage 1 hypertension group. Women were classified as chronic hypertensives if they had any of the following: ≥2 systolic blood pressure of ≥140 mm Hg or ≥2 diastolic blood pressure of ≥90 mm Hg before 20 weeks' gestation, a history of chronic hypertension, or antihypertensive medication use before 20 weeks' gestation. Women with pregestational diabetes, lupus, or <2 blood pressures before 20 weeks' gestation were excluded. The association of stage 1 hypertension with the risk of developing hypertensive disorders of pregnancy was estimated using multivariate logistic regression controlling for maternal sociodemographic characteristics, gestational weight gain by prepregnancy body mass index, parity, and aspirin use. Secondary outcomes included subgroups of hypertensive disorders (gestational hypertension, preeclampsia, eclampsia, and hemolysis, elevated liver enzymes, and low platelet count syndrome), gestational diabetes, placental abruption, intrauterine growth restriction, preterm birth, neonatal intensive care unit admission, stillbirth and neonatal death, and maternal intensive care unit admission. All outcomes were adjusted for potential confounders. RESULTS Of the 18,801 women, 13,478 (71.7%) were normotensive, 2659 (14.1%) had elevated blood pressure, 1384 (7.4%) were stage 1 hypertensive, and 1280 (6.8%) were chronic hypertensive. A dose-response relationship was observed: the risk of hypertensive disorders of pregnancy increased from 4.2% in normotensive women to 6.7% (adjusted odds ratio, 1.50; 95% confidence interval, 1.26-1.79) in women with elevated blood pressure, to 10.9% (adjusted odds ratio, 2.54; 95% confidence interval, 2.09-3.08) in women with stage 1 hypertension, and 28.4% (adjusted odds ratio, 7.14; 95% confidence interval, 6.06-8.40) in women with chronic hypertension. Compared with normotensive women, women with stage 1 hypertension had an increased risk of neonatal intensive care unit admissions (15.8% vs 13.0%; adjusted odds ratio, 1.21; 95% confidence interval, 1.03-1.42), preterm birth at <37 weeks' gestation (7.2% vs 5.2%; adjusted odds ratio, 1.45; 95% confidence interval, 1.16-1.81), and gestational diabetes (14.8% vs 6.8%; adjusted odds ratio, 2.68; 95% confidence interval, 2.27-3.17). CONCLUSION Our study demonstrates that elevated blood pressure and stage 1 hypertension, using the 2017 American College of Cardiology and the American Heart Association guideline definition, are associated with increased maternal and neonatal risk. This group of women warrants further investigation to determine whether pregnancy management can be altered to reduce maternal and neonatal morbidity.

Abstract
IMPORTANCE Hypertensive disorders of pregnancy are a leading cause of maternal morbidity and mortality. The impact of applying recent guideline definitions for nonpregnant adults to pregnant women is unclear. OBJECTIVE To determine whether reclassification of hypertensive status using the 2017 American College of Cardiology/American Heart Association (ACC/AHA) guideline definition better identifies women at risk for preeclampsia or eclampsia and adverse fetal/neonatal events compared with the current American College of Obstetricians and Gynecologists (ACOG) definition of hypertension. DESIGN, SETTING, AND PARTICIPANTS This cohort study used electronic medical record data of women who delivered singleton infants between 2009 and 2014 at a large US regional health system. Data analysis was performed from July 2020 to September 2020. EXPOSURE Application of ACC/AHA and ACOG guidelines for the definition of chronic and gestational hypertension. MAIN OUTCOMES AND MEASURES The primary maternal end point was the development of preeclampsia or eclampsia, and the primary fetal/neonatal end point was a composite of preterm birth, small for gestational age, and neonatal intensive care unit admission within 28 days of delivery. Net reclassification indices were calculated to examine how well the lower ACC/AHA diagnostic threshold reclassifies outcomes of pregnancy compared with the current ACOG definition of hypertension. RESULTS Applying the ACC/AHA criteria to 137 389 pregnancies of women (mean [SD] age at time of delivery, 30.1 [5.8] years) resulted in a 14.3% prevalence of chronic hypertension (19 621 pregnancies) and a 13.8% prevalence of gestational hypertension (18 998 pregnancies). A 17.8% absolute increase was found in the overall prevalence of hypertension from 10.3% to 28.1%. The 2.1% of women who were reclassified with chronic rather than gestational hypertension had the highest risk of developing preeclampsia compared with women without hypertension by either criterion (adjusted risk ratio, 13.58; 95% CI, 12.49-14.77). Overall, the use of the ACC/AHA criteria to diagnose hypertension resulted in a 20.8% improvement in the appropriate identification of future preeclampsia, but only a 3.8% improvement of appropriate fetal/neonatal risk classification. CONCLUSIONS AND RELEVANCE Using the lower diagnostic threshold for hypertension recommended in the 2017 ACC/AHA guideline increased the prevalence of chronic and gestational hypertension, markedly improved the appropriate identification of women who would go on to develop preeclampsia, and was associated with the identification of adverse fetal/neonatal risk.

J Clin Hypertens (Greenwich) 2021; 23:1060-1067. [PMID: 33400389 PMCID: PMC8678830 DOI: 10.1111/jch.14149] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2020] [Revised: 12/10/2020] [Accepted: 12/12/2020] [Indexed: 01/16/2023]
Abstract
Studies reported that women in a low‐risk cohort with stage 1 hypertension defined as 130–139 mmHg/80–89 mmHg, according to the American College of Cardiology/American Heart Association, are more likely to develop into preeclampsia than women with normotensive in the early gestation. In this study, the authors investigated whether preeclampsia was more likely to occur in stage 1 hypertensive women compared to the normotensive pregnant women in a high‐risk cohort, which was based on the randomized controlled trial of "Low‐dose Aspirin in the Prevention of Preeclampsia in China." Meanwhile, the authors further evaluated the preventive effect of aspirin for preeclampsia in stage 1 hypertension subset. In women enrolled at or before 16 weeks of gestation, in the control group, the preeclampsia occurrence was significantly higher in stage 1 hypertensive woman than in the normotensive women (20.4% vs. 6.2%, aOR 3.960, 95% CI 1.299–12.074, p = .016), while no difference was observed in the aspirin group (4.5% vs. 4.2%, aOR 0.921, 95% CI 0.140–6.070, p = .932). In stage 1 hypertension, the incidences of preeclampsia and preterm birth were significantly lower in the aspirin group as compared to the control group (4.5% vs. 20.4%, aOR 0.139, 95% CI 0.027–0.716, p = .018; 4.5% vs. 18.4%, aOR 0.141, 95% CI 0.025–0.782, p = .025). Compared with the control group, the aspirin group displayed significantly prolonged gestational age at delivery (38.6 ± 1.2 vs. 37.4 ± 3.4, p = .042). This study indicates that the newly classified stage 1 hypertension might be an additional risk factor for preeclampsia in Chinese high‐risk pregnant women, and aspirin intervention might be useful.

Abstract
BACKGROUND Rates of maternal mortality are increasing in the United States with significant rural-urban disparities. Pre-pregnancy hypertension is a well-established risk factor for adverse maternal and offspring outcomes. OBJECTIVES The purpose of this study was to describe trends in maternal pre-pregnancy hypertension among women in rural and urban areas in 2007 to 2018 in order to inform community-engaged prevention and policy strategies. METHODS We performed a nationwide, serial cross-sectional study using maternal data from all live births in women age 15 to 44 years between 2007 and 2018 (CDC Natality Database). Rates of pre-pregnancy hypertension were calculated per 1,000 live births overall and by urbanization status. Subgroup analysis in standard 5-year age categories was performed. We quantified average annual percentage change using Joinpoint Regression and rate ratios (95% confidence intervals [CIs]) to compare yearly rates between rural and urban areas. RESULTS Among 47,949,381 live births to women between 2007 and 2018, rates of pre-pregnancy hypertension per 1,000 live births increased among both rural (13.7 to 23.7) and urban women (10.5 to 20.0). Two significant inflection points were identified in 2010 and 2016, with highest annual percentage changes between 2016 and 2018 in rural and urban areas. Although absolute rates were lower in younger compared with older women in both rural and urban areas, all age groups experienced similar increases. The rate ratios of pre-pregnancy hypertension in rural compared with urban women ranged from 1.18 (95% CI: 1.04 to 1.35) for ages 15 to 19 years to 1.51 (95% CI: 1.39 to 1.64) for ages 40 to 44 years in 2018. CONCLUSIONS Maternal burden of pre-pregnancy hypertension has nearly doubled in the past decade and the rural-urban gap has persisted.

Abstract
OBJECTIVE To investigate whether women with early pregnancy elevated blood pressure (BP) or stage 1 hypertension exhibit increased risk of preeclampsia and maternal or neonatal morbidity. METHODS We conducted a clinical cohort study of 18,162 women who delivered a singleton neonate from 2015 to 2018 and attended at least two prenatal appointments before 20 weeks of gestation. Data were collected within the Magee Obstetric Maternal and Infant database, an aggregate of prenatal and delivery health records. Early pregnancy BP was defined as average BP before 20 weeks of gestation, and women were classified with normal, elevated BP, stage 1 or 2 hypertension according to current guidelines. The primary outcome was preeclampsia. Secondary outcomes were severe maternal morbidity, placental abruption, gestational diabetes, and composite neonatal morbidity. RESULTS Overall, 75.2% of the women were categorized with normal BP, 13.9% with elevated BP, 5.4% with stage 1 hypertension, and 5.5% with stage 2 hypertension. Risk of preeclampsia increased in a stepwise fashion with increasing BP category, adjusted for covariates (normal BP, 4.7%, referent; elevated BP, 7.3%, adjusted odds ratio [aOR] 1.29, 95% CI 1.07-1.56; stage 1, 12.3%, aOR 2.35, 95% CI 1.86-2.96), and stage 2, 30.2%, aOR 6.49, 95% CI 5.34-7.89). Results were similar among black and white women. Gestational diabetes was more prevalent among women with stage 1 (11.4%; aOR 1.50, 95% CI 1.18-1.91] and stage 2 hypertension (14.2%; aOR 1.65, 95% CI 1.30-2.10). Severe maternal morbidity and neonatal morbidity were increased only among women with stage 2 hypertension (aOR 2.99, 95% CI 2.26-3.99, and aOR 2.67, 95% CI 2.28-3.12, respectively). CONCLUSION Women with elevated BP, and stage 1 and 2 hypertension in early pregnancy are at increased risk for preeclampsia. These findings emphasize the importance of applying the 2017 BP guidelines to reproductive-aged women. Strategies to incorporate these guidelines into obstetric care may also be warranted.

Abstract
BACKGROUND Due to the significance of preeclampsia (PE) and its adverse outcomes in the health of both mother and newborn, the present study was carried out to investigate the effect of aspirin on preventing the occurrence of PE, intrauterine growth restriction (IUGR), and preterm delivery in women with a previous history of PE. METHODS The present clinical trial was conducted on 90 pregnant women with a previous history of PE referred to the Khalij Fars Hospital in Bandar Abbas, Hormozgan Province Iran from April 2017 to August 2018. The subjects of the study were randomly assigned into two groups of intervention and control to receive either 80 mg of aspirin or placebo daily during the pregnancy. Patients' information was obtained and recorded upon entering the study, follow-up visits, and childbirth. RESULTS Among participants who entered the clinical trial, 86 patients (95.6%) completed the study. During the pregnancy, systolic blood pressure increased by 8.25 ± 14.83 and 19.06 ± 18.33 mmHg in aspirin and placebo groups, respectively (p = 0.001). Also, the same happened with diastolic blood pressure (6.12 ± 11.46 vs 13.48 ± 13.95 mmHg, p = 0.010). The rate of PE was equal to 27 (62.8%) and 38 (88.4%) in the aspirin and placebo groups, respectively (aOR = 0.23, p = 0.013). In the aspirin group, the rate of IUGR was equal to 27.9% compared with 25.6% of newborns in the control group (aOR = 1.18, p = 0.750). Similarly, there was no significant difference in the rate of preterm delivery between the two groups (p = 0.061). CONCLUSION The findings of the present study conducted exclusively on women with previous documented PE revealed that taking aspirin may have a preventive effect on PE in the current pregnancy.

Abstract
PURPOSE OF REVIEW Hypertensive disorders of pregnancy affect about 5-10% of pregnancies impacting maternal, fetal, and neonatal outcomes. We review the recent studies in this field and discuss the pathophysiology, diagnosis, and management of hypertension during pregnancy, as well as the short- and long-term consequences on the cardiovascular health of women. RECENT FINDINGS Although the American College of Cardiology/American Heart Association revised their guidelines for hypertension in the general population in 2017, hypertension during pregnancy continues to be defined as a systolic blood pressure (SBP) ≥ 140 mmHg and/or a diastolic blood pressure (DBP) ≥ 90 mmHg, measured on two separate occasions. The addition of stage 1 hypertension will increase the prevalence of hypertension during pregnancy, identifying more women at risk of preeclampsia; however, more research is needed before changing the BP goal because a lower target BP has a risk of poor placental perfusion. Women with chronic hypertension have a higher incidence of superimposed preeclampsia, cesarean section, preterm delivery before 37 weeks' gestation, birth weight less than 2500 g, neonatal unit admission, and perinatal death. They also have a higher risk of developing cardiovascular disease later in life. The guidelines recommend low-dose aspirin for women with moderate and high risk of preeclampsia. While treating pregnant women with hypertension, the effectiveness of the antihypertensive agent must be balanced with risks to the fetus. Hypertensive disorders of pregnancy should be appropriately and promptly recognized and treated during pregnancy. They should further be co-managed by the obstetrician and cardiologist to decrease the long-term negative impact on the cardiovascular health of women.

Abstract
Preeclampsia is a severe pregnancy complication with high potential for adverse effects on maternal and fetal health during the perinatal period. It is also associated with an increased risk of maternal cardiovascular disease later in life. Development of preeclampsia can be decreased by prescribing low-dose aspirin to high-risk women. At present, maternal and pregnancy factors are used to assess the risk of preeclampsia. One additional factor that could add to the assessment of risk is a family history of hypertension, cardiovascular disease, or diabetes, especially for nulliparous women who do not have a pregnancy history to inform treatment decisions. Therefore, we conducted a systematic review to assess the association between family history of the aforementioned conditions and preeclampsia. Four databases including MEDLINE, EMBASE, the Cochrane Library, and CINAHL/pre-CINAHL were searched for observational studies that examined a family history of hypertension, cardiovascular disease, or diabetes in women with preeclampsia and in a control population. Studies were evaluated for quality using the Newcastle-Ottawa Scale. A total of 84 relevant studies were identified. A meta-analysis was not conducted due to suspected heterogeneity in the included studies. Most studies reported a positive association between a family history of hypertension or cardiovascular disease and the development of preeclampsia. The majority of studies examining family history of diabetes reported non-significant associations. Overall, family history of hypertension or cardiovascular disease is associated with a higher risk for developing preeclampsia and should be considered when assessing women in the first trimester for low-dose aspirin.

Abstract
After a child is born, the examination of the placenta by a pathologist for abnormalities, such as infection or maternal vascular malperfusion, can provide important information about the immediate and long-term health of the infant. Detection of the pathologic placental blood vessel lesion decidual vasculopathy (DV) has been shown to predict adverse pregnancy outcomes, such as preeclampsia, which can lead to mother and neonatal morbidity in subsequent pregnancies. However, because of the high volume of deliveries at large hospitals and limited resources, currently a large proportion of delivered placentas are discarded without inspection. Furthermore, the correct diagnosis of DV often requires the expertise of an experienced perinatal pathologist. We introduce a hierarchical machine learning approach for the automated detection and classification of DV lesions in digitized placenta slides, along with a method of coupling learned image features with patient metadata to predict the presence of DV. Ultimately, the approach will allow many more placentas to be screened in a more standardized manner, providing feedback about which cases would benefit most from more in-depth pathologic inspection. Such computer-assisted examination of human placentas will enable real-time adjustment to infant and maternal care and possible chemoprevention (eg, aspirin therapy) to prevent preeclampsia, a disease that affects 2% to 8% of pregnancies worldwide, in women identified to be at risk with future pregnancies.

Abstract
Chronic hypertension affects 1-5% of women of childbearing age. During pregnancy, chronic hypertension is associated with an increased risk of vascular disease such as superimposed preeclampsia (PE), intrauterine growth retardation (IUGR), placental abruption, and preterm delivery. These serious and frequent pathologies, specific to pregnancy, carry a particularly high risk of maternal complications (HELLP syndrome, eclampsia, maternal death) and perinatal complications (perinatal death, neurological disorders). To date, there is no curative treatment of vascular complications of chronic hypertension during pregnancy. The only effective treatment, once the complications are established, is usually stopping the pregnancy and delivering the placenta. Some recommendations suggest the use of low dose aspirin in the prevention of these complications. Although the efficacy of low-dose aspirin is assumed in patients with previous preeclampsia, few studies have evaluated its efficacy in patients with chronic hypertension. Controlled prospective studies using very low doses of aspirin (less than 100 mg) and started after 15 weeks of gestation do not seem conclusive. The objective of this work is first to detail the complications of chronic hypertension during pregnancy, then to analyze the studies which evaluated the interest of low dose aspirin in prevention of the placental vascular complications of the pregnancy in patients with chronic hypertension. We also propose an update on the European and North American national recommendations for the prevention of preeclampsia by low dose aspirin in the high-risk population of patients with chronic hypertension. Finally we present the CHASAP (Chronic Hypertension and Acetyl Salicylic Acid in Pregnancy) trial (NCT04356326), a multicentric prospective randomized double-blind superiority trial, which will compare, in pregnant women with chronic hypertension, the efficacy of low dose aspirin (150 mg/day) with a placebo, in the prevention of maternal-fetal morbidity and mortality (preeclampsia, placental abruption, IUGR, perinatal death, maternal death, and preterm delivery).

Abstract
The recommendations for the diagnosis of stage 1 hypertension were recently revised by the American Heart Association primarily based on its impact on cardiovascular disease risks. Whether the newly diagnosed stage 1 hypertension impacts pregnancy complications remain poorly defined. We designed a retrospective cohort study to investigate the associations of stage 1 hypertension detected in early gestation (<20 weeks) with risks of adverse pregnancy outcomes stratified by prepregnancy body mass index. A total of 47 874 women with singleton live births and blood pressure (BP) <140/90 mm Hg were included, with 5781 identified as stage 1a (systolic BP, 130-134 mm Hg; diastolic BP, 80-84 mm Hg; or both) and 3267 as stage 1b hypertension (systolic BP, 135-139 mm Hg; diastolic BP, 85-90 mm Hg; or both). Slightly higher, yet significant, rates and risks of gestational diabetes mellitus, preterm delivery, and low birth weight (<2500 g) were observed in both groups compared with normotensive controls. Importantly, women with stage 1a and stage 1b hypertension had significantly increased incidences of hypertensive disorders in pregnancy compared with normotensive women (adjusted odds ratio, 2.34 [95% CI, 2.16-2.53]; 3.05 [2.78-3.34], respectively). After stratifying by body mass index, stage 1a and 1b hypertension were associated with increased hypertensive disorders in pregnancy risks in both normal weight (body mass index, 18.5-24.9; adjusted odds ratio, 2.44 [2.23-2.67]; 3.26 [2.93-3.63]) and the overweight/obese (body mass index, ≥25; adjusted odds ratio, 1.90 [1.56-2.31]; 2.36 [1.92-2.90]). Current findings suggested significantly increased adverse pregnancy outcomes associated with stage 1 hypertension based on the revised American Heart Association guidelines, especially in women with prepregnancy normal weight.

Abstract
Objective: To compare the rate of adverse pregnancy outcomes of women with hypertension defined by the ACC-AHA guidelines, women with hypertension defined by ACOG guidelines, and normotensive women.Methods: A historical cohort study of women with singleton, nonanomalous pregnancies who presented before 20 weeks for their first prenatal visit between 1 January 2014 and 31 January 2016 with (a) hypertension defined by ACC-AHA (systolic blood pressure 130 mmHg and/or diastolic blood pressure of 80 mmHg documented), (b) hypertension defined by ACOG (systolic blood pressure of 140 mmHg and/or diastolic blood pressure of 90 mmHg documented) and (c) women documented to be normotensive. Primary outcomes were preeclampsia and small for gestational age. Fisher's exact test was used to compare demographics and risk factors between the groups. Multivariable logistic regression analysis was used to predict the association of preeclampsia within the groups adjusting for additional risk factors.Results: A total of 252 women were included. Of these, 92 (36.5%) had hypertension by ACC-AHA, 34 (13.5%) by ACOG and 126 (50%) were normotensive. Sixty percent of women with the ACOG definition developed preeclampsia compared to 45.1% of women with the ACC-AHA definition and 17.1% in the control group (p < .001). The rate of preeclampsia among women with hypertension by ACC-AHA criteria was not significantly different from the rate among women with hypertension by ACOG criteria (p = .288). Differences in small for gestational age among the groups were not significant (ACOG: 20%, ACC-AHA: 11.1%, normotensive: 9.8%, p = .423).Conclusion: Women with hypertension defined by ACC-AHA have a rate of developing preeclampsia that is similar to that of women with hypertension defined by ACOG.

Front Cardiovasc Med 2019; 6:160. [PMID: 31803757 PMCID: PMC6873287 DOI: 10.3389/fcvm.2019.00160] [Citation(s) in RCA: 35] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2019] [Accepted: 10/21/2019] [Indexed: 01/04/2023] Open
Abstract
Introduction: Hypertensive disorders (HDP) affect ~7% of pregnancies. Epidemiological evidence strongly suggests HDP independently increases that individual's risk of later cardiovascular disease (CVD). Focus on reduction or mitigation of this risk has been limited. This review seeks to identify trialed interventions to reduce cardiovascular risk after HDP. Methods: Online medical databases were searched to identify full-text published results of randomized controlled trials (RCT) in women <10 years postpartum after HDP that trialed interventions to reduce cardiovascular risk. Outcomes sought included cardiovascular disease events, chronic hypertension, and other measures of cardiovascular risk such as obesity, smoking status, diet, and physical activity. Publications from January 2008 to July 2019 were included. Results: Two RCTs were identified. One, a trial of calcium vs. placebo in 201 women with calcium commenced from the first follow-up visit outside of pregnancy and continued until 20 weeks' gestation if another pregnancy occurred. A non-significant trend toward decreased blood pressure was noted. The second RCT of 151 women tested an online education programme (vs. general information to control group) to increase awareness of risk factors and personalized phone-based lifestyle coaching in women who had a preeclampsia affected pregnancy in the 5 years preceding enrolment. Significant findings included increase in knowledge of CVD risk factors, reported healthy eating and decreased physical inactivity, however adoption of a promoted heart healthy diet and physical activity levels did not differ significantly between groups. Several observational studies after HDP, and one meta-analysis of studies of lifestyle interventions not performed specifically after HDP but used to extrapolate likely benefits of lifestyle interventions, were identified which supported the use of lifestyle interventions. Several ongoing RCTs were also noted. Discussion: There is a paucity of intervention trials in the early years after HDP to guide evidence-based cardiovascular risk reduction in affected women. Limited evidence suggests lifestyle intervention may be effective, however degree of any risk reduction remains uncertain. Conclusion: Sufficiently powered randomized controlled trials of appropriate interventions (e.g., lifestyle behavior change, pharmacological) are required to assess the best method of reducing the risk of cardiovascular disease in this at-risk population of women.

Blood pressure trajectory and category and risk of hypertensive disorders of pregnancy in nulliparous women. Am J Obstet Gynecol 2019; 221:277.e1-277.e8. [PMID: 31255629 PMCID: PMC6732036 DOI: 10.1016/j.ajog.2019.06.031] [Citation(s) in RCA: 59] [Impact Index Per Article: 11.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2019] [Revised: 06/10/2019] [Accepted: 06/12/2019] [Indexed: 01/17/2023]
Abstract
BACKGROUND Recently updated American College of Cardiology/ American Heart Association (ACC/AHA) guidelines redefine blood pressure categories as stage 1 hypertension (systolic, 130-139 mm Hg or diastolic, 80-89 mm Hg), elevated (systolic, 120-129 mm Hg and diastolic, <80 mm Hg), and normal (<120/<80 mm Hg), but their relevance to an obstetric population is uncertain. OBJECTIVE We sought to evaluate the risk of gestational hypertension or preeclampsia based on early pregnancy blood pressure category and trajectory. STUDY DESIGN We utilized data from the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be cohort, a prospective observational study of nulliparous women with singleton pregnancies conducted at 8 clinical sites between 2010 and 2014. Women included in this analysis had no known history of prepregnancy hypertension (blood pressure, ≥140/90 mm Hg) or diabetes. We compared the frequency of hypertensive disorders of pregnancy, including preeclampsia and gestational hypertension, among women based on ACC/AHA blood pressure category at a first-trimester study visit and blood pressure trajectory between study visits in the first and second trimesters. Blood pressure trajectories were categorized based on blood pressure difference between visits 1 and 2 as stable (<5 mm Hg difference), upward (≥5 mm Hg), or downward (≤-5 mm Hg). Associations of blood pressure category and trajectory with preeclampsia and gestational hypertension were assessed via univariate analysis and multinomial logistic regression analysis with covariates identified a priori. RESULTS A total of 8899 women were included in the analysis. Study visit 1 occurred at a mean gestational age of 11.6 ± 1.5 weeks and study visit 2 at a mean gestational age of 19.0 ± 1.6 weeks. First-trimester blood pressure category was significantly associated with both preeclampsia and gestational hypertension, with increasing blood pressure category associated with a higher risk of all hypertensive disorders of pregnancy. Elevated blood pressure was associated with an adjusted relative risk of 1.54 (95% confidence interval, 1.18-2.02) and stage 1 hypertension was associated with adjusted relative risk of 2.16 (95% confidence interval, 1.31-3.57) of any hypertensive disorder of pregnancy. Stage 1 hypertension was associated with the highest risk of preeclampsia with severe features, with an adjusted relative risk of 2.48 (95% confidence interval, 1.38-8.74). Both systolic and diastolic blood pressure trajectories were also significantly associated with the risk of hypertensive disorders of pregnancy independent of blood pressure category (P < .001). Women with a blood pressure categorized as normal and with an upward systolic trajectory had a 41% increased risk of any hypertensive disorder of pregnancy (adjusted relative risk, 1.41; 95% confidence interval, 1.20-1.65) compared to women with a downward systolic trajectory. CONCLUSION In nulliparous women, blood pressure category and trajectory in early pregnancy are independently associated with risk of preeclampsia and gestational hypertension. Our study demonstrates that blood pressure categories with lower thresholds than those traditionally used to identify individuals as hypertensive may identify more women at risk for preeclampsia and gestational hypertension.

Elevated diastolic blood pressure until mid-gestation is associated with preeclampsia and small-for-gestational-age birth: a population-based register study. BMC Pregnancy Childbirth 2019; 19:186. [PMID: 31138157 PMCID: PMC6537437 DOI: 10.1186/s12884-019-2319-2] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2018] [Accepted: 04/25/2019] [Indexed: 01/08/2023] Open
Abstract
BACKGROUND Gestational hemodynamic adaptations, including lowered blood pressure (BP) until mid-gestation, might benefit placental function. We hypothesized that elevated BP from early to mid-gestation increases risks of preeclampsia and small-for-gestational-age birth (SGA), especially in women who also deliver preterm (< 37 weeks). METHODS In 64,490 healthy primiparous women, the change in systolic and diastolic BP from early to mid-gestation was categorized into lowered (≥ 0 mmHg decreased), and elevated (≥ 1 mmHg increase). Women with chronic hypertension, chronic renal disease, pre-gestational diabetes and systemic lupus erythematosus were excluded. Risks of preeclampsia and SGA birth were estimated by logistic regression, presented with adjusted odds ratio (aOR) and 95% confidence intervals (CI). Further, the effect of BP change in combination with stage 1 hypertension (systolic BP 130-139 mmHg or diastolic BP 80-89 mmHg) in early gestation was estimated. RESULTS Compared to women with lowered diastolic BP from early to mid-gestation, those with elevated diastolic BP had increased risks of preeclampsia (aOR: 1.8 [1.6-2.0]) and SGA birth (aOR: 1.3 [1.2-1.5]). The risk estimates were higher for preeclampsia and SGA when combined with preterm birth (aORs: 2.2 [1.8-2.8] and 2.3 [1.8-3.0], respectively). The highest rate of preeclampsia (9.9%) was seen in women with stage 1 hypertension in early gestation and a diastolic BP that was elevated until mid-gestation. This was three times the risk, compared to women with normal BP in early gestation and a diastolic BP that was decreased until mid-gestation. The association between elevated systolic BP from early to mid-gestation and preeclampsia was weak, and no significant association was found between changes in systolic BP and SGA births. CONCLUSION Elevated diastolic BP from early to mid-gestation was associated with increased risks of preeclampsia and SGA, especially for women also delivering preterm. The results may imply that the diastolic BP starts to increase around mid-gestation in women later developing placental dysfunction disorders.
