ABSTRACT

Hypertensive disorders of pregnancy (HDP) are among the major causes of high maternal and fetal/neonatal morbidity and mortality rates. Patients with HDP have significantly elevated N-terminal pro-brain natriuretic peptide (NT-proBNP) levels at diagnosis; however, the NT-proBNP levels during early pregnancy are largely unknown. This study aimed to validate the association between HDP and NT-proBNP levels. This retrospective study evaluated 103 pregnant women who developed HDP diagnosed after 35 weeks of gestation and 667 who did not. The HDP group had significantly lower early-pregnancy NT-proBNP levels than the without HDP group. However, the two groups did not significantly differ in terms of the late-pregnancy NT-proBNP levels. After adjusting for confounding factors such as age, body mass index, parity, and blood pressure levels, high early-pregnancy NT-proBNP levels were associated with a lower HDP risk. Early-pregnancy NT-proBNP levels ≥ 60.5 pg/mL had a negative predictive value of 97.0% for ruling out HDP, with a sensitivity of 87.4% and specificity of 62.5%. In conclusion, elevated early-pregnancy NT-proBNP levels were associated with a lower HDP risk. Moreover, a cutoff point of ≥ 60.5 pg/mL for early-pregnancy NT-proBNP levels had a high negative predictive value and sensitivity for ruling out HDP. These findings can provide new clinical implications.

ABSTRACT

BACKGROUND: Hypertensive disorders of pregnancy (HDP) are associated with subsequent adverse cardiac remodeling and cardiovascular disease. The role of myocardial microvascular disease among individuals with HDP and left ventricular (LV) remodeling as a potential link to cardiovascular disease is unknown. We aimed to determine whether individuals with HDP history have coronary microvascular dysfunction measured by coronary flow reserve 8 to 10 years after delivery and whether microvascular dysfunction correlates with LV remodeling. METHODS: Individuals with pregnancies delivered from 2008 to 2010 underwent burst-replenishment myocardial contrast echocardiography (2017-2020) to quantify myocardial perfusion at rest and during dobutamine stress. Video intensity versus time data were used to derive ß, the rate of rise of video intensity, a correlate for myocardial blood flow. Coronary flow reserve was calculated as the ratio of ß at peak stress to ß at rest, averaged across LV myocardial regions of interest. RESULTS: We studied 91 individuals (aged 38±6 and 9.1±0.9 years postdelivery) and 19 with a history of HDP. Individuals with coronary microvascular dysfunction (coronary flow reserve <2.0; n=13) had a higher proportion of HDP (46.2% versus 16.7%; P=0.026) and higher prepregnancy body mass index, baseline heart rate, and hemoglobin A1c compared with those without microvascular dysfunction. The association of coronary flow reserve and HDP was attenuated after adjusting for cardiometabolic factors (P=0.133). In exploratory subgroup analyses, individuals with both LV remodeling (relative wall thickness >0.42) and HDP (n=12) had the highest proportion of microvascular dysfunction (41.7% versus +HDP-LV remodeling [n=7] 14.3%; -HDP+LV remodeling [n=26] 7.7%; P=0.0498). CONCLUSIONS: In this small study, HDP history is associated with coronary microvascular dysfunction 1 decade after delivery, findings that may, in part, be driven by metabolic factors including obesity and diabetes. Microvascular dysfunction may contribute to cardiovascular disease among individuals with a history of HDP.

ABSTRACT

Cardiovascular disease is the leading cause of maternal death among Black women in the United States. A large, urban hospital adopted remote patient blood pressure monitoring (RBPM) to increase blood pressure monitoring and improve the management of hypertensive disorders of pregnancy (HDP) by reducing the time to diagnosis of HDP. The digital platform integrates with the electronic health record (EHR), automatically inputting RBPM readings to the patients' chart; communicating elevated blood pressure values to the healthcare team; and offers a partial offset of the cost through insurance plans. It also allows for customization of the blood pressure values that prompt follow-up to the patient's risk category. This paper describes a protocol for evaluating its impact. Objective 1 is to measure the effect of the digitally supported RBPM on the time to diagnosis of HDP. Objective 2 is to test the effect of cultural tailoring to Black participants. The ability to tailor digital content provides the opportunity to test the added value of promoting social identification with the intervention, which may help achieve equity in severe maternal morbidity events related to HDP. Evaluation of this intervention will contribute to the growing literature on digital health interventions to improve maternity care in the United States.

ABSTRACT

BACKGROUND: Despite major advances in the pharmacologic treatment of hypertension in the nonpregnant population, treatments for hypertension in pregnancy have remained largely unchanged over the years. There is recent evidence that a more adequate control of maternal blood pressure is achieved when the first given antihypertensive drug is able to correct the underlying hemodynamic disorder of the mother besides normalizing the blood pressure values. OBJECTIVE: This study aimed to compare the blood pressure control in women receiving an appropriate or inappropriate antihypertensive therapy following the baseline hemodynamic findings. STUDY DESIGN: This was a prospective multicenter study that included a population of women with de novo diagnosis of hypertensive disorders of pregnancy. A noninvasive assessment of the following maternal parameters was performed on hospital admission via Ultrasound Cardiac Output Monitor before any antihypertensive therapy was given: cardiac output, heart rate, systemic vascular resistance, and stroke volume. The clinician who prescribed the antihypertensive therapy was blinded to the hemodynamic evaluation and used as first-line treatment a vasodilator (nifedipine or alpha methyldopa) or a beta-blocker (labetalol) based on his preferences or on the local protocols. The first-line pharmacologic treatment was retrospectively considered hemodynamically appropriate in either of the following circumstances: (1) women with a hypodynamic profile (defined as low cardiac output [≤5 L/min] and/or high systemic vascular resistance [≥1300 dynes/second/cm2]) who were administered oral nifedipine or alpha methyldopa and (2) women with a hyperdynamic profile (defined as normal or high cardiac output [>5 L/min] and/or low systemic vascular resistances [<1300 dynes/second/cm2]) who were administered oral labetalol. The primary outcome of the study was to compare the occurrence of severe hypertension between women treated with a hemodynamically appropriate therapy and women treated with an inappropriate therapy. RESULTS: A total of 152 women with hypertensive disorders of pregnancy were included in the final analysis. Most women displayed a hypodynamic profile (114 [75.0%]) and received a hemodynamically appropriate treatment (116 [76.3%]). The occurrence of severe hypertension before delivery was significantly lower in the group receiving an appropriate therapy than in the group receiving an inappropriately treated (6.0% vs 19.4%, respectively; P=.02). Moreover, the number of women who achieved target values of blood pressure within 48 to 72 hours from the treatment start was higher in the group who received an appropriate treatment than in the group who received an inappropriate treatment (70.7% vs 50.0%, respectively; P=.02). CONCLUSION: In pregnant individuals with de novo hypertensive disorders of pregnancy, a lower occurrence of severe hypertension was observed when the first-line antihypertensive agent was tailored to the correct maternal hemodynamic profile.

ABSTRACT

N-terminal prohormone of brain natriuretic peptide (NT-proBNP) is a non-active prohormone secreted by ventricular cardiomyocytes into the circulation in response to ventricle overload, mainly due to increased blood volume. The changes in NT-proBNP levels during pregnancy have been investigated in multiple studies. In the case of hypertensive disorders of pregnancy, increased vasoconstriction leads to increased blood pressure and afterload. Together with the volume overload of pregnancy, it leads to higher NT-proBNP secretion. As hypertensive disorders of pregnancy are among the leading causes of prematurity and perinatal mortality, early prediction and diagnosis of gestational hypertension, and preeclampsia are essential for improving maternal and infant prognosis. NT-proBNP has been regarded as a potential biomarker of hypertensive disorders of pregnancy. In this review, we have thoroughly summarized the current data on the prognostic and diagnostic utility of NT-proBNP in patients with gestational hypertension and preeclampsia. NT-proBNP values may help distinguish between non-preeclamptic and preeclamptic patients, even if there are no significant differences in blood pressure. Moreover, in pregnancies complicated by preeclampsia, the value of increased NT-proBNP level is related to the stage and the severity of the disease. Further improvement of our knowledge about NT-proBNP as a diagnostic biomarker and a putative predictor of adverse cardiac events in women with hypertensive disorders of pregnancy should lead to better management of these patients.

ABSTRACT

BACKGROUND: We aimed to evaluate the impact of hypertensive disorders of pregnancy occurrence, recurrence, onset time, and severity on mortality and on a wide range of cardiovascular outcomes in France. METHODS AND RESULTS: CONCEPTION (Cohort of Cardiovascular Diseases in Pregnancy) is a French nationwide prospective cohort using data from the National Health Data System. We included all women in CONCEPTION with no history of a cardiovascular event who delivered in France for the first time between 2010 and 2018 (N=2 819 655). Hypertensive disorders of pregnancy and cardiovascular outcomes during the study follow-up were identified using algorithms combining International Classification of Diseases, Tenth Revision (ICD-10) coded diagnoses during hospitalization and purchases of medication between 2010 and 2021. We fitted Cox models with time-varying exposure to assess the associations of hypertensive disorders of pregnancy with mortality and cardiovascular events. Women with gestational hypertension had a 1.25- to 2-fold higher risk of stroke, acute coronary syndrome, peripheral arterial disease, pulmonary embolism, and chronic kidney disease, and a 2- to 4-fold higher risk of rhythm and conduction disorder and heart failure. Women with preeclampsia had a 1.35- to 2-fold higher risk of rhythm or conduction disorder and pulmonary embolism during follow-up; a 2- to 4-fold higher risk of stroke, acute coronary syndrome, and peripheral arterial disease; and a 7- to 9-fold higher risk of heart failure and chronic kidney disease. They were 1.8 times more likely to die and 4.4 times more likely to die of cardiovascular causes. CONCLUSIONS: Hypertensive disorders of pregnancy drastically increase the risk of mortality, cardiovascular, and renal events early after pregnancy. Recurrent, severe, and early-onset preeclampsia further increases this risk.

ABSTRACT

Hypertensive disorders of pregnancy are a major contributor to maternal morbidity and mortality in the United States and include chronic and gestational hypertension, preeclampsia, HELLP (hemolysis, elevated liver enzymes, and low platelet count) syndrome, eclampsia, and chronic hypertension with superimposed preeclampsia. For patients with chronic hypertension, oral antihypertensive therapy should be initiated or titrated at a blood pressure threshold of 140/90 mm Hg or greater. Gestational hypertension and preeclampsia without severe features can be managed with blood pressure monitoring, laboratory testing for disease progression, antenatal testing for fetal well-being, and delivery at 37 weeks' gestation. The use of antihypertensive drugs to control nonsevere hypertension in the setting of gestational hypertension and preeclampsia does not improve outcomes and is not recommended. Antihypertensive therapy should be initiated expeditiously for acute-onset severe hypertension to prevent hemorrhagic stroke. Preeclampsia with severe features requires immediate stabilization and inpatient treatment with magnesium sulfate for seizure prophylaxis and antenatal corticosteroids (if preterm). Patients in the preterm period should receive antenatal corticosteroids without delaying delivery to complete courses. Hypertensive disorders of pregnancy can worsen or initially present after delivery and account for up to 44% of pregnancy-related deaths in the first six days postpartum. Patients should be monitored closely in the early postpartum period. Hypertensive disorders of pregnancy are linked to poor long-term maternal and fetal outcomes, including increased maternal lifetime risk of cardiovascular disease. Daily low-dose aspirin therapy starting at 12 to 16 weeks' gestation is safe and effective for reducing the risk of preeclampsia for patients with risk factors.

ABSTRACT

Hypertensive disorders in pregnancy (HDP) are a group of conditions-including chronic hypertension, gestational hypertension, preeclampsia with and without end-organ damage, and acute complications, which include HELLP (hemolysis, elevated liver enzymes, and low platelets) syndrome and eclampsia-that could lead to severely adverse outcomes for both mother and fetus. The incidence of HDP has increased, affecting one out of seven delivery hospitalizations. Physicians should be aware of HDP for early identification and proper treatment to improve patient outcomes.

ABSTRACT

According to the American College of Obstetricians and Gynecologists (ACOG), women who have a systolic blood pressure ≥ 140 mm Hg and/or a diastolic pressure ≥ 90 mm Hg before pregnancy or before 20 weeks of gestation have chronic hypertension. Up to 1.5% of women in their childbearing years have a diagnosis of chronic hypertension, and 16% of pregnant women develop hypertension during their pregnancy. Physiological cardiovascular changes from pregnancy may mask or exacerbate hypertensive diseases during gestation, which is why prepregnancy counseling is emphasized for all patients to optimize comorbidities and establish a patient's baseline blood pressure. This review provides an overview of the diagnoses and treatments of hypertensive diseases that can occur in pregnancy, including definitions of key terms and types of hypertension as well as ACOG recommendations.

ABSTRACT

Recently, many phenotyping algorithms for high-throughput cohort identification have been developed. Prospective genome cohort studies are critical resources for precision medicine, but there are many hurdles in the precise cohort identification. Consequently, it is important to develop phenotyping algorithms for cohort data collection. Hypertensive disorders of pregnancy (HDP) is a leading cause of maternal morbidity and mortality. In this study, we developed, applied, and validated rule-based phenotyping algorithms of HDP. Two phenotyping algorithms, algorithms 1 and 2, were developed according to American and Japanese guidelines, and applied into 22,452 pregnant women in the Birth and Three-Generation Cohort Study of the Tohoku Medical Megabank project. To precise cohort identification, we analyzed both structured data (e.g., laboratory and physiological tests) and unstructured clinical notes. The identified subtypes of HDP were validated against reference standards. Algorithms 1 and 2 identified 7.93% and 8.08% of the subjects as having HDP, respectively, along with their HDP subtypes. Our algorithms were high performing with high positive predictive values (0.96 and 0.90 for algorithms 1 and 2, respectively). Overcoming the hurdle of precise cohort identification from large-scale cohort data collection, we achieved both developed and implemented phenotyping algorithms, and precisely identified HDP patients and their subtypes from large-scale cohort data collection.

ABSTRACT

BACKGROUND: Congenital and acquired heart disease complicate 1% to 4% of pregnancies in the United States. Beyond the risks of the underlying maternal congenital heart disease, cardiac surgery and its sequelae, such as surgical scarring resulting in higher rates of arrhythmias and implanted valves altering anticoagulation status, have potential implications that could affect gestation and delivery. OBJECTIVE: This study aimed to investigate whether history of maternal cardiac surgery is associated with adverse obstetrical or neonatal outcomes compared with patients without a history of cardiac disease or surgery, considered "healthy controls." STUDY DESIGN: This is a secondary analysis of retrospective cohort studies performed at a tertiary care facility in the United States comparing obstetrical outcomes in patients with a history of open cardiac surgery who delivered from January 2007 to December 2018 with healthy controls, who delivered from April 2020 to July 2020. There were 74 pregnancies in 61 patients with a history of open cardiac surgery that were compared with pregnancies in healthy controls. Of the 74 pregnancies, 65 were successfully matched based on gestational age to controls at a 1:3 (case-to-control) ratio. The remainder of cases were matched at a 1:2 or 1:1 ratio; therefore, a total of 219 control pregnancies were included in the analysis. Our primary outcome was the incidence of hypertensive disorders of pregnancy, as well as cesarean delivery, in patients with a history of open cardiac surgery compared with healthy controls. Our secondary outcome was the incidence of low-birthweight neonates in patients with a history of open cardiac surgery compared with healthy controls. RESULTS: Patients with a history of cardiac surgery were not more likely to have any hypertensive disorder diagnosed than healthy controls. Patients with a history of cardiac surgery were more likely to have an operative delivery (P<.0001) but equally likely to have a cesarean delivery (P=.528) compared with healthy controls. Birthweight was not statistically different of 2655±808 g in neonates born to patients with a history of cardiac surgery vs 2844±830 g born to healthy controls (P=.092). CONCLUSION: Patients with a history of cardiac surgery may not be at higher risk of hypertensive disorder diagnosis during pregnancy. Similarly, most patients with a history of cardiac surgery are also likely not at higher risk of cesarean delivery or low-birthweight neonates.

ABSTRACT

BACKGROUND: Hypertensive disorders of pregnancy are a leading cause of perinatal morbidity, and timely treatment of severely elevated blood pressure is recommended to prevent serious sequelae. In acute hypertension marked by increased blood volume, it is unknown whether diuretics used as an adjunct to antihypertensive medications lead to more effective blood pressure control. OBJECTIVE: This study aimed to evaluate whether the addition of intravenous furosemide to first-line antihypertensive agents reduces systolic blood pressure in acute-onset, severe antenatal hypertension with wide (≥60 mm Hg) pulse pressure. STUDY DESIGN: In this double-blinded randomized trial, participants received 40 mg of intravenous furosemide or placebo in addition to a first-line antihypertensive agent. The primary outcome was mean systolic blood pressure during the first hour after intervention. Secondary outcomes included corresponding diastolic blood pressure; systolic blood pressure, diastolic blood pressure, and pulse pressure at 2 hours after intervention; total reduction from qualifying blood pressure; duration of blood pressure control; need for additional antihypertensive doses within 1 hour; and electrolytes and urine output. A sample size of 35 participants per group was planned to detect a 15-mm Hg difference in blood pressure. RESULTS: Between January 2021 and March 2022, 65 individuals were randomized: 33 to furosemide and 32 to placebo. Baseline characteristics were similar between the groups. There was no difference in the primary outcome of mean 1-hour systolic blood pressure (147 [14.8] vs 152 [13.8] mm Hg; P=.200). We found a reduction in 2-hour systolic blood pressure (139 [18.5] vs 154 [18.4] mm Hg; P=.007) and a decrease in 2-hour pulse pressure (55 [12.5] vs 67 [15.1]; P=.003) in the furosemide group. Subgroup analysis according to hypertension type showed a significant reduction in 2-hour systolic blood pressure and 2-hour pulse pressure among patients with new-onset hypertension, but not among those with preexisting hypertension. Urine output was greater in the furosemide group, with no difference in electrolytes and creatinine before and after intervention. CONCLUSION: Intravenous furosemide in conjunction with a first-line antihypertensive agent did not significantly reduce systolic blood pressure in the first hour after administration. However, both systolic blood pressure and pulse pressure at 2 hours were decreased in the furosemide group. These findings suggest that a 1-time dose of intravenous furosemide is a reasonable adjunct to achieve blood pressure control, particularly in patients in whom increased volume is suspected.

ABSTRACT

Hypertensive disorders in pregnancy (HDP) remain a leading cause of pregnancy-related maternal and foetal morbidity and mortality worldwide, including chronic hypertension, gestational hypertension, and pre-eclampsia. Affected women and newborns also have an increased risk of cardiovascular disease later in life, independent of traditional cardiovascular disease risks. Despite these risks, recommendations for optimal diagnosis and treatment have changed little in recent decades, probably due to fear of the foetal repercussions of decreased blood pressure and possible drug toxicity. In this document we review the diagnostic criteria and classification of (HDP), as well as important aspects regarding pathophysiology and early detection that allows early identification of women at risk, with the aim of preventing both immediate and long-term consequences. Prophylactic treatment with aspirin is also reviewed early and a therapeutic approach is carried out that involves close maternal and foetal monitoring, and if necessary, the use of safe drugs in each situation. This review aims to provide an updated vision for the prevention, diagnosis, and treatment of HDP that is useful in our usual clinical practice.

ABSTRACT

BACKGROUND: Long-term (visit-to-visit) blood pressure variability (BPV) and heart rate variability (HRV) outside pregnancy are associated with adverse cardiovascular outcomes. Given the limitations of relying solely on blood pressure level to identify pregnancies at risk, long-term (visit-to-visit) BPV or HRV may provide additional diagnostic/prognostic counsel. To address this, we conducted a systematic review to examine the association between long-term BPV and HRV in pregnancy and adverse maternal and perinatal outcomes. METHODS AND RESULTS: Databases were searched from inception to May 2023 for studies including pregnant women, with sufficient blood pressure or heart rate measurements to calculate any chosen measure of BPV or HRV. Studies were excluded that reported short-term, not long-term, variability. Adjusted odds ratios were extracted. Eight studies (138 949 pregnancies) reporting BPV met our inclusion criteria; no study reported HRV and its association with pregnancy outcomes. BPV appeared to be higher in women with hypertension and preeclampsia specifically, compared with unselected pregnancy cohorts. Greater BPV was associated with significantly more adverse pregnancy outcomes, particularly maternal (gestational hypertension [odds ratio range, 1.40-2.15], severe hypertension [1.40-2.20]), and fetal growth (small-for-gestational-age infants [1.12-1.32] or low birth weight [1.18-1.39]). These associations were independent of mean blood pressure level. In women with hypertension, there were stronger associations with maternal outcomes but no consistent pattern for perinatal outcomes. CONCLUSIONS: Future work should aim to confirm whether BPV could be useful for risk stratification prospectively in pregnancy, and should determine the optimal management path for those women identified at increased risk of adverse outcomes.

ABSTRACT

Postpartum care of hypertensive disorders of pregnancy (HDP) often extends only 6 weeks after delivery in low-income countries. This multicenter observational cohort study was conducted to determine 3-month postpartum outcomes of HDP in Tanzania. Of 309 consecutive women admitted to 3 public hospitals, five (1.7 %) died within 3 months. Of the remaining 304, 292 (94.5 %) returned for 3-month follow-up visit and 41.1 % (95 % CI: 35.6 %-46.9 %) had persistent postpartum hypertension. The strongest independent predictor of hypertension persistence was reduced eGFR at delivery (aOR = 2.1[1.01,4.4]). Postpartum follow-up should routinely be extended to 3 months in all women with HDP to diagnose hypertension and prevent cardiovascular disease.

ABSTRACT

BACKGROUND: Cardiovascular disease is the leading cause of mortality in women. Pregnancy is an ideal period to implement cardiovascular prevention strategies as women seek medical help. We aimed to develop a predictive model to identify women at increased risk for chronic hypertension (CH) based on information collected in the index pregnancy. METHODS: Cohort of 26 511 women seen in 2 consecutive pregnancies. Included were women without CH, with information on maternal characteristics and blood pressure at 11 to 13 weeks' gestation, and the development of preeclampsia or gestational hypertension (GH) in the index pregnancy. Logistic regression models were fitted for the prediction of the development of future CH by the 20th week of the subsequent pregnancy. The performance of screening and risk calibration of the model were assessed. RESULTS: In this study 1560 (5.9%) women developed preeclampsia or GH (index pregnancy), and 215 (0.8%) developed future CH, with a median of 3.0 years later. Predictors of development of future CH were maternal age, weight, and blood pressure; Black and South Asian ethnicity; family history of preeclampsia; parity; and development of preeclampsia or GH. Preeclampsia or GH detected 52.1% (45.2%-58.9%) of future CH. At a screen-positive rate of 10%, a model including maternal characteristics, early pregnancy blood pressure, and development of preeclampsia or GH detected 73.5% (67.1-79.3) of future CH. CONCLUSIONS: Early pregnancy maternal characteristics, blood pressure, and development of preeclampsia or GH identify three-fourths of women at risk for future CH.

ABSTRACT

BACKGROUND: Adverse pregnancy outcomes (APO), such as preeclampsia (PE) and gestational diabetes (GDM) are substantial risk factors for cardiovascular disease (CVD) later in life. Identifying these high-risk female individuals during pregnancy offers the possibility of preventing long-term CVD and chronic kidney disease via a structured therapeutic and surveillance plan. We aimed to evaluate the current practice of postpartum care in women after APO and the impact on the women's awareness about their future risk for CVD. METHODS: Women diagnosed with PE and GDM at the University Hospital of St. Poelten/Lilienfeld between 2015-2020 were identified and participated in a structured telephone interview about postpartum medical care and knowledge about the impact of APOs on long-term cardiovascular health. RESULTS: Of 161 out of the 750 women contacted, 29% (n = 46) were diagnosed with PE and 71% (n = 115) with GDM. One third of all women and up to 44% of women diagnosed with PE, were unaware that APOs are related to CVD. Women diagnosed with PE were less likely to receive postpartum care information than those with GDM (30.4% vs. 49.6%, p = 0.027), and only one third of all women after APOs were counselled by a physician or healthcare professional. Of the women 50% received recommendations regarding lifestyle changes after delivery; significantly more women with GDM than women with PE (54% vs. 37%, p = 0.05). Only 14% had at least one long-term follow-up. CONCLUSION: This study identified a significant deficit of structured postpartum care and a lack of awareness among women after APO and their healthcare providers about the increased risk of long-term CVD.
