PURPOSE: Postpartum hypertension (PPHTN) poses increased risks, including of stroke. Timely assessment and management by clinicians is imperative but challenging. Team-based care involving pharmacists has shown promise in improving blood pressure control, yet its application in PPHTN management remains unexplored. The objective of this study was to determine the impact and feasibility of an interprofessional model for PPHTN management. SUMMARY: This initiative implemented a novel interprofessional model at a safety-net hospital to address previous workflow limitations. Ambulatory care pharmacists collaborated with an obstetric nurse (OBRN) and a maternal fetal medicine specialist to manage high-risk patients with PPHTN utilizing electronic consults (e-consults). Data collection and symptom assessment were completed by an OBRN via telemedicine appointments. Pharmacists employed a collaborative practice agreement based on a preestablished algorithm to initiate medications. Data on patient demographics, consult volume, prescriptions, and pharmacist comfort were collected during the first quarter of full integration. Pharmacists completed 55 e-consults and generated 54 prescriptions. The average time spent per chart review was 12.5 minutes, and the average time to completion of e-consults was 54 minutes. Forty-five unique patients received care, who were primarily non-English-speaking and non-Hispanic Black patients. Pharmacists reported moderate to high comfort levels in managing PPHTN based on the algorithm and provided feedback leading to workflow adjustments. CONCLUSION: Integration of pharmacists into PPHTN care enables prompt medication initiation and titration. This innovative model, involving remote blood pressure monitoring, telemedicine visits with an OBRN, and e-consults completed by pharmacists, ensures delivery of timely and equitable care and improved access across a diverse population.
RESUMO
PURPOSE: The utilization of remote patient monitoring (RPM) with home blood pressure monitoring has shown improvement in blood pressure control and adherence with follow-up visits. Patient perceptions regarding its use in the obstetric population have not been widely studied. The aim of this study was to assess patients' knowledge about hypertensive disorders of pregnancy and perceptions and satisfaction of the RPM program. METHODS: Descriptive analysis of survey responses of patients with PPHTN enrolled into the RPM program for 6 weeks after delivery between October 2021 and April 2022. Surveys were automatically administered at 1-, 3-, and 6-week postpartum. Responses were further compared between Black and non-Black patient-reported race. RESULTS: 545 patients received the RPM program. Of these, 306 patients consented to data collection. At 1 week, 88% of patients that responded reported appropriately that a blood pressure greater than 160/110 is abnormal. At 3 weeks, 87.4% of patients responded reported they were "very" or "somewhat" likely to attend their postpartum follow-up visits because of RPM. At 6 weeks, 85.5% of the patients that responded were "very" or "somewhat" satisfied with the RPM program. Responses were not statistically different between races. CONCLUSIONS: Majority of postpartum patients enrolled in the RPM program had correct knowledge about hypertension. In addition, patients were highly satisfied with the RPM program and likely to attend postpartum follow-up based on responses. Further research is warranted to validate these findings and to address any barriers for patients who did not utilize the program.

BACKGROUND: The aim of this study was to evaluate the association between early postpartum weight change and (1) hospital readmission and (2) 2-week blood pressure trajectory. METHODS AND RESULTS: This retrospective study cohort included 1365 individuals with a hypertensive disorder of pregnancy enrolled in a postpartum hypertension remote monitoring program. Exposure was percentage weight change from delivery to first weight recorded within 10 days postpartum. We first modeled likelihood of hospital readmission within 8 weeks postpartum using logistic regression adjusting for age, race, insurance, type of hypertensive disorder of pregnancy, early body mass index, gestational weight gain, mode of delivery, and any discharge antihypertensive medications. We then performed case-control analysis additionally matching in a 1:3 ratio on breastfeeding, early body mass index, discharge on antihypertensive medications, and days between weight measurements. Both analytic approaches were repeated, limiting to readmissions attributable to hypertension or heart failure. Finally, we compared blood pressure trajectories over first 2 weeks postpartum. Individuals who did not lose weight in the early postpartum period had more admissions compared with weight loss groups (group 3: 14.1% versus group 2: 5.8% versus group 1: 4.5%). These individuals had 4 times the odds of postpartum readmissions (adjusted odds ratio [aOR], 3.9 [95% CI, 1.8-8.6]) to 7 (aOR, 7.8 [95% CI, 2.3-26.5]) compared with those with the most weight loss. This association strengthened when limited to hypertension or heart failure readmissions. These individuals also had more adverse postpartum blood pressure trajectories, with significant differences by weight change group. CONCLUSIONS: Weight change is readily accessible and may identify individuals at high risk for postpartum readmission following a hypertensive disorder of pregnancy who could benefit from targeted interventions.

BACKGROUND: Hypertensive disorders of pregnancy are increasing in prevalence and a leading cause of early postpartum readmissions. Stricter blood pressure target goals for treatment of hypertension during pregnancy have recently been proposed, however, the treatment goals for management of postpartum hypertension are less well established. OBJECTIVE: We sought to evaluate the clinical factors associated with early postpartum readmissions for hypertensive disease and to evaluate blood pressure thresholds associated with these readmissions. STUDY DESIGN: We conducted a retrospective cohort study of women delivering at a tertiary care center between January 2018 and May 2022 who experienced a hospital readmission for postpartum hypertension or new onset postpartum preeclampsia. Charts were reviewed for clinical and sociodemographic data. Patients with early readmission (<72 hours after discharge) were compared with patients readmitted after 3 days of initial discharge. Data were analyzed using chi-square, Student t test, Mann-Whitney U test, and logistic regression where appropriate. The P value <.05 was considered significant. RESULTS: During the study period, 23,372 deliveries occurred. Postpartum readmission due to worsening of a known diagnosis of hypertension or new onset postpartum preeclampsia occurred in 1.1% and 0.49% respectively. Patients with early readmission were more likely to have hypertensive disorders of pregnancy as the indication for delivery. Among patients readmitted, 93% had 2 or more systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg, and 73% had blood pressure of either systolic between 130 and 139 mmHg or diastolic between 80 and 89 mmHg within 24 hours before initial discharge. Only 27 patients met criteria (blood pressure ≥160/110 mmHg on >1 vitals check during their hospitalization) to be started on antihypertensives before initial delivery discharge; of those 25 (93%) were discharged with a new prescription for an antihypertensive. After controlling for confounding variables, predischarge blood pressure between 130-140 mmHg/80-90 mmHg (adjusted odds ratio, 2.4 [1.5-4.0]) was associated with an increased likelihood of early readmission. CONCLUSION: Patients with delivery for hypertensive disorders of pregnancy and predischarge blood pressure ≥140/90 mmHg were less likely to have an early readmission within 3 days of initial discharge, however, patients with predischarge blood pressure 130-139 mmHg/80-89 mmHg were more likely to have an early readmission for hypertensive disorders of pregnancy and postpartum preeclampsia. Further research is indicated to evaluate interventions to prevent postpartum readmission in patients at high risk for persistent hypertension or new onset postpartum preeclampsia.
RESUMO
Patients with hypertensive disorders of pregnancy (HDP) are at increased risk of maternal-fetal complications and represent the third leading cause of maternal mortality. To date, it is known that women experiencing this condition during pregnancy have a higher future risk of cardiovascular events (CVD). Our objective was to report the incidence of new-onset hypertension in the postpartum period. We conducted a cohort study in high-risk pregnant patients who underwent ambulatory blood pressure monitoring (ABPM) between weeks 20-30. Patients were categorized as normotensive (NT) or gestational hypertensive (GH), excluding those with chronic hypertension, and were followed until the end of pregnancy with a postpartum assessment after 3months. Patients with HDP (39%) had a higher incidence of preeclampsia and newborns with low birth weight and preterm birth. A total of 177 pregnant women were analyzed for the primary outcome. Among those with GH, 33.3% vs 17.2% of NT (P=.014) reported new-onset hypertension. The odds ratio for developing new-onset hypertension was 2.3 (95%CI: 1.20-4.77), for those with GH. In conclusion, pregnant patients with GH assessed by ABPM between 20-30weeks are at higher risk of developing new-onset hypertension in the postpartum period, emphasizing the need for closer monitoring and control to prevent future cardiovascular complications.
RESUMO
BACKGROUND: Hypertensive disorders of pregnancy are a main cause of maternal morbidity and mortality in the United States and worldwide, and it is estimated that approximately 60% of maternal deaths in the United States occur during the postpartum period. The utilization of telehealth modalities such as home blood pressure monitoring has shown improvement in blood pressure control and adherence with follow up visits. Our study sought to determine if standardized education improved patient hypertension knowledge and if this when combined with home blood pressure telemonitoring increased participants' postpartum self-blood pressure monitoring and postpartum visit attendance. METHODS: This is an Institutional Review Board approved prospective cohort study conducted at the University of Mississippi Medical Center. Women with a hypertensive disorder of pregnancy who met the inclusion criteria and provided written informed consent to participate were enrolled. Participants received a baseline pre-education questionnaire designed to assess their knowledge of their hypertensive diagnosis, hypertension management, and postpartum preeclampsia (PreE). Participants then received standard education, a blood pressure monitor, and were scheduled a follow-up visit during the first 10 days following discharge. Remote home blood pressure monitoring was performed via text messages and voice calls for 6-weeks postpartum. At the conclusion of the study, participants repeated their original questionnaire. RESULTS: 250 women provided informed consent to participate in the study and were included in this analysis. Relative to the baseline survey, there was a significant increase (p = 0.0001) in the percentage of correct responses. There was not an association between study engagement and percentage of correct responses on end of study questionnaire (p = 0.33) or postpartum visit attendance (p = 0.69). Maternal age was found to drive study engagement, even when adjusted for community-level distress (p = 0.03) and maternal race (p = 0.0002). CONCLUSION: Implementing a standardized postpartum education session was associated with improvement in patient's knowledge. Further studies are needed with more longitudinal follow up to assess if this program would also result in improved long-term outcomes and decreased hospital readmission rates. TRIAL REGISTRATION: NCT04570124.

OBJECTIVE: This study examined whether use of bedside medication delivery (Meds to Beds, M2B) or on-campus pharmacy at discharge was associated with improved postpartum blood pressure (BP) control compared to outside pharmacy use in patients with hypertensive disorders of pregnancy (HDP). STUDY DESIGN: This was a secondary analysis of 357 patients with HDP enrolled in STAMPP-HTN (Systematic Treatment and Management of Postpartum Hypertension Program) who were discharged from delivery admission with antihypertensives between October 2018 and June 2020. Patients were grouped by discharge medication location: M2B/on-campus pharmacy (on-site) versus outside pharmacy (off-site). MAIN OUTCOME MEASURES: The primary outcome was BP values at the immediate postpartum visit. Secondary outcomes included six-week visit BP values, attendance at both visits, and readmission within six weeks. RESULTS: Median BP values were no different based on pharmacy location at immediate postpartum visit for both systolic ((135 [IQR 127, 139] on-site vs 137 [127, 145] off-site, p = 0.22) and diastolic (81 [74, 91] vs 83 [76, 92], p = 0.45) values. Similar findings were noted at six weeks. Patients who used an off-site pharmacy had higher attendance rates at the immediate postpartum visit but this difference was attenuated after adjusting for group differences (OR 0.67 [95 % CI 0.37-1.20], p = 0.18). Readmission rates were also not different between groups (12.2 % on-site vs 15.8 % off-site pharmacy, p = 0.43). CONCLUSION: In the context of a preexisting multicomponent HDP quality improvement program, on-campus pharmacy and bedside medication delivery use was not associated with additional improvement in postpartum BP control, follow-up rates, or readmission rates.

BACKGROUND: In nonpregnant adults, poor sleep is associated with higher blood pressure. Poor sleep is common in the postpartum period and is often attributed to infant caretaking needs. However, its effects on cardiovascular health in individuals with a hypertensive disorder of pregnancy are unknown. OBJECTIVE: This study aimed to determine the effect of a neonatal sleep intervention on maternal postpartum blood pressure in individuals with a hypertensive disorder of pregnancy. STUDY DESIGN: In this single-institution pilot randomized controlled trial from July 2021 to March 2022, 110 individuals with a hypertensive disorder of pregnancy were randomized to receive a neonatal sleep intervention (SNOO responsive bassinet) plus usual care of safe sleep education (n=54) or usual care alone (n=56). Remote follow-up visits were conducted at 1 week, 6 weeks, and 4 months after delivery and involved blood pressure and weights, sleep and mood questionnaires, and self-reported infant and maternal sleep logs. Based on institutional data, the sample size had 80% power to detect a 4.5-mm Hg difference in the primary outcome of mean arterial pressure at 6 weeks after delivery. RESULTS: Baseline characteristics were similar between the arms. At 1 week after delivery, the intervention arm had lower mean arterial pressure and less antihypertensive medication use than the control arm (99±10 vs 103±7 mm Hg [P=.04] and 23% vs 35% [P=.15], respectively). At 6 weeks after delivery, mean arterial pressure was similar between arms (93±8 vs 94±8 mm Hg; P=.54), but there was a lower rate of antihypertensive use in the intervention arm (15% vs 26%; P=.19). Scores from maternal sleep and mood questionnaires at 6 weeks after delivery and self-reported infant and maternal sleep duration at 6 weeks and 4 months after delivery were similar between arms (P>.05). CONCLUSION: The SNOO responsive bassinet as a neonatal sleep intervention did not result in improved mean arterial pressure at 6 weeks after delivery after hypertensive disorders of pregnancy.

OBJECTIVE: We aimed to examine the association of clinical risk factors and placental lesions, in gestations complicated with preeclampsia, with the need for antihypertensive treatment in the early postpartum period. METHODS: The computerized files and placental reports of all singleton deliveries at 24.0-42.0 weeks complicated by preeclampsia were reviewed between January 2013 and October 2020. Obstetric characteristics and placental lesions were compared between patients who required antihypertensive treatment in the early postpartum period and those who did not (control group). Placentas were classified into maternal and fetal malperfusion lesions and inflammatory responses. RESULTS: As compared to controls (n = 200), the anti-hypertensive treatment group (n = 95) was characterized by increased rates of preterm birth, preeclampsia with severe features, and cesarean delivery (p < 0.001 for all). More placental hematomas (p = 0.01) and placental maternal vascular lesions (p = 0.03) were observed in the antihypertensive treatment group as compared to controls. In adjusted logistic regression analysis, gestational age (OR 0.86, 95% CI 0.79-0.93, p = 0.001) and preeclampsia with severe features (OR 8.89, 95% CI 3.18-14.93 p < 0.001) were found to be independently associated with the need for postpartum antihypertensive treatment. CONCLUSION: Placental vascular lesions are more common in preeclamptic patients who need postpartum antihypertensive treatment, yet only early onset of preeclampsia with severe features was found to be independently associated with antihypertensive treatment in the early postpartum period.
RESUMO
Magnesium sulfate reduces the risk for eclamptic seizures antepartum, intrapartum, and in the immediate postpartum period, however, there are no studies that have evaluated the benefits and risks of magnesium sulfate among women with late postpartum severe hypertension only. Juxtaposed on this clinical uncertainty is the increased incidence of severe hypertension owing to a rise in pregnancies complicated by advanced maternal age, obesity, chronic hypertension, diabetes, and recent protocols for intensive monitoring of blood pressure in the postpartum period. These factors have led to a significant increase in postpartum presentations for the evaluation and management of severe hypertension, in some cases leading to postpartum readmissions for administration of antihypertensive therapy and magnesium sulfate without data demonstrating clear clinical benefit. Postpartum readmissions can have several negative consequences, including interfering with early bonding with a newborn, breastfeeding, and use of scarce healthcare resources. In addition, magnesium sulfate is associated with risks for serious cardiorespiratory depression and bothersome side effects and can delay determining the optimal antihypertensive regimen, which is typically the most pressing clinical need during postpartum presentations of late-postpartum severe hypertension. Eclampsia that occurs more than 48 hours after delivery is rare (constitutes 16% of all cases of eclampsia) and is most commonly preceded by headaches or other cerebral symptoms. In this commentary, we propose an approach to evaluating and managing patients with late postpartum severe hypertension aimed at identifying those women at highest risk for end-organ injury. We recommend that the short- and long-term focus for all patients with severe hypertension should be the optimal management of blood pressures with a goal of close outpatient monitoring when logistically feasible and clinically appropriate. We suggest reserving magnesium sulfate therapy for the subset of patients with neurologic symptoms who may be at highest risk for an eclamptic seizure.

The aim of this study was to investigate the prevalence and risk factors of new-onset postpartum hypertension (PPHTN), defined as new-onset hypertension during the postpartum period, among women without a history of hypertension during pregnancy and labor. A multicenter retrospective study was conducted using clinical data of women who delivered at term between 2011 and 2018 at 12 maternity hospitals. A total of 18,295 normotensive women were eligible, after excluding those with hypertensive disorders of pregnancy or hypertension during labor. New-onset PPHTN was defined as multiple blood pressure readings of ≥ 140/90 mmHg between 1 d and 4 weeks postpartum among normotensive women throughout pregnancy. Multivariate regression analyses were performed to evaluate the risk factors for new-onset PPHTN. Among the 18,295 normotensive women, 227 (1.2%) presented with new-onset PPHTN. The prevalence was higher in women who delivered via cesarean section than in those who delivered vaginally (7.0% and 1.0%, respectively). The independent risk factors were maternal age ≥ 35 years (adjusted odds ratio 1.67, 95% confidence interval [1.10-2.53]), nulliparity (1.83 [1.24-2.71]), high normal blood pressure (systolic blood pressure [SBP] 120-129 and diastolic blood pressure [DBP] < 80) at the last prenatal check-up (1.96 [1.23-3.13]), elevated blood pressure (SBP 130-139 and/or DBP 80-89) (6.42 [4.15-9.95]), urinary protein 1+ (1.99 [1.27-3.11]), scheduled cesarean section (4.05 [1.69-9.69]), and emergency cesarean section (10.02 [5.10-19.70]). New-onset PPHTN was observed in 1.2% of the normotensive women, with women who delivered via cesarean section having the highest risk. Close postpartum blood pressure monitoring may be required for women with multiple risk factors to identify new-onset PPHTN in a timely manner and reduce adverse maternal consequences.

BACKGROUND: Preeclampsia is an obstetrical disorder, which complicates 3% to 6% of pregnancies and contributes to 21.6% of readmissions in the postpartum period. The optimal strategy for inpatient monitoring of blood pressures to minimize readmissions for postpartum patients with hypertensive disorders is not known. We hypothesized that extended monitoring of postpartum patients with hypertensive disorders of pregnancy for at least 36 hours after the last blood pressure that was ≥150/100 mm Hg would result in decreased readmission rates for preeclampsia with severe features compared with those who were not observed by these blood pressure goals. OBJECTIVE: This study aimed to evaluate whether extended inpatient monitoring of postpartum patients with hypertensive disorders of pregnancy for at least 36 hours after their last blood pressure that was ≥150/100 mm Hg would improve readmission rates for preeclampsia with severe features within 6 weeks of delivery. STUDY DESIGN: This was a retrospective cohort study in patients with a singleton pregnancy and a diagnosis of a hypertensive disorder of pregnancy at their delivery admission or at any point during pregnancy who delivered 1 year before and 1 year after the implementation of extended inpatient monitoring of postpartum hypertension. The primary outcome was readmission for preeclampsia with severe features within 6 weeks of delivery. The secondary outcomes were length of stay during first admission, number of readmissions for any indication, intensive care unit admission, postpartum day at readmission, median systolic blood pressure in the 24-hour period before discharge, median diastolic blood pressure in the 24-hour period before discharge, intravenous antihypertensive medication required during first admission, and intravenous antihypertensive medication required during second admission. Univariable analysis was performed for the association between baseline maternal characteristics and the primary outcome. Multivariable analysis was performed, adjusting for baseline maternal characteristic differences between exposure groups. RESULTS: A total of 567 patients met the inclusion criteria of which 248 patients delivered before and 319 delivered after the implementation of extended monitoring. For baseline characteristics, the extended monitoring group had a significantly higher proportion of patients who were non-Hispanic Black and Hispanic, more diagnoses of hypertensive disorders and/or diabetes mellitus at the time of admission for delivery, a difference in the distribution of hypertensive diagnoses at the time of discharge from the first admission, and fewer discharged patients from their first admission on labetalol than the preintervention group. In a univariable analysis of the primary outcome, there was a significantly increased risk of readmission for preeclampsia with severe features in the extended monitoring group (62.5% vs 96.2% of total readmissions; P=.004). In multivariable analysis, patients in the extended monitoring group were more likely to be readmitted for preeclampsia with severe features than patients in the preintervention group (adjusted odds ratio, 3.45; 95% confidence interval, 1.03-11.5; P=.044). CONCLUSION: Extended monitoring with a strict blood pressure goal of <150/<100 mm Hg did not decrease readmissions for preeclampsia with severe features in patients with a previous diagnosis of a hypertensive disorder of pregnancy.

BACKGROUND: Hypertension disorders are relatively common in pregnant women and often persist in the postpartum period. Few studies are available regarding the self-management of postpartum hypertension via the eHealth system. This study aimed to develop a self-management eHealth system for women with postpartum hypertension during the postpartum period. METHODS: We adopted a multi-platform system for this research, not only for use on the web interface but also on smartphones. The proposed system possessed three features: (1) the population was limited to postnatal women with hypertension; (2) a self-care record, which allowed postnatal women to keep track of their blood pressure, pulse, weight, medication record, exercise record, and risk factor assessment; and (3) through this system, nurse-midwives could keep track of postnatal women's health status maintaining the complete record and could communicate directly with the users if their health monitor values reach beyond normal range. RESULTS: Thirty-nine postnatal women with postpartum hypertension were recruited to the study. A survey to evaluate the usability and satisfaction of the proposed e-health application system was completed by these women. The usability rate of the system reached 92.4% (46.2% satisfied and 46.2% strongly satisfied), which suggested that the system was helpful to the users. The satisfaction rate of the system reached 94.9% (43.6% satisfied and 51.3% strongly satisfied), which suggested that the system was acceptable to the users. CONCLUSION: This proposed system has been developed completely with user experience and professional advice from experts. Postnatal women could gain important postpartum-related knowledge and access their related health records and other information easily via their smartphones or computers. During the postpartum period, an eHealth application system can effectively assist women with hypertension to manage their blood pressure and related postnatal healthcare issues.

OBJECTIVE: To test the feasibility of a randomised trial of home blood pressure monitoring paired with a remote lifestyle intervention (Heart Health 4 New Moms) versus home blood pressure monitoring alone versus control in individuals with a hypertensive disorder of pregnancy in the first year postpartum. DESIGN: Single-blinded three-arm randomised clinical trial. SETTING: Two tertiary care hospitals and a community organisation. POPULATION: Postpartum overweight and obese individuals with a hypertensive disorder of pregnancy and without pre-pregnancy hypertension or diabetes. METHODS: We assessed the feasibility of recruitment and retention of 150 participants to study completion at 1-year postpartum with randomisation 1:1:1 into each arm. Secondary aims were to test effects of the interventions on weight, blood pressure and self-efficacy. RESULTS: Over 23 months, we enrolled 148 of 400 eligible, screened individuals (37%); 28% black or other race and mean pre-pregnancy body mass index (BMI) of 33.4 ± 6.7 kg/m2 . In total, 129 (87%) participants completed the 1-year postpartum study visit. Overall, 22% of participants developed stage 2 hypertension (≥140/90 mmHg or on anti-hypertensive medications) by 1 year postpartum. There were no differences in weight or self-efficacy across the study arms. CONCLUSION: In this pilot, randomised trial, we demonstrate feasibility of HBPM paired with a lifestyle intervention in the first year postpartum. We detected high rates of ongoing hypertension, emphasising the need for the development of effective interventions in this population.

BACKGROUND: High-quality evidence to inform the management of postpartum hypertension, including the optimal blood pressure threshold to initiate therapy, is lacking. Randomized trials have been conducted in pregnancy, but there are no published trials to guide management in the postpartum period. OBJECTIVE: This study aimed to test the hypothesis that initiating antihypertensive therapy in the postpartum period at a threshold of 140/90 mm Hg would result in less maternal morbidity than initiating therapy at a threshold of 150/95 mm Hg. STUDY DESIGN: We performed a pragmatic multicenter randomized controlled trial of patients aged 18 to 55 years with postpartum hypertension. Patients with chronic hypertension, gestational hypertension, and preeclampsia without severe features were randomized to 1 of 2 blood pressure thresholds to initiate treatment: persistent blood pressure of ≥150/95 mm Hg (institutional standard or "liberal control" group) or ≥140/90 mm Hg (intervention or "tight control" group). Our primary outcome was composite maternal morbidity defined as: severe hypertension (blood pressure ≥160/110 mm Hg) or preeclampsia with severe features, the need for a second antihypertensive agent, postpartum hospitalization >4 days, and maternal adverse outcome secondary to hypertension as evidenced by pulmonary edema, acute kidney injury (creatinine level ≥1.1 mg/dL), cardiac dysfunction (eg, elevated brain natriuretic peptide level) or cardiomyopathy, posterior reversible encephalopathy syndrome, cerebrovascular accident, or admission to an intensive care unit. Secondary outcomes included hospital readmission for hypertension, persistence of hypertension beyond 14 days, medication side effects, and time to blood pressure control. We calculated that 256 women would provide 90% power to detect a relative 50% reduction in the primary outcome from 36% in the standard blood pressure threshold group to 18%, with a 2-sided alpha set at 0.05 for significance. Data were analyzed using R statistical software. RESULTS: A total of 256 patients were randomized, including 128 to the "tight control" group (140/90 mm Hg) and 128 to the "liberal control" group (150/95 mm Hg). Patients in the "tight control" group had a higher body mass index at delivery (37.1±9.4 vs 34.9±8.1; P=.04); other demographic and obstetrical characteristics were similar between groups. The rate of the primary outcome was similar between groups (8.6% vs 11.7%; P=.41; relative risk, 0.73; 95% confidence interval, 0.35-1.53). The rates of all secondary outcomes and the individual components of the primary and secondary outcome measures were also similar between groups. CONCLUSION: In the postpartum period, initiation of antihypertensive therapy at a lower blood pressure threshold of 140/90 mm Hg did not decrease maternal morbidity or improve outcomes compared with a threshold of 150/95 mm Hg.

BACKGROUND: Postpartum hypertension is the leading cause of postpartum readmission and has long-lasting cardiovascular effects. Black patients have higher incidence rates of hypertensive disorders after delivery and subsequent severe maternal morbidity. Neighborhood advantage, a marker of social determinants of health, has not been studied concerning postpartum hypertension. Moreover, the interplay between race and neighborhood advantage and their effect on postpartum hypertension have not been previously explored. OBJECTIVE: This study aimed to evaluate the association between neighborhood-level social determinants of health and postpartum hypertension and explore whether these factors explain previously documented racial disparities. STUDY DESIGN: This study included a retrospective cohort of people enrolled in a remote monitoring program of postpartum hypertension at the time of delivery within 1 health network from March 2019 to September 2021. Patients were eligible for enrollment after a diagnosis of hypertensive disorder during pregnancy or delivery. We further limited the cohort to self-reported Black and White patients with blood pressures recorded at 3 weeks and 6 weeks postpartum. The neighborhood advantage for each person at the time of delivery was classified using the area deprivation index, an accepted surrogate of social determinants of health and our primary exposure. The secondary exposure was self-reported race. Study outcomes of interest were hypertensive status (stage 1 hypertension: ≥130 to 139/80 to 89 mm Hg; stage 2 hypertension: ≥140/90 mm Hg) at 3 and 6 weeks after delivery. In addition, hypertensive status by neighborhood area deprivation index using logistic regression was molded. In secondary analyses, a case-control cohort matched on the area deprivation index was created, and conditional logistic regression was used to evaluate race. Finally, mixed-effects models modeling hypertension by race and clustering within the area deprivation index were used. RESULTS: Of 4193 people enrolled, 2722 were Black or White and had blood pressure data recorded at 3 weeks after delivery, and 1126 had blood pressure data recorded at 6 weeks after delivery. After accounting for prenatal body mass index, smoking status, type of hypertension, and antihypertensives prescribed at discharge, persons living in the most disadvantaged neighborhoods were twice as likely (adjusted odds ratio, 2.03; 95% confidence interval, 1.53-2.69) to develop stage 2 hypertension at 21 days after delivery and 1.67 times more likely (95% confidence interval, 1.06-2.64) to develop stage 2 hypertension at 6 weeks after delivery than persons living in the most advantaged neighborhoods. Both associations were attenuated after adjusting for race. When people with stage 2 hypertension were matched on area deprivation index with normotensive counterparts, Black patients were still 3 to 4 times more likely to develop stage 2 hypertension at 3 (adjusted odds ratio, 3.00; 95% confidence interval, 1.95-4.63) and 6 (adjusted odds ratio, 4.61; 95% confidence interval, 2.05-10.36) weeks after delivery. This association remained after clustering within a neighborhood at 3 (adjusted odds ratio, 3.12; 95% confidence interval, 2.41-4.06) and 6 (adjusted odds ratio, 2.99; 95% confidence interval, 1.96-4.54) weeks after delivery. There was no significant difference in stage 1 hypertension. CONCLUSION: Neighborhood advantage was associated with the development of persistent hypertension at 3 and 6 weeks after delivery. This association did not explain the racial disparity in sustained high blood pressure.

BACKGROUND: A significant proportion of women with preeclampsia (PE) exhibit persistent postpartum hypertension (PHTN) at 3 months postpartum associated with cardiovascular morbidity. This study aimed to screen patients with PE to identify the high-risk population with persistent PHTN. METHODS: This retrospective cohort study enrolled 1,000 PE patients with complete parturient and postpartum blood pressure (BP) profiles at 3 months postpartum. The enrolled patients exhibited new-onset hypertension after 20 weeks of pregnancy, while those with PE superimposed upon chronic hypertension were excluded. Latent class cluster analysis (LCCA), a method of unsupervised learning in machine learning, was performed to ascertain maternal exposure clusters from eight variables and 35 subordinate risk factors. Logistic regression was applied to calculate odds ratios (OR) indicating the association between clusters and PHTN. RESULTS: The 1,000 participants were classified into three exposure clusters (subpopulations with similar characteristics) according to persistent PHTN development: high-risk cluster (31.2%), medium-risk cluster (36.8%), and low-risk cluster (32.0%). Among the 1,000 PE patients, a total of 134 (13.4%) were diagnosed with persistent PHTN, while the percentages of persistent PHTN were24.68%, 10.05%, and 6.25% in the high-, medium-, and low-risk clusters, respectively. Persistent PHTN in the high-risk cluster was nearly five times higher (OR, 4.915; 95% confidence interval (CI), 2.92-8.27) and three times (OR, 2.931; 95% CI, 1.91-4.49) than in the low- and medium-risk clusters, respectively. Persistent PHTN did not differ between the medium- and low-risk clusters. Subjects in the high-risk cluster were older and showed higher BP, poorer prenatal organ function, more adverse pregnancy events, and greater medication requirement than the other two groups. CONCLUSION: Patients with PE can be classified into high-, medium-, and low-risk clusters according to persistent PHTN severity; each cluster has cognizable clinical features. This study's findings stress the importance of controlling persistent PHTN to prevent future cardiovascular disease.

OBJECTIVE: To investigate the perinatal outcome of postpartum hypertension in pregnant women with gestational diabetes (GDM). METHODS: A total of 100 puerperae who gave birth in our hospital from March 2018 to January 2020 were retrospectively analyzed. Among them, 50 patients were puerperae with postpartum hypertension (experimental group), and 50 puerperae had normal postpartum blood pressure (control group). Before delivery, fasting, postprandial and bedtime blood glucose, glycosylated hemoglobin, and urine glucose were compared between the two groups. RESULTS: Before delivery, the experimental group observed significantly higher fasting, postprandial, and bedtime blood glucose, glycosylated hemoglobin, and urine glucose than the control group (P<0.05). A notable decline in natural delivery rate was witnessed in the experimental group (P<0.05). The two groups presented no significant differences in neonatal outcomes, neonatal blood glucose and blood pressure, maternal blood pressure at 30 weeks and 34 weeks of pregnancy, and blood lipid levels during pregnancy (P>0.05). CONCLUSION: Postpartum hypertension in pregnant women with GDM results in a low probability of natural birth and it has a slight impact on the fetus.
