ABSTRACT

Preeclampsia and peripartum cardiomyopathy (PPCM) are significant obstetric problems that can arise during or after pregnancy. Both are known to be causes of maternal mortality and morbidity. Several recent studies have suggested a link between preeclampsia and the pathophysiology of PPCM. However, the common thread that connects the two has yet to be thoroughly and fully articulated. Here, we investigate the complex dynamics of preeclampsia and PPCM in this review. Our analysis focuses mainly on inflammatory and immunological responses, endothelial dysfunction as a shared pathway, and potential genetic predisposition to both diseases. To begin, we will look at how excessive inflammatory and immunological responses can lead to clinical symptoms of both illnesses, emphasizing the role of proinflammatory cytokines and immune cells in modifying vascular and tissue responses. Second, we consider endothelial dysfunction to be a crucial point at which endothelial damage and activation contribute to pathogenesis through increased vascular permeability, vascular dysfunction, and thrombus formation. Finally, we examine recent information suggesting genetic predispositions to preeclampsia and PPCM, such as genetic variants in genes involved in the management of blood pressure, the inflammatory response, and heart structural integrity. With this synergistic study, we seek to encourage more research and creative therapy solutions by emphasizing the need for an interdisciplinary approach to understanding and managing the connection between preeclampsia and PPCM.

ABSTRACT

OBJECTIVE: To evaluate maternal and neonatal outcomes by type of antihypertensive used in participants of the CHAP (Chronic Hypertension in Pregnancy) trial. METHODS: We conducted a planned secondary analysis of CHAP, an open-label, multicenter, randomized trial of antihypertensive treatment compared with standard care (no treatment unless severe hypertension developed) in pregnant patients with mild chronic hypertension (blood pressure 140-159/90-104 mm Hg before 20 weeks of gestation) and singleton pregnancies. We performed three comparisons based on medications prescribed at enrollment: labetalol compared with standard care, nifedipine compared with standard care, and labetalol compared with nifedipine. Although active compared with standard care groups were randomized, medication assignment within the active treatment group was not random but based on clinician or patient preference. The primary outcome was the occurrence of superimposed preeclampsia with severe features, preterm birth before 35 weeks of gestation, placental abruption, or fetal or neonatal death. The key secondary outcome was small for gestational age (SGA) neonates. We also compared medication adverse effects between groups. Relative risks (RRs) and 95% CIs were estimated with log binomial regression to adjust for confounding. RESULTS: Of 2,292 participants analyzed, 720 (31.4%) received labetalol, 417 (18.2%) received nifedipine, and 1,155 (50.4%) received no treatment. The mean gestational age at enrollment was 10.5±3.7 weeks; nearly half of participants (47.5%) identified as non-Hispanic Black; and 44.5% used aspirin. The primary outcome occurred in 217 (30.1%), 130 (31.2%), and 427 (37.0%) in the labetalol, nifedipine, and standard care groups, respectively. Risk of the primary outcome was lower among those receiving treatment (labetalol use vs standard adjusted RR 0.82, 95% CI, 0.72-0.94; nifedipine use vs standard adjusted RR 0.84, 95% CI, 0.71-0.99), but there was no significant difference in risk when labetalol was compared with nifedipine (adjusted RR 0.98, 95% CI, 0.82-1.18). There were no significant differences in SGA or serious adverse events between participants receiving labetalol and those receiving nifedipine. CONCLUSION: No significant differences in predetermined maternal or neonatal outcomes were detected on the basis of the use of labetalol or nifedipine for treatment of chronic hypertension in pregnancy.

ABSTRACT

BACKGROUND: Hypertension among persons with childbearing potential is on the rise. Maintaining proper blood pressure during pregnancy is vital to prevent maternal and neonatal complications. Yet, limited evidence on the risk-benefit of various antihypertensives presents challenges for informed decision-making during this critical period. This study aimed to examine the utilization patterns of different classes of antihypertensives among persons with pre-existing hypertension before, during, and after pregnancy. METHODS: We used MarketScan® Commercial Database 2011-2020 to analyze antihypertensive utilization among pregnant persons aged 12 to 55 identified via a validated algorithm. Pre-existing hypertension was defined as ≥1 inpatient or ≥2 outpatient encounters for hypertension within the 180 days preceding the LMP. Antihypertensive utilization was described during target periods: 0-3 months (0-3M) before pregnancy, 1st/2nd/3rd trimester (T1/2/3), 0-3M, and 4-6M after pregnancy. RESULTS: We identified 1,950,292 pregnancies, of which 20,576 (12,978 live and 7,598 non-live) had pre-existing hypertension. Both groups had similar antihypertensive use (80.1% and 81.0%, respectively) during the 6 months before pregnancy (baseline). For live-birth pregnancies, 13.9% of baseline users discontinued treatment during pregnancy, while 28.9% of non-users initiated antihypertensives during pregnancy, and 17.2% started postpartum. Before pregnancy, the predominant antihypertensives included thiazide diuretics (21.9%), combined α- and ß-blockers (18.4%), and dihydropyridines (16.2%). During pregnancy, thiazide diuretics, cardioselective ß-blockers, and ACE inhibitors declined (T3: 3.0%, 4.2%, and 0.8%). Dihydropyridine use was steady during pregnancy, but preference shifted from amlodipine to nifedipine in T3 (2.2.% vs.10.8%). Central α2-agonists increased during pregnancy (up to 15.2% in T3) compared to both pre- (9.8%) and post-pregnancy (5.7%). ARBs mirrored ACE inhibitors, with less than 1% utilization in later trimesters. Combination agents dropped from 10.8% pre-pregnancy to 0.8% in T3, then rebounded to 7.3% post-pregnancy. CONCLUSION: Research is warranted to evaluate the choice of antihypertensives and optimal timing to switch to safer alternatives, considering maternal and fetal outcomes.

ABSTRACT

ABSTRACT: Advanced pregnancy is associated with a higher risk of complicated aortopathies owing to the physiologic changes in pregnancy. The diagnosis can be elusive due to its rare incidence. The optimal treatment strategy is chosen based on the clinical condition of the patient, gestational age, and the severity of the aortic disease. A healthy young primigravida presented with acute chest pain in the early second trimester, diagnosed as a thoracic aortic aneurysm that had ruptured causing hemothorax. She underwent emergency endovascular repair under general anesthesia. Aortic disease should always be ruled out early in acute chest pain in pregnancy. Expeditious and strategic management helps improve maternal and fetal outcomes.

ABSTRACT

ABSTRACT: Pregnancy in a patient with pulmonary hypertension carries a high risk of mortality. It poses multiple problems in the management of pregnancy, labor, and postpartum, thereby emphasizing the need for a multidisciplinary team for a successful outcome. We describe the successful management of a case of Eisenmenger syndrome who developed pre-eclampsia during her 28 weeks of pregnancy. As far as our knowledge, this is the first case report that describes the use of milrinone in a parturient for a successful outcome.

ABSTRACT

BACKGROUND: Beta-blockers are commonly used drugs during pregnancy, especially in women with heart disease, and are regarded as relatively safe although evidence is sparse. Differences between beta-blockers are not well-studied. METHODS: In the Registry of Pregnancy And Cardiac disease (ROPAC, n = 5739), a prospective global registry of pregnancies in women with structural heart disease, perinatal outcomes (small for gestational age (SGA), birth weight, neonatal congenital heart disease (nCHD) and perinatal mortality) were compared between women with and without beta-blocker exposure, and between different beta-blockers. Multivariable regression analysis was used for the effect of beta-blockers on birth weight, SGA and nCHD (after adjustment for maternal and perinatal confounders). RESULTS: Beta-blockers were used in 875 (15.2%) ROPAC pregnancies, with metoprolol (n = 323, 37%) and bisoprolol (n = 261, 30%) being the most frequent. Women with beta-blocker exposure had more SGA infants (15.3% vs 9.3%, p < 0.001) and nCHD (4.7% vs 2.7%, p = 0.001). Perinatal mortality rates were not different (1.4% vs 1.9%, p = 0.272). The adjusted mean difference in birth weight was -177 g (-5.8%), the adjusted OR for SGA was 1.7 (95% CI 1.3-2.1) and for nCHD 2.3 (1.6-3.5). With metoprolol as reference, labetalol (0.2, 0.1-0.4) was the least likely to cause SGA, and atenolol (2.3, 1.1-4.9) the most. CONCLUSIONS: In women with heart disease an association was found between maternal beta-blocker use and perinatal outcomes. Labetalol seems to be associated with the lowest risk of developing SGA, while atenolol should be avoided.

ABSTRACT

BACKGROUND: Although peripartum cardiomyopathy (PPCM) is a fatal disease affecting young patients and fetuses, little is known about its recent prognosis and risk factors. This study investigated temporal trends in clinical characteristics and outcomes for PPCM in a nationwide multicenter registry. METHODS AND RESULTS: The study population comprised 340 patients (mean age, 33 years) who were diagnosed with PPCM between January 2000 and September 2022 in 26 tertiary hospitals in South Korea. PPCM was defined as heart failure with left ventricular ejection fraction ≤45% and no previously known cardiac disease. The main study outcomes included time to the first occurrence of all-cause death, heart transplantation, and cardiovascular hospitalization. The diagnosis of PPCM cases increased notably during the study period (P<0.001). However, clinical outcomes showed no significant improvement (all-cause death for 10 years: 0.9% [2000-2010] versus 2.3% [2011-2022], P=0.450; all-cause death and heart transplantation for 10 years: 3.6% [2000-2010] versus 3.0% [2011-2022] P=0.520; all-cause death, heart transplantation, and cardiovascular hospitalization for 10 years: 11.7% [2000-2010] versus 19.8% [2011-2022], P=0.240). High body mass index (hazard ratio [HR], 1.106 [95% CI, 1.024-1.196]; P=0.011), the presence of gestational diabetes (HR, 5.346 [95% CI, 1.778-16.07]; P=0.002), and increased baseline left ventricular end-diastolic dimension (HR, 1.078 [95% CI, 1.002-1.159]; P=0.044) were significant risk factors for poor prognosis. CONCLUSIONS: While the incidence of PPCM has increased over the past 20 years, the prognosis has not improved significantly. Timely management and close follow-up are necessary for high-risk patients with PPCM with high body mass index, gestational diabetes, or large left ventricular end-diastolic dimension.

ABSTRACT

BACKGROUND AND OBJECTIVES: Maternal stroke is a rare event with an increasing incidence. Data on the long-term prognosis after a maternal stroke are limited. We aimed to examine long-term mortality, recovery, vocational status and morbidity after a maternal stroke in a population-based setting including a comparison with matched, stroke-free controls. METHODS: In this register-based study with hospital chart validation, we included all women with a maternal stroke in Finland in 1987-2016 who survived the first year after the event. The recovery of the cases was assessed from the hospital charts by modified Rankin scale (mRS). Three controls matched by delivery year, age, and parity were selected for each case. All deaths until 2022 were identified from the Register for Causes of Death. Data on vocational status were obtained from Statistics Finland and morbidity from the Hospital Discharge Register and patient charts until year 2016. RESULTS: The study included 235 women with a maternal stroke and 694 matched controls. The median follow-up time was 17.5 years (interquartile range [IQR] 9.6-25.4) for mortality and 11.8 years (IQR 3.8-19.8) for vocational status and subsequent morbidity. Mortality among cases was 5.5% and among controls, 2.4% (age-adjusted odds ratio [OR] 2.3, 95% [CI] 1.1-4.9). At the end of the follow-up, 90.3% of the cases were independent in daily activities (mRS ≤2). In 2016, fewer women with a maternal stroke were working compared with controls (65.9% vs 79.1%, OR 0.5, 95% CI 0.4-0.7) and were more often receiving a pension (18.2% vs 4.9%, OR 4.4, 95% CI 2.7-7.3). Cerebrovascular events (age-adjusted OR 8.6 95% CI 4.4-17.1), cardiac diseases (age-adjusted OR 3.3, 95% CI 1.4-7.7), and major cardiovascular events were more common among cases during the follow-up (age-adjusted OR 7.6 95% CI 3.1-18.7). DISCUSSION: Despite having higher overall mortality and higher cardiovascular morbidity, the majority of the maternal stroke survivors recovered well. As expected, the vocational status of cases was inferior to that of controls, but most women were working at the end of the follow-up. Our study provides important information on the prognosis and sequalae after a maternal stroke to help in patient counseling and to improve secondary prevention.

ABSTRACT

Ventricular tachycardia (VT) is a rare but potentially fatal complication in pregnancy. We present a case of a pregnant woman with cardiomyopathy due to frequent premature ventricular complexes (PVCs) and VT originating from the left ventricular outflow tract. After presenting late in the third trimester, the decision was made to deliver the fetus after 4 days of medication titration due to continued sustained episodes of VT. After delivery, the patient continued to have frequent PVCs and VT several months after discharge, and she ultimately underwent a PVC ablation with dramatic reduction in PVC burden and improvement in cardiomyopathy. Multidisciplinary planning with a pregnancy heart team led to appropriate contingency planning and a successful delivery. This case highlights how multidisciplinary management is best practice in pregnancy complicated by VT and the need for better diagnostic guidelines for PVC-induced cardiomyopathy in the setting of pregnancy.

ABSTRACT

BACKGROUND: Perioperative management and cardiac surgery in pregnant women with anti-phospholipid syndrome combined with heart valve disease have been rarely reported. CASE PRESENTATION: We describe a case of transcatheter mitral valve-in-valve replacement in a pregnant woman with bioprosthetic valve failure and anti-phospholipid syndrome at 18 weeks' gestation. The patient underwent a cesarean section delivery at 34 weeks of gestation, resulting in the birth of a healthy baby. CONCLUSIONS: Transapical mitral valve-in-valve surgery resulted in safe maternal and infant outcomes in a pregnant woman with anti-phospholipid syndrome combined with mitral bioprosthetic valve failure. The success of this procedure underscored the importance of multidisciplinary teamwork.

ABSTRACT

BACKGROUND: Current guidelines recommend multidisciplinary cardiovascular obstetric programs (CVOB) to manage complex pregnant patients with cardiovascular disease. Minimal evaluation of these programs exists, with most of these programs offered at university-based centers. METHODS: A cohort of 113 patients managed by a CVOB team at a non-university health system (2018-2019) were compared to 338 patients seen by cardiology prior to the program (2016-2017). CVOB patients were matched with comparison patients (controls) on modified World Health Organization (mWHO) category classification, yielding a cohort of 102 CVOB and 102 controls. RESULTS: CVOB patients were more ethnically diverse and cardiovascular risk was higher compared to controls based on mWHO ≥ II-III (57% vs 17%) and. After matching, CVOB patients had more cardiology tests during pregnancy (median of 8 tests vs 5, p < .001) and were more likely to receive telemetry care (32% vs 19%, p = .025). The median number of perinatology visits was significantly higher in the CVOB group (8 vs 2, p < .001). Length of stay was a half day longer for vaginal delivery patients in the CVOB group (median 2.66 vs 2.13, p = .006). CONCLUSION: Implementation of a CVOB program resulted in a more diverse patient population than previously referred to cardiology. The CVOB program participants also experienced a higher level of care in terms of increased cardiovascular testing, monitoring, care from specialists, and appropriate use of medications during pregnancy.

ABSTRACT

OBJECTIVE: To estimate the association between mean arterial pressure during pregnancy and neonatal outcomes in participants with chronic hypertension using data from the CHAP (Chronic Hypertension and Pregnancy) trial. METHODS: A secondary analysis of the CHAP trial, an open-label, multicenter randomized trial of antihypertensive treatment in pregnancy, was conducted. The CHAP trial enrolled participants with mild chronic hypertension (blood pressure [BP] 140-159/90-104 mm Hg) and singleton pregnancies less than 23 weeks of gestation, randomizing them to active treatment (maintained on antihypertensive therapy with a goal BP below 140/90 mm Hg) or standard treatment (control; antihypertensives withheld unless BP reached 160 mm Hg systolic BP or higher or 105 mm Hg diastolic BP or higher). We used logistic regression to measure the strength of association between mean arterial pressure (average and highest across study visits) and to select neonatal outcomes. Unadjusted and adjusted odds ratios (per 1-unit increase in millimeters of mercury) of the primary neonatal composite outcome (bronchopulmonary dysplasia, retinopathy of prematurity, necrotizing enterocolitis, or intraventricular hemorrhage grade 3 or 4) and individual secondary outcomes (neonatal intensive care unit admission [NICU], low birth weight [LBW] below 2,500 g, and small for gestational age [SGA]) were calculated. RESULTS: A total of 2,284 participants were included: 1,155 active and 1,129 control. Adjusted models controlling for randomization group demonstrated that increasing average mean arterial pressure per millimeter of mercury was associated with an increase in each neonatal outcome examined except NEC, specifically neonatal composite (adjusted odds ratio [aOR] 1.12, 95% CI, 1.09-1.16), NICU admission (aOR 1.07, 95% CI, 1.06-1.08), LBW (aOR 1.12, 95% CI, 1.11-1.14), SGA below the fifth percentile (aOR 1.03, 95% CI, 1.01-1.06), and SGA below the 10th percentile (aOR 1.02, 95% CI, 1.01-1.04). Models using the highest mean arterial pressure as opposed to average mean arterial pressure also demonstrated consistent associations. CONCLUSION: Increasing mean arterial pressure was positively associated with most adverse neonatal outcomes except NEC. Given that the relationship between mean arterial pressure and adverse pregnancy outcomes may not be consistent at all mean arterial pressure levels, future work should attempt to further elucidate whether there is an absolute threshold or relative change in mean arterial pressure at which fetal benefits are optimized along with maternal benefits.

ABSTRACT

OBJECTIVE: To present a case of acute haemorrhagic stroke during 3rd trimester of pregnancy and to describe management and successful delivery of healthy baby. CASE REPORT: Haemorrhagic stroke is responsible for significant morbidity and mortality. Prognosis can be improved only by urgent diagnosis and care. We report a case of pregnant woman at 37th week of pregnancy with acute haemorrhagic stroke of unknown etiology with clinical appearance of thunderclap headaches and overall disorientation. We describe diagnostic approach and a successful management followed by further differential diagnosis and treatment. The foetus was delivered by acute caesarean section at 37th week of pregnancy. CONCLUSION: Occurrence of haemorrhagic stroke in pregnancy is rare. There are no specific guidelines that recommend the time and mode of delivery; therefore, each case is assessed individually.

ABSTRACT

Women with pulmonary hypertension (PH) have increased mortality during pregnancy and the peripartum period. An increasing number of publications suggest improvements in maternal outcomes, so we conducted a systematic review focusing on disease severity and maternal survival. After screening 9097 potential studies from 1967 to 2021, we identified 66 relevant publications. Outcomes improved continuously over time and mortality fell from 11.6% in studies published before 2015 to 8.2% in studies published after 2015. Mortality was lower in patients with mild disease (0.8%) than in those with Eisenmenger syndrome (26.2%) or idiopathic pulmonary arterial hypertension (7.4-24.0%). One major drawback of the published studies is that they define severity using echocardiographic-estimated pulmonary artery pressures, without considering more contemporary parameters. This systematic review provides new insights for preconception counseling on pregnancy risks related to PH and suggests that PH classification and severity should be carefully considered in determining an individual's pregnancy-associated risk.

ABSTRACT

BACKGROUND: The aim of this study was to evaluate the recovery rate of the left ventricular systolic function of women diagnosed with peripartum cardiomyopathy receiving specialized care in rural Tanzania. METHODS: In this observational study, women diagnosed with peripartum cardiomyopathy at a referral center in rural Tanzania between December 2015 and September 2021 were included. Women diagnosed between February and September 2021 were followed prospectively, those diagnosed between December 2015 and January 2021 were tracked back for a follow-up echocardiography. All participants received a clinical examination, a comprehensive echocardiogram, and a prescription of guideline-directed medical therapy. The primary outcome was recovery of the left ventricular systolic function (left ventricular ejection fraction > 50%). RESULTS: Median age of the 110 participants was 28.5 years (range 17-45). At enrolment, 49 (45%) participants were already on cardiac medication, 50 (45%) had severe eccentric hypertrophy of the left ventricle, and the median left ventricular ejection fraction was 30% (range 15-46). After a median follow-up of 8.98 months (IQR 5.72-29.37), 61 (55%) participants were still on cardiac medication. Full recovery of the left ventricular systolic function was diagnosed in 76 (69%, 95% CI 59.6-77.6%) participants. In the multivariate analysis, a higher left ventricular ejection fraction at baseline was positively associated with full recovery (each 5% increase; OR 1.7, 95% CI 1.10-2.62, p = 0.012), while higher age was inversely associated (each 10 years increase; OR 0.40, 95% CI 0.19-0.82, p = 0.012). CONCLUSION: Left ventricular systolic function recovered completely in 69% of study participants with peripartum cardiomyopathy from rural Tanzania under specialized care.

ABSTRACT

BACKGROUND AND OBJECTIVES: cardiovascular changes during pregnancy carry greater risk in heart disease. We analyze cardiovascular, obstetric and perinatal adverse effects associated with congenital and acquired heart disease during pregnancy and postpartum. MATERIALS AND METHODS: Cross-sectional and retrospective study, which included the 2017-2023 registry of pregnant or postpartum patients hospitalised with diagnosis of congenital or acquired heart disease. Adverse events (heart failure, stroke, acute pulmonary edema, maternal death, obstetric haemorrhage, prematurity and perinatal death) were compared with the clinical variables and the implemented treatment. RESULTS: 112 patients with a median age of 28 years (range 15-44) were included. Short circuits predominated 28 (25%). Thirty-six patients (32%) were classified in class IV of the modified WHO scale for maternal cardiovascular risk. Heart failure occurred in 39 (34.8%), acute lung edema 12 (10.7%), stroke 2 (1.8%), maternal death 5 (4.5%), obstetric haemorrhage 4 (3.6%), prematurity 50 (44.5%) and perinatal death 6 (5.4%). Shunts were associated with prematurity (adjusted odds ratio 4; 95% CI: 1.5-10, p = 0.006). Peripartum cardiomyopathy represented higher risk of pulmonary edema (adjusted OR 34; 95% CI: 6-194, p = 0.001) and heart failure (adjusted OR 16; 95% CI: 3-84, p = 0.001). An increased risk of obstetric haemorrhage was observed in patients with prosthetic valves (adjusted OR 30; 95% CI: 1.5-616, p = 0.025) and with the use of acetylsalicylic acid (adjusted OR 14; 95% CI: 1.2-16, p = 0.030). Furthermore, the latter was associated with perinatal death (adjusted OR 9; 95% CI: 1.4-68, p = 0.021). CONCLUSIONS: severe complications were found during pregnancy and postpartum in patients with heart disease, which is why preconception evaluation and close surveillance are vital.

ABSTRACT

Hypertensive disorders in pregnancy (HDP), remain the leading cause of adverse maternal, fetal, and neonatal outcomes. Epidemiological factors, comorbidities, assisted reproduction techniques, placental disorders, and genetic predisposition determine the burden of the disease. The pathophysiological substrate and the clinical presentation of HDP are multifarious. The latter and the lack of well designed clinical trials in the field explain the absence of consensus on disease management among relevant international societies. Thus, the usual clinical management of HDP is largely empirical. The current position statement of the Working Group 'Hypertension in Women' of the European Society of Hypertension (ESH) aims to employ the current evidence for the management of HDP, discuss the recommendations made in the 2023 ESH guidelines for the management of hypertension, and shed light on controversial issues in the field to stimulate future research.
