Abstract
OBJECTIVE Transient ischemic attack (TIA) is rare in women of reproductive age. We aimed to compare perinatal outcomes between women who suffered from a TIA to those who did not. METHODS A retrospective population-based cohort study utilizing the Healthcare Cost and Utilization Project, Nationwide Inpatient Sample (HCUP-NIS). All women who delivered or had a maternal death in the US (2004-2014) were included in the study. Pregnancy, delivery, and neonatal outcomes were compared between women with an ICD-9 diagnosis of a TIA to those without. RESULTS Overall, 9 096 788 women met the inclusion criteria. Of these, 203 women (2.2/100000) had a TIA (either before or during pregnancy). Women with TIA, compared to those without, were more likely to be older than 35 years of age, white, in the highest income quartile, be insured by private insurance and suffer from obesity and chronic hypertension. Patients in the TIA group, compared to those without, had a higher rate of pregnancy-induced hypertension (aOR 2.5, 95% CI: 1.55-4.05, P < 0.001), pre-eclampsia (aOR 3.77, 95% CI: 2.15-6.62, P < 0.001), eclampsia (aOR 28.05, 95% CI: 6.91-113.95, P < 0.001), preterm delivery (aOR 1.78, 95% CI: 1.03-3.07, P = 0.039), and maternal complications such as deep vein thrombosis (aOR 33.3, 95% CI: 8.07-137.42, P < 0.001). Regarding neonatal outcomes, patients with a TIA, compared to those without, had a higher rate of congenital anomalies (aOR 7.04, 95% CI: 2.86-17.32, P < 0.001). CONCLUSION Women with a TIA diagnosis before or during pregnancy had a higher rate of maternal complications, including hypertensive disorders of pregnancy and venous thromboembolism, as well as an increased risk of congenital anomalies.

Abstract
Objective Cerebrovascular accidents (CVA) in childbearing-age women are rare. We aimed to evaluate the association between CVA events prior to delivery and obstetrical and neonatal outcomes. Methods A retrospective cohort study was conducted using data from the Healthcare Cost and Utilization Project, Nationwide Inpatient Sample (HCUP-NIS) database. All pregnant women who delivered or had a maternal death in the US from 2004 to 2014 were included in the study. We performed a comparison between women with an ICD-9 diagnosis of CVA before the delivery admission and those without. Obstetrical and neonatal outcomes were compared between the two groups. Results In total, 9,096,788 women fulfilled the inclusion criteria. Among them, 695 women (7.6 per 100,000) were diagnosed with a CVA before delivery. Women with a history of CVA, compared to those without, were more likely to be Black, older than 35 years of age, and suffer from obesity, chronic hypertension, pregestational diabetes, and thyroid disease. Patients with a prior CVA, compared to those without, had higher rates of pregnancy-induced hypertension (aOR 6.41, 95% CI 5.03-8.39, p < 0.001), preeclampsia (aOR 7.65, 95% CI 6.03-9.71, p < 0.001), and eclampsia (aOR 171.56, 95% CI 124.63-236.15, p < 0.001). Additionally, they had higher rates of preterm delivery (aOR 1.72, 95% CI 1.33-2.22,p = 0.003), cesarean section (aOR 2.69, 95% CI 2.15-3.37, p < 0.001), and maternal complications such as a peripartum hysterectomy (aOR 11.62, 95% CI 5.77-23.41, p < 0.001), postpartum hemorrhage (aOR 3.39, 95 % CI 2.52-4.54, p < 0.001), disseminated intravascular coagulation (aOR 16.32, 95% CI 11.33-23.52, p < 0.001), venous thromboembolism (aOR 45.08, 95% CI 27.17-74.8, p < 0.001), and maternal death (aOR 486.11, 95% CI 307.26-769.07, p < 0.001). Regarding neonatal outcomes, patients with a prior CVA, compared to those without, had a higher rate of intrauterine fetal demise and congenital anomalies. Conclusion Women with a CVA event before delivery have a significantly higher incidence of maternal complications, including hypertensive disorders of pregnancy, and neonatal complications, such as intrauterine fetal demise and congenital anomalies. Rates of maternal death were dramatically increased, and this association requires further evaluation.

Abstract
OBJECTIVE To estimate temporal trends of stroke in the peripartum period and to assess the relationship between stroke and maternal adverse outcomes vis-à-vis timing and hypertension. METHODS We conducted a retrospective, cross-sectional study using the National Inpatient Sample to identify hospitalizations with pregnancy-associated stroke in the United States (2016-2019). Temporal trends in pregnancy-associated stroke were examined according to timing of stroke (antepartum vs postpartum) and both prepregnancy and pregnancy hypertensive disorders (yes vs no). Multivariable Poisson regression models with robust error variance were used to examine the association among maternal adverse outcomes, timing of stroke, and hypertensive disorders. RESULTS Among 15,977,644 pregnancy hospitalizations, 6,100 hospitalizations (38.2/100,000 hospitalizations) were with pregnancy-associated stroke. Of these, 3,635 (59.6%) had antepartum pregnancy-associated stroke and 2,465 (40.4%) had postpartum pregnancy-associated stroke; alternatively, 2,640 (43.3%) had hypertensive disorders, and 3,460 (56.7%) were without hypertensive disorders. From 2016 to 2019, the overall rate of pregnancy-associated stroke (37.5 to 40.8/100,000 pregnancy hospitalizations, P=.028), rate of postpartum pregnancy-associated stroke (14.6 to 17.6/100,000 pregnancy hospitalizations, P=.005), and rate of pregnancy-associated stroke with hypertensive disorders (14.9 to 17.2/100,000 pregnancy hospitalizations, P=.013) increased. Antepartum pregnancy-associated stroke and pregnancy-associated stroke without hypertensive disorders, however, remained stable. Despite higher risk of maternal morbidity in postpartum stroke hospitalizations, including mechanical ventilation and pneumonia, there was no significant difference in in-hospital mortality between antepartum and postpartum stroke. Similarly, between pregnancy-associated stroke with hypertensive disorders and stroke without hypertensive disorders, an increased risk of mechanical ventilation, seizure, and prolonged hospital stay was seen for stroke with hypertensive disorders without an increase in mortality. CONCLUSION A nationally representative sample of hospitalizations in the United States indicates an increasing trend in the rate of postpartum stroke. Almost half of hospitalizations with pregnancy-associated stroke have concomitant hypertensive disorders. Risk of adverse outcomes, but not mortality, is elevated in patients with stroke occurring in the postpartum period and stroke associated with hypertensive disorders.

Abstract
Globally, patients living with sickle cell disease are now surviving to reproductive age, with life expectancy approaching 50 years in most countries. Thus, reproductive options are now essential for patients living with the condition. However, it can be associated with maternal, delivery, and fetal complications. Outcomes may vary depending on the level of expertise and resources. In this piece we provide an optional guideline for managing sickle cell disease in pregnancy. The therapeutic option of serial exchange prophylactic transfusion has been offered in the context of a clinical trial (TAPS2).

Abstract
Purpose of Review The "fourth trimester" concept, defined as the first 12 weeks after delivery (and beyond), is a critical window of time for clinicians to intervene to optimize women's cardiovascular health after pregnancy. A timely and comprehensive postpartum cardiovascular assessment should be performed in all women following delivery in order to (1) follow up medical conditions present prior to conception, (2) evaluate symptoms and signs of common postpartum complications, and (3) identify risk factors and prevent future adverse cardiovascular outcomes. In this review, we aim to discuss major maternal cardiovascular risk factors such as hypertensive disorders of pregnancy, gestational diabetes mellitus, postpartum weight retention, and postpartum depression, as well as lactation as a potential protective risk modifying factor. Additionally, we will review effectiveness of outpatient interventions to enhance transitions in cardiovascular care during the fourth trimester. Recent Findings A seamless hand-off from obstetric to primary care, and potentially cardiology, is needed for early detection and management of hypertension, weight, glycemic control, stress and mood, and long-term cardiovascular risk. Additionally, the use of telemedicine, blood pressure self-monitoring, remote activity monitoring, and behavioral health coaches are potentially feasible modalities to augment clinic-based care for cardiovascular risk factors and weight management, but additional studies are needed to study their long-term effectiveness. Summary Development of a comprehensive postpartum care plan with careful consideration of each patient's risk profile and access to resources is critical to improve maternal morbidity and mortality, reduce health disparities, and achieve long-term cardiovascular health for women. Supporting postpartum well-being of women during this transition period requires a multidisciplinary approach, especially primary care engagement, and planning should start before delivery.

Abstract
Pregnancy-related cardiovascular disease with stroke remains a considerable source of higher maternal morbidity and mortality occurs in periods of pregnancy, delivery, and postpartum. It is essential to counsel the mother before pregnancy by an expert cardiologist and obstetric team to discuss any event related to preexistent cardiac or past preeclampsia for estimation of maternal and fetal risks. In pregnancy, the cardiac state includes hypertensive disorders, ischemic heart disease, valvular disease, and postpartum stroke. The incidence of stroke is increasing in pregnancy, particularly in postpartum, and its strong relationship with hypertensive disorders of pregnancy (preeclampsia). The combined cardiologist and obstetrics team requires during pregnancy mainly due to the approach to the management of a cardiac disease that subsequently prevents stroke postpartum. Therefore, a general perception of cardiac disease during pregnancy, delivery, and postpartum should be a core knowledge extent for all cardiovascular and clinicians. Many studies provided linked that deregulation of microRNAs (miRNAs) in maternal circulation and placenta tissue may development of pregnancy complications including preeclampsia considered a diagnostic marker. The desire of this review provides a detailed outline of current knowledge and dealing in this field with strength on the physiological changes during pregnancy.

Abstract
Importance The maternal risk of strokes in the United States is approximately 30/100,000 pregnancies, and strokes are the eighth leading cause of maternal death. Because of the relationship between stroke and significant neurological disability/maternal death, obstetrical health care providers must be able to identify, evaluate, diagnosis, and treat these women. Evidence Acquisition PubMed was searched using the search terms "stroke" OR "cerebrovascular accident" OR "intracranial hemorrhage" AND "pregnancy complications" OR "risk factors" OR "management" OR "outcome." The search was limited to the English language and was restricted to articles from 2000 to 2020. Results There were 319 abstracts identified, and 90 of the articles were ultimately used as the basis of this review. Presenting stroke signs and symptoms include headache, composite neurologic defects, seizures, and/or visual changes. Diagnosis is typically made with computed tomography scan using abdominal shielding or magnetic resonance imaging without contrast. Management options for an ischemic stroke include reperfusion therapy with intravenous recombinant tissue plasminogen activator catheter-based thrombolysis and/or mechanical thrombectomy. Hemorrhagic strokes are treated similarly to strokes outside of pregnancy, and that treatment is based on the severity and location of the hemorrhage. Conclusions and Relevance Early recognition and management are integral in decreasing the morbidity and mortality associated with a stroke in pregnancy. Relevance Statement This study was an evidence-based review of stroke in pregnancy and how to diagnose and mange a pregnancy complicated by a stroke.

Abstract
Women face a disproportionate burden of stroke mortality and disability. Biologic sex and sociocultural gender both contribute to differences in stroke risk factors, assessment, treatment, and outcomes. There are substantial differences in the strength of association of stroke risk factors, as well as female-specific risk factors. Moreover, there are differences in presentation, response to treatment, and stroke outcomes in women. This review outlines current knowledge of impact of sex and gender on stroke, as well as delineates research gaps and areas for future inquiry.

Abstract
Cardiovascular (CV) risk factors are rising among women of reproductive age. Obesity, hyperlipidaemia, diabetes, and hypertension are associated with adverse pregnancy outcomes and increased CV disease (CVD) risk following pregnancy. Pre-conception counselling and longitudinal postpartum follow-up with ongoing CV risk factor screening are critical for early CVD prevention, though significant racial/ethnic disparities in access to care result in significant gaps. This review summarises the recommended management of CV risk factors during and after pregnancy. For obesity, prevention of excessive weight gain is critical. Except in rare cases, lipid-lowering therapies for women with hyperlipidaemia should be stopped before pregnancy. Women with diabetes in pregnancy should maintain tight glucose control, with hemolgobin A1c (HbA1c) <6.5% to prevent congenital abnormalities. Hypertensive disorders of pregnancy are associated with high maternal and neonatal morbidity and require long-term follow-up to prevent future CVD. Finally, this review highlights the lack of clinical trials informing optimal treatment strategies of CV risk factors during and after pregnancy. Further research is needed to better understand how to improve long-term CV health among this high-risk population.

Abstract
Pregnancy confers a substantially increased risk of stroke, especially during the third trimester and until 6 weeks postpartum. Hypertensive disorders of pregnancy and gestational hypercoagulability are important contributors to obstetric stroke. Preeclampsia and eclampsia confer risk for future cardiovascular disease. Hemorrhagic stroke is the most common type of obstetric stroke. Ischemic stroke can result from cardiomyopathy, paradoxical embolism, posterior reversible encephalopathy, reversible cerebral vasoconstriction syndrome, and dissections. Cerebral venous sinus thrombosis is a frequent complication of pregnancy.

Abstract
The risk of postpartum (PP) stroke is increased in complicated pregnancies. Deficiency in CD4 T cell subsets is associated with preeclampsia and may contribute to PP vascular disease, including internal carotid artery (ICA) stenosis and stroke. We hypothesized that CD4 T cell deficiency in pregnancy would result in ICA dysregulation, including enhanced ICA vasoconstriction. We characterized the function, mechanical behavior, and structure of ICAs from C57BL/6 (WT) and CD4 deficient (CD4KO) mice, and assessed the role of NO in the control of ICA function at pre-conception and PP. WT and CD4KO mice were housed under pathogen-free conditions, mated to same-strain males, and allowed to litter or left virgin. At 3 days or 4 weeks PP, mice were euthanized. The responses to phenylephrine (PE), high K+ and acetylcholine (ACh) were assessed in pressurized ICAs before and after NOS inhibition. Passive lumen diameters were measured at 3–140 mmHg. eNOS and iNOS expression as well as the presence of T cells were evaluated by immunohistochemistry. Constriction of WT ICAs to PE was not modified PP. In contrast, responses to PE were significantly increased in ICAs from PP as compared to virgin CD4KO mice. Constriction to high K+ was not enhanced PP. ICAs from WT and CD4KO mice were equally sensitive to ACh with a significant rightward shift of dose-response curves after L-NNA treatment. NOS inhibition enhanced PE constriction of ICAs from WT virgin and PP mice. Although a similar effect was detected in ICAs of virgin CD4KO mice, no such changes were observed in vessels from PP CD4KO mice. Passive arterial distensibility at physiological levels of pressure was not modified at PP. ICA diameters were significantly increased in PP with no change in vascular wall thickness. Comparison of eNOS expression in virgin, 3 days and 4 weeks PP revealed a reduced expression in ICA from CD4 KO vs. WT PP vessels which reached significance at 4 weeks PP. iNos expression was similar and decreased over the PP period in vessels from WT and CD4KO mice. Dysregulation of the CD4 T cell population in pregnancy may make ICA vulnerable to vasospasm due to decreased NO-dependent control of ICA constriction. This may lead to cerebral hypoperfusion and increase the risk of maternal PP stroke.

Abstract
Introduction Hypertensive disorders frequently complicate pregnancy and contribute substantially to maternal and perinatal morbidity and mortality. Identification of risk factors for hypertensive disorders of pregnancy (HDP) can help determine the particular patient group which requires appropriate intervention. Methods This prospective cross-sectional hospital-based study conducted from January 2016 to January 2019 included all pregnant women beyond 20 weeks of gestation complicated by HDP. The objectives were to determine the incidence of HDP and associated maternal and perinatal mortality and morbidity rates along with factors influencing it. Data collected were entered in Microsoft Excel (Microsoft Corporation, Redmond, WA) and analyzed with the Statistical Package for the Social Sciences (SPSS) software version 21 (IBM Corp. Armonk, NY). Results In our study, out of 5460 deliveries, 402 (7.4%) cases had HDP, 27.6% had gestational hypertension, 27.6% had mild preeclampsia, 33.6% had severe preeclampsia, and 11.2% had eclampsia. Fifty-four (13.4%) cases required admission in the intensive care unit and 12 (2.9%) ended in maternal deaths. The cause of maternal mortality was cerebral hemorrhage in eight (66.6%) cases and pulmonary edema in four (33.3%) cases. All maternal deaths occurred in women with severe preeclampsia and eclampsia and eclampsia was significantly higher. Maternal deaths were more when systolic blood pressure (SBP) was ≥ 160mmHg, diastolic blood pressure (DBP) was ≥ 110mmHg, significantly more with 3+ proteinuria, but no association was found with age, parity, booking status, socio-economic status, gestational age, or mode of delivery. All mothers with HDP received treatment with antihypertensives. There were 60 (14.9%) cases of perinatal mortality. Perinatal deaths were more in unbooked cases and preterm HDP, significantly more with SBP ≥160 mmHg, DBP ≥110 mmHg and ≥2+proteinuria, but no association was found with parity or mode of delivery. Besides mortality, there was a significant burden of maternal and perinatal morbidity, which was more in women with severe preeclampsia and eclampsia. Conclusion Routine antenatal screening for HDP in all pregnant women with appropriate and timely interventions in women at risk may help reduce HDP-related maternal and perinatal morbidity and mortality.

Abstract
Stroke in pregnancy is rare and has a wide range of etiologies and implications on stroke management that differ from nonpregnant individuals. The highest risk of stroke is during the third trimester and puerperium period, where hypertensive disorders of pregnancy occur; however, stroke can occur at any point during pregnancy. In this chapter, we will provide an overview of the epidemiology of stroke in pregnancy and then review the specific etiologies of ischemic and hemorrhagic stroke as they relate to pregnant women. Finally, we discuss the process of acute stroke evaluation in pregnancy and the management of women after stroke with regard to long-term risk factors, medications, and implications in future pregnancies. Throughout the chapter, we highlight relevant guidelines from the American Heart Association and American Stroke Association and key literature on stroke in pregnancy.

Abstract
Background Stroke is a serious complication of hypertensive disorders of pregnancy (HDP), with potentially severe and long‐term sequelae. However, the temporal trends, predictors, and outcomes of stroke in women with HDP at delivery remain unknown. Methods and Results All HDP delivery hospitalizations with or without stroke event (ischemic, hemorrhagic, or unspecified) between 2004 and 2014 in the United States National Inpatient Sample were analyzed to examine incidence, predictors, and prognostic impact of stroke. Of 4 240 284 HDP delivery hospitalizations, 3391 (0.08%) women had stroke. While the prevalence of HDP increased over time, incident stroke rates decreased from 10 to 6 per 10 000 HDP delivery hospitalizations between 2004 and 2014. Women with stroke were increasingly multimorbid, with some risk factors being more strongly associated with ischemic strokes, including congenital heart disease, peripheral vascular disease, dyslipidemia, and sickle cell disease. Delivery complications were also associated with stroke, including cesarean section (odds ratio [OR], 1.58; 95% CI, 1.33–1.86), postpartum hemorrhage (OR, 1.91; 95% CI, 1.33–1.86), and maternal mortality (OR, 99.78; 95% CI, 59.15–168.31), independently of potential confounders. Women with stroke had longer hospital stays (median, 6 versus 3 days), higher hospital charges (median, $14 655 versus $4762), and a higher proportion of nonroutine discharge locations (38% versus 4%). Conclusions The incidence of stroke in women with HDP has declined over time. While a relatively rare event, identification of women at highest risk of ischemic or hemorrhagic stroke on admission for delivery is important to reduce long‐term sequelae.
