Sex and Racial Disparities in Proportionate Mortality of Premature Myocardial Infarction in the United States: 1999 to 2020.

BACKGROUND: The incidence of premature myocardial infarction (PMI) in women (<65 years and men <55 years) is increasing. We investigated proportionate mortality trends in PMI stratified by sex, race, and ethnicity. METHODS AND RESULTS: CDC WONDER (Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research) was queried to identify PMI deaths within the United States between 1999 and 2020, and trends in proportionate mortality of PMI were calculated using the Joinpoint regression analysis. We identified 3 017 826 acute myocardial infarction deaths, with 373 317 PMI deaths corresponding to proportionate mortality of 12.5% (men 12%, women 14%). On trend analysis, proportionate mortality of PMI increased from 10.5% in 1999 to 13.2% in 2020 (average annual percent change of 1.0 [0.8-1.2, P <0.01]) with a significant increase in women from 10% in 1999 to 17% in 2020 (average annual percent change of 2.4 [1.8-3.0, P <0.01]) and no significant change in men, 11% in 1999 to 10% in 2020 (average annual percent change of -0.2 [-0.7 to 0.3, P=0.4]). There was a significant increase in proportionate mortality in both Black and White populations, with no difference among American Indian/Alaska Native, Asian/Pacific Islander, or Hispanic people. American Indian/Alaska Natives had the highest PMI mortality with no significant change over time. CONCLUSIONS: Over the last 2 decades, there has been a significant increase in the proportionate mortality of PMI in women and the Black population, with persistently high PMI in American Indian/Alaska Natives, despite an overall downtrend in acute myocardial infarction-related mortality. Further research to determine the underlying cause of these differences in PMI mortality is required to improve the outcomes after acute myocardial infarction in these populations.

Equity and representation in cardiology research: A comprehensive analysis of authorship from low and low-middle income countries in cardiology journals.

Cardiovascular disease is the leading cause of mortality, disproportionately affecting low-income and low-middle-income countries (LICs/LMICs). Despite this, cardiology research commonly comes from affluent regions. This study assessed the authorship trends from LICs/LMICs in cardiology journals listed in PubMed from 2000 to 2022. The World Bank list was used to classify countries. The total number of articles published in the 138 cardiology journals was 529,359. The percentage of articles that included at least one author affiliated with LICs/LMICs institutions was 0.11 % and 2.23 %, respectively. Over the last decade, there has been an increase in the author's representation from LICs/LMICs; however, it is uneven, with some countries experiencing more significant increases (Zambia, Yemen, and Uganda for LICs, and India, Iran, and Lebanon for LMICs). Our findings highlight the inequity of research publication and invite our community to reflect on the need to develop strategies to improve representation from LICs/LMICs.

Socioeconomic Disparities in Women's Cardiovascular Health in the United States and Canada.

Cardiovascular disease has been the leading cause of death in the United States and Canada for decades. Although it affects millions of people across a multitude of backgrounds, notable disparities in cardiovascular health are observed among women and become more apparent when accounting for race and socioeconomic status. Although intrinsic sex-specific physiologic differences predispose women to poorer outcomes, social determinants of health (SDOH) and biases at both the individual provider and the larger health care system levels play an equal, if not greater, role. This review examines socioeconomic disparities in women compared with men regarding cardiovascular risk factors, treatments, and outcomes. Although various at-risk subpopulations exist, we highlight the impact of SDOH in specific populations, including patients with disabilities, transgender persons, and South Asian and Indigenous populations. These groups are underrepresented in studies and experience poorer health outcomes owing to structural barriers to care. These findings emphasise the significance of understanding the interplay of different socioeconomic factors and how their stacking can negatively affect women's cardiovascular health. To address these disparities, we propose a multipronged approach to augment culturally sensitive and patient-centred care. This includes increased cardiovascular workforce diversity, inclusion of underrepresented populations into analyses of cardiovascular metrics, and greater utilisation of technology and telemedicine to improve access to health care. Achieving this goal will necessitate active participation from patients, health care administrators, physicians, and policy makers, and is imperative in closing the cardiovascular health gap for women over the coming decades.

The Development of a Chest-Pain Protocol for Women Presenting to the Emergency Department.

Cardiovascular disease (CVD) is the leading cause of death in women worldwide, and of premature death in women in Canada. Despite improvements in cardiovascular care over the past 15-20 years, acute coronary syndrome (ACS) and CVD mortality continue to increase among women in Canada. Chest pain is a common symptom leading to emergency department visits for both men and women. However, women with ACS experience worse outcomes. compared with those of men, due to misdiagnosis or lack of diagnosis resulting in delayed care and underuse of guideline-directed medical therapies. CVD mortality rates are highest in Indigenous and racialized women and those with a disproportionately high number of adverse social determinants of health. CVD remains underrecognized, underdiagnosed, undertreated, and underresearched in women. Moreover, a lack of awareness of unique symptoms, clinical presentations, and sex-and-gender specific CVD risk factors, by healthcare professionals, leads to outcome disparities. In response to this knowledge gap, in acute recognition and management of chest-pain syndromes in women, the Canadian Women's Heart Health Alliance performed a needs assessment and review of CVD risk factors and ACS pathophysiology, through a sex and gender lens, and then developed a unique chest-pain assessment protocol utilizing modified dynamic programming algorithmic methodology. The resulting algorithmic protocol is presented. The output is intended as a quick reference algorithm that could be posted in emergency departments and other acute-care settings. Next steps include protocol implementation evaluation and impact assessment on CVD outcomes in women.

Les maladies cardiovasculaires (MCV) sont la principale cause de décès chez les femmes dans le monde et de décès prématuré chez les femmes au Canada. Malgré les progrès réalisés dans le domaine des soins cardiovasculaires au cours des 15 à 20 dernières années, les taux de syndrome coronarien aigu (SCA) et de mortalité due aux MCV continuent d'augmenter chez les femmes au Canada. La douleur thoracique est un symptôme fréquent qui pousse les hommes et les femmes à se rendre aux urgences. Toutefois, les femmes atteintes d'un SCA présentent de moins bons résultats cliniques que les hommes, en raison d'erreurs de diagnostic ou d'une absence de diagnostic causant des retards dans les soins prodigués et une sous-utilisation des traitements médicaux préconisés dans les lignes directrices. Les taux de mortalité liée aux MCV sont les plus élevés chez les femmes autochtones et les femmes racialisées ainsi que chez celles qui présentent un nombre particulièrement élevé de déterminants sociaux de la santé défavorables. Les MCV continuent d'être sous-estimées, sous-diagnostiquées et sous-traitées chez les femmes et ne sont pas suffisamment étudiées dans cette population. De plus, la méconnaissance par les professionnels de la santé des symptômes, des tableaux cliniques et des facteurs de risque de MCV selon le sexe et le genre entraînent des disparités dans les résultats cliniques. Pour combler ces lacunes dans les connaissances en matière de reconnaissance et de prise en charge des symptômes de douleur thoracique chez les femmes, l'Alliance canadienne de la santé cardiaque des femmes a réalisé une évaluation des besoins et un examen des facteurs de risque de MCV et de la physiopathologie du SCA en tenant compte des particularités liées au sexe et au genre, et a ensuite élaboré un protocole unique d'évaluation de la douleur thoracique faisant appel à une méthodologie algorithmique par programmation dynamique modifiée. Nous présentons le protocole algorithmique qui en est issu. Ce résultat se veut un algorithme de référence rapide pouvant être diffusé dans les services d'urgences et les autres services de soins de courte durée. Les prochaines étapes de notre travail seront d'évaluer la mise en œuvre du protocole et son incidence sur les issues cardiovasculaires chez les femmes.

This final chapter of the Canadian Women's Heart Health Alliance "ATLAS on the Epidemiology, Diagnosis, and Management of Cardiovascular Disease in Women" presents ATLAS highlights from the perspective of current status, challenges, and opportunities in cardiovascular care for women. We conclude with 12 specific recommendations for actionable next steps to further the existing progress that has been made in addressing these knowledge gaps by tackling the remaining outstanding disparities in women's cardiovascular care, with the goal to improve outcomes for women in Canada.

Dans ce chapitre final de l'ATLAS sur l'épidémiologie, le diagnostic et la prise en charge de la maladie cardiovasculaire chez les femmes de l'Alliance canadienne de santé cardiaque pour les femmes, nous présentons les points saillants de l'ATLAS au sujet de l'état actuel des soins cardiovasculaires offerts aux femmes, ainsi que des défis et des occasions dans ce domaine. Nous concluons par 12 recommandations concrètes sur les prochaines étapes à entreprendre pour donner suite aux progrès déjà réalisés afin de combler les lacunes dans les connaissances, en s'attaquant aux disparités qui subsistent dans les soins cardiovasculaires prodigués aux femmes, dans le but d'améliorer les résultats de santé des femmes au Canada.

The Canadian Women's Heart Health Alliance ATLAS on the Epidemiology, Diagnosis, and Management of Cardiovascular Disease in Women - Chapter 7: Sex, Gender, and the Social Determinants of Health.

Women vs men have major differences in terms of risk-factor profiles, social and environmental factors, clinical presentation, diagnosis, and treatment of cardiovascular disease. Women are more likely than men to experience health issues that are complex and multifactorial, often relating to disparities in access to care, risk-factor prevalence, sex-based biological differences, gender-related factors, and sociocultural factors. Furthermore, awareness of the intersectional nature and relationship of sociocultural determinants of health, including sex and gender factors, that influence access to care and health outcomes for women with cardiovascular disease remains elusive. This review summarizes literature that reports on under-recognized sex- and gender-related risk factors that intersect with psychosocial, economic, and cultural factors in the diagnosis, treatment, and outcomes of women's cardiovascular health.

Les profils de facteurs de risque, les facteurs sociaux et environnementaux, le tableau clinique, le diagnostic et le traitement des maladies cardiovasculaires montrent des différences importantes entre les femmes et les hommes. Il est plus probable que les femmes expérimentent des problèmes de santé complexes et multifactoriels, qui sont souvent en relation avec les disparités dans l'accès aux soins, la prévalence des facteurs de risque, les différences biologiques entre les sexes, les facteurs liés au genre et les facteurs socioculturels. De plus, la sensibilisation à la nature et à la relation intersectionnelles des déterminants socioculturels de santé, notamment les facteurs liés au sexe et au genre, qui influencent l'accès aux soins et les résultats cliniques des femmes atteintes d'une maladie cardiovasculaire demeure insaisissable. La présente revue résume la littérature qui porte sur les facteurs de risque liés au sexe et au genre peu reconnus qui se recoupent aux facteurs psychosociaux, économiques et culturels dans le diagnostic, le traitement et les résultats cliniques en lien avec la santé cardiovasculaire des femmes.

Closing the sex gap in cardiovascular mortality by achieving both horizontal and vertical equity.

Addressing sex differences and disparities in coronary heart disease (CHD) involves achieving both horizontal and vertical equity in healthcare. Horizontal equity in the context of CHD means that both men and women with comparable health statuses should have equal access to diagnosis, treatment, and management of CHD. To achieve this, it is crucial to promote awareness among the general public about the signs and symptoms of CHD in both sexes, so that both women and men may seek timely medical attention. Women often face inequity in the treatment of cardiovascular disease. Current guidelines do not differ based on sex, but their applications based on gender do differ. Vertical equity means tailoring healthcare to allow equitable care for all. Steps towards achieving this include developing treatment protocols and guidelines that consider the unique aspects of CHD in women. It also requires implementing guidelines equally, when there is not sex difference rather than inequities in application of guideline directed care.

Recent advances in cardiovascular risk assessment: The added value of non-invasive anatomic imaging.

In 2022, multiple original research studies were conducted highlighting the utility of coronary artery calcium (CAC) imaging in young individuals and provided further evidence for the role of CAC to improve atherosclerotic cardiovascular disease (ASCVD) risk assessment. Mean calcium density was shown to be a more reliable predictor than peak density in risk assessment. Additionally, in light of the ACC/AHA/Multispecialty Chest Pain Guideline's recent elevation of coronary computed tomography angiography (CCTA) to a Class I (level of evidence A) recommendation as an index diagnostic test for acute or stable chest pain, several studies support the utility of CCTA and guided future directions. This review summarizes recent studies that highlight the role of non-invasive imaging in enhancing ASCVD risk assessment across different populations.

Clinical Profiles, Outcomes, and Sex Differences of Patients With STEMI: Findings From the NORIN-STEMI Registry.

Background: Low- and middle-income countries account for most of the global burden of coronary artery disease. There is a paucity of data regarding epidemiology and outcomes for ST-segment elevation myocardial infarction (STEMI) patients in these regions. Objectives: The authors studied the contemporary characteristics, practice patterns, outcomes, and sex differences in patients with STEMI in India. Methods: NORIN-STEMI (North India ST-Segment Elevation Myocardial Infarction Registry) is an investigator-initiated prospective cohort study of patients presenting with STEMI at tertiary medical centers in North India. Results: Of 3,635 participants, 16% were female patients, one-third were <50 years of age, 53% had a history of smoking, 29% hypertension, and 24% diabetes. The median time from symptom onset to coronary angiography was 71 hours; the majority (93%) presented first to a non-percutaneous coronary intervention (PCI)-capable facility. Almost all received aspirin, statin, P2Y12 inhibitors, and heparin on presentation; 66% were treated with PCI (98% femoral access) and 13% received fibrinolytics. The left ventricular ejection fraction was <40% in 46% of patients. The 30-day and 1-year mortality rates were 9% and 11%, respectively. Compared with male patients, female patients were less likely to receive PCI (62% vs 73%; P < 0.0001) and had a more than 2-fold greater 1-year mortality (22% vs 9%; adjusted HR: 2.1; 95% CI: 1.7-2.7; P < 0.001). Conclusions: In this contemporary registry of patients with STEMI in India, female patients were less likely to receive PCI after STEMI and had a higher 1-year mortality compared with male patients. These findings have important public health implications, and further efforts are required to reduce these gaps.

Ischemia with No Obstructive Arteries (INOCA): A Review of the Prevalence, Diagnosis and Management.

Ischemia with no obstructive arteries (INOCA) is defined as patients with angiographic evidence of ischemia but no obstructive coronary artery disease (CAD) at coronary angiography. INOCA is estimated to be prevalent is 3-4 million individuals with a female predominance. INOCA is composed of different endotypes including: microvascular dysfunction, vasospasm and a combination of the 2. Diagnosis of INOCA requires either non-invasive or invasive techniques aimed at assessing coronary flow reserve (CFR), Index of Microcirculatory Resistance (IMR) and spasm secondary to acetylcholine injection. Although INOCA is associated with an increased risk of MACE and a decrease in quality of life, less than half of patients are appropriately treated. Treatment of INOCA remains elusive with current therapeutics tailored towards the specific endotype and ongoing clinical trials looking to assess the efficacy of traditional CAD medications.

Sex Differences in Acute Coronary Syndromes: A Global Perspective.

Despite increasing evidence and improvements in the care of acute coronary syndromes (ACS), sex disparities in presentation, comorbidities, access to care and invasive therapies remain, even in the most developed countries. Much of the currently available data are derived from more developed regions of the world, particularly Europe and the Americas. In contrast, in more resource-constrained settings, especially in Sub-Saharan Africa and some parts of Asia, more data are needed to identify the prevalence of sex disparities in ACS, as well as factors responsible for these disparities, particularly cultural, socioeconomic, educational and psychosocial. This review summarizes the available evidence of sex differences in ACS, including risk factors, pathophysiology and biases in care from a global perspective, with a focus on each of the six different World Health Organization (WHO) regions of the world. Regional trends and disparities, gaps in evidence and solutions to mitigate these disparities are also discussed.

Sex Differences in Management and Outcomes of Acute Myocardial Infarction Patients Presenting With Cardiogenic Shock.

OBJECTIVES: The aim of this study was to examine the sex differences in the risk profile, management, and outcomes among patients presenting with acute myocardial infarction cardiogenic shock (AMI-CS). BACKGROUND: Contemporary clinical data regarding sex differences in the management and outcomes of AMI patients presenting with CS are scarce. METHODS: Patients admitted with AMI-CS from the National Cardiovascular Data Registry Chest Pain-MI registry between October 2008 to December 2017 were included. Sex differences in baseline characteristics, in-hospital management, and outcomes were compared. Patients ≥65 years of age with available linkage data to Medicare claims were included in the analysis of 1-year outcomes. Multivariable logistic regression and Cox proportional hazards models adjusting for patient and hospital-related covariates were used to estimate sex-specific differences in in-hospital and 1-year outcomes, respectively. RESULTS: Among 17,195 patients presenting with AMI-CS, 37.3% were women. Women were older, had a higher prevalence of comorbidities, and had worse renal function at presentation. Women were less likely to receive guideline-directed medical therapies within 24 hours and at discharge, undergo diagnostic angiography (85.0% vs 91.1%), or receive mechanical circulatory support (25.4% vs 33.8%). Women had higher risks of in-hospital mortality (adjusted OR: 1.10; 95% CI: 1.02-1.19) and major bleeding (adjusted OR: 1.23; 95% CI: 1.12-1.34). For patients ≥65 years of age, women did not have a higher risk of all-cause mortality (adjusted HR: 0.98; 95% CI: 0.88-1.09) and mortality or heart failure hospitalization (adjusted HR: 1.01; 95% CI: 0.91-1.12) at 1 year compared with men. CONCLUSIONS: In this large nationwide analysis of patients with AMI-CS, women were less likely to receive guideline recommended care, including revascularization, and had worse in-hospital outcomes than men. At 1 year, there were no sex differences in the risk of mortality. Efforts are needed to address sex disparities in the initial care of AMI-CS patients.

Shared decision making and patient reported outcomes among adults with atherosclerotic cardiovascular disease, medical expenditure panel survey 2006-2015.

IMPORTANCE: Shared decision-making (SDM), one of the pillars of patient centered care is strongly encouraged and has been incorporated into the management of atherosclerotic cardiovascular disease (ASCVD) but the expansion of its use has been limited. OBJECTIVE: To determine the association of SDM on patient-reported health status, measures of quality of care, healthcare resource utilization, and healthcare spending among US adults with ASCVD. METHOD: This is a retrospective cohort study in an ambulatory setting, utilizing the Medical Expenditure Panel Survey (MEPS) 2006-2015. Analysis completed in December 2020. Participants included were adults 18 years and over with a diagnosis of ASCVD. We used the average weighted response to self-administered questionnaire evaluating shared-decision-making process as the exposure variable in the regression model. Outcome measures included inpatient hospitalizations, Emergency Department (ED) visits, statin and aspirin use, self-perception of health, and healthcare expenditure. RESULTS: When compared with individuals reporting poor SDM, those with optimal SDM were more likely to report statin and aspirin use [statin use, Odds Ratio (OR) 1.26 (95% CI, 1.09-1.46)], [aspirin use, 1.25 (1.07-1.45)], more likely to have a positive perception of their health and healthcare related quality of life, and were less likely to visit the ED [OR for ≥ 2 ED visits: 0.81 (0.67-0.99)]. There was no difference between groups in annual total or out of pocket healthcare expenditure. CONCLUSION: This study suggests that effective SDM is associated with better utilization of healthcare resources and patient reported health outcomes. We hope these results could provide useful evidence for expanding the use of SDM in patient-centered care among individuals with ASCVD.

Assessment of blood pressure skills and belief in clinical readings.

BACKGROUND: Accurate blood pressure (BP) measurement is essential for the diagnosis and management of hypertension. In clinical practice, BP is estimated using noninvasive methods with significant variability of application of guidelines in clinical practice, impacting the accuracy and certainty of BP measurements. OBJECTIVE: We sought to assess how BP is measured in clinical practice. METHODS: A survey was administered through professional societies that included predominantly cardiologists. Assessment of adherence to guideline recommendations for BP assessment was measured and compared to the level of confidence in clinic BP measurement. RESULTS: There were 571 surveys completed. The majority of respondents were cardiologists (61.1%), with 47 preventive cardiologists. BP was routinely checked in both arms by 53% at the initial visit, 48% check BP once each visit, and 64% wait 5 min before initial BP assessment. Automated BP assessment is used by 58% respondents. The majority (83%) trust their BP readings, and those who trust their BP readings are more likely to perform the initial BP assessment themselves, compared to those who do not trust the clinic BP readings (30.2% vs. 13.6%, P = 0.009). Accurate BP measurement is performed by 23% of cardiologists, and more likely performed accurately by a preventive cardiologist (38.3%) compared with other cardiologists (20.0%, P = 0.007). Accurate BP measurement is more likely for those who perform the initial BP themselves rather than any other staff (36.8% vs. 17.9%; P<0.001); and for those who repeat BP manually (80% vs. 54%; P<0.001), compared to those who do not measure BP accurately. Despite the inaccuracy of BP measurement, there is a high level of confidence in the BP readings. CONCLUSIONS: Accurate BP assessment continues to remain suboptimal in clinical practice. Reliability of BP assessment requires education, identifying barriers to implementation of recommendations and engagement of the entire team to improve BP assessment.

Agricultural policy and societal factors influence patients' ability to follow a healthy diet.

•Cardiovascular and cardiometabolic diseases are largely preventable, and are propagated by a poor diet.•Poor diet may be due to a lack of supply and access to healthy foods, agricultural subsidies, and marketing.•Improving national dietary intake starts with enhancing dietary guidelines, enacting legislative changes to optimize agricultural subsidies and food advertising, and incentivizing a plant-forward diet.

Optimizing the Potential for Telehealth in Cardiovascular Care (in the Era of COVID-19): Time Will Tell.

Before the coronavirus disease 2019 (COVID-19) pandemic, use of telehealth services had been limited in cardiovascular care. Potential benefits of telehealth include improved access to care, more efficient care management, reduced costs, the ability to assess patients within their homes while involving key caretakers in medical decisions, maintaining social distance, and increased patient satisfaction. Challenges include changes in payment models, issues with data security and privacy, potential depersonalization of the patient-clinician relationship, limitations in the use of digital health technologies, and the potential impact on disparities, including socioeconomic, gender, and age-related issues and access to technology and broadband. Implementation and expansion of telehealth from a policy and reimbursement practice standpoint are filled with difficult decisions, yet addressing these are critical to the future of health care.

Patient Education and Engagement through Social Media.

This review addresses the demographics of social media users and their relative health literacy. Means of overcoming health inequities via social media and the role of social media in patient education and engagement are explored. This review discusses forms of appropriate patient engagement, including the pitfalls of social media use.

Sex Differences in the Age of Diagnosis for Cardiovascular Disease and Its Risk Factors Among US Adults: Trends From 2008 to 2017, the Medical Expenditure Panel Survey.

Background Sex differences in the trends for control of cardiovascular disease (CVD) risk factors have been described, but temporal trends in the age at which CVD and its risk factors are diagnosed and sex-specific differences in these trends are unknown. Methods and Results We used the Medical Expenditure Panel Survey 2008 to 2017, a nationally representative sample of the US population. Individuals ≥18 years, with a diagnosis of hypercholesterolemia, hypertension, coronary heart disease, or stroke, and who reported the age when these conditions were diagnosed, were included. We included 100 709 participants (50.2% women), representing 91.9 million US adults with above conditions. For coronary heart disease and hypercholesterolemia, mean age at diagnosis was 1.06 and 0.92 years older for women, compared with men, respectively (both P<0.001). For stroke, mean age at diagnosis for women was 1.20 years younger than men (P<0.001). The mean age at diagnosis of CVD risk factors became younger over time, with steeper declines among women (annual decrease, hypercholesterolemia [women, 0.31 years; men 0.24 years] and hypertension [women, 0.23 years; men, 0.20 years]; P<0.001). Coronary heart disease was not statistically significant. For stroke, while age at diagnosis decreased by 0.19 years annually for women (P=0.03), it increased by 0.22 years for men (P=0.02). Conclusions The trend in decreasing age at diagnosis for CVD and its risk factors in the United States appears to be more pronounced among women. While earlier identification of CVD risk factors may provide opportunity to initiate preventive treatment, younger age at diagnosis of CVD highlights the need for the prevention of CVD earlier in life, and sex-specific interventions may be needed.

Temporal Changes in Hypertensive Disorders of Pregnancy and Impact on Cardiovascular and Obstetric Outcomes.

Hypertensive disorders of pregnancy (HDP) are a major cause of maternal morbidity. However, short-term outcomes of HDP subgroups remain unknown. Using National Inpatient Sample database, all delivery hospitalizations between 2004 and 2014 with or without HDP (preeclampsia/eclampsia, chronic hypertension, superimposed preeclampsia on chronic hypertension, and gestational hypertension) were analyzed to examine the association between HDP and adverse in-hospital outcomes. We identified >44 million delivery hospitalizations, within which the prevalence of HDP increased from 8% to 11% over a decade with increasing comorbidity burden. Women with chronic hypertension have higher risks of myocardial infarction, peripartum cardiomyopathy, arrhythmia, and stillbirth compared to women with preeclampsia. Out of all HDP subgroups, the superimposed preeclampsia population had the highest risk of stroke (odds ratio [OR] 7.83, 95% confidence interval [CI] 6.25 to 9.80), myocardial infarction (OR 5.20, 95% CI 3.11 to 8.69), peripartum cardiomyopathy (OR 4.37, 95% CI 3.64 to 5.26), preterm birth (OR 4.65, 95% CI 4.48 to 4.83), placental abruption (OR 2.22, 95% CI 2.09 to 2.36), and stillbirth (OR 1.78, 95% CI 1.66 to 1.92) compared to women without HDP. In conclusion, we are the first to evaluate chronic systemic hypertension without superimposed preeclampsia as a distinct subgroup in HDP and show that women with chronic systemic hypertension are at even higher risk of some adverse outcomes compared to women with preeclampsia. In conclusion, the chronic hypertension population, with and without superimposed preeclampsia, is a particularly high-risk group and may benefit from increased antenatal surveillance and the use of a prognostic risk assessment model incorporating HDP to stratify intrapartum care.
