Cardiovascular Disease in Women: Clinical Perspectives

Maternal Microvascular Dysfunction During and After Preeclamptic Pregnancy

Preeclampsia, a pregnancy disorder characterized by de novo hypertension and maternal multisystem organ dysfunction, is the leading cause of maternal mortality worldwide and is associated with a fourfold greater risk of cardiovascular disease throughout the lifespan. Current understanding of the etiology of preeclampsia remains unclear, due in part to the varying phenotypical presentations of the disease, which has hindered the development of effective and mechanism-specific treatment or prevention strategies both during and after the affected pregnancy. These maternal sequelae of preeclampsia are symptoms of systemic vascular dysfunction in the maternal nonreproductive microvascular beds that drives the development and progression of adverse cardiovascular outcomes during preeclampsia. Despite normalization of vascular disturbances after delivery, subclinical dysfunction persists in the nonreproductive microvascular beds, contributing to an increased lifetime risk of cardiovascular and metabolic diseases and all-cause mortality. Given that women with a history of preeclampsia demonstrate vascular dysfunction despite an absence of traditional CVD risk factors, an understanding of the underlying mechanisms of microvascular dysfunction during and after preeclampsia is essential to identify potential therapeutic avenues to mitigate or reverse the development of overt disease. This article aims to provide a summary of the existing literature on the pathophysiology of maternal microvascular dysfunction during preeclampsia, the mechanisms underlying the residual dysfunction that remains after delivery, and current and potential treatments both during and after the affected pregnancy that may reduce microvascular dysfunction in these high-risk women. © 2024 American Physiological Society.

Psychological interventions targeting mental health and stress among females with cardiac disease: a scoping review

Interventions that target mental health symptoms and stress among those with established cardiac disease have included predominately male samples despite female patients reporting greater severity of these symptoms. The aim of this scoping review was to synthesize the published literature on psychological interventions for females with cardiac disease. We conducted a systematic search of peer-reviewed randomized clinical trials (RCTs) published in the English language from 2003 to 2023, in three databases: Medline (Ovid), PsycInfo (Ovid), and CINAHL (EBSCO). Articles that included female samples, a control or comparison group, implemented psychological interventions, and measured depression, anxiety, or stress as an outcome were included in the review. Nine articles describing eight RCTs of psychological interventions, with a total of 1587 female patients with cardiac disease, were included. Interventions were most successful at reducing stress (75% of studies measuring stress reported efficacy), while symptoms of depression and anxiety were less responsive to intervention (∼30% of studies targeting these symptoms reported improvements) in comparison to a control condition. This scoping review highlights that further advancement in knowledge is required to better address the needs of females with cardiac disease and distress, particularly depression and anxiety.

Oral hormonal contraceptives and cardiovascular risks in females

Oral hormonal contraception (OHC) is a widely employed method in females for the prevention of unintended pregnancies, as well as for the treatment of menstrual disorders, endometriosis, and polycystic ovarian syndrome. However, it is believed that with OHCs use, some females may have higher risk of cardiovascular diseases, such as hypertension, diabetes, myocardial infarction, thrombosis, and heart failure. Although such risks are infrequently detected in healthy young females with the use of oral contraceptives, slightly elevated risks of cardiovascular diseases have been observed among reproductive-aged healthy females. However, prolonged use of OHC has also been claimed to have protective cardiac effects and may contribute to reduced risk of cardiovascular disease. In fact, the debate on whether OHC administration increases the risk of cardiovascular diseases has been ongoing with inconsistent and controversial viewpoints. Nevertheless, a great deal of work has been carried out to understand the relationship between OHC use and the occurrence of cardiovascular risk in females who use OHC for preventing the unwanted pregnancy or treatment of other disorders. Therefore, in this review we summarize the most recent available evidence regarding the association between the use of oral hormonal contraceptives and the risk for cardiovascular disease in females who are using OHC to prevent unintended pregnancy.

Anti-dyslipidemic effects of Pueraria lobata root and Glycine max (L.) Merrill extracts fermented with Lactiplantibacillus plantarum in ovariectomized mice

Pueraria lobata root and Glycine max (L.) Merrill are rich in phytoestrogens. However, these bioactive ingredients have limited bioavailability due to their high molecular weight. In this study, we extracted two natural products and fermented with Lactiplantibacillus plantarum before mixing the fermented extracts (FPE-FGE). To understand whether FPE-FGE could alleviate menopause with dyslipidemia, we examined their effects on ovariectomy (OVX)-induced dyslipidemia in mice. Oral administration of the FPE-FGE (1:9, 3:7, and 9:1) did not affect safety-related biomarkers, such as uterus index (%), vagina index (%), aspartate aminotransferase, alanine aminotransferase, blood urea nitrogen, and creatinine. Furthermore, FPE-FGE (1:9, 3:7, and 9:1) increased the levels of 17β-estradiol (E2) and expression of uterus estrogen receptor β (ERβ); there was little effect on the expression of uterus estrogen receptor α (ERα), and reduced the levels of gonadotropins, such as luteinizing hormone (LH) and follicle-stimulating hormone (FSH). However, only the FPE-FGE (3:7) reduced the levels of blood lipids, including total cholesterol (TC) and LDL-cholesterol (LDL-C). Accordingly, FPE-FGE (3:7) upregulated endothelial nitric oxide synthase (eNOS), nitric oxide (NO), cyclic guanosine monophosphate (cGMP), and protein kinase G (PKG). In conclusion, FPE-FGE (3:7) attenuated the menopausal dyslipidemia by upregulating eNOS-NO-cGMP signaling pathway.

Multimodal deep learning models utilizing chest X-ray and electronic health record data for predictive screening of acute heart failure in emergency department

BACKGROUND AND OBJECTIVES

Ambiguity in diagnosing acute heart failure (AHF) leads to inappropriate treatment and potential side effects of rescue medications. To address this issue, this study aimed to use multimodality deep learning models combining chest X-ray (CXR) and electronic health record (EHR) data to screen patients with abnormal N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels in emergency departments.

METHODS

Using the open-source dataset MIMIC-IV and MIMICCXR, the study population consisted of 1,432 patients and 1,833 pairs of CXRs and EHRs. We processed the CXRs, extracted relevant features through lung-heart masks, and combined these with the vital signs at triage to predict corresponding NT-proBNP levels.

RESULTS

The proposed method achieved a 0.89 area under the receiver operating characteristic curve by fusing predictions from single-modality models of heart size ratio, radiomic features, CXR, and the region of interest in the CXR. The model can accurately predict dyspneic patients with abnormal NT-proBNP concentrations, allowing physicians to reduce the risks associated with inappropriate treatment.

CONCLUSION

The study provided new image features related to AHF and offered insights into future research directions. Overall, these models have great potential to improve patient outcomes and reduce risks in emergency departments.

Prevalence of Cardiometabolic Risk Factors in Women: Insights From the Houston HeartReach Study

BACKGROUND

Cardiovascular disease is the leading cause of death among women in the United States. Past research has highlighted the importance of the relationship between female-specific demographics and traditional risk factors. The present analysis aimed to identify the prevalence of modifiable risk factors in women attending a community cardiovascular health screening.

METHODS

Data collected between 2011 and 2019 were obtained from the Houston HeartReach Registry. Participants were classified as having or not having each of 4 traditional cardiometabolic risk factors: hypertension, diabetes, body mass index indicating overweight or obesity, and dyslipidemia. Differences in prevalence were compared using the Pearson χ2 test.

RESULTS

Most participants had hypertension, overweight or obesity, and dyslipidemia. Older women (≥65 years) had the highest prevalence of all cardiometabolic risk factors. Black participants had a higher prevalence of hypertension (P = .006) and a lower prevalence of dyslipidemia (P = .009) than non-Black participants. Hispanic participants had a lower prevalence of hypertension (P < .001) and a higher prevalence of overweight or obesity (P = .03) than non-Hispanic participants. Participants in the lowest household income bracket (<$25,000) were more likely to have diabetes (P = .001) and overweight or obesity (P = .004) than participants in the highest income bracket (≥$50,000). Unemployed participants had a higher prevalence of diabetes (P < .001), overweight or obesity (P = .004), and dyslipidemia (P < .001) than employed participants. Comorbidity analysis revealed clustering of multiple cardiometabolic risk factors. Moreover, risk factor hot spots were identified by zip code, which could help select future sites for targeted screening.

CONCLUSION

The analysis found that cardiometabolic risk factor prevalence varies with demographic and socioeconomic status. Geographic areas where cardiometabolic risk factor prevalence was highest were also identified. Further participant recruitment and analysis are required to create predictive models of cardiovascular disease risk in women.

Positive impact of nutrition in the prevention of peripheral vascular disease and severe acute respiratory syndrome coronavirus 2: review

Recent research has shown that there is a link between the trend of cardiovascular disease (CVD), chronic symptoms of SARS-CoV-2 (COVID-19), and medical nutrition therapy. Making positive changes to an individual's lifestyle can help to reduce the symptoms that follow exposure to CVD and COVID-19. Sustainable nutrition and lifestyle changes can positively impact an individual's health. Studies have considered the risk factors associated with the disease, medical history, the link between nutrition and peripheral vascular disease (PVD), symptom management, and the interrelationship between nutrition, COVID-19, and PVD. One study has demonstrated that Western Dietary intake can boost the innate immune system while suppressing humoral response, causing chronic inflammation and poor host defense against viruses. However, further investigation is needed to confirm. Patients with PVD and COVID-19 have experienced a reduction in side effects when prescribed a regimen of medical nutrition therapy, heart-healthy diets, and adequate physical activity before and after symptoms of both diseases appear. This approach has proven to be a protective factor during the combination of both illnesses. Our findings indicate that balanced diet and lifestyle are essential in supporting an optimal immune system that can reduce the risk of virus load in individuals at risk of infection and symptoms from COVID-19 and PVD.

Effect of Comprehensive Educational Program on Preeclamptic Women's Risk Perception of Cardiovascular Disease, Self-Efficacy, and Adherence to Healthy Lifestyle Behaviors

PURPOSE

To evaluate the effect of a comprehensive educational program on preeclamptic women's knowledge, risk perception of cardiovascular disease, self-efficacy, and adherence to healthy lifestyle behaviors.

PATIENTS AND METHODS

This study employed a pretest-posttest design. One hundred and two women who previously had preeclampsia were enrolled from July 2022 to December 2022 from outpatient obstetrics, gynecology, and family planning clinics. The primary and secondary outcomes were measured at baseline, after eight weeks, and after three months of the educational intervention. The data were analyzed using SPSS version 23, descriptive and inferential statistics, specifically the Chi-square test, independent t-tests, and repeated measures ANOVA.

RESULTS

A statistically significant difference was found between the two groups immediately post-intervention and the three-month follow-up, with a significant improvement among the intervention group than control group regarding cardiovascular disease knowledge (p < 0.001), risk perception (p < 0.001), self-efficacy (p < 0.001), and healthy lifestyle behaviors (p < 0.001). There was a statistically significant interaction between group and time regarding total cardiovascular disease risk perception (F = 203.67, p < 0.001, η2 = 0.673), self-efficacy (F = 70.06, p < 0.001, η2 = 0.405), and adherence to healthy lifestyle behaviors (F = 145.08, p < 0.001, η2 = 0.597).

CONCLUSION

This study concluded that the comprehensive educational program had a positive effect on improving preeclamptic women's knowledge and risk perception of CVD, self-efficacy, and adherence to healthy lifestyle behaviors following preeclampsia.

Plasma Levels of Polyols Erythritol, Mannitol, and Sorbitol and Incident Coronary Heart Disease Among Women

BACKGROUND AND AIMS

Erythritol, a sugar alcohol (polyol), has recently been linked to the risks of major adverse cardiovascular events. We investigated whether plasma erythritol and other polyols (mannitol/sorbitol) were associated with the risk of incident coronary heart disease (CHD).

METHODS

This prospective nested case-control study included 762 incident cases of CHD and 762 controls from the Nurses' Health Study. Plasma concentrations of polyols were measured at baseline (1989-90 or 2000-02). Associations of erythritol with cardiometabolic risk factors were also analyzed in the Women's Lifestyle Validation Study (n=728; blood collected in 2010-12).

RESULTS

Higher erythritol levels were related to more adverse cardiometabolic risk factor status. The relative risk (RR) for CHD per 1-SD increment was 1.15 [95% CI: 1.04, 1.28] for erythritol and 1.16 [1.05, 1.28] for mannitol/sorbitol, after adjusting for diet quality, lifestyles, and adiposity. Compared with women in the lowest quartile, those in the highest quartile (Q4) of erythritol had a RR 1.55 [1.13, 2.14] for CHD. The RR in Q4 of erythritol was 1.61 [1.15, 2.24; p=0.006] when hypertension and dyslipidemia were further added to the model; the RR was 1.21 [0.86, 1.70] after adjustment for diabetes. For mannitol/sorbitol, the RR in the Q4 was 1.42 [1.05, 1.91; p=0.022] for CHD in the multivariable-adjusted model including diabetes.

CONCLUSIONS

Higher plasma erythritol and mannitol/sorbitol were related to elevated risks of CHD even after adjustment for diet, lifestyles, adiposity, and other risk factors. The unfavorable association of mannitol/sorbitol, but not erythritol, with CHD risk remained significant independently of diabetes/hyperglycemia.

Sex-Specific Cardiometabolic Determinants of Postoperative Atrial Fibrillation After Cardiac Surgery

BACKGROUND

Cardiometabolic diseases increase the risk of postoperative atrial fibrillation (POAF), a complication leading to higher long-term risk of major cardiovascular events (MACE). It remains unknown whether the effect of these risk factors differs according to sex. We sought to evaluate the sex-specific predictors of POAF after coronary artery bypass grafting (CABG).

METHODS

In a prospective registry of patients undergoing isolated CABG, we compared predictors of POAF between sexes with logistic regression models. Because of high prevalence of abdominal obesity in women, > 80% having a waist circumference (WC) ≥ 88 cm, median WC values were used to define abdominal obesity (men ≥ 102 cm, women ≥ 100 cm).

RESULTS

This analysis included 6177 individuals (17% women). Mean age was 65.6 ± 8.9 years. POAF occurred in 32% of men and 28% of women (P < 0.05). Compared with men, women with POAF had similar WC; higher prevalence of hypertension and diabetes; lower high-density lipoprotein (HDL)-cholesterol; and higher glucose, triglyceride, low- density lipoprotein (LDL)-cholesterol, and C-reactive protein levels (all P < 0.05). After adjustment, age and abdominal obesity were associated with POAF in both sexes (P < 0.05). The interaction of WC with sex suggested a worse impact of WC on POAF risk among women (adjusted odds ratio [OR], 1.97; 95% confidence interval [CI], 1.48-2.62 vs in men 1.33; 95% CI, 1.17-1.50; P for interaction = 0.01).

CONCLUSIONS

Abdominal obesity is a major predictor of POAF in both sexes, with higher risk in women. These results emphasize the need for enhanced strategies to manage abdominal obesity and its cardiometabolic consequences in the general population and the potential to develop sex-specific preventive interventions to reduce risk of POAF.

Association of adverse pregnancy outcomes with cardiovascular risk profiles in later life: Current insights from the Hamburg City Health Study (HCHS)

BACKGROUND AND AIMS

Adverse pregnancy outcomes (APO) have been related to increased cardiovascular (CV) risk and mortality in later life. Underlying pathomechanisms for the development of CV disease in these women are not yet fully understood. In this study, we aimed to investigate the relationship between APO and individual CV risk profiles in later life.

METHODS

We used cross-sectional data from 10,000 participants enrolled in the Hamburg City Health Study (HCHS). We analysed self-reported APO, CV risk factors and health status, including biomarkers, electrocardiogram, echocardiography and vascular ultrasound. To examine associations, Wilcoxon rank sum test and Pearson's χ2-test were performed. Multivariable-adjusted regression models were calculated to determine associations.

RESULTS

N = 1970 women who reported pregnancies were included. Median age was 63 years, 8.7 % reported gestational hypertension (gHTN), 18 % excessive weight gain and 2.4 % gestational diabetes. Ten percent had delivered newborns with birth weight <2.5 kg, 14 % newborns with birth weight >4 kg. In multivariable-adjusted models, significant associations between APO, CV risk profiles and cardiac remodeling were identified. gHTN correlated with higher body mass index (BMI) (Beta 1.68, CI 95 % 0.86-2.50; p < 0.001), hypertension (OR 4.58, CI 95 % 2.79-7.86; p < 0.001), left ventricular remodeling (e.g. left ventricular mass index (Beta 4.46, CI 95 % 1.05-7.87; p = 0.010)) and myocardial infarction (OR 3.27, CI 95 % 0.94-10.07; p = 0.046).

CONCLUSIONS

In this population-based sample, APO were associated with CV risk profiles and cardiac remodeling in later life, suggesting early manifestations of future CV risk during pregnancy. Prospective data is needed for individual risk stratification in women with APO.

Normotensive placental extracellular vesicles provide long-term protection against hypertension and cardiovascular disease

BACKGROUND

Women with normotensive pregnancy are at a reduced risk of developing cardiovascular disease postpartum compared with those who experience hypertensive conditions during pregnancy. However, the underlying mechanisms remain poorly understood. During normotensive pregnancy, vast numbers of placental extracellular vesicles are released into the maternal circulation, which protect endothelial cells from activation and alter maternal vascular tone. We hypothesized that placental extracellular vesicles play a mechanistic role in lowering the risk of cardiovascular disease following normotensive pregnancy.

OBJECTIVE

This study aimed to investigate the long-term effects of placental extracellular vesicles derived from normotensive term placentae on the cardiovascular system and explore the mechanisms underlying their biological effects.

STUDY DESIGN

Spontaneously hypertensive rats were injected with placental extracellular vesicles from normotensive term pregnancies (2 mg/kg each time, n=8) or vehicle control (n=9) at 3 months of age. Blood pressure and cardiac function were regularly monitored from 3 months to 15 months of age. The response of mesenteric resistance arteries to vasoactive substances was investigated to evaluate vascular function. Cardiac remodeling, small artery remodeling, and renal function were investigated to comprehensively assess the impact of placental extracellular vesicles on cardiovascular and renal health.

RESULTS

Compared with vehicle-treated control animals, rats treated with normotensive placental extracellular vesicles exhibited a significantly lower increase in blood pressure and improved cardiac function. Furthermore, the vasodilator response to the endothelium-dependent agonist acetylcholine was significantly enhanced in the normotensive placental extracellular vesicle-treated spontaneously hypertensive rats compared with the control. Moreover, treatment with placental extracellular vesicles reduced wall thickening of small renal vessels and attenuated renal fibrosis.

CONCLUSION

Placental extracellular vesicles from normotensive term pregnancies have long-lasting protective effects reducing hypertension and mitigating cardiovascular damage in vivo.

Nursing intervention with a gender approach in patients with arterial hypertension: a scoping review

This scoping review aims to identify and synthesize the available literature describing the use of the gender approach in research and nursing clinical practice related to hypertension. The review was conducted following the scoping review framework recommended by Arksey and O'Malley. Elements related to content were chosen following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). Data were extracted using a predesigned table and were presented narratively after the content analysis. The PubMed, CINAHL, Web of Science, PsycINFO, Cochrane, Scopus, ScienceDirect and ERIC databases were consulted between March 2022 and June 2024. Reference lists from all sources and gray literature were also reviewed to identify additional publications. A total of 18 studies were finally included in this scoping review. Most of the studies (83 percent) represent gender as a biological variable (sex), and only a few of them (22 percent) analyzed psychological or social differences. In addition, several studies include unequal representations of each sex, most of them use the terms "sex" and "gender" as incorrect or interchangeable, which makes it difficult to evaluate the results from a gender perspective. There is still a substantial gap in the literature related to nurses' intervention with a gender approach in patients with hypertension. Future studies should focus on improving health interventions by considering gender to improve equality and efficiency in health outcomes associated with hypertension and other cardiovascular risk factors.

Exploring Sex Differences in Pain Manifestation of Coronary Artery Disease through Mendelian Randomization

Pain manifestation following coronary artery disease (CAD) disease differs between men and women. Here, we aimed to provide evidence favoring possible differences in pain manifestation between men and women following CAD using Mendelian randomization (MR). We used summary-level data from sex-stratified genome-wide association studies on CAD and self-reported and clinically diagnosed chest, neck and shoulder, back, and facial pain using data from the UK Biobank cohort (N > 450,000) followed by two-sample MR (sensitivity) analyses. We identified 32 and 19 independent genetic variants associated with CAD for men and women, respectively, as instrumental variables. Genetically influenced CAD was associated with a higher risk of self-reported chest pain in both men (OR: 1.27, CI: 1.2-1.33) and women (OR: 1.44, CI: 1.20-1.73), with similar results for clinically diagnosed chest pain (men OR: 1.22, CI: 1.17-1.26; women OR: 1.31, CI: 1.18-1.46). In addition, in women only, genetically influenced CAD was associated with a higher risk of back pain (OR: 1.35, CI: 1.03-1.66) and neck and shoulder pain (OR: 1.22, CI: 0.91-1.63) (p-values for interaction with men: 0.030 and 0.041, respectively). Sensitivity analysis did not indicate the results were biased by directional pleiotropy. We found evidence, based on genetic predisposition for CAD, for different pain manifestations of CAD in men and women. While CAD was associated with chest pain in both sexes, we only found evidence for a higher risk of back pain and neck and shoulder pain in women, supporting common notions that women may present more often with uncharacteristic anginal symptoms.

Sex-specific cardiac remodeling in aged rats after adolescent chronic stress: associations with endocrine and metabolic factors

BACKGROUND

Cardiovascular disease is a leading cause of death worldwide. Rates of cardiovascular disease vary both across the lifespan and between sexes. While multiple factors, including adverse life experiences, impact the development and progression of cardiovascular disease, the potential interactions of biological sex and stress history on the aged heart are unknown. To this end, we examined sex- and stress-specific impacts on left ventricular hypertrophy (VH) after aging. We hypothesized that early-life chronic stress exposure impacts behavioral and physiologic responses that predict cardiac remodeling in a sex-specific manner.

METHODS

Histological analysis was conducted on hearts of male and female rats previously exposed to chronic variable stress during the late adolescent period (postnatal days 43-62). These animals were challenged with a forced swim test and a glucose tolerance test before aging to 15 months and again being challenged. Predictive analyses were then used to isolate factors that relate to cardiac remodeling among these groups.

RESULTS

Early-life chronic stress impacted cardiac remodeling in a sex-specific manner. Among rats with a history of chronic stress, females had increased concentric VH. However, there were few associations within the female groups among individual behavioral and physiologic parameters and cardiac remodeling. While males as a group did not have VH after chronic stress, they exhibited multiple individual associations with cardiac susceptibility. Passive coping in young males and active coping in aged males related to VH in a stress history-dependent manner. Moreover, baseline corticosterone positively correlated with VH in unstressed males, while chronically-stressed males had positive correlations between VH and visceral adiposity.

CONCLUSIONS

These results indicate that females as a group are uniquely susceptible to the effects of early-life stress on cardiac remodeling later in life. Conversely, males have more individual differences in vulnerability, where susceptibility to cardiac remodeling relates to endocrine, metabolic, and behavioral measures depending on stress history. These results ultimately support a framework for assessing cardiovascular risk based on biological sex and prior adverse experiences.

2023 International Evidence-Based Polycystic Ovary Syndrome Guideline Update: Insights From a Systematic Review and Meta-Analysis on Elevated Clinical Cardiovascular Disease in Polycystic Ovary Syndrome

BACKGROUND

Polycystic ovary syndrome (PCOS) is the most prevalent female endocrinopathy. Although increased cardiovascular risk factors are well established for the syndrome, PCOS remains overlooked within the realm of cardiology. We conducted a systematic review and meta-analysis on the risk of clinical cardiovascular disease (CVD) events in women with PCOS to inform the 2023 International Evidence-Based PCOS Guideline.

METHODS AND RESULTS

A systematic review and meta-analysis was conducted comparing the risk of clinical CVD events in women with and without PCOS. Medline (Ovid), PsycInfo (Ovid), EMBASE, All EBM (Ovid), and CINAHL were searched from January 1, 2017, until March 1, 2023, to update the 2018 PCOS Guideline. Pooled odds ratios (ORs), incidence rate ratios (IRRs), and hazard ratios (HRs) were calculated. Twenty studies involving 1.06 million women (369 317 with PCOS and 692 963 without PCOS) were included. PCOS was associated with higher risk of composite CVD (OR, 1.68 [95% CI, 1.26-2.23]; I2 = 71.0%), composite ischemic heart disease (OR, 1.48 [95% CI, 1.07-2.05]; I2 = 81.0%), myocardial infarction (OR, 2.50 [95% CI, 1.43-4.38]; I2 = 83.3%), and stroke (OR, 1.71 [95% CI, 1.20-2.44]; I2 = 81.4%). The relationship with cardiovascular mortality was less clear (OR, 1.19 [95% CI, 0.53-2.69]; I2 = 0%). Meta-analyses of IRRs support these findings. Results from pooled HRs were limited by the small number of studies and significant heterogeneity.

CONCLUSIONS

This review provides evidence and highlights the importance of recognizing PCOS as a significant risk factor for CVD morbidity. The 2023 International Evidence-Based PCOS Guideline now recommends awareness of increased CVD risk and comprehensive risk assessment in PCOS to help mitigate the burden of CVD in this common and high-risk condition.

Inequalities for women diagnosed with distal arch and descending thoracic aortic aneurysms: results from the Effective Treatments for Thoracic Aortic Aneurysms (ETTAA) cohort study

BACKGROUND

Women with thoracic aortic aneurysms within the arch or descending thoracic aorta have poorer survival than men. Sex differences in relative thoracic aortic aneurysm size may account for some of the discrepancy. The aim of this study was to explore whether basing clinical management on aneurysm size index (maximum aneurysm diameter/body surface area) rather than aneurysm size can restore equality of survival by sex.

METHODS

The Effective Treatments for Thoracic Aortic Aneurysms (ETTAA; ISRCTN04044627) study was a prospective, observational cohort study. Adults referred to National Health Service hospitals in England with new/existing arch or descending thoracic aorta aneurysms greater than or equal to 4 cm in diameter were followed from March 2014 to March 2022. Baseline characteristics and survival to intervention and overall were compared for men and women. Survival models were used to assess the association between all-cause survival and sex, with and without adjustment for aneurysm diameter or aneurysm size index.

RESULTS

A total of 886 thoracic aortic aneurysm patients were recruited: 321 (36.2%) women and 565 (63.8%) men. The mean(s.d.) aneurysm diameter was the same for women and men (5.7(1.1) versus 5.7(1.2) cm respectively; P = 0.751), but the mean(s.d.) aneurysm size index was greater for women than for men (3.32(0.80) versus 2.83(0.63) respectively; P < 0.001). Women had significantly worse survival without intervention: 110 (34.3%) women and 135 (23.9%) men (log rank test, P < 0.001). All-cause mortality remained greater for women after adjustment for diameter (HR 1.65 (95% c.i. 1.35 to 2.02); P < 0.001), but was attenuated after adjustment for aneurysm size index (HR 1.11 (95% c.i. 0.89 to 1.38); P = 0.359). Similar results were found for all follow-up, with or without intervention, and findings were consistent for descending thoracic aorta aneurysms alone.

CONCLUSION

Guidelines for referral to specialist services should consider including aneurysm size index rather than diameter to reduce inequity due to patient sex.

Ten-Year Review of the Postpartum Maternal Health Clinic at the Kingston Health Sciences Centre

OBJECTIVES

The postpartum Maternal Health Clinic (MHC) sees patients who have experienced pregnancy complications identified as pregnancy-related cardiovascular disease (CVD) risk indicators (hypertensive disorders of pregnancy, gestational diabetes, placental abruption, idiopathic preterm delivery, and intrauterine growth restriction) at 6 months postpartum for CVD risk screening. This project aimed to summarise the past 10 years of the MHC and identify trends in patient characteristics, patient CVD risk assessments, and clinic attendance over time.

METHODS

Patients included in this study have experienced 1 or more pregnancy-related CVD risk indicator(s) and have delivered between April 2011 and April 2021. MHC patient data and the Better Outcomes Registry Network database were utilised to compare eligible and participating patient data during clinically significant time periods.

RESULTS

The clinic has seen 1030 patients in the last 10 years and their characteristics have remained largely consistent. However, there has been an increase in the proportion of patients seen because of a hypertensive disorder and an increase in the proportion of patients with obesity, abnormal total cholesterol, and elevated fasting glucose. Additionally, CVD risk scores and the prevalence of metabolic syndrome have remained consistent over the years. Regarding the clinic's outreach, patient eligibility for the MHC has been increasing while attendance has been decreasing over time.

CONCLUSIONS

Overall, there remains a need to screen these patients for CVD risk and counsel them on risk reduction. There is also an opportunity to increase patient recruitment to improve attendance and to address the increased need for CVD risk screening and counselling in the community.

Contraceptive counselling and uptake of contraception among women with cardiovascular diseases: a systematic review and meta-analysis

To address the lack of clarity regarding contraceptive counselling and uptake of contraception among women with cardiovascular disease (CVD), this study aimed to conduct a systematic review and meta-analysis on contraceptive counselling and the subsequent uptake of contraception among women with CVD. A search across six databases identified 1228 articles, with 11 studies (2580 participants) included. The pooled prevalence of contraceptive counselling was 63%, varying from 36 to 94% in individual studies. Inconsistent delivery and documentation of counselling were noted, along with a lack of knowledge about pregnancy complications and misconceptions regarding CVD severity. For contraceptive uptake (n = 5), the pooled prevalence was 64% (95% confidence interval, 45 to 82%). Women with CVD were also found to use less effective methods as well as methods not recommended for their condition (e.g., combined hormonal methods among participants with absolute or relative contraindications). Improving contraceptive counselling and choices for women with CVD can not only enhance knowledge and decision-making for women with CVD in line with their reproductive goals and preferences but reduce high-risk unintended pregnancies and adverse pregnancy outcomes.

Sex Differences in Characteristics, Resource Utilization, and Outcomes of Cardiogenic Shock: Data From the Critical Care Cardiology Trials Network (CCCTN) Registry

BACKGROUND

Sex disparities exist in the management and outcomes of various cardiovascular diseases. However, little is known about sex differences in cardiogenic shock (CS). We sought to assess sex-related differences in the characteristics, resource utilization, and outcomes of patients with CS.

METHODS

The Critical Care Cardiology Trials Network is a multicenter registry of advanced cardiac intensive care units (CICUs) in North America. Between 2018 and 2022, each center (N=35) contributed annual 2-month snapshots of consecutive CICU admissions. Patients with CS were stratified as either CS after acute myocardial infarction or heart failure-related CS (HF-CS). Multivariable logistic regression was used for analyses.

RESULTS

Of the 22 869 admissions in the overall population, 4505 (20%) had CS. Among 3923 patients with CS due to ventricular failure (32% female), 1235 (31%) had CS after acute myocardial infarction and 2688 (69%) had HF-CS. Median sequential organ failure assessment scores did not differ by sex. Women with HF-CS had shorter CICU lengths of stay (4.5 versus 5.4 days; P<0.0001) and shorter overall lengths of hospital stay (10.9 versus 12.8 days; P<0.0001) than men. Women with HF-CS were less likely to receive pulmonary artery catheters (50% versus 55%; P<0.01) and mechanical circulatory support (26% versus 34%; P<0.0001) compared with men. Women with HF-CS had higher in-hospital mortality than men, even after adjusting for age, illness severity, and comorbidities (34% versus 23%; odds ratio, 1.76 [95% CI, 1.42-2.17]). In contrast, there were no significant sex differences in utilization of advanced CICU monitoring and interventions, or mortality, among patients with CS after acute myocardial infarction.

CONCLUSIONS

Women with HF-CS had lower use of pulmonary artery catheters and mechanical circulatory support, shorter CICU lengths of stay, and higher in-hospital mortality than men, even after accounting for age, illness severity, and comorbidities. These data highlight the need to identify underlying reasons driving the differences in treatment decisions, so outcomes gaps in HF-CS can be understood and eliminated.

Sex Differences in the Relationship Between Self-Reporting of Snoring and Cardiovascular Risk:An Analysis of NHANES

Background

Identifying risk factors for cardiovascular disease (CVD) is critical for effective prevention and management. While classic CVD risk factors have been extensively studied, there is a scarcity of research on the association between snoring and CVD risk, particularly in the context of sex differences.

Methods

This study utilized data from the National Health and Nutrition Examination Survey (NHANES) conducted between 2015 and 2020. Participants were initially categorized based on the severity of snoring or the presence of snoring.Within the snoring group, they were further classified by sex. Analysis was carried out using multivariate logistic regression.

Results

Our study included 12,681 participants aged 18 years or older. When compared to the non-snoring group, individuals in the moderate snoring group had a higher odds ratio (OR) of 1.418 (95% CI 1.083 to 1.857, p = 0.011), while those in the severe snoring group had a higher OR of 1.882 (95% CI 1.468 to 2.409, p < 0.001). In the snoring group, individuals were further categorized by gender: 4527 males and 4131 females. Importantly, male patients showed a higher OR for atrial fibrillation (4.945, 95% CI 1.187 to 20.598, p = 0.028) compared to females. Additionally, male patients had a higher OR for coronary heart disease (2.002, 95% CI 1.152 to 3.479, p = 0.014) compared to females.

Conclusion

Sex plays a significant role in the relationship between snoring and CVD risk. Males with snoring have a higher risk of developing CVD compared to females. In particular, male snorers are nearly five times more likely to develop atrial fibrillation and about twice as likely to experience coronary artery disease in comparison to female snorers. It is recommended that healthcare providers and public health officials prioritize cardiovascular risk assessments for male individuals who exhibit symptoms of snoring.

Atherosclerotic Cardiovascular Disease Novel and Traditional Risk Factors in Middle Eastern Young Women. The ANCORS-YW Study

Background

There is paucity of data on the prevalence of novel and traditional cardiovascular risk factors in young women with atherosclerotic cardiovascular disease (ASCVD) in the Middle East. We sought to evaluate clinical profiles and prevalence of novel and traditional risk factors in Middle Eastern young women with ASCVD compared with age-matched controls.

Methods

Women 18-50 years of age who have ASCVD were enrolled and each was aged-matched with two women with no ASCVD. Prevalence of novel and traditional risk factors was compared in the two groups. Multivariable analyzes examined the independent association of 16 factors with ASCVD.

Results

Of 627 young women enrolled mean age 44.1 ± 5.2 years; 209 had ASCVD and 418 served as controls. Women with ASCVD had significantly higher prevalence of five of the studied traditional risk factors (hypertension, type 2 diabetes [T2D], smoking, low-density lipoprotein cholesterol serum levels, and family history of premature ASCVD [FHx]) than women with no ASCVD. Additionally, of the 11 novel and psychosocial risk factors studied, four showed significantly higher prevalence in young women with ASCVD (preterm delivery, hypertensive disease of pregnancy gestational diabetes, and low level of education). Multivariable analyzes showed hypertension, T2D, smoking, FHx, persistent weight gain after pregnancy and low level of education were independently associated with ASCVD.

Conclusions

In this study of young Middle Eastern women; traditional risk factors as well as persistent weight gain after pregnancy were more prevalent in women with ASCVD compared with controls.The study is registered with ClinicalTrials.gov, unique identifier number NCT04975503.

Combination of large-volume sample stacking with polarity switching and micelle electrokinetic chromatography for the analysis of anion compounds in Yangxinshi tablets

INTRODUCTION

Yangxinshi tablet (YXST) is a traditional Chinese medicine preparation characterized by its high efficacy and safety for the treatment of cardiovascular diseases. Anionic compounds have been revealed as potential active components. However, there is currently limited research regarding its quality control.

OBJECTIVE

We aimed to establish a strategy for the simultaneous separation and determination of five key anionic compounds in YXST.

METHOD

A sensitive and efficient analytical method was developed and applied for the simultaneous separation and determination of five key compounds in YXST using large-volume sample stacking with polarity switching and micelle electrokinetic chromatography (LVSS-PS-MEKC) coupled with diode array detection. Crucial parameters, including sample volume, applied voltage, composition and pH of the running buffer, concentration of organic modifier, and switching time of the polarity, were systematically evaluated and optimized using a single variable method to enhance separation performance. Furthermore, the impact of cyclodextrin and sodium dodecyl sulfate as electrolyte modifiers was also investigated.

RESULTS

Under the optimal conditions, baseline separation of the five compounds (daidzein, puerarin, glycyrrhiztinic acid, chlorogenic acid, and salvianolic acid B) was achieved within 20 min. In comparison to the conventional MEKC mode, the constructed LVSS-PS-MEKC method exhibited a more than sixfold increase in the enrichment factor. The method was validated in terms of linearity, precision, accuracy, 24 h stability, and recovery and successfully applied to analyze YXST samples.

CONCLUSION

A sensitive strategy was developed for the simultaneous separation and determination of five key anionic components in YXST, offering a robust and efficient strategy for pharmaceutical analysis.

Long-term continuous exercise training counteracts the negative impact of the menopause transition on cardiometabolic health in hypertensive women - a 9-year RCT follow-up

PURPOSE

The study examined effects of 9-yrs of multicomponent exercise training during the menopause interval on cardiometabolic health in hypertensive women.

METHODS

Sedentary, middle-aged women (n = 25) with mild-to-moderate arterial hypertension were randomized into a soccer training (multicomponent exercise; EX; n = 12) or control group (CON; n = 13). EX took part in 1-h football training sessions, 1-3 times weekly, for a consecutive 9-years, totaling ∼800 training sessions, while CON did not take part in regular exercise training. 22 participants entered menopause during the intervention.

RESULTS

A time×group interaction effect (P = 0.04) of 8.5 mmHg in favour of EX was observed for changes in mean arterial pressure (MAP) (EX: -4.8 [-10.7;1.1] mmHg, CON +3.7 [-2.0;9.3] mmHg). Time×group interaction effects in favour of EX were also observed for total body weight (4.6 kg, P = 0.008, EX: +0.7 [-1.7;3.0] kg, CON: +5.3 [3.0;7.6] kg, total fat percentage (5.7%-points, P = 0.02; EX (-1.9 [-4.4;0.6] %-points; P = 0.13), CON +3.8 [1.4;6.2] %-points and for total cholesterol (1.2 mmol/l, P = 0.03, EX: -0.5 [-1.0;-0.1] mmol/l, CON: +0.7 [0.2;1.1] mmol/l. EX reduced (P = 0.02) plasma low-density lipoprotein cholesterol by -0.4 [-0.8;-0.1] mmol/l, whereas an increase (P = 0.01) of 0.4 [0.1;0.8] mmol/l occurred in CON (interaction. P < 0.001). A time×group interaction (P = 0.004) existed for changes in exercise capacity in favour of EX. Fasting glucose remained unchanged in EX and increased (P < 0.001) by 0.7 [0.4;1.0] mmol/l in CON (time×group interaction P = 0.02).

CONCLUSION

In conclusion, long-term multicomponent exercise training fully counteracts the detrimental effects of the menopause transition on cardiometabolic health in hypertensive women.

Factors influencing the association between depressive symptoms and cardiovascular disease in US population

Cardiovascular disease (CVD) and depression are common diseases that lead to adverse health outcomes. Depressive Symptoms may be a risk factor for CVD. But few studies focused on the impact of socioeconomic factors, common medical history and dietary intake about this association. This study analyzed National Health and Nutrition Examination Survey (NHANES) 2007-2016. Complex sampling-weighted logistic regression models were used to compare the odds ratios (ORs) of CVD in participants with different depressive symptoms. 11,516 NHANES participants aged ≥ 40 years were included in the final analysis, of whom 1842 had CVD. Compared with participants with no/minimal depression, participants with mild, moderate, and moderately severe/severe depression had OR values of 1.25 (95%  CI 1.01-1.54), 1.98 (95% CI 1.32-2.96), and 2.41 (95% CI 1.63-3.57). The association of depressive symptoms with CVD follow a dose-dependent pattern. The interactions of depressive symptoms with gender (Interaction P = 0.009), diabetes (Interaction P = 0.010), household income level (Interaction P = 0.002), dietary cholesterol intake (Interaction P = 0.017) on CVD were observed. More severe depressive symptoms are associated with increased risk of CVD in US population. The association may be more pronounced in the female population, population with diabetes, low family income level, or high dietary cholesterol intake.

Linking Myocardial Infarction and Frailty Status at Old Age in Europe: Moderation Effects of Country and Gender

BACKGROUND

Myocardial infarction (MI) is a serious condition affecting a considerable number of individuals, with important clinical consequences. Understanding the associated factors is crucial for effective management and prevention. This study aimed to (1) examine the association between MI and frailty in a sample of older European adults and (2) investigate the moderating effects of country and gender on this association.

METHODS

A cross-sectional survey of 22,356 Europeans aged 60 years and older was conducted. The data come from the sixth wave of the Survey of Health, Ageing and Retirement in Europe. Frailty, MI, gender, and country were studied.

RESULTS

Frailty is strongly associated with MI. Robust older adults are 13.31 times more likely not to have an MI. However, these odds drop to 5.09 if pre-frail and to 2.73 if frail. Gender, but not country, moderates this relationship. There is a strong association between MI and frailty in men, whereas for women, the association is not as strong.

CONCLUSIONS

Frailty is highly associated with MI in European older adults. Country did not moderate the link between frailty and MI but gender does, with the relationship being notably stronger in men. The frailty-MI association remained significant even when controlling for a number of personal conditions and comorbidities.

Associations of life's essential 8 with extent of multi-territorial atherosclerotic plaques and stenosis: a cross-sectional study

BACKGROUND

Life's Essential 8 (LE8), the recently updated construct for quantifying cardiovascular health, is related to the risks of cardiovascular events. The present study aimed to evaluate associations of LE8 score with the multi-territorial extent of atherosclerosis in a community-dwelling population.

METHODS

Data were derived from the baseline cross-sectional survey of the PolyvasculaR Evaluation for Cognitive Impairment and vaScular Events (PRECISE) study in Lishui City. The LE8 included overall, medical and behavior LE8 scores, and were categorized as low (< 60), moderate (60-<80), and high (≥ 80) groups. Vascular magnetic resonance imaging was used to evaluate intracranial and extracranial arteries; thoracoabdominal computed tomography angiography to evaluate coronary, subclavian, aorta, renal, ilio-femoral arteries; and ankle-brachial index to evaluate peripheral arteries. The presence of atherosclerotic plaque or stenosis in any territory was defined as plaque or vascular stenosis with 1 territory affected or more in these arteries. The extent of atherosclerotic plaques or stenosis was assessed according to the number of these 8 vascular sites affected, and graded as four grades (none, single territory, 2-3 territories, 4-8 territories).

RESULTS

Of 3065 included participants, the average age was 61.2 ± 6.7 years, and 53.5% were women (n = 1639). The moderate and high overall LE8 groups were associated with lower extent of multi-territorial plaques [common odds ratio (cOR) 0.44, 95% confidence interval (CI), 0.35-0.55; cOR 0.16, 95%CI, 0.12-0.21; respectively] and stenosis (cOR 0.51, 95%CI, 0.42-0.62; cOR 0.16, 95%CI, 0.12-0.21; respectively) after adjustment for potential covariates. Similar results were observed for medical LE8 score with the extent of multi-territorial plaques and stenosis (P < 0.05). We also found the association between behavior LE8 score and the extent of multi-territorial stenosis (P < 0.05).

CONCLUSIONS

The higher LE8 scores, indicating healthier lifestyle, were associated with lower presence and extent of atherosclerotic plaque and stenosis in southern Chinese adults. Prospective studies are needed to further validate these findings.

Hypertensive disorders of pregnancy and long-term maternal cardiovascular risk: Bridging epidemiological knowledge into personalized postpartum care and follow-up

Cardiovascular disease (CVD) is globally the leading cause of death and disability. Sex-specific causes of female CVD are under-investigated. Pregnancy remains an underinvestigated sex-specific stress test for future CVD and a hitherto missed opportunity to initiate prevention of CVD at a young age. Population-based studies show a strong association between female CVD and hypertensive disorders of pregnancy. This association is also present after other pregnancy complications that are associated with placental dysfunction, including fetal growth restriction, preterm delivery and gestational diabetes mellitus. Few women are, however, offered systematic cardio-preventive follow-up after such pregnancy complications. These women typically seek help from the health system at first clinical symptom of CVD, which may be decades later. By this time, morbidity is established and years of preventive opportunities have been missed out. Early identification of modifiable risk factors starting postpartum followed by systematic preventive measures could improve maternal cardiovascular health trajectories, promoting healthier societies. In this non-systematic review we briefly summarize the epidemiological associations and pathophysiological hypotheses for the associations. We summarize current clinical follow-up strategies, including some proposed by international and national guidelines as well as user support groups. We address modifiable factors that may be underexploited in the postpartum period, including breastfeeding and blood pressure management. We suggest a way forward and discuss the remaining knowledge gaps and barriers for securing the best evidence-based follow-up, relative to available resources after a hypertensive pregnancy complication in order to prevent or delay onset of premature CVD.

Proteomic Analysis and Sex-Specific Changes in Chronically Ischemic Swine Myocardium Treated with Sodium-Glucose Cotransporter-2 Inhibitor Canagliflozin

BACKGROUND

Although sodium-glucose cotransporter-2 inhibitors have been shown to improve cardiovascular outcomes in general, little is presently known about any sex-specific changes that may result from this therapy. We sought to investigate and quantify potential sex-specific changes seen with the sodium-glucose cotransporter-2 inhibitor canagliflozin (CAN) in a swine model of chronic myocardial ischemia.

STUDY DESIGN

Eighteen Yorkshire swine underwent left thoracotomy with placement of an ameroid constrictor. Two weeks postop, swine were assigned to receive either control (F = 5 and M = 5) or CAN 300 mg daily (F = 4 and M = 4). After 5 weeks of therapy, swine underwent myocardial functional measurements, and myocardial tissue was sent for proteomic analysis.

RESULTS

Functional measurements showed increased cardiac output, stroke volume, ejection fraction, and ischemic myocardial flow at rest in male swine treated with CAN compared with control male swine (all p < 0.05). The female swine treated with CAN had no change in cardiac function as compared with control female swine. Proteomic analysis demonstrated 6 upregulated and 97 downregulated proteins in the CAN female group compared with the control female group. Pathway analysis showed decreases in proteins in the tricarboxylic acidic cycle. The CAN male group had 639 upregulated and 172 downregulated proteins compared with control male group. Pathway analysis showed increases in pathways related to cellular metabolism and decreases in pathways relevant to the development of cardiomyopathy and to oxidative phosphorylation.

CONCLUSIONS

Male swine treated with CAN had significant improvements in cardiac function that were not observed in female swine treated with CAN. Moreover, CAN treatment in male swine was associated with significantly more changes in protein expression than in female swine treated with CAN. The increased proteomic changes seen in the CAN male group likely contributed to the more robust changes in cardiac function seen in male swine treated with CAN.

Association of cardiovascular risk factors and myocardial hypertrophy in women with preeclampsia history

AIMS

A historic of preeclampsia (PE) has been associated with cardiovascular disease (CVD) in women. There are substantial evidences that cardiovascular changes resulting from PE can persist even after pregnancy end. Therefore, the aims was to evaluate the prevalence of myocardial hypertrophy in young women 12 months after PE event as well as try to identify risk factors for these changes.

MATERIALS AND METHODS

Single-center observational prospective cross-sectional study that included 118 consecutive patients after 12 months of PE. Clinical and laboratory evaluations, echocardiogram were performed. Myocardial hypertrophy (LVH) was defined as an index myocardial mass ≥ 45 g/m2.7, for women. Classical risk factors for CVD were considered. Analysis included linear or logistic regression and Spearman's correlation coefficient. Significance level of 5 %.

KEY FINDINGS

Systemic arterial hypertension (SAH) was identified in 52 patients (44 %), overweight/obesity (OOB) in 82 (69 %), dyslipidemia in 68 (57 %) and metabolic syndrome in 47 patients (40 %). LVH was present in 35 cases (29 %) and associated with OOB (OR = 4.51; CI95%:1.18-17.17, p < 0.001), in a model corrected for age and SAH diagnosis. When only the metabolic syndrome components were analyzed, in the multiple logistic regression model, the abdominal circumference was the only clinical variable associated with LVH (OR = 17.65; CI95%:3.70-84.17; p < 0.001).

SIGNIFICANCE

It was observed a high prevalence of ventricular hypertrophy in young women with a history of pre-eclampsia. This condition was associated with the presence of obesity.

Unique features of dyslipidemia in women across a lifetime and a tailored approach to management

Purpose of Review

Cardiovascular disease is a leading cause of death worldwide. Dyslipidemia is a critical modifiable risk factor for the prevention of cardiovascular disease. Dyslipidemia affects a large population of women and is especially pervasive within racial/ethnic minorities.

Recent Findings

Dyslipidemia in pregnancy leads to worse outcomes for patients and creates increased cardiovascular risk for women at an older age. However, women remain underscreened and undertreated compared to men. Females also comprise a small portion of clinical trial participants for lipid lowering agents with increased disease prevalence compared to trial representation. However, recent lipid trials have shown different efficacies of therapies such as ezetimibe, inclisiran, and bempedoic acid with a greater relative benefit for women.

Summary

Pathophysiology of dyslipidemia varies between men and women and across a woman's lifetime. While increased lipid levels or lipid imbalances are more common in postmenopausal women over age 50, conditions such as PCOS and FH produce higher cardiovascular risk for young women.Best practices for management of women with dyslipidemia include early screening with lifestyle intervention and pharmacotherapy with statin and non-statin agents to achieve guideline directed LDL-C thresholds.

Gender Matters: A Multidimensional Approach to Optimizing Cardiovascular Health in Women

Cardiovascular diseases remain a leading cause of mortality among women, yet they are often underestimated and insufficiently addressed. This narrative review delves into the gender disparities in cardiovascular health, underscoring the critical importance of recognizing and addressing the unique challenges women face. The article explores the pathophysiological differences between men and women, highlighting the role of hormonal factors, such as estrogen and menopause, in conferring cardioprotection or increasing risk. It examines the complexities of diagnosis and assessment, including differences in symptom presentation, diagnostic accuracy, and the challenges of interpreting non-invasive testing in women. The review also highlights the need for tailored risk assessment and prevention strategies, incorporating sex-specific conditions and pregnancy-related factors. It emphasizes the importance of lifestyle modifications and interventions, as well as the potential benefits of personalized treatment approaches, considering gender-specific variations in medication responses and cardiac interventions. Furthermore, the article sheds light on the impact of psychosocial and sociocultural factors, such as gender norms, mental health considerations, and access to healthcare, on women's cardiovascular health. It also addresses the significant gaps and challenges in research, including the historical underrepresentation of women in clinical trials and the lack of sex- and gender-sensitive studies. Finally, the review advocates for a multidisciplinary approach, involving patient-centered care, shared decision-making, and collaboration among policymakers, stakeholders, and healthcare systems. This comprehensive strategy aims to enhance awareness, prevention, diagnosis, and treatment of cardiovascular disease in women, ultimately improving health outcomes and reducing the burden of this often overlooked epidemic.

Achieving Equity in EMS Care and Patient Outcomes Through Quality Management Systems: A Position Statement

Improving health and safety in our communities requires deliberate focus and commitment to equity. Inequities are differences in access, treatment, and outcomes between individuals and across populations that are systemic, avoidable, and unjust. Within health care in general, and Emergency Medical Services (EMS) in particular, there are demonstrated inequities in the quality of care provided to patients based on a number of characteristics linked to discrimination, exclusion, or bias. Given the critical role that EMS plays within the health care system, it is imperative that EMS systems reduce inequities by delivering evidence-based, high-quality care for the communities and patients we serve. To achieve equity in EMS care delivery and patient outcomes, the National Association of EMS Physicians recommends that EMS systems and agencies:make health equity a strategic priority and commit to improving equity at all levels.assess and monitor clinical and safety quality measures through the lens of inequities as an integrated part of the quality management process.ensure that data elements are structured to enable equity analysis at every level and routinely evaluate data for limitations hindering equity analysis and improvement.involve patients and community stakeholders in determining data ownership and stewardship to ensure its ongoing evolution and fitness for use for measuring care inequities.address biases as they translate into the quality of care and standards of respect for patients.pursue equity through a framework rooted in the principles of improvement science.

Assessment of knowledge, attitudes, and practices regarding cardiovascular diseases (CVDs) among older individuals of rural Bangladesh: findings from a face-to-face interview

Introduction

Cardiovascular diseases (CVDs) stand as the foremost contributor to global mortality, claiming roughly 17.9 million lives each year, constituting 32.1% of total fatalities. Their impact is notably profound in economies such as Bangladesh, exacting a substantial economic burden. Consequently, grasping the landscape of knowledge, attitudes, and practices is essential for timely identification and prevention strategies.

Methods

This cross-sectional study, carried out between January and May 2023 in the rural regions of Zirani, Savar Upazila, Dhaka, Bangladesh, utilized convenient sampling and conducted face-to-face interviews using a semi-structured questionnaire. It encompassed socio-demographic factors, as well as knowledge, attitudes, and practices concerning CVDs. Data analysis employed descriptive statistics, chi-square tests, and regression analyses, utilizing both the R programming language and SPSS (Version 26).

Result

A total of 424 participants aged 60 years and above were included. The majority were male (60.8%), and the mean age was 71.21 ± 9.21 years, 57.3% were between 60 and 70 years old. Factors such as education, monthly family income, high blood pressure, diabetes, and non-smoking. Were significantly associated with higher knowledge, attitudes and practices scores.

Conclusion

This study illuminates CVD-related KAP among rural Older Individuals in Bangladesh, revealing significant associations between factors such as education, monthly family income, high blood pressure, and non-smoking, with higher scores in knowledge, attitudes, and practices regarding cardiovascular health. These insights underscore the importance of addressing socio-economic factors and health behaviors in developing targeted interventions for the prevention and management of cardiovascular diseases in this demographic.

Sex-Associated Metabolites and Incident Stroke, Incident Coronary Heart Disease, Hypertension, and Chronic Kidney Disease in the REGARDS Cohort

BACKGROUND

Sex disparities exist in cardiometabolic diseases. Metabolomic profiling offers insight into disease mechanisms, as the metabolome is influenced by environmental and genetic factors. We identified metabolites associated with sex and determined if sex-associated metabolites are associated with incident stoke, incident coronary heart disease, prevalent hypertension, and prevalent chronic kidney disease.

METHODS AND RESULTS

Targeted metabolomics was conducted for 357 metabolites in the REGARDS (Reasons for Geographic and Racial Differences in Stroke) case-cohort substudy for incident stroke. Weighted logistic regression models were used to identify metabolites associated with sex in REGARDS. Sex-associated metabolites were replicated in the HyperGEN (Hypertension Genetic Epidemiology Network) and using the literature. Weighted Cox proportional hazard models were used to evaluate associations between metabolites and incident stroke. Cox proportional hazard models were used to evaluate associations between metabolites and incident coronary heart disease. Weighted logistic regression models were used to evaluate associations between metabolites and hypertension and chronic kidney disease. Fifty-one replicated metabolites were associated with sex. Higher levels of 6 phosphatidylethanolamines were associated with incident stroke. No metabolites were associated with incident coronary heart disease. Higher levels of uric acid and leucine and lower levels of a lysophosphatidylcholine were associated with hypertension. Higher levels of indole-3-lactic acid, 7 phosphatidylethanolamines, and uric acid, and lower levels of betaine and bilirubin were associated with chronic kidney disease.

CONCLUSIONS

These findings suggest that the sexual dimorphism of the metabolome may contribute to sex differences in stroke, hypertension, and chronic kidney disease.

Use of Machine Learning for Early Detection of Maternal Cardiovascular Conditions: Retrospective Study Using Electronic Health Record Data

BACKGROUND

Cardiovascular conditions (eg, cardiac and coronary conditions, hypertensive disorders of pregnancy, and cardiomyopathies) were the leading cause of maternal mortality between 2017 and 2019. The United States has the highest maternal mortality rate of any high-income nation, disproportionately impacting those who identify as non-Hispanic Black or Hispanic. Novel clinical approaches to the detection and diagnosis of cardiovascular conditions are therefore imperative. Emerging research is demonstrating that machine learning (ML) is a promising tool for detecting patients at increased risk for hypertensive disorders during pregnancy. However, additional studies are required to determine how integrating ML and big data, such as electronic health records (EHRs), can improve the identification of obstetric patients at higher risk of cardiovascular conditions.

OBJECTIVE

This study aimed to evaluate the capability and timing of a proprietary ML algorithm, Healthy Outcomes for all Pregnancy Experiences-Cardiovascular-Risk Assessment Technology (HOPE-CAT), to detect maternal-related cardiovascular conditions and outcomes.

METHODS

Retrospective data from the EHRs of a large health care system were investigated by HOPE-CAT in a virtual server environment. Deidentification of EHR data and standardization enabled HOPE-CAT to analyze data without pre-existing biases. The ML algorithm assessed risk factors selected by clinical experts in cardio-obstetrics, and the algorithm was iteratively trained using relevant literature and current standards of risk identification. After refinement of the algorithm's learned risk factors, risk profiles were generated for every patient including a designation of standard versus high risk. The profiles were individually paired with clinical outcomes pertaining to cardiovascular pregnancy conditions and complications, wherein a delta was calculated between the date of the risk profile and the actual diagnosis or intervention in the EHR.

RESULTS

In total, 604 pregnancies resulting in birth had records or diagnoses that could be compared against the risk profile; the majority of patients identified as Black (n=482, 79.8%) and aged between 21 and 34 years (n=509, 84.4%). Preeclampsia (n=547, 90.6%) was the most common condition, followed by thromboembolism (n=16, 2.7%) and acute kidney disease or failure (n=13, 2.2%). The average delta was 56.8 (SD 69.7) days between the identification of risk factors by HOPE-CAT and the first date of diagnosis or intervention of a related condition reported in the EHR. HOPE-CAT showed the strongest performance in early risk detection of myocardial infarction at a delta of 65.7 (SD 81.4) days.

CONCLUSIONS

This study provides additional evidence to support ML in obstetrical patients to enhance the early detection of cardiovascular conditions during pregnancy. ML can synthesize multiday patient presentations to enhance provider decision-making and potentially reduce maternal health disparities.

Serum SERCA2a levels in heart failure patients are associated with adverse events after discharge

Calcium homeostasis imbalance is one of the important pathological mechanisms in heart failure. Sarco/endoplasmic reticulum Ca2+-ATPase (SERCA2a), a calcium ATPase on the sarcoplasmic reticulum in cardiac myocytes, is a myocardial systolic-diastolic Ca2 + homeostasis regulating enzyme that is not only involved in cardiac diastole but also indirectly affects cardiac myocyte contraction. SERCA2a expression was found to be decreased in myocardial tissue in heart failure, however, there are few reports on serum SERCA2a expression in patients with heart failure, and this study was designed to investigate whether serum SERCA2a levels are associated with the occurrence of adverse events after discharge in patients hospitalized with heart failure. Patients with heart failure hospitalized in the cardiovascular department of the Second Affiliated Hospital of Guangdong Medical University, China, from July 2018 to July 2019 were included in this study, and serum SERCA2a concentrations were measured; each enrolled patient was followed up by telephone after 6 months (6 ± 1 months) for general post-discharge patient status. The correlation between serum SERCA2a levels and the occurrence of adverse events (death or readmission due to heart failure) after hospital discharge was assessed using multiple analysis and trend analysis. Seventy-one patients with heart failure were finally included in this study, of whom 38 (53.5%) were men and 33 (46.5%) were women (All were postmenopausal women). Multiple analysis revealed no correlation between serum SERCA2a levels and the occurrence of adverse events in the total study population and in male patients, but serum SERCA2a levels were associated with the occurrence of adverse outcome events after hospital discharge in female patients (OR = 1.02, P = .047). Further analysis using a trend analysis yielded a 4.0% increase in the risk of adverse outcomes after hospital discharge for each unit increase in SERCA2a in female patients (OR = 1.04; P = .02), while no significant difference was seen in men. This study suggests that serum SERCA2a levels at admission are associated with the occurrence of post-discharge adverse events in postmenopausal female patients hospitalized with heart failure.

Global, regional and national temporal trends in prevalence for cardiovascular diseases in women of childbearing age, from 1990 to 2019: An age-period-cohort analysis

Background

Epidemiological studies on cardiovascular diseases (CVD) among women of childbearing age (WCBA) remain scarce. Our research aims to delineate the prevalence trends of CVD within this population over the past three decades, considering age, period, and birth cohort dynamics.

Methods

Estimates of CVD prevalence for WCBA, along with their 95% uncertainty intervals (UI), were extracted from the Global Burden of Diseases 2019 (GBD2019). An age-period-cohort (APC) model was utilized to assess the annual percentage change (net drifts) in overall prevalence, annual percentage changes in prevalence for individual age groups (local drifts), and fitted longitudinal age-specific rates adjusted for age effects and period/cohort relative risks (period/cohort effect).

Results

In 2019, the global prevalence of CVD among WCBA was 53.42 million (95% UI: 47.77 to 60.18). Eight countries recorded a prevalence exceeding one million, accounting for 54.17% of the global CVD prevalence in WCBA. Over the past 30 years, the annual net drift in CVD prevalence among the global WCBA was 0.27% (95% CI: 0.25 to 0.29). This value was 0.01% (95% CI: 0.04 to 0.06) in regions with a high sociodemographic index (SDI) and 0.21% (95% CI: 0.19 to 0.22) in those with a low SDI. Seventy-seven countries demonstrated an increasing trend in CVD prevalence, while 53 showed a decrease, and 74 remained relatively stable. Notably, as shown in local drift, there was a rise in CVD prevalence among adolescents aged 15-19 and adults aged 40-49 in regions categorized by five distinct SDI levels. This drift varied by SDI regions. Regions with a high SDI consistently had elevated period risks throughout the study duration, while other regions had lower period risks until 2000-2004 and displayed increased adverse period risks. The prevalence in low-middle and low SDI regions manifested detrimental trends, whereas other regions demonstrated an initial decline followed by a surge in successive birth cohorts.

Conclusions

Resources dedicated to CVD care for WCBA are largely insufficient, especially in low SDI regions. Thus, there is an urgent need to allocate cardiovascular healthcare resources variably across different SDI regions, aiming to diminish risks among successively younger birth cohorts. Throughout this endeavor, the formulation of targeted policies and the judicious distribution of resources are essential to reduce risks for women across all age groups.

Sex-Specific Cardiac Remodeling in Aged Rats after Early-Life Chronic Stress: Associations with Endocrine and Metabolic Factors

Background

Cardiovascular disease is a leading cause of death worldwide. Rates of cardiovascular disease vary both across the lifespan and between sexes. While multiple factors, including adverse life experiences, impact the development and progression of cardiovascular disease, the potential interactions of biological sex and stress history on the aged heart are unknown. To this end, we examined sex- and stress-specific impacts on left ventricular hypertrophy (VH) after aging. We hypothesized that early life chronic stress exposure impacts behavioral and physiologic responses that predict cardiac remodeling in a sex-specific manner.

Methods

Histological analysis was conducted on hearts of male and female rats previously exposed to chronic variable stress during the late adolescent period (postnatal days 43-62). These animals were challenged with a forced swim test and a glucose tolerance test before aging to 15 months and again being challenged. Predictive analyses were then used to isolate factors that relate to cardiac remodeling among these groups.

Results

Early-life chronic stress impacted cardiac remodeling in a sex-specific manner. Among rats with a history of chronic stress, females had increased inward VH. However, there were few associations within the female groups among individual behavioral and physiologic parameters and cardiac remodeling. While males as a group did not have VH after chronic stress, they exhibited multiple individual associations with cardiac susceptibility. Passive coping in young males and active coping in aged males related to VH in a stress history-dependent manner. Moreover, baseline corticosterone positively correlated with VH in unstressed males, while chronically-stressed males had positive correlations between VH and visceral adiposity.

Conclusions

These results indicate that females as a group are uniquely susceptible to the effects of early-life stress on cardiac remodeling later in life. Conversely, males have more individual differences in vulnerability, where susceptibility to cardiac remodeling relates to endocrine, metabolic, and behavioral measures depending on stress history. These results ultimately support a framework for accessing cardiovascular risk based on biological sex and prior adverse experiences.

Italian Association of Hospital Cardiologists Position Paper 'Gender discrepancy: time to implement gender-based clinical management'

It has been well assessed that women have been widely under-represented in cardiovascular clinical trials. Moreover, a significant discrepancy in pharmacological and interventional strategies has been reported. Therefore, poor outcomes and more significant mortality have been shown in many diseases. Pharmacokinetic and pharmacodynamic differences in drug metabolism have also been described so that effectiveness could be different according to sex. However, awareness about the gender gap remains too scarce. Consequently, gender-specific guidelines are lacking, and the need for a sex-specific approach has become more evident in the last few years. This paper aims to evaluate different therapeutic approaches to managing the most common women's diseases.

Epicardial fat and insulin resistance in healthy older adults: a cross-sectional analysis

Insulin resistance (IR) and cardiovascular diseases (CVD) are relevant concerns in the elderly population; as the world's population ages, IR and CVD are two universal public health problems. While a link between IR a CVD has been established, the mediating mechanisms are uncertain and rigorous investigations are needed to fully elucidate them. The study aimed at assessing the relationship between epicardial fat (EF), an indicator of cardiovascular risk, and IR in Italian free-living elderly (n = 89). Baseline data from a previous cohort was used. Anthropometric measurements, EF, and IR-related variables, including the HOMA-IR index and other biochemical parameters were obtained. The correlation between EF and IR was explored. Further analysis was conducted to identify significant differences regarding IR variables among EF quartiles. EF correlated positively with glucose levels in females, males and the total population. The pairwise comparison among EF quartiles showed significant differences in glucose levels, HOMA-IR index, triglycerides, and total cholesterol levels. To our knowledge, this is the only study assessing the relationship between EF and IR in healthy elderly, while most of the studies have investigated EF and IR in diseased populations. Further research with a longitudinal approach should be conducted to design concrete conclusions about this relationship.

Breastfeeding Practices in Patients with Heart Disease Stratified by Area Deprivation Index

Objective: We sought to evaluate breastfeeding (BF) practices in patients with maternal cardiac disease (MCD) stratified by area deprivation index (ADI) to identity communities at risk. Study Design: Retrospective cohort of patients managed by the University of Alabama at Birmingham (UAB) Cardio-Obstetrics Program. Patients were included if they had ≥1 prenatal visit with the Cardio-Obstetrics team, delivered at UAB, and had a street address on file. The primary outcome was BF rate at hospital discharge. Secondary outcomes included BF intent on admission and BF at the postpartum (PP) visit. ADI reports socioeconomic disadvantage at the census tract level; 1 = least deprived and 100 = most deprived. Baseline characteristics and BF rates were compared by ADI categories: Low (ADI 1-33), medium (ADI 34-66), and high (ADI 67-100). Results: One hundred and forty-eight patients were included: 14 (10%) low, 42 (28%) medium, and 92 (62%) high ADI. Patients in the high ADI category were younger relative to those in the medium or low ADI (26 versus 28 versus 32 years; p < 0.01) and less likely to be married or living with a partner (30.4% versus 58.5% versus 71.4%; p < 0.01), There was no difference in BF intent between the lowest, medium, and highest ADI categories (85.7% versus 85.4% versus 81.6%; p = 0.38) or BF rates at hospital discharge (100% versus 92.7% versus 85.6%, p = 0.23). However, there was a significant difference in BF rates at the PP visit (90% versus 63.0% versus 38.6%; p < 0.01) even after controlling for differences in baseline characteristics (odds ratio = 0.11 (95% confidence interval [0.01-0.93]), p = 0.043). Conclusions: There was an association between living in a resource-poor community and early cessation of BF in our population of patients with MCD. Community-based interventions targeting mothers with heart disease living in high ADI communities may help these individuals achieve higher BF rates.

Sex Differences in Diagnosis, Treatment, and Cardiovascular Outcomes in Homozygous Familial Hypercholesterolemia

Importance

Homozygous familial hypercholesterolemia (HoFH) is a rare genetic condition characterized by extremely increased low-density lipoprotein (LDL) cholesterol levels and premature atherosclerotic cardiovascular disease (ASCVD). Heterozygous familial hypercholesterolemia (HeFH) is more common than HoFH, and women with HeFH are diagnosed later and undertreated compared to men; it is unknown whether these sex differences also apply to HoFH.

Objective

To investigate sex differences in age at diagnosis, risk factors, lipid-lowering treatment, and ASCVD morbidity and mortality in patients with HoFH.

Design, Setting, and Participants

Sex-specific analyses for this retrospective cohort study were performed using data from the HoFH International Clinical Collaborators (HICC) registry, the largest global dataset of patients with HoFH, spanning 88 institutions across 38 countries. Patients with HoFH who were alive during or after 2010 were eligible for inclusion. Data entry occurred between February 2016 and December 2020. Data were analyzed from June 2022 to June 2023.

Main Outcomes and Measures

Comparison between women and men with HoFH regarding age at diagnosis, presence of risk factors, lipid-lowering treatment, prevalence, and onset and incidence of ASCVD morbidity (myocardial infarction [MI], aortic stenosis, and combined ASCVD outcomes) and mortality.

Results

Data from 389 women and 362 men with HoFH from 38 countries were included. Women and men had similar age at diagnosis (median [IQR], 13 [6-26] years vs 11 [5-27] years, respectively), untreated LDL cholesterol levels (mean [SD], 579 [203] vs 596 [186] mg/dL, respectively), and cardiovascular risk factor prevalence, except smoking (38 of 266 women [14.3%] vs 59 of 217 men [27.2%], respectively). Prevalence of MI was lower in women (31 of 389 [8.0%]) than men (59 of 362 [16.3%]), but age at first MI was similar (mean [SD], 39 [13] years in women vs 38 [13] years in men). Treated LDL cholesterol levels and lipid-lowering therapy were similar in both sexes, in particular statins (248 of 276 women [89.9%] vs 235 of 258 men [91.1%]) and lipoprotein apheresis (115 of 317 women [36.3%] vs 118 of 304 men [38.8%]). Sixteen years after HoFH diagnosis, women had statistically significant lower cumulative incidence of MI (5.0% in women vs 13.7% in men; subdistribution hazard ratio [SHR], 0.37; 95% CI, 0.21-0.66) and nonsignificantly lower all-cause mortality (3.0% in women vs 4.1% in men; HR, 0.76; 95% CI, 0.40-1.45) and cardiovascular mortality (2.6% in women vs 4.1% in men; SHR, 0.87; 95% CI, 0.44-1.75).

Conclusions and Relevance

In this cohort study of individuals with known HoFH, MI was higher in men compared with women yet age at diagnosis and at first ASCVD event were similar. These findings suggest that early diagnosis and treatment are important in attenuating the excessive cardiovascular risk in both sexes.

Cardiovascular multimodality imaging in women: a scientific statement of the European Association of Cardiovascular Imaging of the European Society of Cardiology

Cardiovascular diseases (CVD) represent an important cause of mortality and morbidity in women. It is now recognized that there are sex differences regarding the prevalence and the clinical significance of the traditional cardiovascular (CV) risk factors as well as the pathology underlying a range of CVDs. Unfortunately, women have been under-represented in most CVD imaging studies and trials regarding diagnosis, prognosis, and therapeutics. There is therefore a clear need for further investigation of how CVD affects women along their life span. Multimodality CV imaging plays a key role in the diagnosis of CVD in women as well as in prognosis, decision-making, and monitoring of therapeutics and interventions. However, multimodality imaging in women requires specific consideration given the differences in CVD between the sexes. These differences relate to physiological changes that only women experience (e.g. pregnancy and menopause) as well as variation in the underlying pathophysiology of CVD and also differences in the prevalence of certain conditions such as connective tissue disorders, Takotsubo, and spontaneous coronary artery dissection, which are all more common in women. This scientific statement on CV multimodality in women, an initiative of the European Association of Cardiovascular Imaging of the European Society of Cardiology, reviews the role of multimodality CV imaging in the diagnosis, management, and risk stratification of CVD, as well as highlights important gaps in our knowledge that require further investigation.
