Hypertension Across a Woman's Life Cycle

Genetics of hypertension-related sex differences and hypertensive disorders of pregnancy

Background: Hypertension and hypertensive disorders of pregnancy (HDP) cause a significant burden of disease on societies and individuals by increasing cardiovascular disease risk. Environmental risk factors alone do not explain the observed sexual dimorphism in lifetime blood pressure (BP) trajectories nor inter-individual variation in HDP risk.

Methods: In this short review, we focus on the genetics of hypertension-related sex differences and HDP and discuss the importance of genetics utilization for sex-specific hypertension risk prediction.

Results: Population and twin studies estimate that 28-66% of variation in BP levels and HDP is explained by genetic variation, while genomic wide association studies suggest that BP traits and HDP partly share a common genetic background. Moreover, environmental and epigenetic regulation of these genes differ by sex and oestrogen receptors in particular are shown to convey cardio- and vasculoprotective effects through epigenetic regulation of DNA. The majority of known genetic variation in hypertension and HDP is polygenic. Polygenic risk scores for BP display stronger associations with hypertension risk in women than in men and are associated with sex-specific age of hypertension onset. Monogenic forms of hypertension are rare and mostly present equally in both sexes.

Conclusion: Despite recent genetic discoveries providing new insights into HDP and sex differences in BP traits, further research is needed to elucidate the underlying biology. Emphasis should be placed on demonstrating the added clinical value of these genetic discoveries, which may eventually facilitate genomics-based personalized treatments for hypertension and HDP.

2024 Latin American Society of Hypertension guidelines on the management of arterial hypertension and related comorbidities in Latin America

ABSTRACT

Hypertension is responsible for more than two million deaths due to cardiovascular disease annually in Latin America (LATAM), of which one million occurs before 70 years of age. Hypertension is the main risk factor for cardiovascular morbidity and mortality, affecting between 20 and 40% of LATAM adults. Since the publication of the 2017 LASH hypertension guidelines, reports from different LATAM countries have confirmed the burden of hypertension on cardiovascular disease events and mortality in the region. Many studies in the region have reported and emphasized the dramatically insufficient blood pressure control. The extremely low rates of awareness, treatment, and control of hypertension, particularly in patients with metabolic disorders, is a recognized severe problem in LATAM. Earlier implementation of antihypertensive interventions and management of all cardiovascular risk factors is the recognized best strategy to improve the natural history of cardiovascular disease in LATAM. The 2024 LASH guidelines have been developed by a large group of experts from internal medicine, cardiology, nephrology, endocrinology, general medicine, geriatrics, pharmacology, and epidemiology of different countries of LATAM and Europe. A careful search for novel studies on hypertension and related diseases in LATAM, together with the new evidence that emerged since the 2017 LASH guidelines, support all statements and recommendations. This update aims to provide clear, concise, accessible, and useful recommendations for health professionals to improve awareness, treatment, and control of hypertension and associated cardiovascular risk factors in the region.

Differences in sex and age response to single pill combination based antihypertensive therapy reflecting in blood pressure and arterial stiffness

OBJECTIVE

There are noticeable sex differences in the treatment response to antihypertensives, with limited data on the response to single pill combinations. The aim of the PRECIOUS trial was to assess the treatment response to perindopril/amlodipine and perindopril/amlodipine/indapamide dual and triple single-pill combination in men and women.

METHODS

Four hundred and forty adults with essential hypertension were assessed in the 16-week interventional, open-label, prospective, international, multicentre trial. Based on the previous antihypertensive therapy, patients were assigned to either perindopril/amlodipine 4/5 mg or perindopril/amlodipine/indapamide 4/5/1.25 mg, with the initial dose up-titrated in 4-week intervals in case of uncontrolled blood pressure. An additional analysis was performed for sex- and age-related differences on the blood pressure response and arterial stiffness in men and women aged 35-74 years.

RESULTS

Women achieved better overall blood pressure control in all age groups, except for the 35-44 age group. Women presented higher average 24 h aortic augmentation indexes than men, but had more pronounced decreasing trends. The pulse wave velocity was only age-dependent, with reductions slightly greater in women. Both the aortic augmentation index and pulse wave velocity were significantly decreased in all groups compared to baseline.

CONCLUSIONS

The results of the PRECIOUS trial contribute significant data to the expanding body of evidence on sex differences in hypertension, including the aspect of age-related changes during the life course of women. The differences between same-aged men and women tend to be smaller with advancing age, but with a greater treatment response in women in all age groups for all observed blood pressure parameters and arterial stiffness.

Estrogen Receptor Beta Agonist Influences Presynaptic NMDA Receptor Distribution in the Paraventricular Hypothalamic Nucleus Following Hypertension in a Mouse Model of Perimenopause

Women become susceptible to hypertension as they transition to menopause (i.e., perimenopause); however, the underlying mechanisms are unclear. Animal studies using an accelerated ovarian failure (AOF) model of peri-menopause (peri-AOF) demonstrate that peri-AOF hypertension is associated with increased postsynaptic NMDA receptor plasticity in the paraventricular hypothalamic nucleus (PVN), a brain area critical for blood pressure regulation. However, recent evidence indicates that presynaptic NMDA receptors also play a role in neural plasticity. Here, using immuno-electron microscopy, we examine the influence of peri-AOF hypertension on the subcellular distribution of the essential NMDA GluN1 receptor subunit in PVN axon terminals in peri-AOF and in male mice. Hypertension was produced by 14-day slow-pressor angiotensin II (AngII) infusion. The involvement of estrogen signaling was investigated by co-administering an estrogen receptor beta (ERß) agonist. Although AngII induced hypertension in both peri-AOF and male mice, peri-AOF females showed higher cytoplasmic GluN1 levels. In peri-AOF females, activation of ERß blocked hypertension and increased plasmalemmal GluN1 in axon terminals. In contrast, stimulation of ERß did not inhibit hypertension or influence presynaptic GluN1 localization in males. These results indicate that sex-dependent recruitment of presynaptic NMDA receptors in the PVN is influenced by ERß signaling in mice during early ovarian failure.

Adherence to guideline-recommended care of late-onset hypertension in females versus males: A population-based cohort study

BACKGROUND

Sex-based disparities in cardiovascular outcomes may be improved with appropriate hypertension management.

OBJECTIVE

To compare the evidence-based evaluation and management of females with late-onset hypertension compared to males in the contemporary era.

METHODS

Design: Retrospective population-based cohort study.

SETTING

Ontario, Canada.

PARTICIPANTS

Residents aged ≥66 years with newly diagnosed hypertension between January 1, 2010, and December 31, 2017.

EXPOSURE

Sex (female vs. male).

OUTCOMES AND MEASURES

We used Poisson and logistic regression to estimate adjusted sex-attributable differences in the performance of guideline-recommended lab investigations. We estimated adjusted differences in time to the prescription of, and type of, first antihypertensive medication prescribed between females and males, using Cox regression.

RESULTS

Among 111,410 adults (mean age 73 years, 53% female, median follow-up 6.8 years), females underwent a similar number of guideline-recommended investigations (adjusted incidence rate ratio, 0.997 [95% confidence interval [CI] 0.99-1.002]) compared to males. Females were also as likely to complete all investigations (0.70% females, 0.77% males; adjusted odds ratio, 0.96 [95% CI 0.83-1.11]). Females were slightly less likely to be prescribed medication (adjusted hazard ratio [aHR] 0.98 [95% CI 0.96-0.99]) or, among those prescribed, less likely to be prescribed first-line medication (aHR, 0.995 [95% CI 0.994-0.997]).

CONCLUSIONS

Compared to males, females with late-onset hypertension were equally likely to complete initial investigations with comparable prescription rates. These findings suggest that there may be no clinically meaningful sex-based differences in the initial management of late-onset hypertension to explain sex-based disparities in cardiovascular outcomes.

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.

The Pathophysiology, Prognosis and Treatment of Hypertension in Females from Pregnancy to Post-menopause: A Review

PURPOSE OF REVIEW

We summarise the physiological changes and risk factors for hypertension in females, potential sex-specific management approaches, and long-term prognosis.

KEY FINDINGS

Pregnancy and menopause are two key phases of the life cycle where females undergo significant biological and physical changes, making them more prone to developing hypertension. Gestational hypertension occurs from changes in maternal cardiac output, kidney function, metabolism, or placental vasculature, with one in ten experiencing pregnancy complications such as intrauterine growth restriction and delivery complications such as premature birth. Post-menopausal hypertension occurs as the protective effects of oestrogen are reduced and the sympathetic nervous system becomes over-activated with ageing. Increasing evidence suggests that post-menopausal females with high blood pressure (BP) experience greater risk of cardiovascular events at lower BP thresholds, and greater vulnerability to treatment-related adverse effects. Hypertension is a key risk factor for cardiovascular disease in females. Current BP treatment guidelines and recommendations are similar for both sexes, without addressing sex-specific factors. Future investigations into ideal diagnostic thresholds, BP control targets and treatment regimens in females are needed.

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.

Antihypertensive utilization patterns among pregnant persons with pre-existing hypertension in the US: A population-based study

BACKGROUND

Hypertension among persons with childbearing potential is on the rise. Maintaining proper blood pressure during pregnancy is vital to prevent maternal and neonatal complications. Yet, limited evidence on the risk-benefit of various antihypertensives presents challenges for informed decision-making during this critical period. This study aimed to examine the utilization patterns of different classes of antihypertensives among persons with pre-existing hypertension before, during, and after pregnancy.

METHODS

We used MarketScan® Commercial Database 2011-2020 to analyze antihypertensive utilization among pregnant persons aged 12 to 55 identified via a validated algorithm. Pre-existing hypertension was defined as ≥1 inpatient or ≥2 outpatient encounters for hypertension within the 180 days preceding the LMP. Antihypertensive utilization was described during target periods: 0-3 months (0-3M) before pregnancy, 1st/2nd/3rd trimester (T1/2/3), 0-3M, and 4-6M after pregnancy.

RESULTS

We identified 1,950,292 pregnancies, of which 20,576 (12,978 live and 7,598 non-live) had pre-existing hypertension. Both groups had similar antihypertensive use (80.1% and 81.0%, respectively) during the 6 months before pregnancy (baseline). For live-birth pregnancies, 13.9% of baseline users discontinued treatment during pregnancy, while 28.9% of non-users initiated antihypertensives during pregnancy, and 17.2% started postpartum. Before pregnancy, the predominant antihypertensives included thiazide diuretics (21.9%), combined α- and β-blockers (18.4%), and dihydropyridines (16.2%). During pregnancy, thiazide diuretics, cardioselective β-blockers, and ACE inhibitors declined (T3: 3.0%, 4.2%, and 0.8%). Dihydropyridine use was steady during pregnancy, but preference shifted from amlodipine to nifedipine in T3 (2.2.% vs.10.8%). Central α2-agonists increased during pregnancy (up to 15.2% in T3) compared to both pre- (9.8%) and post-pregnancy (5.7%). ARBs mirrored ACE inhibitors, with less than 1% utilization in later trimesters. Combination agents dropped from 10.8% pre-pregnancy to 0.8% in T3, then rebounded to 7.3% post-pregnancy.

CONCLUSION

Research is warranted to evaluate the choice of antihypertensives and optimal timing to switch to safer alternatives, considering maternal and fetal outcomes.

Sex-Related Disparities in Cardiovascular Outcomes Among Older Adults With Late-Onset Hypertension

BACKGROUND

It is unclear whether sex-based differences in cardiovascular outcomes exist in late-onset hypertension.

METHODS

This is a population-based cohort study in Ontario, Canada of 266 273 adults, aged ≥66 years with newly diagnosed hypertension. We determined the incidence of the primary composite cardiovascular outcome (myocardial infarction, stroke, and congestive heart failure), all-cause mortality, and cardiovascular death by sex using Cox proportional hazard models adjusted for demographic factors and comorbidities.

RESULTS

The mean age of the total cohort was 74 years, and 135 531 (51%) were female. Over a median follow-up of 6.6 (4.7-9.0) years, females experienced a lower crude incidence rate (per 1000 person-years) than males for the primary composite cardiovascular outcome (287.3 versus 311.7), death (238.4 versus 251.4), and cardiovascular death (395.7 versus 439.6), P<0.001. The risk of primary composite cardiovascular outcome was lower among females (adjusted hazard ratio, 0.75 [95% CI, 0.73-0.76]; P<0.001) than in males. This was consistent after adjusting for the competing risk of all-cause death with a subdistributional hazard ratio, 0.88 ([95% CI, 0.86-0.91]; P<0.001).

CONCLUSIONS

Females had a lower risk of cardiovascular outcomes compared with males within a population characterized by advanced age and new hypertension. Our results highlight that the severity of outcomes is influenced by sex in relation to the age at which hypertension is diagnosed. Further studies are required to identify sex-specific variations in the diagnosis and management of late-onset hypertension due to its high incidence in this group.

Resistance training effects on healthy postmenopausal women: a systematic review with meta-analysis

The aim of this systematic review with meta-analysis was to evaluate the effects of resistance training on physical fitness, physiological variables and body composition of postmenopausal women. The present systematic review was performed in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement and was registered in PROSPERO. A total of 12 studies were included. The literature search was performed in PubMed, Web of Science and EBSCO. Randomized control trials were included. Two blinded investigators performed the search, study selection and data collection, and assessed the quality and risk of bias. A random-effects model was used for all analyses. Compared to the control group, resistance training produced a significant improvement in maximal oxygen volume (standardized mean difference [SMD] = 2.32, p < 0.001), lower extremity strength (SMD = 4.70, p < 0.001) and upper extremity strength (SMD = 7.42, p < 0.001). The results obtained in the systematic review and meta-analysis confirm the benefits of resistance training on physical fitness in postmenopausal women, although there is more debate regarding its influence on bone mineral density, and anthropometric and derived variables. This work provides a solid starting point for promoting resistance training at a frequency of 3 days per week, in 60-min sessions, with the aim of improving parameters directly related to quality of life, functionality and disease prevention of postmenopausal women.

The Cardiovascular Risk Awareness and Health Lifestyle of Italian Women

Background: Cardiovascular (CV) disease is the leading cause of death in women, but few of them are aware of the CV risks (CVRs). Most women are not aware of all the CV risk factorsand their knowledge often still does not improve their lifestyle. Methods: The Carin Women is a survey conducted among Italian women by filling out a questionnaire in the waiting rooms of clinics. The aim was to determine the level of awareness of women's cardiovascular risk, knowledge of risk factors, and lifestyle. A total of 5590 questionnaires were completed in two different periods. Results: Median age was 56 (IQR 46-65); BMI was 25 (IQR 22-29). Schooling, marital status, and rate of risk conditions were assessed; 311 women (5.57%) had already suffered a cardiovascular event. The relationship between the CV events and the number of traditional risk factors was significant. A similar curve, but without significant differences, was reported for non-traditional risk factors. From the total number of women, 23% with a high CVR and 62% with a very high CVR underestimated thei risk regardless of their level of education. Up to 43% of women underestimated female CV risk compared to male risk. Women showed a good knowledge of traditional risk factors, but only a few of them had a healthy lifestyle: 21.86% were smokers, only 45.88% performed sufficient physical activity, 27.55% did not recognize they were overweight, and only 30.4% consumed more than two daily portions of fruit and vegetables. Most women (86%) need more information about CVR. Conclusions: Italian women underestimate female CVRs and their own CVR.

Population analysis of ischemic stroke burden and risk factors in the United States in the pre- and post-mechanical thrombectomy eras

OBJECTIVES

To provide an updated analysis of the burden of ischemic stroke in the United States.

MATERIALS AND METHODS

Using the Global Burden of Disease database, we estimated age-standardized, population-adjusted rates of incidence, prevalence, mortality, and disability-adjusted life years from 2010 to 2019, with regional comparisons. Deaths and disability-adjusted life years were compared in 2010-2014 and 2015-2019 to assess the potential effect of increased mechanical thrombectomy use. The attributable, disability-adjusted life years for twenty risk factors were estimated, ranked, and trended.

RESULTS

Incident ischemic strokes decreased by 11.4 % across the study period from 65.7 (55.9-77.3) to 58.2 (49.0-69.5) per 100,000. Prevalence (-8.2 %), mortality (-1.9 %), and disability-adjusted life years (-4.4 %) all declined. All regions showed reductions in all burden measures, with the South consistently having the highest burden yet the largest reduction in incidence (-12.6 %) and prevalence (-10.5 %). Deaths (p < 0.0001) and DALYs (p < 0.0001) significantly differed between the pre- and post-mechanical thrombectomy eras. Total attributable disability-adjusted life years for all risk factors decreased from 304.7 (258.5-353.2) in 2010 to 288.9 (242.2-337.2) in 2019. In 2019, the risk factors with the most disability-adjusted life years were hypertension, hyperglycemia, and obesity with no state-based differences. Across the study period, disability-adjusted life years attributable to leading risk factors decreased among men but decreased less or increased among women.

CONCLUSIONS

The burden of ischemic stroke decreased during the study period. Declines in deaths and disability-adjusted life years suggest a mitigating impact of mechanical thrombectomy. While disability-adjusted life years attributable to leading risk factors decreased, sex-based disparities were observed.

Combined cardiovascular effects of ovariectomy and high-intensity interval training in female spontaneously hypertensive rats

Hypertensive postmenopausal women are more likely to develop adverse cardiac remodeling and respond less effectively to drug treatment than men. High-intensity interval exercise (HIIE) is a nonpharmacological strategy for the treatment of hypertension; however, the effectiveness in women remains uncertain. This study was designed to evaluate 1) the effects of HIIE training upon morphological and functional markers of cardiovascular health in female SHR and 2) to determine whether the hormonal shift induced by ovariectomy could influence cardiovascular responses to HIIE. Thirty-six SHR were randomly assigned to four groups: ovariectomized sedentary, ovariectomized trained, sham-operated sedentary, and sham-operated trained. The trained rats performed HIIE 5 days/wk for 8 wk. Blood pressure and echocardiographic measurements were performed before and after training in animals. Cardiac response to β-adrenergic stimulation and the expression of calcium regulatory proteins and estrogen receptors in heart samples were assessed. Endothelium-dependent vasorelaxation in response to acetylcholine was evaluated in aortic rings as well as the expression of nitric oxide synthase isoforms (eNOS and P-eNOS) by Western blotting. In both groups of trained SHR, HIIE induced eccentric cardiac remodeling with greater inotropic and chronotropic effects, as well as an increase in SERCA and β1AR expression. However, although the trained rats showed improved endothelial function and expression of eNOS and P-eNOS in the aorta, there was no demonstrated effect on blood pressure. In addition, the responses to HIIE training were not affected by ovariectomy. This work highlights the importance of assessing the cardiovascular efficacy and safety of different exercise modalities in women.NEW & NOTEWORTHY This study reports the effects of high-intensity interval exercise (HIIE) training on cardiac and endothelial function in female hypertensive rats. Despite a lack of effect on blood pressure (BP), HIIE training induces eccentric cardiac remodeling with greater functionals effects. Furthermore, training has beneficial effects on endothelial function. However, ovarian hormones do not seem to modulate cardiac and aortic adaptations to this training modality. All this underlines the need to consider training modalities on the cardiovascular system in women.

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.

Understanding the spectrum of cardiovascular risk in women - A primer for prevention

Cardiovascular disease (CVD) is the leading cause of death in women worldwide and the lifetime risk of CVD in women is similar to men. However, the pathophysiology of CVD varies between women and men necessitating a sex-specific understanding of cardiovascular (CV) risk. A belief that women have a lower CVD risk than men, and an underrepresentation in clinical research for many years has led to a paucity of evidence in the prevention and management of CVD in women. Many recent efforts have tried to bridge the gap. As a result, we now know that traditional risk factors impact CVD risk differently in women when compared with men. There are also numerous sex-specific and pregnancy related risk factors that modify the risk and can predict the future development of CVD in women. This is important as risk calculators, in general, tend to misclassify risk in young women with nontraditional CVD risk factors. To address this, guidelines have introduced the concept of risk enhancers that can suggest a higher risk. The use of coronary artery calcium score can further accurately delineate risk in these women, leading to an appropriate matching of therapy to underlying risk. This review discusses implementation strategies that are essential to mitigate disparities in CVD outcomes and optimizing CVD risk in women.

Blood Pressure Control and Maintenance in a Prospective Cohort of Younger Veterans: Roles of Sex, Race, Ethnicity, and Social Determinants of Health

Background

Proactive blood pressure (BP) management is particularly beneficial for younger Veterans, who have a greater prevalence and earlier onset of cardiovascular disease than non-Veterans. It is unknown what proportion of younger Veterans achieve and maintain BP control after hypertension onset and if BP control differs by demographics and social deprivation.

Methods

Electronic health records were merged from Veterans who enrolled in VA care 10/1/2001-9/30/2017 and met criteria for hypertension - first diagnosis or antihypertensive fill. BP control (140/90 mmHg), was estimated 1, 2, and 5 years post-hypertension documentation, and characterized by sex, race, and ethnicity. Adjusted logistic regressions assessed likelihood of BP control by these demographics and with the Social Deprivation Index (SDI).

Results

Overall, 17% patients met criteria for hypertension (n=198,367; 11% of women, median age 41). One year later, 59% of men and 65% of women achieved BP control. After adjustment, women had a 72% greater odds of BP control than men, with minimal change over 5 years. Black adults had a 22% lower odds of BP control than White adults. SDI did not significantly change these results.

Conclusions

In the largest study of hypertension in younger Veterans, 41% of men and 35% of women did not have BP control after 1 year, and BP control was consistently better for women through 5 years. Thus, the first year of hypertension management portends future, long-term BP control. As social deprivation did not affect BP control, the VA system may protect against disadvantages observed in the general U.S. population.

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.

Exercise testing unmasks exaggerated blood pressure independent of fibrinolytic response in Black but not White postmenopausal females

Exercise testing unmasks more exaggerated systolic blood pressure responses (SBP) in Black compared with White male adults. Such responses, if translatable to females, may detect racial disparities particularly relevant during menopause. Given the endothelial involvement in BP regulation and as a source of fibrinolytic markers, it follows that fibrinolytic and BP response to exercise could be linked. Thus, we examined BP and fibrinolytic responses to exercise testing in Black and White postmenopausal females. Postmenopausal females (Black = 40; White = 41; 51-70 yr) performed maximal treadmill exercise. BP and blood draws were conducted before and immediately after exercise. Plasma samples, using minimal stasis, were analyzed for tissue plasminogen activator (tPA) and plasminogen activator inhibitor 1 (PAI-1) activity and antigen, respectively. Resting SBP and fibrinolytic potential were similar between races. Black females exhibited greater increases in SBP during exercise [change (d)=75, 95% CI: 64-86 mmHg, P < 0.001] than White females (d = 60, 95% CI: 48-71 mmHg, P < 0.001). Black compared with White females had smaller changes in tPA (d = 3.27, 95% CI: 2.28-4.27 IU/mL, P < 0.001 vs. d = 5.55, 95% CI: 4.58-6.53, P < 0.001) and PAI-1 (d = -2.89, 95% CI: -4.39 to -1.40 IU/mL, P < 0.001 vs. d = -5.08, 95% CI: -6.59 to -3.61, P < 0.001) activities after exercise. SBP exercise-induced changes were not associated with tPA (r = -0.10, P = 0.42) or PAI-1 (r = 0.13, P = 0.30), without any influence of race (P > 0.05). Our findings show that maximal exercise unmasks risk factors for cardiovascular disease in Black postmenopausal females.NEW & NOTEWORTHY Exaggerated SBP responses to exercise testing are more frequent in Black than in White male adults. Such responses, if translatable to females, may detect early racial disparities arriving during menopause. Because the endothelium regulates BP and fibrinolytic responses, these could be linked during exercise. At peak exercise, Black but not White postmenopausal females had more exaggerated SPB responses regardless of reduced fibrinolytic potential. Maximal exercise unmasked risk factors for cardiovascular disease in Black postmenopausal females.

Effect of exercise modalities on postexercise hypotension in pre- and postmenopausal women: a systematic review and meta-analysis

Hormonal changes associated with menopause increase the risk of hypertension. Postexercise hypotension (PEH) is an important tool in the prevention and management of hypertension; however, menopause may alter this response. The aim of this systematic review and meta-analysis [International Prospective Registered of Systematic Review (PROSPERO): CRD42023297557] was to evaluate the effect of exercise modalities (aerobic, AE; resistance, RE; and combined exercise, CE: AE + RE) on PEH in women, according to their menopausal status (premenopausal or postmenopausal). We searched controlled trials in PubMed, Web of Science, EBSCO, and Science Direct published between 1990 and March 2023. Inclusion criteria were normotensive, pre- and hypertensive, pre- and postmenopausal women who performed an exercise session compared with a control session and reported systolic blood pressure (SBP) and diastolic blood pressure (DBP) for at least 30 min after the sessions. Methodological quality was assessed using the PEDro scale. Standardized mean differences (Hedge's g) and their 95% confidence intervals (CIs) were calculated, and Q-test and Z-test were conducted to assess differences between moderators. Forty-one trials with 718 women (474 menopausal) were included. Overall, we found with moderate evidence that SBP and DBP decreased significantly after exercise session (SBP: g = -0.69, 95% CI -0.87 to -0.51; DBP: g = -0.31, 95% CI -0.47 to -0.14), with no difference between premenopausal and postmenopausal women. Regarding exercise modalities, RE is more effective than AE and CE in lowering blood pressure (BP) in women regardless of menopausal status. In conclusion, women's menopausal status does not influence the magnitude of PEH, and the best modality to reduce BP in women seems to be RE.NEW & NOTEWORTHY This meta-analysis has demonstrated that a single bout of exercise induces postexercise hypotension (PEH) in women and that the hormonal shift occurring with menopause does not influence the magnitude of PEH. However, we have shown with moderate evidence that the effectiveness of exercise modalities differs between pre- and postmenopausal women. Resistance and combined exercises are the best modalities to induce PEH in premenopausal women, whereas resistance and aerobic exercises are more effective in postmenopausal women.

Associations between hypertension with reproductive and menopausal factors: An integrated women's health programme (IWHP) study

BACKGROUND

Women are less likely to have classic cardiovascular risk factors than men, and events during their reproductive and menopausal years may increase hypertension risk. The aim of this study is to examine woman-specific factors, including menstrual, reproductive and pregnancy complications, in relation to the prevalence of hypertension in mid-life Asian women.

METHODS

This is a cross-sectional study of 1146 healthy women aged 45-69 years, from a multi-ethnic Asian cohort. The women completed an extensive questionnaire that included their sociodemographic details, medical history, lifestyle and physical activity, and reproductive and menopausal history. They also underwent objectively measured physical performance tests and a dual X-ray absorptiometry scan. Hypertension was defined as a systolic BP ≥140 and/or diastolic BP ≥90mm Hg, past diagnosis by a physician, or use of antihypertensive medications. Multivariable logistic regression was used to assess the independent risk factors for hypertension.

RESULTS

The average age of the 1146 women analysed was 56.3 (SD 6.2) years, and 55.2 percent of them were hypertensive. The prevalence of gestational diabetes and gestational hypertension was 12.6% and 9.4%, respectively. Besides age, abnormal menstrual cycle length at 25 years of age (OR:2.35, CI:1.34-4.13), preeclampsia (OR:2.46, CI:1.06-5.74), increased visceral adiposity (OR:4.21, CI:2.28-7.79) and reduced physical performance (OR:2.83, CI:1.46-5.47) were independently associated with hypertension in Asian women.

CONCLUSIONS

Our findings highlight the necessity of including features of menstrual and reproductive history as possible indicators of hypertension risk in cardiovascular disease risk assessment and prevention among Asian women. Reducing visceral adiposity and exercise to improve physical performance may help women avoid developing hypertension.

Sex Disparities in Cardiovascular Disease

Cardiovascular disease is the leading cause of death in women. It remains underdiagnosed, undertreated, and portends worse outcomes in women than men. Disparities exist in every stage of science, from bench research to the editorial board of major journals and in every cardiovascular subspecialty. This review summarizes differences in cardiovascular risk factors and disparities in management and outcomes of ischemic heart disease, heart failure, aortic stenosis, and atrial fibrillation. It also provides an overview of female representation as participants and leaders of clinical trials, editorial boards, and academic institutions. Strategies to overcome these disparities are proposed with examples of successful programs.

Biosocial predictors and blood pressure goal attainment among postmenopausal women with hypertension

Objectives

In postmenopausal states, women may not maintain blood pressure (BP) in the same way as men, even though most women follow their treatment plans and prescriptions more consistently than men. Biological and lifestyle factors influence the progression of hypertension in postmenopausal women (PMW). This study aimed to determine biosocial predictors associated with achieving the target BP in PMW with hypertension.

Methods

A prospective observational study was conducted in the General Medicine Department at Karuna Medical College Hospital, Kerala, India. The definition of BP goal attainment was established based on the guidelines outlined by the VIII Joint National Committee 2014 (JNC VIII). Multivariate logistic regression analysis was used to analyse biosocial predictors, such as educational status, employment status, body mass index (BMI), number of children, age at menarche, age at menopause, and number of co-morbidities, associated with BP goal achievement.

Results

Of the patients, 56.4% achieved their BP goals on monotherapy and 59.7% achieved it on combination therapy. Level of education [odds ratio (OR) = 1.275, 95% confidence interval (CI): 0.234-7.172], employment status (OR = 0.853, 95% CI: 0.400-1.819), age at menopause (OR = 1.106, 95% CI: 0.881-1.149), number of children (OR = 1.152, 95% CI: 0.771-1.720), BMI (OR = 0.998, 95% CI: 0.929-1.071), and number of co-morbidities (OR = 0.068, 95% CI: 0.088-1.093) did not show a significant relationship, and age at menarche (OR = 1.577, 95% CI: 1.031-2.412) showed a significant association with BP goal attainment among hypertensive postmenopausal women.

Conclusion

Half of the hypertensive postmenopausal women did not achieve their BP goals. Interventions are required to expand screening coverage and, under the direction of medical professionals, there should be plans to improve hypertension control and increase awareness of the condition.

Factors associated with non-treatment of hypertension and gender differences at baseline in the ELSA-Brasil cohort

The treatment of arterial hypertension (AH) contributes to the reduction of morbidity and mortality. Gender differences are likely to play a role, as non-treatment is associated with clinical and sociodemographic aspects. The aim of this study was to investigate the factors associated with non-treatment of AH and gender differences in hypertensive individuals from the ELSA-Brasil cohort. The study was conducted with 5,743 baseline hypertensive cohort participants. AH was considered if there was a previous diagnosis or if systolic blood pressure (SBP) was ≥140 and/or diastolic BP (DBP) was ≥90 mmHg. Sociodemographic and anthropometric data, lifestyle, comorbidities, and use of antihypertensive medications were evaluated through interviews and in-person measurements. Treatment with renin-angiotensin-aldosterone system inhibitors (RAASi) or other antihypertensive medications and non-treatment were evaluated with multivariate logistic regression. Non-treatment was observed in 32.8% of hypertensive individuals. Of the 67.7% treated individuals, 41.1% received RAASi. Non-treatment was associated with alcohol consumption in women (OR=1.41; 95%CI: 1.15-1.73; P=0.001), lowest schooling level in men (OR=1.70; 95%CI: 1.32-2.19; P<0.001), and younger age groups in men and women (strongest association in males aged 35-44 years: OR=4.58, 95%CI: 3.17-6.6, P<0.001). Among those using RAASi, a higher proportion of white, older individuals, and with more comorbidities was observed. The high percentage of non-treatment, even in this civil servant population, indicated the need to improve the treatment cascade for AH. Public health policies should consider giving special attention to gender roles in groups at higher risk of non-treatment to reduce inequities related to AH in Brazil.

Blood Pressure Trajectories Through the First Year Postpartum in Overweight or Obese Individuals Following a Hypertensive Disorder of Pregnancy

BACKGROUND

Hypertensive disorders of pregnancy are associated with cardiovascular disease; however, patterns of blood pressure (BP) recovery are understudied. We compared pregnancy and postpartum BP trajectories among individuals with hypertensive disorders of pregnancy who developed persistent hypertension at 1-year postpartum compared with individuals with normalization of BP.

METHODS

We used data from a randomized clinical trial of individuals with overweight, obesity, and hypertensive disorders of pregnancy conducted in the first year after delivery. Pregnancy BPs were obtained during prenatal visits; postpartum BPs were prospectively obtained through home monitoring. Demographic characteristics and trajectories were compared by hypertensive status (systolic BP ≥130 mm Hg, diastolic BP ≥80 mm Hg, or use of antihypertensive medications) at 1 year. We used repeated BP measures to fit separate mixed-effects linear regression models for pregnancy and postpartum using restricted cubic splines.

RESULTS

We included 129 individuals; 75 (58%) individuals progressed to hypertension by 1-year postpartum. Individuals with hypertension were older, delivered at earlier gestational ages, and had higher body mass index at 1-year postpartum compared with those with normalization. Individuals with hypertension had similar BP trajectories during pregnancy to those with BP normalization but a significantly different BP trajectory (P<0.01 for systolic and diastolic BPs) in the first year postpartum. These differences persisted in multivariable models after adjustment for early pregnancy body mass index, age, and severity of hypertensive disorder of pregnancy (P<0.01 for systolic and diastolic BPs).

CONCLUSIONS

BP trajectories in the first year postpartum, but not during pregnancy, may provide important information for risk stratification after a hypertensive disorder of pregnancy.

A disease of her own? Unique features of heart failure in women

Heart failure (HF) is a significant and growing public health challenge for women. Compared with men, women tend to develop HF later in life and are more likely to experience HF with preserved ejection fraction. There are also significant sex differences in outcomes, with women reporting lower quality of life but overall better survival versus men. In this review, we summarize sex differences in traditional HF risk factors, such as hypertension, diabetes, obesity and coronary artery disease, as well as female-specific HF risk factors including menopause, pregnancy and adverse pregnancy outcomes, and breast cancer therapy. While our understanding of the sex-specific efficacy of HF therapy remains limited by the underrepresentation of women in major clinical trials, there is a suggestion of preferential benefit of specific agents for women. Further work is required to better understand the pathophysiology of HF in women uniquely and to increase representation of women in clinical trials.

Understanding of and clinical approach to cardiometabolic transition at the menopause

Cardiovascular disease (CVD) represents the leading cause of death and accounts for almost 50% of all deaths in women worldwide. The menopausal transition is associated with central body fat accumulation, a decrease in energy expenditure, weight gain, insulin resistance and a pro-atherogenic lipid profile. Moreover, menopause is independently associated with an adverse effect on functional and structural indices of subclinical atherosclerosis. Women with premature ovarian insufficiency have heightened CVD risk compared to women of natural age at menopause. Furthermore, women with severe menopausal symptoms may have a more adverse cardiometabolic profile than those without symptoms. We reviewed the latest evidence on the cardiovascular management of perimenopausal or postmenopausal women. Clinicians should aim for cardiovascular risk stratification, followed by dietary and lifestyle advice as required based on individual needs. The medical management of cardiometabolic risk factors at midlife should always be individualized, focusing on hypertension, diabetes and dyslipidemia. Menopausal hormone therapy, when prescribed for the management of bothersome menopausal symptoms or for the prevention of osteoporosis, has also a beneficial effect on cardiometabolic risk factors. This narrative review aims to summarize the cardiometabolic alternations occurring during the menopausal transition and to outline the appropriate prevention strategies to prevent future cardiovascular adverse outcomes.

Diet Quality, Sedentary Time, and Blood Pressure in the POUCHmoms Study

BACKGROUND

Elevated blood pressure (BP) is a major contributor to cardiovascular disease in womens; diet and sedentary time (ST) are modifiable lifestyle factors thought to influence BP.

OBJECTIVES

The aim of this study was to examine 2 diet-quality measures and ST in relation to BP among parous womens.

METHODS

This cross-sectional analysis uses data from 677 womens (age 25-55 y) enrolled in the Pregnancy Outcomes and Community Health (POUCH) Study and followed up in the POUCHmoms study 7-15 y after delivery (2011 and 2014). Follow-up measures included a food-frequency questionnaire (FFQ), self-report of ST (occupational and leisure), and systolic and diastolic blood pressure (SBP and DBP, respectively). The FFQ was used to calculate 2 diet-quality measures, Alternative Healthy Eating Index-2010 (AHEI) and Dietary Approaches to Stop Hypertension (DASH). Total ST h/wk was dichotomized at the median and labeled "low" or "high." In weighted unadjusted and adjusted regression models, BP was assessed in relation to diet scores (linear and threshold associations) and combinations of dichotomized diet-quality scores ("poor" = lowest quartile compared with "not poor" = upper 3 quartiles) and ST.

RESULTS

Higher mean SBP and DBP occurred mainly in women with a '"poor" diet-quality score (AHEI and DASH). Among womens with a "poor"-quality diet (on the basis of the AHEI score) and "high" ST, (N = 93) adjusted mean SBP and DBP were 4.5 mmHg and 4.4 mmHg higher, respectively, than that of the counterparts who did not have a poor-quality diet and had "low" ST (N = 275). Results were similar in analyses using the DASH diet score.

CONCLUSIONS

Women with poor-quality diets and more ST may need closer BP monitoring. Even modest improvements in womens' diet quality and reductions in ST might help lower their BP, but this observation needs testing in prospective studies..

Primary prevention of cardiovascular disease in women

Ischemic heart disease is the primary cause of cardiovascular disease (CVD) mortality in both men and women. Strategies targeting traditional modifiable risk factors are essential - including hypertension, smoking, dyslipidemia and diabetes mellitus - particularly for atherosclerosis, but additionally for stroke, heart failure and some arrhythmias. However, challenges related to education, screening and equitable access to effective preventative therapies persist, and are particularly problematic for women around the globe and those from lower socioeconomic groups. The association of female-specific risk factors (e.g. premature menopause, gestational hypertension, small for gestational age births) with CVD provides a potential window for targeted prevention strategies. However, further evidence for specific effective screening and interventions is urgently required. In addition to population-level factors involved in increasing the risk of suffering a CVD event, efforts are leveraging the enormous potential of blood-based 'omics', improved imaging biomarkers and increasingly complex bioinformatic analytic approaches to strive toward more personalized early disease detection and personalized preventative therapies. These novel tactics may be particularly relevant for women in whom traditional risk factors perform poorly. Here we discuss established and emerging approaches for improving risk assessment, early disease detection and effective preventative strategies to reduce the mammoth burden of CVD in women.

Differences in the Incidence of Hypotension and Hypertension between Sexes during Non-Cardiac Surgery: A Systematic Review and Meta-Analysis

Background: Major determinants of blood pressure (BP) include sex and age. In youth, females have lower BP than males, yet in advanced age, more pronounced BP increases result in higher average BPs in females over 65. This hypothesis-generating study explored whether age-related BP divergence impacts the incidence of sex-specific intraoperative hypotension (IOH) or hypertension. Methods: We systematically searched PubMed and Embase databases for studies reporting intraoperative BP in males and females in non-cardiac surgery. We analyzed between-sex differences in the incidence of IOH and intraoperative hypertension (primary endpoint). Results: Among 793 identified studies, 14 were included in this meta-analysis, comprising 1,110,636 patients (56% female). While sex was not associated with IOH overall (females: OR 1.10, 95%CI [0.98-1.23], I2 = 99%), a subset of studies with an average age ≥65 years showed increased exposure to IOH in females (OR 1.17, 95%CI [1.01-1.35], I2 = 94%). One study reported sex-specific differences in intraoperative hypertension, with a higher incidence in females (31% vs. 28%). Conclusions: While sex-specific reporting on intraoperative BP was limited, IOH did not differ between sexes. However, an exploratory subgroup analysis offers the hypothesis that females of advanced age may face an increased risk of IOH, warranting further investigation.

A comparison of the disease occurrence of cerebrovascular diseases, diabetes mellitus, hypertensive diseases, and ischaemic heart diseases among hospitalized older adults in Thailand

This observational research analyzed public hospital data from the Thailand Ministry of Public Health website to investigate gender differences in four categories of non-communicable diseases (NCDs) affecting hospitalized senior Thai populations for 12 years. This study aimed to determine the cumulative effects and analyze the odds ratio (OR) according to ICD-10 cause categories for the data from 2010 to 2021, accounting for 1,327,093 cases in 2010 and 2,275,936 cases in 2021. The findings revealed statistically significant gender differences in four categories of NCDs. Men were found to be more likely than women to have two types of NCDs, as measured by the OR (95%CI): cerebrovascular diseases (OR 1.34-1.47, 95%CI 1.32-1.48), and ischaemic heart disease (OR 1.24-1.63, 95%CI 1.23-1.64). Conversely, diabetes mellitus (OR 0.64-0.84, 95%CI 0.63-0.85) and hypertensive disorders (OR 0.82-0.95, 95%CI 0.81-0.97) were discovered to have a lower likelihood of ratios related in men compared to women. However, the trend of all four NCDs in men has significantly increased every year: cerebrovascular diseases = 0.0093 year(s) + 1.3391, (R2 0.82, p-value 0.001); diabetes mellitus = 0.0171 year(s) + 0.6143, (R2 0.97, p-value 0.001); hypertension = 0.0125 year(s) + 0.8091, (R2 0.96, p-value 0.001); and ischaemic heart disease = 0.0345 year(s) + 1.1884, (R2 0.99, p-value 0.001).Gender, a crucial biological factor, contributes to variations in the prevalence of illness. As such, it is essential to prioritize the disease risk occurrence and preventive care for men and women separately, with a focus on implementing more detailed screening and detection strategies, as well as tailored interventions.

Sex influences blood pressure but not blood pressure variability in response to dietary sodium and potassium in salt-resistant adults

Dietary sodium and potassium have been shown to affect blood pressure (BP) but their influence on BP variability (BPV) is less studied as is the influence of sex. The aim of this study was to compare 24 h BP and short-term BPV in response to varying dietary levels of sodium and potassium in healthy non-obese normotensive salt-resistant adults. We hypothesized that high sodium would increase short-term BP and BPV while the addition of high potassium would counteract this increase. Furthermore, we hypothesized that women would experience greater increases in BPV under high sodium conditions compared to men while potassium would attenuate this response. Thirty-seven participants (17 M/20 W; 27 ± 5 years old; BMI 24.3 ± 3 kg/m2) completed seven days each of the following randomized diets: moderate potassium/low sodium (MK/LS), moderate potassium/high sodium (MK/HS) and high potassium/high sodium (HK/HS). BP and short-term BPV were assessed using 24 h ambulatory BP monitoring starting on day 6. BPV was calculated using the average real variability (ARV) index. Twenty-four hour, daytime, and nighttime systolic BP (SBP) were lower in women compared to men regardless of diet. However, 24 h and daytime SBP were lowered in women on the HK/HS diet compared to the MK/HS diet. There were no significant effects of diet or sex for 24 h, daytime or nighttime SBP ARV. However, men exhibited a higher 24 hDBP ARV than women regardless of diet. In conclusion, a high potassium diet lowered BP under high sodium conditions in women alone while men exhibited higher short-term BPV that was not influenced by diet.

The effects of aerobic exercise on cardiometabolic health in postmenopausal females: A systematic review and meta-analysis of randomized controlled trials

BACKGROUND

After menopause, reductions in ovarian hormones increase the risk of cardiovascular disease. Aerobic exercise training has been shown to reduce cardiovascular risk in older adults, but its effectiveness in postmenopausal females is less definitive.

OBJECTIVES

The objectives of this study were to examine the: (1) effects of aerobic training, and (2) association between aerobic training intensity and cardiometabolic health outcomes in postmenopausal females.

DESIGN

Systematic review and meta-analysis of randomized controlled trials.

DATA SOURCES AND METHODS

Six electronic databases were searched from inception to July 21, 2023 for aerobic training interventions reporting cardiometabolic outcomes in postmenopausal females. Data were synthesized qualitatively and random-effects meta-analyses and subgroup analyses (light, moderate, and vigorous intensity) were performed. Grading of Recommendations, Assessment, Development and Evaluation was used to assess the certainty of evidence.

RESULTS

Fifty-nine studies (n = 4,225; 45-78 years old) were identified, 53 (n = 3,821) were included in the quantitative analyses. Aerobic training interventions varied in frequency (3-21×/week), intensity, type, time (8-60 min/session), and duration (3-52 weeks). Aerobic training improved systolic blood pressure (mean difference (MD) = -4.41 mmHg, 95% confidence interval (95%CI) [-7.29, -1.52], p = 0.01), resting heart rate (MD = -3.08 bpm, 95%CI [-5.11, -1.05], p < 0.01), body mass index (BMI, MD = -0.65 kg/m2, 95%CI [-0.99, -0.31], p < 0.01), waist circumference (MD = -2.03 cm, 95%CI [-2.65, -1.41], p < 0.01), body fat (MD = -2.57 kg, 95%CI [-3.65, -1.49], p < 0.01), low-density lipoprotein cholesterol (MD = -10.46 mg/dL, 95%CI [-16.31, -4.61], p < 0.01), high-density lipoprotein cholesterol (MD = 3.28 mg/dL, 95%CI [0.20, 6.36], p = 0.04) and cardiorespiratory fitness (standardized MD = 1.38, 95%CI [1.13, 1.64], p < 0.01). There was a very low certainty of evidence for all outcomes. In subgroup analyses, light- and vigorous intensities were beneficial for BMI with no effect for moderate-intensity exercise (p < 0.01). Light intensity showed a beneficial effect (p = 0.02) for glucose levels (p < 0.01) and triglycerides; there was no effect with moderate or vigorous intensities.

CONCLUSION

Aerobic training may improve cardiometabolic health outcomes in postmenopausal females. There may be differential effects of exercise intensity on BMI, blood triglycerides, and blood glucose; however, this warrants further investigation.

The Cardiovascular Impact of Obstructive Sleep Apnea in Women: Current Knowledge and Future Perspectives

Overall, cardiovascular diseases have many sex-related differences in prevalence, clinical presentation, and outcomes. A considerable amount of evidence suggests that obstructive sleep apnea (OSA) increases the risk for several cardiovascular diseases. Only recently, the sex-related differences in cardiovascular outcomes gained interest in the literature. In this review, the authors discuss the current evidence addressing the cardiovascular impact of OSA in women. Particular attention is devoted to hypertension, target-organ damage, heart failure, atrial fibrillation, and cardiovascular events (including mortality). A research agenda is proposed to increase the understanding of the relevance of OSA in women from the Cardiology perspective.

Cardiovascular Disease and Alzheimer's Disease: The Heart-Brain Axis

Cardiovascular disease (CVD) remains one of the leading causes of morbidity and mortality in aging adults across the United States. Prior studies indicate that the presence of atherosclerosis, the pathogenic basis of CVD, is linked with dementias. Alzheimer's disease (AD) and AD-related dementias are a major public health challenge in the United States. Recent studies indicate that ≈3.7 million Americans ≥65 years of age had clinical AD in 2017, with projected increases to 9.3 million by 2060. Treatment options for AD remain limited. Development of disease-modifying therapies are challenging due, in part, to the long preclinical window of AD. The preclinical incubation period of AD starts in midlife, providing a critical window for identification and optimization of AD risk factors. Studies link AD with CVD risk factors such as hypertension, inflammation, and dyslipidemia. Both AD and CVD are progressive diseases with decades-long development periods. CVD can clinically manifest several years earlier than AD, making CVD and its risk factors a potential predictor of future AD. The current review focuses on the state of literature on molecular and metabolic pathways modulating the heart-brain axis underlying the potential association of midlife CVD risk factors and their effect on AD and related dementias. Further, we explore potential CVD/dementia preventive strategies during the window of opportunity in midlife and the future of research in the field in the multiomics and novel biomarker use era.

Hypertension in Women and Pregnancy

Hypertension has been shown to have long-term cardiovascular effects if left untreated. Hypertension also has been shown to affect women during pregnancy, which can be detrimental not only to the patient but also to the fetus. Early identification and treatment are paramount to prevent adverse outcomes. This article details the epidemiology, clinical presentation, diagnosis, and treatment of essential hypertension in women, gestational hypertension, preeclampsia, and eclampsia.

The co-occurrence and cumulative prevalence of hypertension, rheumatoid arthritis, and hypothyroidism in preterm-born women in the Women's Health Initiative

Emerging evidence suggests that preterm-born individuals (<37 weeks gestation) are at increased risk of developing chronic health conditions in adulthood. This study compared the prevalence, co-occurrence, and cumulative prevalence of three female predominant chronic health conditions - hypertension, rheumatoid arthritis [RA], and hypothyroidism - alone and concurrently. Of 82,514 U.S. women aged 50-79 years enrolled in the Women's Health Initiative, 2,303 self-reported being born preterm. Logistic regression was used to analyze the prevalence of each condition at enrollment with birth status (preterm, full term). Multinomial logistic regression models analyzed the association between birth status and each condition alone and concurrently. Outcome variables using the 3 conditions were created to give 8 categories ranging from no disease, each condition alone, two-way combinations, to having all three conditions. The models adjusted for age, race/ethnicity, and sociodemographic, lifestyle, and other health-related risk factors. Women born preterm were significantly more likely to have any one or a combination of the selected conditions. In fully adjusted models for individual conditions, the adjusted odds ratios (aORs) were 1.14 (95% CI, 1.04, 1.26) for hypertension, 1.28 (1.12, 1.47) for RA, and 1.12 (1.01, 1.24) for hypothyroidism. Hypothyroidism and RA were the strongest coexisting conditions [aOR 1.69, 95% CI (1.14, 2.51)], followed by hypertension and RA [aOR 1.48, 95% CI (1.20, 1.82)]. The aOR for all three conditions was 1.69 (1.22, 2.35). Perinatal history is pertinent across the life course. Preventive measures and early identification of risk factors and disease in preterm-born individuals are essential to mitigating adverse health outcomes in adulthood.

Vascular function in hypertension: does gender dimension matter?

Blood pressure and vascular ageing trajectories differ between men and women. These differences develop due to sex-related factors, attributable to sex chromosomes or sex hormones, and due to gender-related factors, mainly related to different sociocultural behaviors. The present review summarizes the relevant facts regarding gender-related differences in vascular function in hypertension. Among sex-related factors, endogenous 17ß-estradiol plays a key role in protecting pre-menopausal women from vascular ageing. However, as vascular ageing (preceding and inducing hypertension) has a steeper increase in women than in men starting already from the third decade, it is likely that gender-related factors play a prominent role, especially in the young. Among gender-related factors, psychological stress (including that one related to gender-based violence and discrimination), depression, some psychological traits, but also low socioeconomic status, are more common in women than men, and their impact on vascular ageing is likely to be greater in women. Men, on the contrary, are more exposed to the vascular adverse consequences of alcohol consumption, as well as of social deprivation, while "toxic masculinity" traits may result in lower adherence to lifestyle and preventive strategies. Unhealthy diet habits are more prevalent in men and smoking is equally prevalent in the two sexes, but have a disproportional negative effect on women's vascular health. In conclusion, given the major and complex role of gender-related factors in driving vascular alterations and blood pressure patterns, gender dimension should be systematically integrated into future research on vascular function and hypertension and to tailor cardiovascular prevention strategies.

Association of blood pressure variability with Endothelin-1 by menopause status among Black women: findings from the Jackson Heart Study

TO THE EDITOR

Postmenopausal women have a higher risk of hypertension compared with premenopausal women possibly related to increased endothelial dysfunction in the setting of lower levels of circulating estrogen. Using data from 660 women in the Jackson Heart Study (JHS), postmenopausal women had higher daytime, nighttime and 24 h systolic blood pressure variability (BPV) compared with premenopausal women, and higher nighttime systolic BPV was associated with higher endothlin-1 (a marker of endothelial dysfunction) in postmenopausal women (ß = 0.27 [0.05, 0.50], p = 0.019), even after adjustment for possible confounders including age. These findings highlight the relevance of menopause status to blood pressure variability and the potential role of blood pressure variability in the development of high endothelin-1 in postmenopausal women.

Sexual Dimorphic Interplays Between Gut Microbiota and Antihypertensive Drugs

PURPOSE OF THE REVIEW

The purpose of this study is to review the current literature regarding gut microbiota in blood pressure regulation and its interactions with antihypertensive drugs and to discuss how sex differences in gut microbiota contribute to sexual dimorphism of hypertension and treatment.

RECENT FINDINGS

The significance of gut microbiota in blood pressure regulation and hypertension etiology is growingly recognized. Targeting the dysbiotic microbiota is proposed to be a new therapeutic method. Recently, a few studies demonstrated that the gut microbiota is highly involved in the modulation of the efficacy of antihypertensive drugs, suggesting a novel mechanism by which gut microbiota plays a role in treatment-resistant hypertension. Furthermore, studies on sex differences in gut microbiota, etiology of hypertension, and sex bias in prescription of antihypertensive medications have revealed promising avenues in sexual dimorphism-based precision medicine. However, no scientific questions are ever raised on how sex differences in gut microbiota contribute to the sex specific responses of certain classes of antihypertensive drugs. Given the dynamics and complexity among individuals, precision medicine is proposed of great potential. We review current knowledge on the interactions between gut microbiota, hypertension, and antihypertensive drugs with an emphasis on sex as a crucial determinant. We propose that sex differences in gut microbiota be a research focus to advance our understanding of hypertension management.

Longitudinal profiles of neighborhood socioeconomic vulnerability influence blood pressure changes across the female midlife period

PURPOSE

To examine whether longitudinal exposure to neighborhood socioeconomic vulnerability influences blood pressure changes throughout midlife in a racially, ethnically, and geographically-diverse cohort of women transitioning through menopause.

METHODS

We used longitudinal data on 2738 women (age 42-52 at baseline) living in six United States cities from The Study of Women's Health Across the Nation. Residential histories, systolic blood pressures (SBP), and diastolic blood pressures (DBP) were collected annually for ten years. We used longitudinal latent profile analysis to identify patterns of neighborhood socioeconomic vulnerability occurring from 1996 to 2007 in participant neighborhoods. We used linear mixed-effect models to determine if a woman's neighborhood profile throughout midlife was associated with blood pressure changes.

RESULTS

We identified four unique profiles of neighborhood socioeconomic vulnerability - differentiated by residential socioeconomic status, population density, and vacant housing conditions - which remained stable across time. Women residing in the most socioeconomically vulnerable neighborhoods experienced the steepest increase in annual SBP growth by 0.93 mmHg/year (95% CI: 0.65-1.21) across ten-year follow-up.

CONCLUSIONS

Neighborhood socioeconomic vulnerability was significantly associated with accelerated SBP increases throughout midlife among women.

Risk factors associated with attendance at postpartum blood pressure follow-up visit in discharged patients with hypertensive disorders of pregnancy

BACKGROUND

This study aims to investigate the risk factors for not returning to postpartum blood pressure (BP) follow-up visit at different time points in postpartum discharged hypertensive disorders of pregnancy (HDP) patients. Likewise, females with HDP in China should have a BP evaluation continuously for at least 42 days postpartum and have BP, urine routine, and lipid and glucose screening for 3 months postpartum.

METHODS

This study is a prospective cohort study of postpartum discharged HDP patients. Telephone follow-up was conducted at 6 weeks and 12 weeks postpartum, the maternal demographic characteristics, details of labor and delivery, laboratory test results of patients at admission, and adherence to BP follow-up visits postpartum were collected. While logistic regression analysis was used to analyze the factors associated with not returning to postpartum BP follow-up visit at 6 weeks and 12 weeks after delivery, the receiver operating characteristic (ROC) curve was drawn to evaluate the model's predictive value for predicting not returning to postpartum BP visit at each follow-up time point.

RESULTS

In this study, 272 females met the inclusion criteria. 66 (24.26%) and 137 (50.37%) patients did not return for postpartum BP visit at 6 and 12 weeks after delivery. A multivariate logistic regression analysis identified education level of high school or below (OR = 3.71; 95% CI = 2.01-6.85; p = 0.000), maximum diastolic BP during pregnancy (OR = 0.97; 95% CI = 0.94-0.99; p = 0.0230)and delivery gestational age (OR = 1.12; 95% CI = 1.005-1.244; p = 0.040)as independent risk factors in predicting not returning to postpartum BP follow-up visit at 6 weeks postpartum, and education level of high school or below (OR = 3.20; 95% CI = 1.805-5.67; p = 0.000), maximum diastolic BP during pregnancy (OR = 0.95; 95% CI = 0.92-0.97; p = 0.000), delivery gestational age (OR = 1.13; 95% CI = 1.04-1.24; p = 0.006) and parity (OR = 1.63; 95% CI = 1.06-2.51; p = 0.026) as risk factors for not returning to postpartum BP follow-up visit at 12 weeks postpartum. The ROC curve analysis indicated that the logistic regression models had a significant predictive value for identify not returning to BP follow-up visit at 6 and 12 weeks postpartum with the area under the curve (AUC) 0.746 and 0.761, respectively.

CONCLUSION

Attendance at postpartum BP follow-up visit declined with time for postpartum HDP patients after discharge. Education at or below high school, maximum diastolic BP during pregnancy and gestational age at delivery were the common risk factors for not returning for BP follow-up visit at 6 and 12 weeks postpartum in postpartum HDP patients.

Association between atherogenic index of plasma and prehypertension or hypertension among normoglycemia subjects in a Japan population: a cross-sectional study

OBJECTIVE

The atherogenic index of plasma (AIP), consisting of triglycerides and high-density lipoprotein cholesterol, is applied to estimate the cardiovascular disease risk. The evidence regarding the association between AIP and prehypertension or hypertension remains inconclusive. This study was conducted to investigate the association of AIP and prehypertension or hypertension in normoglycemic subjects in Japan.

METHODS

In the present cross-sectional study, 15,453 normoglycemic participants aged 18 years or older in Gifu, Japan, were evaluated. The selected participants were separated into four groups in the light of AIP quartiles, ranging from the lowest quartile (Q1) to the highest quartile (Q4). And the association between AIP and prehypertension or hypertension was explored with multivariate logistic regression by gradually adjusting model.

RESULTS

Among the 15,453 participants, aged of 43.7 ± 8.9 years, and of whom 45.5% were females, the prevalence rates of prehypertension or hypertension were 27.68% (4,278) and 6.23% (962) respectively. In multivariate logistic regression analyses, participants in the highest AIP quartile had an increase risk in prehypertension and hypertension, compared with participants the lowest one, the odds ratios (OR) were 1.15 (95%CI: 1.00-1.13, P = 0.045) for prehypertension and 1.54 (95%CI:1.16-2.04, P = 0.003) for hypertension after adjusting confounders. In subgroup analyses, the high risk of hypertension was also observed for female participants in the highest AIP quartile (Q4) (OR = 2.19, 95%CI: 1.37-3.49, P = 0.001), especially between the ages of 40 and 60 years (OR = 2.20, 95%CI: 1.24-3.88, P = 0.007).

CONCLUSIONS

Higher AIP is significantly and positively associated with the risk of prehypertension or hypertension in normoglycemic subjects in Gifu, Japan, which was more pronounced in the female population, especially between the years of 40 and 60.

Individual-related factors associated with treatment adherence among hypertensive patients

Background

Currently, some of the most prevalent illnesses are attributable to external sources, such as chronic disorders that threaten people's health. The goal of the study was to investigate the differences in individual characteristics associated with treatment adherence among hypertension patients.

Materials and Methods

In this descriptive cross-sectional study, 176 hypertensive patients who reviewed primary healthcare facilities in Babylon Province were included. Experts were used to ensure the study questionnaire's validity, and a pilot study was used to ensure its reliability. Using a standardized questionnaire and interviewing methods, data were collected and analyzed.

Results

According to the study's findings, participants' average ages were 59 (10.86), 67% of them were over 60, 55.1% and 65.3% of them were men and married respectively, nearly half of them had moderate monthly income, the unemployed percentage was 61.9%, and 36.4% had completed their secondary education. Two-thirds, or 70.5%, of hypertension patients, reported poor treatment adherence. Ages 30-59, male patients, married, highincome, and college-educated patients showed significantly better treatment compliance (P<0.05).

Conclusions

Every individual characteristic of patients with high blood pressure is regarded as a predictor of therapy adherence. The current study is one of the few in Iraq to evaluate treatment adherence and look into the various elements that may influence it using the survey approach. Future research on the subject of antihypertensive treatment adherence in the hypertensive population in Iraq employing a representative sample, a qualitative methodology, and more factor exploration may offer additional insights.
