Menopause in the workplace: Challenges, impact, and next steps. Maturitas 2024; 185:107983. [PMID: 38581822 DOI: 10.1016/j.maturitas.2024.107983] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2023] [Revised: 02/23/2024] [Accepted: 03/27/2024] [Indexed: 04/08/2024]
Abstract
INTRODUCTION Menopause is a natural part of a woman's life that coincides with a time when many women play significant roles in the workforce. Menopause symptoms, such as hot flashes, fatigue, and difficulty with concentration and memory, can have a negative effect on work productivity and efficiency. OBJECTIVES This paper summarizes the impact of menopause in the workplace, with an emphasis on the impact of symptoms on employed women and how the workplace influences their experiences. It highlights economic implications, promotes awareness, and suggests potential next steps. METHODS A search for papers was conducted between August and November 2023 in the PubMed and Medline databases. Papers were selected based on personal experience and interpretation of the findings. Recommendations for managing menopause symptoms in the workplace and guidance on an optimal workplace intervention strategy were provided. RESULTS Women experiencing severe menopause symptoms are more likely to report adverse work outcomes, including absenteeism and job-related decisions such as quitting, retiring early, or declining promotions than women experiencing few symptoms. Factors such as a lack of awareness about menopause, inflexible work conditions, and high-stress jobs can exacerbate the severity of these symptoms. Additionally, unaddressed menopause symptoms contribute to both direct and indirect economic costs, including medical resource utilization and lost work productivity, resulting in a substantial economic burden. CONCLUSION Menopause symptoms impair women's work experiences and productivity. In addition to dismantling the stigma associated with menopause, it is critical to create and implement menopause workplace policies and interventions aimed at supporting women in this universal life stage.

Weight loss response to semaglutide in postmenopausal women with and without hormone therapy use. Menopause 2024; 31:266-274. [PMID: 38446869 DOI: 10.1097/gme.0000000000002310] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 03/08/2024]
Abstract
OBJECTIVE To compare weight loss response and changes in cardiometabolic risk markers in postmenopausal women using semaglutide with and without menopause hormone therapy (HT) use. METHODS Retrospective cohort study of postmenopausal women treated with semaglutide for overweight or obesity for ≥3 months. Endpoints: total body weight loss percentage (TBWL%) at 3, 6, 9, and 12 months after semaglutide initiation; and percentage of women achieving ≥5% and ≥10% TBWL and changes in cardiometabolic risk markers (glucose, blood pressure, and lipids) at 12 months. RESULTS There were 16 women on HT and 90 on no-HT; mean age 56 ± 8 vs 59 ± 8 yr, P = 0.2 and mean BMI 36 ± 5 vs 39 ± 8 kg/m 2 , P = 0.1; respectively. Among women on no-HT, White race, dyslipidemia, and depression were more prevalent. Women on HT had a higher TBWL% at 3, 6, 9, and 12 months: 7 ± 3% vs 5 ± 4%, P = 0.01; 13 ± 6% vs 9 ± 5%, P = 0.01; 15 ± 6% vs 10 ± 6%, P = 0.02; and 16 ± 6% vs 12 ± 8%, P = 0.04; respectively. After adjusting for potential confounders, this association remained significant across time. At 12 months, a greater percentage of women on HT achieved ≥5% and ≥10% TBWL. Both groups experienced an improvement in cardiometabolic risk markers. CONCLUSION In postmenopausal women with overweight or obesity treated with semaglutide, HT use was associated with an improved weight loss response. This association was maintained when adjusted for confounders. Larger studies should be conducted to confirm these results.

Menopause transition and cardiovascular disease risk. Maturitas 2024; 185:107974. [PMID: 38555760 DOI: 10.1016/j.maturitas.2024.107974] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Revised: 03/12/2024] [Accepted: 03/14/2024] [Indexed: 04/02/2024]
Abstract
The risk of cardiovascular disease (CVD) notably increases in the fifth decade of a woman's life, coinciding with the onset of menopause and occurring 10 years later than the similar age-related increase in men. Menopause marks a significant transition in a woman's life and is accompanied by cardiometabolic changes, including a shift in body composition, increased blood pressure, disruptions in lipoproteins, and insulin resistance. There is increasing evidence that the menopause transition is a risk factor for CVD, independent of age-related changes, especially considering that the earlier the onset of menopause, the greater is the CVD risk. Further, menopause-related symptoms such as vasomotor symptoms, sleep disturbances, and mood changes may all have a direct impact on CVD risk. In this review, we summarize the current literature regarding CVD in midlife women, focusing on the cardiometabolic changes related to ovarian aging versus chronological aging, as well as those related to specific menopause characteristics, including age, type of menopause and the use of menopause hormone therapy.

Abstract
BACKGROUND Proprotein convertase subtisilin/kexin 9 (PCSK9) raises low-density lipoprotein cholesterol (LDL-C) levels and is associated with inflammation, which is elevated in HIV and hepatitis C virus (HCV) infection. We compared PCSK9 levels in people with co-occurring HIV and HCV (HIV/HCV) vs. HIV alone, and evaluated the impact of HCV direct-acting antiviral (DAA) therapy on PCSK9. DESIGN A prospective, observational cohort study. METHODS Thirty-five adults with HIV/HCV and 37 with HIV alone were evaluated, all with HIV virologic suppression and without documented cardiovascular disease. Circulating PCSK9 and inflammatory biomarkers were measured at baseline and following HCV treatment or at week 52 (for HIV alone) and compared using Wilcoxon tests and Spearman correlations. RESULTS At baseline, PCSK9 trended higher in HIV/HCV vs. HIV alone (307 vs. 284 ng/ml, P = 0.06). Twenty-nine participants with HIV/HCV completed DAA therapy with sustained virologic response. PCSK9 declined from baseline to posttreatment 1 (median 7.3 weeks after end of therapy [EOT]) and posttreatment 2 (median 43.5 weeks after EOT), reaching levels similar to HIV alone; median within-person reduction was -60.5 ng/ml ( P = 0.003) and -55.6 ng/ml ( P = 0.02), respectively. Decline in PCSK9 correlated with decline in soluble (s)E-selectin and sCD163 ( r = 0.64, P = 0.002; r = 0.58, P = 0.008, respectively), but not with changes in LDL-C or other biomarkers. No significant change in PCSK9 occurred in the HIV alone group over 52 weeks. CONCLUSION PCSK9 declined with DAA therapy in participants with HIV/HCV, correlating with declines in several inflammatory biomarkers but not LDL-C. Elevated PCSK9 with HCV may be linked to particular HCV-associated inflammatory pathways more so than cholesterol homeostasis.

Weight Gain in Midlife Women. Curr Obes Rep 2024:10.1007/s13679-024-00555-2. [PMID: 38416337 DOI: 10.1007/s13679-024-00555-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 02/11/2024] [Indexed: 02/29/2024]
Abstract
PURPOSE OF REVIEW To summarize the evidence and clinical implications of weight and body composition changes during midlife in women and provide an overview of weight gain prevention and management in this population. RECENT FINDINGS Aging-related changes such as decreased energy expenditure and physical activity are important culprits for weight gain in midlife women. The hormonal changes of menopause also influence body adiposity distribution and increase central adiposity. These body changes can have health consequences including the development of cardiometabolic diseases, osteoarthritis, cancer, worsening in cognition, mental health, and menopause symptoms. Midlife women experience changes related to aging, menopause, and lifestyle which favor weight gain. Clinical practice should focus on early counseling and anticipatory guidance on the importance of dietary changes and physical activity to attenuate this phenomenon. Future research should focus on the longitudinal relationship between weight trends in midlife and health consequences and mortality.

Abstract
BACKGROUND Breast cancer (BC) is the most common cancer in women. While the combination of improved screening, earlier detection, and advances in therapeutics has resulted in lower BC mortality, BC survivors are now increasingly dying of cardiovascular disease. Cardiovascular disease in the leading cause of non-cancer related mortality among BC survivors. This situation underscores the critical need to research the role of modifiable cardiometabolic risk factors, such as excess adiposity, that will affect BC remission, long-term survivorship, and overall health and quality of life. PURPOSE First, this review summarizes the evidence on the connection between adipose tissue and BC. Then we review the data on weight trends after BC diagnosis with a focus on the effect of weight gain on BC recurrence and BC- and non-BC-related death. Finally, we provide a guide for weight management in BC survivors, considering the available data on the effect of weight loss interventions on BC.

Abstract
CONTEXT Endothelial dysfunction is a preclinical cardiovascular disease (CVD) marker. Due to various neuroendocrine aberrations, functional hypothalamic amenorrhea (FHA) may be a sex-specific risk factor for CVD in young women. OBJECTIVE To investigate endothelial function in women with FHA, compared with eumenorrheic controls and recently menopausal women. METHODS We performed a cross-sectional analysis among women with FHA (n = 30), eumenorrheic controls (n = 29), and recently menopausal women (n = 30). FHA was defined as amenorrhea ≥3 consecutive months, estradiol <50 pg/mL, follicle-stimulating hormone (FSH) < 10 mIU/mL, and luteinizing hormone (LH) < 10 mIU/mL, excluding other etiologies. Participants were recruited through obstetrics and gynecology referrals, social media advertising, and review of electronic health records. Preclinical CVD was measured using EndoPAT 2000 to calculate reactive hyperemic index (RHI). RHI ≤1.67 indicates endothelial dysfunction. RESULTS Mean estradiol levels in women with FHA, as compared with eumenorrheic controls and recently menopausal women, were 29.0 ± 18.1, 46.4 ± 15.7, and 10.9 ± 14.4 pg/mL (P < .0001), respectively. Women with FHA had lower insulin (P = .0095) and higher cortisol (P = .0004) compared with controls. RHI was significantly lower in women with FHA compared with eumenorrheic controls and recently menopausal women (1.8 ± 0.5 vs 2.2 ± 0.5 vs 2.2 ± 0.6, respectively; P = .008), and 35% of women with FHA had RHI ≤1.67, consistent with endothelial dysfunction. CONCLUSION These results demonstrate endothelial dysfunction in 1 out of 3 young women with FHA. FHA may be a contributor to preclinical CVD, and it is not explained by hypoestrogenemia alone.

Abstract
OBJECTIVE Adverse childhood experiences (ACEs) are reported in more than half of the women in the United States and have been shown to negatively impact the menopause experience. The objective of this study was to evaluate the association between ACEs and age at natural menopause. METHODS This is a cross-sectional study conducted among participants of the Data Registry on the Experiences of Aging, Menopause, and Sexuality (DREAMS). The registry included women who were seen for consultations in the women's health clinic at Mayo Clinic, Rochester, between May 2015 and December 2016. Only postmenopausal women were included in this analysis. Childhood adversity was assessed with the validated ACE questionnaire. Age at natural menopause was self-reported. The association between ACEs and age at menopause was evaluated using a multivariable linear regression model adjusting for multiple confounders. RESULTS A total of 350 women were evaluated. The mean age was 59.2 years, and a majority were White (92.9%), married/partnered (82%), and educated (91.2% with at least some college education). Women with a history of at least four ACEs were estimated to reach natural menopause 1.3 years sooner than women with no ACE in multivariable analysis, but the results were not statistically significant (95% confidence interval, -3.2 to 0.6; P = 0.18). CONCLUSIONS Although stressful life experiences such as ACEs may negatively influence health for midlife women, this study did not find an association with the age at natural menopause.

History of infertility and sexual dysfunction in midlife women: Is there a link? J Sex Med 2023; 20:1188-1194. [PMID: 37537692 PMCID: PMC10472170 DOI: 10.1093/jsxmed/qdad097] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2023] [Revised: 05/16/2023] [Accepted: 06/26/2023] [Indexed: 08/05/2023]
Abstract
BACKGROUND Infertility has been linked with an increased risk of sexual dysfunction in reproductive-aged women, with longer periods of infertility associated with a greater risk. AIM The study's aim was to examine whether a history of infertility treatment in women is linked to sexual dysfunction during midlife. METHODS The cross-sectional study was conducted among sexually active women, between the ages of 45 and 65 years, who sought consultation at the women's health clinics at a US tertiary care center. History of infertility treatment was assessed with a single question that asked participants if they were treated for infertility in the past. The association between a history of infertility treatment and sexual dysfunction-which was diagnosed by a combination of Female Sexual Function Index score ≤26.55 and Female Sexual Distress Scale-Revised score ≥11-was assessed in a multivariable logistic regression model that adjusted for multiple confounders. OUTCOMES The primary outcome was sexual dysfunction in midlife women. RESULTS The analysis included 5912 women, with a mean age of 54.1 years. Nearly 16% of women reported receiving treatment for infertility. More than half the women (55%) had sexual dysfunction: 56.3% of those with previous fertility treatments and 54.4% of those without any fertility treatment (P = .3). Receiving treatment for infertility in the younger years did not significantly increase the odds of sexual dysfunction in midlife in univariate (odds ratio, 1.08; 95% CI, 0.94-1.24; P = .3) and multivariable analyses (odds ratio, 1.11; 95% CI, 0.96-1.29; P = .17). CLINICAL IMPLICATIONS While infertility is known to be predictive of sexual dysfunction in women during their reproductive years, there was no association between a history of infertility treatment and sexual dysfunction in midlife women in the current study. STRENGTHS AND LIMITATIONS The study used validated questionnaires accounting for sexual complaints and distress and adjusted for multiple confounding factors. Limitations include the selection bias introduced by the study of women presenting for evaluation of sexual dysfunction, which may have been a result of factors stronger than the influence of infertility. Other limitations include the study's cross-sectional nature with suboptimal racial and ethnic representation. CONCLUSION Although infertility is commonly associated with female sexual dysfunction in women of reproductive age, the association was not present in midlife women in the current study.

Abstract
BACKGROUND Premature menopause is a risk factor for accelerated cardiovascular aging, but underlying mechanisms remain incompletely understood. This study investigated the role of leukocyte telomere length (LTL), a marker of cellular aging and genomic instability, in the association of premature menopause with cardiovascular disease. METHODS Participants from the UK Biobank and Women's Health Initiative with complete reproductive history and LTL measurements were included. Primary analyses tested the association between age at menopause and LTL using multivariable-adjusted linear regression. Secondary analyses stratified women by history of gynecologic surgery. Mendelian randomization was used to infer causal relationships between LTL and age at natural menopause. Multivariable-adjusted Cox regression and mediation analyses tested the joint associations of premature menopause and LTL with incident coronary artery disease. RESULTS This study included 130 254 postmenopausal women (UK Biobank: n=122 224; Women's Health Initiative: n=8030), of whom 4809 (3.7%) had experienced menopause before age 40. Earlier menopause was associated with shorter LTL (meta-analyzed ß=-0.02 SD/5 years of earlier menopause [95% CI, -0.02 to -0.01]; P=7.2×10-12). This association was stronger and significant in both cohorts for women with natural/spontaneous menopause (meta-analyzed ß=-0.04 SD/5 years of earlier menopause [95% CI, -0.04 to -0.03]; P<2.2×10-16) and was independent of hormone therapy use. Mendelian randomization supported a causal association of shorter genetically predicted LTL with earlier age at natural menopause. LTL and age at menopause were independently associated with incident coronary artery disease, and mediation analyses indicated small but significant mediation effects of LTL in the association of menopausal age with coronary artery disease. CONCLUSIONS Earlier age at menopause is associated with shorter LTL, especially among women with natural menopause. Accelerated telomere shortening may contribute to the heightened cardiovascular risk associated with premature menopause.

Abstract
Women with signs and symptoms of ischemia and no obstructive coronary artery disease (INOCA) often have coronary microvascular dysfunction (CMD). It can be diagnosed by coronary function testing (CFT), which is an invasive coronary angiogram procedure. Frequently, these women have persistent angina despite medical therapy, but it is not clear whether it is due to worsening or persistent CMD or inadequate therapy. In this brief report, we describe findings of repeat CFT in a case series of 12 women undergoing repeat CFT for the assessment of persistent angina in order to better understand the evolving pathology.

Abstract
INTRODUCTION Infertility affects 15% of women of reproductive age in the United States. The use of assisted reproductive technology (ART) has been rising globally, as well as a growing recognition of reproductive factors that increase risk for cardiovascular disease (CVD). AREAS COVERED Women with infertility who use ART are more likely to have established CVD risk factors, such as obesity, dyslipidemia, hypertension, and diabetes. They are also more likely to experience adverse pregnancy outcomes, which are associated with both peripartum and long-term cardiovascular complications. ART may lead to increased cardiometabolic demands due to ovarian stimulation, pregnancy itself, and higher rates of multifetal gestation. Preeclampsia risk appears greater with frozen rather than fresh embryo transfers. EXPERT OPINION The use of ART and its association with long term CVD has not been well-studied. Future prospective and mechanistic studies investigating the association of ART and CVD risk may help determine causality. Nevertheless, CVD risk screening is critical pre-pregnancy and during pregnancy to reduce pregnancy complications that elevate future CVD risk. This also offers a window of opportunity to connect patients to longitudinal care for early management of cardiometabolic risk profile and initiation of preventive lifestyle and pharmacotherapy interventions tailored toward patient-specific risk factors.

Abstract
Background While autoimmune rheumatic diseases (ARDs) have been linked with coronary microvascular dysfunction (CMD), the relationship between ARD and CMD in women with signs and symptoms of ischemia and no obstructive arteries (INOCA) are not well described. We hypothesized that among women with CMD, those with ARD history have greater angina, functional limitations, and myocardial perfusion compromise compared to those without ARD history. Methods Women with INOCA and confirmed CMD by invasive coronary function testing were included from the Women's Ischemia Syndrome Evaluation-Coronary Vascular Dysfunction (WISE-CVD) project (NCT00832702). Seattle Angina Questionnaire (SAQ), Duke Activity Status Index (DASI), and cardiac magnetic resonance myocardial perfusion reserve index (MPRI) were collected at baseline. Chart review was performed to confirm self-reported ARD diagnosis. Results Of the 207 women with CMD, 19 (9%) had a confirmed history of ARD. Compared to those without ARD, women with ARD were younger (p = 0.04). In addition, they had lower DASI-estimated metabolic equivalents (p = 0.03) and lower MPRI (p = 0.008) but similar SAQ scores. There was a trend towards increased nocturnal angina and stress-induced angina in those with ARD (p = 0.05 for both). Invasive coronary function variables were not significantly different between groups. Conclusions Among women with CMD, women with a history of ARD had lower functional status and worse myocardial perfusion reserve compared to women without ARD. Angina-related health status and invasive coronary function were not significantly different between groups. Further studies are warranted to understand mechanisms contributing to CMD among women with ARDs with INOCA.

Abstract
OBJECTIVE To further examine a potential link between migraine and vasomotor symptoms as well as hypertension as a cardiovascular disease risk factor, potentially explaining the association in midlife women. PATIENTS AND METHODS We conducted a cross-sectional analysis from the Data Registry on Experiences of Aging, Menopause, and Sexuality using questionnaire data from women aged 45 to 60 years seen in women's clinics at a tertiary care center from May 15, 2015, through January 31, 2022. A history of migraine was self-reported; menopause symptoms were assessed with the Menopause Rating Scale. Associations between migraine and vasomotor symptoms were evaluated utilizing multivariable logistic regression models adjusting for multiple factors. RESULTS Of 5708 women included in the analysis, 1354 (23.7%) reported a migraine history. The total cohort had a mean age of 52.8 years, most (5184 [90.8%]) were White, and 3348 (58.7%) were postmenopausal. In adjusted analysis, women with migraine were significantly more likely to have severe/very severe hot flashes vs no hot flashes compared with women without migraine (odds ratio, 1.34; 95% CI, 1.08 to 1.66; P=.007). Migraine was associated with a diagnosis of hypertension in adjusted analysis (odds ratio, 1.31; 95% CI, 1.11 to 1.55; P=.002). CONCLUSION This large cross-sectional study confirms an association between migraine and vasomotor symptoms. Migraine also was associated with hypertension, potentially providing a link with cardiovascular disease risk. Given the high prevalence of migraine in women, this association may help identify those at risk for more severe menopause symptoms.

Abstract
OBJECTIVE To evaluate the impact of menopause symptoms on work outcomes and to assess the estimated economic impact. PATIENTS AND METHODS Women aged 45 to 60 years receiving primary care at 1 of the 4 Mayo Clinic sites were invited to participate in a survey study (Hormones and ExpeRiences of Aging) from March 1 through June 30, 2021. A total of 32,469 surveys were sent, with 5219 responses (16.1% response rate). Of the 5219 respondents, 4440 (85.1%) reported current employment information and were included in the study. The primary outcome was self-reported adverse work outcomes related to menopause symptoms assessed by the Menopause Rating Scale (MRS). RESULTS The mean age of the 4440 participants was 53.9±4.5 years, with the majority being White (4127 [93.0%]), married (3398 [76.5%]), and educated (2632 [59.3%] college graduate or higher); the mean total MRS score was 12.1, signifying moderate menopause symptom burden. Overall, 597 women (13.4%) reported at least one adverse work outcome due to menopause symptoms; 480 women (10.8%) reported missing work in the preceding 12 months (median, 3 days missed). The odds of reporting an adverse work outcome increased with increasing menopause symptom severity; women in the highest quartile of total MRS scores were 15.6 (95% CI, 10.7 to 22.7; P<.001) times more likely to have an adverse work outcome vs those in the first quartile. Based on workdays missed due to menopause symptoms, we estimate an annual loss of $1.8 billion in the United States. CONCLUSION This large cross-sectional study identified a major negative impact of menopause symptoms on work outcomes and the need to improve medical treatment for these women and make the workplace environment more supportive. Additional studies are needed to confirm these findings in larger and more diverse groups of women.

Abstract
Introduction:
Hypothalamic amenorrhea (HA) is a neuroendocrine disorder characterized by ovulatory dysfunction, anovulation, and infertility, which can be prolonged for months to years. Menstrual cycle irregularity and amenorrhea identify individuals with higher CVD risk, but existing evidence has not examined HA separately from polycystic ovary syndrome (PCOS). It remains unknown whether HA is associated with CVD events across the lifecourse.
Hypothesis:
We hypothesized that the HA phenotype (oligo/amenorrhea without PCOS traits) would identify individuals at increased risk for CVD.
Methods:
Nurses’ Health Study II participants with available information on menstrual cycle characteristics who were premenopausal and free of CVD at baseline comprised the analytic sample (n=83,281). Menstrual cycle regularity was retrospectively reported for ages 18-22y on the baseline questionnaire in 1989 while the 1993 biennial questionnaire captured current menstrual cycle regularity (at ages 29-49y); PCOS traits (severe acne, hirsutism) were additionally ascertained in 1993. Participants were followed for confirmed incident CVD (MI, stroke, and fatal CHD) from 1993 through 2017. Cox proportional hazards models estimated hazard ratios (HR) and 95% confidence intervals (CI) for the relationship between HA and CVD, adjusted for age, race/ethnicity, parental education, parental history of CVD <60y, and behavioral risk factors (smoking, physical activity, diet, alcohol intake, body mass index).
Results:
Thirteen percent of participants (n=11,071) ever had HA: 8.5% of participants (n=7,081) had HA at ages 18-22y while 6.5% (n=5,428) had HA at ages 29-46y. Persistent HA (HA at both 18-22y and 29-46 y) was identified in 1.7% of participants (n=1,438). CVD events occurred in 253 individuals who ever had HA (HA at either 18-22y or 29-46y) and 1,228 individuals without the HA phenotype. Individuals who ever had HA had a 20% higher rate of CVD (CI: 1.05-1.38). HA phenotype at ages 18-22y was not associated with CVD risk (HR=1.14; CI: 0.96-1.35) while HA phenotype at ages 29-46y was associated with a 30% higher rate of CVD (CI: 1.10-1.54) compared to individuals without HA phenotype. Individuals with persistent HA across both age ranges had a 69% higher rate of CVD (CI: 1.24-2.28). Underlying associations were strongest between ever HA and stroke (HR=1.25; CI: 1.03-1.51) and between persistent HA and CHD (HR=1.90; CI: 1.27-2.86), although case counts were small.
Conclusions:
HA phenotype in mid-adulthood identified individuals at increased risk of CVD compared to those without HA. As there are multiple HA subtypes, defined by varying combinations of psychosocial stress, anxiety, physical activity and weight loss, future studies should examine which HA subtypes are associated with CVD risk.

Abstract
Menopausal hormone therapy (HT) was widely used in the past, but with the publication of seminal primary and secondary prevention trials that reported an excess cardiovascular risk with combined estrogen-progestin, HT use declined significantly. However, over the past 20 years, much has been learned about the relationship between the timing of HT use with respect to age and time since menopause, HT route of administration, and cardiovascular disease risk. Four leading medical societies recommend HT for the treatment of menopausal women with bothersome menopausal symptoms. In this context, this review, led by the American College of Cardiology Cardiolovascular Disease in Women Committee, along with leading gynecologists, women's health internists, and endocrinologists, aims to provide guidance on HT use, including the selection of patients and HT formulation with a focus on caring for symptomatic women with cardiovascular disease risk.

Cardiovascular Complications During Delivery Admissions Associated With Assisted Reproductive Technology (from a National Inpatient Sample Analysis 2008 to 2019). Am J Cardiol 2023; 186:126-134. [PMID: 36283885 DOI: 10.1016/j.amjcard.2022.08.037] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Revised: 08/16/2022] [Accepted: 08/29/2022] [Indexed: 11/01/2022]
Abstract
Women who conceive through assisted reproductive technology (ART) have a known increased risk of obstetric complications. However, whether ART is also associated with higher risk of developing cardiovascular complications during delivery admissions has not been well established. We used data from the National Inpatient Sample (2008 to 2019) and used the International Classification of Diseases codes to identify delivery hospitalizations and ART procedures. A total of 45,867,086 weighted delivery cases were identified, of which 0.24% were among women who conceived through ART (n = 108,542). Women with an ART history were older at the time of delivery (median 35 vs 28 years, p <0.01) and had a higher prevalence of hypertension, gestational diabetes, and dyslipidemia (all, p <0.01). After adjustment for age, race/ethnicity, co-morbidities, multiple gestation, insurance, and income, ART remained an independent predictor of peripartum cardiovascular complications, including pre-eclampsia/eclampsia (adjusted odds ratio [aOR] 1.48, 95% confidence interval [CI] 1.45 to 1.51), heart failure (aOR 1.94, 95% CI 1.10 to 3.40), and cardiac arrhythmias (aOR 1.39, 95% CI 1.30 to 1.48), compared with natural conception. Likewise, the risk of acute kidney injury (aOR 2.57, 95% CI 2.25 to 2.92), ischemic stroke (aOR 1.73, 95% CI 1.24 to 2.43), hemorrhagic stroke (aOR 1.63, 95% CI 1.27 to 2.11), pulmonary edema (aOR 2.29, 95% CI 2.02 to 2.61), and venous thromboembolism (aOR 1.92, 95% CI 1.63 to 2.25) were higher with ART. However, odds of developing peripartum cardiomyopathy or acute coronary syndrome were not associated with ART. Length of stay (3 vs 2 days, p <0.01) and cost of hospitalization ($5,903 vs $3,922, p <0.01) were higher for deliveries among women with a history of ART. In conclusion, women who conceived with ART had higher risk of pre-eclampsia, heart failure, arrhythmias, stroke, and other complications during their delivery hospitalizations. This may, in part, contribute to their increased resource utilization seen.

Dyslipidemia in midlife women: Approach and considerations during the menopausal transition. Maturitas 2022; 166:14-20. [PMID: 36027726 DOI: 10.1016/j.maturitas.2022.08.001] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2022] [Revised: 07/25/2022] [Accepted: 08/04/2022] [Indexed: 11/16/2022]
Abstract
Dyslipidemia is an established risk factor for cardiovascular disease (CVD), which remains the leading cause of morbidity and mortality in women globally. The incidence of dyslipidemia increases over a woman's lifespan, with adverse changes around the time of menopause. Menopause, and the years leading up to the final menstrual period, is a time of estrogen fluctuation and ultimately estrogen deficiency, which has been associated with proatherogenic changes in the lipid profile. Independent of aging, menopausal status is associated with elevations in serum total cholesterol, LDL cholesterol, apolipoproteins, and triglycerides, and decreases in HDL cholesterol (HDL-C). Emerging research also suggests that after menopause there is a loss of functional HDL cardioprotective properties. Early initiation of menopausal hormone therapy (MHT) confers a favorable effect on lipid profile, though this does not translate into improved CVD outcomes and therefore guidelines do not indicate it for primary or secondary prevention of CVD. At the time of menopause, special consideration should be given to women with conditions more associated with CVD, including polycystic ovarian syndrome, premature menopause, early menopause, premature ovarian insufficiency, and familial hypercholesterolemia. Statins remain the mainstay of dyslipidemia therapy, though novel lipid-lowering agents are emerging. This review provides an overview of lipid alterations observed during the menopausal transition, summarizes the current evidence on the role of estrogen and progestogen on lipids, identifies special populations of women at especially high risk for lipid dysregulation at menopause, and describes approaches to the screening and treatment of midlife women.

Abstract
Background: Pregnancy is associated with physiological changes to meet the metabolic demands of the growing fetus. To understand adverse pregnancy outcomes it is important to establish vascular changes throughout pregnancy. We examined longitudinal changes in vascular measurements from prepregnancy through postpartum. Materials and Methods: Seventy women planning to conceive in Ulaanbaatar, Mongolia enrolled in this prospective study. Within 6 months, 44 (63%) had conceived; of which 36 (82%) delivered. Ten (28%) developed complex pregnancies and were analyzed separately. Vascular measures included central systolic blood pressure (cSBP), central diastolic blood pressure (cDBP), augmentation index corrected for heart rate of 75 beats/minute (AIx-75), and pulse wave velocity (PWV). Measurements were performed at prepregnancy, second trimester (22-24 weeks), third trimester (34-36 weeks), and 2 months postpartum. Missing values (n = 0-6 per time period) were replaced by multiple imputation. A repeated measures analysis of variance analyzed changes within individual women over the four time points adjusted for age, parity, and body mass index. Results: We observed significant reductions from prepregnancy to second trimester for mean Alx-75 (17.1%-12.6%; p = 0.006) and cSBP (91.7-86.8 mmHg; p = 0.03) but not for cDBP or PWV. Both mean AIx-75 and cSBP increased in third trimester. In the postpartum, cSBP returned to prepregnancy levels, whereas AIx-75 exceeded prepregnancy levels, although this fell short of significance (p = 0.09). Similar vascular patterns were observed in women with complex pregnancies for AIx-75; however, PWV increased from the second trimester and remained higher through postpartum, although not significant. Conclusion: In Mongolian women, we observed a decrease in AIx-75 and cSBP from prepregnancy through second trimester, which resolved postpartum. These results provide an understanding of changes across pregnancies in an Asian country. Future studies should assess vascular changes across pregnancies to determine if it can predict conditions such as pre-eclampsia.

Abstract
Background Ischemia with no obstructive coronary artery disease is a condition associated with major adverse cardiovascular outcomes. To date, there are no specific American Heart Association or American College of Cardiology guidelines. The objective of this survey is to better understand the clinical practice and knowledge gaps that exist nationally. Methods and Results Participant-specific links for a survey with 11 questions and 3 reminders were sent between September and October 2020 to the American College of Cardiology CardioSurve Panel. The panel consist of randomly selected cardiologists (n=437) who represent the current profile of the American College of Cardiology US membership. The survey received a 30% response rate. Of the 172 respondents, 130 (76%) indicated that they have treated patients with ischemia with no obstructive coronary artery disease. Although the majority (69%) are generally confident in their ability to manage this condition, 1 of 3 report lack of confidence or are neutral. The American College of Cardiology/American Heart Association Chronic Stable Angina Guidelines are the most commonly used reference for treating ischemia with no obstructive coronary artery disease (81%), with most cardiologists wanting additional clinical guidance, such as randomized controlled trials (61%). More than 4 of 5 cardiologists rarely or never order advanced imaging modalities to assess coronary flow reserve. Approximately 2 of 3 of respondents frequently prescribe statins (68%), aspirin (66%), calcium channel blockers (63%), and β blockers or α/β blockers (55%). However, nearly 70% never prescribe angiotensin-converting enzyme inhibitors or angiotensin receptor blockers. Conclusions This survey demonstrates heterogeneity in the management of ischemia with no obstructive coronary artery disease among US cardiologists, identifies support for guideline development, and outlines knowledge gaps for research and education in the therapeutic management of this condition.

Abstract
Background Referrals to cardiac rehabilitation (CR) remain low despite evidence showing reduction in cardiovascular mortality and hospital readmissions. Resident education and awareness may be an opportunity to address barriers to CR referrals. Methods This pilot study involves 20 internal medicine residents rotating at an ambulatory primary care clinic. Voluntary surveys were sent through an online-based survey platform. Following survey completion, residents received a 10-minute scripted lecture and an educational handout outlining CR components, availability, indications, insurance eligibility criteria, and referral process. Surveys were redistributed 2 months post-education to assess changes in mean aggregate knowledge scores and attitude ratings on a 5-point Likert scale. CR referral rates of eligible patients pre- and post-education were obtained through review of electronic medical records. Results Sixteen (80%) residents completed both pre and post surveys, and 13 (81%) reported no education on CR in the prior year. There was a significant increase in mean aggregate knowledge scores on CR components (5.1 versus 7.0, P = 0.001), insurance coverage (2.4 versus 5.6, P< 0.001), and eligible diagnoses (7.1 versus 9.9, P = 0.03) following education. Attitudes towards CR also improved following education, particularly in self-reported comfort level with explaining CR to patients (3.69 versus 2.06, P<0.001) and perceived familiarity with CR referral process (4.00 versus 2.18, P<0.001). CR referrals increased from 0% (0 out of 10 eligible patients) to 33% (3 out of 9 eligible patients) over a 2-month period before and after education, respectively (P = 0.09). Conclusions Internal medicine resident knowledge and attitudes towards CR significantly improved after formal education. Although there was a modest increase in the rates of CR referrals following resident education, this pilot study was not powered to detect statistical significance.

Abstract
Beyond conventional risk factors for cardiovascular disease, women face an additional burden of sex-specific risk factors. Key stages of a woman's reproductive history may influence or reveal short- and long-term cardiometabolic and cardiovascular trajectories. Early and late menarche, polycystic ovary syndrome, infertility, adverse pregnancy outcomes (eg, hypertensive disorders of pregnancy, gestational diabetes, preterm delivery, and intrauterine growth restriction), and absence of breastfeeding are all associated with increased future cardiovascular disease risk. The menopause transition additionally represents a period of accelerated cardiovascular disease risk, with timing (eg, premature menopause), mechanism, and symptoms of menopause, as well as treatment of menopause symptoms, each contributing to this risk. Differences in conventional cardiovascular disease risk factors appear to explain some, but not all, of the observed associations between reproductive history and later-life cardiovascular disease; further research is needed to elucidate hormonal effects and unique sex-specific disease mechanisms. A history of reproductive risk factors represents an opportunity for comprehensive risk factor screening, refinement of cardiovascular disease risk assessment, and implementation of primordial and primary prevention to optimize long-term cardiometabolic health in women.

Abstract
AIM To determine the relationship between coronary vascular dysfunction and history of migraines in women with suspected ischemia and no obstructive coronary arteries (INOCA). METHODS In the Women's Ischemia Syndrome Evaluation-Coronary Vascular Dysfunction study, 402 women with suspected INOCA answered baseline angina questionnaires, including the Seattle Angina Questionnaire (SAQ). Coronary function testing (CFT) performed in a subgroup of 252 women evaluated for nonendothelial and endothelial-dependent coronary vascular function. Wilcoxon rank sum test, t-test, and linear regression models were performed. RESULTS Of the 252 women who underwent CFT, 126 (50%) women reported migraine history. Compared to women who reported no migraines, women with migraines were younger and more were premenopausal. They had more angina at rest, with strong emotions, and hot/cold temperatures, as well as angina that wakes them from sleep (P < 0.05 for all). Women with migraines also scored worse on SAQ angina frequency and quality of life P < 0.01 for both). There was no difference in prevalence of coronary vascular dysfunction in the two groups. In addition, linear regression models demonstrated no significant age-adjusted differences in absolute CFT variables. CONCLUSION Among women with suspected INOCA, migraine history is prevalent and women with migraines have worse angina compared to those without migraines. Coronary vascular dysfunction diagnosed by CFT does not appear to relate to migraine history.

Abstract
Study objective Women with ischemia and no obstructive coronary artery disease (INOCA) are at increased risk for heart failure (HF) hospitalizations, which is predominantly HF with preserved ejection fraction (HFpEF). We aimed to identify predictors for the development of heart failure HF in a deeply phenotyped cohort of women with INOCA and long-term prospective follow-up. Design setting and participants Women enrolled in the NHLBI-sponsored Women's Ischemia Syndrome Evaluation (WISE) were evaluated for baseline characteristics including clinical history, medications, physical exam, laboratory data and angiographic data. Using a multivariate Cox analysis, we assessed the association between baseline characteristics and the occurrence of HF hospitalizations in 493 women with evidence of ischemia but no obstructive coronary disease, no prior history of HF, and available follow-up data. Results During a median follow-up of 6-years, 18 (3.7%) women were hospitalized for HF. Diabetes mellitus and tobacco use were associated with HF hospitalization. In a multivariate analysis adjusting for known HFpEF predictors including age, diabetes, hypertension, tobacco use, and statin use, novel predictive variables included higher resting heart rate, parity and IL-6 levels and lower coronary flow reserve (CFR) and poor functional status. Conclusions There is a considerable incidence of HF hospitalization at longer term follow-up in women with INOCA. In addition to traditional risk factors, novel risk variables that independently predict HF hospitalization include multi-parity, high IL-6, low CFR, and poor functional status. These novel risk factors may be useful to understand mechanistic pathways and future treatment targets for prevention of HFpEF.

Abstract
ABSTRACT The menopause transition is associated with adverse changes to the lipid profile. Although there are no specific treatment guidelines for women, current evidence supports the use of statin therapy in women with 1) established clinical atherosclerotic cardiovascular disease (ASCVD); 2) primary hypercholesterolemia, with low-density lipoprotein cholesterol of 190 mg/dL (4.9 mmol/L) or higher; 3) diabetes mellitus regardless of ASCVD risk category (ages 40-75 y); and 4) for primary prevention of ASCVD in women at high risk (10-y risk, ≥20%) or intermediate risk (10-y risk, ≥7.5-20%) with the presence of guideline-derived risk enhancers (age 40-75 y) such as premature menopause or a history of preeclampsia.

Abstract
CONTEXT This mini-review provides an overview of menopausal hormone therapy (HT) and cardiovascular disease (CVD) risk, with a focus on the role of hormone formulation, dose, and route of delivery. METHODS This summary is based on authors' knowledge in the field of menopausal HT and supplemented by a PubMed search using the terms "menopause hormone therapy," "transdermal," "estradiol," "conjugated estrogens," "bioidentical," "cardiovascular disease," "lipoproteins," "glucose," "progestogens," "low dose." RESULTS Available evidence indicates that oral unopposed estrogens have a favorable effect on lipoprotein levels, glycemia, insulin, and CVD risk; however, the addition of progestogens blunts the lipid-related effects. The progestogen with the smallest attenuating effect is micronized progesterone. Transdermal estrogens have less effect on coagulation, inflammation, and lipids than oral estrogens and observational studies suggest they pose a lower risk of venous thromboembolism and stroke than oral estrogens. Clinical effects of hormones were not consistently dose dependent. CONCLUSIONS Although HT continues to have an important role in menopause management, it is not recommended for primary or secondary CVD prevention. Different formulations, doses, and routes of delivery of HT have different effects on cardiometabolic markers and risks of clinical CVD events. However, long-term trials evaluating clinical outcomes with transdermal and other alternate HT regimens are limited.

Abstract
Background Patients with stable ischemic heart disease represent a heterogeneous population at variable risk for major adverse cardiac events (MACE). Because MACE typically occurs outside the hospital, we studied whether biometric and psychometric remote patient monitoring are associated with MACE risk biomarkers. Methods and Results In 198 patients with stable ischemic heart disease (mean age 65±11 years, 60% women), we evaluated baseline measures, including biometric (FitBit 2) and psychometric (acquired via smartphone-administered patient-reported outcomes) remote monitoring, in the PRE-MACE (Prediction, Risk, and Evaluation of Major Adverse Cardiac Events) study. In multivariable adjusted regression analyses, we examined the association of these measures with biomarkers of MACE risk, including NT-proBNP (N-terminal pro-b-type natriuretic peptide), u-hs-cTnI (ultra-high sensitivity cardiac-specific troponin I), and hs-CRP (high-sensitivity C-reactive) protein. Both biometric and psychometric measures were associated with NT-proBNP. Specifically, step count, heart rate, physical activity, global health score, and physical function score were all inversely related, whereas physical limitation score was directly related (P≤0.05 for all). However, only biometric measures (step count and heart rate) were associated with u-hs-cTnI (inversely related, P<0.05), while only the psychometric measures of physical limitation were associated with hs-CRP (directly related, P≤0.05). Conclusions In stable ischemic heart disease patients, remotely monitored measures were associated with MACE risk biomarkers. Both biometric and psychometric measures were related to NT-proBNP. In contrast, biometric measures were uniquely related to u-hs-cTnI, while psychometric indices were uniquely related to hs-CRP. Further investigation could assess the predictive value of these metrics for MACE in ischemic heart disease.

Abstract
Background: Among premenopausal women presenting with ischemia, hypothalamic hypoestrogenemia (HHE) has been associated with angiographic coronary artery disease (CAD). Further, serum amyloid-alpha (SAA), a marker of systemic inflammation strongly predicts future adverse cardiovascular events. We sought to relate inflammatory markers to HHE and understand if inflammation mediates relations between HHE and CAD. Methods: We assessed premenopausal women not on exogenous hormones undergoing coronary angiography for suspected ischemia. HHE was defined as estradiol<50 pg/ml, luteinizing hormone<10 IU/l and follicle stimulating hormone<10 IU/l. Serum inflammatory markers, reproductive hormones, and angiographic CAD were measured. Results: Overall, 40 (31%) of the 127 women had HHE with similar age and body mass index compared to no HHE (p=0.48 and p=0.77, respectively). Women with HHE had lower estradiol compared to no HHE (30.4+11.7 vs 112.5+62.4 pg/ml, p<0.0001). There were no significant differences between high sensitivity C-reactive protein (hsCRP) (0.86 ± 1.45 vs 0.65 ± 1.17, p=0.5211) and interleukin 6 (IL-6) (4.95 ± 6.06 vs 3.90 ± 3.90, p=0.2358). However, HHE women had significantly higher SAA compared to no HHE (4.44+13.5 vs 0.94+2.37, p=0.0495). Conclusion: Among premenopausal women undergoing coronary angiography for suspected myocardial ischemia, SAA levels were significantly elevated in women with HHE, suggesting that inflammation may serve as a mediator between HHE and CAD. Further investigation relative to inflammation as a treatment target in this cohort may be warranted.

Abstract
Background: Spontaneous preterm delivery (sPTD) is associated with a twofold increased risk of future maternal cardiovascular disease. We hypothesized that women with sPTD would demonstrate greater vascular dysfunction postpartum compared to women with term delivery. Materials and Methods: In a case-controlled, matched pilot study, we enrolled 20 women with sPTD (gestation ≤34 weeks), and 20 term control women (gestation ≥39 weeks) were matched for age (±5 years), parity, ethnicity, and route of delivery. Vascular function, serum lipids, C-reactive protein, and interleukin-6 were completed within 24-72 hours postpartum. Statistical analysis included paired t-tests based on match and mixed effects linear regression models and adjusted for potential confounders. Results: The mean age for sPTD and term controls was 33 ± 6 years and 32 ± 6 years, respectively. Women with sPTD had significantly lower augmentation index-75 (24.1% ± 16.1% vs. 39.9% ± 15.2%, p = 0.001) and central pulse pressure (29.1 ± 5.4 mmHg vs. 34.6 ± 4.7 mmHg, p = 0.004), but no difference in pulse wave velocity (5.1 ± 1.6 m/s vs. 5.6 ± 1.5 m/s, p = 0.12) compared to controls. Women with sPTD had significantly lower high-density lipoprotein cholesterol (59.4 ± 12.5 mg/dL vs. 67.6 ± 13.1 mg/dL, p = 0.035) compared to controls. Analysis of chorioamnionitis and magnesium sulfate did not alter the results. Conclusions: Women with sPTD have signs of lower smooth muscle tone in the early postpartum period compared to women with term delivery. Further research is required to understand mechanistic pathways in sPTD and future maternal cardiovascular disease risk.

Abstract
Background Previous studies have reported an association between the timing of menarche and cardiovascular disease (CVD). However, emerging studies have not examined the timing of menarche in relation to role of estrogen over a lifetime and major adverse cardiac events (MACE). Methods and Results A total of 648 women without surgical menopause undergoing coronary angiography for suspected ischemia in the WISE (Women's Ischemia Syndrome Evaluation) study were evaluated at baseline and followed for 6 years (median) to assess major adverse CVD outcomes. MACE was defined as the first occurrence of all‐cause death, nonfatal myocardial infarction, nonfatal stroke, or heart failure hospitalization. Age at menarche was self‐reported and categorized (≤10, 11, 12, 13, 14, ≥15 years) with age 12 as reference. Total estrogen time and supra–total estrogen time were calculated. Cox regression analysis was performed adjusting for CVD risk factors. Baseline age was 57.9 ± 12 years (mean ± SD), body mass index was 29.5 ± 6.5 kg/m2, total estrogen time was 32.2 ± 8.9 years, and supra–total estrogen time was 41.4 ± 8.8 years. MACE occurred in 172 (27%), and its adjusted regression model was J‐shaped. Compared with women with menarche at age 12 years, the adjusted MACE hazard ratio for menarche at ≤10 years was 4.53 (95% CI 2.13‐9.63); and at ≥15 years risk for MACE was 2.58 (95% CI, 1.28‐5.21). Conclusions History of early or late menarche was associated with a higher risk for adverse CVD outcomes. These findings highlight age at menarche as a potential screening tool for women at risk of adverse CVD events. Clinical Trial Registration URL: http://www.clinicaltrials.gov.

Abstract
BACKGROUND Coronary microvascular dysfunction (CMD) is associated with adverse cardiovascular outcomes. Coronary microvascular dysfunction is observed in women of childbearing age, however, the frequency of adverse pregnancy outcomes (APO) is unknown. CASE SUMMARY Women previously enrolled in a single centre prospective CMD registry diagnosed using invasive coronary reactivity testing were included. Among 279 women enrolled, 5 of 47 (10.6%) of childbearing age (18-44 years) subsequently became pregnant, representing a fertility rate of 36.8 births per 1000 women-years. None had history of hypertension, diabetes, or smoking. Four (80%) had a history of prior spontaneous miscarriage. Median age at CMD diagnosis was 32 years (IQR: 32-35). During pregnancy, most reported stable or improved angina, while one reported increased angina frequency, an emergency room visit and accelerated anti-anginal therapy. None experienced gestational hypertension, diabetes, pre-eclampsia, myocardial infarction, or death. Two (40%) experienced APO of preterm delivery and small neonate for gestational age. Following pregnancy, angina severity scores, and/or functional capacity decreased in three women (60%). DISCUSSION In this first case-series of five women with CMD who became pregnant, increased angina and accelerated care during pregnancy and post-partum was not commonly observed. Fertility rates were lower than the national average, while prior spontaneous miscarriage and subsequent APO were higher. Further studies are warranted to understand and manage pregnancy in women with CMD, as well as the impact of pregnancy on longer term angina, functional capacity, and outcomes.

Abstract
Sex differences in cardiovascular diseases can be classified as those which are specific to one sex and those that differ in incidence, prevalence, etiology, symptomatology, response to treatment, morbidity, and mortality in one sex compared to the other. All sex differences in cardiovascular conditions have their basis in the combined expression of genetic and hormonal differences between women and men. This chapter addresses how understanding basic mechanisms of hormone responses, imaging diagnostics, and integration of genomics and proteomics has advanced diagnosis and improved outcomes for cardiovascular conditions, apart from those related to pregnancy that are more prevalent in women. These conditions include obstructive coronary artery disease, coronary microvascular dysfunction, spontaneous coronary artery dissection, diseases of the cardiac muscle including heart failure and takotsubo cardiomyopathy, and conditions related to neurovascular dysregulation including hot flashes and night sweats associated with menopause and effects of exogenous hormones on vascular function. Improvement in technologies allowing for noninvasive assessment of neuronally mediated vascular reactivity will further improve our understanding of the basic etiology of the neurovascular disorders. Consideration of sex, hormonal status, and pregnancy history in diagnosis and treatment protocols will improve prevention and outcomes of cardiovascular disease in women as they age.

Abstract
Cardiovascular disease (CVD) risk factors are well established. However, little is known about a woman's cardiovascular response to pregnancy, which appears to be an early marker of future maternal CVD risk. Spontaneous preterm delivery (sPTD) has been associated with a ≤3-fold increased risk of maternal CVD death later in life compared with having a term delivery. This review focuses on 3 key areas to critically assess the association of sPTD and future maternal CVD risk: (1) CVD risk factors, (2) inflammatory biomarkers of interest, and (3) specific forms of vascular dysfunction, such as endothelial function and arterial stiffness, and mechanisms by which each may be linked to sPTD. The association of sPTD with subsequent future maternal CVD risk suggests that a woman's abnormal response to pregnancy may serve as her first physiological stress test. These findings suggest that future research is needed to understand why women with sPTD may be at risk for CVD to implement effective interventions earlier in a woman's life.

Daily Activity Measured With Wearable Technology as a Novel Measurement of Treatment Effect in Patients With Coronary Microvascular Dysfunction: Substudy of a Randomized Controlled Crossover Trial. JMIR Res Protoc 2017; 6:e255.

Abstract
Background Digital wearable devices provide a “real-world” assessment of physical activity and quantify intervention-related changes in clinical trials. However, the value of digital wearable device-recorded physical activity as a clinical trial outcome is unknown. Objective Because late sodium channel inhibition (ranolazine) improves stress laboratory exercise duration among angina patients, we proposed that this benefit could be quantified and translated during daily life by measuring digital wearable device-determined step count in a clinical trial. Methods We conducted a substudy in a randomized, double-blinded, placebo-controlled, crossover trial of participants with angina and coronary microvascular dysfunction (CMD) with no obstructive coronary artery disease to evaluate the value of digital wearable device monitoring. Ranolazine or placebo were administered (500-1000 mg twice a day) for 2 weeks with a subsequent 2-week washout followed by crossover to ranolazine or placebo (500-1000 mg twice a day) for an additional 2 weeks. The outcome of interest was within-subject difference in Fitbit Flex daily step count during week 2 of ranolazine versus placebo during each treatment period. Secondary outcomes included within-subject differences in angina, quality of life, myocardial perfusion reserve, and diastolic function. Results A total of 43 participants were enrolled in the substudy and 30 successfully completed the substudy for analysis. Overall, late sodium channel inhibition reduced within-subject daily step count versus placebo (mean 5757 [SD 3076] vs mean 6593 [SD 339], P=.01) but did not improve angina (Seattle Angina Questionnaire-7 [SAQ-7]) (P=.83). Among the subgroup with improved angina (SAQ-7), a direct correlation with increased step count (r=.42, P=.02) was observed. Conclusions We report one of the first studies to use digital wearable device-determined step count as an outcome variable in a placebo-controlled crossover trial of late sodium channel inhibition in participants with CMD. Our substudy demonstrates that late sodium channel inhibition was associated with a decreased step count overall, although the subgroup with angina improvement had a step count increase. Our findings suggest digital wearable device technology may provide new insights in clinical trial research.

Mental stress peripheral vascular reactivity is elevated in women with coronary vascular dysfunction: Results from the NHLBI-sponsored Cardiac Autonomic Nervous System (CANS) study. Int J Cardiol 2017; 251:8-13.

Abstract
BACKGROUND Women with chest pain, ischemia, and no obstructive coronary artery disease often have coronary vascular dysfunction (CVaD). Peripheral vascular reactivity to mental stress may contribute mechanistic understanding of stress-induced ischemia in women with CVaD. METHODS 62 women (41 CVaD and 21 controls) underwent mental stress testing (MST) with anger recall, mental arithmetic, and forehead cold pressor (COP) challenge. Emotional arousal was measured (Likert scale). Reactive hyperemia index (RHI) was calculated before and after MST by peripheral arterial tonometry (PAT). Stress PAT ratio (SPR) of pulse amplitude during stress to rest was obtained to measure vasoconstriction. Wilcoxson rank sum test was used for analysis. RESULTS Mean age of CVaD and control groups was 58±9 and 55±10years (p=0.73). Baseline RHI correlated with coronary endothelial function (r=0.36, p=0.03) and inversely with RHI change post-MST (r=-0.51, p<0.001). During MST, 10% of controls reported chest pain vs. 41% of CVaD subjects (p=0.01). RHI did not change significantly after MST in either group. CVaD subjects had lower SPR vs. controls during mental arithmetic (0.54 [0.15, 1.46] vs. 0.67 [0.36, 1.8], p=0.039), not evident in the other tasks. Vasoconstriction inversely correlated with anxiety (r=-3.4, p=0.03), frustration (r=-0.37, p=0.02), and feeling challenged (r=-0.37, p=0.02) in CVaD but not controls. CONCLUSIONS Mental stress peripheral vascular reactivity is elevated in women with CVaD compared to controls. Elevated vascular reactivity may be one contributor to stress-induced chest pain in CVaD. Interventions that modulate vasoconstrictive responses may be of benefit and should be tested in clinical trials in women with CVaD.

Abstract
OBJECTIVE Signs and symptoms of ischemia but no obstructive coronary artery disease (CAD) is often a diagnostic dilemma in women. The use of stress cardiac magnetic resonance imaging (CMRI) for advanced diagnostic assessment in these patients is a non-ionizing radiation option, but the diagnostic utility in this population is unknown. We examined the diagnostic role of stress CMRI in our patient population of these women. METHODS We analyzed 113 consecutive female patients from 2/2006-11/2007 who had prior cardiac evaluations for signs and symptoms of ischemia but no obstructive CAD who underwent stress CMRI, which included anatomic, functional, adenosine stress perfusion and delayed enhancement imaging. RESULTS The population demographics of 113 women included a mean age of 55±12.2 years with an average body mass index (BMI) of 25 ± 4.5. Overall, 43% had hypertension, 4% had diabetes and 3% were smokers. Overall, 80/113 (70%) demonstrated abnormal stress CMRI results. The majority of patients demonstrated findings consistent with subendocardial perfusion abnormalities suggestive of coronary microvascular dysfunction (CMD). Of note, 3 patients (4%) were diagnosed with congenital coronary anomalies or cardiomyopathy not detected in prior cardiac evaluations. CONCLUSION Among women with signs and symptoms of ischemia but no obstructive CAD, stress CMRI is frequently abnormal and is valuable in diagnosis of CMD. Stress CMRI appears useful for advanced diagnostic assessment in these diagnostically challenged patients.

Typical angina is associated with greater coronary endothelial dysfunction but not abnormal vasodilatory reserve. Clin Cardiol 2017; 40:886-891.

Abstract
Background Typical angina (TA) is defined as substernal chest pain precipitated by physical exertion or emotional stress and relieved with rest or nitroglycerin. Women and elderly patients are usually have atypical symptoms both at rest and during stress, often in the setting of nonobstructive coronary artery disease (CAD). Hypothesis To further understand this, we performed subgroup analysis comparing subjects who presented with TA vs nontypical angina (NTA) using baseline data of patients with nonobstructive CAD and coronary microvascular dysfunction (CMD) enrolled in a clinical trial. Methods 155 subjects from the RWISE study were divided into 2 groups based on angina characteristics: TA (defined as above) and NTA (angina that does not meet criteria for TA). Coronary reactivity testing (responses to adenosine, acetylcholine, and nitroglycerin), cardiac magnetic resonance–determined myocardial perfusion reserve index (MPRI), baseline Seattle Angina Questionnaire (SAQ), and Duke Activity Status Index (DASI) scores were evaluated. Results The mean age was 55 ± 10 years; Overall, 30% of subjects had TA. Baseline shortness of breath, invasively assessed acetylcholine‐mediated coronary endothelial function, and SAQ score were worse in the TA group (all P < 0.05), whereas adenosine‐mediated coronary flow reserve, MPRI, and DASI score were similar to the NTA group. Conclusions Among subjects with CMD and no obstructive CAD, those with TA had more angina pectoris, shortness of breath, and worse quality of life, as well as more severe coronary endothelial dysfunction. Typical angina in the setting of CMD is associated with worse symptom burden and coronary endothelial dysfunction. These results indicate that TA CMD subjects represent a relatively new CAD phenotype for future study and treatment trials.

Abstract
The menstrual cycle is a reproductive vital sign and provides insight into hormonal imbalance as well as pregnancy. The significance of estrogen, however, extends beyond fertility and plays a role on tissues and organs throughout the body. Functional hypothalamic amenorrhea is a common form of secondary amenorrhea resulting in estrogen deficiency in young premenopausal women. While reversible, the cause of this disorder is related to psychological stress, excessive exercise, disordered eating or a combination of these factors resulting in suppression of the hypothalamic–pituitary–ovarian axis. The resulting loss of estrogen has profound effects on many systems throughout the body including cardiac, skeletal, psychological and reproductive. Often, these young women are the ‘walking well’ as they do not have bothersome symptoms of low estrogen and are unaware of the consequences of estrogen deficiency. This review focuses on the health consequences of hypothalamic amenorrhea, current research and available treatment options.

Abstract
Background:
Since late Na channel inhibition (ranolazine) improves exercise duration in the stress laboratory among angina patients, we questioned if this benefit would translate to impact step-count during daily life assessed by a "wearable" device.
Methods:
We conducted a pilot substudy within a randomized, double-blinded, placebo-controlled, cross-over trial of subjects with angina, non-obstructive coronary artery disease and coronary microvascular dysfunction. Ranolazine was administered (500-1000mg BID for 2 weeks). The outcome of interest was difference in Fitbit Flex daily step-count during weeks 2 of ranolazine or placebo treatment. Other outcomes included angina, quality of life, ischemia, diastolic function.
Results:
30 subjects were analyzed. Overall, late Na channel inhibition reduced daily step-count vs. placebo (5757 +/- 3076 vs. 6593 +/- 3393, p=0.01) and did not improve angina. However, among those with improved angina (SAQ-7 improvement), a direct correlation with increased step-count (0.42, p=0.02) was observed, most due to typical angina (0.57, p=0.05) (Fig).
Conclusions:
We report the "first" data set from a wearable monitor to measure step-count in a controlled late Na channel inhibition trial. Our results suggest short-term late Na channel inhibition (ranolazine) does not increase step-count during daily life.

Abstract
Angina, heart failure with preserved ejection fraction (HFpEF) and coronary microvascular dysfunction (CMD) in the absence of obstructive coronary artery disease (CAD) are more common in women and are associated with adverse cardiovascular prognosis. Cardiac magnetic resonance imaging (CMRI) is established for assessment of left ventricular (LV) morphology and systolic function and is increasingly used to assess myocardial perfusion and diastolic function. Indeed, stress CMRI allows measurement of myocardial perfusion reserve index (MPRI) using semi-quantitative techniques, and quantification of LV volumetric filling patterns provides valuable insight into LV diastolic function. The utility of these two techniques remains limited, because reference control values for MPRI and LV diastolic function in asymptomatic middle-aged, women have not previously been established. To address this limitation, we recruited twenty women, without clinical cardiovascular disease or cardiovascular risk factors, with normal maximal Bruce protocol exercise treadmill testing. Subjects underwent CMRI (1.5 tesla) using a standardized protocol of adenosine stress and rest perfusion and LV cinematic imaging. Commercially available with automated CMRI segmentation was used for calculation of MPRI, LV filling profiles, and ejection fraction. Mean age was 54±9 years and mean body mass index was 25±4 kg/m(3). The exercise treadmill testing results demonstrated a normotensive group with normal functional capacity and hemodynamic response. We report reference control values for semi-quantitative MPRI as well as measures of LV systolic and diastolic function including ejection fraction, stroke volume, peak filling rate (PFR), PFR adjusted for end-diastolic volume (EDV) and stroke volume, time to PFR, and EDV index. The data herein provide reference values for MPRI and diastolic function in a cohort of healthy, middle-aged of women. These reference values may be used for comparison with a variety of patient populations, including women with CMD and HFpEF.

Abstract
Aims The mechanistic basis of the symptoms and signs of myocardial ischaemia in patients without obstructive coronary artery disease (CAD) and evidence of coronary microvascular dysfunction (CMD) is unclear. The aim of this study was to mechanistically test short-term late sodium current inhibition (ranolazine) in such subjects on angina, myocardial perfusion reserve index, and diastolic filling. Materials and results Randomized, double-blind, placebo-controlled, crossover, mechanistic trial in subjects with evidence of CMD [invasive coronary reactivity testing or non-invasive cardiac magnetic resonance imaging myocardial perfusion reserve index (MPRI)]. Short-term oral ranolazine 500–1000 mg twice daily for 2 weeks vs. placebo. Angina measured by Seattle Angina Questionnaire (SAQ) and SAQ-7 (co-primaries), diary angina (secondary), stress MPRI, diastolic filling, quality of life (QoL). Of 128 (96% women) subjects, no treatment differences in the outcomes were observed. Peak heart rate was lower during pharmacological stress during ranolazine (−3.55 b.p.m., P < 0.001). The change in SAQ-7 directly correlated with the change in MPRI (correlation 0.25, P = 0.005). The change in MPRI predicted the change in SAQ QoL, adjusted for body mass index (BMI), prior myocardial infarction, and site (P = 0.0032). Low coronary flow reserve (CFR <2.5) subjects improved MPRI (P < 0.0137), SAQ angina frequency (P = 0.027), and SAQ-7 (P = 0.041). Conclusions In this mechanistic trial among symptomatic subjects, no obstructive CAD, short-term late sodium current inhibition was not generally effective for SAQ angina. Angina and myocardial perfusion reserve changes were related, supporting the notion that strategies to improve ischaemia should be tested in these subjects.
