Advances in Cardiovascular Health in Women over the Past Decade: Guideline Recommendations for Practice

Spanish validation of the cardiac self-efficacy scale: a gender invariant measure

The aim is to validate the Spanish version of the Cardiac Self-Efficacy (S-CSE) Scale by examining its psychometric properties and to test the invariance for women and men. Two groups - 722 and 522- of patients completed the S-CSE Scale and other psychosocial measures during a medical revision several months after being diagnosed with cardiovascular disease. Construct validity was psychometrically evaluated using exploratory factor analysis (EFA) with a split of the first sample and confirmatory factor analysis (CFA) with a second split of the same sample. Scale structure was confirmed using the second sample. Convergent, discriminant, and external validity were tested. Results revealed that the S-CSE Scale was represented by three dimensions (control symptoms, control illness, maintain functioning) obtaining excellent reliability indexes and it appeared to be invariant for women and men. The S-CSE scale is a useful tool for monitoring the general well-being of these patients to promote individualized interventions.

Gender Bias in Cardiovascular Disease Prevention, Detection, and Management, with Specific Reference to Coronary Artery Disease

Even though cardiovascular disease (CVD) kills more women than men each year and remains a leading cause of death in women, it is a common misconception that women are less likely to develop CVD. Considerable sex difference exists between men and women with regard to prevention, investigations, and management of CVD. Coronary artery disease (CAD) is a major contributor to CVD morbidity and mortality and hence is specifically addressed in this article. With an explosive increase in the incidence of conventional risk factors for coronary artery disease in India, there has been an alarming increase in women's coronary events as much as men. A false sense of gender-based protection by estrogen leads to less aggressive and late prevention or management strategies that contribute to women's CAD. Metabolic syndrome (MetS) is an important contributor to future development of CAD and is also an indicator for earlier interventions for prevention. Due to physical inactivity and central obesity, MetS is more prevalent in women, especially postmenopausal. With estrogen loss, menopause marks a critical cardiovascular biological transition, with a significantly increased CVD risk in women aged >55 years. Certain female-specific risk factors, such as history of polycystic ovarian syndrome, pregnancy-induced hypertension, and gestational diabetes, also seem to play an essential role in the development of CVD in later life. Certain vascular and biological factors, such as smaller coronary vessel size, higher prevalence of small vessel disease, and lesser development of collateral flow, also play an important role. This review article is an attempt to provide important information on gender differences in CVD with specific emphasis on CAD.

Influence of hormonal contraceptives on peripheral vascular function and structure in premenopausal females: a review

Hormonal contraceptives are one of the most widely used prescriptions for premenopausal women worldwide. Although the risk of venous and arterial cardiovascular events (e.g., deep vein thrombosis, arterial clotting) with hormonal contraceptives, specifically oral contraceptive pills, has been established, the literature on early risk indicators, such as peripheral vascular structure and function has yet to be consolidated. The purpose of this review is to summarize literature examining the impact of different hormonal contraceptives on vascular function and structure, including consideration of phasic differences within a contraceptive cycle, and to propose future directions for research. It is evident that hormonal contraceptive use appears to impact both macrovascular and microvascular endothelial function, with phasic differences in some contraceptive types dependent on progestin type, the ratio of ethinyl estradiol-to-progestin, and route of administration. However, hormonal contraceptives do not appear to impact smooth muscle function in the macrovasculature or microvasculature, arterial stiffness, or vascular structure. Underlying mechanisms for observed impacts and areas of future research are discussed. This review provides timely consolidation of research examining hormonal contraceptives and peripheral vascular function and structure and provides guidance on considerations for hormonal contraceptive use in study design.

The Role of Emotional Regulation and Affective Balance on Health Perception in Cardiovascular Disease Patients According to Sex Differences

One of the challenges of aging is the increase of people with chronic diseases, such as cardiovascular disease (CVD). Men and women experience the disease differently. Therefore, it has an impact on how CVD is treated and its outcomes. This research analyzed the relationship between psychosocial variables and health promotion among cardiovascular patients, paying special attention to sex differences. A longitudinal study with cardiovascular patients (747 in phase 1 (122 women) and 586 in phase 2 (83 women)) was carried out. Participants were evaluated based on their sociodemographic characteristics, affective balance, regulatory negative affect self-efficacy, stress and anxiety regulation strategies, and perceived global health. Results showed that men presented significantly higher scores in positive affect, affective balance, and self-efficacy to regulate negative emotions, while women presented significantly higher scores in negative affect and the use of passive strategies to cope with stressful situations. Regression analyses showed that all psychological variables studied in phase 1 were significant predictors of health perception in phase 2. According to the results, it is necessary to include strategies to improve cardiovascular health through education and emotional regulation, with a gender focus.

The Clinical Utility of a Precision Medicine Blood Test Incorporating Age, Sex, and Gene Expression for Evaluating Women with Stable Symptoms Suggestive of Obstructive Coronary Artery Disease: Analysis from the PRESET Registry

Background: Evaluating women with symptoms suggestive of coronary artery disease (CAD) remains challenging. A blood-based precision medicine test yielding an age/sex/gene expression score (ASGES) has shown clinical validity in the diagnosis of obstructive CAD. We assessed the effect of the ASGES on the management of women with suspected obstructive CAD in a community-based registry.

Materials and Methods: The prospective PRESET (A Registry to Evaluate Patterns of Care Associated with the Use of Corus^® CAD in Real World Clinical Care Settings) Registry (NCT01677156) enrolled 566 patients presenting with symptoms suggestive of stable obstructive CAD from 21 United States primary care practices from 2012 to 2014. Demographics, clinical characteristics, and referrals to cardiology or further functional and/or anatomical cardiac studies after ASGES testing were collected for this subgroup analysis of women from the PRESET Registry. Patients were followed for 1-year post-ASGES testing.

Results: This study cohort included 288 women with a median age 57 years. The median body mass index was 29.2, with hyperlipidemia and hypertension present in 48% and 43% of patients, respectively. Median ASGES was 8.5 (range 1–40), with 218 (76%) patients having low (≤15) ASGES. Clinicians referred 9% (20/218) low ASGES versus 44% (31/70) elevated ASGES women for further cardiac evaluation (odds ratio 0.14, p < 0.0001, adjusted for patient demographics and clinical covariates). Across the score range, higher ASGES were associated with a higher likelihood of posttest cardiac referral. At 1-year follow-up, low ASGES women experienced fewer major adverse cardiac events than elevated ASGES women (1.3% vs. 4.2% respectively, p = 0.16).

Conclusions: Incorporation of ASGES into the diagnostic workup demonstrated clinical utility by helping clinicians identify women less likely to benefit from further cardiac evaluation.

Modeling Health Disparities and Outcomes in Disenfranchised Populations

The Health Disparities and Outcomes (HDO) model originally created to explain the complexity of obtaining healthcare in rural settings has been revised and updated using emerging theoretical models of adversity and inequity and two decades of empirical work by the authors. With a strong orientation to explaining population-based health inequities, the HDO is applied to individuals with Serious Mental Illness (SMI), to explain their high rates of morbidity and mortality compared to the general population. Individual-, community-, and system-level factors that reflect an understanding of life-long risk, accrued hazards associated with multiple and intersecting disadvantages, and difficulty obtaining healthcare that meets accepted standards are described. The revised HDO can be applied to populations with disproportionate health challenges to identify multi-level factors that affect illness trajectory and overall health outcomes.

Gender Differences in Outcomes Following a Pain-Free, Home-Based Exercise Program for Claudication

Background: Peripheral artery disease (PAD) is a common cardiovascular pathology that affects mobility. In previous research, supervised exercise, a recommended treatment for claudication, was less effective in women. This study retrospectively investigated whether functional outcomes exhibit sex differences following a pain-free, home-based exercise program for PAD patients.

Materials and Methods: Patients with PAD and claudication enrolled to a structured home-based program from 2003 to 2016 were studied. The program was prescribed at the hospital and based on two daily 10-minute pain-free walking sessions at progressively increasing speed. Outcome measures, which were assessed at baseline and discharge, were pain threshold speed (PTS) and maximal (Smax) during a treadmill test and pain-free walking distance (PFWD) and total distance walked in 6 minutes (6MWD). The ankle-brachial index (ABI), program duration, and patient adherence were determined.

Results: A total of 1007 patients (women; n = 264; 26%) were enrolled. At baseline, compared to men, women exhibited similar ABI values but lower PTS and PFWD values (p < 0.001). At discharge, with similar adherence (score 3/4 ± 1 each) in both groups, superimposable improvements were observed for PTS (0.8 ± 0.8 km/h each), Smax (0.4 ± 0.5 km/h each), PFWD (women 95 ± 100; men 86 ± 104), 6MWD (women 32 ± 65; men 35 ± 58), and ABI (women 0.07 ± 0.12; men 0.06 ± 0.11) without between-group differences (confirmed after propensity analysis).

Conclusion: A personalized, structured pain-free exercise program for PAD patients performed inside the home for a few minutes a day was equally effective in both sexes. Programs favoring adherence and functional outcomes in women should be tested in prospective studies.

Reasons for dropout from cardiac rehabilitation programs in women: A qualitative study

BACKGROUND

Empirical evidence has shown that cardiac rehabilitation programs are effective in reducing morbidity and mortality, improving quality of life in patients with cardiovascular disease. Despite the benefits, women have a high cardiac rehabilitation dropout rate. Our aim was to explore women's perceptions about the reasons they faced for dropout from these programs.

METHODS

Semi-structured interviews were conducted with women (n = 10) after dropping out from three different cardiac rehabilitation centers in Spain. In addition, a focus group and a semi-structured interview with cardiovascular professionals were conducted. From a grounded theory perspective, thematic analysis was used to derive themes from interview transcripts.

RESULTS

The women were between 41 and 70 years. We identified five general themes that illustrated reasons for cardiac rehabilitation dropout: intrapersonal reasons (self-reported health, self-reported mental health, health beliefs); interpersonal reasons (family caregiver role, work conflicts); logistical reasons (transport, distance); cardiac rehabilitation program characteristics (perception of the objective of cardiac rehabilitation, exercise component, inconvenient timing, cardiac rehabilitation equipment); and health system reasons (financial assistance for transport, long waiting list). The cardiovascular professionals found barriers to cardiac rehabilitation completion similar to those found by the women.

CONCLUSIONS

In order to prevent cardiac rehabilitation dropout in women, modular and flexible programs are needed. In addition, the inclusion of primary care centers or community resources could improve cardiac rehabilitation completion in women. Psychological assessment and counseling during cardiac rehabilitation should be included as an essential part of the programs and recommended for those women with depressive symptoms. Finally, improved financial assistance for transport from the health system is essential.
