Cardiovascular Disease Management in Minority Women

Heart Disease Knowledge and Awareness in African American and Hispanic Women

OBJECTIVES

Coronary heart disease (CHD) is the leading cause of morbidity and mortality among US women. Minority women have higher rates of CHD and are more likely to experience adverse outcomes. Because of racial disparities in CHD outcomes, the purpose of this study was to assess CHD knowledge and awareness in African American and Hispanic women.

METHODS

Using a survey research design, a convenience sample of African American and Hispanic women was surveyed in their local communities. CHD knowledge, awareness, and demographic data were collected using an online survey. The survey was administered in English and Spanish using an iPad. CHD knowledge was assessed using a 7-item survey based on the American Heart Association's Life's Simple 7 brochure. CHD awareness was assessed using a 7-item survey adapted from the American Heart Association's Survey of Women's Cardiovascular Disease Awareness. CHD knowledge was scored on a scale of 0 to 7, and awareness was assessed based on responses to each question. The data analysis consisted of cross-tabulations and multivariable repeated measures analysis. We assessed differences in CHD knowledge and awareness based on race/ethnicity. We hypothesized that there would be statistically significant differences in CHD knowledge and awareness based on specific demographic factors (eg, age, income, education, health literacy).

RESULTS

A total of 100 African American (n=50) and Hispanic (n = 50) women participated in the study. Results revealed that CHD knowledge and awareness were limited for both groups. Seventy-three percent of participants (African American 66%; Hispanic 80%) did not know that CHD is the leading cause of death in women and 75% (African American 60%; Hispanic 90%) were moderately or not at all informed about CHD.

CONCLUSIONS

These findings support the need for more research on innovative strategies to improve CHD knowledge and awareness, particularly in African American and Hispanic women who are at highest risk, thereby addressing racial/ethnic and gender disparities in CHD morbidity and mortality.

Vasomotor symptoms of menopause, autonomic dysfunction, and cardiovascular disease

Cardiovascular disease (CVD), the leading cause of death among US adults, is more prevalent in menopausal females compared with age-matched males. Vasomotor symptoms of menopause (VMS; hot flashes/flushes and night sweats) are common among females undergoing menopausal transition and have been associated with elevated blood pressure (BP) and increased CVD risk. Autonomic dysregulation of BP has been posited as a contributing factor to the elevated CVD risk in menopausal females with VMS. This review includes 1) a brief overview of the relationship between VMS and CVD, 2) mechanisms of hot flushes and their potential impact on short- and long-term BP regulation, and 3) how the disruption of autonomic function associated with VMS might provide a mechanistic pathway to CVD development. Finally, this review will highlight knowledge gaps and future directions toward better understanding of hot flush physiology and VMS contributions to CVD.

Stress Reduction Strategies Used by Midlife Black Women to Target Cardiovascular Risk

BACKGROUND

Midlife black women are at a high risk for cardiovascular disease and experience higher morbidity and mortality rates. Chronic life stress contributes to the existent cardiovascular-related disparities for midlife black women.

OBJECTIVES

The purpose of this qualitative study was to describe stress reduction strategies relevant to midlife black women, identify barriers, and generate ideas for the development of a stress reduction wellness intervention for midlife black women.

METHODS

A community advisory board consisting of 11 midlife black women from the Midwest was established and charged with exploring life stress and stress-related issues for women like themselves. The community advisory board was led through a series of focus group discussions using open-ended questions focused on stress reduction strategies used by midlife black women, what kept them from incorporating stress reduction strategies into their daily routines, and what would be helpful in a stress reduction routine. Discussions were audiotaped, transcribed, coded, and analyzed using content analysis.

RESULTS

Stress reduction strategies identified included exercise, faith and prayer, self-care, sisterhood, volunteerism, and mindfulness. Barriers to adopting stress reduction behaviors included time, finances, physical limitations, health status, health insurance, and guilt. Suggested modes of delivery for an intervention included informative lectures and coaching, demonstration, team sessions, social media, and continued access.

CONCLUSIONS

Findings from this study were consistent with those from a preliminary study focused on midlife black women from the West Coast. Recommendations will inform development of a stress reduction wellness intervention for midlife black women.

Obesity and cardiovascular disease in women

As the prevalence of obesity continues to grow worldwide, the health and financial burden of obesity-related comorbidities grows too. Cardiovascular disease (CVD) is clearly associated with increased adiposity. Importantly, women are at higher risk of CVD when obese and insulin resistant, in particular at higher risk of developing heart failure with preserved ejection fraction and ischemic heart disease. Increased aldosterone and mineralocorticoid receptor activation, aberrant estrogenic signaling and elevated levels of androgens are among some of the proposed mechanisms explaining the heightened CVD risk. In addition to traditional cardiovascular risk factors, understanding nontraditional risk factors specific to women, like excess weight gain during pregnancy, preeclampsia, gestational diabetes, and menopause are central to designing personalized interventions aimed to curb the epidemic of CVD. In the present review, we examine the available evidence supporting a differential cardiovascular impact of increased adiposity in women compared with men and the proposed pathophysiological mechanisms behind these differences. We also discuss women-specific cardiovascular risk factors associated with obesity and insulin resistance.
