Women's Heart Disease: Understanding Risks, Perceptions, and Clinical Perspectives
Coronary Heart Disease Risk Factors in Women
Coronary heart disease (CHD) is the leading cause of death among women, with several risk factors contributing to its prevalence. Key risk factors include smoking, diabetes, elevated blood pressure, elevated blood lipids, and low socio-economic status. Smoking, in particular, significantly increases the risk of myocardial infarction in young women, with the risk escalating with the number of cigarettes smoked. Additionally, diabetes has a more pronounced impact on women than men, and low socio-economic status is a stronger risk factor for women.
Women's Perceptions of Heart Disease
Despite the high prevalence of CHD, many women underestimate their risk. Studies show that women often perceive breast cancer as a greater threat than heart disease, leading to a lack of early intervention and preventive measures. This misperception is compounded by societal barriers and inadequate communication between women and healthcare providers, which further hinders the adoption of health-promoting behaviors.
Clinical Perspectives on Cardiovascular Disease in Women
Cardiovascular disease (CVD) remains the leading cause of death among women in the United States, accounting for approximately one-third of female deaths. Unique aspects of cardiovascular health in women include conditions like myocardial infarction associated with nonobstructive coronary arteries, spontaneous coronary artery dissection, and stress-induced cardiomyopathy (Takotsubo Syndrome). Additionally, heart failure with preserved ejection fraction and peripheral arterial disease are more prevalent in women.
The Role of Estrogen and Hormone Replacement Therapy
The delay in the manifestation of vascular diseases in women compared to men is often attributed to the protective effects of endogenous estrogens. CHD is rare in premenopausal women but increases post-menopause. Estrogen replacement therapy has been speculated to continue this protective effect, although the benefits may have been overestimated .
Underrepresentation and Misdiagnosis in Clinical Trials
Women are often underrepresented in clinical trials, leading to a lack of sex-disaggregated diagnostic and management strategies. This underrepresentation results in delays in diagnosis, less aggressive treatment, and worse outcomes for women. The European Society of Cardiology has initiated programs to address these gaps and improve the understanding and treatment of CVD in women.
Emerging Risk Factors and the Need for Awareness
Emerging risk factors for ischemic heart disease (IHD) in women include adverse pregnancy outcomes, systemic autoimmune disorders, and psychosocial factors such as mental stress and low socio-economic status. Despite progress in awareness and treatment, heart disease remains a significant cause of mortality, with awareness of heart disease as the leading cause of death among women declining from 65% in 2009 to 44% in 2019. This decline is particularly notable among Hispanic and non-Hispanic Black women and younger women.
Conclusion
Women's heart disease is a critical public health issue that requires increased awareness, better risk factor management, and more inclusive clinical research. Addressing the unique aspects of cardiovascular health in women and improving communication between women and healthcare providers are essential steps in reducing the morbidity and mortality associated with heart disease in women.
