Gender bias takes many forms and the media perhaps more frequently reports on gendered income bias. Such as the longstanding pay gap between the average weekly full-time earnings of males and females, which predominately favours men. Currently Australia's national gender pay gap stands at 13.4 per cent. Or the end of working life disparity between the superannuation outcomes of men and women.
However, it has been apparent for many years now that the health professions, hospitals and governments carry a general societal bias against women into the healthcare sector and that bias barely rates a mention when governments establish terms of reference for parliamentary inquiries into aspects of health service delivery and outcomes.
The NSW Legislative Council Portfolio Committee No.2 - Health’s Terms of Reference for its current Inquiry Into Health Outcomes And Access To Health And Hospital Services In Rural, Regional And Remote New South Wales Health Outcomes And Access To Health And Hospital Services In Rural, Regional And Remote New South Wales is no exception to this lack of consideration of gender bias.
A bias which has the potential to disproportionally affect the health outcomes for females from low income families, those women who identify as Aboriginal or Torres Strait Islander and women living in regional, rural and remote areas.
So these articles below are a timely reminder that the existence of gender bias is indicated in Australia and also of the global scale of such bias.
Australian Institute of Health and Welfare, “Cardiovascular disease in women”, report excerpt, July 2019:
1.1 A focus on women
Much of our knowledge of heart disease is based on research conducted primarily among men (McDonnell et al. 2018), which shapes our view of how cardiovascular disease impacts the Australian population. However, it is known that there are important differences between women and men in risk factors for CVD, in symptoms, and in treatment and outcomes.
Need for greater awareness
Many women are unaware of the risk that CVD presents to their health. Their knowledge about heart attack symptoms and CVD as a cause of death is less than optimal—in 2018, for example, only one-fifth (21%) of Australian women correctly perceived heart-related causes to be the leading cause of death (Bairey Merz et al. 2017; Flink et al. 2013; Heart Foundation 2018; Hoare et al. 2017).
2 Cardiovascular disease in women
Women presenting with CVD often have different symptoms than men. These symptoms may not be recognised as CVD, thus increasing the likelihood of a missed diagnosis.
Although men with heart attack typically describe chest pain or discomfort, women are more likely to have non-chest pain symptoms such as shortness of breath, weakness, fatigue and indigestion (Mehta et al. 2016; Wenger 2013), and frequently with worse consequences (Maas et al. 2011; McDonnell et al. 2018; Pagidipati & Peterson 2016).
Women generally present with CVD later in life than do men. Older women are also more likely to have other health conditions, making their CVD more complex to diagnose and treat, which in turn can lead to worse health outcomes (Bennett et al. 2017; Saeed et al. 2017).
Physicians are more likely to underestimate CVD risk in women, and this can influence their diagnosis and treatment (Wenger 2013). Research finds that younger women aged under 55 with acute coronary syndrome are more likely to be misdiagnosed and discharged from emergency departments than men (Bairey Merz et al. 2017; Saw et al. 2014).
Differences in treatment
A number of studies have identified disparities between women and men in CVD treatment and in outcomes. Women with acute coronary syndrome tend to receive fewer medications, are less likely to have their condition treated aggressively and have fewer invasive interventions (Kuhn et al. 2014, 2015, 2017; Pagidipati & Peterson 2016; Saeed et al. 2017).
Similarly, women with ST segment elevation myocardial infarction (STEMI: a type of heart attack) are less likely to receive invasive management, revascularisation or preventive medication at discharge (Khan et al. 2018). Women with stroke are more likely to have a delay in care than men, and are less likely to receive aspirin, statins or thrombolytics (Raeisi-Giglou et al. 2017).
Healthier women
An increased recognition of gender differences in risk factors, presentation, treatment and outcomes will contribute to improving women’s cardiovascular health in Australia.
The Australian Government, the Heart Foundation, the Stroke Foundation and other key stakeholders contribute by building awareness among the public and health-care providers about the risks of CVD to women’s health.
Chronic conditions, including CVD, and preventative health are a priority for action in the National Women’s Health Strategy 2020–2030 (Department of Health 2018). The development and delivery of a national campaign to promote awareness of the different risks for and symptoms of CVD in women is a key action in the current strategy. The ongoing monitoring of the impact of CVD is an important component of policy and programme initiatives that focus on women’s health.
Australian Institute of Health and Welfare, Cardiovascular disease in Australian women — a snapshot of national statistics, June 2019:
”Cardiovascular disease is the leading cause of death in women. Decades of grassroots campaigns have helped to raise awareness about the impact of cardiovascular disease in women, and positive changes affecting women and their health have gained momentum. Despite these efforts, there has been stagnation in the overall reduction of cardiovascular disease burden for women in the past decade. Cardiovascular disease in women remains understudied, under-recognised, underdiagnosed, and undertreated. This Commission summarises existing evidence and identifies knowledge gaps in research, prevention, treatment, and access to care for women. Recommendations from an international team of experts and leaders in the field have been generated with a clear focus to reduce the global burden of cardiovascular disease in women by 2030. This Commission represents the first effort of its kind to connect stakeholders, to ignite global awareness of sex-related and gender-related disparities in cardiovascular disease, and to provide a springboard for future research.” [THE LANCET COMMISSIONS, The Lancet women and cardiovascular disease Commission: reducing the global burden by 2030, 16 May 2021]
The Lancet, 19 June 2021:
Ana Olga Mocumbi (May 2021) “Women's cardiovascular health: shifting towards equity and justice”
Cardiovascular disease in women is understudied, under-recognised, underdiagnosed, and undertreated globally, despite being the leading cause of death in women worldwide, as highlighted by a new Lancet Commission.1 Several misperceptions contribute to this neglect, notably, the persistent view that cardiovascular disease primarily affects men or only women in high-income countries and results from poor lifestyle choices. The Lancet women and cardiovascular disease Commission1 identifies disparities in prevalence and outcomes of cardiovascular disease in women worldwide, delineates the substantial impact of socioeconomic deprivation in determining these differences, and proposes strategies to address these inequities, increase sex-related research, and support integration of care and strengthening of health systems.1
From 1990 to 2019 there have been large declines in cardiovascular disease age-standardised rates of death, disability-adjusted life-years, and years of life lost.2 There have been declines in age-standardised prevalence of coronary heart disease and stroke mortality rates in men and women in most parts of the world, with greater age-specific reductions in coronary heart disease in men than in women.3
Between 2010 and 2019, the age-standardised cardiovascular disease death rate increased or stagnated in many other parts of the world, including eastern Europe and countries in central, south, and east Asia.2 In a Canadian setting, the 30-day acute myocardial infarction mortality rates declined similarly for women and men from 2000 to 2009, but women younger than 55 years had an excess mortality risk compared with men of the same age.4 Under-representation of young people in clinical studies on cardiovascular disease, as well as worse risk profile due to comorbidities, might contribute to these slow improvements. Importantly, because of women's longer life expectancy, overall deaths from cardiovascular disease are higher in women than in men, and this excess number of cardiovascular disease deaths in women is likely to increase with population ageing. Moreover, the success in declining age-standardised cardiovascular disease mortality over the past decades has been limited to countries with a high Socio-demographic Index (SDI); some countries with a low SDI had the highest cardiovascular disease mortality rate shift from men to women.2

Poverty continues to affect a considerable proportion of the world's population, determining unique patterns of non-communicable diseases, including cardiovascular disease in young women.5 In countries with a low SDI, where premature cardiovascular disease mortality is largely driven by poverty, poor access to care, and underuse of interventions of proven efficacy, women face the coexistence of an increased prevalence of cardiovascular disease, a rise in metabolic risk factors, and endemic infectious diseases such as tuberculosis, HIV/AIDS, and schistosomiasis. Furthermore, specific risk factors and conditions affect women in countries with a low SDI. Chronic exposure to biomass fuel is common in rural Africa and Asia and contributes to the burden of acute coronary events and stroke,6 affecting predominantly women; this exposure could partly explain the high occurrence of and sex differences in isolated right heart failure in non-smokers in these places.6, 7 Similarly, in poor countries women younger than 40 years are increasingly affected by neglected or poverty-related conditions, such as rheumatic heart disease and endomyocardial fibrosis.8,9 Moreover, maternal mortality remains unacceptably high. About 295 000 women died during and after pregnancy and childbirth in 2017.10 94% of these deaths occurred in low-resource settings, where the maternal mortality ratio was 462 per 100 000 livebirths versus 11 per 100 000 livebirths in high-income countries.10 Since cardiovascular disease is the leading non-obstetric cause of maternal mortality worldwide,11 one should consider the role of disparity in fertility rates, incidence of peripartum cardiomyopathy, and pre-existing uncontrolled arterial hypertension8 as potential determinants of maternal mortality. Indeed, there are a considerable number of maternal deaths due to cardiovascular disease in low-income and middle-income countries.12 Unfortunately, even in the USA, where the maternal mortality ratio was 17·4 maternal deaths per 100 000 livebirths in 2018, the maternal mortality ratio was more than double among non-Hispanic Black women (37·1 per 100 000 livebirths), with more than half of these deaths and near deaths being preventable, and cardiovascular disease being the leading cause.13 Inadequate access to quality and affordable health care along with long-standing health disparities plays a role in this disparity; additionally, social determinants of health can increase the risk of gestational diabetes, peripartum cardiomyopathy, caesarean deliveries, and future cardiovascular disease in neglected communities.
To address the gaps highlighted by this Commission, current knowledge must be used to achieve health equity so that no one is disadvantaged from attaining their full health potential because of their social position or other socially determined circumstance. Reduction of disparities in clinical outcomes requires the prioritisation of high-impact solutions in under-resourced areas, involving tailored strategies for decentralised and integrated care, and support from global and regional partners to improve the availability of interventions for cardiovascular disease prevention and management. Front-line health workers with shared competences for cardio–obstetric care, digital health, and portable ultrasound should be used to deliver decentralised care, improve referral systems, and support surveillance of sex-related outcomes. Digital health provides opportunities to enhance the quality, efficiency, and safety of primary health care, as well as help address racial and ethnic disparities,14 but insufficient digital health competencies among front-line health workers are among the factors that hamper the adoption of digital tools and technologies.15 Finally, as emphasised in the Commission, peer-to-peer supporters and educators in local communities should be used to empower women in improving their ability to access, understand, appraise, and apply health information to promote good cardiovascular health.
In the midst of the COVID-19 pandemic, values of human dignity, solidarity, altruism, and social justice should guide our communities to ensure equitable share of wealth and leveraging of efforts towards the reduction of cardiovascular disease burden in women worldwide. The Commission's recommendations on additional funding for women's cardiovascular health programmes, prioritisation of integrated care programmes, including combined cardiac and obstetric care, and strengthening of the health systems accords with efforts to bridge the gap for the world's worst off.5 Such a shift in women's cardiovascular care would be a major step towards equity, social justice, and sustainable development.
