A roadmap of strategies to support cardiovascular researchers: from policy to practice


Cardiovascular disease remains the leading cause of death worldwide. Cardiovascular research has therefore never been more crucial. Cardiovascular researchers must be provided with a research environment that enables them to perform at their highest level, maximizing their opportunities to work effectively with key stakeholders to address this global issue. At present, cardiovascular researchers face a range of challenges and barriers, including a decline in funding, job insecurity and a lack of diversity at senior leadership levels. Indeed, many cardiovascular researchers, particularly women, have considered leaving the sector, highlighting a crucial need to develop strategies to support and retain researchers working in the cardiovascular field. In this Roadmap article, we present solutions to problems relevant to cardiovascular researchers worldwide that are broadly classified across three key areas: capacity building, research funding and fostering diversity and equity. This Roadmap provides opportunities for research institutions, as well as governments and funding bodies, to implement changes from policy to practice, to address the most important factors restricting the career progression of cardiovascular researchers.

Key points

  • Diversity is key to innovation, but the current system and culture of the cardiovascular research sector are driving researchers, particularly those from under-represented groups, out of the sector.

  • Our team conducted research to identify the key short-term, medium-term and long-term solutions to addressing issues faced by early-career and mid-career researchers, focusing on three key areas: capacity building, research funding and fostering diversity and equity.

  • Capacity building needs to support collaboration and team-based research, improve and incentivize mentorship, and provide training to cardiovascular researchers to develop management, financial and communication skills.

  • Research funding needs to be used to improve job security and the assessment of career disruptions and opportunities and to support early-career and mid-career cardiovascular researchers to prepare for leadership roles.

  • To improve diversity and equity in cardiovascular research, working parents, women and individuals from other under-represented groups need additional support.


At present, cardiovascular disease (CVD) remains the main cause of morbidity and death worldwide1. In addition to new therapies, cost-effective policies and practices are urgently needed to prevent avoidable deaths from CVD. Research has shown that diversity in the workforce — which refers to involvement of individuals across the spectrum of gender, race or ethnicity, disability status, nationality, religious affiliation, sexual orientation and socioeconomic background in the workplace — drives innovation and performance2. Therefore, a diverse and stable cardiovascular research workforce is essential to identify solutions to tackle the global CVD burden. This diversity is particularly important to ensure that the solutions identified address the issues faced by the vast majority of the population, particularly those who are currently under-served by the existing health-care system3,4.

Some progress has been made in the past decade in improving diversity and equity in the sector, with several countries implementing national programmes to address these issues in research and academia. However, some evidence suggests that the cardiovascular research workforce is at imminent risk from low staff retention. In a 2019 survey involving >500 cardiovascular researchers in Australia, two-thirds of the participants had considered leaving the cardiovascular research sector or did not feel that they had long-term career prospects in cardiovascular research owing to the lack of long-term job security and funding5. Worryingly, these and other issues were twice as prevalent in women than in men5. Indirect evidence from other countries demonstrates that Australian cardiovascular researchers are not alone6,7,8. Although these concerns might reflect a broader issue affecting the biomedical research sector as a whole, such issues seem to be exacerbated in the cardiovascular research field owing to insufficient funding for cardiovascular research and development in the USA and Europe6,7, particularly for discovery research8. Moreover, a shortage in the cardiology workforce has remained for nearly two decades9, and women continue to be under-represented among cardiologists10. On the basis of this information and data from other areas of research11,12, these workforce challenges are likely to be occurring elsewhere in the world. Such challenges have been exacerbated by the coronavirus disease 2019 (COVID-19) pandemic, with evidence that the pandemic is worsening the gender and race or ethnicity disparities among researchers13,14 and is driving an overall phenomenon called ‘the great resignation’, particularly among mid-career employees15. Consequently, solutions to stop the ‘brain drain’ of cardiovascular researchers and to improve retention and increase diversity are immediately needed.

To address this issue and identify potential solutions, focus groups involving 34 Australia-based early-career and mid-career researchers (EMCRs) working in cardiovascular research were formed in 2021 (ref.16). These researchers were involved in different fields of cardiovascular research and represented different ethnicities, genders and LGBTIQA+ (lesbian, gay, bisexual, transgender, gender diverse, intersex, queer, asexual or questioning) identities, as well as differing levels of caregiving responsibilities. These focus groups resulted in 92 proposed solutions across three key areas: capacity building, research funding, and fostering of diversity and equity17 (Table 1). By undertaking a review of the international literature, we have extended these solutions with practical examples from the global community. In this Roadmap article, we present short-term, medium-term and long-term strategies that could be implemented at an individual, organizational and sector level, from policy to practice, to support the careers of cardiovascular researchers worldwide (Fig. 1).

The figure provides a summary of the current reality and the future changes needed to support early-career and mid-career researchers (EMCRs) in the cardiovascular sector, with a focus on individuals from under-represented groups, including women and individuals from ethnic and other minorities.

Roadmap for capacity building

Reducing the burden of CVD globally in the short-term (<1 year), medium-term (1–5 years) and long-term (>5 years) requires a strong and secure pipeline of biomedical, clinical and public health researchers. Therefore, targeted investment in the career development of EMCRs is key to capacity building. In this section, we highlight strategies for building capacity with a specific focus on supporting collaborations, mentorship and training. Although the resources available to support and improve the career development of EMCRs might differ between low-income, middle-income and high-income countries16,18, many of the strategies suggested can be implemented without cost or are low cost and can be facilitated through local and international networks and societies.

Support multidisciplinary collaborations

Short-term strategies

EMCRs could be supported to organize and attend regular meetings where clinical, biomedical and public health researchers can interact and share ideas. This approach would inform the direction of research and might lead to new research interests and collaborative projects. EMCRs could promote their research interests and skillset and identify potential collaborations through online platforms that allow cardiovascular researchers to connect and share ideas. For example, the Trainee Advocacy Committee of the American Heart Association (AHA) Council on Hypertension comprises EMCRs who contribute to all aspects of the organization of their annual scientific meeting, allowing them the opportunity to collaborate with researchers across different cardiovascular fields and levels of seniority19. Another example is the Global Cardiovascular Research Funders Forum, founded by 11 cardiovascular research bodies from Australia, Canada, Europe, New Zealand and the USA20. The forum aims to accelerate the pace of research progress by creating opportunities for cross-border coordination and collaboration between world-leading cardiovascular researchers and organizations to advance the prevention, diagnosis and treatment of CVD. Similar forums could be conducted at national and international levels through professional societies and organizations and could operate on an opt-in basis for EMCRs.

Medium-term strategies

EMCR-specific seed funding is invaluable in establishing job independence and collaborative research. Existing funding schemes could be redesigned to promote cross-disciplinary collaborations, support EMCR-only or EMCR-majority teams, encourage clinician–scientist collaborations, and stipulate mandatory inclusion of an EMCR as part of the principal investigator team or even as a co-lead investigator. Although some grant schemes focus on funding EMCRs, such as the NIH Pathway to Independence Award (K99/R00) programme21 and the European Research Council starting grants (for early-career researchers) and consolidator grants (for mid-career researchers), these funding schemes target only individual researchers, rather than promote collaborations or team-based research. An innovative training programme called MINDSHIFT, funded by the European Commission for the years 2021–2026, aims to promote an interdisciplinary research programme across Europe to bridge knowledge gaps in hypertension research. This funding model could be adapted elsewhere in the world to improve collaborative efforts. Another important aspect of cardiovascular research is engagement with patients, who are experts by experience and can improve the relevance and applicability of research22,23. Facilitating connections between patients and EMCRs would increase awareness about the barriers faced by patients and their families, and cardiovascular researchers, and improve study design and effectiveness.

Long-term strategies

The development of infrastructure that facilitates the co-location of clinicians and non-clinician biomedical researchers might promote further cross-pollination of research interests and perspectives (Box 1). Capacity-building efforts should include collaboration between researchers at all levels of seniority, funding bodies and stakeholders (patients, programme organizers and policymakers) at the local, state, national and international levels18. The changes needed to reduce the burden of CVD require sustained awareness and advocacy among all stakeholders24. One example of an effective and broad collaborative effort is the regional cardiovascular research networks across Australia, such as the New South Wales Cardiovascular Research Network (Box 2). Moreover, the stagnation of cardiovascular drug development over the past two decades is a well-known issue25, which could be at least partially addressed by stronger partnerships between academia and industry. Such collaborations have already been established in other fields in the UK26, with Novo Nordisk investing up to £115 million in a new research centre at the University of Oxford for the development of innovative approaches to the treatment of type 2 diabetes mellitus27, and AstraZeneca locating one of its global research and development centres at the University of Cambridge28. In addition, India has approved its first industry–academia partnership programme (the Biopharma Mission) to accelerate discovery research and facilitate the development of products, including vaccines and medical devices29. The Biopharma Mission aims to improve technology transfer capabilities in the public and private sectors and to support start-up companies and small-sized and medium-sized enterprises to build the capacity for sharing innovative research29. Similar partnerships in the cardiovascular research sector would generate new opportunities for EMCRs, including more industry-funded fellowships.

Incentivize mentorship and sponsorship

Effective mentorship is a key factor in the development, success and retention of EMCRs in research settings30,31. At present, more investment in mentorship and sponsorship is needed to support career advancement for women and other under-represented groups32,33. Academic sponsors who advocate for the career development of EMCRs are crucial, particularly to bridge the equity gap by increasing the number of cardiovascular researchers from under-represented groups to be promoted to senior leadership positions33,34.

Short-term strategies

Cardiovascular institutions, networks and societies could establish small peer-mentoring groups made up of EMCRs who can provide support for each other. Importantly, all EMCRs should be encouraged to join mentoring programmes at institutional, national and international levels, such as the AHA Mentoring for Professionals35 scheme and the International Society of Hypertension (ISH) Mentorship programme36. The MINDSHIFT programme also partners researchers with at least two independent research institutions across Europe to increase mentoring opportunities. Moreover, cross-sector mentoring programmes can provide opportunities to facilitate translation of basic science research to the clinic. For example, the Australian Cardiovascular Alliance offers a cross-sector mentoring programme that connects biomedical scientists, clinical researchers, health services and public health researchers, clinicians, policymakers and industry leaders37. EMCR mentees and mentors should undergo formal mentorship training to learn how to navigate and gain the most value from the mentor–mentee relationship. In particular, mentors should be provided with training to increase their awareness of diversity. At present, formal mentorship training programmes for academic researchers are scarce, particularly in low-income and middle-income countries (LMICs)31,38. A notable example is the Fogarty Global Health Program for Fellows and Scholars, which includes a mentorship workshop to train mid-level and senior-level investigators working in public health and clinical and basic science research across multiple academic institutions in LMICs31.

Medium-term strategies

To encourage involvement from supervisors and senior mentors, funding bodies could build mentorship requirements into grant applications, whereby senior applicants would be required to describe how they will build research capacity and mentor EMCRs within and, importantly, across research groups. Additionally, institutions could provide career coaching and secondment opportunities to develop and improve mentoring skills. Career coaching, as distinct from mentorship, is designed to help individuals to set and reach personal goals and is advantageous for career planning and leadership training.

Long-term strategies

Periodic evaluation of mentoring and sponsorship schemes is crucial to ensure that these programmes are effective and are having a positive effect on the career development of cardiovascular researchers. Furthermore, a robust review of mentoring programmes encourages institutional leadership support and creates local ownership of the initiative29. In this regard, a six-point framework to review and evaluate mentorship programmes has been proposed, which encompasses aspects of the mentor–mentee relationship, career guidance, academic productivity, networking, wellness and organizational capacity39.

Provide training to improve professional skills

Early in their career, EMCRs are trained to become good scientists who are proficient at collecting, analysing and discussing their research. As EMCRs transition from postdoctoral fellows to independent research leaders, they are suddenly faced with a myriad of new challenges with little-to-no formal training. These new challenges can include recruitment and management of staff, finance administration, science communication and the balancing of clinical or teaching loads with research, while simultaneously trying to build their research programmes and secure research funding to establish themselves as leaders in their respective fields. Indeed, results from a survey of 3,200 scientists revealed that two-thirds of laboratory heads had not received any training on the managing and mentoring of staff and students40. The training and development of EMCRs, in both a research and a professional capacity, are crucial to provide a strong foundation on which to build an independent and sustainable research career in cardiovascular research.

Short-term strategies

Areas of training for EMCRs could include communication, leadership, and financial and project management. Such training programmes can improve general skills and are helpful in building a people-centred research culture. Training programmes should also extend beyond intra-institutional and inter-institutional opportunities to include local, regional and national agencies. For example, a training initiative for early-career researchers from LMICs that was developed by the National Heart, Lung, and Blood Institute–UnitedHealth Collaborating Centers of Excellence includes training in project management21,41,42. In addition, the World Heart Federation Salim Yusuf Emerging Leaders Programme provides professional development and mentoring opportunities alongside research capacity building activities43. However, these programmes are usually extremely competitive, with only a small number of researchers who can participate. Advocacy and support of these training programmes for a wider range of EMCRs are vital and should be prioritized by institutions to ensure they remain sustainable. Many societies and organizations offer training webinars involving established researchers who share their experience. The design of such sessions to have a clear learning outcome focused on professional development would provide accessible training that is currently not widely available to cardiovascular researchers.

Medium-term strategies

Institutions should consider offering specific training to early-career researchers to support their transition from a PhD graduate to a postdoctoral scientist, and from postdoctoral to leadership positions. The responsibilities of postdoctoral fellows differ between countries, but commonly include tasks such as finance management, grant administration and staff recruitment, which are often expected of these researchers without provision of additional training. Institutions should also be encouraged to integrate professional skills training into Masters and PhD programmes to fully equip graduates with the skillset required as they transition into their next academic or non-academic role, or as part of an on-boarding programme during postdoctoral training.

Long-term strategies

Instituting training of professional skills across the short-term and medium-term, as described above, should help to build leadership capacity in EMCRs. This training should be made compulsory as part of the promotion process, so that future leaders are well equipped with the skills necessary to succeed in cardiovascular research and beyond. Of note, professional development and leadership training programmes must be well designed and have the backing of a strong and supportive institutional culture44. Therefore, the training should optimally be delivered by external parties or collaboratively between broad stakeholders and designed to suit local research environments.

Roadmap for research funding

The cardiovascular research sector is seeing lower success rates for competitive funding schemes than in previous decades, with overall less funding available for cardiovascular research and development6,7,8. Moreover, the average age of awardees is increasing. For example, in the USA, the average age at which a scientist secured their first NIH R01 grant increased from 40 years in 1995 to 44 years in 2020 (ref.45). The distribution of NIH funding support is also highly skewed, with 10% of NIH-funded researchers receiving 40% of the total funding available45. This finding is particularly relevant given the reports suggesting that innovative research is driven by EMCRs46, who are disproportionately affected by lack of funding owing, in part, to biases against junior scientists46. To address these longstanding issues, the NIH launched an EMCR-specific biomedical scheme, the Next Generation Researchers Initiative45. Considering that cardiovascular research has one of the highest cost–benefit ratios of all biomedical research fields (Australian $9.8 return for every dollar invested in Australia47 and a 20.6% internal rate of return in Canada48), investing in funding that specifically benefits cardiovascular EMCRs should be an obvious choice. In this section, we discuss the major barriers faced by cardiovascular EMCRs in securing competitive funding and how these challenges can be overcome. An example of a well-designed and well-implemented funding scheme is described in Box 2.

Increase job security

Many outstanding researchers with strong track records and notable contributions to health and medical research are appointed on short-term (6-month to 18-month) contracts5. This situation has evolved owing to many complex, interrelated factors, such as short-term research funding, and will not be improved quickly or without strong leadership and advocacy, underscoring the societal and economic cost of the lack of support for cardiovascular research to address our CVD burden.

Short-term strategies

EMCRs should be provided with access to objective and critical career development advice to increase awareness of different career pathways, including industry roles and entrepreneurship.

Medium-term strategies

Mid-career researchers have a specific set of career challenges; they are expected to compete with established senior researchers for grant funding, while having a large administrative burden as they try to maintain research independence and acquire international recognition49. In this regard, funding schemes have been developed to specifically cater to mid-career researchers, such as the NIH Next Generation Researchers Initiative45 and the European Research Council consolidator grant. The development of strong connections and formal collaborations with industry and policymakers is essential for the continuity of the cardiovascular research pipeline, including opportunities to develop co-funded, longer-term postdoctoral roles between research institutions, industry and the government. Such conjoint roles are essential in improving management and policy and to shift biomedical discoveries along the translational pipeline. In addition, little support exists for a team-based approach to research for mid-career researchers who are willing to contribute to a research programme, but are not necessarily ready to lead a research team. Grant schemes could be improved by better recognizing the team-based approach that is required to conduct high-quality research, rather than recognizing only an individual lead investigator.

Long-term strategies

Funding agencies can contribute to improving job security for researchers by requiring research institutions to set a minimum duration of employment contracts for research staff. Employers of grant recipients should also be contractually obliged to ensure that a predefined number of staff employed through the grant are provided with an employment contract that aligns with or extends beyond the term of the grant. Longer-term goals such as an extension in the research project, dissemination of results, applications for the next stage of research funding and investment in the translation or implementation of findings are all contingent on the researcher’s job security. Moreover, creating long-term research opportunities for professional researchers who provide essential training and increase the overall capacity of institutions would allow further employment opportunities while retaining expertise. For example, in France, a tenured research position with INSERM (the National Institute of Health and Medical Research) is possible by way of a nationally competitive examination. A nationally relevant set of expectations or minimum standards to secure ongoing employment would dramatically shift the research culture towards innovation that comes with job security. Finally, in a post-COVID-19 world, with new and re-imagined workplace practices and a greater understanding of career opportunities and disruptions, researchers who want to work part-time should be treated equitably with regard to expectations on output and workload compared with those in equivalent full-time positions.

Improve assessment of career opportunity

Australia’s major medical research funding body, the National Health and Medical Research Council (NHMRC), introduced the policy ‘relative to opportunity’ in recognition of the fact that over a given period of time, researchers might not have equitable opportunities to advance their career. This term is used to acknowledge that career breaks, carer responsibilities, stage of career, time dedicated to research and access to resources can all have an effect on scientific track record and productivity. Therefore, consideration of a researcher’s achievements relative to opportunity should take into account the differences in career progression and opportunity owing to differences in life circumstances. However, no formal infrastructure exists to guide peer-reviewers in the assessment of achievements that are relative to opportunity within funding applications. The solutions below describe how such a relative-to-opportunity policy could be fairly implemented and assessed, offering valuable guidance for other countries.

Short-term strategies

Peer-reviewers, promotion panels and institution leaders involved in the grant review process should receive training on how to assess the effect of relative opportunity and other factors contributing to scientific track record; this training needs to be developed, implemented and legislated. Just as a Good Clinical Practice certification is required to conduct clinical research, or a higher degree in research supervision training is required before being able to oversee doctoral students, grant reviewer training or certification should become compulsory for peer-reviewers involved in the assessment of funding applications and for all institutional leaders. National and international research organizations should provide leadership to develop and implement consistent cross-sector training and certification programmes, providing one course that is relevant to all funding bodies in the country.

Medium-term strategies

Relative-to-opportunity considerations should involve a formalized, documented and standardized process during the application for grants, employment, promotion or leadership opportunities that are offered by research institutions and funding agencies. For applicants, this process could include mention of career disruptions and other factors affecting relative opportunity. At the peer-review stage, a standardized protocol should be developed to acknowledge that relative-to-opportunity considerations have been examined and considered for each applicant.

Longer-term strategies

Relative-to-opportunity considerations can be quantified by quartiles or tertiles on the basis of full-time-equivalent research time, with peer-review scores weighted accordingly. The allocation of additional funding to support near-miss funding applications from researchers who have experienced substantial career disruption and relative-to-opportunity barriers might also address existing inequalities in funding distribution.

EMCR leadership opportunities

Leadership in the research sector can be formal (such as on committees and boards or in institutional leadership positions) or less formal (as in grant and manuscript preparation in team and group roles). In this section, we describe how current cardiovascular research leaders can create opportunities for future leaders.

Short-term strategies

Access to opportunities for leadership roles are often reliant on supportive senior researchers and personal factors such as confidence, skills and capacity. However, many EMCRs struggle during the transition to a lead investigator role50. Measurable performance expectations need to be established to enable senior leaders to provide opportunities for the next generation of cardiovascular research leaders, such as co-supervision of students and a co-leadership role in preparing research grants or papers, with proper acknowledgement of the contribution by the EMCR (such as co-senior or co-corresponding authorship). These achievements have only a marginal value for the track record of senior leaders, but have an enormous effect on the career development of EMCRs.

Medium-term strategies

Given the fiscal pressures on research funding, grants should be scaled to ensure EMCRs are encouraged and supported to be named as principal investigators or co-principal investigators in research projects. Indeed, funding agencies need policies that specify mandatory inclusion of EMCRs in grants.

Long-term strategies

Any instances of senior research leaders promoting EMCRs to research leadership positions, primarily through research funding opportunities, should be formally acknowledged through prestigious awards for research mentoring, such as those from the ISH51. Moreover, we propose that mentorship of more junior staff, particularly EMCRs, should be included as key performance indicators in annual and promotion reviews of senior cardiovascular researchers.

Diversify funding evaluation

Many high-income countries such as France52, Germany53 and the USA54 have announced boosts to their research budget in the next 5–10 years. However, research funding continues to be limited in most regions of the world, particularly for the cardiovascular sector6,7,8, and remains a major reason why cardiovascular researchers leave the sector5. Therefore, ensuring fair distribution of funding is crucial for retention of expertise.

Short-term strategies

To minimize the effect of unconscious bias and ensure alignment with funding priorities, peer-review panels need to be gender-balanced and include patients and carers, and industry-based experts, as well as researchers from different disciplines and ethnicities, career stage and backgrounds (including those from under-represented groups, such as indigenous persons, and culturally and linguistically diverse individuals). In addition, where possible, applications should be de-identified to reduce bias.

Medium-term strategies

Ideas-based funding, whereby the applicant’s track record is peer-reviewed only to assess feasibility and not to rank applications, might help to overcome some of the biases experienced by women and individuals from other under-represented groups. Moreover, the outcomes of these funding schemes should be carefully reviewed to ensure they result in knowledge gain and are indeed distributed equitably. The NHMRC in Australia found that although the percentages of men and women awarded ideas-based funding in 2019–2021 were similar, female principal investigators received a total of Australian $44 million less per year than male counterparts55. Data on other under-represented groups or specific to the cardiovascular field are not available. With success rates in funding schemes as low as 5–15% in many instances (for the years 2019–2021), careful review of the value proposition to researchers of applying for several grants throughout the year needs to be considered. Streamlining the grant process and consolidating funding requirements across different funding schemes will improve efficiency. For example, shorter preliminary applications that are peer-reviewed, in which only a proportion (30–50%) of candidates are invited to submit a full application, might also improve efficiency. Furthermore, by staggering funding rounds throughout the year and restricting eligibility to those who have not already received funding in that year will result in more equitable distribution of research funding (Box 2).

Longer-term strategies

Although national research priorities are often mentioned in calls for research funding applications, to what extent funding is awarded on the basis of alignment with research priorities, disease burden, contribution to health outcomes or delivery of care is unclear. For example, a 2021 international analysis of support for nursing and allied health research indicates that in the UK, nurses, midwives and allied health professionals account for more than two-thirds of the health-care workforce, yet only 1%, <1% and 4% of trainees from these professions, respectively, are supported by the National Institute of Health Research56. Similarly, in Australia, only 0.4% of NHMRC fellowships in 2020 were awarded to midwifery, 3% to nursing and 7% to allied health departments, despite these professions representing 80% of the registered health practitioner workforce56. Lottery-style funding programmes, especially for ideas-based grants, might be appropriate in settings with limited research funding to target applications that are deemed by peer-review to be worthy of funding, despite failure to secure funding. This approach has been adopted by the Health Research Council of New Zealand57. Although perhaps a controversial idea, if all research proposals and their feasibility are peer-reviewed and deemed fundable or not fundable, all those deemed fundable should have an equal chance of being funded, irrespective of other factors that might bias the ranking of funding applications. After a trial period, the outcomes of these funding schemes should be assessed to determine whether they deliver value, lead to knowledge gain and are distributed equitably.

Roadmap for diversity and equity

Equity is the acknowledgement that individuals with diverse circumstances require specific resources and opportunities to reach an equal outcome58. Growing evidence indicates that more diverse and equitable workplaces will achieve greater innovation, discovery and benefit3,59. Notably, historically excluded and marginalized groups continue to be under-represented and under-supported in cardiovascular research. Despite calls for change, the research sector still lacks leadership, policies and strategies to provide equitable access to opportunities. Cardiology is a male-dominated profession, and cardiovascular research, like many areas of academia, has disproportionately fewer women and individuals in ethnic minority groups in training fellowships, clinical roles and leadership positions60,61,62,63. Women are also under-represented in leadership roles, such as membership in cardiovascular guideline-writing committees64 and cardiovascular clinical trial leadership committees65. Therefore, solutions to meaningfully tackle and reduce inequity and improve diversity are urgently needed. Some national programmes have been specifically designed to address this issue (Box 3), but the benefits imparted by these programmes remain to be seen. In this section, we present possible strategies and solutions to support diversity, equity and inclusivity in the cardiovascular research sector (Table 2).

Table 2 Domains of action to promote DEI in cardiovascular research

Support primary caregivers

Short-term strategies

Primary caregivers, both male and female, should be supported to maintain research engagement during parental and carer’s leave, upon return to work and for the long-term. Workplace policies should consider whether the timing of meetings and conferences is suitable for parents and carers and should optimally provide targeted support for parents and carers, such as financial support for childcare or an option of virtual meeting attendance. Practical support is required to allow the continuation of work during periods of leave, such as funds to employ a research assistant17,66. Parental leave, in particular, is a crucial period of high researcher attrition, with a survey of researchers in the USA revealing that 43% of new mothers and 23% of new fathers who were employed full-time before having children either did not return to academia or returned part-time after having children67.

Medium-term strategies

To support the transition of parents and carers back to the workforce, flexibility is required in the duration of the secured grant funding period to allow for the time absent from research, as well as in allowing researchers to work part-time. Workplaces that provide such flexibility are more likely to retain employees with caregiving responsibilities68.

Long-term strategies

To shift the status quo, greater incentives are required to encourage more equitable sharing of parental leave, such as gender-neutral leave policies that encourage leave arrangements to be split between carers. Importantly, creating policies that increase opportunities for both men and women to combine paid employment with unpaid caring responsibilities can help to recalibrate gender roles69. Organizations that provide strong parental leave schemes have greater recruitment and retention of staff70. Sweden has been a long-standing leader in such progressive parental leave policies71. Further to these changes, an acknowledgement of the effect of carer responsibilities on career disruptions during grant funding reviews is also important.

Support women

Short-term strategies

Increasing the visibility of women and celebrating their research accomplishments are key in demonstrating to female EMCRs the possibility of a successful career as a female cardiovascular researcher. The Organization for Women in Science for the Developing World aims to increase the participation, opportunities for collaboration and leadership skills of women from LMICs72. Furthermore, the Future Professors Programme in South Africa focuses on supporting Black and female researchers to achieve professorial level by providing mentorship and skills training and fostering collaborative efforts73. Women-focused and structured mentoring programmes, such as those led by Franklin Women in Australia74, have been shown to improve the participants’ knowledge, skills and research metrics required for promotion. The framework of such initiatives could be implemented by cardiovascular research societies globally.

Medium-term strategies

Grant and publication review processes need to be re-evaluated to minimize unconscious reviewer bias, such as by removing identifiable information from the applicants and authors (such as gender and region of origin) and through the use of gender-neutral language17. To extend this goal further, grant committees should aim to fund male-led and female-led projects equally and ensure that gender-specific data on grant success are collected and reported publicly. The South African government has developed projects, such as the Black Academics Advancement Programme75, to prioritize women and other under-represented groups in funding applications, resulting in the greater success of female-led initiatives across all career stages.

Long-term strategies

To unpick long-standing gender biases, group coaching and reverse mentoring (that is, when a female EMCR mentors a senior leader on the issues that EMCRs face)76 are required to increase awareness of gender bias. Moreover, a study has shown that female faculty dedicate more time to service (such as service to the university, campus, or local and international communities) than male faculty77. Therefore, strategies should be in place to ensure service and social roles are distributed evenly across genders.

Support under-represented groups

Short-term strategies

In response to continued issues of racism in society, many institutions have mandated diversity and bias awareness training for all staff and students. Importantly, these training modules should not be undertaken as a one-off exercise, because evidence suggests that such modules result in limited behaviour change78. Therefore, training should be carefully designed and, if possible, undertaken at regular intervals, with outcomes assessed79. Scientific societies could also increase visibility of under-represented researchers, such as the Black in Cardio campaign, which celebrates exceptional Black cardiovascular researchers80, and Black in Physiology, which is associated with the American Physiological Society.

Medium-term strategies

To address barriers to career progression and workplace participation for researchers from under-represented groups, grant schemes that fund discretionary items such as parental or carer support, visa fees or conference registration should be considered. Financial barriers associated with opportunities that are advantageous for career progression are often a limiting factor for those from low socioeconomic backgrounds and single-income households, as well as those with carer’s responsibilities.

Long-term strategies

Research produced by more ethnically diverse teams has been shown to have increased value compared with that from less ethnically diverse teams59. Given the globally connected nature of research, national funding bodies should consider funding schemes to attract and retain international talent. In Australia, most nationally competitive funding schemes will fund permanent residents or citizens, but not individuals on temporary work visas17. In addition, strategic partnerships with international institutions need to be carefully considered and developed to build capacity between and within high-income and low-income countries. Lastly, individuals with disabilities should be provided with a safe and accessible workplace.


We acknowledge that several of the issues highlighted in this Roadmap article are not exclusive to the cardiovascular research sector. However, considering the reduced funding investment into cardiovascular research globally, these issues might be of increased relevance in this sector. The solutions proposed in this Roadmap article were identified by cardiovascular researchers from diverse backgrounds. Of note, however, these solutions originated in Australia and might not necessarily reflect the needs and views of cardiovascular researchers in LMICs and in some under-represented groups. To broaden the relevance of the solutions that we have proposed, we engaged with eight cardiovascular researchers who are a part of institutions in nine countries (see Acknowledgements). The researchers from high-income countries (Canada, Italy, New Zealand, the UK and the USA) agreed that our proposed roadmap accurately presents the major issues faced by EMCRs in their regions. Overall, those from LMICs (Brazil, India and South Africa) commented that although cardiovascular researchers from LMICs would benefit from the solutions proposed, these researchers also face other major issues specific to the region. In particular, they mention that inadequate research funding in their region limits conference participation and research publication and therefore does not support a sustainable research culture81. This issue might be addressed by increased international investment into local infrastructure and resources (such as local biobanks) and more international collaborations. Strategic and immediate solutions to support the inclusion of cardiovascular researchers from LMICs include free membership to professional societies, waived fees for online conferences and publications, training grants for doctoral and postdoctoral researchers, local mentoring programmes, and inclusion on editorial boards of journals and committees of professional societies. Given that LMICs are disproportionately affected by CVD2, inclusion of researchers from these regions in global research is key to reducing the global burden of CVD.


A diverse and collaborative cardiovascular research workforce is crucial to finding solutions to reduce the global burden of CVD. However, the current culture of cardiovascular research is not supportive of diversity and collaboration and often inhibits the career progression of EMCRs. These factors, together with the global downward trend in available funding for cardiovascular research, are driving researchers out of the sector. Immediate action needs to be taken to prevent the loss of an entire generation of cardiovascular researchers, particularly those from under-represented groups. The effect of this loss on the burden of CVD in the future will be substantial, after well-established research leaders retire without a strong and secure pipeline of EMCRs and succession planning. The proposed roadmap of changes in this article could improve the cardiovascular research culture and support EMCR career progression, allowing the cardiovascular research sector to thrive and, in turn, to reduce the burden of CVD globally.
