# Diversity and Representation in Cardiovascular Research: Evidence Gaps, Emerging Models, and Policy Implications

## TL;DR

Cardiovascular research often excludes diverse populations, leading to biased guidelines and unequal health outcomes, so the paper proposes strategies to make research more inclusive and effective globally.

## Contribution

The paper reframes diversity in cardiovascular data as a scientific necessity and proposes a global roadmap for equitable research practices.

## Key findings

- Homogeneous datasets limit the validity of cardiovascular guidelines for women, ethnic minorities, and populations outside high-income countries.
- Structural under-representation in research leads to biased risk prediction and unequal health outcomes.
- Emerging strategies like data donation and inclusive biobanking can reshape cardiovascular research for equity.

## Abstract

Public health relevance—How does this work relate to a public health issue?
Cardiovascular disease guidelines are largely based on homogeneous datasets, limiting their validity for women, ethnic minorities, and populations outside HICs.Structural under-representation in cardiovascular research contributes directly to biased risk prediction, delayed diagnosis, and unequal health outcomes worldwide.

Public health implications—What are the key implications or messages for practitioners, policymakers and/or researchers in public health?
Researchers and regulators must embed diversity, data sovereignty, and community governance into study design, data infrastructures, and guideline development.Policymakers and clinicians should move from “one-size-fits-all” cardiovascular guidelines toward context-sensitive, population-aware risk models and prevention strategies.

Although cardiovascular disease (CVD) is the leading cause of mortality globally, it remains insufficiently understood in large parts of the world. The scientific foundations underpinning CVD risk prediction, diagnostics, and treatment are extensively derived from homogenous datasets, primarily including White, male participants from high-income countries. This lack of diversity and inclusion can lead to biased evidence, which in turn contributes to reduced diagnostic accuracy and the under-representation of key populations, and ultimately limits the generalizability of trial results and guidelines. In this paper, we discuss that diversity in cardiovascular data is a scientific necessity for valid and globally applicable knowledge and not just a matter of fairness. Drawing from emerging initiatives in genomics, digital health, and participatory research, we propose a global roadmap to reshape how cardiovascular research is conducted. This includes strategies such as data donation frameworks, inclusive biobanking, equitable AI development, and international policy change. Only by integrating diversity into scientific methodologies can we ensure that cardiovascular guidelines are effective, inclusive, and just.
