Abstract

AI algorithms can identify those at risk of cardiovascular disease (CVD), allowing for early intervention to change the trajectory of disease. However, AI bias can arise from any step in the development, validation, and evaluation of algorithms. Biased algorithms can perform poorly in historically marginalized groups, amplifying healthcare inequities on the basis of age, sex or gender, race or ethnicity, and socioeconomic status. In this perspective, we discuss the sources and consequences of AI bias in CVD prediction or detection. We present an AI health equity framework and review bias mitigation strategies that can be adopted during the AI lifecycle.

  • Even within the same geographic region, cardiovascular risk characteristics vary markedly across ethnic and healthcare subgroups.

    “Taken together, the evidence points to a central conclusion: even within the same geographic region, cardiovascular risk characteristics vary markedly across ethnic and healthcare subgroups.”

    From AI-driven cardiovascular risk prediction in patients with diabetes: bridging algorithmic innovation to equitable clinical application (2026) · cites this paper as [17]

    In “The role of AI in assessing risk, predicting, and detecting CVD” (page unavailable), the paper reports a disproportionate burden of CVD and cardiometabolic risk factors in some ethnic minorities and socioeconomically deprived groups. It does not establish that risk characteristics vary markedly within the same geographic region or across healthcare subgroups; its discussion of healthcare disparities does not make that specific comparison. (LLM, conf=0.82)

  • Assuming homogeneity across Asian populations or generalizing models developed from a single subgroup to the broader Asian population risks introducing systematic predictive bias and undermining equitable clinical utility.

    “Assuming homogeneity across Asian populations or generalizing models developed from a single subgroup to the broader Asian population risks introducing systematic predictive bias and undermining equitable clinical utility.”

    From AI-driven cardiovascular risk prediction in patients with diabetes: bridging algorithmic innovation to equitable clinical application (2026) · cites this paper as [17]

    The “Sources of AI bias” section (page unavailable) says that a training dataset that does not represent its target population can introduce bias, and that risk models may perform unequally across subpopulations. This supports the general warning about applying a model beyond the group in which it was developed, but the paper does not address homogeneity among Asian populations or generalization from one Asian subgroup to others. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Treating 'Asian populations' as a homogeneous entity-or extrapolating models developed in one Asian subgroup to all Asian individuals-can introduce systematic prediction bias.

    “Treating “Asian populations” as a homogeneous entity—or extrapolating models developed in one Asian subgroup to all Asian individuals—can introduce systematic prediction bias.”

    From AI-driven cardiovascular risk prediction in patients with diabetes: bridging algorithmic innovation to equitable clinical application (2026) · cites this paper as [17]

    The “Sources of AI bias” section (page unavailable) says models can perform unequally across subpopulations when training data do not represent the target population, supporting the general risk of prediction bias from extrapolation. It does not discuss Asian populations, differences among Asian subgroups, or models developed in one Asian subgroup and applied to others. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Bias can arise throughout problem formulation, dataset construction, model development, validation, and implementation in cardiovascular AI.

    “This is especially important because a recent scoping review found that fairness metrics are rarely reported in clinical risk prediction studies, while a recent cardiovascular AI perspective emphasized that bias can arise throughout problem formulation, dataset construction, model development, validation, and implementation (16, 17).”
  • Substantial heterogeneity exists even within Asian populations.

    “Furthermore, substantial heterogeneity exists even within Asian populations, adding another layer of complexity to risk prediction.”

    From AI-driven cardiovascular risk prediction in patients with diabetes: bridging algorithmic innovation to equitable clinical application (2026) · cites this paper as [17]

    The ‘Sources of AI bias’ and ‘How AI bias may limit CVD prediction and detection’ sections discuss differences in risk prediction across demographic groups, but do not address heterogeneity within Asian populations. Searches for ‘Asian’ and ‘heterogeneity within Asian subgroups’ found no passage supporting that specific claim; page numbers were not available in our copy. (LLM, conf=0.72)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
