    Moderate data augmentation, particularly at 2×, significantly enhances the robustness of machine learning models for cardiovascular risk prediction.

  • 2

    Random forest achieved the highest accuracy of 94.0% and favorable sensitivity and specificity after applying 2× data augmentation.

  • 3

    SHAP and PDP analyses identified key factors influencing cardiovascular risk, including oldpeak, chest pain type, and maximum heart rate.

  • 4

    The study emphasizes the importance of interpretable and threshold-sensitive predictive tools for effective clinical decision-making.

  • 5

    Combining data augmentation with SHAP/PDP provides a methodological framework for deploying interpretable cardiovascular risk models.
