Synergistic Impact of Mental Health, Physical Health, and Sleep Duration on Heart Disease Prediction Using Ensemble Machine Learning Techniques

  • Abstract:
  • cardiovascular disease prediction models tradition- ally prioritize clinical biomarkers while underutilizing behavioral determinants. This study demonstrates that integrating mental health, physical health, and sleep duration with clinical data using a stacked ensemble machine learning framework signifi- cantly improves prediction accuracy. We engineer novel interac- tion features (BMI×MentalHealth, SleepTime×PhysicalHealth) to capture synergistic effects, validated through ablation studies. Evaluated on 113,284 patients, our model achieves 92.12% accuracy (ROC AUC: 0.9787) - a 7.12% improvement over clinical-only models (85.00% accuracy). The findings establish behavioral factors as non-redundant predictors, contributing 18.7% of predictive power (p < 0.001). This work advocates for integrating multidimensional health indicators into clinical decision support systems.
