Utilization of machine learning techniques to forecast episodes of heat-sensitive angina (HSA): findings from a multicenter observational cohort study
Clinical Report: Utilization of machine learning techniques to forecast episodes of heat-sensitive angina
Overview
This multicenter observational cohort study developed a random forest model to predict heat-sensitive angina (HSA) exacerbations using 14 identified risk factors. The model demonstrated strong predictive performance during both internal and external validation.
Background
Heat-sensitive angina (HSA) is a condition where patients with cardiovascular disease experience increased angina episodes in high-temperature environments. Understanding and predicting HSA is crucial for managing patients at risk, especially as climate change intensifies temperature extremes. This study addresses the gap in predictive tools specifically designed for HSA exacerbation under hot weather conditions.

Key Findings
14 predictors were identified as risk factors for HSA.
The random forest model showed strong predictive performance in both training and validation cohorts.
External validation confirmed the robustness of the random forest model.
Patients identified as high risk for HSA had increased angina frequency during summer months.
The model incorporates various clinical and serological markers related to inflammation and lipid metabolism.
Clinical Implications
Further prospective validation is necessary before routine clinical application.
Conclusion
The study presents a machine learning approach to predict heat-sensitive angina, requiring further validation.
