Machine Learning in Cardio-Oncology: Innovation or Overhype?
摘要
Cancer therapies significantly increase cardiovascular disease risk, with cancer patients facing up to 42% higher likelihood of developing cardiovascular complications compared to those without cancer. This review examines current applications of artificial intelligence (AI) in cardio-oncology, focusing on pre-treatment risk prediction, detection of cardiovascular dysfunction during and after therapy, and clinical implementation challenges.
Recent FindingsAI applications have shown promising results across multiple domains. Machine learning models integrating electronic health records, ECG data, echocardiographic findings, and advanced imaging have demonstrated feasibility in identifying high-risk patients before treatment initiation. For detecting cardiac dysfunction, AI-enhanced tools have shown superior performance in identifying subtle cardiotoxic effects, including AI-ECG and- imaging models detecting reduced ejection fraction with high accuracy, automated strain analysis for early dysfunction detection, and AI-guided handheld ultrasound enabling point-of-care monitoring by non-specialists. Despite these advances, significant barriers prevent clinical implementation, including limited high-quality datasets representing diverse oncology populations, lack of standardized outcome definitions, model interpretability challenges with “black box” systems, and insufficient integration with existing clinical workflows.
SummaryWhile AI demonstrates substantial potential for improving outcomes through enhanced risk stratification and early detection, current evidence does not yet support widespread implementation. Success will require rigorous prospective validation, improved interpretability, and comprehensive implementation strategies addressing both technical and human factors.
