Enterprise AI Analysis: Application of Artificial Intelligence in Predicting Open-Heart Surgery Outcomes
Application of artificial intelligence in predicting the results of open-heart surgery: a scoping review
This scoping review synthesizes research on AI in predicting open-heart surgery outcomes, evaluating AI model performance, and identifying gaps. It highlights the potential for personalized surgical planning, but notes limitations in data quality, algorithmic bias, and clinical applicability. The review identified 64 studies, primarily retrospective, with logistic regression, random forest, and XGBoost as the most common algorithms. XGBoost showed the best performance in 11 studies. Deep learning and hybrid models were underutilized. Key limitations include inconsistent model validation, limited prospective data, and lack of diversity in patient populations, hindering clinical translation.

Dominance of Retrospective Studies
The review highlights an overwhelming reliance on retrospective study designs (89.06%) in AI applications for open-heart surgery. While this approach is common due to data accessibility, it raises concerns regarding potential biases and limits the generalizability of findings. Future research needs to prioritize prospective designs and external validation to enhance clinical utility and mitigate biases, developing design standards for AI implementation.

XGBoost as Top Performer
XGBoost emerged as the most consistently high-performing algorithm, achieving the best performance in 34.4% of the studies (11 out of 32 studies where it was used). Its robustness in handling complex, non-linear relationships, sparsity, missing data, and class imbalance (e.g., rare events like mortality) makes it highly suitable for surgical datasets. This outperforms simpler models like Logistic Regression and even deep learning on smaller, heterogeneous tabular datasets.

Underutilization of Deep Learning and Hybrid Models
Despite their potential, deep learning and hybrid models are significantly underutilized in cardiac surgery AI. This is attributed to challenges like opacity in model outputs, substantial training resource demands, large high-quality dataset requirements, and the 'black box' nature that erodes clinician trust. Future work should focus on standardized frameworks for validation, improving explainability, and fostering collaboration between clinicians and data scientists.

Real-world Impact: AKI Prediction
XGBoost-based models, identified as top performers, are directly influencing clinical decision-making by predicting acute kidney injury (AKI) post-cardiac surgery. These models enable early identification of high-risk patients, guiding clinicians to implement preventive interventions such as optimized perioperative fluid management and nephrotoxic agent avoidance, thereby supporting proactive patient management and improving outcomes.
Predicting Acute Kidney Injury (AKI) with XGBoost
One of the most impactful applications of AI in open-heart surgery, as identified by the review, is the use of XGBoost models for predicting acute kidney injury (AKI) post-surgery. These models, which demonstrated best performance in 11 studies, allow for the early identification of high-risk patients. This proactive insight enables clinicians to tailor interventions, such as adjusting fluid management strategies, avoiding nephrotoxic agents, and enhancing postoperative monitoring. The direct clinical utility of these AI tools supports personalized surgical planning and significantly contributes to improving patient outcomes by preventing severe complications.
