Combining Traditional Statistical Methods with Explainable Machine Learning for Assessing Recurrence Risk of Atrial Fibrillation Following Pulsed Field Ablation: A Hypothesis-Generating Study from a Single Center
To evaluate the predictive value of preoperative NT-proBNP for AF recurrence post-PFA and identify clinically relevant risk thresholds using an explainable machine learning framework, emphasizing its role in enhancing predictive accuracy.
Key Findings:
Preoperative NT-proBNP levels may serve as a sensitive predictor for AF recurrence post-PFA, suggesting a shift in clinical practice.
Traditional risk scores may not be applicable in the contemporary PFA population due to a ceiling effect.
Explainable machine learning methods can identify feature interactions and risk thresholds relevant to AF recurrence.
Interpretation:
The study suggests that NT-proBNP could enhance risk stratification for AF recurrence after PFA, highlighting the need for technology-specific predictive tools to improve patient outcomes.
Limitations:
Small sample size (n = 92) and limited events (n = 13) may affect the robustness of findings.
The study is retrospective and conducted at a single center, limiting generalizability and introducing potential biases.
Conclusion:
This exploratory study indicates the potential of integrating NT-proBNP and explainable machine learning in predicting AF recurrence post-PFA, warranting further prospective validation.
