Risk Prediction of Aortic Dissection Operation Based on Boosting Trees

Abstract

During the COVID-19 pandemic, the treatment of aortic dissection has faced additional challenges. The necessary medical resources are in serious shortage, and the preoperative waiting time has been significantly prolonged due to the requirement to test for COVID-19 infection. In this work, we focus on the risk prediction of aortic dissection surgery under the influence of the COVID-19 pandemic. A general scheme of medical data processing is proposed, which includes five modules, namely problem definition, data preprocessing, data mining, result analysis, and knowledge application. Based on effective data preprocessing, feature analysis and boosting trees, our proposed fusion decision model can obtain 100% accuracy for early postoperative mortality prediction, which outperforms machine learning methods based on a singlemodel such as LightGBM,XGBoost, andCatBoost. The results reveal the critical factors related to the postoperative mortality of aortic dissection, which can provide a theoretical basis for the formulation of clinical operation plans and help to effectively avoid risks in advance.
