Deep Learning Model for Identification of Patients with Acute Heart failure using electrocardiogram in Emergency Room
Abstract Body (Do not enter title and authors here): Background: Acute heart failure (AHF) poses significant diagnostic challenges in emergency room (ER) settings due to its varied clinical presentations and the limitations of traditional diagnostic methods. This study aims to develop and evaluate a deep learning model that uses electrocardiogram (ECG) data to enhance the identification of AHF in ER patients.
Methods: In this retrospective cohort study, we analyzed ECG data from 19,285 patients who visited the ERs of three hospitals between 2016 and 2020. Among the patients, 9,119 patients with available left ventricular ejection fraction and NT-proBNP levels, who were diagnosed with AHF were included. We extracted morphological and clinical parameters from the ECG data to train and validate four machine learning models: a baseline linear regression and more advanced models including XGBoost, Light GBM, and CatBoost.
Results: The CatBoost algorithm outperformed other models, showing superior AUROC and AUPRC diagnostic accuracy across both internal (0.89±0.01 and 0.89±0.01) and external validation datasets (0.90 and 0.89). In addition, the model demonstrated high metrics in accuracy, precision, recall, and f1-score, indicating robust performance in the identification of AHF.
Conclusion: The developed machine learning model significantly enhances the detection of AHF in ER patients using conventional 12-lead ECGs combined with clinical data. These findings suggest that ECGs, a commonplace tool in ERs, can effectively screen for AHF.
