The purpose of the study is to study the possibility of using neural network analysis to predict the fact and degree of coronary lesion. The task of the study was to compare the accuracy of the trained neural network model on input structured data and ECG records with the conclusion of a cardiologist.

Material and methods: 120 patients who underwent elective or emergency coronary angiography. To predict the damage to the coronary bed, the method of neural network analysis was used. Machine learning was performed with the inclusion of clinical, laboratory, instrumental (ECG-image) signs (23 indicators in total). To solve classification problems, a neural network was used that takes structured data and an image as input and outputs a multifactorial characteristic of the main coronary arteries.

The training/test ratio in the examples was 100/20. The supervised learning method was used on the available data, in which the outcomes were known (coronary angiography data), and the neural network parameters were adjusted so as to minimize the error using the backpropagation method. For this experiment, based on the test sample, 20 tasks were created. An ECG image was attached to each task.

5 cardiologists, daily supervising patients with acute coronary syndrome, separately assessed the pathology of the coronary bed for each main coronary artery and predicted the need for revascularization.

Results: The results of the neural network on a test sample of 20 patients: AUC score - 0.74, accuracy (accuracy) - 80%, precision accuracy (precision) - 63%, recall (recall) - 55%, f1 score (harmonic mean between accuracy and completeness) - 59%. Average response rates of cardiologists: accuracy - 76%, precision - 48%, recall - 55%, AUC score - 0.68, f1 score - 49%. The best values of cardiologists: accuracy - 76%, precision - 48%, recall - 67%, AUC score - 0.72, f1 score - 56%.

Conclusion: Neural network analysis of the prepared clinical, laboratory and instrumental data allows you to adjust the network parameters for subsequent accurate prediction of coronary artery disease. The results obtained in the form of an AUC score allow us to speak about the applicability of the method in the diagnosis of coronary pathology. On the test sample, the neural network works more efficiently than cardiologists on average. Only one in five specialists was able to come close to the accuracy of the trained neural network model.
