基于超声心动图的急性STEMI患者近期心力衰竭智能预测系统构建及临床应用
Construction and Clinical Application of an Intelligent Prediction System for Short-Term Heart Failure in Patients with Acute STEMI Based on Echocar-diography
摘要
Abstract
Objective To construct an intelligent prediction system for short-term heart failure in patients with acute ST-segment elevation myocardial infarction(STEMI)based on echocardiography,and to explore its clinical application value.Methods The clinical data of 300 patients with acute STEMI admitted to our hospital from January 2022 to April 2024 were retrospectively analyzed.The patients were randomly divided into a training set(n=200)and a validation set(n=100)at a ratio of 2∶1.All patients underwent echocardiographic examination,and the incidence of heart failure within 3 months was recorded.An intelligent heart failure prediction system was constructed using the GoogLeNet Inception-v3 architecture.The predictive performance of physician manual assessment and the intelligent prediction system for short-term heart failure in acute STEMI patients was analyzed,and the consistency between the two prediction methods and actual heart failure occurrence was evaluated using the Kappa test.Results In the validation set,the sensitivity,specificity,and accuracy of physician manual assessment for predicting short-term heart failure were 72.00%,80.00%,and 78.00%,respectively,while those of the intelligent prediction system were 92.00%,88.00%,and 89.00%,respectively.The predictive accuracy of the intelligent system was significantly higher than that of physician manual assessment(P<0.05).The Kappa test showed that both physician manual assessment and the intelligent prediction system had good consistency with actual heart failure occurrence(Kappa values=0.470 and 0.732,respectively;P<0.001),with the intelligent system demonstrating a higher degree of consistency.Conclusions The intelligent prediction system constructed based on echocardiography exhibits good predictive performance for short-term heart failure in acute STEMI patients,outperforming physician manual assessment alone.It can be used for early screening of high-risk heart failure populations in acute STEMI and provides objective imaging references for individualized prevention and treatment.关键词
