超声影像组学对ST段抬高型心肌梗死患者再灌注治疗后心肌损伤评估的价值
Value of Ultrasound Radiomics in Assessing Myocardial Injury after Reperfu-sion Therapy in Patients with ST-Segment Elevation Myocardial Infarction
摘要
Abstract
Objective To investigate the value of ultrasound radiomics in evaluating myocardial injury after reperfusion therapy in patients with ST-segment elevation myocardial infarction(STEMI).Methods The clinical data of 100 STEMI patients who underwent percutaneous coronary intervention(PCI)at our hospital from February 2023 to January 2026 were retrospectively analyzed.According to the presence of microvascular obstruction or intramyocardial hemorrhage,the patients were divided into myocardial injury group(52 cases)and non-myocardial injury group(48 cases).Transthoracic echocardiography was performed on the 4th day after PCI,and the diagnostic value of the Rad-score and conventional echocardiographic parameters for myocardial injury after reperfusion was assessed.Results The Rad-score,E/e',and left atrial volume index in the myocardial injury group were higher than those in the non-myocardial injury group,while LVEF,GLS,and e'were lower than those in the non-myocardial injury group(all P＜0.05).Multivariate Logistic regression analysis showed that Rad-score,decreased GLS,and elevated E/e'were independent risk factors for myocardial injury after STEMI reperfusion(P＜0.05).The areas under the curve(AUC)of Rad-score,GLS,E/e',and the combined model for diagnosing myocardial injury after reperfusion in STEMI patients were 0.855,0.806,0.820,and 0.933,respectively.The AUC of the combined model was significantly higher than those of Rad-score,GLS,and E/e'alone(P＜0.05).Conclusions Rad-score,GLS,and E/e'are closely associated with myocardial injury after reperfusion in STEMI patients,and their combined application can improve the diagnostic value.关键词
