Objective:To investigate the predictive value of cardiac ultrasound for adverse events in patients with a-cute heart failure(AHF).Methods:A total of 100 AHF patients admitted to our hospital from November 2021 to December 2022 were selected.Color Doppler echocardiography was used to detect cardiac function indexes in all pa-tients,including mitral early diastolic peak velocity(E)and late peak velocity(A),and E/A ratio was calculated,left ventricular ejection fraction(LVEF)and Tei index.According to occurrence of adverse events within six-month follow-up or not,they were divided into event group(n=36)and no event group(n=64).E/A,LVEF and Tei index were compared between two groups.Receiver operating curve(ROC)was plotted to analyze the pre-dictive value of E/A,LVEF,Tei index and their combined detection for adverse events in AHF patients.Results:All AHF patients completed 6-month follow-up,including 28 cases of readmission due to heart failure and 8 cases of death.Compared with no event group,there were significant reductions in E/A[(0.98±0.10)vs.(0.79± 0.16)]and LVEF[(42.63±4.89)％vs.(37.86±4.41)％],and significant rise in Tei index[(0.44±0.27)vs.(0.58±0.21)]in event group,P＜0.01 all.Logistic regression model suggested that age and Tei index were inde-pendent risk factors for adverse events in AHF patients(OR=3.728,6.878,P=0.001 both),while E/A and LVEF were its independent protective factors(OR=0.519,0.350,P＜0.05 or＜0.01).The AUC of combined detection of E/A,LVEF and Tei index predicting adverse events in AHF patients was 0.903,significantly higher than that of LVEF alone(Z=2.207,P=0.043).Conclusion:The combined detection of E/A,LVEF and Tei in-dex possesses high predictive value for adverse events in AHF patients,which can be used as a new program for clini-cal prediction of AHF prognosis,so as to take corresponding treatment as soon as possible and improve prognosis.
