Abstract:
Objective To Study the value of effected ejection fraction(eEF)in assessment of cardiac function in elderly patients with heart failure.Methods A total of 1 134 elderly inpatients in this hospital from January 2019 to December 2023 were selected as the research subjects.After admission,relevant examinations and tests were completed,and the cardiac function classification of the New York Heart Association(NYHA)was carried out.Sequential electrocardiogram(ECG)and echocardiogram examinations were completed before treatment.Age,under-lying diseases,left ventricular ejection fraction(LVEF),N-terminal pro-brain natriuretic peptide(NT-proB-NP),and QT interval(QTc)of the ECG were included for classification and statistics,and eEF was obtained,and the evaluation value of eEF on cardiac function was analyzed.Results The numbers of patients with NY-HA cardiac function grades Ⅰ—Ⅳ were 86,434,454 and 160,respectively,and LVEF decreased with the in-crease of the NHYA cardiac function grade.There was statistically significant differences in LVEF among dif-ferent NHYA cardiac function classifications(P＜0.05).The QTc of the patients was(434.71±40.96)ms,the eEF was(8.73±2.03)ms,and the ln(NT-proBN)was 7.05±1.70.QTc,eEF,and ln(NT-proBN)all in-creased with the increase of the NHYA cardiac function classification,and there were statistically significant differences in indicators above among different NHYA cardiac function classfications(P＜0.05).There was a low correlation between QTc of the ECG,age and cardiac insufficiency(r＜0.5,P＜0.05);there was a high correlation between eEF,LVEF,and ln(NT-proBNP)and cardiac insufficiency(r≥0.5,P＜0.05).Conclusion eEF still has discriminatory value for patients with heart failure with preserved ejection fraction,and it is a good indicator for evaluating the cardiac function of elderly patients with heart failure.
