Application Value of NT-pro BNP in the Diagnosis of Frailty and Prognostic Assessment in Elderly Heart Failure Patients
Objective:To explore the application value of N-terminal pro-B-type natriuretic peptide(NT-pro BNP)in the diagnosis of elderly heart failure with frailty and assessment of prognosis.Methods:A total of 115 cases of elderly heart failure from January 2020 to March 2022 were selected.According to the Fried frailty diagnostic scale,patients were divided into frailty group,pre-frailty group,and non-frailty group.The diagnostic value of NT-pro BNP level for frailty and its correlation with frailty severity were ana-lyzed.The frailty group was further divided into a better prognosis group and a poor prognosis group based on major adverse events occurring within 12 months of enrollment,and the prognostic value of NT-pro BNP level was analyzed.Results:The levels of NT-pro BNP,BNP,cTnⅠ,CK,and CK-MB in the frailty group,pre-frailty group,and non-frailty group showed a decreasing trend.The indicators in the frailty group were high-er than those in the pre-frailty group,and the pre-frailty group was higher than the non-frailty group(P<0.05).The AUC value of NT-pro BNP level for diagnosing frailty in elderly heart failure patients was 0.773,with a 95%CI of 0.6850.889,P<0.001,sensitivity of 87.10%,and specificity of 70.00%.Conclusion:NT-pro BNP levels are abnormally elevated in elderly heart failure patients with frailty.This marker has diag-nostic value for frailty and prognostic assessment in patients,providing valuable insights into their diagnosis and prognosis.
