Correlation of NT-pro BNP,Hcy and Apo-A with Heart Failure Degree and Prognosis in Patients with Acute Myocardial Infarction
Objective:To investigate the correlation between N-terminal pro-brain natriuretic peptide(NT-pro BNP),homocysteine(Hcy)and apolipoprotein A(Apo-A)and the heart failure(HF)degree and prognosis in patients with acute myocardial infarction(AMI).Methods:100 patients with AMI admitted to our hospital from January 2021 to December 2023 were selected as the research objects,and were divided into the HF group(n=44)and the non-HF group(n=56)according to whether they had HF.Serum NT-pro BNP,Hcy and Apo-A levels of all patients were detected,and the HF degree of patients in the HF group was evaluated by Killip grad-ing.Patients in the HF group were divided into good prognosis group(n=24)and poor prognosis group(n=20)according to the progno-sis.The influencing factors of poor prognosis of AMI patients were analyzed by univariate and multifactorial analysis,and the receiver operating curve(ROC)was used to analyze the prognostic value of serum NT-pro BNP,Hcy and Apo-A levels in patients with AMI com-bined with HF.Results:The levels of serum NT-pro BNP,Hcy and Apo-A of patients in the HF group were higher than those in non-HF group(P<0.05).The levels of serum NT-pro BNP,Hcy and Apo-A of patients in HF grade Ⅳ group were higher than those in gradeⅢ and grade Ⅱ groups,and the levels of serum NT-pro BNP,Hcy and Apo-A of patients in HF grade Ⅲ group were higher than those in grade Ⅱ group(P<0.05).Spearson correlation analysis showed that serum NT-pro BNP,Hcy and Apo-A levels were positively corre-lated with HF degrees(r=0.612,0.505,0.649,P<0.05).There were statistically significant differences in age,history of hyperlipid-emia,cardiac enlargement,NT-pro BNP,Hcy and Apo-A levels between the two groups of patients(P<0.05).Logistic regression analysis showed that age,NT-pro BNP,Hcy and Apo-A levels were the prognostic factors of AMI patients with HF(P<0.05).The AUC of serum NT-pro BNP level in predicting prognosis of AMI patients with HF was 0.769(0.617-0.882),the sensitivity was 75.00%,and the specificity was 79.17%(P<0.05).The AUC of serum Hcy level in predicting prognosis of AMI patients with HF was 0.833(0.690～0.928),the sensitivity was 95.00%,and the specificity was 58.33%(P<0.05).The AUC of serum Apo-A level in pre-dicting prognosis of AMI patients with HF was 0.877(0.743-0.957),the sensitivity was 85.00%,and the specificity was 91.67%(P<0.05).Conclusion:Serum NT-pro BNP,Hcy and Apo-A levels increase with the increase of the degree of HF in AMI patients,which are closely related to the prognosis of AMI patients with HF and have high predictive value.
