Abstract:

Objective To investigate the roles of miR-10a and miR-16 expressions in the occurrence of major adverse cardiovascular events(MACE)in elderly patients with chronic heart failure(CHF). Methods A total of 158 elderly CHF patients from Ruijin Rehabilitation Hospital from January 2021 to January 2023 were enrolled,including 98 patients with heart failure with mildly reduced ejection fraction(HFmrEF)and 60 patients with heart failure with preserved ejection fraction(HFpEF). The clinical data at admission were collected,and relevant laboratory indicators and serum relative expression levels of miR-10a and miR-16 were determined. All the patients were followed up for 1 year,and they were classified into MACE group and non-MACE group according to whether MACE occurred. Spearman correlation analysis or Pearson correlation analysis was used to evaluate the correlation between various indicators. Multivariate Logistic regression analysis was used to evaluate the influencing factors of MACE in elderly CHF patients. Receiver operating characteristic(ROC)curve was used to evaluate the efficacy of various indicators in judging the occurrence of MACE in elderly CHF patients. Results The relative expression levels of serum miR-10a and miR-16 and the level of cTnI,as well as the proportion of NYHA class Ⅲ-Ⅳ,in MACE group were higher than those in non-MACE group(P<0.05),and the LVEF level was lower than that in non-MACE group(P<0.05). There was no statistical significance in the other indicators between the 2 groups(P>0.05). The relative expression levels of serum miR-10a and miR-16 were positively correlated with NYHA classification(r values were 0.516 and 0.504,respectively),cTnI(r values were 0.528 and 0.529,respectively),and they were negatively correlated with LVEF(r values were -0.510 and -0.525,respectively,P<0.05). Elevated expressions of miR-10a and miR-16 were independent risk factors for MACE in elderly CHF patients [odds ratios(OR)were 2.849 and 2.916,95% confidence intervals(CI)were 1.534-5.293 and 1.420-5.987,P<0.01]. The areas under curves(AUC)of single determinations of serum miR-10a,miR-16,cTnI,LVEF and combined determination of miR-10a and miR-16 for judging the occurrence of MACE in elderly CHF patients were 0.843,0.808,0.845,0.866 and 0.921,respectively. Conclusions The upregulation of serum miR-10a and miR-16 expressions is related to the occurrence of MACE in elderly CHF patients,and they may be used as assessment indicators for the prognosis risk of elderly CHF patients.
