Abstract:
Objective:To investigate the diagnostic value of serum homocysteine(Hcy),soluble stromelysin 2(sST2)and cystatin C(CysC)for chronic heart failure(CHF).Methods:A total of 86 CHF patients admitted in our hospital were se-lected as CHF group,and 86 healthy individuals who underwent physical examination simultaneously were selected as healthy control group.Serum levels of Hcy,sST2 and CysC,plasma level of N terminal pro brain natriuretic peptide(NT-proBNP)and cardiac function indexes[left atrial diameter(LAD),left ventricular end diastolic diameter(LVEDd),left ventricular ejection fraction(LVEF)]were measured between two groups.Pearson correlation analysis was used to analyze the correlation among serum Hcy,sST2,CysC,plasma NT-proBNP and cardiac function indexes.Receiver operating characteristic curve(ROC)was drawn to evaluate the diagnostic value of serum Hcy,sST2 and CysC and their combined detection for CHF.Results:Compared with healthy control group,there were significant rise in scrum levels of Hcy,sST2 and CysC,plasma NT-proBNP level,LAD and LVEDd,and significant reduction in LVEF in CHF group,P=0.001 all.Pearson correlation analysis indicated that serum Hcy,sST2 and CysC levels were significant positively correlated with plas-ma NT-proBNP level,LAD and LVEDd(r=0.385～0.511,P＜0.05 or＜0.01),and significant inversely correlated with LVEF(r=-0.424～-0.402,P＜0.05 all).AUC of single detection of serum Hcy,sST2 and CysC diagnosing CHF was 0.624,0.720 and 0.870 respectively,and AUC of their combination was 0.865,which was significantly higher than any single detection,P＜0.05 or＜0.01.Conclusion:Serum levels of Hcy,sST2 and CysC abnormally increase in CHF patients,which can be used as auxiliary diagnostic indexes for CHF.The triple combined detection is of great signifi-cance for the diagnosis of CHF.
