- Abstract: Objective To explore the relationship between plasma insulin-like growth factor-binding protein 2(IGFBP2),secreted modular calcium-binding protein 2(SMOC2)levels and cardiac function and prognosis in patients with chronic heart failure(CHF).Methods A total of 120 CHF patients(the CHF group)and 60 healthy volunteers undergoing physical examination during the same period(the control group)were enrolled.CHF patients were classified according to the New York Heart Association(NYHA)functional classification into the class Ⅱ(46 cases)group,the class Ⅲ group(42 cases)and the class Ⅳ group(32 cases).Based on the 6-month prognosis,patients were further divided into the poor prognosis group(42 cases)and the good prognosis group(78 cases).Plasma IGFBP2 and SMOC2 levels were measured using enzyme-linked immunosorbent assay.The correlation between plasma IGFBP2 and SMOC2 levels with NYHA functional classification was analyzed using Spearman rank correlation.Multivariate unconditional Logistic regression was used to analyze the relationship between plasma IGFBP2 and SMOC2 levels and poor prognosis in CHF patients.The predictive efficacy of plasma IGFBP2 and SMOC2 levels for CHF prognosis was evaluated using receiver operating characteristic(ROC)curve analysis.Results Compared with the control group,plasma IGFBP2 and SMOC2 levels were significantly higher in the CHF group(P＜0.05).Plasma IGFBP2 and SMOC2 levels increased progressively in the class Ⅱ group,the class Ⅲgroup and the class Ⅳ group(P＜0.05).Plasma IGFBP2 and SMOC2 levels were positively correlated with NYHA classification of CHF patients(P＜0.05).The 6-month poor prognosis rate for the 120 CHF patients was 35.00%(42/120).Compared with the good prognosis group,the plasma IGFBP2 and SMOC2 levels were significantly higher in the poor prognosis group(P＜0.05).After adjusting for confounding factors,high levels of IGFBP2 and SMOC2 were independent risk factors for poor prognosis in CHF patients(P＜0.05).The area under the curve(AUC)for the combined prediction of poor prognosis in CHF patients by plasma IGFBP2 and SMOC2 levels was 0.899,which was higher than that of plasma IGFBP2(0.800)and SMOC2(0.782)alone(P＜0.05).Conclusion The plasma levels of IGFBP2 and SMOC2 in CHF patients are increased,which is related to the decrease of cardiac function and poor prognosis.The combination of plasma IGFBP2 and SMOC2 levels has a high predictive efficiency for the prognosis of CHF patients.
