摘要
目的:探讨血清同型半胱氨酸(Hcy)、可溶性基质裂解素2(sST2)和胱抑素C(CysC)对慢性心力衰竭(CHF)的诊断价值.方法:选择本院收治的86例CHF患者作为CHF组,选择同期体检健康者86例作为健康对照组.检测两组血清Hcy、sST2、CysC水平、血浆氨基末端脑钠肽前体(NT-proBNP)和心功能指标[左房内径(LAD)、左室舒张末期内径(LVEDd)、左室射血分数(LVEF)]并进行比较,采用Pearson相关分析血清Hcy、sST2和CysC与NT-proBNP、心功能指标的相关性,并绘制受试者工作特征(ROC)曲线评估血清Hcy、sST2和CysC联合检测对CHF的诊断价值.结果:与健康对照组比较,CHF组血清Hcy、sST2、CysC水平,血浆NT-proBNP水平和LAD、LVEDd均显著增加,LVEF显著降低(P均=0.001).血清Hcy、sST2和CysC水平与血浆NT-proBNP 水平、LAD、LVEDd 均呈显著正相关性(r=0.385～0.511,P＜0.05 或＜0.01),与 LVEF 呈显著负相关(r=-0.424～-0.402,P均＜0.05).血清 Hcy、sST2 和 CysC 单项检测诊断 CHF 的 AUC 分别为 0.624、0.720和0.807,三项指标联合检测诊断CHF的AUC为0.865,显著大于各指标单独检测(P＜0.05或＜0.01).结论:血清Hcy、sST2和CysC水平在CHF患者中异常升高,可作为CHF辅助诊断指标,三者联合检测对CHF的诊断具有重要意义.
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.
