血清胱抑素C与肌酐在评估75岁以上老年慢性心衰患者预后中的价值
Prognostic value of cystatin C and creatinine in chronic heart failure in patients aged over 75 years
摘要
Abstract
ABSTRACT:Objective To compare the prognostic value of cystatin-C (Cys-C)and creatinine (Cr)in chronic heart failure (CHF)in old people.Methods We recruited 183 old patients (>75 years)diagnosed with CHF hospitalized at the Department of Cardiology and the Department of Geriatrics of our hospital from 2010 to 2012. Venous blood was withdrawn to detect the expressions of Cys-C and Cr.After three-year follow-up,the patients’ three-year survival was recorded.Logistic regression model was used to examine the relationship of Cys-C,Cr and other risk factors with the CHF patients’mortality.ROC curve was used to compare the prognostic value of Cys-C and Cr in CHF in old people and statistical method was adopted to analyze the combined use of Cys-C and Cr for determining their value in evaluating CHF prognosis.Results At the end of the follow-up,74 (40.44%)patients died.Serum cys-C and Cr levels of the patients in death group increased compared with those in survival group (P<0.05).Multivariate logistic regression showed that age (OR=1.11,95% CI=1.04-1.19),SBP (OR=1.06,95%CI=1.01-1.10),LVEF (OR=0.89,95% CI=0.82-0.95),BNP (OR=4.74,95% CI=1.77-12.69), creatinine (OR=2.04,95% CI=1.03-4.08),and Cys-C (OR=2.97,95% CI=1.44-6.12)were the independent risk factors for the prognosis of CHF.ROC analysis showed that Cys-C was superior to creatinine in AUC value (0.71 vs.0.65;95% CI,0.64-0.78;95% CI,0.58-0.72)(P<0.001).The AUC value of Cys-C and Cr in combination was 0.73 (95% CI,0.66-0.79).Conclusion Cys-C is a stronger predictor of the prognosis of CHF patients than creatinine and the combination of the two can increase the sensitivity and specificity in evaluating the prognosis of patients with CHF.关键词
