摘要

摘要: 目的:探讨降钙素原(PCT)测定在老年心力衰竭合并肺部感染中的临床意义及诊断界值。方法:回顾性分析老年心力衰竭合并肺部感染101例,单纯心力衰竭、单纯肺部感染及正常对照组各100例的PCT值,分析PCT诊断肺部感染的灵敏度、特异度、阳性预测值和阴性预测值。结果:心力衰竭合并肺部感染组PCT值高于单纯心力衰竭组PCT值及正常对照组PCT值(均P<0.05);单纯心力衰竭组PCT值低于单纯肺部感染组,但高于正常对照组(均P<0.05);单纯肺部感染组PCT值高于正常对照组(P<0.05)。心力衰竭合并肺部感染组患者PCT单侧95%参考值(P5)>0.03ng/ml,最佳诊断界值为0.14ng/ml。结论:PCT对老年心力衰竭合并肺部感染患者的识别有一定参考价值。

Abstract: Objective:To evaluate the diagnostic value of surem procalcitonin in elderly heart failure complicated with pulmonary infection and to achieve the cutoff value of procalcitonin.Method:One hundred and one patients with heart failure complicated with pulmonary infection,100 patients with heart failure,100 patients with pulmonary infection and 100 controls were included,the sensitivity,specificity,positive predictive value and negative predictive value of PCT in the diagnosis of pulmonary infection were analyzed.Result:The level of PCT in heart failure complicated with pulmonary infection group was significantly higher than that in heart failure group and normal control group(both P<0.05).The level of PCT in heart failure group was lower than that in pulmonary infection group,but higher than that in normal control group(both P<0.05).The level of PCT in simple pulmonary infection group was higher than in normal control group(P<0.05).The unilateral 95% reference range(P5)in heart failure complicated with pulmonary infection group was 0.03ng/ml(>0.03ng/ml).The ROC curve's cutoff value was 0.14ng/ml.Conclusion:PCT has a certain reference value for the identification of the elderly patients with heart failure complicated with pulmonary infection.
