血清降钙素原和C反应蛋白测定在心功能不全合并肺部感染患者中的临床价值

摘要

Objective:To evaluate the diagnostic value of chronic heart failure with pulmonary infection early procalcitonin ( procalci-tonin, PCT) .Methods:40 cases of patients with chronic heart failure, according to the clinical pulmonary infection were divided into groups and non-infected groups.All patients admitted to hospital at the time, respectively, after admission blood test PCT, C-reactive protein (C reaction protein, CRP) and leukocyte (white blood cell, WBC) count levels, while sputum culture, chest X -ray, etc. checks.Results:PCT lung infection in patients with positive sputum culture in particular increased significantly, concentrations higher than 0.5 ng /ml, the sensitivity of the diagnosis of chronic heart failure with pulmonary infection was 97% higher than the CRP and WBC.Conclusion:PCT as a judge of chronic heart failure with pulmonary infection early indicator, and may reflect the severity of dis-ease.%目的：探讨降钙素原（ procalcitonin，PCT）对慢性心力衰竭合并肺部感染的早期诊断价值。方法：40例慢性心力衰竭患者，根据临床表现分为合并肺部感染组和非感染组。所有患者入院当时抽血检测PCT、C反应蛋白（ C reaction protein，CRP）和白细胞（ white blood cell，WBC）计数水平，同时行痰培养、胸片等检查。结果：PCT在肺部感染组尤其痰培养阳性患者升高明显，浓度高于0．5 ng／ml，诊断慢性心功能不全合并肺部感染的敏感性为97％，均高于CRP和WBC。结论：PCT可以作为判断慢性心功能不全合并肺部感染的的早期指标，而且可以反映病情程度。
