血浆D-二聚体在老年急性肺栓塞早期诊断中的应用分析

Plasma D-dimer in the Old in the Early Diagnosis of Acute Pulmonary Embolism

目的探讨血浆D-二聚体在老年急性肺栓塞诊断中的临床价值。方法采用自动免疫分析系统快速定量检测血浆D-二聚体法,对30例急性老年肺栓塞患者血浆中纤维蛋白降解产物D-二聚体进行检测,并与30例健康体检者血浆D-二聚体水平对比。结果肺栓塞组患者血浆DD(549.5±27.3)ng/ml,>230 ng/ml者30例,阳性率90%。对照组(124.3±15.1)ng/ml。两组血浆D-二聚体平均值相比较有差异统计学意义(P<0.05)。结论血浆D-二聚体对老年急性肺栓塞早期诊断有一定帮助。

Objective To study the plasma D-dimer clinical value in the diagnosis of senile acute pulmonary embolism. Methods Automatic immunoassay system fast quantitative detection of plasma D-dimer method, 30 cases of elderly acute pulmonary embolism in patients with plasma fibrin degradation product D-dimer for testing, and compared with 30 cases of healthy check-up plasma D-dimer level contrast. Results The patients with pulmonary embolism group plasma DD （549.5 ±27.3） ng/ml, 30 cases〉230 ng/ml, positive rate was 90%. In the control group （124.3± 15.1） ng/ml. Two groups of plasma D-dimer average compared with statistically significant difference （P〈0.05）. Conclusion Plasma D-dimer of elderly acute pulmonary embolism has certain help early diagnosis.
