[Abstract] Objective This paper tries to investigate the clinical value of brain natriuretic peptide in assessing the severity of chronic obstructive pulmonary disease and chronic pulmonary heart disease. Methods 46 patients with acute exacerbation of chronic obstructive pulmonary disease from April 2014 to April 2016 were conveniently enrolled in group A. 46 patients with acute exacerbation of chronic pulmonary heart disease of the same period were enrolled in group B, 46 patients with chronic pulmonary heart disease decompensated patients were in group C. Three groups of blood samples were taken from fasting in the morning and the levels of plasma brain natriuretic peptide were detected by enzyme-linked immunosorbent assay. Results The levels of brain natriuretic peptide was (87.2±30.4)ng/L, brain natriuretic peptide in group B was(224.6±71.5)ng/L, brain natriuretic peptide in group C was (438.1±96.7)ng/L, differences between groups were statistically significant(P0.05),具有可比性。 1.2 纳入与排除
纳入标准[3]:①COPD诊断符合卫生部《慢性阻塞性肺疾病诊疗规范》(2013修订版)相关标准,急性发作期,症状至少同时符合气促加重、痰量增加、脓性痰中的2项,发病至就医≤72 h。②慢性肺源性心脏病诊断符合中华医学会呼吸病学分会制定标准,代偿期与失代偿期诊断参照《内科学》(第8版),以患者有无出现气促加重、心悸、右心衰竭等为划分标准。
排除标准:①肺部恶性病变;②严重肺部感染;③活动性肺结核;④弥漫性支气管炎或支气管扩张;⑤近期心脏或肺部手术者;⑥心肺血管畸形;⑦急性心功能衰竭或重度心律失常;⑧合并免疫疾病、血液疾病等影响血清脑钠肽水平者。
1.3 方法
全部患者均于入院明确诊断次日清晨空腹抽取静脉血液样本,血样采集严格遵照标准采血流程,坚持无菌操作,样本放入EDTA抗凝管中即刻送检,以保证有效性。实验室内,样本常规上机离心5 min,转速3 000 r/min,分离并提取血浆,低温保存。以Triage BNP检测仪及相关试剂测定3组血浆样本中的脑钠肽水平,检测采用酶联免疫吸附法,相关操作严格依照说明书程序指导,质控参数及质量指标均可控。对比观察3组血浆脑钠肽水平差异,指标正常参考值≤30 ng/L。
