脑钠肽在急性呼吸困难鉴别诊断中的价值

The value of brain natriuretic peptide in the diagnosis of acute dyspnea

目的探讨急诊检测脑钠肽(BNP)在急性呼吸困难鉴别诊断中的临床价值。方法选择因"急性呼吸困难"来院的患者143例,急诊送检血浆BN P水平,分析其在心源性和肺源性呼吸困难中的水平差异。结果心源性呼吸困难组的BNP水平明显高于肺源性呼吸困难组;纽约心功能Ⅳ级组的BNP水平高于心功能Ⅲ级组;收缩性心功能不全与舒张性心功能不全的BN P水平无差异。结论急诊检测血浆BNP水平能准确鉴别心源性或肺源性引起的急性呼吸困难。

Objective To discuss the value of brain natriuretic peptide in the diagnosis of acute dyspnea.Methods 143 cases of acute dyspnea were involved.The BNP were detected and analyzed the difference levels of between cardiac dyspnea and pulmonary.Results The level of BNP in patients with acute cardiac dyspnea was much higher than those with acute pulmonary dyspnea.The level of BNP in patients with NYHA IV was obviously higher than those with NYHA III.There was no significant difference in the level of BNP between diastolic heart failure and systolic heart failure.Conclusion The level of BNP is an index in distinguishing acute cardiac dyspnea from acute pulmonary dyspnea.
