【摘要】 目的　探讨心源性与非心源性呼吸困难患者B型利钠肽 (BNP)诊断界值水平。方法　采用美国博适 Triage干式快速定量心力衰竭 /心肌梗死诊断仪对 35 1例急性呼吸困难患者床旁BNP测定。 结果　BNP水平 <6 0ng/L患者基本可诊断为非心源性呼吸困难 ;BNP水平 >10 0ng/L但 <5 0 0ng/L患者需考虑心源性呼吸困难可能 ;BNP水平 >5 0 0ng/L患者基本可诊断为心源性呼吸困难。 结论　BNP水平高低是鉴别心源性和非心源性呼吸困难可靠的指标更多还原

【Abstract】 Objective To investigate B type natriuretic peptide (BNP) cut-off point levels in diagnosing cardiac and non-cardiac dyspnea.Methods BNP levels of 351 patients with acute dyspnea were measured by Triage CHF/AMI analyzer made by American Biosite Company.Results At BNP level less than 60 ng/L,non-cardiac dyspnea could generally be diagnosed; At BNP level between 100 ng/L and 500 ng/L,cardiac dyspnea should be considered; At BNP level more than 500 ng/L,cardiac dyspnea could be diagnosed in general condition.Conclusion BNP level is an effective way to identify cardiac and non-cardiac dyspnea.更多还原
