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351例急性呼吸困难患者床旁BNP测定。 结果 BNP水平小于60pg/ml患者基本可诊断为非心源性呼吸困难;BNP水平大于100pg/ml但小于500pg/ml患者需考虑心源性呼吸困难可能;大于500pg/ml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。Objective To investigate B type natriuretic peptide(BNP) cut-off point levels in diagnosing cardiac and non-cardiac dyspnea. Methods BMP levels of 351 patients with acute dyspnea were measured by Triage CHF/AMI analyzer made by American Biosite Company. Results When BNP level is less than 60pg/ml,non-candiac dyspnea can be diagnosed ;when BNP level is between 100pg/ml and 500pg/ml, cardiac dyspnea should be considered,when BNP level is more than 500pg/ml,cardiac dyspnea can be diagnosed in general condition. Conclusion BNP level is an effective way to identify cardiac and non-car-diac dyspnea.
