【摘要】目的探讨N-末端脑钠肽前体(NT-proBNP)对心源性和肺源性呼吸困难的鉴别诊断价值。方法用酶免疫分析法测定128例呼吸困难患者血浆中NT-proBNP水平,包括心源性呼吸困难和肺源性呼吸困难, 观察两组患者血浆NT-proBNP的水平。同时测定20例健康体检者的NT-proBNP水平作为对照组做比较分析。结果两组患者的血浆NT-proBNP水平,心源性呼吸困难组(1372.68±944.98)ng /L明显高于肺源性呼吸困难组(586.00±85.00)ng/L,两组差异有统计学意义(P<0.05)。结论NT-proBNP可作为鉴别心源性呼吸困难和肺源性呼吸困难的一个客观指标, 其方法简单迅速、特异性好、敏感性高, 具有很高的临床意义。
