目的:探讨心力衰竭患者NYHA心功能分级与B型钠尿肽(BNP)的关系。方法:对150例心衰患者测定BNP。结果:随心力衰竭患者的NYHA心功能分级的增加,BNP水平呈增高趋势。不同NYHA心功能分级患者的BNP水平差异有统计学意义(P<0.01)。结论:心力衰竭患者BNP水平与NYHA心功能分级有关。
Objective: To investigate the relationship between NYHA functional class and B-type natriuretic peptide (BNP) in patients with heart failure. Methods: BNP was measured in 150 patients with heart failure. Results: With the increase of NYHA functional class in patients with heart failure, the level of BNP increased. The BNP levels in patients with NYHA classifications were significantly different (P <0.01). Conclusion: The BNP level in patients with heart failure is related to NYHA cardiac function classification.
