目的评估床边快速测定B型钠尿肽(BNP)对心力衰竭患者危险分层判断预后的作用。方法应用快速检测方法测定135例心衰患者的血浆BNP水平,并由有经验的急诊科医师按照HYHA分级评估心力衰竭分级并对照分级结果。结果BNP在心力衰竭时升高,并与NYHA分级有明显相关性,BNP水平越高,心衰程度越重,预后越差。结论BNP是判断心力衰竭(CHF)患者心功能分级及预后的重要指标。
Objective To evaluate the effect of bedside rapid determination of B-type natriuretic peptide (BNP) on prognosis of patients with heart failure in risk stratification. Methods Fast plasma BNP levels were measured in 135 patients with heart failure by rapid test. Heart failure was graded and controlled by experienced emergency physicians according to HYHA classification. Results BNP increased in heart failure and was significantly associated with NYHA classification. The higher the BNP level, the more severe the heart failure, the worse the prognosis. Conclusion BNP is an important index to judge the grade and prognosis of heart failure in patients with heart failure.
