快速床边测定B型钠尿肽对心力衰竭危险分层的意义

Rapid Bedside Assay of B-type Natriuretic Peptide in Risk Stratification of Congestive Heart Failure

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 investigate the value of rapid bedside assay of B - type natriuretic peptide （BNP） in risk stratification of heart failure, and to study its prognostic role. Methods Rapid bedside measurement of BNP was applied to determine the plasma BNP levels of 135 patients with heart failure. The patients＇ heart failure was graded by experienced doctors of emergency department according to the HYHA graduation appraisal method; then the results were compared. Re. salts The plasma level of BNP increased when heart failure elevated, the higher the BNP level, the heavier the heart failure degree, the worse prognosis. The plasma level of BNP had significant correlation with the NYHA graduation. Conclusions Rapid bedside assay of BNP is an important measurement for grading and studying the prognosis of congestive heart failure （CHF）.
