脑钠肽和NT—Pro BNP检测在心力衰竭诊断中的意义

目的探讨慢性充血性心力衰竭（CHF）患者血浆B型脑钠肽（BNP）及NT-proBNP改变及其临床意义。方法对该院明确诊断为CHF的120例不同病因、不同心功能分级的慢性充血性心衰患者及50例对照组，测定人院时血浆NT—proBNP及LVEDD、LVESD、LVEF变化，并进行治疗前后对比观察。结果CHF组总体血浆NT-proBNP水平明显高于对照组（P〈0．05），NYHAI级心功能时血浆BNP明显高于对照组（P〈0．05），且Ⅰ、Ⅱ、Ⅲ、Ⅳ级组间血浆BNP依次递增（P〈0．05）。CHF在治疗后明显低于治疗前（P〈0．05）。结论血浆NT-proBNP的水平对CHF的诊断、严重程度和预后评价有重要价值。

Valne of BNP and NT-Pro BNT testing in diagwsis of heart failure

Objective To evaluate the clinical significance of the changes of plasma B-type natriuretic paprid and NT-pro BNP levels in patients with chronic heart failure(CHF).Methods 120 consecutive patients hospitalized for CHF were retrospectively studied.NT-pro BNP and LVEDD,LVESD,LVEF were measured and compared in 120 patients and 50 normal control subjects before medical treatment and on discharge.Results The plasma NT-pro BNP levels in patients with CHF were significantly higher than controls( P <0.05).The plasma NT-pro BNP levels in patients with cardiac function NYHA Ⅰ were significantly higher than controls( P < 0.05).As the cardiac function deteriorated from NYNA Ⅰ to NYNA Ⅳ,the NT-pro BNP levels increased consecutively with significant differences from each other ( P < 0.05).The plasma NT-pro BNP levels was low when CHF was cured ( P < 0.05 ).Conclusion Determination of plasma NT-pro BNP levels in patients with CHF were helpful to study the severity and prognosis of disease.
