简介：目的：探讨老年心力衰竭（CHF）患者心功能与血浆B型钠尿肽（BNP）和血尿酸的相关性。方法选择132例老年CHF患者作为CHF组，并按心功能分级（NYHA）Ⅰ级26例、Ⅱ级38例、Ⅲ级40例、Ⅳ级28例。同期选择健康体检者50例作为对照组。分别测定血浆BNP及血尿酸水平，比较不同心功能级别入选患者的血浆BNP水平和血尿酸水平。结果CHF组患者血浆BNP和血尿酸水平明显高于对照组，差异有统计学意义[（784．19±206．00）ng/Lvs（41．25±15．34）ng/L，（405．24±90．16）μmol/Lvs（286．43±78．68）μmol/L，P＜0．01]；不同心功能分级患者血浆BNP和血尿酸水平两两比较，差异有统计学意义（P＜0．05，P＜0．01）；CHF时，BNP与心功能分级、血尿酸、左心室舒张末内径（LVEDD）呈正相关（r＝0．76、0．33、0．22，P＜0．05）；与LVEF呈负相关（r＝-0．34，P＜0．05）；尿酸与心功能分级、LVEDD呈正相关（r＝0．41、0．23，P＜0．05）；与LVEF呈负相关（r＝-0．24，P＜0．05）。结论血浆BNP和血尿酸水平与心功能分级可能具有相关性。
