Abstract

目的探讨慢性心力衰竭患者血浆脑钠素(BNP)浓度的变化.方法用放射免疫法测定56例慢性心衰患者(CHF组)及60名健康体检者(对照组)的血浆BNP浓度,用放射性核素99m锝心血池扫描测定慢性心衰者左心室射血分数.结果慢性心衰患者血浆BNP浓度(222.65±78.52 ng/L)显著高于正常对照组(39.82±1 5 3ng/L)(P＜0.01),且随着心功能分级的程度加重而增加.血浆BNP浓度与左心室射血分数(LVEF)之间存在较良好的负相关(r=-0.68,P＜0.01).结论慢性心衰患者血浆BNP浓度升高,且随心衰严重程度的增加而显著升高.心衰患者血浆BNP浓度能较好地反映左心室功能状态.
