摘要
目的评价B型利钠肽(BNP)水平在心力衰竭患者预后中的作用,探讨和心力衰竭患者预后相关的其他因素;同时验证BNP在鉴别呼吸困难原因中的作用。方法130例因呼吸困难而入院的的患者采用荧光免疫法进行床旁快速BNP检测,根据最后诊断分为心力衰竭组(组1)、非心力衰竭组(组2),并将组1所有患者随访180d,再将心力衰竭组(组1)根据BNP水平分成组1a(BNP值小于200pg/ml)、组1b(BNP值在200pg/ml到500pg/ml之间,包括200pg/ml但不包括500pg/ml)和组1c(BNP值大于等于500pg/ml)。结果BNP、血糖与心力衰竭患者的死亡和再入院的风险显著相关(P=0.003和P=0.001),肌钙蛋白(TnI)与心力衰竭患者的死亡和再人院的风险正相关(P=0.049),左室射血分数(LVEF)与心力衰竭患者的死亡和再入院的风险负相关(P=0.028)。血糖、LVEF、BNP水平和TnI影响心力衰竭患者的生存率。BNP≥500pg/ml心力衰竭患者6个月再入院和死亡的危险性是BNP<500pg/ml心力衰竭患者的4.16倍(P=0.009)。血糖≥7.0mmol/L心力衰竭患者6个月再入院和死亡率为38.6%,显著高于血糖<7.0mmol/L者(3.8%,P=0.000)。LVEF<30%心力衰竭患者的6个月再入院和死亡率为26.5%,显著高于LVEF≥30%心力衰竭患者(12.8%,P=0.050)。TnI≥0.04ng/ml心力衰竭患者的6个月再入院和死亡率为35%,显著高于TnI<0.04ng/ml心力衰竭患者(14.5%,P=0.050)。TnI≥0.04ng/ml的心力衰竭患者,BNP≥500pg/ml者发生再入院和死亡的相对危险度是BNP<500pg/ml者的2.64倍;对于BNP≥500pg/ml的心力衰竭患者,TnI≥0.04ng/ml者发生再入院和死亡的相对危险度是TnI<0.04ng/ml者的1.83倍;TnI≥10.04ng/ml且BNP≥500pg/ml的心力衰竭患者,发生再入院和死亡的危险性是TnI<0.04ng/ml且BNP<500pg/ml的心力衰竭患者的9.5倍(P=0.017)。结论高BNP浓度、高血糖、高TnI值和低LVEF与心力衰竭患者死亡和再入院的高风险相关,BNP浓度、血糖水平、LVEF和TnI值对于心力衰竭患者的预后有重要意义;BNP和TnI联合对心力衰竭患者预后和危险分层意义更大。
