摘要：

目的观察急性心肌梗死(AMI)后血B-型尿钠肽(BNP)水平升高的特点,探讨AMI后BNP水平升高的意义。方法连续入选住院AMI患者230例及正常对照111例进行BNP测定。按照首次或再发AMI后ST段抬高型或非ST段抬高型AMI(STEMI或NSTEMI)、不同部位AMI、不同冠状动脉病变、不同梗死相关血管(IRA)、IRA不同TIMI血流和是否急诊经皮冠状动脉介入治疗(PCI)进行分组,采用Student-t检验和ANOVA分析对比各组间BNP水平和心功能相关指标的差异。结果AMI后2～7天,患者BNP水平显著升高(P<0.01),平均为(553.7±735.1)ng/L,是对照组的21倍;与首次AMI组对比,再发组左室射血分数(LVEF)显著降低(P<0.01),左室舒张末径(LVEDd)、BNP水平和LnBNP均显著升高(P均<0.01);与无显著狭窄病变AMI患者对比,单支、三支血管狭窄组的BNP水平显著为高(P均<0.05);IRA的TIMI血流0～1、2级组BNP水平均显著高于TIMI血流3级组(P均<0.01);与未急诊PCI组对比,急诊PCI组血肌酸激酶同工酶(CK-MB)、肌钙蛋白T(TnT)虽显著升高(P<0.05～0.01),然BNP水平显著降低(P<0.05)。结论AMI后,血BNP水平显著升高。以再发AMI、未行急诊PCI治疗和IRA血流TIMI0～2级者更高。急诊PCI可出现心肌酶升高,而BNP降低的矛盾现象。
