摘要(Abstract)：

目的探讨急性心肌梗死(AMI)心肌血流再灌注水平与血浆脑钠肽(BNP)水平的关系及其临床意义。方法对67名AMI成功行急诊介入治疗(PCI)的患者分别进行TIMI心肌灌注分级(TMPG)、心肌灌注显影分级(MBG)和校正的TIMI血流帧数计数(CTFC),采用荧光免疫抗原抗体结合方法测定发病24h即刻血浆脑钠肽(BNP)水平并评价其相互关系。结果TMPG方法评定的心肌灌注水平中,TMPG0/1级组12例,TMPG2级组29例,TMPG3级组26例,其对应血浆BNP平均水平分别为(1026±1119)ng/L,(346±192)ng/L和(219±95)ng/L。各组间血浆BNP水平差异有统计学意义(P=0·001)。其中TMPG0/1级组血浆BNP水平分别高于TMPG2级组和TMPG3级组(P<0·01,P<0·001);TMPG2级组高于TMPG3级组(P<0·01)。MBG方法评定的心肌灌注水平中,MBG0/1级组22例,MBG2级组25例,MGG3级组20例,其对应血浆BNP平均水平分别为(735±886)ng/L,(343±137)ng/L和(148±65)ng/L。各组间血浆BNP水平差异有统计学意义(P<0·001)。其中MBG0/1级组血浆BNP水平分别高于MBG2级组和MBG3级组(P<0·05,P<0·001);MBG2级组高于MBG3级组(P<0·001)。CTFC方法评定的冠脉血流中CTFC>40帧组20例,CTFC≤40帧组47例,血浆BNP平均水平分别为(453±265)ng/L和(397±650)ng/L,CTFC>40帧组血浆BNP水平高于CTFC≤40帧组(P=0·0036)。结论AMI患者心肌血流再灌注水平与血浆BNP水平负相关,再灌注水平越低组血浆BNP水平越高。心肌缺血损伤是BNP释放的重要刺激因素。
