摘要 目的探讨血浆脑钠肽(BNP)、肌酸激酶同工酶(CK-MB)、心肌肌钙蛋白I(cTnI)3种心肌生物标记物的血浆浓度对急性ST段抬高性心肌梗死(STEMI)溶栓患者住院期间心血管事件(包括死亡、心力衰竭、梗死后心绞痛)发生的临床意义。方法以就诊于急诊科、确诊STEMI并溶栓的62例患者为观察对象,以是否在溶栓后发生心血管事件分组,分为发生组和未发生组。收集其血浆BNP、CK-MB、cTnI检验值,记录其在住院期间心血管事件的发生情况,并通过浓度危险分层统计处理。结果心血管事件发生组BNP浓度较未发生组明显升高,两组差异有统计学意义(P<0.01)。两组CK-MB与cTnI浓度差异无统计学意义(P>0.05)。BNP浓度是最强影响心血管事件发生的预测因子(P<0.01,OR=0.989,95%CI:0.984~0.995);同时发现性别(男性)与心血管事件发生有明显相关(P<0.05,OR=0.278,95%CI:0.080~0.967)。年龄、CK-MB峰值以及cTnI与心血管事件无明显相关(P>0.05)。结论血浆BNP浓度对STEMI急诊静脉溶栓后患者住院期间心血管事件(包括死亡、心力衰竭、梗死后心绞痛)的发生具有临床预测价值,而CK-MB与cTnI则不具有临床预测价值。
