摘要 目的探讨急性心肌梗死(AM I)患者在分别采用药物和介入治疗后,使用低分子肝素(LMWH)抗凝治疗中,血浆组织因子(TF)和组织因子途径抑制物(TFPI)含量的变化及临床意义。方法选择20例AM I患者和10例正常人(作对照)作为研究对象。采用ELISA法测定血浆中的TF和TFPI含量。其中20例AM I患者中10例采用药物治疗,10例行急诊介入治疗,均加用LMWH抗凝治疗并分别于即刻,LMWH注射后4h、24h、7d后采静脉血测定TF和TFPI含量。结果①AM I患者TF和TFPI含量明显高于对照组(P<0.01);②LMWH注射后4h保守治疗组的TF含量明显降低(P<0.01),但介入治疗组中未见降低。两组的TFPI含量均显著升高(P<0.01)。在LMWH注射后24h即第3次注射前两组患者的TF和TFPI水平都基本回到基线水平;③在治疗7天后药物治疗组的TFPI含量明显升高(P<0.05),两组的TF含量有下降趋势但无统计学意义。结论AM I患者存在高凝状态,LMWH的抗凝作用与降低TF水平并有促进TFPI释放的特性有关。
