摘  要:目的通过测定急性心肌梗死(AMI)患者直接经皮冠状动脉介入治疗(PCI)前后血浆组织因子(TF)、组织因子途径抑制物(TFPI)水平的变化,探讨TF、TFPI与无再流的关系。方法选择2006年5月至2007年5月于我院急诊行PCI的AMI患者53例,用ELISA法检测患者PCI术前、术后即刻、术后24h外周静脉血TF、TFPI水平。比较其中无再流者与再灌流者不同时点TF、TFPI水平的变化。结果PCI术前、术后即刻、术后24h无再流组血浆TF、TFPI水平均明显高于再灌流组[TF(275.3±46.2)ng/L比(236.8±44.3)ng/L、(332.7±41.3)ng/L比(282.3±38.7)ng/L、(315.5±47.8)ng/L比(248.1±46.9)ng/L;TFPI(165.2±38.4)μg/L比(128.5±18.7)μg/L、(176.3±36.8)μg/L比(135.6±20.3)μg/L、(149.8±31.7)μg/L比(118.7±19.2)μg/L;均P〈0.01];PCI术后即刻,两组TF水平均较术前明显升高(P〈0.01);PCI术后24h,无再流组TF水平仍高于术前水平(P〈0.05),再灌流组与术前比较无差异(P〉0.05);PCI前后两组TFPI水平均无明显变化(P〉0.05)。结论AMI患者直接PCI后无再流的发生与血浆TF水平呈正相关,TF可激活外源性凝血途径,形成微血栓而导致无再流,而TFPI可阻止血栓形成而防治无再流的发生。Objective To compare plasma tissue factor (TF) and tissue factor pathway inhibitor (TFPI) levels before, immediately and 24 hours after percutaneous coronary intervention (PCI) in acute myocardial infarction ( AMI ) patients with or without no-reflow. Methods Plasma TF and TFPI in AMI patients underwent PCI were measured by enzyme linked immunoadsorbent ( ELISA ) before, immediately and 24 hours after PCI. Results The levels of TF and TFPI of no-reflow patients (a = 17) were significantly higher than those of reflow patients (n =36) at baseline, immediately and 24 hours after PCIITF: (275.3±46. 2) ng/L vs. (236. 8± 44. 3) ng/L, ( 332. 7 ±41.3 ) ng/L vs. (282. 3 ± 38.7 ) ng/L, (315.5 ±47. 8 ) ng/Lvs. (248.1±46.9) ng/L;TFPI:(165.2±38.4 )μg/Lvs. (128.5±18.7) μg/L,(176.3±36.8) μg/L vs. ( 135.6 ±20. 3 )μg/L, ( 149. 8 ± 31.7 )μg/L vs. ( 118.7 ± 19. 2 ) μg/L ; all P 〈 0. 01 ]. Plasma TF was significantly increased in both groups ( all P 〈 0. 01 ) immediately post PCI and the TF was still higher than that before PCI in no-reflow patients ( P 〈 0. 05 ) and returned to baseline level in fellow patients at 24 hours after PCI ( P 〉 0. 05 ) , TFPI levels were similar before and after PCI in both groups ( all P 〉 0. 05 ). Conclusion Plasma tissue factor and tissue factor pathway inhibitor might play important roles in the development of no-reflow during PCI in AMI patients.
