摘要
目的 观察合并高血压病的冠心病患者行经皮冠状动脉介入(PCI)术治疗后血栓形成前状态分子标志物的变化并分析其意义.方法 选择32例冠心病患者(A组)及38例冠心病合并高血压病患者(B组)进行PCI,分别在介入治疗前与治疗后20 min、24 h及7 d采血测定血栓形成前状态分子标志物水平,并动态随访PCI后冠状动脉病变再狭窄的情况.结果与术前比较,A组术后20 min血清von Willebrand因子(vWF)、凝血因子Ⅷ抗原(Ⅷ:Ag)、抗凝血酶Ⅲ(ATⅢ)、血浆血小板颗粒膜糖蛋白140、蛋白C、凝血酶活性(F.Ⅱa)、血浆纤维蛋白原(Fbg)、血清纤溶酶原(Plg)、血浆组织型纤溶酶原激活剂(t-PA)、纤溶酶原激活剂抑制物(PAI)、D-二聚体水平及术后24 h vWF、蛋白C、Fbg、Plg、PAI、D-二聚体水平均有明显改变[术前:(54±19)%、(69±16)%、(208±33)mg/L、(14±3)μg/L、(4.1±0.9)mg/L、(0.46±0.12)kU/L、(4.6±1.1)g/L、(181±42)mg/L、(0.26±0.06)kIU/L、(0.37±0.09)kAU/L、(0.53±0.15)mg/L;术后20 min:(94±34)%、(89±26)%、(188±31)mg/L、(20±5)μg/L、(3.3±1.3)mg/L、(0.58±0.17)kU/L、(5.6±1.3)g/L、(162±45)mg/L、(0.38±0.09)kIU/L、(0.48±0.13)kAU/L、(0.89±0.28)mg/L;术后24 h:(75±20)%、(3.5±0.8)mg/L、(5.3±1.1)g/L、(167±43)mg/L、(0.43±0.11)kAU/L、(0.78±0.19)mg/L],差异均有统计学意义(P〈0.05或P〈0.01);术后7 d PCI后血栓形成前状态(PTS)分子标志物与术前比较,差异无统计学意义(P〉0.05).B组术后20 min、24 h、7 d vWF、Ⅷ:Ag、ATⅢ、GMP140、蛋白C、F.Ⅱa、Fbg、PAI、D-二聚体水平均较术前有明显变化[分别为:(135±37)%、(128±33)%、(88±19)%比(70±18)%,(120±30)%、(99±24)%、(88±22)%比(77±20)%,(157±34)、(161±31)、(164±33)mg/L比(187±33)mg/L,(23±7)、(22±6)、(20±4)μg/L比(17±4)μg/L,(2.1±1.1)、(2.2±0.7)、(2.5±0.8)mg/L比(3.0±1.1)mg/L,(0.79±0.19)、(0.74±0.18)、(0.69±0.16)kU/L比(0.61±0.16)kU/L,(6.6±1.7)、(6.4±1.8)、(6.1±1.7)g/L比(5.2±1.2)g/L,(0.68±0.15)、(0.66±0.15)、(0.57±0.18)kAU/L比(0.47±0.15)kAU/L,(1.22±0.34)、(1.10±0.30)、(0.94±0.22)mg/L比(0.68±0.18)mg/L],差异均有统计学意义(P〈0.05或P〈0.01).术后20 min、24 h、7 d,B组与A组vWF、Ⅷ:Ag、ATⅢ、GMP140、蛋白C、F.Ⅱa、Fbg、Plg、t-PA、PAI、D-二聚体水平差异均有统计学意义(P〈0.05或P〈0.01).结论 冠心病患者PCI后出现血栓形成前状态分子标志物指标的变化,这种变化在合并高血压病的患者中更加明显,表明冠心病患者PCI术后存在明显的血栓形成前状态,而高血压可以促进这一状态产生.
Objective To observe the changes of molecular markers of pre-thrombotic state in coronary heart disease (CHD) patients complicated with hypertension (HBP) undergoing percutaneous coronary intervention (PCI). Methods Thirty-two cases with CHD(group A) and 38 cases with CHD and HBP (group B) underwent PCI; molecular markers of pre-thrombotic state were measured before and 20 minutes, 24 hours, 7 days after PCI. The patients were followed up regarding restenosis of the coronary arteries after PCI. Results Compared to before PCI, there were significant changes of von willedrand factor(vWF), coagulation factor Ⅷ antigen(Ⅷ:Ag), antithrombinⅢ(ATⅢ), the plasma platelet granule membrane protein 140 (GMP140), protein C, thrombin activity(F.Ⅱa), plasma fibrinogen(Fbg), serum plasminogen(Plg), the plasma levels of tissue type plasminogen activator(t-PA), plasminogen activator inhibitor(PAI), D-Dimer [(94±34)%,(89±26)%,(188±31)mg/L,(20±5)μg/L, (0.58±0.17)kU/L,(5.6±1.3)g/L,(162±45)mg/L,(0.38±0.09)kIU/L,(0.48±0.13)kAU/L,(0.89±0.28)mg/L, respectively, P〈0.05 or P〈0.01] 20 min after PCI, and vWF, protein C, Fbg, Plg, PAI, D-Dimer [(75±20)%,(3.5±0.8)mg/L,(5.3±1.1)g/L,(167±43)mg/L,(0.43±0.11)kAU/L,(0.78±0.19)mg/L, respectively, P〈0.05 or P〈0.01] 24 h after PCI in group A. Compared to before PCI, there were significant changes of vWF, Ⅷ:Ag, ATⅢ, GMP140, protein C, F.Ⅱa, Fbg, PAI, D-Dimer 20 min, 24 h, 7 d after PCI in group B[(135±37)%,(128±33)%,(88±19)% vs (70±18)%;(120±30),(99±24),(88±22)% vs (77±20)%; (157±34),(161±31),(164±33)mg/L vs (187±33)mg/L;(23±7),(22±6),(20±4)μg/L vs (17±4)μg/L;(2.2±1.1),(2.2±0.7),(2.5±0.8)mg/L vs (3.0±1.1)mg/L;(0.79±0.19),(0.74±0.18),(0.69±0.16)kU/L vs (0.61±0.16)kU/L;(6.6±1.7),(6.4±1.8),(6.1±1.7)g/L vs (5.2±1.2)g/L;(0.68±0.15),(0.66±0.15),(0.57±0.18)kAU/L vs (0.47±0.15)kAU/L; (1.22±0.34),(1.10±0.30),(0.94±0.22)mg/L vs (0.68±0.18)mg/L; P〈0.05 or P〈0.01]. Conclusions There are significant changes molecular markers of pre-thrombotic state in CHD patients after PCI, particularly among the patients complicated with HBP. There is a significant pre-thrombotic state in CHD patients after PCI, which might be promoted by HBP.
