GPIIb/IIIa拮抗剂integrilin在经皮冠状动脉支架成形术围术期的运用

目的 :报告GPIIb/IIIa拮抗剂integrilin在经皮冠状动脉支架成形术围术期运用的方法和结果。方法 :9例接受经皮冠状动脉支架成形术患者动脉穿刺完成后即刻注入Integrilin 1 80 μg/kg ,然后按 2 μg/kg/min维持 ,维持时间为 1 2h ,联合应用阿司匹林、Plavix、肝素等其他抗凝和抗血小板药物。常规监测ACT、PT和KPTT ,出院前及术后 1月复查血细胞各 1次。结果 :全部患者均在术后 2 -4h拔除鞘管 ,无穿刺部位显著血肿形成者 ,无冠状动脉急性和亚急性血栓形成者。术后血小板无显著改变 ,术后 8例患者ACT在 2h内和 1例在 4h内恢复至≤ 1 50 ,KPTT在术后 2h与术前相比有显著性差异 ,PT和血小板记数术前、术后无显著性改变。术后随访 3-4月 ,无心绞痛症状复发者。结论 :GPIIb/IIIa拮抗剂integrilin在经皮冠状动脉支架成形术围术期运用 ,结合抗血小板药物Plavix和阿司匹林 ,能显著减少肝素用量和缩短运用时间 ,缩短血管鞘的留置时间 ,而未显示增加出血危险性 ,也未发生支架内血栓形成者。

Application of GlycoProtein IIb/IIIa antagonist( Integrilin) in peri-percutaneous transluminal catheter angioplasty and stent implantation in Chinese

Objective: to report the application of GPIIb/IIIa antagonist (Integrilin) in peri percutaneous transluminal catheter angioplasty and stent implantation in Chinese. Method: Twenty one patients who underwent percutaneous transluminal catheter angioplasty(PTCA) and stent implantation were included. After arterial puncture, integrilin was injected at dose of 180ug/kg, and then maintained at 2μg/kg·min for 18 hours. Asprine, plavix(clopidogrel) and heparin were used at the same time. ACT, PT, KPTT and blood routine were routinely monitored. Results: All sheaths were drawn out 2 to 4 hours after the procedure.. There was no severe complication such as hematoma, acute and subacute thrombosis in coronary artery, or thrombocytopenia. ACT returned to less than 150 seconds in 2 hours in 15 patients; in 4 hours in 6 patients. There was no significant difference between the pre and post procedure value of PT and platelet count. KPTT was significantly higher than pre procedure value at 2 hours after the procedure .No recurrence of angina pectoris was observed in the first nine patients within one year follow up, and no restenosis occurred in stents in the five patients who had coronary angiography one year later. Conclusion: Application of GPIIb/IIIa receptor antagonist (Integrilin) in peri percutaneous transluminal catheter angioplasty and stent implantation in combination with aspirin and plavix could significantly reduce the dosage and duration of heparin with benefit of shortening the indwelling time of sheaths, but did not increase risk of bleeding or lead to thrombosis in stent.

依替巴肽对急性心肌梗死患者血清可溶性致癌抑制因子2及血清五聚素3水平的影响

目的研究依替巴肽对行直接PCI的急性ST段抬高型心肌梗死(STEMI)患者血清可溶性致癌抑制因子2(sST2)和血清五聚素3(PTX3)水平的影响。方法选取我院确诊的急性STEMI患者96例,随机分为观察组(依替巴肽联合PCI)48例和对照组(PCI)48例。随访6个月,记录2组患者术后90min心电图ST段抬高总和回落(STR)>50%、心肌灌注3级和TIMI 3级血流比例;术前和术后1个月LVEF、左心室舒张末期内径(LVEDD)、血清sST2及PTX3水平;术后6个月内主要不良心脏事件(MACE)发生率,并进行比较。结果观察组术后心肌灌注3级比例高于对照组(97.9%vs 85.4%,χ2=4.909,P=0.027),STR>50%比例高于对照组(91.7%vs 70.8%,χ2=6.842,P=0.009);2组TIMI 3级血流比例比较,差异无统计学意义(P>0.05)。1个月时,2组LVEF均高于同组术前水平,LVEDD、血清sST2及PTX3水平均低于同组术前(P <0.05);且观察组LVEF高于对照组,LVEDD、血清sST2及PTX3低于对照组(P<0.05;P<0.01)。观察组术后6个月内MACE发生率低于对照组(8.3%vs 22.9%,χ2=3.872,P=0.049),2组均无死亡患者。结论急性STEMI患者PCI联用依替巴肽疗效良好,能改善心功能,降低血清sST2及PTX3水平和MACE发生率。
