摘 要:目的 观察中高危非ST段抬高急性冠脉综合征(NSTACS)患者经皮冠状动脉介入治疗(PCI)术前应用替罗非班的影响。方法 入选2009年5月至2010年7月在北京安贞医院心内科住院拟行PCI的中高危NSTACS患者(不稳定型心绞痛或急性非ST段抬高型心肌梗死)80例,年龄18~75岁。术前组(38例):患者在造影前(12±2)h开始首先给予10μg/kg负荷量的替罗非班,3 min内推注完毕,然后以0.15μg/kg/min静滴至PCI完成后24 h;术中组(42例):在指引导管到位后给予10μg/kg的负荷剂量,3 min内推注完毕,然后改为0.15μg/kg/min静滴至PCI完成后24 h。比较两组院内、30 d内主要不良心血管事件发生情况。术前和术后检测高敏C反应蛋白(hs-CRP)和可溶性CD40配体(s CD40L)、肌钙蛋白I(TNI)和肌酸激酶同工酶(CK-MB)。结果 与本组术前比较,术前组在PCI术后CK-MB、hsCRP和s CDL40降低,为(22.91±11.76)U/L vs.(14.69±15.72)U/L、(16.50±7.76)mg/L vs.(10.91±13.16)mg/L、(18.92±8.90)μg/L vs.(12.65±10.99)μg/L,差异有统计学意义(P均〈0.05)。与术中组比较,术前组在PCI术后s CDL40降低[(14.23±8.91)μg/L vs.(12.65±10.99)μg/L],差异有统计学意义(P〈0.05)。两组终点事件发生率比较,无统计学意义(P=0.860)。结论 早期PCI术前应用替罗非班能抑制炎症反应,明显减少心肌的急性损害。Objective To observe the influence of preoperative tirofiban administration on the inflammatory reactions in patients with middle-high risk of non-ST-segment elevation acute coronary system (NSTEACS). Methods The patients (n=80 and aged from 18 to 75) planed to have percutaneous coronary intervention (PCI) were chosen from May 2009 to Jul. 2010, and divided into 2 groups. The pre-PCI group (n=38) was given tirofiban in loading dose (10 g/kg injected within 3 min) at first and (12±2) h before coronary angiography and then given intravenous drip of tirofiban (0.15 g/kg/min) for 24 h after PCI. The control group (n=42) was given tirofiban in loading dose (10 g/kg injected within 3 min) after guiding catheter placed and then given intravenous drip of tirofiban (0.15 g/kg/min) for 24 h after PCI. The incidence of major adverse cardiovascular events (MACE) was compared between 2 group during hospital stay and 30 d after discharge. The levels of high-sensitivity C-reactive protein (hs-CRP), soluble CD40 ligand (sCD40L), cardiac troponin I (cTnI) and creatine kinase MB (CK-MB) were detected befor and after PCI. Results In pre-PCI group, the levels of CK-MB, hs-CRP and sCDL40 decreased after PCI [(22.91±11.76) U/L vs. (14.69±15.72) U/L], [(16.50±7.76) mg/L vs. (10.91±13.16) mg/L], [(18.92± 8.90) g/L vs. (12.65±10.99) g/L, all P〈0.05]. Compared with control group, sCDL40 decreased in pre-PCI group after PCI [(14.23±8.91) g/L vs. (12.65±10.99) g/L, P〈0.05]. The difference in incidence of endpoint events had no statistical significance (P=0.860) between 2 groups. Conclusion The early administration of tirofiban before PCI can inhibit the inflammatory reactions and relieve acute myocardial impairment.
