摘要 目的:比较高危非ST段抬高急性冠脉综合征(NSTE—ACS)冠脉介入治疗(PCI)术前早期应用和术前即刻应用替罗非班对PCI术后心肌损伤和血小板功能的影响,评价两种应用时机的优势。方法:160例预行PCI的高危NSTE—ACS患者随机分为PCI术前早期应用替罗非班组(治疗1组,冠脉造影前4~6h应用替罗非班)和PCI术前即刻应用替罗非班组(治疗2组,导丝通过冠脉病变后应用替罗非班)。测定PCI术前和术后血清肌钙蛋白I(cTnI)和肌酸激酶同工酶(CK—MB),测定入院后、冠脉造影前和PCI术后血小板聚集率,记录使用替罗非班治疗期间的出血并发症和血小板减少症的发生率。结果:治疗1组PCI术后48h内cTnI的峰值、累积释放值和阳性例数均显著低于治疗2组(P〈0.05);两组PCI术后48h内CK—MB的峰值、累积释放值和阳性例数比较差异均无显著性(P〉0.05)。应用替罗非班后,两组血小板聚集率均显著降低(P〈0.05),治疗1组冠脉造影前的血小板聚集率显著低于治疗2组(P〈0.05)。在使用替罗非班治疗期间,两组重度出血并发症发生率比较差异无显著性(P〉0.05),中度出血并发症和轻度血小板减少症发生率均为1.25%。结论:在阿司匹林、氯吡格雷抗血小板治疗的基础上,高危NSTE—ACS患者PCI术前早期应用替罗非班,能够更早强化抗血小板治疗效果,明显减少PCI术后微量心肌损伤。
