To compare the effect of ticagrelor with clopidogrel in reducing the risk of ischemic cardiovascular events in patients with late or very late stent thrombosis (LST/VLST) after primary percutaneous coronary intervention (PCI).
A total of 4538 patients with acute coronary syndrome were screened for angiographically determined LST/VLST. Two hundred and forty-one patients were included in the analysis and grouped according to ticagrelor (n = 81) or clopidogrel (n = 160) at discharge. The clinical outcome was major adverse cardiovascular events (MACE) defined as death, myocardial infarction (MI), ischemic stroke, and revascularization during the 1-yr follow-up period.
After propensity score matching, 65 pairs were generated. The incidence of MACE was significantly lower in the ticagrelor group compared with the clopidogrel group (9.3% vs. 21.5%, log-rank p = 0.048). However, no difference was observed in event rates of death, MI, ischemic stroke, and revascularization between the ticagrelor group and the clopidogrel group.
Following successful primary PCI, patients with LST/VLST who received ticagrelor had fewer ischemic cardiovascular events at 1-yr follow-up, compared with those who received clopidogrel.
比较替格瑞洛与氯吡格雷在降低经皮冠状动脉介入治疗(PCI)后迟发或极晚期支架血栓形成(LST/VLST)患者缺血性心血管事件风险方面的效果。
共筛选出 4538 例急性冠脉综合征患者,进行血管造影确定的 LST/VLST。241 例患者纳入分析,并根据出院时替格瑞洛(n=81)或氯吡格雷(n=160)分组。主要不良心血管事件(MACE)定义为 1 年随访期间的死亡、心肌梗死(MI)、缺血性卒中和血运重建。
经倾向评分匹配后,生成 65 对。与氯吡格雷组相比,替格瑞洛组的 MACE 发生率显著降低(9.3% vs. 21.5%,对数秩检验 p=0.048)。然而,替格瑞洛组与氯吡格雷组之间的死亡率、MI、缺血性卒中和血运重建的事件发生率无差异。
在成功进行经皮冠状动脉介入治疗后,与接受氯吡格雷治疗的患者相比,接受替格瑞洛治疗的 LST/VLST 患者在 1 年随访时发生缺血性心血管事件的风险更低。
