摘要

目的:双重抗血小板治疗是经皮冠状动脉介入治疗(PCI)的标准治疗方法。传统上,患者在PCI之前或期间吞下P2Y12抑制剂的负荷剂量。吞咽负荷剂量后达到充分血小板抑制的时间差异很大。咀嚼片剂可以更快地抑制血小板聚集。然而,该策略在稳定性缺血性心脏病或非st段抬高急性冠状动脉综合征(NSTE-ACS)患者中的应用数据不太可靠。方法:在这项单中心前瞻性试验中,112例P2Y12-naïve接受阿司匹林治疗的稳定型缺血性心脏病或NSTE-ACS患者,在冠状动脉造影后但PCI前接受替格瑞洛治疗,随机分为咀嚼组(n=55)和吞咽组(n=57),替格瑞洛负荷剂量(180 mg)。基线变量比较采用两样本t检验和适当的卡方/Fisher精确检验,α集为0.05。采用Wilcoxon秩和检验比较基线、1小时和4小时P2Y12反应单位(PRU)。然后患者接受标准替格瑞洛剂量。结果:排除后,咀嚼组和吞咽组在替格瑞洛加载剂量后基线、1小时和4小时的P2Y12 PRU分别为243 vs 256 (P=0.75)、143 vs 210 (P=0.09)和28 vs 25 (P=0.89)。在30天和1年的主要不良心脏事件(MACE)或大出血方面没有发现差异。结论:在稳定性缺血性心脏病或NSTE-ACS患者中,咀嚼而不是吞咽替格瑞洛可能导致1小时血小板聚集的抑制略快,而MACE或大出血未增加。

Chewed Versus Swallowed Ticagrelor in P2Y12 Inhibitor-Naïve Patients Undergoing Percutaneous Coronary Intervention.

Purpose: Dual antiplatelet therapy is standard for patients undergoing percutaneous coronary intervention (PCI) with stents. Traditionally, patients swallow the loading dose of a P2Y12 inhibitor before or during PCI. Time to achieve adequate platelet inhibition after swallowing the loading dose varies significantly. Chewed tablets may allow more rapid inhibition of platelet aggregation. However, data for this strategy in patients with stable ischemic heart disease or non-ST-elevation acute coronary syndrome (NSTE-ACS) are less robust.

Methods: In this single-center prospective trial, 112 P2Y12-naïve patients with stable ischemic heart disease or NSTE-ACS on aspirin therapy and who received ticagrelor after coronary angiography but before PCI were randomized to chewing (n=55) or swallowing (n=57) the ticagrelor loading dose (180 mg). Baseline variables were compared using 2-sample t-test and chi-squared/Fisher's exact tests as appropriate, with alpha set at 0.05. P2Y12 reaction units (PRU) were compared at baseline, 1 hour, and 4 hours using Wilcoxon rank-sum test. Patients then received standard ticagrelor dosing.

Results: After exclusions, P2Y12 PRU in the chewed and swallowed groups at baseline, 1 hour, and 4 hours after ticagrelor loading dose were 243 vs 256 (P=0.75), 143 vs 210 (P=0.09), and 28 vs 25 (P=0.89), respectively. No differences were found in major adverse cardiac events (MACE) or major bleeding at 30 days and 1 year.

Conclusions: In patients with stable ischemic heart disease or NSTE-ACS, chewing rather than swallowing ticagrelor may lead to slightly faster inhibition of platelet aggregation at 1 hour with no increase in MACE or major bleeding.
