Abstract

Background

The transition from ticagrelor to clopidogrel is not based on pharmacodynamic or clinical studies, but it is a common practice. The aim of the present study was to test, in an exploratory way, the transition to two different doses of clopidogrel at the time of hospital discharge in patients diagnosed with acute coronary syndrome submitted to percutaneous coronary intervention who were initially treated with ticagrelor.

Methods

Patients previously treated with ticagrelor were randomized to receive a loading dose of 300 mg clopidogrel at hospital discharge, or 75 mg without the loading dose. The primary endpoint was the incidence of cardiovascular adverse events or bleeding at 30 days.

Results

Of 348 selected patients, 132 were enrolled and completed the study. The incidence of ischemic and hemorrhagic events at 30 days was similar between the groups, resulting in a rate of cardiac and cerebrovascular events of 6.1% vs. 9.1% (RR: 0.787; 95% CI: 0.361-1.715; p = 0.74).

Conclusions

The transition to clopidogrel with a dose of 75 mg at discharge, without a loading dose, appears to be a possible strategy. Studies with greater statistical power are needed to confirm these findings.

Introdução

A transição do ticagrelor para o clopidogrel não está fundamentada em estudos farmacodinâmicos ou clínicos, mas é uma prática comum. O objetivo do presente estudo foi testar, de forma exploratória, em pacientes com diagnóstico de síndrome coronariana aguda submetidos à intervenção coronariana percutânea, inicialmente tratados com ticagrelor, a transição para duas diferentes doses de clopidogrel no momento da alta hospitalar.

Métodos

Pacientes previamente tratados com ticagrelor foram randomizados para receber uma dose de ataque de 300 mg de clopidogrel no momento da alta hospitalar, ou 75 mg, omitindo-se a dose de ataque. O objetivo primário foi a incidência de eventos adversos cardiovasculares ou sangramento aos 30 dias.

Resultados

Dentre 348 pacientes selecionados, 132 foram incluídos e completaram o estudo. A incidência de eventos isquêmicos e hemorrágicos aos 30 dias foi similar entre os grupos, traduzindo-se em uma taxa de eventos cardíacos e cerebrovasculares de 6,1% vs. 9,1% (RR: 0,787; IC 95%: 0,361-1,715; p = 0,74).

Conclusões

A transição para clopidogrel com a dose de 75 mg no momento da alta, omitindo-se uma dose de ataque, aparenta ser uma estratégia possível. Estudos com maior poder estatístico são necessários para confirmar estes achados.

接受经皮冠状动脉介入治疗的急性冠状动脉综合征患者出院时替卡格雷和两种不同剂量氯吡格雷的转换
背景替卡格雷向氯吡格雷的过渡不是基于药效学或临床研究,而是一种常见的做法。本研究的目的是以探索性的方式测试最初接受替卡格雷治疗的诊断为急性冠状动脉综合征并接受经皮冠状动脉介入治疗的患者出院时向两种不同剂量氯吡格雷的过渡。方法既往接受替格瑞洛治疗的患者在出院时随机接受300mg氯吡格雷负荷剂量,或75mg无负荷剂量。主要终点是30天时心血管不良事件或出血的发生率。结果在348例入选患者中,132例参与并完成了研究。两组在30天时缺血性和出血事件的发生率相似,导致心脑血管事件发生率分别为6.1%和9.1%(RR:0.87,95%CI:0.361-1.715;p=0.74)。需要具有更大统计能力的研究来证实这些发现。引言替卡格雷向氯吡格雷的过渡不是基于药效学或临床研究,而是常见的做法。本研究的目的是在接受经皮冠状动脉介入治疗的急性冠状动脉综合征患者中进行探索性测试,这些患者最初接受替卡格雷治疗,出院时过渡到两种不同剂量的氯吡格雷。方法将既往接受替卡格雷治疗的患者随机分组,在出院时接受300mg氯吡格雷负荷剂量,或75mg,省略负荷剂量。主要终点是30天时心血管不良事件或出血的发生率。结果在选择的348名患者中,132人被纳入并完成了研究。两组在30天时缺血性和出血事件的发生率相似,导致心脑血管事件发生率分别为6.1%和9.1%(RR:0.87,95%CI:0.361-1.715;p=0.74)。需要具有更大统计能力的研究来证实这些发现。
