Postgrad Med J: 低剂量替格瑞洛更适合东亚急性冠脉综合征患者!徐州学者Meta分析

2020-06-28 朱朱 中国循环杂志

对于急性冠脉综合征患者,目前的指南建议应用阿司匹林与替格瑞洛(90 mg,每日两次)或氯吡格雷(75 mg,每日一次)进行双联抗血小板治疗。

对于急性冠脉综合征患者,目前的指南建议应用阿司匹林与替格瑞洛(90 mg,每日两次)或氯吡格雷(75 mg,每日一次)进行双联抗血小板治疗。
 
既往研究表明,在冠脉介入治疗后的急性冠脉综合征患者中,与氯吡格雷相比,替格瑞洛可降低血管事件复发风险,但在临床实践中,尤其是在亚洲,替格瑞洛由于增加出血风险,其应用受限。
 
近日,江苏徐州医科大学研究人员发表的一项系统综述和Meta分析提示,在急性冠脉综合征患者中,与标准剂量氯吡格雷相比,低剂量替格瑞洛不仅可显著降低主要不良心血管事件发生风险,改善左室射血分数,降低左室舒张末期容积,同时不增加出血事件风险。
 
分析显示,与应用标准剂量氯吡格雷的患者相比,应用低剂量替格瑞洛的患者中主要不良心血管事件发生风险降低了61%。
 
两类患者中大出血风险相似,应用低剂量替格瑞洛的患者中小出血或微出血事件以及不良反应发生风险均明显降低。
 
另外,与标准剂量氯吡格雷相比,低剂量替格瑞洛可改善左室射血分数,降低左室舒张末期容积,显著降低血小板聚集率和血小板反应单位。
 
研究者认为,与标准剂量氯吡格雷相比,低剂量替格瑞洛安全性和有效性均较好,这对东亚患者来说会极大地改善服药依从性,因此低剂量替格瑞洛可能更适合东亚患者。
 
该分析共纳入16项相关随机对照研究、1629例急性冠脉综合征患者;其中756人应用低剂量替格瑞洛,其余873人应用标准剂量氯吡格雷;所有患者每日服用75~125 mg阿司匹林,不应用其他抗栓药物。他们来自全球,但主要来自韩国、希腊和中国。
 
在该研究中,低剂量替格瑞洛是指:90 mg每日一次(484人),45 mg每日两次(240人)或60 mg每日两次(32人)。

ACC 2020:PCI术后患者用3个月双抗后,单独使用替格瑞洛9个月可能更好(TICO研究)

近二十年来,急性冠脉综合征(ACS)患者的抗血小板药物治疗理念从单药抗血小板治疗(SAPT)发展到多靶点药物联合的双联抗血小板治疗(DAPT)。近年来,随着对患者个体化治疗认识的加深及对缺血-出血风险

Circulation:替格瑞洛用于急性冠脉综合征患者的安全性劣于氯吡格雷!

鉴于出血和缺血性事件对抗血小板治疗的反应不同,P2Y12抑制剂替格瑞洛(ticagrelor)在东亚人群中的安全性和有效性仍不明确。本研究是一个多中心的临床试验,在韩国招募了800位因急性冠脉综合征(有或无ST段抬高)住院、计划进行侵入性干预的患者,将患者按1:1随机分至替格瑞洛组(首剂 180mg,随后90mg 2/日)或氯吡格雷组(首剂 600mg,随后75mg/日)。主要安全结点是12个月内

替格瑞洛应联合50 mg阿司匹林?阜外医院颜红兵等研究称,出血风险更低,心血管事件未增加

中国医院科学院阜外医院颜红兵团队研究称,替格瑞洛联合极低剂量阿司匹林(50 mg)出血风险更低,且主要不良心血管事件(MACE)风险无显着差异。研究比较了替格瑞洛联合75-100 mg阿司匹林(n=744)和联合50 mg阿司匹林(n=322)的远期预后。研究纳入了1066例接受替格瑞洛(90 mg bid)+阿司匹林双联抗血小板治疗的患者,分为两个阿司匹林剂量组:75-100 mg(n=744)

JACC:替格瑞洛联合阿司匹林对PCI术后的抗血栓影响

本研究的目的旨在比较和评估替格瑞洛以及替格瑞洛联合乙酰水杨酸(ASA)对接受药物洗脱支架冠脉介入治疗患者的抗血栓形成效果。TWILIGHT临床试验将接受PCI治疗患者在3个月的双重抗血栓形成治疗中随机分成替格瑞洛+安慰剂治疗和替格瑞洛联合ASA治疗,主要终点事件是花生四烯酸刺激后的血栓大小。最终共纳入分析了51名患者,随访结束后的血栓面积在两组患者中无明显差异(p=0.22),在对环氧化酶-1阻断

JAMA:替格瑞洛单药vs替格瑞洛+阿司匹林对ACS支架患者不良临床事件的影响

对于接受药物洗脱支架治疗的ACS患者,在3个月的双重抗血小板治疗后转为替卡格雷单药治疗可降低大出血和心血管事件风险

加拿大研究称,与氯吡格雷相比,替格瑞洛致大出血风险增加51%

基于随机临床试验证据,目前指南建议,急性冠脉综合征患者应优选替格瑞洛,而非氯吡格雷。然而,近期有研究对此提出了质疑。1月13日,发表在JAMA内科学子刊上的一项来自加拿大的1.1万例患者研究提示,对于接受经皮冠脉介入治疗的急性冠脉综合征患者,与氯吡格雷相比,替格瑞洛并不能降低主要不良冠脉事件风险,相反还增加大出血和呼吸困难的发生风险。在该研究中,与应用氯吡格雷的患者相比,应用替格瑞洛的患者中1年主
