  • 背景和目标

    建议采用常规侵入性策略来管理非ST段抬高型急性冠状动脉综合征(NSTE ACSs)的高危患者。然而,之前接受过冠状动脉旁路移植术(CABG)手术的患者被排除在为这些指南提供信息的关键试验之外。因此,在这个特定的亚组中,常规侵入性策略的益处不太确定。

    方法

    对随机对照试验(RCTs)进行了系统评价和荟萃分析。对PubMed、EMBASE、Cochrane和ClinicalTrials.gov进行了全面搜索。符合条件的研究是针对非ST段抬高型急性冠状动脉综合征患者(包括既往冠状动脉旁路移植术患者)的常规侵入性与保守或选择性侵入性策略的随机对照试验。如果之前没有发表过,则从每个试验的作者那里收集汇总数据。评估的结果为全因死亡率、心脏死亡率、心肌梗死和心脏相关住院。使用随机效应模型,计算了95%置信区间(CI)的风险比(RR)。

    结果

    总结数据来自11项随机对照试验,包括9项试验的先前未发表的亚组结果,包括897名既往冠状动脉旁路移植术患者(477名常规侵入性,420名保守/选择性侵入性),随访加权平均2.0年(范围0.5-10年)。常规侵入性策略并没有降低全因死亡率(RR 1.12,95%CI 0.97-1.29)、心脏死亡率(RR 1.05,95%CI 0.70-1.58)、心肌梗死(RR 0.90,95%CI0.65-1.23)或心脏相关住院率(RR 1.05,95%CI 0.758-1.40)。

    结论

    这是首次荟萃分析,评估了常规侵入性策略对患有非ST段抬高型心肌梗死的既往冠状动脉旁路移植术患者的影响。结果证实,该患者组在非ST段抬高型急性冠状动脉综合征侵入性治疗的随机对照试验中代表性不足,并表明与保守治疗相比,常规侵入性策略在重大不良心脏事件方面没有益处。这些发现应在一个有足够能力的随机对照试验中得到验证。

    • 冠状动脉旁路移植手术(CABG)后给予长期阿司匹林预防大隐静脉移植物闭塞并减少心血管不良事件的发生率。 有人认为加入有效的P2Y12受体阻断剂如替格瑞洛可能会进一步改善预后。 在DACAB试验中,接受CABG的500名患者在术后24小时内被随机分配为替格瑞洛加阿司匹林,单用替格瑞洛或单用阿司匹林。 通过心血管成像确定的主要终点,一年的隐静脉移植通畅分别发生在三组静脉移植物中约89%,83%和77%。 虽然替卡格雷与阿司匹林的添加统计学上比单独使用阿司匹林更有效,但我们不推荐使用它,并担心增加出血风险的可能性,并等待临床结果的临床试验结果。 Importance The effect of ticagrelor with or without aspirin on saphenous vein graft patency in patients undergoing coronary artery bypass grafting (CABG) is unknown. Objective To compare the effect of ticagrelor + aspirin or ticagrelor alone vs aspirin alone on saphenous vein graft patency 1 year after CABG. Design, Setting, and Participants Randomized, multicenter, open-label, clinical trial among 6 tertiary hospitals in China. Eligible patients were aged 18 to 80 years with indications for elective CABG. Patients requiring urgent revascularization, concomitant cardiac surgery, dual antiplatelet or vitamin K antagonist therapy post-CABG, and who were at risk of serious bleeding were excluded. From July 2014 until November 2015, 1256 patients were identified and 500 were enrolled. Follow-up was completed in January 2017. Interventions Patients were randomized (1:1:1) to start ticagrelor (90 mg twice daily) + aspirin (100 mg once daily) (n = 168), ticagrelor (90 mg twice daily) (n = 166), or aspirin (100 mg once daily) (n = 166) within 24 hours post-CABG. Neither patients nor treating physicians were blinded to allocation. Main Outcomes and Measures Primary outcome was saphenous vein graft patency 1 year after CABG (FitzGibbon grade A) adjudicated independently by a committee blinded to allocation. Saphenous vein graft patency was assessed by multislice computed tomographic angiography or coronary angiography. Results Among 500 randomized patients (mean age, 63.6 years; women, 91 [18.2%]), 461 (92.2%) completed the trial. Saphenous vein graft patency rates 1 year post-CABG were 88.7% (432 of 487 vein grafts) with ticagrelor + aspirin; 82.8% (404 of 488 vein grafts) with ticagrelor alone; and 76.5% (371 of 485 vein grafts) with aspirin alone. The difference between ticagrelor + aspirin vs aspirin alone was statistically significant (12.2% [95% CI, 5.2% to 19.2%]; P < .001), whereas the difference between ticagrelor alone vs aspirin alone was not statistically significant (6.3% [95% CI, -1.1% to 13.7%]; P = .10). Five major bleeding episodes occurred during 1 year of follow-up (3 with ticagrelor + aspirin; 2 with ticagrelor alone). Conclusions and Relevance Among patients undergoing elective CABG with saphenous vein grafting, ticagrelor + aspirin significantly increased graft patency after 1 year vs aspirin alone; there was no significant difference between ticagrelor alone and aspirin alone. Further research with more patients is needed to assess comparative bleeding risks.Trial Registration clinicaltrials.gov Identifier: NCT02201771.
