NMA suggests that DAPT with low-dose ASA and ticagrelor was superior to low-dose ASA monotherapy in reducing mortality (OR 0.52, 95% CrI 0.30–0.87; I2 = 14; high certainty, mixed evidence). et al. Benefits of dual antiplatelet therapy (DAPT) have not been well established in all CABG patients. , Fuster V These patients may introduce heterogeneity, and post-randomization subgroups may introduce bias. et al. , Mróz J , Jaffer I , Boyle RM , Altman DG Mauri L , Nicoloff DM. , Hu S. Gasparovic H The surface under the cumulative ranking curve results are not consistent with the NMA results for other outcomes. J.-D. Schwalm: Supervision; Writing—review & editing. et al. , Short MA Long term aspirin therapy in patients with coronary artery disease (CAD) has recognised efficacy in reducing the risk of death, myocardial infarction, and stroke (1) as well as preventing ischemic complications (2). www.covidence.org (December 2018, date last accessed). Corresponding author. , Connolly SJ , Abrams KR , Lindsay WG Major bleeding was higher for DAPT with low-dose ASA and prasugrel; an antiplatelet regimen that was never adopted in practice for CABG patients due to high rates of major bleeding when compared to low-dose ASA with clopidogrel [9, 62]. Recent Canadian Guidelines recommend the use of dual antiplatelet therapy for 1 year after coronary artery bypass grafting in patients with acute coronary syndrome, but … , Gottlieb S © 2020 American Medical Association. , Jneid H Al Jaaly E (2015) Dual antiplatelet therapy after coronary artery bypass grafting: Do we have a consensus ntegr Cardiol, 2015, doi: 10.15761/JIC.1000126 Volume 1(4): 90-93 of P2Y1 893T and 1622G were 3.5 and 30.6%, respectively and these candidate genes were … , Walesby R We assessed statistical heterogeneity within pairwise comparisons using the I2 statistic. What do you do with the antiplatelet agents in patients with drug eluting stents who then receive a mechanical valve? Reversed long saphenous vein is the most commonly used conduit despite the known early thrombotic failure and low long-term patency rate. Hutton B Acetylsalicylic acid (ASA) monotherapy is the standard of care after coronary artery bypass grafting (CABG), but the benefits of more intense antiplatelet therapy, specifically dual antiplatelet therapy (DAPT), require further exploration in CABG patients. Clopidogrel 75 mg daily should be prescribed if prasugrel or ticagrelor are not suitable. Puru Panchal: Data curation; Visualization; Writing—original draft. In the arterial revascularization trial, only 21% of patients undergoing CABG were discharged on DAPT [79]. For instance, the Cardiovascular Outcomes for People Using Anticoagulation Strategies trial evaluated the effects of ASA 100 mg once daily alone, rivaroxaban 5 mg twice daily alone and rivaroxaban 2.5 mg twice daily with ASA 100 mg once daily on MACE. , Simonet F. Brilakis ES We aim to compare the survival and safety outcomes of DAPT versus aspirin (ASA) within a 24h window after CABG. All the enrolled patients will stop oral antiplatelet drugs according to local protocol before the surgery. In addition, we imposed no language restrictions. 5.1 DAPT in patients treated with coronary artery bypass surgery for stable coronary artery disease 5.2 DAPT in patients treated with coronary artery bypass surgery for acute coronary syndrome 5.3 DAPT for prevention of graft occlusion 5.4 Gaps in evidence 6. July 2018 in our center, and patients who received dual antiplatelet therapy (DAPT) after surgery (n=121)were included in this study. , Becker RC Lower rates of SVG occlusion with DAPT are offset by a higher rate of major bleeding. , Cannon CP This potentially inflates the power when compared to aggregating a summary measure that accounts for multiple grafts within patient. , Neutze JM A retrospective analysis of 11 118 CABG patients revealed that graft PCI yielded worse outcomes than native-vessel PCI (mortality HR 1.30, 95% CI 1.18–1.42 and MI HR 1.61, 95% CI 1.43–1.82) [78]. Preoperative Ticagrelor administration leads to a higher risk of , Sensoz Y , Ahmadian HR Circulation. [Google Scholar] , Oxman AD , van Gilst WH Major bleeding was reported in 19 trials (Table 4, Fig. Unfortunately, included studies did not note which antifibrinolytic agents were used intraoperatively. Aspirin (ASA) monotherapy is the standard of care after CABG, to improve long-term major adverse cardiovascular events (MACE) and graft patency. , Glineur D , Eksioglu-Demiralp E We assumed a common heterogeneity variance (τ2 estimated using restricted maximum likelihood approach, across the different comparisons in the network).
