    • Objective To evaluate efficacy and safety outcomes in patients in the PLATelet inhibition and patient Outcomes (PLATO) trial who at randomisation were planned for a non-invasive treatment strategy. Design Pre-specified analysis of pre-randomisation defined subgroup of prospective randomised clinical trial. Setting 862 centres in 43 countries. Participants 5216 (28%) of 18 624 patients admitted to hospital for acute coronary syndrome who were specified as planned for non-invasive management. Interventions Randomised treatment with ticagrelor (n=2601) versus clopidogrel (2615). Main outcome measurements Primary composite end point of cardiovascular death, myocardial infarction, and stroke; their individual components; and PLATO defined major bleeding during one year. Results 2183 (41.9%) patients had coronary angiography during their initial hospital admission, 1065 (20.4%) had percutaneous coronary intervention, and 208 (4.0%) had coronary artery bypass surgery. Cumulatively, 3143 (60.3%) patients had been managed non-invasively by the end of follow-up. The incidence of the primary end point was lower with ticagrelor than with clopidogrel (12.0% (n=295) v 14.3% (346); hazard ratio 0.85, 95% confidence interval 0.73 to 1.00; P=0.04). Overall mortality was also lower (6.1% (147) v 8.2% (195); 0.75, 0.61 to 0.93; P=0.01). The incidence of total major bleeding (11.9% (272) v 10.3% (238); 1.17, 0.98 to 1.39; P=0.08) and non-coronary artery bypass grafting related major bleeding (4.0% (90) v 3.1% (71); 1.30, 0.95 to 1.77; P=0.10) was numerically higher with ticagrelor than with clopidogrel. Conclusions In patients with acute coronary syndrome initially intended for non-invasive management, the benefits of ticagrelor over clopidogrel were consistent with those from the overall PLATO results, indicating the broad benefits of P2Y12 inhibition with ticagrelor regardless of intended management strategy.

    • Background: New randomized, controlled trials have become available on oral P2Y(12)inhibitors in acute coronary syndrome. We aimed to evaluate current evidence comparing the efficacy and safety profile of prasugrel, ticagrelor, and clopidogrel in acute coronary syndrome by a meta-analysis of randomized controlled trials.Methods: We performed a network meta-analysis and direct pairwise comparison analysis of efficacy and safety outcomes from 12 randomized controlled trials including a total of 52 816 patients with acute coronary syndrome.Results: In comparison with clopidogrel, ticagrelor significantly reduced cardiovascular mortality (hazard ratio [HR], 0.82 [95% CI, 0.72-0.92]) and all-cause mortality (HR, 0.83 [95% CI, 0.75-0.92]), whereas there was no statistically significant mortality reduction with prasugrel (HR, 0.90 [95% CI, 0.80-1.01] and HR, 0.92 [95% CI, 0.84-1.02], respectively). In comparison with each other, there were no significant differences in mortality (HR prasugrel versus ticagrelor, 1.10 [95% CI, 0.94-1.29] and 1.12 [95% CI, 0.98-1.28]). In comparison with clopidogrel, prasugrel reduced myocardial infarction (HR, 0.81 [95% CI, 0.67-0.98]), whereas ticagrelor showed no risk reduction (HR, 0.97 [95% CI, 0.78-1.22]). Differences between prasugrel and ticagrelor were not statistically significant. Stent thrombosis risk was significantly reduced by both ticagrelor and prasugrel versus clopidogrel (28%-50% range of reduction). In comparison with clopidogrel, both prasugrel (HR, 1.26 [95% CI, 1.01-1.56]) and ticagrelor (HR, 1.27 [95% CI, 1.04-1.55]) significantly increased major bleeding. There were no significant differences between prasugrel and ticagrelor for all outcomes explored.Conclusions: Prasugrel and ticagrelor reduced ischemic events and increased bleeding in comparison with clopidogrel. A significant mortality reduction was observed with ticagrelor only. There was no efficacy and safety difference between prasugrel and ticagrelor.
