- Patients with acute coronary syndrome (ACS) are at risk for recurrent adverse events, and multiple reports suggest that this risk is increased in patients with concomitant diabetes mellitus (DM) and peripheral artery disease (PAD). The aim of this article was to investigate cardiovascular outcomes in patients with DM presenting with ACS, stratified by PAD status. Data were derived from 4 randomized post-ACS trials (PLATO [Platelet Inhibition and Patient Outcomes], APPRAISE-2 p Apixaban for Prevention of Acute Ischemic Events 2], TRILOGY [Targeted Platelet Inhibition to Clarify the Optimal Strategy to Medically Manage], and TRACER [Thrombin Receptor Agonist for Clinical Event Reduction in Acute Coronary Syndrome]). Using Cox regression analysis, we investigated major adverse cardiovascular events (MACEs), a composite of cardiovascular mortality, myocardial infarction (MI), or stroke and the individual components of MACE and all-cause mortality in patients with DM, presenting with ACS, stratified by PAD status as the risk modifier. This study included 15,387 patients with a diagnosis of DM and ACS, of whom 1,751 had an additional diagnosis of PAD. PAD was associated with more than doubled rates of MACE (hazard ratio [HR] 2.03, 95% confidence interval [CI] 1.81 to 2.27), all-cause mortality (HR 2.48, 95% CI 2.14 to 2.87), cardiovascular mortality (HR 2.42, 95% CI 2.04 to 2.86), and MI (HR 2.07, 95% CI 1.79 to 2.38). Patients with both PAD and DM were also more optimally treated with antihypertensive, antidiabetic, and statin medication at baseline. In conclusion, this analysis of 4 major post-ACS trials showed that patients with DM and PAD had a substantially higher risk of MACE, cardiovascular mortality, all-cause mortality, and MI despite being optimally treated with guideline-based therapies.

- BACKGROUND The long-term prognostic impact of post-discharge bleeding in the unique population of patients with acute coronary syndrome (ACS) treated without percutaneous coronary intervention (PCI) remains unexplored.OBJECTIVES The aim of this study was to assess the association between post-discharge bleeding and subsequent mortality after ACS according to index strategy (PCI or no PCI) and to contrast with the association between post-discharge myocardial infarction (MI) and subsequent mortality.METHODS In a harmonized dataset of 4 multicenter randomized trials (APPRAISE-2 [Apixaban for Prevention of Acute Ischemic Events-2], PLATO [Study of Platelet Inhibition and Patient Outcomes], TRACER [Thrombin Receptor Antagonist for Clinical Event Reduction in Acute Coronary Syndrome], and TRILOGY ACS [Platelet Inhibition to Clarify the Optimal Strategy to Medically Manage Acute Coronary Syndromes]), the association between post-discharge noncoronary artery bypass graft-related GUSTO (Global Use of Strategies to Open Occluded Coronary Arteries) moderate, severe, or life-threatening bleeding (landmark 7 days post-ACS) and subsequent all-cause mortality was evaluated in a time-updated Cox proportional hazards analysis. Interaction with index treatment strategy was assessed. Results were contrasted with risk for mortality following post-discharge MI.RESULTS Among 45,011 participants, 1,133 experienced post-discharge bleeding events (2.6 per 100 patient-years), and 2,149 died during follow-up. The risk for mortality was significantly higher <30 days (adjusted hazard ratio: 15.7; 95% confidence interval: 12.3 to 20.0) and 30 days to 12 months (adjusted hazard ratio: 2.7; 95% confidence interval: 2.1 to 3.4) after bleeding, and this association was consistent in participants treated with or without PCI for their index ACS (p for interaction = 0.240). The time-related association between post-discharge bleeding and mortality was similar to the association between MI and subsequent mortality in participants treated with and without PCI (p for interaction = 0.696).CONCLUSIONS Post-discharge bleeding after ACS is associated with a similar increase in subsequent all-cause mortality in participants treated with or without PCI and has an equivalent prognostic impact as post-discharge MI.

- 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.

- Intraocular bleeding is a devastating clinical event due to its potentially blinding nature. It is not known if determine if dual antiplatelet therapy using aspirin and potent P2Y12 inhibitors increases this risk. We searched MEDLINE and ClinicalTrials.gov for randomized controlled trials that were phase III, randomly assigned patients to dual antiplatelet therapy with either aspirin and a potent P2Y12 inhibitor or aspirin and clopidogrel, had follow-up of 6 months, and at least 200 patients. Corresponding authors were contacted for intraocular bleeding data. Inverse-variance, weighted, fixed-effects meta-analysis was undertaken, with random-effects meta-analysis performed as a sensitivity analysis. Four trials enrolling 42,850 patients were included. The median follow-up ranged from 12 to 14 months. There was overall low risk of bias. Pooled analysis demonstrated no statistically significant increase in the risk of intraocular bleeding with dual antiplatelet therapy using potent P2Y12 inhibitors compared with clopidogrel (risk ratio 0.89, 95% confidence interval 0.58 to 136). There was no significant heterogeneity observed across trials (I-2 statistic 0%, p = 0.98). The use of random-effects meta-analysis did not change the effect estimate or confidence intervals, and the results appeared similar when stratified by potent P2Y12 inhibitor (p = 0.97). In conclusion, this collaborative meta-analysis of dual antiplatelet trials does not suggest that the risk of intraocular bleeding is increased with the use of potent P2Y12 inhibitors compared with clopidogrel. Our results suggest that these potent P2Y12 inhibitors may continue to be used cautiously where indicated as part of dual antiplatelet therapy, even in those at high risk of spontaneous intraocular bleeding.
