- 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.

- IMPORTANCE: In patients with multivessel coronary artery disease (CAD) presenting with ST-segment elevation myocardial infarction (STEMI), complete revascularization reduces major cardiovascular events compared with culprit lesion-only percutaneous coronary intervention (PCI). Whether complete revascularization also improves angina-related health status is unknown.OBJECTIVE: To determine whether complete revascularization improves angina status in patients with STEMI and multivessel CAD.DESIGN, SETTING, AND PARTICIPANTS: This secondary analysis of a randomized, multinational, open label trial of patient-reported outcomes took place in 140 primary PCI centers in 31 countries. Patients presenting with STEMI and multivessel CAD were randomized between February 1, 2013, and March 6, 2017. Analysis took place between July 2021 and December 2021.INTERVENTIONS: Following PCI of the culprit lesion, patients with STEMI and multivessel CAD were randomized to receive either complete revascularization with additional PCI of angiographically significant nonculprit lesions or to no further revascularization.MAIN OUTCOMES AND MEASURES: Seattle Angina Questionnaire Angina Frequency (SAQ-AF) score (range, 0 [daily angina] to 100 [no angina]) and the proportion of angina-free individuals by study end.RESULTS: Of 4041 patients, 2016 were randomized to complete revascularization and 2025 to culprit lesion-only PCI. The mean (SD) age of patients was 62 (10.7) years, and 3225 (80%) were male. The mean (SD) SAQ-AF score increased from 87.1 (17.8) points at baseline to 97.1 (9.7) points at a median follow-up of 3 years in the complete revascularization group (score change, 9.9 [95% CI, 9.0-10.8]; P < .001) compared with an increase of 87.2 (18.4) to 96.3 (10.9) points (score change, 8.9 [95% CI, 8.0-9.8]; P < .001) in the culprit lesion-only group (between-group difference, 0.97 points [95% CI, 0.27-1.67]; P = .006). Overall, 1457 patients (87.5%) were free of angina (SAQ-AF score, 100) in the complete revascularization group compared with 1376 patients (84.3%) in the culprit lesion-only group (absolute difference, 3.2% [95% CI, 0.7%-5.7%]; P = .01). This benefit was observed mainly in patients with nonculprit lesion stenosis severity of 80% or more (absolute difference, 4.7%; interaction P = .02).CONCLUSIONS AND RELEVANCE: In patients with STEMI and multivessel CAD, complete revascularization resulted in a slightly greater proportion of patients being angina-free compared with a culprit lesion-only strategy. This modest incremental improvement in health status is in addition to the established benefit of complete revascularization in reducing cardiovascular events.

- Background and Objective In patients with atrial fibrillation following percutaneous coronary intervention, if a proton pump inhibitor is used, could that allow the use of warfarin triple therapy, or is there additional reduction in bleeding while using it with dual therapy? Methods The RE-DUAL PCI trial randomized 2725 patients with atrial fibrillation post-percutaneous coronary intervention to dabigatran dual therapy (110 or 150 mg twice daily, with clopidogrel or ticagrelor) or warfarin triple therapy (with clopidogrel or ticagrelor, and aspirin for 1-3 months). This prespecified subgroup analysis evaluated risks of a first major bleeding event or clinically relevant non-major bleeding event, all gastrointestinal bleeding, and a composite efficacy endpoint of all-cause mortality/thromboembolic event or unplanned revascularization according to baseline use of a proton pump inhibitor. Results Of 2678 analyzed patients, 1641 (61.3%) were receiving a proton pump inhibitor at baseline. Dabigatran 110 and 150 mg dual therapy reduced the risk of major bleeding events or clinically relevant non-major bleeding events vs warfarin triple therapy regardless of proton pump inhibitor use, with comparable risk of the composite efficacy endpoint (all interactionpvalues > 0.05). For gastrointestinal bleeding, no interaction was observed between study treatment and proton pump inhibitor use (interactionpvalues 0.84 and 0.62 for dabigatran 110 and 150 mg dual therapy, respectively, vs warfarin triple therapy). Conclusions Dabigatran 110 and 150 mg dual therapy reduced the risk of major bleeding events or clinically relevant non-major bleeding events vs warfarin triple therapy, regardless of proton pump inhibitor use at baseline, in patients with atrial fibrillation who underwent percutaneous coronary intervention. Risk of the composite efficacy endpoint appeared to be similar for dabigatran dual therapy vs warfarin triple therapy in patients receiving/not receiving a proton pump inhibitor.

- AimsAfter percutaneous coronary intervention (PCI) in patients with atrial fibrillation, safety and efficacy with dabigatran dual therapy were evaluated in pre-specified subgroups of patients undergoing PCI due to acute coronary syndrome (ACS) or elective PCI, and those receiving ticagrelor or clopidogrel treatment.Methods and resultsIn the RE-DUAL PCI trial, 2725 patients were randomized to dabigatran 110 mg or 150 mg with P2Y12 inhibitor, or warfarin with P2Y12 inhibitor and aspirin. Mean follow-up was 14 months, 50.5% had ACS, and 12% received ticagrelor. The risk of the primary endpoint, major or clinically relevant non-major bleeding event, was reduced with both dabigatran dual therapies vs. warfarin triple therapy in patients with ACS [hazard ratio (95% confidence interval), 0.47 (0.35-0.63) for 110 mg and 0.67 (0.50-0.90) for 150 mg]; elective PCI [0.57 (0.43-0.76) for 110 mg and 0.76 (0.56-1.03) for 150 mg]; receiving ticagrelor [0.46 (0.28-0.76) for 110 mg and 0.59 (0.34-1.04) for 150 mg]; or clopidogrel [0.51 (0.41-0.64) for 110 mg and 0.73 (0.58-0.91) for 150 mg], all interaction P-values >0.10. Overall, dabigatran dual therapy was comparable to warfarin triple therapy for the composite endpoint of death, myocardial infarction, stroke, systemic embolism, or unplanned revascularization, with minor variations across the subgroups, all interaction P-values >0.10.ConclusionThe benefits of both dabigatran 110 mg and 150 mg dual therapy compared with warfarin triple therapy in reducing bleeding risks were consistent across subgroups of patients with or without ACS, and patients treated with ticagrelor or clopidogrel.

- Background: Guidelines suggest that "upstream" P2Y(12) receptor antagonists should be considered in patients with non-ST-segment elevation acute coronary syndromes (NSTE-ACS).Hypothesis: Early use of ticagrelor in patients managed with an invasive strategy would be more effective than clopidogrel because of its more rapid onset of action and greater potency.Methods: In the PLATO trial, 6792 NSTE-ACS patients were randomized to ticagrelor or clopidogrel (started prior to angiography) and underwent angiography within 72 hours of randomization. We compared efficacy and safety outcomes of ticagrelor vs clopidogrel as a function of "early" (<3h) vs "late" (>= 3h) time to angiography. Adjusted Cox proportional hazards models evaluated interaction between randomized treatment and time from randomization to angiography on subsequent outcomes.Results: Overall, a benefit of ticagrelor vs clopidogrel for cardiovascular death/myocardial infarction/stroke was seen at day 7 (hazard ratio [HR]: 0.67, P = 0.002), day 30 (HR: 0.81, P = 0.042), and 1 year (HR: 0.80, P = 0.0045). There were no significant interactions in the <3h vs >= 3h groups at any timepoint. For major bleeding, overall there was no significant increase (HR: 1.04, 95% confidence interval: 0.85-1.27); but there was a significant interaction with no difference between ticagrelor and clopidogrel in the early group (HR: 0.79), but higher bleeding risk with ticagrelor in the late angiography group, at 7 days (HR: 1.51, P-int = 0.002). Patterns were similar at 30 days and 1 year.Conclusions: The benefit of ticagrelor over clopidogrel was consistent in those undergoing early and late angiography, supporting upstream use of ticagrelor

- Dual antiplatelet therapy (DAPT), the combination of aspirin and a P2Y12 inhibitor, given for 12 months remains the standard of care after presentation with acute coronary syndrome (ACS) because it has been shown to be associated with a significant reduction in ischemic events compared with aspirin monotherapy. The factor Xa inhibitor rivaroxaban was shown to be associated with a significant reduction in the composite of cardiovascular death, myocardial infarction, and stroke, and resulted in a nominal reduction in cardiovascular death, when added to background DAPT in the ATLAS ACS 2-TIMI 51 trial; however, there was excessive bleeding with this "triple-therapy" approach. The combination of rivaroxaban with P2Y12 inhibition in a "dual-pathway" approach may be an effective therapeutic regimen for the treatment of ACS, given the known importance of P2Y12 inhibition after stenting and intriguing data that the combination of an anticoagulant with clopidogrel after stenting in patients with atrial fibrillation appears an attractive option to this patient population. GEMINI-ACS-1 is a prospective, randomized, double-dummy, double-blind, active-controlled trial that will assess the safety of dual antithrombotic therapy (rivaroxaban [2.5 mg twice daily] + P2Y12 inhibitor) as compared with DAPT (aspirin [100 mg] + P2Y12 inhibitor) within 10 days of an ACS event in 3,000 patients. Patients will be randomized in a 1: 1 ratio stratified by intended P2Y12 inhibitor use (clopidogrel 75 mg daily or ticagrelor 90 mg twice daily), with 1500 patients expected in each P2Y12 inhibitor strata. The primary end point is Thrombolysis in Myocardial Infarction clinically significant bleeding (major, minor, or requiring medical attention). The exploratory efficacy determination will be a composite of cardiovascular death, myocardial infarction, ischemic stroke, and stent thrombosis. GEMINI-ACS-1 will assess the safety and feasibility of dual antithrombotic therapy with rivaroxaban and a P2Y12 inhibitor compared with conventional DAPT for the treatment for patients with recent ACS.

- OBJECTIVE: In observational data, lower levels of lipoprotein(a) have been associated with greater prevalence of type 2 diabetes. Whether pharmacologic lowering of lipoprotein(a) influences incident type 2 diabetes is unknown. We determined the relationship of lipoprotein(a) concentration with incident type 2 diabetes and effects of treatment with alirocumab, a PCSK9 inhibitor.RESEARCH DESIGN AND METHODS: In the ODYSSEY OUTCOMES trial alirocumab was compared with placebo in patients with acute coronary syndrome. Incident diabetes was determined from laboratory, medication, and adverse event data.RESULTS: Among 13,480 patients without diabetes at baseline, 1,324 developed type 2 diabetes over a median 2.7 years. Median baseline lipoprotein(a) was 21.9 mg/dL. With placebo, 10 mg/dL lower baseline lipoprotein(a) was associated with hazard ratio 1.04 (95% CI 1.02-1.06, P < 0.001) for incident type 2 diabetes. Alirocumab reduced lipoprotein(a) by a median 23.2% with greater absolute reductions from higher baseline levels and no overall effect on incident type 2 diabetes (hazard ratio 0.95, 95% CI 0.85-1.05). At low baseline lipoprotein(a) levels, alirocumab tended to reduce incident type 2 diabetes, while at high baseline lipoprotein(a) alirocumab tended to increase incident type 2 diabetes compared with placebo (treatment-baseline lipoprotein(a) interaction P = 0.006). In the alirocumab group, a 10 mg/dL decrease in lipoprotein(a) from baseline was associated with hazard ratio 1.07 (95% CI 1.03-1.12; P = 0.0002) for incident type 2 diabetes.CONCLUSIONS: In patients with acute coronary syndrome, baseline lipoprotein(a) concentration associated inversely with incident type 2 diabetes. Alirocumab had neutral overall effect on incident type 2 diabetes. However, treatment-related reductions in lipoprotein(a), more pronounced from high baseline levels, were associated with increased risk of incident type 2 diabetes. Whether these findings pertain to other therapies that reduce lipoprotein(a) is undetermined.

- Background: Although bradyarrhythmias have been observed with ticagrelor and its use with advanced atrioventricular block is not recommended, questions arise regarding its use in patients with mild conduction abnormalities. The objectives were to compare rates of clinically relevant arrhythmias in relation to any mild baseline conduction abnormality in patients with acute coronary syndrome randomized to ticagrelor versus clopidogrel. Methods: We included all subjects in the electrocardiographic (ECG) substudy of the Platelet Inhibition and Patient Outcomes trial, excluding those with missing baseline ECG or with a pacemaker at baseline (N = 15,460). Conduction abnormality was defined as sinus bradycardia, first-degree atrioventricular block, hemiblock, or bundle-branch block. The primary arrhythmic outcome was the composite of any symptomatic brady-or tachyarrhythmia, permanent pacemaker placement, or cardiac arrest through 12 months. Results: Patients with baseline conduction abnormalities (n = 4,256, 27.5%) were older and more likely to experience the primary arrhythmic outcome. There were no differences by ticagrelor versus clopidogrel in the composite arrhythmic end point in those with baseline conduction disease (1-year cumulative incidence rate: 17% for both study arms; hazard ratio: 0.99 [0.86-1.15]) or without baseline conduction disease (1-year cumulative incidence rate: clopidogrel 12.8% vs ticagrelor 12.4%; hazard ratio: 0.98 (0.88-1.09). There were also no statistically significant differences between ticagrelor and clopidogrel in the rates of bradycardic (or any individual arrhythmic) events in patients with baseline conduction abnormalities. Conclusions: Ticagrelor compared to clopidogrel did not increase arrhythmic events even in subjects with acute coronary syndrome who present with mild conduction abnormalities on their baseline ECG.
