Aim      To evaluate outcomes in patients with acute coronary syndrome and atrial fibrillation who receive rivaroxaban and the patients’ compliance with the antithrombotic therapy.Material and methods  The study was performed from October 2017 through December 2019 and included 129 patients. Events between the discharge from the hospital and 12 months of follow-up were recorded. The primary endpoint was development of major, minor or requiring medical attention bleeding according to the TIMI scale. The secondary endpoint was a combination of recurrent myocardial infarction, nonfatal acute ischemic cerebrovascular disease, nonfatal systemic embolism, stent thrombosis, and cardiovascular mortality.Results 32 (24.8%) patients early terminated the antiplatelet treatment and 22 (17.1%) patients terminated the rivaroxaban treatment. 26 (20.2 %) patients had hemorrhagic complications. The highest incidence of hemorrhage was observed within the first 2 months after the discharge. None of the bleedings was fatal. Composite endpoint events were observed in 24 (18.6 %) patients, including 14 (10.9 %) who died from cardiovascular causes.Conclusion      The compliance with the antiplatelet therapy was insufficient. The incidence of hemorrhagic complications was relatively high; minor and requiring medical attention hemorrhages mostly contributed to the structure of these complications. The observed incidence of recurrent ischemic events associated with a high mortality presents a more serious problem compared to hemorrhagic complications of the combination antiplatelet therapy and warrants a more aggressive tactics of the antiplatelet treatment in high-risk patients.

SummaryAcute coronary syndrome (ACS) is a medical emergency. Patients who survive the initial event remain at risk of recurrent cardiovascular events. In most cases, ACS is triggered by thrombosis after rupture of an atherosclerotic plaque. Key to thrombus formation at this site is the generation of thrombin, which not only converts fibrinogen to fibrin but also serves as a potent platelet agonist and induces platelet aggregation at the site of vascular injury. Although dual antiplatelet therapy is more effective for the prevention of recurrent events than aspirin alone after ACS, there remains an approximately 10 % risk of recurrent ischaemic events at one year. Recent studies have evaluated whether the addition of an anticoagulant to antiplatelet therapy reduces the risk of recurrent ischaemia after an ACS event. Rivaroxaban, an oral factor Xa inhibitor, attenuates thrombin generation. When used in conjunction with dual antiplatelet therapy in patients with stabilised ACS, rivaroxaban 2.5 mg twice daily significantly reduced the risk of the composite endpoint of cardiovascular death, myocardial infarction and stroke compared with placebo. Although it increased the risk of bleeding, rivaroxaban was associated with a reduction in mortality; a finding that supports the use of a dual-pathway approach that combines anticoagulant and antiplatelet therapy. This review explores the pathophysiology of ACS to provide perspective on the results of recent clinical trials with novel oral anticoagulants for ACS and to identify their potential role in this setting.

Abstract Antithrombotic therapy plays an essential role in the management of some of the most common and morbid medical conditions. Triple oral antithrombotic therapy (TOAT) is defined as the administration of both therapeutic oral anticoagulation (OAC) and dual antiplatelet therapy (DAPT) to patients with indications for both treatments. The current societal guidelines regarding TOAT are derived from observational studies and some trials of the use of warfarin in addition to antiplatelet therapy in patients with atrial fibrillation and a recent acute coronary syndrome or percutaneous coronary intervention. The general apprehension to administer TOAT is due to the heightened concern for bleeding, rendering warfarin's pharmacokinetic properties concerning. Newer anticoagulant agents may serve as appealing alternatives, and further investigations are warranted. The results of the recent trials that have studied the use of these agents in atrial fibrillation and acute coronary syndrome offer some useful applications to TOAT. Ultimately, selecting the most favorable antithrombotic strategy is going to involve weighing the risks and benefits for each patient.

Conflicting results have been reported so far in pooled analyses and studies evaluating the optimum duration of dual antiplatelet therapy (DAPT) in acute coronary syndrome (ACS) patients. However, randomized clinical trials dedicated to this specific setting of higher thrombotic risk patients have only recently been completed, pointing at the noninferiority of a shorter strategy as compared to the traditional 12-month DAPT, furthermore allowing to reduce the risk of major bleeding complications. Therefore, a reconsideration of current clinical practice and guidelines should be certainly be advocated in light of the most recent updates, especially among ACS patients treated with percutaneous coronary intervention (PCI) and modern drug-eluting stents (DES). Our aim was to provide a comprehensive review of the available evidence on the optimal DAPT duration in ACS patients.

Background: Atrial fibrillation (AF) is associated with increased morbidity in acute coronary syndrome patients, but impact on outcomes beyond 1 year is unclear. Methods: This was a post-hoc analysis from the long-tErm follow-uP of antithrombotic management patterns In acute CORonary syndrome patients (EPICOR) registry (NCT01171404), a prospective, observational study conducted in Europe and Latin America, which enrolled acute coronary syndrome survivors at discharge. Antithrombotic management patterns, mortality, a composite endpoint of death/new non-fatal myocardial infarction/stroke and bleeding events were assessed after 2 years of follow-up in patients with or without AF. Results: Of 10,568 patients enrolled, 397 (4.7%) had prior AF and 382 (3.6%) new-onset AF during index hospitalisation. Fewer patients with AF underwent percutaneous coronary intervention (52.1% vs. 66.6%; P<0.0001). At discharge, fewer AF patients received dual antiplatelet therapy (71.6% vs. 89.5%; P<0.0001); oral anticoagulant use was higher in AF patients but was still infrequent (35.0% vs. 2.5%; P<0.0001). Use of dual antiplatelet therapy and oral anticoagulants declined over follow-up with over 50% of all AF/no AF patients remaining on dual antiplatelet therapy (55.6% vs. 60.6%), and 23.3% (new-onset AF) to 42.1% (prior AF) on oral anticoagulants at 2 years. At 2 years, mortality, composite endpoint and bleeding rates were higher in AF patients (all P<0.0001) compared to patients without AF. On multivariable analysis, the risk of mortality or the composite endpoint was significant for prior AF ( P=0.003, P=0.001) but not new-onset AF ( P=0.88, P=0.92). Conclusions: Acute coronary syndrome patients with AF represent a high-risk group with increased event rates during long-term follow-up. Prior AF is an independent predictor of mortality and/or ischaemic events at 2 years. Use of anticoagulants in AF after acute coronary syndrome is still suboptimal.

Based on the recommendations of the European Heart Society and the results of clinical and register studies, the article highlights the complex issues that arise when prescribing antiplatelet therapy in patients with acute coronary syndrome, including with concomitant atrial fibrillation (AF); the promising strategies for managing the risk of ischemic and hemorrhagic events are described. Also a clinical case of a patient with acute coronary syndrome and AF is presented, illustrating the objective complexity of correct selection of antiplatelet therapy in such patients.

Aims Current guidelines strongly recommend antiplatelet therapy with aspirin plus a P2Y12 receptor inhibitor (dual therapy) for patients with acute coronary syndrome (ACS). To better understand how antiplatelet treatment is prescribed in clinical practice, the aim of this study was to provide a more detailed description of real-world patients with and without antiplatelet treatment after an ACS, their outcomes at one-year follow-up and the related integrated cost. Methods The ReS database, including more than 12 million inhabitants, was evaluated. During the accrual period ACS patients discharged alive were identified on the basis of ICD-IX-CM code. Antiplatelet drug prescriptions and healthcare costs were analysed over one-year follow-up. Results In 2014, of the 25,129 patients discharged alive after an ACS, 5796 (23%) did not receive any antiplatelet therapy during the first month after hospital discharge. Among them, 3846 (66%) subjects were prescribed an antiplatelet drug subsequently, while 7.7% did not receive any antiplatelet treatment during the whole following year. Dual therapy in the subgroup of patients undergoing a revascularization procedure ( n = 8436) was prescribed to 79.2% of cases and to 46.1% ( n = 4009) of medically managed patients. The patients not treated with an antiplatelet treatment in the first month showed the highest one-year healthcare costs, mostly due to hospital re-admissions. Conclusions This analysis of a large patient community shows that a considerable proportion of patients remained untreated with antiplatelet treatment after an ACS event. A clearer characterization of these subjects can help to improve the adherence to the current guidelines and recommendations.

The combination of atrial fibrillation (AF) and acute coronary syndrome (ACS) is a complex situation in which a three-dimensional risk—cardioembolic, coronary, and hemorrhagic—has to be carefully managed. Triple antithrombotic therapy (TAT) is burdened with a high risk of serious bleeding, while dual antithrombotic therapy with an anticoagulant (DAT) likely provides only suboptimal coronary protection early after stent implantation. Moreover, TAT precludes the advantages provided by the use of the latest and more potent P2Y12 inhibitors in ACS patients. Here, we aimed to simulate and compare the expected coronary, cardioembolic, and hemorrhagic outcomes offered by DAT, TAT, or modern dual antiplatelet therapy (DAPT) with aspirin plus one of the latest P2Y12 inhibitors in AF patients early after an ACS. The comparison of numbers needed to treat to prevent major adverse events with the various antithrombotic regimens suggests that AF–ACS patients at high ischemic and hemorrhagic risk and at moderately low embolic risk (CHA2DS2VASc score 2–4) might safely withhold anticoagulation after revascularization for one month taking advantage of a modern DAPT, with a favorable risk-to-benefit ratio. In conclusion, this strategy, not sufficiently addressed in recent European and North American guidelines or consensus documents, adds to the spectrum of treatment options in these difficult patients; it might be the best choice in a substantial number of patients; and should be prospectively tested in a randomized controlled trial.
