Dual antiplatelet therapy (DAPT) is required following percutaneous coronary intervention (PCI) to prevent stent thrombosis. The optimal antithrombotic therapy following PCI for patients with an indication for long-term oral anticoagulation (OAC) is uncertain. DAPT and OAC, a combination known as ‘triple therapy’, reduces cardiovascular event rates but is associated with a substantial risk of bleeding. Recent data suggest that the duration of DAPT (and thereby triple therapy in those who also require OAC) can be limited to 1–3 months following newgeneration drug-eluting stent deployment, and that aspirin may be omitted from triple therapy, without increasing the rate of ischaemic cardiovascular events. The increasing use of non-vitamin K antagonist oral anticoagulants and new antiplatelet agents (prasugrel and ticagrelor) has further complicated antithrombotic prescribing. This article aims to provide a summary of the evidence regarding antithrombotic therapy after PCI in patients who have an indication for OAC and to provide a framework to aid clinical decision-making in this area.

The Impact

Abstract About 20% of all atrial fibrillation (AF) patients develop coronary artery disease, which requires coronary stenting [percutaneous coronary intervention (PCI)]. Thus, this subcohort of AF patients may require aggressive antithrombotic therapy encompassing vitamin K antagonist (VKA) or non-vitamin K antagonist oral anticoagulants (NOAC) plus aspirin and a P2Y12 inhibitor. At present, four clinical Phase IIIb trials using dabigatran, rivaroxaban, apixaban, or edoxaban, were published. These studies assessed the impact of NOACs as a part of DAT therapy vs. triple therapy. Compared with triple therapy, NOAC-based DAT has been shown to be associated with reduced major bleeding as well as intracranial haemorrhages. The benefit, however, is somewhat counterbalanced by a higher risk of stent-related ischaemia during the early phase of dual therapy. Thus, triple therapy after stenting is appropriate for at least 14 days with a maximum of 30 days. Thereafter, DAT including a NOAC is the therapy of choice in AF PCI patients to reduce the risk of bleeding during a 1 year of follow-up compared to VKA-based regimes. The present review summarizes the published study results and demonstrates differences in trial design and reported outcomes.

AbstractPatients with atrial fibrillation (AF) on long-term oral anticoagulation (OAC) either have underlying coronary artery disease or suffer from acute coronary syndromes necessitating a percutaneous coronary intervention (PCI). In such a scenario, an amalgamation of antiplatelet and antithrombotic therapy (conventionally called as “triple therapy”) is obligatory for preventing coronary ischemia and stroke. But such ischemic benefits are accrued at the cost of increased bleeding. We also now know that bleeding events following PCI are related to increased mortality. Balancing the bleeding and ischemic risks is often a clinical dilemma. With the advent of novel oral anticoagulants (NOAC's) with preserved efficacy and attenuated bleeding rates, anticoagulation in AF is undergoing paradigm shift. The spotlight is now shifting from conventional triple therapy (vitamin-K antagonist + dual antiplatelet therapy [VKA + DAPT]) to novel dual therapy (NOAC + single antiplatelet therapy [SAPT]) in situation of anticoagulated AF patients undergoing PCI. Such a strategy aims to ameliorate the higher bleeding risk with conventional VKA's while retaining the ischemic benefits. In this review, we briefly discuss the need for combination therapy, trials of novel dual therapy, strategies for mitigating bleeding, the current guidelines, and the future perspectives in AF undergoing PCI with stent(s).

Antithrombotic Management

The optimal antithrombotic treatment regimen for patients with atrial fibrillation undergoing percutaneous coronary intervention with stent implantation represents a challenge in clinical practice. In 2016, an updated opinion of selected experts from the United States and Canada on the treatment of patients with atrial fibrillation undergoing percutaneous coronary intervention was reported. After the 2016 North American consensus statement on the management of antithrombotic therapy in patients with atrial fibrillation undergoing percutaneous coronary intervention, results of pivotal clinical trials assessing the type of oral anticoagulant agent and the duration of antiplatelet treatment have been published. On the basis of these results, this focused update on the antithrombotic management of patients with atrial fibrillation undergoing percutaneous coronary intervention recommends that a non–vitamin K antagonist oral anticoagulant be preferred over a vitamin K antagonist as the oral anticoagulant of choice. Moreover, a double-therapy regimen (oral anticoagulant plus single antiplatelet therapy with a P2Y 12 inhibitor) by the time of hospital discharge should be considered for most patients, whereas extending the use of aspirin beyond hospital discharge (ie, triple therapy) should be considered only for selected patients at high ischemic/thrombotic and low bleeding risks and for a limited period of time. The present document provides a focused updated on the rationale for the new expert consensus–derived recommendations on the antithrombotic management of patients with atrial fibrillation treated with oral anticoagulation undergoing percutaneous coronary intervention.

The article presents an analytical review of the studies aimed at determining the optimal antithrombotic therapy in patients with atrial fibrillation undergoing elective or emergency percutaneous coronary intervention (PCI) due to the development of acute coronary syndrome (ACS). The results of the WOEST study are analysed. This study was the first to demonstrate an opportunity to safely discontinue administration of aspirin as part of the multicomponent antithrombotic therapy that included warfarin as an anticoagulant. Three studies were analysed - PIONEER AF-PCI, RE-DUAL-PCI and AUGUSTUS, where direct oral anticoagulants (DOACs) - rivaroxaban, dabigatran and apixaban were used as anticoagulants as part of the multicomponent therapy. The results of these studies formed the backbone of the updated European guidelines for the diagnosis and treatment of atrial fibrillation, 2020. The guidelines offer to divide patients with AF and ACS, who require multicomponent antithrombotic therapy, into two categories. The first group includes AF patients with uncomplicated PCI without a high risk of stent thrombosis, as well as patients with a risk of bleeding that prevails over the risk of stent thrombosis. The second category of patients, in contrast, is characterized by a high risk of stent thrombosis, which prevails over the risk of bleeding. In the absence of contraindications, the patients of both categories should choose DOAC as an anticoagulant and be prescribed clopidogrel as a P2Y12 inhibitor for 12 months. In AF patients with uncomplicated PCI without a high risk of stent thrombosis, as well as in patients with a risk of bleeding, which prevails over the risk of stent thrombosis, the period of treatment with the second antiplatelet drug (aspirin) should belimited to the hospital stay. Patients at increased risk of stent thrombosis and reduced risk of bleeding can extend the aspirin therapy for 1 month. The approaches to the choice of the duration and composition of the multicomponent antithrombotic therapy in AF patients taking oral anticoagulants after elective PCI are similar to those in ACS patients, except for the duration of clopidogrel therapy, which is reduced to 6 months in all patients.

Background: Limited data are available regarding real-world prescribing in patients with an indication for oral anticoagulation (OAT) who undergo percutaneous coronary intervention (PCI). Most current guidelines recommend a period of triple therapy with OAT and dual antiplatelet (DAPT) agents over dual therapy with an OAT and DAPT but the clinical benefit is still unclear giving rise to limited evidence-based recommendations. Aim: To analyze the appropriateness of OAT and anti-platelet strategies post PCI in a real-world cohort of patients in 2 academic teaching hospitals. Methods and Results: In total, 103 patients were retrospectively analyzed. As the initial 3 month stragey, 97 patients (94.2%) received triple therapy, 4 received Dual Therapy (3.9%) and 2 received DAPT (1.9%). Patients with predominant bleeding risk were significantly less likely to receive triple therapy (75% vs. 95.7% vs. 95.8%, P < 0.05). Apixaban was the most common OAT (65.7%) which in most cases was prescribed at an inappropriately reduced dose of 2.5 mg BD (80.4%). The MACE, bleeding and all-cause mortality rates did not differ significantly between groups. Discussion: Our study demonstrates the widespread use of triple therapy for the first 3 months of treatment in 2 Irish academic hospitals. DOACs were prescribed in most cases at reduced doses not currently known to prevent stroke. This study highlights the need for more explicit management algorithms to improve evidence-based management in this area.
