An update on antithrombotic therapy in atrial fibrillation patients in long-term ambulatory setting after percutaneous coronary intervention: where do we go from here?

INTRODUCTION: In the treatment of patients with atrial fibrillation (AF) who undergo percutaneous coronary intervention (PCI), it is unclear which combination of antithrombotic drugs is preferable and which is the optimal duration of treatment. AREAS COVERED: The authors review the available evidence in this area resulting from single studies and meta-analyses. In the absence of direct head-to-head comparisons between different non-vitamin K oral anticoagulants (NOAC), the authors review the available studies with NOACS in these patients and derived indirect comparisons. EXPERT OPINION: In patients with AF who undergo PCI, a dual antithrombotic strategy which includes a NOAC plus single antiplatelet therapy with a P2Y12 inhibitor (preferably clopidogrel) should be considered as the preferred treatment option in most cases. Oral anticoagulation associated with dual antiplatelet therapy (triple antithrombotic therapy) should be offered for no longer than 30 days to patients with very high thrombotic and low hemorrhagic risk. It is unclear whether the dual antithrombotic strategy should be continued beyond 12 months in patients at high risk of thrombotic events. Additional data from adequately powered controlled studies are needed to support the long-term efficacy of this strategy and to establish the best patient-tailored approach in this complex scenario.
