Abstract

This review aims to provide insights into contemporary therapeutic options for the treatment of patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) and compares current international guidelines. AF is a common cardiac arrhythmia and a major risk factor for stroke. The risk of stroke can be reduced with the use of oral anticoagulant (OAC) therapy. However, for patients with AF, PCI necessitates the use of combined antithrombotic therapies (OAC and antiplatelet therapies) to reduce thrombotic coronary complications. Optimal combinations and durations of OAC and/or antiplatelet therapy remains an area of clinical debate. Nuances exist within the current guidelines regarding duration and combination of antithrombotic therapy for AF patients requiring PCI. However, consensus was found across the following key points: (i) recent evidence supports a preferred role for a dual antithrombotic approach (OAC plus 1 antiplatelet); (ii) limited use of triple antithrombotic therapy is recommended across all guidelines for patients where the ischemic risk outweighs the risk of bleeding, with the duration to be kept as short as possible; and (iii) lifelong management using monotherapy with an OAC from 12 months post PCI is recommended for stable patients across all guidelines.
