ABSTRACT
Patients with atrial fibrillation (AF) are at increased risk for coronary artery disease (CAD). After percutaneous coronary intervention (PCI), the antithrombotic therapy consists of a combination of anticoagulant and antiplatelet agents to reduce the ischemic and thromboembolic risk, at the cost of increased bleeding events. In the past few years, several randomized clinical trials involving over 12,000 patients have been conducted to compare the safety of vitamin K antagonist (VKA) and direct-acting oral anticoagulants (DOACs) in association with a single- or double-antiplatelet agent, in the so-called dual- (DAT) or triple-antithrombotic therapy (TAT). These studies and several meta-analyses showed a consistent benefit for reducing bleeding events of DAT over TAT and of DOAC over VKA, without concerns about ischemic endpoints, except for a trend for increased stent thrombosis risk. The present paper examines current international guidelines' recommendations and reviews clinical trials, meta-analyses, and observational studies conducted on AF patients treated with DAT or TAT after PCI for acute coronary syndromes.
