Atrial fibrillation and coronary artery disease: a review on the optimal use of oral anticoagulants

Rev Cardiovasc Med. 2021 Sep 24;22(3):635-648. doi: 10.31083/j.rcm2203074.ABSTRACTAtrial fibrillation (AF) represents the most prevalent supraventricular arrhythmia in adults population and up to 15% of AF patients undergo percutaneous coronary intervention (PCI) for coronary artery disease (CAD) during their life. While oral anticoagulants (OACs) exert a protective effect in the setting of stroke prevention and systemic embolization in AF patients, patients undergoing PCI are recommended to receive dual antiplatelet therapy (DAPT) to reduce the risk of cardiovascular death, recurrent myocardial infarction and stent thrombosis. When these two scenarios coexist, as all antithrombotic regimens are burdened by an increase in bleeding risk, antithrombotic regimen and therapy duration must be cautiously tailored on individual patients' characteristics after attentive assessment of ischemic and bleeding risks. Non-vitamin K oral anticoagulants (NOACs), directly inhibiting either thrombin or factor Xa of the coagulation cascade, have progressively replaced warfarin as first choice OACs in several scenarios; recently, randomized controlled trials have compared antithrombotic regimens including NOAC molecules vs vitamin K antagonists in AF patients undergoing PCI to explore the efficacy and safety of NOACs in this setting. These studies have provided a deeper understanding of antithrombotic therapy after PCI in AF patients and have been promptly implemented by the most recent guidelin...
