Antithrombotic Treatment in Acute Coronary Syndrome and Atrial Fibrillation

Víctor Mauro


The incidence of patients with chronic atrial fibrillation (AF) who also present with non-ST-segment elevation acute coronary syndrome varies between 10% and 30% according to registries (1, 2). The indication of anticoagulant drugs to reduce systemic embolism poses the need to use dual antiplatelet therapy to prevent recurrent ischemic complications in patients initially treated with a conservative or invasive strategy with percutaneous coronary intervention (PCI). The challenge of individualizing the patient with the most beneficial balance between ischemic and bleeding risk is usually very controversial in this population in daily clinical practice, since there is no evidence with adequate consistency that allows consensus on standardized behaviors. Below we will briefly review the studies performed, placing emphasis on their limitations.
