[Oral anticoagulants combined with aspirin in the prolonged treatment after acute coronary syndrome].

The incidence of death or myocardial infarction after acute coronary syndrome (ACS) is still high despite the widespread use of aspirin. Oral anticoagulant therapy (OAT) reducing thrombin activity has the potential to be beneficial when administered alone or in combination with aspirin after ACS. Low-intensity OAT in combination with aspirin is not superior to aspirin alone.
