The development of antiplatelet and antithrombotic therapies, in addition to interventionist strategy, has resulted in great improvements in the outcomes of patients with non-ST-segment elevation acute coronary syndrome. Parallel to therapeutic advances, bleeding, which can be induced during management, increases the risk of recurrent ischemia, myocardial infarction and death. The present literature review describes the benefits and bleeding risks of each medication or intervention strategy and suggests guidelines for managing these patients.
