Acute coronary syndrome (ACS) is a continuum of disease that includes non-ST-segment elevation ACS and ST-segment elevation myocardial infarction. The purpose of this article is to define the developing role of ticagrelor in ACS and compare it to currently available P2Y12 receptor inhibitors. While clopidogrel remains the "workhorse" P2Y12 receptor inhibitor for many patients with ACS and prasugrel has an established role in select situations, clinicians must now assimilate the evolving role of ticagrelor. Although ticagrelor offers important advances in the management of ACS (eg, reversibility), there are also notable clinical considerations (eg, unique adverse effects such as dyspnea). Based on the current evidence, we propose an algorithm to aid clinicians in the selection of a P2Y12 receptor inhibitor for patients with ACS in various clinical situations.
