The purpose of this study is to compare the use of ticagrelor alone versus ticagrelor and aspirin together. Both ticagrelor and aspirin stop platelets from sticking together and forming a blood clot that could block blood flow to the heart. This study will look to determine the effectiveness and safety of ticagrelor alone, compared to ticagrelor plus aspirin in reducing clinically relevant bleeding and in reducing ischemic adverse events among high-risk patients who have had a percutaneous intervention with at least one drug-eluting stent. A patient is considered high-risk if they meet certain clinical and/or anatomic criteria.
Up to 9000 subjects will be enrolled at the time of their index PCI. Subjects meeting randomization eligibility criteria at 3 months post enrollment will be randomized to either ticagrelor plus aspirin or ticagrelor plus placebo for an additional 12 months. Follow-up clinic visits will be performed at 3 months, 9 months and 15 months post enrollment.
