Outcome Measures
Primary Outcomes (1)
Hierarchical composite of time to death, stroke, myocardial infarction, repeat revascularization and any graft failure.
This is a composite endpoint to be compared between groups in a hierarchical order using the win ratio method. The following hierarchy is pre-specified: 1. Time to all-cause mortality 2. Time to stroke 3. Time to myocardial infarction 4. Time to coronary revascularization 5. Presence of graft failure at 12-month imaging follow-up or on unscheduled imaging prior to 12 month
1 year
Secondary Outcomes (3)
Hierarchical composite of time to death, stroke, myocardial infarction, Bleeding Academic Research Consortium (BARC) type 3 bleeding, repeat revascularization and any graft failure.
1 year
Hierarchical composite of time to death, stroke, myocardial infarction, repeat revascularization and 5-year time-averaged disease-specific (Seattle Angina Questionnaire [SAQ]-7) quality of life (QoL) score
5 years
Hierarchical composite of time to death, stroke, myocardial infarction, BARC type 3 bleeding, repeat revascularization and 5-year time-averaged SAQ-7 QoL score.
5 years
Study Arms (2)
Ticagrelor 90 mg + Low-Dose Aspirin
EXPERIMENTALLow-Dose Aspirin Alone
ACTIVE COMPARATORInterventions
Ticagrelor 90 mg twice daily taken orally for one month
75-150 mg once daily taken orally
