Outcome Measures
Primary Outcome Measures
- To measure the composite endpoint of all-cause mortality or the first clinical events committee (CEC)-adjudicated nonfatal myocardial infarction [within 30 days after randomization]
- To measure the incidence of major bleeding. [during the index hospitalization]
Secondary Outcome Measures
- Incidence of minor and all bleeding [during the index hospitalization]
- To evaluate the combined and individual incidence of all-cause mortality, clinical events committee (CEC)-adjudicated nonfatal MI, stroke, or recurrent ischemia that required revascularization [within 14 and 30 days after randomization]
- To evaluate the incidence of all-cause mortality [within 6 months and 1 year after randomization]
- To evaluate the combined incidence of all-cause mortality or CEC-adjudicated nonfatal MI [within 14 days and all-cause mortality or nonfatal MI within 6 months after randomization]
Eligibility Criteria
Criteria
