- Primary Outcome Measures
Name Time Method Time to Cardiovascular Death, Myocardial Infarction, Hospitalization for Unstable Angina, Stroke, or Coronary Revascularization Events that occurred from randomization to the last confirmed survival status date; the median duration of follow-up was 26 months. KM estimates at 6, 12, 18, 24, 30 and 36 months are reported. All deaths and potential endpoint events were adjudicated by an independent external Clinical Events Committee (CEC) led by the Thrombolysis in Myocardial Infarction (TIMI) Study Group, using standardized definitions based on the "Standardized Definitions for Cardiovascular and Stroke End Point Events in Clinical Trials and the Third Universal Definition of Myocardial Infarction".
Time to cardiovascular death, myocardial infarction, stroke, hospitalization for unstable angina, or coronary revascularization was defined as the time from randomization to the first occurrence of any component of the composite endpoint and was analyzed using Kaplan-Meier (KM) survival analysis. KM estimates of the percentage of participants with an event are reported. Participants with no event were censored based on last non-fatal potential endpoint collection date.

The diagnosis of myocardial infarction required the combination of:
* Evidence of myocardial necrosis (either changes in cardiac biomarkers or post-mortem pathological findings); and
* Supporting information derived from the clinical presentation, electrocardiographic changes, or the results of myocardial or coronary artery Imaging.

* Dyspnea
* Decreased exercise tolerance
* Fatigue
* Other symptoms of worsened end-organ perfusion or volume overload
4. Evidence of new or worsening HF consisting of at least 2 physical exam findings or 1 physical exam finding and at least 1 laboratory criterion
