Study Endpoints
Primary Endpoints
Number of Participants With First Occurrence of Cardiovascular (CV) Mortality or Hospitalization Due to Heart Failure (HF)
Randomization up to the date when the last enrolled participant had been followed up for 1 year (up to 1744 days)

CV mortality was defined as any death due to HF, myocardial infarction, cardiac arrhythmia, stroke or cerebral vascular accident, other CV cause (such as aneurysm or pulmonary embolism). Hospitalization due to HF was defined as an overnight stay, or longer, in a hospital environment (emergency room, observation unit or in-patient care, or similar facility including admission to a day care facility) due to HF. Hazard ratio of Eplerenone versus placebo for first occurrence of the event was obtained from a Cox proportional hazards model.

Number of Participants With First Occurrence of Cardiovascular (CV) Mortality or Hospitalization Due to Heart Failure (HF) (Adjudicated): Up to Cut-off Date
Baseline (30 March 2006) up to 50 months (cut-off date: 25 May 2010)

CV mortality is defined as death due to heart failure, myocardial infarction, cardiac arrhythmia, stroke or cerebral vascular accident (CVA), other CV cause (such as aneurysm or pulmonary embolism). Hospitalization due to HF is defined as an overnight stay, or longer, in a hospital environment (emergency room, observation unit or in-patient care, or similar facility including admission to a day care facility) due to HF as the primary reason for hospitalization as determined by the endpoint committee adjudicator.

Number of Participants With First Occurrence of Cardiovascular (CV) Mortality or Hospitalization Due to Heart Failure (HF) (Adjudicated)
Baseline (30 March 2006) up to 59.5 months (complete DB phase: 18 March 2011)

CV mortality is defined as death due to heart failure, myocardial infarction, cardiac arrhythmia, stroke or cerebral vascular accident (CVA), other CV cause (such as aneurysm or pulmonary embolism). Hospitalization due to HF is defined as an overnight stay, or longer, in a hospital environment (emergency room, observation unit or in-patient care, or similar facility including admission to a day care facility) due to HF as the primary reason for hospitalization as determined by the endpoint committee adjudicator.
