Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Number of Participants That Experienced One Component of the Composite Clinical Endpoint of All Cause Death or Hospitalization for Heart Failure [ Time Frame: Entire follow-up (median = 4.7 years) ]

Secondary Outcome Measures :
  1. Number of Participants That Experienced One Components of the Composite Clinical Endpoint of All Cause Death or Cardiovascular Hospitalization [ Time Frame: Entire follow-up (median = 4.7 years) ]
    Cardiovascular hospitalization is defined as any hospitalization that may be attributed to a cardiovascular cause, including heart failure.

  2. Number of Participants That Died (Any Cause) [ Time Frame: Entire follow-up (median = 4.7 years) ]
  3. Number of Participants That Were Hospitalized for Heart Failure [ Time Frame: Entire follow-up (median = 4.7 years) ]
  4. Number of Participants That Experienced Cardiovascular Hospitalization [ Time Frame: Entire follow-up (median = 4.7 years) ]
