Outcome Measures

Primary Outcome Measures :
  1. Composite incidence of all-cause mortality, clinical deterioration, bailout, and major bleeding [ Time Frame: From the time of primary treatment for high-risk pulmonary embolism through hospital discharge or 45 days, which ever comes first. ]
    Endpoint events will be assessed from the time of treatment of the high-risk pulmonary embolism through hospital discharge for the high-risk PE, or through 45 days post treatment for high-risk pulmonary embolism, whichever comes first..

Criteria

Inclusion Criteria:
