Primary Outcome Measures:
  • Occurrence of Heart Failure (HF) Related Adverse Event (AE) [ Time Frame: From 6 month to the 12 month visit ] [ Designated as safety issue: No ]
    Number of participates with HF realted adverse event will be reported. Time to the first HF related Adverse event in the "Follow-up Period" from the 6-month visit to the 12-month visit is compared between two risk groups. The goal was to test if there is a significant difference in time to first HF-related adverse event between two groups. A heart failure related (HF-related) adverse event is defined as an adverse event that results in a subject's worsening HF or related to the heart's inability to meet the metabolic demands of the body.


Secondary Outcome Measures:
  • Occurrence of Heart Failure (HF) Related Healthcare Utilization (HU) [ Time Frame: 6 month to the 12 month visit ] [ Designated as safety issue: No ]
    Number of participates with HF realted healthcare utilization will be reported. Time to the first HF-related healthcare utilization in the "Follow-up Period" from the 6-month visit to the 12-month visit is compared between two risk groups. The goal was to test if there is a significant difference in time to first HF-related healthcare utilization between two groups. A heart failure related (HF-related) healthcare utilization is defined as unscheduled office visits, hospitalizations, urgent care visits, and emergency room visits which is resulted by heart failure related adverse event.

  • Occurrence of Heart Failure (HF) Related Pulmonary Congestion Event (PCE) [ Time Frame: 6 month to the 12 month visit ] [ Designated as safety issue: No ]
    Number of participates with HF related pulmonary congestion event will be reported. Time to the first HF related pulmonary cogestion event in the "Follow-up Period" from the 6-month visit to the 12-month visit is compared between two risk groups to see if there is significant difference. A HF related pulmonary congestion event is defined as hospitalization with signs and/or symptoms of pulmonary congestion, or outpatient treatment with IV diuretics due to exacerbation of HF with signs and/or symptoms of pulmonary congestion.
