- Composite Outcome of Cardiovascular (CV) Mortality and recurrent CV clinical events at Week 120 [ Time Frame: Baseline to Week 120 ]
- Change From Baseline in the 6MWT Distance at Week 120 [ Time Frame: Baseline to Week 120 ]The 6MWT is a submaximal exercise test that entails measurement of distance walked over a span of 6 minutes. The 6MWT provides information regarding functional capacity, response to therapy and prognosis across a range of chronic cardiopulmonary conditions.
- Change From Baseline in the Kansas City Cardiomyopathy Questionnaire (KCCQ) Scores at Week 120 [ Time Frame: Baseline to Week 120 ]
The Kansas City Cardiomyopathy Questionnaire (KCCQ) is a 23-item self-administered questionnaire developed to independently measure the patient's perception of their health status, which includes heart failure symptoms, impact on physical and social function, and how their heart failure impacts their quality of life (QOL) within a 2-week recall period.
The KCCQ tool quantifies the following six (6) distinct domains and two (2) summary scores. KCCQ responses are provided along a rating scale continuum with equal spacing from worst to best, with a higher score equaling a better score.
- CV Clinical Events at Week 120 [ Time Frame: Baseline to Week 120 ]
- CV Mortality at Week 120 [ Time Frame: Baseline to Week 120 ]
- Rate of All-Cause Mortality at Week 120 [ Time Frame: Baseline to Week 120 ]
