Primary Outcome Measures :
- Change from Baseline at Month 12 in Six-Minute Walk Test (6-MWT) [ Time Frame: Baseline, Month 12 ]
Secondary Outcome Measures :
- Change from Baseline at Month 12 in Kansas City Cardiomyopathy Questionnaire Overall Summary (KCCQ-OS) Score [ Time Frame: Baseline, Month 12 ]The KCCQ is a 23-item self-administered questionnaire quantifying 6 domains (symptoms, physical function, quality of life, social limitation, self-efficacy, and symptom stability) and 2 summary scores (clinical and overall summary [OS]). Scores are transformed to a range of 0-100, in which higher scores reflect better health status.
- Composite Endpoint of All-Cause Mortality, Frequency of Cardiovascular (CV) Events (CV Hospitalizations and Urgent Heart Failure [HF] Visits) and Change from Baseline in 6-MWT [ Time Frame: Up to Month 12 ]This composite endpoint will be analyzed using the win ratio method. This method combines all-cause mortality, frequency of CV events (CV hospitalizations and HF visits) and change from baseline in 6-MWT in a hierarchical fashion. The method uses pairwise comparisons for all possible active/placebo patient pairs. A 'win' represents a patient doing better based on the hierarchical comparison. The win ratio is the total number of 'winners' divided by the total number of 'losers' in the active group.
- Composite Endpoint of All-Cause Mortality and Frequency of All-Cause Hospitalizations and Urgent HF Visits [ Time Frame: Up to Month 12 ]The hazard rate of all-cause mortality and all-cause hospitalizations and urgent HF visits will be compared between treatment groups using an Andersen-Gill model.
