Outcomes

Primary Outcomes

Change From Baseline in N-terminal Pro-brain Natriuretic Peptide (NT-proBNP)

Evaluation of NT-proBNP was performed by a central laboratory. Change from baseline in NT-proBNP was presented as a ratio where the ratio was calculated as the NT-proBNP value at 12 weeks over the NT-proBNP value at baseline. A ratio \< 1 indicates improvement.

Time frame: Baseline, 12 weeks

Secondary Outcomes

Change From Baseline in NT-proBNP and Brain Natriuretic Peptide (BNP)

Evaluation of NT-proBNP and BNP was performed by a central laboratory. Change from baseline in NT-proBNP and in BNP was presented as a ratio where the ratio for NT-proBNP was calculated as the NT-proBNP value at 36 weeks over the NT-proBNP value at baseline, and the ratio for BNP was calculated as the BNP value at 36 weeks over the BNP value at baseline. A ratio \< 1 indicates improvement.

Time frame: baseline, 36 weeks

Change From Baseline in Plasma Cyclic Guanine Monophosphate (cGMP)

Evaluation of cGMP was performed by a central laboratory. Change from baseline in cGMP was presented as a ratio where the ratio was calculated as the cGMP value at 36 weeks over the cGMP value at baseline. A ratio \< 1 indicates improvement.

Time frame: baseline, 36 weeks

Change From Baseline in Echocardiography (ECHO) Parameters: Left Ventricular End (LVE) Diastolic Diameter, LVE Systolic Diameter, Septal End Diastolic Thickness, Posterior LV Wall End Diastolic Thickness, Relative Wall Thickness, Left Atrial Dimension

A limited two-dimensional and Doppler ECHO examination was done to assess ECHO parameters. A negative change from baseline indicates improvement.

Time frame: Baseline, 36 weeks

Change From Baseline in Echocardiography Parameters: LVE Diastolic Volume, LVE Systolic Volume, Left Ventricular Stroke Volume, Left Atrial Volume

Change From Baseline in Kansas City Cardiomyopathy Questionnaire (KCCQ) Overall Summary Score and Individual Domain Summary Scores

The KCCQ is a self-administered questionnaire. It contains 23 items, covering physical function, clinical symptoms, social function, self-efficacy and knowledge, and quality of life, each with different Likert scale wording, including limitations, frequency, bother, change in condition, understanding, levels of enjoyment and satisfaction. Scores are transformed to a range of 0-100, in which higher scores reflect better health status. A positive change from baseline indicates improvement.

Percentage of Participants With Clinical Composite Assessment of Improved, Unchanged or Worsened

The clinical composite assessment is defined as follows: Improved = a) participant improved (markedly or moderately) in the global assessment of disease activity with no worsening of NYHA functional class and no major adverse cardiovascular event or b) participant improved in NYHA functional class with no worsening (markedly or moderately) in the global assessment of disease activity and no major adverse cardiovascular event. Worsened = participant worsened (markedly or moderately) in the global assessment of disease activity or in NYHA functional class or experienced a major adverse cardiovascular event. Unchanged = participant does not meet the definition for improved or worsened.

Percentage of Participants With New York Heart Association (NYHA) Class I, II, II or IV

The NYHA Functional Classification classifies patients' heart failure according to the severity of their symptoms. The classification is as follows: Class I: no limitation of physical activity, ordinary physical activity does not cause undue fatigue, palpitation, or dyspnea (shortness of breath); Class II: slight limitation to physical activity, comfortable at rest, ordinary physical activity results in fatigue, palpitation or dyspnea; Class III: marked limitation of physical activity, comfortable at rest, less than ordinary activity causes fatigue, palpitation or dyspnea; Class IV: unable to carry on any physical activity without discomfort, symptoms of heart failure at rest, if any physical activity is undertaken, discomfort increases.
