- Change From Baseline in Log-Transformed N-Terminal Pro-Brain Natriuretic Peptide (NTproBNP) to Week 12 [ Time Frame: Baseline, Week 12 ]Log-Transformed N-Terminal Pro-Brain Natriuretic Peptide (NTproBNP) is a circulating plasma biomarker of cardiovascular function and prognosis in heart failure.
- Changes in Heart Function as Measured by Echocardiography, Left Ventricular End-Diastolic Volume (LVEDV), and Left Ventricular End-Systolic Volume (LVESV) From Baseline to Week 12 [ Time Frame: Baseline, Week 12 ]Left Ventricular End-Diastolic Volume (LVEDV) and Left ventricular end-systolic volume (LVESV) are measured echocardiography parameter. These are acquired during a non-invasive echocardiography examination.
- Changes in Heart Function as Measured by Echocardiography, Left Ventricular Ejection Fraction (LVEF), From Baseline to Week 12 [ Time Frame: Baseline, Week 12 ]The left ventricular ejection fraction work index (LVEF) is a calculated echocardiography parameter. LVEF is derived from the directly measured parameters left ventricular end-diastolic volume (LVEDV) and left ventricular end-systolic volume (LVESV). These 2 parameters are acquired during a noninvasive echocardiography examination. Formula: LVEF = 100*(LVEDV - LVESV)/LVEDV.
- Change From Baseline in Systolic and Diastolic Blood Pressure to Week 12 [ Time Frame: Baseline, Week 12 ]Blood pressure was measured by monitor measurements after 10 minutes resting in a supine position (3 measurements taken approximately 2 minutes apart).The changes in blood pressure were recorded and the mean of the three measurements was analyzed.
- Change From Baseline in Heart Rate to Week 12 [ Time Frame: Baseline, Week 12 ]Heart rate was measured after 10 minutes resting in a supine position (3 measurements taken approximately 2 minutes apart). The changes in heart rate were recorded and the mean of the three measurements was analyzed.
- Number of Subjects With Clinical Events (Heart Failure [HF] Hospitalization and Cardio-Vascular [CV] Mortality) [ Time Frame: Baseline until 16 weeks ]Clinical events (heart failure and mortality) were analyzed as CV death, and HF hospitalization at specified time points.
- Number of Subjects With Implantable Cardioverter Defibrillators Cardiac Resynchronization Therapy With Defibrillation (ICD/CRT-D) Therapy [ Time Frame: Baseline upto 16 weeks ]ICD / CRT with defibrillation therapy (CRT-D) included previous appropriate interventions such as shocks or anti-tachycardic pacing (ATP) when diagnostic of sustained ventricular tachycardias in pre defined rapid zone.
- Number of Subjects With Treatment-Emergent Adverse Events [ Time Frame: From the start of study treatment upto 5 days after the last dose of study drug ]An adverse event (AE) was any untoward medical occurrence in a subject who received study drug without regard to possibility of causal relationship. A serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly; and another medically important serious event as judged by the investigator. AEs are considered to be treatment-emergent if they have started or worsened after first application of study drug up to 5 days after end of treatment with study drug.
- Change in Biomarkers From Baseline to Week 12: Osteopontin (ng/mL) [ Time Frame: Baseline, Week 12 ]
- Change in Biomarkers From Baseline to Week 12: TIMP-4 (pg/mL) [ Time Frame: Baseline, Week 12 ]TIMP-4: tissue inhibitor of matrix metalloproteinases 4
- Change in Biomarkers From Baseline to Week 12: cGMP (Pmol/mL) [ Time Frame: Baseline, Week 12 ]cGMP: cyclic guanosine monophosphate
- Change in Biomarkers From Baseline to Week 12: PIIINP (mcg/L) [ Time Frame: Baseline, Week 12 ]PIIINP: pro-collagen III N-terminal peptide
- Change in Biomarkers From Baseline to Week 12: GDF-15 (pg/mL) [ Time Frame: Baseline, Week 12 ]GDF-15: growth differentiation factor 15
- Change in Biomarkers From Baseline to Week 12: ST2 (pg/mL) [ Time Frame: Baseline, Week 12 ]ST2: suppression of tumorigenicity 2
- Change in Biomarkers From Baseline to Week 12: Gal-3 (μg/mL) [ Time Frame: Baseline, Week 12 ]Gal-3: Galectin-3
