Primary Outcome Measures

Name	Time	Method
Change From Baseline in Resting Heart Rate at Week 14	Baseline, Week 14	Heartbeats in each minute were calculated and averaged to obtain the resting heart rate.
Change From Baseline in Resting Heart Rate at Week 6	Baseline, Week 6	Heartbeats in each minute were calculated and averaged to obtain the resting heart rate.
Change From Baseline in Resting Heart Rate at Week 26	Baseline, Week 26	Heartbeats in each minute were calculated and averaged to obtain the resting heart rate.

Secondary Outcome Measures

Name	Time	Method
Left Ventricular End-Systolic Dimension (LVESD) at Baseline, Week 14 and 26	Baseline, Week 14 and 26	Left Ventricular End-Systolic Dimension was measured by Ultrasound cardiogram.
Left Ventricular End-diastolic Dimension (LVEDD) at Baseline, Week 14 and 26	Baseline, Week 14 and 26	Left Ventricular End-diastolic Dimension was measured by Ultrasound cardiogram.
Change From Baseline in Resting Heart Rate at Week 3, 10 and 18	Baseline, Week 3, 10 and 18	Heartbeats in each minute were calculated and averaged to obtain the resting heart rate.
Left Ventricular Ejection Fraction (LVEF) at Baseline, Week 14 and 26	Baseline, Week 14 and 26	LVEF was defined as the fraction of blood (in percent) pumped out of the heart's left ventricular chamber with each heart beat and it is used to measure the cardiac output for the heart. Ultrasound cardiogram performed to measure LVEF.
Interventricular Septal Thickness (IVST) at Baseline, Week 14 and 26	Baseline, Week 14 and 26	Interventricular septal thickness was measured by Ultrasound cardiogram.
Mean 24 Hour, Day Time and Night Time Heart Rate	Baseline, week 6, 14 and end of treatment (Week 26)	Holter monitor was used to measure heart rate (24 hour, day time, night time).
Number of Participants With Arrhythmia	Baseline up to end of treatment (Week 26)	Holter monitor was used to diagnose arrhythmia.
Number of Participants With 24 Hour Heart Rate With More Than 70 Beats Per Minute (Bpm) and Less Than 55 Bpm	Baseline, week 6, 14 and end of treatment (Week 26)	Holter monitor was used to measure heart rate.
Ratio of Early (E) to Late (A) Ventricular Filling Velocities (E/A Ratio) at Baseline, Week 14 and Week 26	Baseline, Week 14 and Week 26	Early to late ratio was measured by ultrasound cardiogram.
6-Minute Walk Test	Baseline and End of treatment (Week 26)	6-min walk test was a practical simple test that requires a 100-feet hallway but no exercise equipment or advanced training for technicians. Walking is an activity performed daily by all but the most severely impaired participants. This test measures the distance that a participant can quickly walk on a flat, hard surface in a period of 6 minutes.
Quality of Life Based on the Medical Outcomes Study Item Short From Health Survey (SF-36) at Baseline and End of Treatment	Baseline, end of treatment (Week 26)	Short Form Health Survey (SF-36), an instrument composed by 8 subscales: Physical Functioning, Physical Role Function, Bodily Pain, General Health, Vitality, Social Functioning, Emotional Role Function and Mental Health. The individual question items (Likert scale 0-4) are first summed for each item under the various sections. Then, those summary scores are then standardized on a scale between 0 and 1 using the mean and standard deviation of the actual scores and finally, weighted to a scale between 0 and 100. The items contributing to a scale are scored so that a higher score represents better health, and they are averaged together to create the scale score. Each item is scored on a 0 to 100 range so that the lowest and highest possible scores are 0 and 100, respectively.
Number of Participants With Medicine Compliance Assessed by Medication Procession Ratio (MPR)	Up to Week 26	MPR is used to assess the medicine compliance. MPR is defined as the actual drug number taken by the participants divided by the drug number should be taken by the participants according to the protocol. MPR between 80%-100% is defined as good compliance. Medication rate of less than (\<) 80% or greater than (\>)100% is defined as insufficient compliance.
Number of Participants With All Cause Mortality, Cardiac Death, or Re-admission Due to Heart Failure	Up to Week 26	Number of participants with all-cause mortality, cardiac death, or re-admission due to heart failure was reported.
Quality of Life Based on Minnesota Living With Heart Failure (MLHF) at Baseline and End of Treatment	Baseline, end of treatment (Week 26)	MLHF questionnaire has 21 items. Questions assess the impact of frequent physical symptoms of heart failure and the effects of heart failure on physical and social functions. Each question had a possible score of 0 (best) to 5 (worst), for a total of 0 to 105. The higher the summed score, the worse is the impact of heart failure on a participant's quality of life.
Number of Participants With Abnormal Value of N-terminal Pro-B-type Natriuretic Peptide (NT Pro-BNP)	Baseline up to End of treatment (Week 26)	Routine blood tests was performed to measure NT Pro-BNP. The normal range for NT Pro-BNP varies from 0 picograms/milliliter (pg/mL) (lower limit of normal value) -125 pg/mL (upper limit of normal value).
Number of Participants With Clinically Relevant Systolic and Diastolic Blood Pressure	Screening (Week -2) up to Week 26	Blood pressure (systolic and diastolic) measurement was taken at sitting position, with the elbow at the same level with the heart. Number of participants with clinically relevant systolic and diastolic blood pressure reported based on the assessment of the investigator.
Number of Participants With New York Heart Association (NYHA) Class	Baseline, Week 26	The NYHA classification assesses the severity of symptoms of heart failure. Here NYHA class of II - IV was assessed. NYHA II: Slight limitation of physical activity, comfortable at rest, but ordinary physical activity results in undue breathlessness, fatigue or palpitation. NYHA III: Marked limitation of physical activity, comfortable at rest, but less than ordinary activity causes undue breathlessness, fatigue or palpitation. NYHA IV: Unable to carry on any physical activity without discomfort, symptoms at rest can be present. If any physical activity is undertaken, discomfort increased.
Percentage of Participants With Resting Heart Rate Less Than 70 Beats Per Minute (Bpm) and More Than 55 Bpm	Baseline up to Week 26	Resting heart rate measurement was taken at sitting position for a continuous record of 3 minutes. Heartbeats in each minute was calculated and averaged to obtain the resting heart rate.
