Group Intervention Description Early Epoetin Beta Therapy epoetin beta [NeoRecormon] Participants received immediate epoetin beta therapy starting at 2000 IU, subcutaneously once weekly up to four years to reach a target Hb level of 13-15 g/dL; with an individual Hb increase of at least 2 g/dL within approximately 3 months. Late Epoetin Beta Therapy epoetin beta [NeoRecormon] Participants received epoetin beta treatment starting at 2000 IU, subcutaneously once weekly up to four years only when a decline in Hb levels to \<10.5 g/dL had occurred in order to reach a target Hb of 10.5-11.5 g/dL.
- Primary Outcome Measures
Name Time Method Median Time to First Cardiovascular Event Up to 4 years The cardiovascular event was defined as any of the following: angina pectoris leading to hospitalization for at least 24 hours or prolongation of hospitalization, acute heart failure, fatal or non-fatal myocardial infarction, fatal or non-fatal stroke, sudden death, transient cerebral ischemic attack (TIA), peripheral vascular disease (amputation, necrosis), cardiac arrhythmias leading to hospitalization for at least 24 hours or prolongation of hospitalization. The time to occurrence of a cardiovascular event was determined as the time from randomization until any of the above listed events whichever occurred first. The first event per participant was used for the analysis. Only events confirmed by the Endpoint Committee were considered for analysis.
- Secondary Outcome Measures
Name Time Method Median Time to First Hospitalization Due to Cardiovascular Events Up to 4 years Time to first hospitalization due to cardiovascular events is defined as the time determined between randomization and first hospitalization due to cardiovascular events.
Duration of Hospitalization for Cardiovascular Events Up to 4 years The duration of hospitalization was the total number of days that a participant was hospitalized due to cardiovascular events. Participants with no hospitalization were excluded from analysis.
Median Time to Death Due to All Causes Up to 4 years Time to death due to all causes is the time determined between randomization and death due to all causes.
Number of Participants Who Died Due to All Causes Up to 4 years Number of participants who died due to all causes are presented in table below.
Median Time to First Cardiovascular Intervention Up to 4 years Time to first cardiovascular intervention is the time between randomization and first intervention determined for all cardiovascular interventions after randomization. Cardiovascular interventions considered were: angioplasty with or without stents/atherectomy, coronary artery bypass surgery, cardioverter defibrillator (CD) cardioversion/defibrillation, temporary pacemaker, permanent pacemaker and implantable cardioverter defibrillator (ICD) implantation.
Mean Change From Baseline in Left Ventricular Volume (LV Volume ) Baseline, Week 12, Week 24, Week 36, and Week 48 Left Ventricular Volume is the estimated of left ventricular end-diastolic volume (LVEDv) and left ventricular end-systolic volume (LVESV) determined by Echocardiogram. The change was calculated as week value minus baseline value.
Median Time to Death Due to Cardiovascular Events Up to 4 years Time to death due to cardiovascular events is the time determined between randomization and death due to cardiovascular events.
Number of Participants Who Died Due to Cardiovascular Events Up to 4 years The cardiovascular event was defined as any of the following: angina pectoris leading to hospitalization for at least 24 hours or prolongation of hospitalization, acute heart failure, fatal or non-fatal myocardial infarction, fatal or non-fatal stroke, sudden death, transient cerebral ischemic attack (TIA), peripheral vascular disease (amputation, necrosis), cardiac arrhythmias leading to hospitalization for at least 24 hours or prolongation of hospitalization.
Mean Change From Baseline in the Scores of Each of The Eight Health Scales of Quality of Life Based on Short Form-36 (SF-36) Questionnaire Baseline, Year 1, and Year 2 The Quality of life was assessed on the basis of a change from baseline in the scores of each of the eight health scales in the SF-36 questionnaire. The SF-36 is a standardized survey evaluating 8 domains (consisting of 2 components; physical and mental) of functional health and well-being: physical and social functioning, physical and emotional role (role-physical, role-emotional) limitations, bodily pain, general health (GH), vitality, mental health. The score for a section is an average of the individual question scores, which are scaled from 0 (worst level of functioning) to 100 (100=best level of functioning). The least squares mean (LSM) change from baseline was determined by Analysis of covariance (ANCOVA) model and presented for each of the eight health scale.
Number of Participants on Blood Pressure/Anti-Hypertensive Treatment According to Class Of Drugs Up to 4 years Anti-hypertensive is defined as class of drugs that are used to treat hypertension. Numbers (No.) of participants treated with at least one hypertensive medication/Treatment (Tt) according to class of drugs were reported.
Number of Participants With Marked Laboratory Abnormalities Baseline, every 3 months up to 4 years Marked abnormality of laboratory parameters is defined as the value which is outside the defined reference range of that respective parameter. Values above and below the given reference range were determined as High or Low range values of the laboratory parameter. Roche's standard reference ranges for laboratory test parameters were used for the analysis. The laboratory parameters with marked abnormality are platelets (reference range is 150-350 10\^9 cells/liter \[L\]), creatinine (reference range is 0-133 micromole per liter), albumin (reference range is 35.0-55 g/L), phosphate (reference range is 0.84-1.45 millimole per liter \[mmol /L\]) and potassium (reference range is 3.4-4.8 mmol /L).
Number of Participants Experiencing Worsening of New York Heart Association (NYHA) Class (CL) of Chronic Heart Failure From Baseline (BL) Up to 4 years The NYHA functional classification assesses the severity of symptoms of chronic heart failure and is comprised of four classes. Class I is defined as no limitation of physical activity, Class II is defined as slight limitation of physical activity, Class III is defined as marked limitation of physical activity, and Class IV is defined as unable to carry on any physical activity without discomfort. Shifts of participants from CL 0, CL I, CL II, CL III, CL IV at Baseline (Day 1) to CL 0, CL I, CL II, CL III, CL IV during the study period was determined and presented.
Mean Change From Baseline in Left Ventricular Ejection Fraction (LVEF) and Fractional Myocardial Shortening (FS) Baseline, Week 12, Week 24, Week 36, and Week 48 LVEF is a marker of left ventricular systolic function and determined by echocardiogram. It is expressed as the ratio of left ventricular stroke volume (LVSV) to left ventricular end-diastolic volume (LVEDV), and is measured as a percentage. FS is used as an estimate of myocardial contractility and determined by echocardiogram and measures as a percentage. The change for LVEF and FS was calculated as Week value minus baseline value.
Mean Values of Body Surface Area Baseline, Year 1, Year 2, Year 3, and Year 4. The body surface area (BSA) was determined by Echocardiogram. Absolute mean values of Echocardiography (ECHO) Parameter: Body surface area (BSA) at Baseline, Year 1, Year 2, Year 3 and Year 4 were calculated and presented.
Mean Values of Echocardiography Parameters Baseline, Year 1, Year 2, Year 3, and Year 4 Mean values of Echocardiography (ECHO) Parameters: Left Ventricular End Diastolic Diameter (LVEDD), Left Ventricular Posterior Wall Thickness (LVPWT), IV Septal Wall Thickness (IVSWT), LV End Systolic Diameter (LVESD), LV Relative wall thickness (LVRWT) at Baseline, Year 1, Year 2, Year 3 and Year 4 were presented.
Total Number of Cardiovascular Intervention Up to 4 years Cardiovascular intervention was defined by a clinical review of all concomitant treatments. The cardiovascular interventions considered were: angioplasty with or without stents/atherectomy, coronary artery bypass surgery, cardioverter defibrillator (CD) cardioversion/defibrillation, temporary pacemaker, permanent pacemaker and implantable cardioverter defibrillator (ICD) implantation. The total number of cardiovascular intervention was determined and presented by each cohort.
Mean Change From Baseline in Left Ventricular Mass Index (LVMI) Baseline, Week 12, Week 24, Week 36, and Week 48 LVMI is determined by echocardiogram. LVMI indexed to body surface area (gram/square meter) estimated by LV cavity dimension and wall thickness at end-diastole. The change was calculated as week value minus baseline value.
