Arms and Interventions

Arm Intervention/treatment
Experimental: Group 1 (Early Epoetin Beta)
Along with their standard treatment participants will receive epoetin beta at a starting dose of 2000 International Units (IU) subcutaneously (SC) once weekly to reach and maintain target hemoglobin (Hb) between 13 and 15 grams per deciliter (g/dL), for 15 months. Epoetin beta doses will be adjusted according to individual participant's Hb level. Standard treatment will be as per investigator discretion.
 Drug: Epoetin beta
Other Name: NeoRecormon
Active Comparator: Group 2 (No/Late Epoetin Beta)
Participants will receive their standard treatment for 15 months but no treatment for anemia correction unless Hb level will be less than (<) 10.5 g/dL on 2 consecutive visits of 2 weeks interval or the Hb level will be <10 g/dL on a single determination. In such cases participants could receive epoetin beta at a starting dose of 2000 IU SC once weekly to reach and maintain a target Hb level of 10.5 to 11.5 g/dL. Standard treatment will be as per investigator discretion.
 Drug: Epoetin beta
Other Name: NeoRecormon


Outcome Measures

Primary Outcome Measures :
  1. Change From Baseline in Left Ventricle Mass Index (LVMI) at Month 15 [ Time Frame: Baseline, Month 15 ]
    LVMI (in g/m^2) = (0.8 [1.04 {(LVEDD + IVS + PWT)^3 - (LVEDD)^3}] + 0.6) divided by BSA. Here, LVEDD = left ventricular end diastolic diameter (in centimeters [cm]); PWT = left ventricular posterior wall thickness in diastole (in cm); IVS = interventricular septal wall thickness in diastole (in cm). Echocardiogram was performed at baseline and Month 15 to interpret LVMI which was expressed in grams per meter square (g/m^2).


Secondary Outcome Measures :
  1. Left Ventricular End Systolic Volume Index (LVESVI) [ Time Frame: Baseline, Months 6 and 15 ]
    LVESVI was calculated by dividing left ventricular end systolic volume (LVESV) (in milliliters [mL]) with body surface area (BSA) (in meter square [m^2]). LVESVI is presented in milliliter per meter square (mL/m^2).

  2. Left Ventricular End Diastolic Volume Index (LVEDVI) [ Time Frame: Baseline, Months 6 and 15 ]
    LVEDVI was calculated by dividing left ventricular end diastolic volume (LVEDV) (in mL) BSA (in m^2). LVEDVI was presented in mL/m^2.

  3. Fractional Myocardial Shortening (FS) [ Time Frame: Baseline, Months 6 and 15 ]
    FS was calculated as: ([LVEDD - LVESD] divided by LVEDV) multiplied by 100; where LVEDD = left ventricular end diastolic diameter (in centimeters [cm]), LVESD = left ventricular end systolic diameter (in cm), LVEDV = left ventricular end diastolic volume (in mL). FS is expressed in percentage of LVEDV.

  4. Left Ventricular Ejection Fraction (LVEF) [ Time Frame: Baseline, Months 6 and 15 ]
    LVEF was calculated as ([LVEDV - LVESV], divided by LVEDV) multiplied by 100; where LVEDV = left ventricular end diastolic volume (in mL), LVESV = left ventricular end systolic volume (in mL). LVEF is expressed in percentage of LVEDV.

  5. Percentage of Participants With Stable Hb Levels Between 13 to 15 g/dL [ Time Frame: Week 26 up to Week 64 ]
