Summary:

      This phase IIb trial studies how well low-dose carvedilol works in preventing heart failure
      in cancer survivors exposed to high dose anthracyclines for management of childhood cancer.
      Patients who received high-dose anthracycline chemotherapy are at a much greater risk for
      developing heart failure compared to survivors who didn't get any anthracycline chemotherapy.
      Heart failure happens when the heart muscle has been weakened and can't pump blood as well as
      it should. Carvedilol may help lower the risk of cardiovascular complications.
    

Eligibility criteria:

        Inclusion Criteria:

          -  Males and females must weigh >= 40 Kg

          -  Patient must have had a cancer diagnosis < 22 years of age, irrespective of current
             age

          -  Patient must have a lifetime cumulative anthracycline dose of >= 250 mg/m^2
             DOXOrubicin equivalent without the protection of dexrazoxane (Zinecard) therapy; the
             anthracycline dose threshold must be met as part of the treatment of a cancer that was
             diagnosed at < 22 years of age

               -  Note: Institutional records (e.g., clinic note, treatment summary, chemotherapy
                  roadmap) can be used to document lifetime receipt of anthracycline dose

          -  Patient must have completed cancer treatment >= 2 years prior to study enrollment

          -  Receiving treatment for cardiomyopathy or heart failure

          -  Ejection fraction of < 50% (by radionuclide angiogram or echocardiogram) or shortening
             fraction of < 25% (by echocardiogram)

               -  Note: for instances where both are reported, and one is below the threshold, the
                  site will have the option to re-measure it centrally at the core lab

          -  Uncorrected primary obstructive or severe regurgitative valvular disease:

             sick sinus syndrome)

          -  Bradycardia: heart rate < 50 beats per minute (BPM)

          -  Use of an investigational drug or beta adrenergic blockers, including metoprolol,
             sotalol, within 30 days of enrollment

          -  Low resting systolic blood pressure: < 90 mmHg

          -  Use of any other blood pressure lowering medication for treatment of hypertension
             within 30 days of enrollment except calcium channel blockers and diuretics

          -  History or current clinical evidence of moderate-to-severe obstructive pulmonary
             disease or reactive airway diseases (i.e. asthma) requiring therapy
