RATIONALE: Lisinopril or Coreg CR®, may help reduce side effects caused by trastuzumab. It is not yet known whether lisinopril or Coreg CR® are more effective than a placebo in reducing side effects caused by trastuzumab. PURPOSE: This phase II trial is studying lisinopril and Coreg CR® to see how well they work compared with a placebo in reducing side effects in patients with HER2-positive breast cancer receiving trastuzumab.
OBJECTIVES: Primary * The primary objective of this study is to determine if administration of lisinopril or Coreg CR®, compared to placebo, will reduce the incidence of trastuzumab-induced cardiotoxicity, as measured by LVEF, in patients receiving adjuvant, or neoadjuvant,therapy for HER2 positive breast cancer. Secondary * To determine whether subjects randomized to active agent have fewer interruptions in trastuzumab therapy due to cardiomyopathy. * To determine whether the treatment effect is consistent in anthracycline and nonanthracycline patient cohorts * To compare changes in HRQL among the treatment groups during the study intervention * To evaluate the long term effects on the prevention of cardiomyopathy and impact on HRQL for either or both study agents * To compare the predictive value of troponin I and BNP in the identification of trastuzumab-induced cardiotoxicity OUTLINE: This is a multicenter study. Patients are stratified according to chemotherapy comprising an anthracycline (yes vs no). Patients are randomized to 1 of 3 treatment arms. * Arm I: Patients receive oral lisinopril once daily. * Arm II: Patients receive oral Coreg CR® once daily. * Arm III: Patients receive oral placebo once daily. In all arms, study treatment begins with the first dose of trastuzumab and continues for up to 52 weeks or until the end of trastuzumab therapy. Quality of life is assessed using the EORTC QLQ-C30 questionnaire at baseline, at 52 weeks (or at the end of trastuzumab therapy), and at 18 and 24 months (or 6 and 12 months after the completion of trastuzumab). After completion of study treatment, patients are followed up at 3, 6, 9, and 12 months.

Number of Participants With Trastuzumab-Induced Cardiotoxicity After 52 Weeks of Treatment
Reduction in incidence of trastuzumab-induced cardiotoxicity after 52 weeks of treatment as measured by preservation of Left Ventricular Ejection Fraction (LVEF). Number of Patients who experienced a cardiotoxicity.
Time frame: 2 years
Number of Participants With LVEF Decrease to <50%
Number of Participants with Left Ventricular Ejection Fraction (LVEF) drop to \<50%
Time frame: 2 years
Number of Patients With Trastuzumab Course Interruption
Measure indicates the number of patients who had an interruption of trastuzumab for any reason
Time frame: 2 years
Quality-of-life Changes Between Baseline and 52-weeks
Quality-of-life changes as assessed by North European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ-C30), which measures the quality of life of cancer patients. Higher score indicates higher quality of life. Score range is 0-100. The questionnaire was administered at baseline and at 52 weeks.
Time frame: 52 weeks
Number of Participants With Cardiotoxicity-free Survival at 750 Days From Baseline
Number of Participants with cardiotoxicity-free survival at 750 days from baseline
Time frame: 2 years
