2 Clinical Trials for Various Conditions
This is a pilot prospective cohort study, in adult female subjects 18-85 years old with a diagnosis of invasive breast cancer who are planned for anthracycline-inclusive chemotherapy and followed up for a time period of 6 months post completion of anthracycline chemotherapy. They will participate in blood and imaging tests with a goal of determining the best method for predicting the occurrence of cardiotoxicity in this subpopulation.
The primary objective of this study is to investigate whether giving prophylactic metoprolol prior to and during anthracycline or trastuzumab therapy will decrease the incidence of anthracycline-induced cardiomyopathy. Patients are randomized to receive metoprolol or no treatment prior to anthracycline or trastuzumab treatment. The ejection fraction, as measured by nuclear ventriculography is measured before and after treatment.
