The EMBRACE Study The EMBRACE Study

There is emerging cellular and experimental evidence that cardiac energetic status is reduced after anthracycline treatment, however, this has not been tested in the human heart. The researchers hypothesize that cardiac energetic status is reduced in the human heart after administration of anthracycline therapy in breast cancer patients, inline with the evidence available from all other types of cardiomyopathies. The researchers propose to use in vivo 31Phosphorus cardiac spectroscopy to measure the cardiac energetic status at the beginning and at the end of the cycles of chemotherapy in the hearts of breast cancer patients who are administered epirubicin (the most modern anthracycline to date) and compare this with the cardiac energetic status of age and gender matched healthy controls. Further, the researchers wish to explore if the myopathy-induced effect of anthracyclines extends to the skeletal muscle as well, by examining skeletal muscle biopsies in these patients.
