Breast cancer is the most common cancer amongst Canadian women. 15-20% of early breast cancers have high levels of a protein called HER2 which is associated with worse survival. Treatment of these patients with anthracyclines followed by trastuzumab (which targets HER2) improves survival. Unfortunately, these medications together can cause heart muscle injury resulting in heart dysfunction or failure in about 14% and 3.6% of the patients, respectively. Once heart failure (HF) occurs, about 60% of patients will not live past 2 years. Studies have suggested that patients with heart injury caused by anthracyclines may be more likely to develop HF with addition of trastuzumab. Therefore tests to find early heart injury after anthracyclines may allow doctors to start heart protective medications with the hope of preventing HF. Also, animal and small patient studies have shown that an increase in the water levels of the heart muscle (edema) may be an early sign of heart injury from anthracyclines. Cardiac MRI is a unique technique that has been shown to detect edema in various heart diseases.

The investigators will test the theory that, in women receiving treatment for breast cancer, heart edema detected by MRI at the end of anthracyclines will identify patients who will later develop heart dysfunction. MRI studies with novel techniques will be done pre-therapy, after anthracyclines, during herceptin, and at end of all therapy. The investigators will compare patients with and without heart dysfunction to test if patients with heart dysfunction are more likely to have edema after anthracyclines. Ultimately the investigators hope to use cardiac MRI to identify high risk patients and study various heart protective medications to prevent HF. This will improve the personal health of cancer patients by allowing them to live free of heart disease after their cancer therapy. Ultimately at a population level this will allow doctors to provide care that can be uniquely designed for each patient based on their individual risk.

The first 136 patients enrolled are included in the first part of the study, named EMBRACE-MRI 1. Enrollment for this part of the study is complete.

The remaining 44 patients will be enrolled into EMBRACE-MRI 2, which includes slight differences in obtaining sequences in MRI imaging.

Evaluation of Myocardial Changes During BReast Adenocarcinoma Therapy to Detect Cardiotoxicity Earlier With MRI - The EMBRACE MRI Study

Myocardial edema is defined as an 8% increase in segmental T2 values measured in milliseconds in at least 2 myocardial segments at either of the 2 early time points. Cardiotoxicity is defined as Cardiac Magnetic Resonance Imaging (CMR) measured (1) ≥5% absolute reduction in Left Ventricular Ejection Fraction (LVEF) from baseline to an LVEF \<55% with signs or symptoms of HF, OR (2) a ≥10% absolute reduction in LVEF from baseline to \<55% without accompanying signs or symptoms at the time points when CMR is obtained OR (3) the same amount of reduction in LVEF as above, identified by echo at any time point (done every 3 months) and confirmed by CMR at that time.
