About this trial
Due to a risk of heart failure during HER2 directed therapy in breast cancer, treatment is monitored with imaging of myocardial function, which is resource demanding for both patients and the health care system. The purpose of this study is to evaluate, if biomarkers can replace imaging based examinations of myocardial function during HER2 directed therapy.
