Breast cancer treatment methods have improved significantly, increasing patient survival rates. However, cardiovascular diseases are now the main cause of death in oncological patients, as cardiovascular complications caused by commonly used oncological treatments are a significant issue. Anthracyclines are incorporated into schemes of breast cancer (BC) chemotherapeutic treatment: HER2-positive, HER2-negative, and triple-negative BC subtypes, but the cardiotoxicity they cause needs to be taken into consideration. If a patient experiences this complication, heart failure is treated with pharmacological intervention following the European Society of Cardiology guidelines. A 38-year-old woman’s case highlights the complexity of making treatment decisions in this group of patients because she developed heart failurewith reduced left ventricular ejection fraction due to chemotherapy treatment.
