Abstract
This article addresses cardiotoxicity in patients with breast cancer who are treated with anthracyclines and/or anti-human epidermal growth factor 2 (HER2) therapy, namely doxorubicin and trastuzumab. Development of concise clinical guidelines for chemotherapy-induced heart failure is ongoing. Through identification of specific risk factors and clinical predictors of cardiotoxicity, clinicians are able to better understand and define effective monitoring strategies and optimize patient care. Close cardiac monitoring is recommended for patients throughout treatment with anthracyclines and anti-HER2 therapy. Pretreatment risk assessment with echocardiography and evaluation of cardiovascular risk factors aid in predicting the development of left ventricular (LV) dysfunction. Further clinical trials are needed to increase understanding and optimize treatment guidelines for LV dysfunction in patients taking anthracyclines or anti-HER2 therapy.
