Breast cancer is a group of diseases with a high incidence in the Brazilian population and its treatment involves the use of cardiotoxic antineoplastics. This work aims to analyze cardiotoxicity in patients with human epidermal growth factor receptor type 2 breast cancer undergoing treatment with trastuzumab at the oncology outpatient clinic of the Hospital Regional de Taguatinga – Federal District, through a cross-sectional study in the period between January from 2022 to December 2022, using the Left Ventricular Ejection Fraction values before and during antineoplastic treatment. In addition, information such as age, comorbidities and harmful habits were also verified to create a profile of the patients. 34 patients were included in the research, all of whom were female, with a predominance of age under 60 years and brown/yellow color/race. Regarding clinical characteristics, the majority of patients did not have other comorbidities and did not use new lifestyle habits, with only three having a reduction in the value of the Left Ventricular Ejection Fraction ≥ 16% and among these, two with lower values to 55%. In general, breast cancer treatment can result in cardiotoxicity, and this adverse effect is present in patients undergoing treatment at the Taguatinga Regional Hospital.
