Cardiotoxicity, a common complication of chemotherapy, may have irreversible adverse effects on the heart. Anthracycline-based chemotherapy for breast cancer can lead to dilation-hypokinetic cardiomyopathy, eventuating in heart failure. As the primary diagnostic tool for cardiovascular toxicity, echocardiography may be essential in evaluating the heart function of such patients.


This study aimed to identify the most important echocardiography findings for proper and timely diagnosis of cardiotoxicity in patients with HER2-positive breast cancer undergoing anthracycline-based chemotherapy.


Our final analysis included 132 female patients who were HER2-positive and had breast cancer. All of these patients had one pre-chemotherapy echocardiography and at least one echocardiography after three episodes of anthracycline-based chemotherapy. The patients’ age, body mass index, and history of chemotherapy were recorded. Mean alterations from baseline echocardiography to echocardiography after three episodes of chemotherapy were calculated for all parameters evaluated. Data analysis was conducted using the Statistical Package for the Social Sciences v. 26.


Significant changes were seen in three-dimensional left ventricular ejection fraction (LVEF 3D), two-dimensional left ventricular ejection fraction (LVEF 2D), left ventricular global circumferential strain (LVGCS), left ventricular global longitudinal strain (LVGLS), left ventricular end-diastolic volume (LVEDV), stroke volume (SV), left ventricular end-systolic volume (LVESV), right ventricular end-systolic dimension (RVESD) in patients with breast cancer (P < 0.0001). RVESD, LVESV, LVEDV, and SV significantly increased after three chemotherapy episodes, but LVEF (3D and 2D), absolute LVGCS, and absolute LVGLS fell significantly.


LVEF (3D and 2D), LVGCS, LVGLS, LVEDV, LVESV, SV, and RVESD are important echocardiography parameters in diagnosing cardiotoxicity in patients with HER2-positive breast cancer.
