The purpose of this study is to assess the predictive role of Pulsed-waved TDI in predicting cardiotoxicity in breast cancer patients. In total, 270 breast cancer patients, 27 of whom experienced CTRCD during the follow-up period, were enrolled. Echocardiography was performed at baseline (before the beginning of the treatment), and TDI images were obtained. Other clinical variables were also measured. Significant differences were found between the TDI images of patients who developed cardiotoxicity and those of patients who did not, particularly around the <jats:inline-formula>\n              <jats:tex-math>$$\\:{E}^{{\\prime\\:}}$$<\/jats:tex-math>\n            <\/jats:inline-formula> wave.
