Conclusion
In summary, the study showed that using 2D GLS, RT-3DE, and 3D strain to calculate GLS, GCS, GRS, GAS could detect earlier myocardial dysfunction by chemotherapy. And the apical segments of the left ventricle seem to be more susceptible to cardiotoxicity. This provides a new direction for the study of anthracycline myocardial injury, for early myocardial toxicity detection is more accurate to a certain myocardial segment, more targeted timely and effective prevention and treatment.
