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.
