Figure 1
Echocardiographic assessment before and after chemotherapy. (A) Baseline echocardiographic parameters reveal a left ventricular ejection fraction (LVEF) of 62.14% and an average global longitudinal strain (LV-GLS) of -20.19%. (B) 6 months post-chemotherapy demonstrates an LVEF of 61.87% and LV-GLS of -19.27%. (C) 12 months post-chemotherapy reveals a notable decline in cardiac function, with LVEF decreasing to 54.02% and LV-GLS to -15.18%. (D) Following 1 month of cardioprotective medication, there is evidence of improved cardiac function as indicated by an increase in LVEF to 56.59% and improvement in LV-GLS to -19.03%.
