Özet

Background: The aim of this study is to evaluate atrial involvement by comparing pre- and post-chemotherapy left atrial mechanical and electromechanical parameters in patients treated with cardiotoxic chemotherapeutic agents. Methods: We designed our study as a prospective cohort study. Sixty-eight female patients between the ages of 18 and 50, scheduled for treatment with cardiotoxic chemotherapeutic agents, were included in our study. Atrial mechanical functions and electromechanical parameters were examined and compared with basic echocardiographic parameters before and after chemotherapy. Results: The mean age of the patients was 41.6 +/- 7.9 years. After chemotherapy, lateral PA, septal PA, and tricuspid PA durations showed a significant increase (p < 0.001), but there were no statistically significant changes in the left intra-atrial electromechanical delay, the right intra-atrial electromechanical delay, or the interatrial electromechanical delay values. Following treatment, LAVmax, LAVmin, and LApreA significantly increased (p < 0.001). Additionally, the left atrial passive and active emptying volumes increased (p < 0.001), while the reservoir and pump (active emptying) functions decreased (with p-values of 0.03 and 0.01, respectively). The passive emptying function, however, showed no significant change (p = 0.65). Decreases in LVEF were observed, while LVEDD, LVESD, IVS, PW, and LA diameters increased (p-value of 0.02 for IVS and <0.001 for the others). Conclusions: Significant impairment of atrial mechanical functions and electromechanical parameters was observed after treatment with cardiotoxic chemotherapeutic agents. This suggests an elevated likelihood of atrial arrhythmia linked to the use of cardiotoxic chemotherapeutic agents.
