RESUMO
AIM: To evaluate the dynamics of LV global longitudinal strain (GLS) and other EchoCG parameters after high-dose chemotherapy (HDCT) and autologous hematopoietic stem cell transplantation (aHSCT). MATERIAL AND METHODS: The risk of LV dysfunction in patients after HDCT followed by aHSCT has not been sufficiently studied. This study included 74 patients with hemoblastosis aged 20 to 65 years who had undergone HDCT followed by aHSCT. All patients had a history of antitumor treatment. EchoCG with assessment of LV GLS and measurements of troponin T and N-terminal pro-brain natriuretic peptide (NT-proBNP) were performed for all patients before and after the treatment. RESULTS: A decrease in GLS by 15 % or more from the baseline was detected in 6 (8.1 %) patients. The decrease in GLS was associated with increased NT-proBNP >125âpg / ml at baseline (odds ratio, 8.667; 95 % confidence interval, 1.419-52.942; p=0.022). CONCLUSION: The decrease in LV GLS in patients after aHSCT was associated with increased NT-proBNP before the intervention.
