The aim of our study was to prospectively monitor and analyze lipid metabolism abnormalities in de novo CML patients treated with NILO at the start and during the first year of tyrosine kinase inhibitors therapy and to compare the results with patients receiving IMA. We evaluated the association of these laboratory changes with the risk of future CV events, CV risk dynamics, and use of statins during tyrosine kinase inhibitors administration based on the European Society of Cardiology guidelines.
