An evaluation of the cardiotoxicity of imatinib mesylate

We studied 103 consecutive patients with chronic myeloid leukaemia on treatment with imatinib (IM) and 57 patients with chronic myeloproliferative disorders not treated with IM in order to evaluate its cardiotoxicity. There was no statistical difference regarding cardiac symptoms and signs, BNP levels and echocardiographic measurements for IM and control groups, except for peripheral oedema, more frequent in the IM group. Four patients in the IM group presented a BNP level >100 pg/ml, one of them with depressed LVEF. IM was not related to systematic deterioration of cardiac function, but there is still a possibility of isolated cases of cardiotoxicity. (C) 2008 Elsevier Ltd. All rights reserved.
