[Cardiovascular management of patients with chronic myeloid leukemia treated with BCR-ABL tyrosine kinase inhibitors: it is time for a shared management]

: Chronic myeloid leukemia is a rare myeloproliferative disease, characterized by a chromosomal translocation detected in 95% of cases, defined as "Philadelphia chromosome", encoding for the BCR-ABL fusion protein with continuous activation of the tyrosine kinase domain. Over the last 20 years, treatment has been revolutionized by the use of BCR-ABL tyrosine kinase inhibitors (TKI). Imatinib is the first TKI approved with a good cardiovascular safety profile, while some second-generation (nilotinib and dasatinib) and third-generation (ponatinib) drugs, developed to overcame drug resistance, can be associated with cardiovascular adverse events. The major adverse effect of dasatinib is pulmonary hypertension, reversible after treatment discontinuation. Conversely, nilotinib or ponatinib assumption is associated with a higher incidence of ischemic events, including coronary artery disease, cerebral stroke and peripheral arterial disease. Therefore, the management of patients receiving TKI therapy should include an integrated multidisciplinary evaluation and follow-up, involving highly specialized figures such as a cardiologist, hematologist and/or oncologist and the application of dedicated pathways, in order to prevent the onset or manage cardiovascular complications associated with these drugs.
