| Popis: | CHOP chemotherapy (cyclophosphamide, doxorubicin, vincristine, prednisone) in non-Hodgkin lymphoma (NHL) is limited by risk of cardiotoxicity. Aim. To define new parameters to detect late cardiotoxicity. Methods 64 patients (27 men, 59±11 years) with NHL, scheduled for CHOP, with LVEF>50%, were assessed at baseline, after chemotherapy ended and 1 year later, by 3D echo for LVEF and deformation (longitudinal, radial, circumferential, area strain: LS, RS, CS, AS), by echo-tracking for pulse wave velocity (PWV) and wave intensity (WI), and by troponin I and NTproBNP. Cardiotoxicity was defined as LVEF decrease10% from baseline. Results 10 patients (group I) developed late cardiotoxicity, while 54 patients did not (group II). There was a reduction of LS, CS, AS, and increase of PWV and WI, with greater changes in group I (table). LVEF decrease correlated with LS, CS, AS, PWV, WI, troponin changes (r=0.57, r=0.37, r=0.41, r=−0.53, r=−0.43, r=−0.34 p22% at the end of treatment predicted late cardiotoxicity with 85% sensitivity and 74% specificity.
