Objectives:
In our study, we aimed to identify early markers of cardiac dysfunction in patients treated with mitoxantrone. We also looked at cardiac functional changes during therapy by analyzing longitudinal deformation and by measuring left ventricular (LV) and left atrial (LA) global strain.
Materials And Methods:
LA and LV global longitudinal strain were analyzed in 20 patients affected by multiple sclerosis and treated with mitoxantrone. Patients underwent echocardiography before treatment, after every drug administration during the 12-months treatment period, and finally after 6 and 12 months of drug discontinuation.
Results:
Compared with baseline values, patients showed a significant reduction of both LA and LV longitudinal global strain at the end of treatment with mitoxantrone (LA_GS% T10 vs. T0 values: 15,2 ± 12,5 vs. 20,2 ± 11,1; LV_GS%: ─16,4 ± 2,5 vs. ─17,4 ± 3,8). Strain reduction reverted after treatment discontinuation (LA_GS% FU vs. T0 values: 20,4 ± 15,7 vs. 20,2 ± 11,1; LV_GS%: ─17,3 ± 3,3 vs. ─17,4 ± 3,8).
Conclusions:
Impairment of longitudinal deformation during mitoxantrone therapy may indicate a dysfunction related to early myocardial damage. These findings appear to be reversible after treatment discontinuation.
