Background: To examine the subclinical myocardial injury shortly after epirubicin exposure in asymptomatic patients with large B-cell non-Hodgkin lymphoma using 2-dimensional (2D)speckle tracking echocardiography.

Methods: Sixty-seven patients aged 52.58 ± 13.86 years with large B-cell non-Hodgkin lymphoma treated with epirubicin were studied. Echocardiography was performed at baseline and 1 day after completion of the therapy. Global and regional longitudinal (LS), circumferential (CS) and radial strain (RS), standard deviation of time to peak LS (TLS-SD), CS (TCS-SD), RS(TRS-SD) were calculated using 2D speckle tracking echocardiography.

Results: Despite normal left ventricular ejection fraction, global LS (–18.30 ± 1.87% vs.–16.18 ± 1.92%; p < 0.01), CS (–20.37 ± 2.89% vs. –18.25 ± 2.40%, p < 0.01) and RS (39.95 ± 5.79% vs. 36.15 ± 5.79%, p < 0.01), were remarkably reduced compared to baseline values. However, TLS-SD, TCS-SD and TRS-SD showed no significant difference after epirubicin exposure. Hypertension was an independent predictor of reduction of global LS, CS and RS.

Conclusions: Subtle abnormalities in myocardial systolic function were present in asymptomatic patients shortly after anthracycline exposure, which could be detected by 2D speckle tracking echocardiography.
