Assessment of biventricular systolic strain derived from the two-dimensional and three-dimensional speckle tracking echocardiography in lymphoma patients after anthracycline therapy

AbstractThe aim of this study was to investigate the usefulness of three-dimensional (3D) speckle tracking echocardiography (STE) for assessment of both left and right ventricular systolic function in patients with lymphoma after anthracycline chemotherapy, compared with two-dimensional (2D) STE. Totally eighty-nine patients undergoing anthracycline containing chemotherapy were studied. Echocardiographic assessment included 2D and 3D left ventricular (LV) global longitudinal strain (GLS), global circumferential strain (GCS) and right ventricular (RV) GLS. All the parameters were analyzed at baseline, after the completion of four cycles and at the end of the regimen respectively. The area under the receiver operating characteristic curve was calculated to determine the capability of various echocardiographic parameters to discriminate between before and after chemotherapy. Compared with those at baseline, the 3D GLS and GCS of LV and GLS of RV decreased significantly after four cycles of the therapy (all p  <  0.01). At the end of the treatment, 2D GLS and GCS of LV deteriorated markedly (both p <  0.05). The area under the curve for GLS, GCS of LV and GLS of RV derived by 3D were 0.81, 0.66 and 0.78, respectively. The cutoff value with −20.4% of LV GLS by 3D had sensitivity of 81% and specificity of 66% for differentiating patients after therapy from baselines. The cutoff value with −2 1.9% of RV GLS by 3D had sensitivity of 71% and specificity of 74% fordif...
