Abstract

Background: Patients with cancer treated with chemotherapy are at risk for cardiovascular toxicity. Global longitudinal strain has been reported to play important roles in predicting cardiovascular adverse events (CAEs) in patients treated with anthracycline. In addition to various left ventricular indicators, the authors hypothesized that right ventricular (RV) parameters might be associated with CAEs related to anthracycline treatment.

Methods: In this retrospective study, 96 patients diagnosed with diffuse large B-cell lymphoma who received chemotherapy (cyclophosphamide, doxorubicin, vincristine, and prednisone plus rituximab) were studied using three-dimensional transthoracic echocardiography. Baseline demographic data and oncologic and echocardiographic parameters were analyzed. The main outcome was the proportion of patients with grade 3 to 5 CAEs. The association of all three-dimensional transthoracic echocardiographic parameters with long-term CAEs was analyzed using Cox proportional-hazard analysis.

Results: Over a median follow-up period of 6.1 years (range, 4.9-7.6 years) after the completion of anthracycline chemotherapy, 18 of 96 patients (19%) experienced CAEs. Percentage changes (%Δ) in left ventricular global longitudinal strain (LVGLS), global circumferential strain, RV ejection fraction (RVEF), and RV end-systolic volume were associated with CAEs (P < .05). A relative reduction of RVEF (hazard ratio, 0.847; 95% CI, 0.785-0.915; P < .001) was the strongest associated factor for CAEs. An increase in CAEs was also observed in patients with impaired %ΔLVGLS > 15% and impaired %ΔRVEF > 12.7% compared with those with impaired %ΔLVGLS > 15% and impaired %ΔRVEF < 12.7% (P = .032).

Conclusions: Three-dimensional echocardiography-based assessments of %ΔRVEF and %Δ in RV end-systolic volume were significantly associated with CAEs in patients with lymphoma treated with anthracycline chemotherapy.
