Abstract

Background: Our aim was to investigate the baseline clinical and echocardiographic parameters for predicting left ventricular (LV) dysfunction after anthracycline chemotherapy and heart failure (HF) hospitalization in a single cancer disease.

Methods and Results: We studied 73 patients with malignant lymphoma and preserved LV ejection fraction (LVEF). Echocardiography was performed before and after anthracycline chemotherapy. Global longitudinal strain (GLS) was determined from 3 standard apical views. LV dysfunction after anthracycline chemotherapy was defined according to the current definition of cancer therapeutics-related cardiac dysfunction. Long-term (50-month) unfavorable outcome was prespecified as hospitalization for HF. A total of 10 patients had LV dysfunction after anthracycline chemotherapy. Multivariate logistic regression analysis showed that baseline GLS was the only independent predictor of this dysfunction. Receiver-operating characteristic curve analysis identified the optimal GLS cutoff for predicting LV dysfunction after anthracycline chemotherapy as ≤19% (P=0.008). Furthermore, the Kaplan-Meier curve indicated that fewer patients with GLS >19% were hospitalized for HF than among those with GLS ≤19% (log-rank P=0.02). For sequential logistic models, a model based on baseline clinical variables (χ2=2.9) was improved by the addition of baseline LVEF (χ2=9.0; P=0.01), and further improved by the addition of baseline GLS (χ2=13.1, P=0.04).

Conclusions: Watchful observation or early therapeutic intervention with established cardioprotective medications may be necessary for patients with malignant lymphoma and preserved LVEF but with abnormal GLS.
