Anthracycline Cardiotoxicity in a Patient with Diffuse Large B-Cell Lymphoma: A Case Report

Cardiotoxicity is a relevant side effect of cancer therapy that leads to increased patient morbidity and mortality. It is fundamental to understand and remember it as a cause of disease since accurate and timely diagnosis is crucial. We present the case of a patient who developed chemotherapy-associated cardiac dysfunction after receiving treatment for a diffuse large B-cell lymphoma. Clinical history, echocardiography, and differential diagnosis led us to attribute her condition to heart failure (HF) due to early doxorubicin-induced cardiomyopathy. The patient outcome was favorable. We discuss the pathogenesis and incidence of anthracycline-induced cardiotoxicity as well as strategies for its detection, prevention, and treatment.
