Identification and protection of early cardiotoxicity in acute myeloid leukemia patients undergoing transplantation

Cardiotoxicity of antitumor therapy results in declining survival rates. More specifically, cardiotoxicity is positively correlated with cumulative dose of anthracyclines and eventually develops from reversible to irreversible. In this context, early monitoring methods should be explored for the timely detection of cardiotoxicity and cardioprotective therapy should be performed in patients under consideration for potentially cardiotoxic therapy. This paper reports a 22-year-old male patient with acute myeloid leukemia who underwent whole-course cardiac monitoring after receiving antileukemia therapy. After the early detection of an asymptomatic decrease in left ventricular ejection fraction (LVEF), along with a significant decrease in global longitudinal strain (GLS), the patient was treated with sacubitril/valsartan (Sac/Val). Finally, the patient completed four courses of chemotherapy and subsequent hematopoietic stem cell transplantation as planned. The measurements of LVEF and GLS also recovered after 2 months treatment of Sac/Val. Therefore, the early identification and protection of patients with cardiotoxicity are of paramount importance and future prospective studies are expected to develop the management and treatment of cancer treatment-related cardiac dysfunction.
