Correlation between Melphalan chemotherapy with longitudinal global strain indices of the left ventricle in multiple myeloma patients: a velocity vector imaging (VVI) echocardiography study

Abstract

Multiple myeloma (MM) is characterized by the neoplastic proliferation of plasma cells, leading to the production of monoclonal immunoglobulins. High-dose chemotherapy with autologous stem cell transplant has been used in the treatment of patients with MM (1). Melphalan (L-phenylalanine nitrogen mustard) is one of the most effective chemotherapeutic drugs in the treatment of MM (2). The side effects of melphalan include anemia, nausea, vomiting, allergic reactions, oral ulcers, nephrotoxicity, and arrhythmia at high doses (3). The effect of this drug on cardiac mechanics and heart damage is not well established, as previous studies have only focused on the electrocardiographic and metabolic effects of this drug.
