The present invention provides methods for treating cardiotoxicity, cardiomyopathy, and/or cancer in a subject, as well as related compositions and kits, that employ a therapeutic agent, or a nucleic acid sequence encoding a therapeutic agent, selected from apolipoprotein A-1 (ApoA1), an ApoA1 mimetic, an agent that increases expression of ApoA1, or a binding agent specific for oxidized ApoA1, where the therapeutic agent is effective in preventing or reducing the level of cardiotoxicity and/or cardiomyopathy induced by the chemotherapeutic.
