The growing number of adult long-term cancer survivors has expanded our knowledge of negative physiologic sequelae associated with curative therapies. Of note are the cardiovascular corollaries of chest radiotherapy and some commonly used chemotherapy agents. A contemporary understanding of risk factors has facilitated the development of guidelines for prevention and surveillance of cardiac compromise. The future holds promise with enhanced opportunities to use cardioprotectant drugs and biomarkers to prevent and detect early myocardial changes. Infusion therapy nurses must keep abreast of these developments to facilitate their roles as patient educators and advocates in the face of this toxicity's prevalence.
