Cancer incidence increases with age, and as life expectancy increases, the number of elderly patients with cancer is increasing. Cancer treatments, including chemotherapy and radiotherapy, have significant short- and long-term effects on cardiovascular function. These cardiotoxic effects can be acute, such as changes in electrocardiogram (ECG), arrhythmias, ischemia, and pericarditis and/or myocarditis-like syndromes, or they can be chronic, such as ventricular dysfunction. Anticancer therapies can also have indirect effects, such as alterations in blood pressure, or can cause metabolic abnormalities that subsequently increase risk for cardiac events. In this review, we explore both observational and clinical trial evidence of cardiac risk in the elderly. In both observational and clinical trial data, risk of cardiotoxicity with anthracycline-based chemotherapy increases with age. However, it is less clear whether the association between age and cardiotoxicity exists for newer treatments. The association may not be well demonstrated as a result of under-representation of elderly patients in clinical trials and avoidance of these therapies in this population. In addition, we discuss strategies for surveillance and prevention of cardiotoxicity in the elderly. In the elderly, it is important to be aware of the potential for cardiotoxicity during long-term follow-up and to consider both prevention and surveillance of these late effects.
