Purpose of review: Patients with cancer have an elevated risk of cardiovascular disease. This review describes the cardiovascular risks of different cancer therapies and the evidence for cardioprotective strategies.
Recent findings: Recent studies have provided additional support for the safety and efficacy of dexrazoxane and liposomal anthracycline formulations in certain high-risk patients receiving anthracyclines and for neurohormonal antagonist therapy in patients with breast cancer receiving sequential anthracyclines and trastuzumab. Ongoing studies are exploring the benefit of: (1) statins for anthracycline cardioprotection; (2) strict blood pressure control during vascular endothelial growth factor inhibitor treatment and; (3) dexrazoxane on long-term cardiac outcomes in pediatric populations. To date, there are no evidence-based cardioprotective strategies specifically for radiation-related heart and vascular disease, immunotherapy myocarditis, fluoropyrimidine cardiotoxicity, vascular endothelial growth factor inhibitor-related hypertension, BCR-Abl multikinase inhibitor vascular disease, and other established and emerging cancer therapeutics with cardiovascular effects. Current evidence supports specific cardioprotective strategies for high risk patients receiving anthracyclines or sequential anthracycline-trastuzumab therapy; however, major evidence gaps exist.
