Purpose Cardiotoxicity from anti-human epidermal growth factor receptor 2 (HER2) therapy carries a short-and long-term risk of incident heart failure and increased cardiovascular mortality in patients with breast cancer. Interruptions in anti-HER2 therapy due to cardiotoxicity can lead to suboptimal cancer treatment. The purpose of this narrative review is to outline opportunities to optimize cardiovascular care in patients with HER2-positive breast cancer to prevent interruptions in therapy. Methods This case-based review presents the current literature on evidence-based strategies for personalized cardiotoxicity risk assessment, risk mitigation interventions, cardiac function surveillance tools, and management of asymptomatic left ventricular dysfunction in breast cancer patients receiving anti-HER2 therapy. Results Pretreatment cardiac risk assessment incorporates both treatment-related risk factors and patient-related risk factors for the development of cardiac dysfunction. Prevention and monitoring strategies while on treatment utilize risk factor modification, imaging and biomarker surveillance. Management of asymptomatic left ventricular dysfunction due to anti-HER2 therapy is evolving. Permissive cardiotoxicity in asymptomatic patients while starting cardioprotective therapies requires close collaboration between oncology and cardiology, and referral to cardio-oncology if available. Conclusions Patient-centered, multimodal strategies to prevent, detect, and manage cardiotoxicity from anti-HER2 therapy are necessary to improve outcomes in patients with HER2-positive breast cancer.
3DPC-MRI parameters (D-F) are shown in Figure 1. Note less overall bias for the 3DPC-MRI technique. Conclusions Initial results in a small patient cohort support the hypothesis that 3DPC-MRI provides better estimation of hemodynamic parameters in AS patients in comparison to 1DPC-MRI.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
