Key result
Radiation causes injury to all components of the heart, including the vasculature, whereas anthracycline toxicity is generally limited to the myocardium.

Radiation and anthracyclines cause distinct patterns of cardiotoxicity, with radiation affecting all heart components and anthracyclines primarily affecting the myocardium, particularly in highly susceptible pediatric patients.
Radiation-induced heart disease (RIHD) and anthracycline cardiotoxicity are two patterns of cardiac dysfunction caused by therapeutic interventions to treat malignancies. They occur in both the pediatric and adult populations and there is evidence to suggest that pediatric patients are at greater risk. This is due in part to the longer survival rates but also reflects increased susceptibility to the attendant complications caused by both therapies. Radiation can cause injury to all the components of the heart, including the vasculature, while anthracycline toxicity is generally limited to the myocardium.

Berry et al. (2005) conducted a review in Radiation-induced heart disease and anthracycline cardiotoxicity. Radiation and anthracyclines was evaluated. Radiation causes injury to all components of the heart, including the vasculature, whereas anthracycline toxicity is generally limited to the myocardium.
