Although XRT enhances cancer survival rates, it may also expose healthy bystander tissues to radiation, potentially leading to severe complications. Initially considered relatively resistant to radiation damage, the heart has been shown over the past 4 decades to be susceptible to radiation-induced cardiovascular toxicity and despite advances in XRT which can minimize radiation exposure to heart tissue, no cardiac radiation dose is entirely safe. The clinical spectrum of radiation-induced cardiovascular toxicity is broad, encompassing coronary artery disease, myocardial dysfunction, valvular abnormalities, and pericardial disorders. Radiation-induced cardiovascular toxicity may manifest acutely or many years after XRT, with each condition more likely to present at certain time points post-XRT.
