What is cardiotoxicity? 

Cardiotoxicity is any sort of untoward effect on the heart that might damage the heart muscle, the heart lining, the heart blood vessels. We can see it sometimes with radiation therapy. We can see it sometimes from other causes, diseases. Basically anything that causes negative effects on the heart could be considered cardiotoxicity.


Cardiotoxicity is a negative side effect to the heart caused by radiation therapy, other treatments or certain diseases, Premier Physician Network (PPN) physicians say.

It can be a side effect of cancer treatments targeted near a cancer patient’s heart.

Though treatments are developed to help fight cancer, they also have the possibility of damaging the heart and leading to cardiovascular issues, according to the National Cancer InstituteOff Site Icon (NCI).
