cardiotoxins
Cardiac-damaging toxic substances
Cardiotoxins are substances that damage the heart muscle or disrupt cardiac function.
Some snake venoms contain cardiotoxins that can cause heart failure.
Certain chemotherapy drugs have cardiotoxic effects, requiring careful monitoring during cancer treatment.
The term covers any agent—natural or synthetic—that poses specific danger to the heart: The oncologist weighed the cardiotoxins in the treatment protocol against the cancer's aggressiveness.
