Final answer:
Chemotherapy-induced cardiomyopathy is the development of heart muscle damage as a side effect of chemotherapy treatment. The heart muscle can be affected by chemotherapy drugs due to their impact on rapidly dividing cells, leading to weakened heart function.
Step-by-step explanation:
Chemotherapy-induced cardiomyopathy refers to the development of heart muscle damage as a side effect of chemotherapy treatment. Chemotherapy drugs are designed to target rapidly dividing cells, which includes both cancer cells and healthy cells with high turnover rates, such as those in the heart muscle. The damage to the heart muscle can lead to cardiomyopathy, which is a condition characterized by a weakened heart and reduced ability to pump blood effectively.
