Research progress of biomarkers in early detection of chemotherapy-induced cardiotoxicity.

With the advances of drug therapy, the prognosis of cancer patients has seen remarkable improvements, and cancer-related mortality has decreased significantly. However, the followed drug-related cardiotoxicity becomes a serious threat to patients' living quality and survival rate. Cardiovascular toxicity associated with some chemotherapy drugs is reversible and dose-dependent. If early identification is possible, early cardiovascular protection measures or adjustment of chemotherapy regimens can be taken to improve the prognosis of patients. Therefore, early prevention and monitoring of chemotherapy-related cardiotoxicity are critical for cancer patients and survivors. Among them, biomarkers are an important method for the early identification of myocardial injury.
