Cardiooncology. Basic principles of prevention and treatment of cardiotoxicity in cancer patients

Abstract

Advances in the diagnostics and treatment of cancer have led to improved survival of patients and decreased mortality. Cardiovascular complications (CVC) however, are among the most frequent side effects of anticancer treatment, which can have an adverse effect on the prognosis. This may be the result of cardiotoxicity, which involves direct effects of the radiation therapy and /or chemotherapy on the heart function and structure. Heart failure with cancer therapy was associated with a 3.5-fold increase in the risk of mortality compared with idiopathic cardiomyopathy. The cardiotoxicity risk assessment is often difficult, due to the different susceptibility of patients to drugs and their combinations, and coadministration of radiation therapy. Therefore, the likelihood of development and the time of occurrence of cardiotoxicity may vary and not always depend on the initial risk. Strategies for managing such patients are in most cases based on the expert opinion. This article provides recommendations for the prevention and therapy of cardiotoxicity, set out in the consensus of the European Society of Cardiology 2016.
