Chemotherapy-induced cardiotoxicity

Abstract

Cardiotoxicity is one of the most important side effects of first-line chemotherapy medications. It is influenced by genetic variation, whereby the relationship between the chemotherapeutic dose and the risk of cardiotoxicity can be altered. The incidence of cardiotoxicity depends on the substance used in the therapeutic modality of cancer and can reach an incidence of 30% during a three-year follow-up. The main element of the clinical picture is systolic dysfunction of the left ventricle, with symptoms of heart failure, which can change or stop oncological therapy, along with pharmacological treatment of heart failure. These symptoms can occur during prolonged use of cancer therapies, monitoring the patient is advisable. Considering the increasing success of oncology therapy and the extension of life, as well as the improvement of the quality of life, a multidisciplinary approach, as well as the symbiosis of the work of cardiologists and oncologists, is imperative. Patient stratification concerning oncological treatment modality is imposed as part of a cardiologist's daily work from the beginning of cancer treatment.
