Summary

Neoplasia is the main cause of general death in the Brazilian population. In 2016, they were responsible for approximately 211,343 (16%) deaths, followed by cardiovascular diseases (12.6%). Despite the high mortality rate of neoplasia, oncological treatment have advanced substantially in recent decades improving the prognosis of patients. However, growing evidence suggest that some oncological agents may induce significant toxicity that may play a major role in the quality of life, morbidity and mortality. The cardiovascular system is often negatively affected with cancer therapy, predisposing several patients to stop appropriate treatments or to have cardiovascular events related to the cardiotoxicity. The most typical manifestation of cardiotoxicity and related consequences (heart failure) are related to the use of anthracyclines. Anthracyclines are part of the chemotherapy regimen for solid tumors and hematological neoplasms in children and adults, and are associated with an increase in life expectancy. Carvedilol is an α and β-blocker that also has antioxidant properties. Preliminary studies have shown that carvedilol and its metabolites prevent lipid peroxidation, inhibit the formation and inactivate free radicals, in addition to preventing the depletion of endogenous antioxidants, such as vitamin E. These effects would potentially prevent anthracycline injury but definitive evidence is still needed. This is a multi-center, double-blind, randomized, placebo-controlled study that aims to establish the efficacy of carvedilol for the primary prevention of left ventricular systolic dysfunction in cancer patients obtained with anthracycline chemotherapy, in different schedules and doses.
