Objective: To estimate the main indirect costs of heart failure (HF) in the Brazilian population, on the health system, social security cost, and how much is lost in productivity due to the complications of the disease. Methods: Ecological study developed with secondary data, for the historical series from 2018 to 2021, mined from the Department of Informatics of the Unified Health System (Datasus), from the Brazilian Institute of Geography and Statistics (IBGE), and social security indicators collected from Social Security and the National Social Security Institute (INSS). Results: There were 77,290 deaths from HF in Brazil for the period, evenly distributed according to sex. The mortality rate was diversified among Brazilian regions, with emphasis on the Southeast and Northeast. Projections indicate a total expenditure of more than BRL 1 billion with hospitalizations, with an average hospital cost of BRL 1,725.27 per person. The average cost per hospitalization exceeded BRL 2 billion. Approximately 3% of federal expenditures are earmarked for IC benefit payments. Of the total number of absences, 65% correspond to men and 35% to women, with costs that can reach R$ 6 billion lost per year.
