Abstract
Background: Brazil is a country with different biomes and social disparities. There are limited data available on regional differences and prognosis of heart failure (HF) in the country.
Objective: The Rosa dos Ventos study aims to investigate regional differences and the current prognosis of HF outpatients with reduced or mildly reduced ejection fraction in Brazil.
Methods: This is a prospective, multicenter, observational cohort study that will include outpatients older than 18 years with HF and an ejection fraction < 50% in 30 public and private centers distributed in all Brazilian regions. A total of 2,500 patients will be enrolled from June 2021 and October 2023, with a 12-month follow-up period. We will collect data on socioeconomic and clinical status, medical prescription and results of cardiology tests. Follow-up phone calls will be made at 6 and 12 months after inclusion to collect information regarding emergency room visits, hospitalization and mortality.
Conclusion: The Rosa dos Ventos study will allow a more accurate characterization of chronic HF in Brazil. This initiative will provide relevant information for the development of effective management strategies to mitigate the impact of this condition on patients and the healthcare system.
