Introduction: The causal relationship between atrial fibrillation (AF) and chronic heart failure is reciprocal, both emerging as new cardiovascular epidemics. Objectives: To identify clinical variables associated with the development of acute heart failure (AHF) in individuals with AF. Method: An observational and retrospective design was carried out on a database that included all individuals hospitalized for AF between 2021 and 2022. Their characteristics were described and presentation variables predictive of AHF were identified from a multivariable analysis. Results: 252 subjects, 67% male with a median age of 67 years (IQR 59-74). A history of heart disease was known in 19%, and AF was classified as paroxysmal in 41%, while it was persisten or permanent in 59%. Age (OR: 1,06; 95%CI: 1,02-1,10; p = 0,004) and previous history of heart disease (OR: 2,5; 95%CI: 1,1-5,6; p = 0,03) were identified as predictors of development of AHF. A higher rate of rehospitalization for heart failure was observed at follow-up (9 vs. 1%; p = 0,02; median time to rehospitalization of 4 months [RIC 2-8]). Conclusions: We identified age and history of structural heart disease as predictors of AHF in individuals hospitalized for AF. We observed in this group a higher rate of heart failure rehospitalization.
