- Background/Introduction: Atrial fibrillation (AF) affects 7.3–13.7% of community-dwelling patients aged 80 years or older. AF is related to a wide panel of complications among which an augmented risk of mortality, hospitalization, stroke, and heart fail- ure as well as cognitive decline. Intra-hospital prevalence and impact of those complications are not well-described in the elderly. Purpose: This study aims to analyse the prevalence of AF among patients older than 74 years and its association with intra- hospital death. Methods: Anonymized medical data from 7653 hospitalization stays of patients 75 years and older between 01/01/2019 to 31/ 12/2019 were extracted from the central ‘minimal medical summary’ from Jolimont Hospital. To consolidate data, variables were also extracted from the medical history from medical files. Results: Among 7670 hospital stays of patients 75 years and older, 671 (8.7%) deaths were recorded among which 324 (48%) had atrial fibrillation. AF was recorded in a total of 2492 (38%) hospital stays among which 324 (324/2492, 11%) deaths were recorded. Among studied variables, Age, Atrial Fibrillation, Hypertension, Oncologic diagnosis, and heart failure were strongly associated with mortality (p < 0.001). After adjusting for age and heart failure, AF remained significantly associated with in-hos- pital death (p 1⁄4 0.017, OR 1.23). Conclusion(s): This pilot study reports a very high prevalence of AF at 38.35%. Near half (48%) of the recorded deaths were concomitantly recorded with atrial fibrillation whereas the mortality rate during hospital stay among patients with atrial fibrilla- tion was 11.01%. The difference between the mortality rate of hospitalized patients with AF and without AF (11.01 vs. 7.34, p < 0.0001) was highly significant. AF was significantly related to in-hospital mortality even after adjusting for HF and age.
