Background
Atrial fibrillation (AF) is the most frequent cardiac arrhythmia with an impact on morbidity and mortality found in the geriatric population.
Objective
This retrospective study is the first to investigate the prevalence, treatment and comorbidities of AF in a large cohort of older adults.
Material and methods
Older adults with AF hospitalized between 2010 and 2018. The mean age of the 10,700 AF patients in 2018 was 83.2 ± 6.4 years. The frequency of anticoagulation in older adults with AF between 2010 and 2018 was analyzed. The relationship between comorbidities and anticoagulation in 2018 was examined. Logistic regression analysis was used to identify possible predictive factors for anticoagulation.
Results
The prevalence of AF in 35,887 hospitalized older adults was 29.8% in 2018. The mean CHA2DS2VASc score was 4.4 ± 1.3 (male 3.8 ± 1.3, female 4.7 ± 1.2). From 2010 to 2018, the frequency of anticoagulation for patients with AF rose from 32.1% to 64.2%. Statistically significant differences in the examined characteristics between anticoagulated and not anticoagulated patients were found. Furthermore, there were no predictive factors for anticoagulation in multivariate logistic analysis.
Conclusion
Hospitalized older adults have an increased prevalence of AF compared to the general population. Despite the higher risk of bleeding, older adults were more frequently anticoagulated in the observation period, preferably with direct oral anticoagulants (DOACs). Patients without anticoagulation had more diagnoses and were worse in functional tests. This study suggests that the decision to give anticoagulants to older adults should be personalized.
