Background: Geriatric patients are at risk of atrial fibrillation (AF) and stroke, and the risk of oral anticoagulation (OAC) related bleeding is also presumed to be higher. Detailed knowledge about the prevalence of AF and bleeding pattern in this population is scarce. This study sought to assess the prevalence of AF, use of OAC, and the rate of major bleeding in geriatric patients who are prone to frequent falls. We expect to find a higher prevalence of AF among geriatric patients compared to elderly people of comparable age. Methods: This was an observational cohort study conducted at the Fall and Syncope Clinic. Inclusion criteria: age >65 years, availability of both electrocardiogram (ECG) and Holter registration. The use and reasons to withhold OAC and the rate of major bleeding were retrieved from the medical files. Results: A total of 428 patients with the mean age of 79.8 years were analyzed. The mean number of morbidities was 11 ±5. AF was known in 98 (23%) patients, first diagnosed in 10 (2%). Among them, AF was paroxysmal in 45 (45%) patients, and 50% of them were first diagnosed cases. Of patients with AF, 84% were using OAC. The rate of major bleeding episodes was 1.1 per 100 treatment years. Major bleeding episodes were not different between the patients using antiplatelet agents (APA), OAC, or no antithrombotic medication. Conclusions: In this geriatric population, 23% of patients had AF and almost half were paroxysmal. Compared to previous studies, the use of OAC has substantially increased to 84% and no differences were found in the rate of major bleeding episodes between those using APA, OAC, or no antithrombotic medication.
