Atrial fibrillation (AF) is common in dialysis patients. However, clinical characteristics and outcomes of dialysis patients with AF are poorly understood. The Fushimi AF Registry is a community-based prospective survey of AF patients in Japan. Follow-up data were available for 3713 patients with a median follow-up of 2.8 years. We compared clinical characteristics and outcomes between the dialysis group (n = 92; 2.5 %) and others. The dialysis group had more various co-morbidities, with a mean CHADS2 score of 2.5, and the rate of warfarin prescription was 38 %. The annual incidence rates of stroke or systemic embolism (SE), major bleeding, and all-cause death in the dialysis group were 4.0, 5.1, and 20.9 per 100 person-years, respectively. There was no significant difference in the incidence rate of stroke/SE between the dialysis group and the non-dialysis group [hazard ratio (HR) 1.74 (95 % confidence interval (CI) 0.74-3.42)]. The incidence rates of major bleeding, all-cause death, and the composite of stroke/SE and all-cause death in the dialysis group were higher than those in the non-dialysis group [major bleeding: HR 3.09 (95 % CI 1.46-5.72), all-cause death: HR 3.51 (95 % CI 2.48-4.81), the composite of stroke/SE and all-cause death: HR 2.99 (95 % CI 2.15-4.05)]. Among dialysis patients, warfarin did not affect major clinical events including stroke/SE, bleeding or all-cause death. Among AF patients, those receiving dialysis showed higher incidence of major bleeding and all-cause death compared with non-dialysis patients, but the risk of stroke/SE was not particularly high.
