OBJECTIVES: Hemodialysis patients have a higher incidence of stroke than healthy individuals. Hemodialysis patients living on remote islands are subject to additional distance and transportation difficulties. Therefore, we aimed to study the association between stroke and hemodialysis in patients living on remote islands.

MATERIALS AND METHODS: We conducted a retrospective cohort study based on the medical records of maintenance hemodialysis patients in Shinkamigoto-Cho, Nagasaki, Japan, between June 1, 2005, and June 31, 2022. The clinical characteristics, probability of hemorrhagic stroke, acute ischemic stroke-free rate, and survival probability with or without a history of anticoagulant/antiplatelet use were evaluated. The survival probability among the hemorrhagic stroke, acute ischemic stroke, and non-stroke groups was also evaluated.

RESULTS: This study involved 142 patients. Nine patients (6.3%) had intracerebral hemorrhage, one (0.7%) had subarachnoid hemorrhage, eight (5.6%) had acute ischemic stroke, and 124 (87.3%) had no stroke. The number of patients with severe disabilities (modified Rankin Scale 5/6) was significantly higher in the hemorrhagic stroke group. The probability of hemorrhagic stroke and acute ischemic stroke-free rate, or survival probability with or without a history of anticoagulant/antiplatelet use, were not significantly different. The acute ischemic stroke group was not associated with a lower survival probability than the other groups. The hemorrhagic stroke group had a significantly lower survival probability than the acute ischemic stroke group.

CONCLUSIONS: This is the first study to report the status of stroke in hemodialysis patients living on remote islands, thus providing valuable information for improved stroke management in such patients.
