Prognostic value of acute kidney injury in stroke patients

The development of acute kidney injury (AKI) in stroke patients is associated with an increase in hospital mortality, period of hospital treatment, disability, and economic health costs. At the same time, the influence of AKI on long-term stroke outcomes remains unclear. The aim of the study was to determine the prognostic value of acute kidney damage in stroke patients. Materials and Methods. The authors examined 272 stroke patients. Acute kidney damage was established according to the KDIGO recommendations (2012). Mortality of stroke patients during hospital treatment was 20.6 %. The prospective follow-up of stroke patients discharged from the hospital was 12 months. Results. Acute kidney injury was diagnosed in 89 (32.7 %) stroke patients. After discharging from the hospital, 45 (20.8 %) patients died within 12 months. The relative risk of death within 12 months after stroke in the group of AKI patients was 3.7 (95 % CI 2.2-6.2, p
