Long-term survival after stroke in Lithuania: Data from Kaunas population-based stroke registry (original) (raw)

Background There is a lack of reliable epidemiological data on long-term survival trends of first-ever stroke patients in Lithuanian population. Aims To evaluate trends in long-term survival after stroke and to determine the influence of some sociodemographic and lifestyle factors, time and subtype of stroke, and stroke care on survival. Methods All stroke events included in Kaunas stroke register database were ascertained and validated according to the standardized criteria outlined by the WHO MONICA Project. The study included all patients in Kaunas (Lithuania) city aged 25 to 64 years who experienced a stroke between 1986 and 2011. Death time was confirmed by the Office for National Death Statistics. Estimates of stroke long-term survival data and factors influencing survival changes were made by applying the Kaplan-Meier and Cox regression analysis. Results During the study period, 4,129 persons aged 25-64 years suffered from a first-ever stroke: 2,215 (53.6%) of them were men and 1,914 (46.4%)-women. Ischemic stroke was significantly more frequent in males than in females (80.6% and 78.6%, respectively, p<0.05) and subarachnoid hemorrhage was more common in women than in men (9.0% and 7.0% respectively, p <0.05). Of all first-ever stroke patients, 3,272 (79.2%) survived 1 year and 2,905 (70.4%) survived 5 years after stroke onset. The 1-and 5-years survival rate after a
