Comparative Study[Trends in stroke incidence and case-fatality rates over a 20-year period (1985-2004) in Dijon, France].
With progress in stroke prevention it is important to evaluate epidemiological trends over a long period and in an unselected population. We estimated changes in stroke incidence, the case-fatality rate, risk factors, and the use of primary prevention, based on a continuous registry of a well-defined population, from 1985 to 2004. We recorded 3142 ischemic strokes, 341 primary cerebral hemorrhages and 74 subarachnoid hemorrhages. ⋯ The frequency of pre-stroke antiplatelet and anticoagulant treatment increased significantly (p < 0.01). The age - and sex-adjusted incidence rates of stroke in Dijon, France, have thus been stable for the past 20 years. Age at stroke onset has increased, the case-fatality rate has fallen, antiplatelet treatment is more frequent, and the frequency of some pre-stroke risk factors has fallen.
