    Article - En anglais

    Background and Purpose Changes in stroke incidence are likely to occur as a consequence of aging of the population, but evidence for this hypothesis is lacking.

    Methods A prospective community-based registry of first-ever strokes (1994 to 1998) classified according to the International Classification of Diseases, 9th Revision (ICD-9) was established in the L'Aquila district, central Italy, with a total population of 297 838 (1991 census).

    Patients were identified by active monitoring of multiple sources, including general practitioners.

    Results In 1994,819 patients (398 men and 421 women ; mean±SD age, 74.8±11.3 years) suffered from a first-ever stroke.

    Eighty-nine percent of the patients had neuroimaging studies of the brain and were reclassified with the recent Application of the International Classification of Diseases to Neurology (ICD-10 NA).

    The occurrence of subarachnoid hemorrhage, intracerebral hemorrhage, cerebral infarction, and ill-defined events was 2.9%, 14.9%, 80.2%, and 2.0%, respectively.

    Crude annual incidence of first-ever stroke was 2.75/1000 (95% confidence interval [CI], 2.57 to 2.94) and 24.23/1000 (95% CI, 21.65 to 27.10) in patients older than 80 years.

    Incidence rates were higher in men and steeply increased with age.

    The standardized rate was 2.37/1000 for the Italian and 2.28/1000 for the European population.

    The 30-day case-fatality rate was 25.6% (95% CI, 22.8% to 28.7%). (...)
