High stroke incidence in the prospective community-based L'Aquila registry (1994-1998). First year's results.

摘要: Background and Purpose Changes in stroke incidence are likely to occur as a consequence of aging the population, but evidence for this hypothesis is lacking. Methods A prospective community-based registry first-ever strokes (1994 1998) classified according International Classification Diseases, 9th Revision (ICD-9) was established L’Aquila district, central Italy, with total population 297 838 (1991 census). Patients were identified by active monitoring multiple sources, including general practitioners. Results In 1994, 819 patients (398 men 421 women; mean±SD age, 74.8±11.3 years) suffered from stroke. Eighty-nine percent had neuroimaging studies brain reclassified recent Application Diseases Neurology (ICD-10 NA). The occurrence subarachnoid hemorrhage, intracerebral cerebral infarction, ill-defined events 2.9%, 14.9%, 80.2%, 2.0%, respectively. Crude annual 2.75/1000 (95% confidence interval [CI], 2.57 2.94) 24.23/1000 CI, 21.65 27.10) older than 80 years. Incidence rates higher steeply increased age. standardized rate 2.37/1000 Italian 2.28/1000 European population. 30-day case-fatality 25.6% 22.8% 28.7%). death, disability, full recovery at 1 year 36.9%, 38.9%, 24.2%, No differences found income urban or rural residences. Conclusions our population-based study, we high notably age subgroups, suggesting that rather declining, only being postponed until later life.
