Event, incidence, and fatality rates of cerebrovascular diseases in Enköping-Håbo, Sweden, 1986-1988

Abstract

In order to study the need for medical care among elderly stroke patients, a prospective registration of cerebrovascular diseases started on January 1, 1986 in Enköping-Håbo health service district, Sweden. This article reports the design of the stroke register and the registration procedures, the annual events of stroke, both first-ever and recurrent, during 1986 - 1988 and the fatality rate with special regard to the very old population. The annual incidence of first-ever stroke was 0.33/1,000 among persons younger than 65 years of age, 10.6/1,000 among persons aged 65-84 years, and 34.5/1,000 among persons aged 85 years and older. The fatality rate of first-ever strokes was 7.5% within one month for persons younger than 65 years of age, 20.3% in the age-group 65-84 years, and 41% for the population 85 years and older. These results are compared with a similar Swedish study from Söderhamn and four comparable international studies. The results from this study gave a basis for designing special care programs in hospital and in home-care also for old stroke patients.
