Background and Purpose In Norway, as well as other industrialized countries, mortality from stroke has declined over the past decades.
Data on stroke morbidity are lacking.
This study was conducted to determine the incidence, case fatality, and risk factors of stroke in a defined Norwegian population.
Methods During the period 1994 to 1996, a population-based stroke registry collected uniform information about all cases of first-ever and recurrent stroke occurring in people aged =15 years in the region of Innherred in the central part of Norway (target population 70 000), where the prevalence of cardiovascular risk factors was screened in 1984 to 1986 and 1995 to 1997.
Results During the 2 years of registration (September 1,1994, to August 31,1996), 432 first-ever (72.8%) and 161 recurrent (27.2%) strokes were registered.
The crude annual incidence rate was 3.12/1000 (2.85/1000 for males and 3.38/1000 for females).
Adjusted to the European population, the annual incidence rate of first-ever stroke was 2.21/1000.
The annual incidence rate of cerebral infarction was 2.32/1000, intracerebral hemorrhage 0.32/1000, subarachnoid hemorrhage 0.19/1000, and unspecified stroke 0.38/1000.
The 30-day case-fatality rate was 10.9% for cerebral infarction, 37.8% for intracerebral hemorrhage, and 50.0% for unspecified stroke. (...)
