Area of Science:

  • Neurology
  • Epidemiology
  • Public Health

Background:

  • A prospective stroke registry was established in Malmö, Sweden, in 1989.
  • The registry aimed to monitor stroke incidence, recurrence, and fatality rates in a population of 232,000.

Purpose of the Study:

  • To prospectively follow up stroke incidence, recurrence, and fatality rates.
  • To assess the epidemiology of stroke in Malmö.
  • To validate the utility of a stroke registry for research.

Main Methods:

  • Patients with presumed stroke were interviewed within one week of hospital admission.
  • Medical records were examined, and continuous validation against hospital diagnoses ensured high case ascertainment (>90%).
  • Stroke diagnostic categories included subarachnoid hemorrhage, intracerebral hemorrhage, cerebral infarction, and unspecified stroke.

Main Results:

  • Overall stroke incidence was 300 per 100,000 residents, with first-ever stroke at 225 per 100,000.
  • Cerebral infarction was the most common diagnosis (50%), followed by unspecified stroke (38%).
  • Major risk factors identified were prior stroke, hypertension, smoking, atrial fibrillation, and diabetes mellitus. The 30-day case-fatality rate was 15%, with higher rates for intracerebral hemorrhage (37%) than cerebral infarction (10%).

Conclusions:

  • The study confirms the value of a stroke registry for epidemiological research.
  • Stroke registries are essential tools for understanding stroke patterns and outcomes.
  • Findings provide valuable data on stroke incidence, risk factors, and case-fatality in the studied population.
