title: Stroke Incidence and Survival in Ludwigshafen am Rhein, Germany: the Ludwigshafen Stroke Study (LuSSt).
abstract: OBJECTIVE
  Considerable locoregional differences in stroke incidence exist even within countries. Based on data from a statewide stroke care quality monitoring project, we hypothesized a high stroke incidence mainly among younger age groups in the industrial city of Ludwigshafen am Rhein, Germany. To test this hypothesis and to provide data on stroke incidence and case-fatality rates, a population-based stroke register was initiated.
  
  
  METHODS
  The Ludwigshafen Stroke Study is a prospective ongoing population-based stroke register among the 167 906 inhabitants of Ludwigshafen am Rhein. Starting on January 1, 2006, standard definitions and multiple overlapping methods of case ascertainment were used to identify all patients with incident stroke or transient ischemic attack.
  
  
  RESULTS
  In 2006 and 2007, 1231 cases with stroke or transient ischemic attack including 725 patients with first-ever stroke were identified. The crude annual incidence rate per 1000 for first-ever stroke was 2.16 (95% CI 2.10 to 2.32). After age adjustment to the European population, incidence for first-ever stroke was 1.46 (95% CI 1.35 to 1.57; men: 1.63; 95% CI 1.46 to 1.81; women: 1.29; 95% CI 1.15 to 1.43). Crude annual incidence rates per 1000 were 1.86 for ischemic stroke, 0.19 for intracerebral hemorrhage, 0.05 for subarachnoid hemorrhage, and 0.05 for undetermined stroke. Case-fatality rates for first-ever stroke were 13.6%, 16.4%, and 23.2% at Days 28, 90, and 365, respectively.
  
  
  CONCLUSIONS
  High crude incidence rates in our study reflect the rising burden of stroke in our aging population. Age-adjusted incidence rates were somewhat higher than those reported by recent studies from Western Europe, mainly due to higher incidence in subjects <65 years.
