Subtypes of ischemic stroke : A Hospital-based Stroke Registry in Taiwan (SCAN-IV).
Background and Purpose To better understand the clinical pattern and further elucidate the risk factors and outcome in different subtypes of cerebral infarction (CI) of the Chinese in Taiwan, we analyzed the National Taiwan University Hospital Stroke Registry in 1995 and performed an ethnic comparison with similar data banks.
Methods From the National Taiwan University Hospital Stroke Registry in 1995,676 patients (383 men and 293 women ; mean age, 64.9 years ; SD, 13.8 years ; range, 1 to 98 years) with CI were recruited for this analysis.
CI was classified into five subtypes based on clinical manifestations, ultrasonographic studies, and neuroimaging findings : large-artery atherosclerosis, lacunae, cardioembolism, other less common determined causes, and undetermined cause.
Vascular risk factors, extracranial carotid artery atherosclerosis, and 30-day case-fatality rates were investigated in each subtype of CI.
Results Of all CI patients, 17%, 29%, 20%, 6%, and 29% were classified as large-artery atherosclerosis, lacunae, cardioembolism, other determined causes, and undetermined cause subtypes, respectively.
The present results were compared with those from eight similar Western stroke registries.
The relative incidence of lacunar CI in Chinese patients was more common, but large-artery atherosclerotic CI was less common than in whites.
Hypertension was frequently seen in Cl patients, especially in those with lacunae (85%) and large-artery atherosclerosis (69%). (...)
