The purpose of this study is to present the epidemiological data on patients with a stroke admitted to the severance hospital, Yonsei University College of Medicine (YUMC) and to investigate the significant risk factors of stroke.


Methods
We reviewed medical records of 532 patients with a stroke admitted to the hospital of from 1992 to 1996 retrospectively.


Results
The incidence was highest in the sixth decade. Ischemic stroke (64.3%) was more common than a hemorrhagic stroke (35.7%) and the thrombotic infarction was the leading type (28.3%) of all kinds of stroke. Middle cerebral arterial territory was the most commonly involved site for the thrombotic and embolic stroke. Of the intracerebral hemorrhages, basal ganglia (48.4%) was the most commonly involved site with was followed by the thalamus (24.2%), lobar (19.3%), and cerebellum (6.5%). In subarachnoid hemorrhages, the aneurysm was most frequently located in the middle cerebral artery (34.4%). The possible contributing factors of stroke were hypertension, hypercholesterolemia, cigarette smoking and diabetes mellitus. The common complications during hospitalization were the frozen shoulders, depression, pneumonia, reflex sympathetic dystrophy (RSD), and hydrocephalus.
