In the previous studies shown that the cerebral arteriosclerosis has significant relationship with prognosis and mortality rate of stroke. The purpose of this using the computed tomography (CT) image of cerebral arteriosclerosis is to evaluate the correlation risk factor of cerebral arteriosclerosis, the relationship between stroke and giving appropriate prevention processing. This was a retrospective observational study of all patients who took brain computed tomography in Taipei Veterans General hospital from November 2005 to March 2006. One thousand eight hundred and thirty seven patients with a mean age of 66.28 years (20 to 98) were recruited into the study. From the results of CT image there are seven type of disease can be divided, namely, intracranial hemorrhage, cerebral infarction, lacunar infarction, the arteriosclerosis, calcification of blood vessel, old cerebrovascular accident and brain tissue atrophy, respectively. Five risk factors for the cerebral arteriosclerosis include diabetes (384 cases), hypertension (872 cases), the heart coronary artery disease (236 cases), hyperlipidemia (159 cases) and atrial fibrillation (81cases). The ratio of the cerebral arteriosclerosis was 25.5% in all patients; it suffers from diabetes (30.3%), hypertension (66.5%), the heart disease (16.5%), atrial fibrillation (9.0) and hyperlipidemia (9.0%). From the results show that the development of cerebral arteriosclerosis correlates significantly with ageing (OR=9.657; p<0.001), hypertension (OR= 2.583; p<0.001) and diabetes (OR= 2.029; p<0.001). For improving the prognosis and treatment of ischemic stroke, it is important to reduce the incidence of arteriosclerosis by diminishing the incidence of hypertension and diabetes mellitus.
