Abstract:
BACKGROUND: In Korea, cerebrovascular accident (CVA) is the most significant cause of death among older people, and the incidence of cerebral hemorrhage is much higher than that of developed countries. There have been many investigations about the risk factors for CVA in both Korea as well as developed countries. A few papers reported various risk factors for cerebral hemorrhage in developed countries:however, well-designed studies of risk factors for the various causes of CVA were rare in Korea. Therefore, the purpose of this study was to compare the risk factors for the various causes of CVA and to evaluate the risk factors compared with age- and sex-matched control groups. In addition, duplex sonographic findings of the carotid artery were evaluated in patients with cerebral infarction. METHODS: One hundred and sixty-four patients admitted to the hospital in 1996 were enrolled. The four groups were divided based on the following states: cerebral infarction (n-63), cerebral hemorrhage (n-64), cerebral infarction with atrial fibrillation (n-19), and lacunar infarction (n-18). Major risk factors were compared with age- and sex-matched control groups and among CVA groups. Duplex sonography of the carotid artery was done in 14 patients with cerebral infarction. RESULTS: In multiple logistic regression analysis, patients with cerebral infarction had higher prevalence of diabetes mellitus and lower high density lipoprotein-cholesterol level than the control group, and hypertension showed borderline significance. Patients with cerebral hemorrhage had higher prevalence of hypertension, higher high density lipoprotein-cholesterol level, and more frequent prevalence of smoking compared with the control group. Patients with cerebral infarction showed lower high density lipoprotein-cholesterol, higher low density lipoprotein-cholesterol levels, more frequent diabetes mellitus, lower prevalence of hypertension and older age than patients with cerebral hemorrhage. Patients with cerebral infarction and atrial fibrillation showed only older age than patients with cerebral infarction only. There were no differences in risk factors between patients with cerebral infarction and lacuna infarction. Atheromatous plaque was found in 71% of patients with cerebral infarction. CONCLUSION: Metabolic abnormalities played more important role in the development of cerebral infarction and hemodynamic abnormalities in cerebral infarction. Sonographic examination of the carotid artery may be useful for predicting the occurrence of cerebrovascular accident in high risk patients.
