[์˜๋ฌธ]This study was designed to determine the relationship between white blood cell(WBC) count and ischemic stroke, hemorrhagic stroke and total stroke and to see if WBC count was a significant predictor of outcomes independent of other biomarkers. Inflammation has been shown to play a role in atherosclerosis and cardiovascular disease. The WBC is a commonly performed clinical test, yet much remains to be learn about its variation in the general population and its value as a predictor rather than merely an indicator of disease.The research data used in this study was obtained from the National Health Insurance Corporation. The total number of subjects participating in the initial physical examination of this study was 412,653 without past history of hypertension, diabetes, cancer and cardiovascular disease. This document is based on revised International Classification of Disease, Ninth and Tenth Revision. The definition of stroke included ischemic stroke, hemorrhagic stroke and total stroke. In order to analyze the risk of white blood cell count on ischemic stroke, hemorrhagic stroke and total stroke, it used the Cox''s proportional hazard model.Based on the results of this study, WBC count was increased as the blood pressure, total cholesterol, fasting blood sugar, smoking and alcohol consumption except age were increased.After adjusted age, blood pressure, smoking, body mass index, fasting blood sugar, total cholesterol, alcohol consumption, Cox''s proportional hazard model was used to predict the mortality risk ratio of ischemic stroke, hamorrhagic stroke and total stroke as WBC count stratified six groups, <5.0, 5.0~<6.0, 6.0~<7.0, 7.0~<8.0, 8.0~<9.0, โ‰ฅ9.0ร—1,000cells/mmยณ, was increased.As WBC count indicates inflammation was increased by 1,000cells/mmยณ, mortality risk ratio of ischemic stroke and total stroke was increased.The stratum with the highest WBC count(โ‰ฅ9.0ร—1,000cells/mmยณ) had higher mortality risk ratio from ischemic stroke and total stroke respectively in total study population (hazard ratio๏ผปHR๏ผฝ, 2.007; 95% confidence interval๏ผปCI๏ผฝ,1.600-2.519 and HR, 1.464; 95% CI ,1.319-1.624), in men (HR, 1.737;,95% CI, 1.246-2.422 and HR 1.447;95% CI 1.234-1.697) and in women (HR, 2.307; 95% CI, 1.676-3.175 and HR, 1.468; 95% CI, 1.273-1.692) compared with the stratum with the lowest level (<5.0ร—1,000cells/mmยณ).On the other hand, the mortality risk ratio from hemorrhagic stroke didn''t show the relationship with WBC count and not show statistical significance.These results show that the WBC count is associated with ischemic stroke, but not associated with hemorrhagic stroke. This study shows that individuals with increased WBC count need to be monitored and managed in order to reduce the increased risk of ischemic stroke. This study indicates that if the measured WBC count are increased, healthcare should make every effort to encourage their patients to control the risk factors that lead to cardiovascular events. But WBC count is very fluctuant in acute or chronic inflammation and health conditions. The little evidence was presented about the relationship between inflammation and hemorrhagic stroke. In the future many similar studies were recommended repetitive. Furthermore, in subgroups of hemorrhagic stroke the deeper study is needed.prohibitio
