The purpose of this case-control study was done to examine the relationship among the cerebral infarction, blood lipids and homocysteine. We compared the components of blood lipids and homocysteine between cerebral infarction patients group (n=127) and controls group (n=158). We performed Pearson’s chi-square test and Student’s t-test for univariate analysis, Binary logistic regression for multivariate analysis to evaluate risk factors of cerebral infarction and Pearson’s correlation analysis to investigate correlation between blood lipids and homocysteine. The results were as follows. The blood levels of High density lipoprotein cholesterol(HDL-Chol) and Low density lipoprotein cholesterol (LDL-Chol) were significantly lower in patients group, while age, the blood levels of Triglyceride(TG) and homocysteine were significantly higher in patients group. Hypertension had a 4.62 odds ratio, TG≥150 ㎎/㎗ had a 2.33 odds ratio, HDL-Chol ≤40 ㎎/㎗ had a 6.85 odds ratio, but sex, DM, T-Chol, LDL-Chol had no direct relationship with odds ratio(non significant). In addition, among T-Chol and TG, HDL-Chol, LDL-Chol, they had positive correlation each other. Between TG and HDL-Chol had negative correlation each other. Homocysteine was not correlated with blood lipids adjusted for age and sex. These results suggest that low HDL-Chol and high TG may be risk factor of cerebral infarction. The correlation between homocysteine and blood lipids was not proven.y urther reserch on the subject is needed.
