Purpose : As diet habits change and the elderly popuation increases conronary artery disease(CAD) has also increased. Recent ongoing studies on varous inflammatory indexes in acute coronary syndrome(ACS) are underway. Several study results have shown that total antioxidant status(TAS) was remarkably lower in unstable angina than in chronic stable angina and levels of interleukin-(IL-6), C-reactive protein(CRP), monocyte chemoattractant protein-1(MCP-1), P-selectin were reported to be elevated in unstable angina and acute myocardial infarction(AMI). In our study, we studied and compared the level changes of cytokines and inflammatory indexes that play important roles inside the blood vessel. Methods : Study subjects were patients who were admitted and underwent coronary angiography at the cardiology department in Soonchunhyang university hospital. Subjects were divided into 4 groups, a control group, a stable angina and unstable angina group and an acute myocardial infarction group. The clinical findings, TAS, inflammatory cytokines(P-selectin, MCP-1, IL-6), anti-inflammatory cytokines(IL-10), Homocysteine and CRP levels in each group were measured and compared. Results : The total number of study participants was 86 patients, with 26 patients in the control group, 21 patients with stable angina, 15 patients with unstable angina, and 24 patients with AMI. There were significant differences in the TAS among the 4 grouops. 1.7±0.51 mmol/L, 1.6±0.60 mmol/L, 1.4±0.20 mmol/L, 1.4±0.29 mmol/L respectively. IL-6 levels also showed a significant difference between groups, averaging 0.8±2.47 pg/ml, 2.7±3.77 pg/ml, 6.8±10.63 pg/ml, 10.9±17.43 pg/ml respectively. Homocysteine levels averaged 8.0±2.47 pg/ml, 6.8±10.63 pg/ml, 10.9±17.43 pg/ml restectively. Homocysteine levels averaged 8.0±1.0 μmol/L in the control group, 14.3±5.14 μmol/L in patients with stable angina, 16.0±4.66 μmol/L in patients with unstable angina, and 17.3±10.08 μmol/L in AMI patients. Conclusion : Compared to the control group, the TAS levels were significantly lower in patients with unstable angina and AMI. there was no difference between the control group and those with stable angina. IL-6 and homocysteine levels were also higher in patients with unstable angina and AMI. Therefore we concluded that measurements of TAS, IL-6 and homocysteine are useful in measuring the inflammatory index of coronary artery diseases and may be important factors in predicting the states and prognosis of cardiovascular disorders.
