Patients who had an experience of PTCA or CABG were excluded from the study. Control subjects were healthy adults who had normal EKG values, no chest pain and no past history of cardiac disease (100 control group). All subjects were free of serum lipid lowering drugs. Serum α-T and B-C were analysed using HPLC. In addition to antioxidant vitamins, serum lipids (total cholesterol, HDL, TG) were also measured. Each case and control was matched in terms of age and sex. And all the CAD risk factors such as blood pressure, smoking, alcohol, serum lipid profile and BMI were adjusted to determine pure effect(s) of α-T and B-C on the CAD.The concentrations of both α-T and B-C were significantly lower in the CAD group than those in control group (P<0.05); in CAD group, mean values of α-T and B-C were 11.9±7.2 (μg/ml), 35.8±3.1 (μg/dl) respectively. As for the levels of B-C, it shows inverse relation with age, but not for the α-T Ievels. Serum levels of both vitamins did not show any significant differences in terms of sex, but men have a tendency o higher levels of B-C,but lower levels of α-T展开更多
