This prospective and cross-sectional study was conducted to assess the risk factors for coronary artery disease in the selected Korean Pateints.

We analyzed clinical parameters and biochemical parameters in 158 subjects; 98 subjects with significant coronary artery disease as proven by coronary angiography(stable angina pectoris : 55, unstable angina pectoris : 30, post-myocardial infarction angina pectoris : 13) and 58 normal subjects as proven by coronary angiography, from November 1993 to April 1994 in Seoul National University Hospital.

1) Old age, male gender, history of diabetes and smoking, high low density lipoprotein cholesterol level, high lipoprotein (a) level and high fibrinogen level were identified and risk factors for coronary artery disease on simple logistic regression analysis.

2) Lp(a) was positively related to fibrinogen(r=0.23), cholesterol(r=0.23) and low density lipoprotein cholesterol(r=0.28).

3) High fibrinogen level, old age, and male gender were independent risk factors of significant coronary artery disease in the selected Korean Population on multiple stepwise logistic regression analysis.

High fibrinogen level, old age, and male gender six were independent risk factors of significant coronary artery disease in the selected Korean Population of multiple stepwise logistic regression analysis.

These findings could not deny the role of cholesterol in coronary artery disease, but suggested that factors related to thrombosis and fibrinolysis, may play more important role in Korean patients coronary artery disease.
