OBJECTIVE: To investigate the relationship between the risk factors of coronary artery disease and the severity of the coronary artery lesions. METHODS: A total of 446 consecutivey admitted patients were studied retrospectively. All patients suspected to have coronary artery disease and underwent a selective coronary angiography and a survey of risk factors during the hospitalization. RESULTS: Through Logistic regression analysis, advanced age, smoking, hyperlipidemia and course of diabetes mellitus were confirmed to be independent risk factors for coronary artery disease (OR = 1.02-1.23, P = 0.0406-0.0001). A significant correlation (F = 2.3130-19.2165, P = 0.1291-0.0001) between the severity of the coronary artery lesions and the age, the number of cigarettes in a day, the level of plasma lipids and the course of diabetes mellitus of the patients was found from the multiple regression analysis. CONCLUSIONS: Not only the development but also the severity of the coronary artery lesions is affected by the risk factors of advanced age, smoking, hyperlipidemia, and diabetes mellitus.
