[Relationship between the risk factors of coronary artery disease and the severity of coronary artery lesions].
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.
