Study of relationship between cardiovascular risk factors and severity of coronary artery disease in patients undergoing coronary angiography / 中华老年医学杂志

ABSTRACT

Objective To evaluate the correlation between multiple cardiovascular risk factors and severity of coronary heart disease (CHD) in patients undergoing coronary angiography. Methods Seven hundred and twenty eight patients who underwent coronary angiography were selected from Qilu Hospital from October 2008 to December 2009. The clinical data about cardiovascular risk factors including age, gender, hypertension, smoking status, type 2 diabetes mellitus, dyslipidemia, high uric acid level, low total bilirubin level, and coronary angiography results were collected. The severity and extent of coronary stenosis was evaluated by ACC/AHA coronary scoring system and CHD was diagnosed by angiography. Analyses were achieved by multiple regression analysis. Results Multiple regression analysis showed that age, gender, hypertension, type 2 diabetes mellitus and low HDL-C were prominent predictors of severity and extent of coronary heart disease. DM was the primary controllable risk factor of CHD (OR=3. 1179, P=0. 005). Conclusions The age, gender,hypertension, type 2 diabetes mellitus and low HDL-C are correlated with angiographic severity and extent of CHD. Consequently, controlling these five risk factors is important in the intervention and prevention of CHD.
