Abstract |
BACKGROUND The incidence of type 2 diabetes mellitus is increasing annually and patient mortality is high. Coronary artery calcification is a predictor of coronary artery disease. Cardiovascular events, which are the main cause of death in type 2 diabetes patients, may be preventable by addressing risk factors associated with coronary artery calcification. We examined the relationships between coronary artery calcification, lipid profiles, and apolipoprotein levels. METHODS: We calculated the coronary calcium scores (CCS) of 254 subjects with type 2 diabetes (113 males, 141 females) via multi-detector row computed tomography (MDCT). Height, body weight, blood pressure, HbA1c, c-peptide, lipid profile and apolipoprotein were assessed concurrently. RESULTS: In patients with type 2 diabetes, Agatston score and apolipoprotein A-1 were significantly negatively correlated in both males and females (males P = 0.015, females P = 0.021). The negative correlation between Agatston score and apolipoprotein A-1 was retained for the entire patient sample after adjustments for age and sex (P = 0.022). Stepwise multiple regression anaylses with the Agatston score as the dependent variable indicate that apolipoprotein A-1 is a independent predictor (beta coefficient = -0.047, 95%CI = -0.072 ~ -0.021, P < 0.001) of coronary artery calcification. CONCLUSION: The results of our study suggest that apolipoprotein A-1 is a useful independent indicator of coronary artery calcification. |
