    Abstract:
    OBJECTIVE: To explore the relationship between risk factors for coronary heart disease (CHD) and coronary artery lesions. METHOD: Potential risk factors were studied in 341 patients underwent coronary angiography. RESULTS: (1) Coronary angiography showed coronary artery lesions in 214 patients (lesion group), and no lesion in 127 patients (non-lesion group). There was significant difference in age, past history of diabetes, family history of CHD, smoking history, high-density lipoprotein cholesterol (HDL-C), lower-density lipoprotein cholesterol (LDL-C), ratio of total cholesterol to HDL-C (TC/HDL-C), lipoprotein(a) [Lp(a)], fibrinogen (Fbg) and high-sensitivity C-reactive protein (hs-CRP) between two groups (P < 0.05). (2) There was significant correlation between severity of coronary artery lesions and hs-CRP, Lp(a), TC/HDL-C, Fbg, hyperlipidemia, TC, LDL-C and TG (with coefficients of correlation of 0.338, 0.250, 0.241, 0.207, 0.167, 0.147, 0.140 and 0.139; respectively, P < 0.05). (3) Analysis of receiver operating characteristics (ROC) curve for patients with coronary angiography and risk factors for CHD showed that the areas under ROC curve were 0.810, 0.669, 0.626, 0.625, 0.619 and 0.618 for hs-CRP, TC/HDL-C, Lp(a), Fbg, LDL-C and past history of hyperlipidemia, respectively. CONCLUSIONS: Past history of hyperlipidemia was a predictor for occurrence of CHD. Ratio of TC/HDL-C and blood level of Lp(a) could be used as predictors in screening for high blood lipid, which were much stronger than others. It is suggested that hs-CRP had an excellent predictive value in current coronary inflammatory lesions.
