    Abstract:
    Increased concentration of low density lipoprotein (LDL) cholesterol or decreased level of high density lipoprotein (HDL) cholesterol are important risk factors for coronary atherosclerosis. However, an independent association of triglycerides (TG) with atherosclerosis is uncertain. The aim of this prospective study was to evaluate the relationship between serum lipid levels and the extent of coronary atherosclerosis in patients with suspected coronary artery disease (CAD) and no previous myocardial infarction who were not treated with lipids lowering therapy or low-lipid diet. The study was conducted in 141 patients (53.6 +/- 7.8 years old; 32 female) who underwent a routine coronary angiography for CAD diagnosis. A modified angiographic Gensini Score (GS) was used to reflect the extent of coronary atherosclerosis. Fasting serum lipid concentrations were determined using cholesterol esterase/peroxidase (CHOD/PAP) enzymatic method for total cholesterol and its fractions and lipase glycerol kinase (GPO/PAP) enzymatic method TG evaluation. The association of Gensini Score with variables characterising lipid profile was analysed with the use of Pearson correlation (r co-efficient; p value). GS was positively correlated with total cholesterol (r = 0.404; p < 0.001), LDL cholesterol (r = 0.484; p < 0.001 ) and TG (r = 0.235; p = 0.005). There was a negative correlation between Gensini Score and HDL cholesterol (r = -0.396; p < 0.001). In angina pectoris patients with no previous myocardial infarction, the extent of coronary atherosclerosis is positively correlated with pro-atherogenic lipids, i.e. total cholesterol, LDL cholesterol and TG and negatively correlated with antiatherogenic HDL cholesterol.
