Abstract: BACKGROUND: Conventional coronary artery disease (CAD) is the leading cause of morbidity and mortality in the general population. In recent years, multiple CAD promising risk factors have been reported and used for risk stratification. Lipoprotein(a) [LPA] concentration in plasma was shown associated with CAD risk and LPA genetic variants in different ethnic groups remains less clear. METHODS: We obtained data from 100 affected patients with established CAD and 100 healthy controls. We tested Body mass index (BMI), total cholesterol level (TC), systolic blood pressure (SBP), diastolic blood pressure (DBP), low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides (TG), fasting blood sugar (FBS) and two LPA (rs10455872 and rs3798220 SNPs) between cases and healthy controls. TaqMan SNP genotyping assays were performed to detect variants. RESULTS: Obtained data for BMI, TC, SBP, DBP, and LDL have significantly difference between two groups. Individually, the single SNPs were not associated with CAD in different analysis models. Also there was no significant difference in the incidence of CAD among cases carrying different genotypes of the two variants in LPA with p> 0.05. DISCUSSION: In this study patients with CAD, lipoprotein(a) concentrations and genetic variants showed no associations and we conclude that these variables are not useful risk factors to predict progression to disease is Iranian population. However, the prevalence and association of LPA SNPs with size of LPA and isoforms are highly variable and genetic background-specific. CONCLUSION: Our data did not indicate a relationship between genomic LPA variants (rs10455872 and rs3798220) and subsequent cardiovascular events in Iranian CAD patients. We did not confirm the association of the theses SNPs with CAD in our samples of Iranian patients. For the studied variants, our finding is consistent with reports which showed the lack of this genetic association in other populations.
