Lectin-like ox-LDL receptor 1 (OLR1) contributes to the uptake and internalization of ox-&nbsp;LDL. Genetic polymorphisms have been associated with coronary artery disease (CAD). Here we explore&nbsp;the association of plasma levels of ox-LDL and 3&prime; UTR OLR1 (rs1050286) SNP with CAD risk and inhospital&nbsp;adverse outcomes.</h3> <h3></h3> <h3><em><strong>Methods:</strong></em> A case-control study enrolled 192 patients with ST-segment elevation myocardial&nbsp;infarction (STEMI), 100 patients with unstable angina, and 100 healthy controls. Baseline, clinical&nbsp;characteristics, and risk scores of the patients were determined. Plasma ox-LDL and other&nbsp;biochemical variables were measured. All subjects are genotyped for OLR1 (rs1050286) by RT-PCR with TaqMan SNP genotyping assay.</h3> <h3 style="text-align: justify;"><strong><em>Results:</em></strong> Plasma ox-LDL was higher with enhanced sensitivity and specificity in identifying patients with&nbsp;STEMI and was found as a significant independent risk factor for CAD in those two groups. Levels of&nbsp;ox-LDL were increased with increasing poor prognostic factors in STEMI patients that are associated&nbsp;with an increased incidence of some adverse events and in-hospital mortality. Elevated STEMI risk was&nbsp;associated with T allele of OLR1 (rs1050286) (odds ratio of 4.9, 95% CI: 2.6-9.4, p< 0.001). STEMI&nbsp;patients who have T allele exhibited higher risk scores, coronary multivessel narrowing, and elevated&nbsp;incidence of in-hospital major adverse clinical events.</h3> <h3 style="text-align: justify;"><em><strong>Conclusions:</strong></em> These results suggest that plasma ox-LDL, as well as T allele of ORL-1 (rs1050286),&nbsp;is associated with the increased risk for developing STEMI and the associated adverse clinical&nbsp;outcomes.</h3> Coronary artery disease, genotyping, OLR1, outcomes, Oxidized low-density lipoprotein. 537 553 http://rbmb.net/browse.php?a_code=A-10-839-1&slc_lang=en&sid=1 Hanan Sharaf El-Deen Mohammed 100319475328460012403 100319475328460012403 No Department of Internal Medicine, Faculty of Medicine, Assiut University, Assiut, Egypt.
