Abstract

Background and purpose: Patients with genetic background for high circulating oxidized low-density lipoprotein (oxLDL) levels might be at an increased risk of cerebrovascular disease (CVD). Methods: The association of oxLDL-variant rs676210 with CVD events was studied in patients undergoing coronary angiography (study A: N=2913 [271 cases]). We sought to replicate the results in a large genome-wide association study meta-analysis of ischaemic stroke (study B: N=3548 cases, 5972 controls). Results: In study A, the prevalence of hypertension, diabetes and >50% carotid stenosis as well as the levels of LDL cholesterol differed significantly between cases and controls. In a logistic regression model adjusted for the significant covariates, rs676210 associated with CVD events (p=0.030: odds ratio=1.29 [95% confidence interval 1.03-1.63] for risk allele G). In study B, rs676210 did not associate with the history of ischaemic stroke. Conclusions: The oxLDL levels increasing variant rs676210 associates with CVD events in patients undergoing coronary angiography.
